Auto-hemoterapia em orquiectomia de cães / Autohemotherapy in dogs' orchiectomy

A orquiectomia consiste na remoção dos testículos e, em animais, pode ser realizada por motivo eletivo ou terapêutico. A cirurgia eletiva faz parte da guarda responsável de cães e gatos e é um dos procedimentos mais realizados na medicina veterinária, incluindo mutirões de castração onde a redução de custos é importante. A auto-hemoterapia (AHT) vem sendo aplicada em animais, inclusive em acupontos, com o intuito de produzir efeitos imunoestimulantes. Neste contexto, este estudo utilizou AHT, durante o período pós-operatório imediato, em acupontos de cães submetidos à orquiectomia eletiva sem a aplicação de antibióticos. Os resultados obtidos foram comparados com dados referentes a outro grupo de animais, os quais foram orquiectomizados e previamente tratados com antibiótico sistêmico. Todos os animais foram acompanhados clinicamente e foram feitos hemogramas nos períodos pré e pós-operatório, assim como o registro de infecções e outras intercorrências relacionadas ao procedimento cirúrgico. Considerando os 20 cães usados no estudo, não houve ocorrência de infecção ou processo inflamatório nos animais após o procedimento cirúrgico. Além disso, alterações hematológicas significativas não foram observadas entre os grupos e entre os períodos pré e pós-operatório de ambos os grupos. Desta forma, conclui-se que a auto-hemoterapia associada à acupuntura pode representar uma alternativa para um protocolo cirúrgico sem antibióticos em cirurgia eletiva de orquiectomia em animais hígidos.

The orchiectomy is the removal of the testicles and, in animals, can be performed due to by elective or therapeutic reasons. Elective surgery is part of the responsible ownership of dogs and cats and is one of the most performed procedures in veterinary medicine, including castration efforts where cost reduction is important. Autohemotherapy (AHT) has been applied in animals, including acupoints, to produce immunostimulatory effects. In this context, this study used AHT, during the immediate postoperative period, in acupoints of dogs submitted to elective orchiectomy without the use of antibiotics. The results obtained were compared to data from another group of animals, which were orchiectomized and previously treated with a systemic antibiotic. All animals were clinically monitored and hemograms were performed during the pre and post-operatory period, as well as the registration of infections and other complications related to the surgical procedure. Regarding the 20 dogs used in the study, there was no occurrence of infection or inflammation in the animals after the surgical procedure. In addition, significant hematologic alterations were not observed between groups and between pre- and post-operatory periods in both groups. Therefore, it is concluded that autohemotherapy associated with acupuncture may represent an alternative for a surgical protocol without antibiotics in elective orchiectomy surgery in healthy animals.

Microbiome and antimicrobial resistance in members of the Enterobacteriaceae family from vaginal and preputial mucous isolates of stray dogs

Background: Contact between humans and pets, mainly dogs and cats, has been increasing in recent years, which may result in the spread of infectious agents to new hosts and even to the environment, causing emergencies of national and international interest. The aim of this work was to understand the phenotypic profile of bacteria of the Enterobacteriaceae family of vaginal and preputial mucous of stray dogs from a border region. Materials, Methods & Results: Swab samples from the vaginal and preputial mucosa of stray dogs from two border regions were collected for later bacterial isolation, biochemical identification of bacterial isolates, susceptibility tests to different antimicrobials, and determination of the bacterial resistance index. Samples were collected from 70 animals, was possible to isolate 88 samples, of which 36 (40.9%) presented isolates of Gram-negative bacteria, with Escherichia coli being the most prevalent species (44.8%), followed by Obesumbacterium proteus in eight (27.5%); Enterobacter aerogenes and Enterobacter cloacae in two (6.8%); and Erwinia herbicola, Koserella trabulsii, Proteus mirabilis, and Serratia rubidaea (3.4%) from one isolate. The most resistant antimicrobials Clindamycin (100%), Metronidazole (100%), Oxacillin (100%), and Penicillin (100%) were tested against the vaginal and preputial samples and when the multidrug resistance index of the isolates was analyzed, all were classified as presenting a public health risk. Discussion: The results of this work suggest that stray dogs may be considered potential reservoirs of resistant pathogenic microorganisms, enabling future health problems due to the close coexistence of tutors with their dogs. It is known that the microorganisms that inhabit a certain environment or a specific part of the body are collectively called microbiomes. More specifically, some of them are bacteria that inhabit the reproductive mucous...

Negative results for Borrelia burdgorferi in cows and ticks from a border region between Brazil and Paraguay: a case report / Resultados negativos para Borrelia burgdorferi em vacas e carrapatos de região fronteiriça entre Brasil e Paraguai: relato de Caso

Lyme borreliosis is an infectious disease caused by bacteria of the genus Borrelia. In ruminants, most infections are asymptomatic, but the animals can present myalgia, lameness, laminitis, arthritis, synovitis, neurological symptoms, and also decreased production and abortion. The objective was to investigate Borrelia burgdorferi DNA in cows and cattle ticks on a small dairy farm in a border region. Blood samples and ticks were collected from Holstein cows with a history of decreased milk production and abortions. Borrelia burgdorferi DNA was extracted from blood samples using a commercial extraction kit, and from ticks using an alkaline hydrolysis solution for subsequent nested-PCR. Serum and tick samples did not present Borrelia burgdorferi DNA, and 100% of the ticks were identified as Rhipicephalus (Boophilus) microplus. Although this study shows negative results it contributes to understanding the epidemiology of this etiological agent in Paraná and in Brazil, since there are few studies on bovine species. The negative results of this work demonstrate that the animals and ticks researched were not exposed to Borrelia burgdorferi, however, as it isa property located in a border region, the sanitary monitoring of the herd must be performed constantly since this is a region. vulnerable to the entry of potential threats to human, animal and environmental health from vectors and pathogenic microorganisms, given the large extension of the land border with the neighboring country and which also has different health status.

A borreliose de Lyme é uma doença infecciosa causada por bactérias do gênero Borrelia. Nos ruminantes, a infecção é assintomática, mas os animais podem apresentar mialgia, claudicação, laminite, artrite, sinovite, sintomas neurológicos e também diminuição da produção e do aborto. O objetivo foi investigar o DNA de Borrelia burgdorferi em vacas e carrapatos de uma pequena propriedade rural de gado leiteiro em uma região de fronteira. Amostras de sangue e carrapatos foram coletados de vacas da raça Holandesa com histórico de diminuição da produção de leite e abortos. O DNA de Borrelia burgdorferi foi extraído de amostras de sangue usando um kit de extração comercial e de carrapatos usando uma solução de hidrólise alcalina para subsequente nested-PCR. Amostras de soro e carrapato não apresentaram DNA de Borrelia burgdorferi, e 100% dos carrapatos foram identificados como Rhipicephalus (Boophilus) microplus. Embora este estudo apresente resultados negativos o mesmo contribui para o entendimento da epidemiologia desse agente etiológico no Paraná e no Brasil, uma vez que existem poucos estudos sobre espécies bovinas. Os resultados negativos deste trabalho demonstram que os animais e carrapatos pesquisados não foram expostos a Borrelia burgdorferi, no entanto, por se tratar de uma propriedade localizada em uma região de fronteira, o monitoramento sanitário do rebanho deve ser realizado constantemente, pois é uma região vulnerável à entrada de ameaças potenciais à saúde humana, animal e ambiental por vetores e microrganismos patogênicos, dada a grande extensão da fronteira terrestre com o país vizinho e que também apresenta diferentes condições de saúde.

Relato de dois casos de mastite pós-parto em cadelas / Report of two cases of postpartum mastitis in bitches

Algumas das urgências reprodutivas presentes na espécie canina incluem distocias, piometra e mastite, sendo esta última, a inflamação bacteriana de uma ou mais glândulas mamárias, secundária ao parto em cadelas. Objetivou-se, com o presente relato, descrever dois casos de mastite em cadelas sem raça definida. Os dois casos foram diagnosticados por meio da anamnese e exame clínico, porém, no segundo caso, foram realizados exames complementares (hemograma; cultura e antibiograma). O tratamento do primeiro caso foi feito com cefalexina e tintura de iodo topicamente nas tetas. Para o segundo caso, em decorrência da realização da cultura e antibiograma, detectou-se sensibilidade a alguns antibióticos e resistência a outros. Assim, o animal foi tratado com amoxicilina associada a ácido clavulânico. Em ambos os casos houve recuperação completa das pacientes. O diagnóstico precoce da enfermidade é importante devido ao caráter emergencial da doença. O tratamento, baseado em antimicrobianos, foi eficiente e adequado para os casos em questão.

Some of the reproductive urgencies present in the canine species include dystocia, pyometra and mastitis, the latter being bacterial inflammation of one or more mammary glands, secondary to delivery in bitches. The objective of this report was to describe two cases of canine mastitis diagnosed in mongrel bitches. The two cases were diagnosed by anamnesis and clinical examination, but in the second case complementary exams were performed (hemogram, culture and antibiogram). Treatment of the first case included cefalexin, and iodine tincture was used in the tits. For the second, as a result of the culture and antibiogram, sensitivity to some antibiotics and resistance to others were detected, so the animal was treated with amoxicillin associated to clavulanic acid. In both treatments, the bitches presented recovery. The early diagnosis of the disease is important due to emergential characteristic. The treatment, based in antimicrobials, was efficient and appropriated for the cases.

Identification of enterobacteria in free-living nonhuman primates in an urban park in the northern Region of the State of Paraná, Brazil / Identificação de enterobactérias em primatas não-humanos de vida livre em um parque urbano na Região Norte do Estado do Paraná, Brasil

Populations of nonhuman primates are often considered to be a link in the chain of emerging infectious diseases, as they are reservoirs for different zoonotic pathogens. The objective of this study was to identify the presence of bacteria from the family Enterobacteriaceae in free-living nonhuman primates. The research was carried out in an urban park located in a city in the northern region of the State of Paraná, Brazil. The animals were captured in Tomahawk-type traps and chemically restrained, being oral and rectal samples collected with sterile swabs. For bacterial isolation, the samples were seededon MacConkey agar plates and grown under anaerobic conditions. The subsequent identification was conducted using a commercial biochemical kit. Sixteen primates identified as black-capuchin-monkeys (Sapajus nigritus) were captured. Seven different enterobacterial species were identified from the oral cavity swabs: six Escherichia coli (42.9%), three Kluyvera species (21.40%), one Serratia rubidaea(7.14%), one Enterobacter aerogenes (7.14%), one Enterobacter cloacae (7.14%), one Hafnia alvei (7.14%), and one Erwinia herbicola (7.14%). Seven different species were identified from the rectal swabs: six Escherichia coli (40%), three Kluyvera species (20%), two Enterobacter aerogenes (13.32%),one Erwinia herbicola (6.67%), one Serratia rubidaea (6.67%), one Pragia fontium (6.67%), and one Edwardsiella tarda (6.67%). The results indicate that the isolated bacteria belong mainly to the human microbiota and had crossed the interspecific barrier, contaminating the nonhuman primates.(AU)

As populações de primatas não humanos frequentemente são consideradas um elo na cadeia de doenças infecciosas emergentes, por constituírem reservatórios que propiciam o surgimento de diferentes patógenos zoonóticos. O objetivo deste trabalho foi identificar a presença de bactérias da família Enterobacteriaceae em primatas não humanos de vida livre. O estudo foi realizado em um parque urbano localizado em uma cidade da região norte do Estado do Paraná. Os animais foram capturados em armadilhas do tipo Tomahawk e submetidos a contenção farmacológica para colheita de amostras da microbiota oral e retal com zaragatoas estéreis. Para o isolamento bacteriano as amostras foram semeadas pela técnica de esgotamento em placas contendo ágar MacConkey, com posterior identificação por testes bioquímicos utilizando kit comercial. Foram capturados 16 primatas não humanos identificados como Sapajus nigritus (macaco-prego). Na cavidade oral foi possível identificar sete diferentes espécies de bactérias, sendo seis (42,9%) Escherichia coli, três espécies de Kluyvera (21,40%), uma (7,14%) Serratia rubidae, uma (7,14%) Enterobacter aerogenes, uma (7,14%) Enterobacter cloacae, uma (7,14) Hafnia alvei e uma (7,14%) Erwinia herbicola. No reto foi possível identificar sete diferentes espécies de bactérias, sendo seis (40%) Escherichia coli, três espécies de Kluyvera (20%), duas (13,32%) Enterobacter aerogenes, uma (6,67%) Erwinia herbicola, uma (6,67%) Serratia rubidae, uma (6,67%) Pragla fotiun e uma (6,67%) Edwardsiella tarda. Os resultados indicam que as bactérias isoladas são pertencentes principalmente à microbiota humana, e estão ultrapassando a barreira interespecífica e contaminando os primatas.(AU)

Obstrução uretral aguda causada por tumor venéreo transmissível em um cão / Acute urethral obstruction due to transmissible venereal tumor in a dog

Background: Transmissible venereal tumor (TVT) is a sexually transmitted, contagious, round cell neoplasm that affects mainly the external genital organs of dogs of both sexes. Canine TVT is practically the only tumor transmitted by cellular transplantation under natural conditions. The tumor occurs in all dog breeds and in various parts of the world, especially in the tropics and subtropics. Sexually active dogs that roam are at increased risk of acquiring the infirmity. The diagnosis is clinical, and confirmed by cytology. The most effective treatment is chemotherapy with vincristine. The aim of this report is describes a case of one male dog with an acute urethral obstruction caused by TVT. Case: In a Veterinary Medical Teaching Hospital (VMTH), a dog of unknown age was admitted. Volunteers from an animal protection institution rescued the dog from the streets after information from residents. Upon admission in the VMTH, the dog had an acute urethral obstruction, detected on clinical examination. Cystocentesis was performed to relieve the condition. Complete clinical examination and blood count were performed. Hematological examination revealed anemia and thrombocitopeny. The clinical examination revealed a swelling in the preputial area, and penile exposure was not possible. Because of this it was not possible to place the urethral catheter in the animal. However, preputial fistula and a friable, bleeding mass suggestive of a TVT were detected. For penile inspection and correction of the obstruction, the dog was submitted to a surgical procedure with an incision in the preputial midline. After the incision was made, several masses with a friable and bleeding appearance were found. The masses that prevented the urinary flow were removed and, cleansed with a physiological solution. The skin was sutured to restore the normal anatomy. In the same procedure, the dog was neutered. Cytological examination of the masses confirmed the diagnosis of TVT. […](AU)

Anti-Rickettsia rickettsii antibodies in capybaras (Hydrochoerus hydrochaeris Linnaeus, 1766) from an agricultural landscape in Araras, São Paulo, Brazil / Anticorpos anti-Rickettsia rickettsii em capivaras (Hydrochoerus hydrochaeris Linnaeus, 1766) de uma de uma região agrícola de Araras, São Paulo, Brasil

Spotted fever is a typically endemic infectious disease caused by rickettsiae from the spotted fever group, of which Rickettsia rickettsii is the main etiologic agent. It presents high mortality rates in Brazil, with transmission to humans or animals through the bite of infected ticks. The capybara (Hydrochoerus hydrochaeris) is an important reservoir for Rickettsia spp.; these bacteria can circulate in an infected animal presenting only fever as a clinical sign of the disease, as demonstrated by experimental infection. Considering the high zoonotic potential and the damage caused to human, animal, and environmental health, this study searched for anti-Rickettsia rickettsii antibodies in capybaras from an agricultural landscape in the city of Araras, State of São Paulo, Brazil. The indirect immunofluorescence (IFA) technique was used to detect anti-R. rickettsii antibodies. From the 28 serum samples tested using IFA, 18 (64.28%) were considered reactive, with antibody titers ranging from 256 to 2048. Seven (38.88%) samples presented titers of 256, three (16.67%) with titers of 512, five (27.78%) with titers of 1024, and three (16.67%) with titers of 2048. However, it was not possible to significantly associate gender to these serologic results. These results demonstrate that at some point during their lives, the studied capybaras were exposed to the etiologic agent, but it is impossible to know when this occurred. Further studies need to be performed to clarify which serological titers ensure an infection in capybaras, basedon clinical and laboratory assessment of rickettsemia, and to establish the relationship between titers and the chronicity of disease. This is necessary owing to the possibility of cross-reactions with other rickettsiae species of the same subgroup, leading to the need for molecular tests to confirm diagnosis.

A febre maculosa é uma doença infecciosa, causada por rickéttsias do Grupo da Febre Maculosa, que geralmente se desenvolve em caráter endêmico e tem como principal agente etiológico Rickettsia rickettsii. Apresenta elevadas taxas de letalidade no Brasil, e a transmissão do agente ao homem ou animal ocorre pela picada de carrapatos infectados. A capivara (Hydrochoerus hydrochaeris) é um importante reservatório de Rickettsia spp., e por meio de infecção experimental demonstrou-se sua capacidade de mantê-la circulante no organismo, sem apresentar sinais clínicos da doença. Considerando o elevado potencial zoonótico e os prejuízos causados na saúde única por esse agente, este trabalho teve o objetivo de detectar anticorpos anti-Rickettsia rickettsii em capivara (Hydrochoerus hydrochaeris) de um bosque urbano de Araras, São Paulo, Brasil. Foi utilizada a técnica de imunofluorescência indireta (IFA) para detectar anticorpos anti-R. rickettsii. Das 28 amostras de soro testadas na IFA, 18 (64,28%) foram consideradas reagentes com títulos de anticorpos variando de 256 a 2048, sendo que sete (38,88%) amostras apresentaram títulos de 256, três (16,67%) títulos de 512, cinco (27,78%) títulos de 1024 e três (16,67%) títulos de 2048 e não foi possível a associação da variável sexo (p?0.05) com os resultados sorológicos para Rickettsia rickettsii. Outros estudos serão necessários para esclarecer que títulos sorológicos na IFA podem assegurar a positividade da infecção na capivara, a partir deavaliação clínica e laboratorial frente à rickettsemia, e estabelecer a relação entre títulos e a cronicidade da doença. Isso decorre da possibilidade de ocorrência de reações cruzadas com outras espécies de rickéttsias dos mesmos subgrupos, levando à necessidade da realização de testes moleculares para se confirmar o diagnóstico para a enfermidade.

After the incision was made, several masses with a friable and bleeding appearance were found. The masses that prevented the urinary flow were removed and, cleansed with a physiological solution. The skin was sutured to restore the normal anatomy. In the same procedure, the dog was neutered. Cytological examination of the masses confirmed the diagnosis of TVT. […]

Anti-Rickettsia rickettsii antibodies in capybaras (Hydrochoerus hydrochaeris Linnaeus, 1766) from an agricultural landscape in Araras, São Paulo, Brazil / Anticorpos anti-Rickettsia rickettsii em capivaras (Hydrochoerus hydrochaeris Linnaeus, 1766) de uma de uma região agrícola de Araras, São Paulo, Brasil

Spotted fever is a typically endemic infectious disease caused by rickettsiae from the spotted fever group, of which Rickettsia rickettsii is the main etiologic agent. It presents high mortality rates in Brazil, with transmission to humans or animals through the bite of infected ticks. The capybara (Hydrochoerus hydrochaeris) is an important reservoir for Rickettsia spp.; these bacteria can circulate in an infected animal presenting only fever as a clinical sign of the disease, as demonstrated by experimental infection. Considering the high zoonotic potential and the damage caused to human, animal, and environmental health, this study searched for anti-Rickettsia rickettsii antibodies in capybaras from an agricultural landscape in the city of Araras, State of São Paulo, Brazil. The indirect immunofluorescence (IFA) technique was used to detect anti-R. rickettsii antibodies. From the 28 serum samples tested using IFA, 18 (64.28%) were considered reactive, with antibody titers ranging from 256 to 2048. Seven (38.88%) samples presented titers of 256, three (16.67%) with titers of 512, five (27.78%) with titers of 1024, and three (16.67%) with titers of 2048. However, it was not possible to significantly associate gender to these serologic results. These results demonstrate that at some point during their lives, the studied capybaras were exposed to the etiologic agent, but it is impossible to know when this occurred. Further studies need to be performed to clarify which serological titers ensure an infection in capybaras, basedon clinical and laboratory assessment of rickettsemia, and to establish the relationship between titers and the chronicity of disease. This is necessary owing to the possibility of cross-reactions with other rickettsiae species of the same subgroup, leading to the need for molecular tests to confirm diagnosis.(AU)

A febre maculosa é uma doença infecciosa, causada por rickéttsias do Grupo da Febre Maculosa, que geralmente se desenvolve em caráter endêmico e tem como principal agente etiológico Rickettsia rickettsii. Apresenta elevadas taxas de letalidade no Brasil, e a transmissão do agente ao homem ou animal ocorre pela picada de carrapatos infectados. A capivara (Hydrochoerus hydrochaeris) é um importante reservatório de Rickettsia spp., e por meio de infecção experimental demonstrou-se sua capacidade de mantê-la circulante no organismo, sem apresentar sinais clínicos da doença. Considerando o elevado potencial zoonótico e os prejuízos causados na saúde única por esse agente, este trabalho teve o objetivo de detectar anticorpos anti-Rickettsia rickettsii em capivara (Hydrochoerus hydrochaeris) de um bosque urbano de Araras, São Paulo, Brasil. Foi utilizada a técnica de imunofluorescência indireta (IFA) para detectar anticorpos anti-R. rickettsii. Das 28 amostras de soro testadas na IFA, 18 (64,28%) foram consideradas reagentes com títulos de anticorpos variando de 256 a 2048, sendo que sete (38,88%) amostras apresentaram títulos de 256, três (16,67%) títulos de 512, cinco (27,78%) títulos de 1024 e três (16,67%) títulos de 2048 e não foi possível a associação da variável sexo (p?0.05) com os resultados sorológicos para Rickettsia rickettsii. Outros estudos serão necessários para esclarecer que títulos sorológicos na IFA podem assegurar a positividade da infecção na capivara, a partir deavaliação clínica e laboratorial frente à rickettsemia, e estabelecer a relação entre títulos e a cronicidade da doença. Isso decorre da possibilidade de ocorrência de reações cruzadas com outras espécies de rickéttsias dos mesmos subgrupos, levando à necessidade da realização de testes moleculares para se confirmar o diagnóstico para a enfermidade.(AU)

Toxoplasmosis, leptospirosis, and brucellosis seroepidemiology in veterinary medical students and their relation with unique health / Soroepidemiologia da toxoplasmose, leptospirose e brucelose em acadêmicos de medicina veterinária e sua relação com a saúde única

Toxoplasmosis, leptospirosis, and brucellosis are global zoonoses, with humans as accidental participants in their transmission cycles. The can also be considered occupational diseases, because certain professionals are at greater risk of contact and infection by such zoonoses. These three diseases have different epidemiological characteristics because of the distinct environmental, social, cultural, and economic conditions where these pathogens circulate. Because of the importance of these diseases and their associations with specific occupations, we performed a seroepidemiological survey of Toxoplasma, Leptospira, and Brucella antibodies, with an analysis of the association between positive serum and certain occupational and environmental variables, in students of a veterinary medicine course (1st, 2nd, 3rd, 4th, and 5th year) in a university in the northwestern region in the state of Paraná, Brazil. From May to November 2014, blood samples were collected from 157 volunteers by professionals trained in nursing and biomedicine from the same university as the veterinary students. At the time of blood collection, the students did not present any clinical signs of the three diseases of interest. To detect antiToxoplasma gondii, anti-Leptospira spp., and anti-Brucella antibodies, indirect immunofluorescence test (IIF), microscopic agglutination test (MAT), fast agglutination test (a screening test), and enzymelinked immunosorbent assay (ELISA) were performed. To determine variables associated with these infections, the students were interviewed to complete an epidemiological questionnaire with environmental, behavioral, and occupational information. The associations between these variables and infections were assess by chi-square or Fischer’s exact tests, with a 5% significance level (α)...

A toxoplasmose, leptospirose e a brucelose são zoonoses de ampla distribuição mundial, tendo o homem como participante acidental da sua cadeia epidemiológica, entretanto, podem se apresentar como doenças ocupacionais, em diferentes categorias profissionais, despertando grande preocupação, por estarem constantemente expostos ao risco de contato e contagio com essas zoonoses. Estas três enfermidades possuem características epidemiológicas distintas, como reflexo das diferenças ambientais, sociais, culturais e econômicas encontradas em cada localidade. Considerando a importâncias destas três enfermidades e sua relação com o aspecto ocupacional o objetivo deste trabalho foi realizar um levantamento soroepidemiológico para toxoplasmose, leptospirose e brucelose e identificar variáveis ocupacionais e ambientais relacionadas a estas três enfermidades em acadêmicos do curso de medicina veterinária de uma universidade da região noroeste do estado do Paraná, Brasil.

Leptospirosis and brucellosis seroepidemiology in sheep and dogs from non-mechanized rural properties in the northwestern region in the state of Paraná / Soroepidemiologia da leptospirose e brucelose em ovinos e cães de propriedades rurais não tecnificadas da região noroeste do estado do Paraná

Sheep breeding has been important in agribusiness, transforming the Brazilian productive scenario. However, it is still deficient due to the damages caused by infectious diseases. Leptospirosis is a severe disease with global distribution, caused by bacteria from the Leptospira genre affecting both humans and animals. The general infection is unapparent, or its clinical signs, when present, are similar to other infections. Brucellosis is an infectious disease caused by bacteria from the Brucella genre responsible for reproductive disorders in animals, especially ruminants. The purpose of this paper was to seroepidemiological study of Leptospira spp. and Brucella ovis in sheep and dogs from nonmechanized rural properties from the northwestern region in the state of Paraná, Brazil. In order to detect anti-Leptospira antibodies, microscopic agglutination (MAT) was performed. For anti-Brucella antibodies, the agar gel immunodiffusion assay (AGID) was performed. From the total 542 samples from sheep sera analyzed, 11.25% were considered reagent to Leptospira spp. and 18.26% to Brucella ovis. From the 36 dog samples, 25% were reagent to MAT and AGID. From the 32 properties analyzed, 75% were considered positive for leptospirosis and 56.25% for brucellosis. Antibodies against the most probable serovars were Hardjo (34.42%) and Butembo (44.44%) in sheep and dogs, respectively, and the variable exchange of animals among properties was associated to leptospiric infection (p=0.028) in sheep. Leptospirosis and brucellosis are present in the sheep herd and dogs in the rural properties studied, and such result is a warning of the zoonotic importance and the need to establish sanitary programs directed to these animal species.

A ovinocultura tem se destacado no agronegócio, transformando o cenário produtivo do Brasil, porém ainda possui uma deficiência devido aos danos causados por doenças infecciosas. A leptospirose é uma doença grave de distribuição mundial causada por bactérias do gênero Leptospira que afeta o homem e os animais. A infecção geralmente é inapetente, ou os sinais clínicos, quando presentes, são similares aos de outras infecções. A brucelose é uma enfermidade infecciosa causada por bactérias do gênero Brucella responsáveis por desordens reprodutivas nos animais, especialmente nos ruminantes. O objetivo deste trabalho foi realizar um estudo soroepidemiológico de Leptospira spp. e Brucella ovis ovinos e cães de propriedades rurais não tecnificadas da região noroeste do estado do Paraná, Brasil. Para detecção de anticorpos anti-Leptospira foi realizada a soroaglutinação microscópica (SAM), e para anticorpos anti-Brucella, a prova de imunodifusão em gel de ágar (IDGA). Das 542 amostras de soro ovino analisadas, foram consideradas reagentes 11,25% para Leptospira spp. e 18,26% para Brucella ovis. Das 36 amostras de cães, 25% foram regentes a SAM e IDGA. Das 32 propriedades, 75% foram consideradas positivas para leptospirose e 56,25% para brucelose. Os anticorpos contra os sorovares mais prováveis foram Hardjo (34,42%) e Butembo (44,44%) em ovinos e cães respectivamente, e a variável troca de animais entre propriedades foi associada à infecção leptospírica (p=0,028) nos ovinos. A leptospirose e a brucelose estão presentes no rebanho ovino e nos cães das propriedades rurais estudadas, e este resultado serve de alerta à sua importância zoonótica e a necessidade de estabelecer programas sanitários direcionados a esta espécie animal.

Detection of extended spectrum beta-lactamases and resistance in members of the Enterobacteriaceae family isolated from healthy sheep and dogs in Umuarama, Paraná, Brazil / Detecção de beta-lactamases de espectro estendido e resistência as quinolonas mediada por plasmídeos em membros da família Enterobacteriaceae isolados de ovinos e cães sadios de propriedades rurais da região de Umuarama, Paraná, Brasil

Bacterial resistance is a primary public health concern worldwide. Within this context, pets and breeding animals act as reservoirs for multidrug-resistant bacteria (MR), such as those producing extended spectrum beta-lactamases (ESBL) and those presenting plasmid-mediated quinolone resistance (PMQR). The aim of this study was to detect the presence of ESBL and PMQR in members of the Enterobacteriaceae family, isolated from healthy sheep and dogs from non-intense farming rural properties in the Umuarama region of Paraná, Brazil. A total of 81 oral and rectal swabs from dogs and sheep from 11 small rural properties were analyzed. These swabs were inoculated in tubes containing brain heart infusion broth (BHI), and the resulting cultures were inoculated on MacConkey agar (MAC) supplemented with 10 μg/mL cefotaxime for the selection of ESBL producers. The cells were also plated on MAC supplemented with 50 μg/mL nalidixic acid for selecting quinolone-resistant enterobacteria. The bacterial isolates were subjected to biochemical identification tests, antibiograms, double-disk synergic tests, and polymerase chain reaction analysis for resistance-inducing genes (blaESBL, qnr, and genes encoding efflux pump and acetylases). Four (5.00%) bacterial isolates (3 Escherichia coli and 1 Morganella morganii) resistant to cephalosporins and/or quinolones were identified; of these, three (75%) isolates were from sheep and one (25%) from a dog. These findings indicate the presence of MR bacteria in the normal microbiota of the animals studied. Animals colonized with such bacteria can contribute to the dissemination of antimicrobial resistance to other animals, environment, and/or human beings and can harbor endogenous infections in unfavorable conditions, which have poor prognosis due to the limited therapeutic options.(AU)

Resistência bacteriana é considerado o maior problema de saúde pública mundial da atualidade, sendo os relatos de infecções e surtos causados por bactérias multirresistentes cada vez mais frequentes na clínica veterinária e humana. Neste contexto, animais de companhia e criação podem atuar como reservatório de bactérias multirresistentes, como as produtoras de beta-lactamases de espectro estendido (ESBL) e as que apresentam resistência as quinolonas mediada por plasmídeos (PMQR). O objetivo deste trabalho foi detectar beta-lactamases de espectro estendido e resistência as quinolonas mediada por plasmídeos em membros da família Enterobacteriaceae isolados de ovinos e cães de propriedades rurais não tecnificadas da região de Umuarama, Paraná, Brasil. Foram analisados 81 swabs de cães e ovinos provenientes de 11 pequenas propriedades rurais da região de Umuarama (PR). Os swabs foram inoculados em caldo Brain Heart Infusion (BHI) e o crescimento obtivo foi em seguida semeado em placas de Petri contendo ágar MacConkey (MC) acrescido de cefotaxima 10 μg/mL para seleção de bactérias gram-negativas produtoras de ESBL; e placas contendo MC acrescido de ácido nalidíxico 50 g/mL para seleção de bactérias gram-negativas resistentes as quinolonas. Os isolados bacterianos obtidos foram submetidos a testes de antibiograma pelo método de disco-difusão em ágar, teste sinérgico do duplo-disco e reação em cadeia da polimerase (PCR) para genes que conferem resistência do tipo ESBL e para quinolonas. Dos 81 swabs coletados foi possível detectar quatro (4,97%) isolados bacterianos (3Escherichia coli e 1 Morganellamorganii) resistentes a cefalosporinas e/ou quinolonas. Destes isolados, três (75%) eram de ovinos e um (25%) de cão. Os resultados encontrados indicam a presença de cepas multirresistentes na microbiota normal dos animais estudados.[...](AU)
