Background: Bacterial resistance is a fundamental aspect of One Health, which is defined as the inseparable unity of animal, human, and environmental health. Epidemiological surveillance on the spread of bacterial resistance in animals and their derived products is essential given that meat, milk, and dairy products can carry resistant microorganisms that may reach humans through the food chain either by direct consumption or by handling the product. To eliminate the scarcity of information, it is necessary to characterize the epidemiological situation in terms of bacterial resistance in dairy production in northeastern Brazil. Thus, the objective of this study was to determine the frequency and antimicrobial susceptibility profile of bacteria isolated from goat milk samples from some municipalities in the Brazilian state of Sergipe. Materials, Methods & Results: The study included 28 goat farms in 4 municipalities of the Semiarid region of the State of Sergipe in Northeastern Brazil, namely Canindé de São Francisco (n = 11), Nossa Senhora da Glória (n = 6), Poço Verde (n = 6), and Porto da Folha (n = 5). All lactating does of each herd (n = 263) aged >1 year were, sampled randomly by non-probabilistic convenience sampling. Milk samples were collected from both teats, resulting in 526 samples in total. Bacterial culturing and isolation were performed, followed by antimicrobial susceptibility profile analysis to the following active principles: amoxicillin with and without clavulanic acid, amikacin, ampicillin with sulbactam, ciprofloxacin, cefalexin, cefalotin, ceftriaxone, chloramphenicol, doxycycline, enrofloxacin, gentamicin, levofloxacin, ofloxacin, penicillin G, and tetracycline. A survey form was used to obtain zootechnical information for each farm. Data are described as absolute and relative frequencies. The significance assessment of the differences between herd characteristics and bacterial isolation was performed using Pearson's chi-squared test. Bacterial isolation occurred in 15.4% (81/526) of the samples from 23.2% (61/263) of the goats. Escherichia coli (45.9% = 28/61), Staphylococcus caprae (16.4% = 10/61) and Enterococcus faecalis (11.5% = 7/61), were the most frequently isolated species. Bacterial isolations were predominant in dairy herds with up to 50 animals, production of 20 to 50 L/day and in the municipality of Porto da Folha. In terms of antimicrobial susceptibility, most isolates demonstrated resistance to penicillin and amoxicillin (88.5%), followed by ceftriaxone (23%), ofloxacin (23%), tetracycline (23%), doxycycline (19.7%), chloramphenicol (11.5%), levofloxacin (11.5%), ampicillin/ sulbactam (8.2%), amikacin (6.6%), cephalothin (4.9%), cephalexin (3.3%) and gentamicin (3.3%). Approximately 20% of the isolates were multidrug resistant, especially E. coli (50%) and S. aureus (16.7%). Discussion: E. coli was the most frequently isolated species from the samples. It is considered an environmental pathogen, and its high frequency in different herds indicates poor milking hygiene. E. coli also stood out as the species presenting the most multidrug-resistant (MDR) isolates (50%), with strains resistant to beta-lactams, aminoglycosides, quinolones, tetracycline, and chloramphenicol. Coagulase-negative staphylococci are recognized as a public health problem as they are etiological agents of various diseases and can easily acquire antimicrobial resistance genes. Although it was not the most frequently isolated species, S. aureus was the species with the second-highest frequency of MDR strains. The presence of MDR species is relevant and indicates the need for urgent action to reduce the dissemination of antimicrobial resistance. Relevant steps must be taken jointly by professionals involved in human, animal, and environmental health.

The objective this study was to evaluate the occurrence of small ruminants seropositive for Brucella abortus in Sergipe, Brazil. Samples of sheep (1,200) and goats (675) serum blood was collected from 101 farms of 25 counties of the three mesoregions of the state. The technique of Acidified Buffered Acid stained with Rose Bengal (RB) was used and all samples confirmed a positive result using the 2-Mercaptoethanol technique. Four (0.21%) seropositive animals were diagnosed by technique AAT stained with RB, three sheep's (0.25%) and a goat (0.15%), were confirmed by the 2ME test. In all the positive properties, the intercropping of small ruminants with cattle was adopted, favoring the contact with the agent. The prevalence of anti-B. abortus antibodies in herds of small ruminants in Sergipe is described for the first time, and is low, however, it is important to identify seropositive animals to be discarded due to their zoonotic potential.(AU)

Foram diagnosticados 4 animais (0,21%) soropositivos pela técnica de AAT corado com RB, 3 ovelhas (0,25%) e 1 cabra (0,15%), que posteriormente foram confirmados pelo teste de 2ME. Em todas as propriedades positivas era adotada a criação consorciada de pequenos ruminantes com bovinos, favorecendo o contato com o agente causador. A ocorrência de anticorpos anti-B. abortus em rebanhos sergipanos de pequenos ruminantes é descrita pela primeira vez, e mostra-se baixa; entretanto, é importante a identificação de animais soropositivos para que sejam descartados, devido seu potencial zoonótico.(AU)

Background: The companion animal market has changed over the years. The number of people living in small apartments has increased; as a result, the demand for small pets such as exotics, fish, and small rodents has also increased due to their smaller space requirements and ease of handling and care. Pets help relieve anxiety and stress in people suffering from social issues. Small rodents are usually bred in specific cages with cellulose or wood shaving bedding, and fed with commercially available diets. Small rodent clinics struggle due to the lack of scientific reports on some diseases and therapies. To date, the oncology literature is too limited to develop better diagnosis and treatment methods. Here, we report three cases of squamous cell carcinoma in the mandibular region of Chinese hamsters (Cricetulus griseus).Case: Three adult male hamsters averaging 1.5 years old, from different pet stores, bred under home conditions by different owners in Sergipe, Brazil, were brought to the Dr. Vicente Borelli Hospital at Pio X University for exotic veterinary care. Each animal had been bred alone in a specific breeding cage. Each had a history of apathy, loss of appetite, and rapid deformity of the facial region. Radiographs showed areas of bone involvement and extensive injury, with partial resorption of the left ramus and angle of the mandibular region. Due to the location of the tumor mass, the clinical status, and limitations in systemic treatment, euthanasia was recommended for each animal. After anamnesis, the animals were subjected to clinical assessment. A firm and well-circumscribed mass was identified on palpation. In case A, it compromised the left mandible from the angle to the body and extended to the maxillary soft tissues and left superior lips. In case B, it extended from the ramus to the symphysis on the left side and to the maxillary region, similar to case A.[...]

As neoplasias em cães e gatos são causas frequentes de morte na Paraíba. Essa dissertação é formada por dois artigos originais: o primeiro, submetido à Pequisa Veterinária Brasileira, relata a frequência de neoplasias diagnosticadas em cães e gatos no Hospital Veterinário da Universidade Federal de Campina Grande, Patos, Brasil, entre 2003 e 2010. Para tal, foram revisados todos os protocolos de necropsias e biópsias realizadas no Laboratório de Patologia Animal da referida instituição. As neoplasias mais frequentes em cães ocorreram na pele e anexo (46,1%), seguido da glândula mamária (24,4%), sistema genital (9,6%) e sistema alimentar (6,9%). Os tumores malignos foram mais frequentes que os benignos (p=0,001), representando 78% e 22% respectivamente. Em gatos, a frequência de neoplasias de pele e glândula mamária foram idênticas (39,4% cada), seguidas das do sistema digestivo (8,5%) e fígado (5,7%); os tumores malignos representaram 95,8% dos tumores diagnosticados nesta espécie. O segundo artigo, aceito para publicação na Veterinary Parasitology, relata a associação da infecção por Platynosomum fastosum com o desenvolvimento de colangiocarcinomas em gatos. P. fastosum é um trematódeo das vias biliares de felinos, geralmente encontrado como achado de necropsia. No início da década de 1980, no Brasil, foi associado à colangiocarcinomas, mas este achado não foi confirmado nas numerosas publicações sobre o parasita nos últimos 30 anos. Durante o período de 2000 a 2011, no Hospital Veterinário da Universidade Federal de Campina Grande, no nordeste do Brasil, foram necropsiados 348 gatos, dos quais 11 (3,16%) apresentaram lesões causadas por P. fastosum e presença do parasito. [...] Além disso, são necessários estudos, que determinem os fatores epidemiológicos envolvidos no desenvolvimento dos tumores que acometem os cães e gatos, nas diferentes regiões, a fim de serem tomadas medidas para diminuir a ocorrência e letalidade das neoplasias.


Neoplasms in dogs and cats are a frequent cause of death in Paraíba. This dissertation is formed by two papers. In the first paper, send for publication to the Brazilian Journal of Veterinary Research reports the frequency of neoplasm diagnosed in dogs and cats at the Veterinary Hospital of the Federal University of Campina Grande in Patos, northeastern Brazil, between 2003 and 2010. All necropsy and biopsy protocols from the pathology laboratory were revised and data related to the tumors were analyzed. Tumors of the skin and anexa were the most frequently diagnosed (46.1%), followed by tumors of the mammary gland (24.4%), genital system (9.6%), and alimentary system (6.9%). Malignant tumors (78%) were more frequent than bening tumors (22%) (p=0.001) In cats the frequency of skin and mammary gland tumors was the same (39.4%), followed by tumors of the digestive system (8.5%) and liver (5.7%). In cats, 95.8% of the tumors were malignant. The second paper, accepted for publication on the veterinary Parasitology reports the association between Platynosomum fastosum infection and cholangiocarcinomas in cats. P. fastosum is a feline biliary tract trematode that generally causes asymptomatic infections. In the early 1980s in Brazil, P. fastosum was associated with cholangiocarcinomas, but this finding was not confirmed in the various publications on the parasite during the last 30 years. From 2000 to 2011, in the Veterinary Hospital of the Federal University of Campina Grande in northeast Brazil, 348 cats were necropsied, 11 of which (3.16%) were parasitized by P. fastosum. [...] As a result, the systematic histologic diagnosis and the determination of the epidemiology of the tumors, in the different regions, are necessary to decrease tumor mortality.
