Criptococose respiratória e cutânea em gato de vida livre da cidade de Sobral/CE / Respiratory and cutaneous Cryptococcosis in a free-range cat in the city of Sobral/CE

A criptococose é uma doença infecciosa sistêmica de origem fúngica, causada pelas espécies: Cryptococcus neoformans e Cryptococcus gattii. É considerada uma micose oportunista capaz de infectar mamíferos domésticos, animais silvestres e seres humanos, sendo classificada como uma doença zoonótica. Esse patógeno é encontrado principalmente em ambientes contaminados por fezes de pombos (Columba livia), que atuam como importantes fontes de infecção do fungo. De acordo com sua disseminação para os tecidos do organismo, a doença pode causar diferentes síndromes tanto em seres humanos como em animais síndrome respiratória, síndrome neurológica, síndrome ocular e síndrome cutânea. O diagnóstico pode ser realizado através da pesquisa de antígeno polissacarídeo circulante no soro ou líquor, por meio da prova de látex. Testes imunoenzimáticos (ELISA) também podem ser realizados para detecção de antígenos dessa levedura. Exame citológico, histopatológico e cultura fúngica para a identificação do agente tornam o diagnóstico da criptococose mais fácil. O tratamento é baseado no uso de antifúngicos e sua escolha é realizada através da avaliação dos sinais clínicos observados. Diante do exposto, o objetivo deste trabalho é relatar um caso de criptococose respiratória e cutânea em felino doméstico de vida livre da cidade de Sobral/CE.

Cryptococcosis is a systemic infectious disease of fungal origin caused by the species: Cryptococcus neoformans and Cryptococcus gattii. It is considered an opportunistic mycosis capable of infecting domestic mammals, wild animals, and humans, being classified as a zoonotic disease. This pathogen is mainly found mainly in environments contaminated by pigeon (Columba livia) feces, which act as important sources of fungal infection. According to its spread to the body's tissues, the disease can cause different syndromes in both humans and animals: respiratory syndrome, neurological syndrome, ocular syndrome, and cutaneous syndrome. The diagnosis can be made through the investigation of circulating polysaccharide antigen in serum or cerebrospinal fluid using the latex test. Immunoenzymatic tests (ELISA) can also be performed to detect yeast antigens. Cytological examination, histopathological examination, and fungal culture to identify the agent make the diagnosis of cryptococcosis easier. The treatment is based on the use of antifungals, and its choice is made through the evaluation of the observed clinical signs. In this context, this work aims to report a case of respiratory and cutaneous cryptococcosis in a free-range domestic cat in the city of Sobral/CE.

O Actinobacillus pleuropneumoniae é um patógeno altamente contagioso, que ocasiona hemorragia, pleuropneumonia purulenta e fibrosa. A Pleuropneumonia é amplamente distribuída e gera graves prejuízos para a suinocultura. O Mycoplasma hyopneumoniae ocasionador da pneumonia por micoplasma, doença respiratória crônica. As infecções originadas podem regular negativamente o sistema imunológico do hospedeiro e aumentar a infecção e assim a replicação de outros patógenos. A Pasteurella multocida é o agente causador de uma ampla gama de infecções levando a alto impacto econômico. Patógeno comensal e oportunista da boca, nasofaringe e trato respiratório superior. A identificação precoce e o manejo adequado desses agentes causadores de doenças respiratórias são fundamentais para minimizar a incidência de carcaças suínas. A adoção de medidas preventivas, como a vacinação e práticas de manejo adequadas, pode ajudar a prevenir a propagação dessas doenças e garantir a produção de carne suína segura e de alta qualidade para o consumo humano.(AU)

Respiratory diseases are a significant problem in pork production and can lead to condemnation of carcasses at slaughter. Among the causative agents of these diseases are Actinobacillus pleuropneumoniae, Mycoplasma hyopneumoniae and Pasteurella multocida. Actinobacillus pleuropneumoniae is a highly contagious pathogen that causes hemorrhage, purulent and fibrous pleuropneumonia. Pleuropneumonia is widely distributed and causes serious damage to pig farming. Mycoplasma hyopneumoniae causes mycoplasma pneumonia, a chronic respiratory disease. Originating infections can down-regulate the host's immune system and increase infection and thus replication of other pathogens. Pasteurella multocida is the causative agent of a wide range of infections leading to high economic impact. Commensal and opportunistic pathogen of the mouth, nasopharynx and upper respiratory tract. Early identification and proper management of these agents that cause respiratory diseases are essential to minimize the incidence of swine carcasses. Adopting preventive measures, such as vaccination and proper management practices, can help prevent the spread of these diseases and ensure the production of safe, high-quality pork for human consumption.(AU)

Genomic characterization, antimicrobial resistance profiles, enterotoxin, and biofilm production of methicillin-resistant Staphylococcus aureus isolated from clinical and animal products origins in Eastern Turkey

ABSTRACT: Staphylococcus aureus is an opportunistic and ubiquitous pathogen found in the skin, nares, and mucosal membranes of mammals. Increasing resistance to antimicrobials including methicillin has become an important public concern. One hundred and eight (108) S. aureus strains isolated from a total of 572 clinical and animal products samples, were investigated for their biofilm capability, methicillin resistance, enterotoxin genes, and genetic diversity. Although only one strain isolated from raw retail was found as a strong biofilm producer, the percentage of antimicrobial resistance pattern was relatively higher. 17.59% of S. aureus strains tested in this study were resistant to cefoxitin and identified as methicillin-resistant S. aureus (MRSA) isolates. mecA and mecC harboring S. aureus strains were detected at a rate of 2.79% and 0.93%, respectively. In addition, staphylococcal enterotoxin genes including Sea, Seb, Sec, and Sed genes were found to be 18.5%, 32.4%, 6.5% and 3.7%, respectively. The phylogenetic relationship among the isolates showed relationship between joint calf and cow milk isolates. Multi locus sequence typing (MLST) revealed three different sequence types (STs) including ST84, ST829, and ST6238. These findings highlight the development and spread of MRSA strains with zoonotic potential in animals and the food chain throughout the world.

RESUMO: Staphylococcus aureus é um patógeno dúctil e ubíquo encontrado na pele, narinas e membranas mucosas de mamíferos. O aumento da resistência aos antimicrobianos, incluindo a meticilina, tornou-se uma importante preocupação pública. Cento e oito (108) cepas de S. aureus isoladas de um total de 572 amostras clínicas e de produtos animais foram investigadas por sua capacidade de biofilme, resistência à meticilina, genes de enterotoxinas e diversidade genética. Embora apenas uma cepa isolada do cru tenha sido encontrada como forte produtora de biofilme, a porcentagem do padrão de resistência antimicrobiana foi relativamente maior. Parte das cepas (17,59%) de S. aureus testadas neste estudo eram resistentes à cefoxitina e identificadas como isolados de MRSA. mecA e mecC abrigando cepas de S. aureus foram detectados a uma taxa de 2,79% e 0,93%, respectivamente. Além disso, verificou-se que os genes da enterotoxina estafilocócica, incluindo os genes Sea, Seb, Sec e Sed, eram 18,5%, 32,4%, 6,5% e 3,7%, respectivamente. A relação filogenética entre os isolados mostrou relação entre os isolados de bezerro e leite de vaca. A tipagem de sequência multiloco (MLST) revelou três tipos de sequência diferentes (STs), incluindo ST84, ST829 e ST6238. Essas descobertas destacam o desenvolvimento e a disseminação de cepas de MRSA com potencial zoonótico em animais e na cadeia alimentar em todo o mundo.

Atypical mandibular osteomyelitis in an ewe caused by coinfection of Pseudomonas aeruginosa and Lactococcus raffinolactis

Background: Osteomyelitis is defined as a bone inflammation involving the cortical and medullary regions, usually caused by the local invasion of opportunistic microorganisms. The inflammatory reaction of bone may extend to the periosteum and soft tissues, compromising adjacent structures far from the initially infected foci. Different classifications of transmission routes, gravity levels, and tissues involved in animal and human osteomyelitis are available. In humans, the infection can reach bone tissue by exogenous or hematogenous pathways. This paper reports an atypical case of mandibular pyogranulomatous osteomyelitis in an ewe caused by concomitant Pseudomonas aeruginosa and Lactococcus raffinolactis infection. Case: The animal presented a 1-month history of progressive mandibular enlargement refractory to conventional therapy. In a physical examination, an increased volume located in the ventrolateral region of the right ramus of the mandible was observed. Fine-needle aspiration of the lesion enabled isolation in bacteriological culture of Pseudomonas aeruginosa and Lactococcus raffinolactis using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDITOF MS). Besides support care procedures and antimicrobial treatment approaches for the sheep based on in vitro tests, the animal died due to the severity of the clinical signs and the progressive worsening of the general health status. The radiographic image examination of the mandibular region revealed a severe and infiltrative periodontal reaction, with a predominance of a great number of neutrophils and macrophages, necrotic areas, and bone destruction, characterized histologically as a pyogranulomatous rection. At post mortem examination, a large pyogranuloma was observed in the entire horizontal branch of the mandible as well, showing a dark yellowish content of coarse consistency, caseous appearance, and bone fragmentation. Discussion: Ovine mandibular osteomyelitis is a well-established bone inflammation involving the cortical and medullary regions, characterized clinically by local enlargement, asymmetry, pain sensitivity, edema, hyperthermia, infiltrate caseous or suppurative material, and bone rarefaction. In the current report, 1-month history of progressive enlargement of the mandibular region, prostration, and weight loss in an ewe were referred. Where clinical and epidemiological features, bacteriological, cytological, histological, and mass spectrometry diagnostic approaches were assessed to diagnostic. Most reports involving the etiology of ovine mandibular osteomyelitis have been diagnosed based on classical phenotypic tests. Here, the concomitant identification of P. aeruginosa and L. raffinolactis infection was possible using mass spectrometry (MALDI-TOF), highlighting the importance of molecular methods in the diagnosis of animal diseases. In addition, the differentiation between Lactococcus and Enterococcus species is difficult, which could underestimate the diagnosis of Lactococcus species as a primary pathogen from animal diseases. We report, for the first time, a fatal case of mandibular pyogranulomatous osteomyelitis in a sheep caused by Pseudomonas aeruginosa and Lactococcus raffinolactis coinfection.

Presença de Mollicutes e Mycoplasma bovis em swabs nasais de bezerros e na secreção mastítica de vacas / Presence of Mollicutes and Mycoplasma bovis in nasal swabs from calves and in mastitic secretion from cows / Presencia de Mollicutes e Mycoplasma bovis en hisopos nasalses de terneros y secrecion de mastitis de vacas

Mycoplasma bovis faz parte da microbiota do trato respiratório bovino, mas é considerado um patógeno oportunista de extrema importância nas doenças respiratórias de bezerros. Causa ao rebanho diversas doenças como mastite, poliartrite, pneumonia e endometrite. Esse patógeno é altamente contagioso e os animais com mastite são potenciais disseminadores da infecção para o rebanho, pois liberam de 106a 108UFC por mL de leite. Da mesma forma, animais com pneumonia eliminam, por meio de secreções respiratórias, altas cargas microbianas do agente. O presente estudo teve como objetivo realizar a detecção molecular de Mycoplasma bovis em 185 amostras de secreção mastítica de vacas, bem como em 50 amostras de swab nasal de bezerros saudáveis com ou sem sinais de pneumonia e nascidos de vacas com mastite, pertencentes a quatro fazendas leiteiras do estado do Paraná, onde foram diagnosticados casos de mastite. A extração do DNA de ambas as secreções foi realizada pelo método de termólise. Para a reação em cadeia da polimerase (PCR), primers genéricos foram empregados para amplificar o DNA dos Mollicutes e as amostras positivas foram submetidas à PCR com primers específicos para M. bovis. A positividade para M. bovis foi de 3,78% nas amostras de secreção mastítica, independente da fazenda, e de 20% nos swabs nasais.

Mycoplasma bovis is part of the bovine respiratory tract microbiota but is considered an opportunistic pathogen of extreme importance in respiratory diseases of calves. It causes to the herd several diseases such as mastitis, polyarthritis, pneumonia and endometritis. This pathogen is highly contagious and animals with mastitis are potential disseminators of infection to the herd since they release from 106 to 108CFU per mL milk. Similarly, animals with pneumonia eliminate, through respiratory secretions, high microbial loads of the agent. The present study aimed to perform molecular detection of Mycoplasma bovis in 185 milk samples from cows with clinical mastitis, as well as in 50 nasal swab samples from healthy calves with or without signs of pneumonia and born from cows with mastitis, all belonging to four dairy farms in Paraná State, where cases of mastitis had been diagnosed. DNA extraction from both secretions was carried out according to the thermolysis method. For polymerase chain reaction (PCR), generic primers were employed to amplify the Mollicutes DNA and positive samples were subjected to PCR with primers specific for M. bovis. Positivity for M. bovis was 3.78% in mastitic samples, regardless of the farm, and 20% in nasal swabs.

Background: Staphylococcus pseudintermedius is an opportunistic pathogen, belonging to the genus Staphylococcus.The methicillin-resistant Staphylococci have the mecA-gene, which confers them with the ability of becoming resistant tomethicillin and multiple classes of antimicrobials, which makes the treatment of the affections caused by these specimensdifficult. This work describes a case of systemic infection and death by methicillin-resistant S. pseudintermedius, in a canine.Case: A crossbred bitch (Canis lupus familiaris), was admitted to the University Veterinary Hospital of the Federal Universityof Western Bahia (HVU-UFOB). The main complaint reported by the owner was the presence of mammary nodules andconstant nasal secretion. During the clinical examination was observed reactivity in the popliteal and left submandibularlymph nodes, pale mucous membranes, stomatitis, bilateral mucopurulent nasal secretion, abdominal pustules, serous secretion in the inguinal mammary gland and focal alopecia on the dorsum. On auscultation, was identified only arrhythmiaand the other physiological parameters of the animal were within normality for the species. Samples of the nasal secretionand of the secretion from the abdominal pustules were collected, and sent to the Veterinary Microbiology Laboratory ofthe same institution. The samples collected were sown in 5% Blood Agar (BA), Sabouraud Agar (SAB) and MacConkeyAgar (MCK), after 24 h was observed in BA the growth of macroscopically white colonies, with a humid aspect, creamyconsistency, with presence of catalase and α-hemolysis. Microscopically, was observed the presence of Gram-positivecocci, suggestive of Staphylococcus sp. Microscopically, was observed the presence of Gram-positive cocci, suggestiveof Staphylococcus sp. In the MALDI-TOF mass spectrometry, was identified S. pseudintermedius. Enrofloxacin [Enrotrat...(AU)

Glossite por Actinobacillus equuli subsp. equuli em um equino / Glossitis by Actinobacillus equuli subsp. equuli in an equine

Background: Actinobacillosis in adult horses is rare, and is often associated with infection due to Actinobacillus equulisubsp. equuli, which is a commensal organism inhabiting the oral cavity of healthy animals. It is an opportunistic pathogen,and the infection usually occurs secondary to another primary disease or due to predisposing factors such as pre-existinglesions, mainly in the oral cavity. Infection may be associated with peritonitis, bacterial endocarditis, pneumonia, enteritis,infectious periorchitis, abortion, and septicemia. This paper aims to describe the clinical, microbiological, and pathologicalaspects of actinobacillosis in the oral cavity of a horse.Case: A case of actinobacillosis has been reported in a 22-year-old gelding Quarter Horse. According to the owner, theanimal presented with progressive weight loss during the previous three months, and leakage of food from the oral cavity.Examination of the oral cavity revealed sharp enamel overgrowths, which had been corrected during a previous dentalprocedure. However, five days after the procedure, the animal developed halitosis. Ceftiofur sodium (4.4 mg/kg intramuscularly, every 24 h) was prescribed; two days after the commencement of antimicrobial therapy, the animal presented withsialorrhea, bilateral submandibular lymphadenomegaly, protrusion of the tongue, edema of the base of the tongue, cheeks,and gums, in addition to black-colored sores and scales in the oral mucosa, particularly affecting the base of the tongue andgums. Samples from ulcerative lesions found at the base of the tongue and gums were collected using sterile swabs, andculture and antibiogram were requested. Microbiological culture led to the growth of small colonies measuring less than5 mm in diameter, that were non-hemolytic, slightly whitish in color but non-opaque, smooth and bright in appearance.These were identified as gram-negative rods on microscopy, and further characterized...

Health State, morphological characterization and biometric parameters in the mangrove crab Ucides cordatus Linnaeus, 1763 (Brachyura: Ocypodidae)

The crab Ucides cordatus is an important feature of mangroves in the North and Northeast of Brazil. In 2002 a large mortality was reported on this species in the Jaguaribe River Estuary. In order to investigate the possible causes specimens were collected monthly between May 2002 and December 2003 at five sites: Fortim (E1), Fortim (E2), Cumbe (E3) Aracati (E4) and Guajiru (E5). The mangrove structure and environmental parameters (salinity, pH, temperature and DO) were also evaluated. Water was collected for suspended solids analysis, BOD and nutrient levels. Salinity decreased in the rainy season, with no significant variation of pH and temperature. Dissolved oxygen levels had a mean of 5.7 mg L-1. Suspended solids increased at site E4, with BOD varying at E1 and E2 during the dry season. The same was observed at sites E1, E2 and E3 during the rainy season. Ammonia levels at E1 and E2 and phosphorus in all seasons, increased with rain events. Four lines of investigation were adopted: biometry, histology, hematology, and bioassay. There was no significant difference between animals in biometrics and histology showed no cellular alterations. However, hematology showed a significant difference between the E1 and E3 sites due to depletion in the number of hemocytes in E1, probably in response to environmental impacts. This can lead to poor immunity, leading to opportunistic pathogen infections such as viruses, bacteria and fungi. The bioassay showing no abnormal behavior or mortality. The structure the of mangrove was developed in all areas, except in E5 which served as a control site, with significant environmental stress with high levels of herbivorous growth (> 50%) and a salinity of around 50 ‰. It is believed that the mortality of the crabs was an occasional occurrence, probably due to toxin production by some fungal organism.

Isosporose canina: uma abordagem clínica neonatal / Isosporose canina: uma abordagem clínica neonatal

Acute diarrhea in young dogs is among the main complaints described by tutors in veterinary services. Complications related to water and electrolyte imbalances due to intestinal alterations can compromise homeostasis in these pups, mainly due to dehydration. Consequently, they do not present a satisfactory clinical response and are exposed to the risk of early death. Among the different types of diarrhea, the infectious diarrhea due to viruses, bacteria, and parasites are particularly significant. Coccidia of the genus Isospora (Cystoisospora spp.) is an important intestinal pathogen that causes severe clinical manifestations in puppies. Since high parasitic loads render these puppies highly susceptible to opportunistic infections, coccidia infection may cause impaired corporal and cognitive development and even lead to death. Studies regarding this issue, particularly concerning clinical knowledge in neonatology, are scarce in veterinary medicine. Thus, in this study, we intend to discuss the enteric alterations and the most commonly used current diagnostic techniques, as well as to analyze effective therapeutic and prophylactic proposals.

As diarreias agudas em cães jovens estão entre as principais queixas descritas pelos tutores nos serviços veterinários. As complicações relacionadas aos desequilíbrios hídrico e eletrolítico decorrentes das alterações intestinais comprometem a homeostase destes filhotes, principalmente devido a desidratação, não apresentam resposta clínica satisfatória e ficam expostos ao risco de morte precoce. Dentre os diferentes tipos de diarreia, sobressaem as de origem infecciosa. Os agentes podem ser vírus, bactérias, fungos e parasitos. Entre estes últimos agentes, os coccídios do Gênero Isospora (Cystoisospora spp.) se destacam como patógenos intestinais que ocasionam manifestações clínicas graves em filhotes, pois elevadas cargas parasitárias propiciam condição de maior susceptibilidade à infecções oportunistas, podendo também prejudicar o desenvolvimento corporal e cognitivo e/ou até mesmo levar a morte do cão. Diante de tal temática, na medicina veterinária os estudos são escassos, principalmente quanto ao conhecimento clínico em neonatologia de tal modo tencionamos discutir a respeito das alterações entéricas, métodos de diagnóstico mais utilizados e atuais, bem como analisar as propostas terapêuticas e profiláticas efetivas.

Diagnóstico de Malassezia pachydermatis por cultura fúngica de amostra de pelos e escamas de um cachorro-do-mato / Diagnosis of Malassezia pachydermatis by fungal culture of sample of hair and scales of a puppy

A Malassezia pachydermatis é um fungo oportunista amplamente relatado em carnívoros domésticos, mas que possui uma escassez de estudos e relatos quando se analisam os canídeos e felídeos selvagens, apesar de que hoje já se sabe que este fungo representa um potencial patógeno em quadros de otites e dermatites fúngicas nesses animais. Faz-se então, como objetivo do presente trabalho, relatar um diagnóstico de Malassezia pachydermatis em amostra de pelos e escamas de um Cachorro-do-mato (Cerdocyon thous) por meio do diagnóstico micológico, o qual incluiu exame direto, por análise microscópica da amostra clínica e cultura fúngica em àgar sabouraud simples e àgar sabouraud acrescido de cloranfenicol e cicloheximida.

Malassezia pachydermatis is an opportunistic fungus widely reported in domestic carnivores but has a shortage of studies and reports when canids and wild felids are analyzed, although it is now known that this fungus represents a potential pathogen in otitis and fungal dermatitis in these animals. The objective of this work is to report a diagnosis of Malassezia pachydermatis in a sample of hairs and scales of a Cerrado (Cerdocyon thous), using a mycological diagnosis, which included a direct examination by microscopic analysis of clinical sample and fungal culture on simple sabouraud agar plus saber agar plus chloramphenicol and cycloheximide.

Sobrevivência e desenvolvimento de Pseudomonas aeruginosa em água mineral experimentalmente contaminada / Survival and growth of Pseudomonas aeruginosa in experimentally contaminated mineral water

Pseudomonas aeruginosa, agente patogênico oportunista, é frequentemente encontrado em águas minerais e pode causar infecções em indivíduos imunocomprometidos. Neste estudo foi avaliada a sobrevivência e/ou a multiplicação de P. aeruginosa em amostras de água mineral em embalagens plásticas de 1,5 L e 20 L, experimentalmente contaminadas, armazenadas a 35 ± 1ºC, 4 ± 2°C e em temperatura ambiente (20-25ºC), durante o período de validade do produto. Nas amostras de água mineral em garrafa plástica de 1,5 L, armazenadas a 35 ± 1ºC e 4 ± 2ºC, a população de P. aeruginosa manteve-se viável durante 370 e 100 dias, respectivamente. O maior aumento da população bacteriana ocorreu nas amostras de água mineral em galão de 20 L, armazenadas entre 20 a 25ºC, que passou de 3,8 para 6,6 log10 UFC/mL em um período de sete dias. Portanto, os galões de 20 L merecem atenção especial, pois além de serem retornáveis, normalmente são armazenados à temperatura ambiente. Os resultados reforçam a necessidade das empresas de águas minerais implantarem e implementarem as Boas Práticas de Fabricação (BPF) e o sistema Análise de Perigo e Pontos Críticos de Controle (APPCC) para eliminar ou minimizar os riscos do consumo deste produto.

Pseudomonas aeruginosa, an opportunistic pathogen, is often found in bottled waters and capable of infecting the immunocompromised patients. The present study aimed at evaluating the survival and/ or the growth of P. aeruginosa strain in 1,5 L and 20 L bottled mineral water samples experimentally contaminated, stored at 35 ± 1°C, 4 ± 2°C, and at room temperature (from 20 to 25°C) during the product shelf-life period. In the mineral water samples contained in 1.5 L bottles, stored at 35 ± 1ºC and 4 ± 2ºC, P. aeruginosa remained viable for 370 and 100 days, respectively. The major increase in the bacterial population occurred in mineral water samples in 20 L bottles stored at 20 to 25ºC, being from 3.8 to 6.6 log10 CFU/mL, in a period of seven days. Therefore, the 20 L bottles deserve a special attention because, in addition of being returnable, they are usually stored at room temperature. The results reinforce the need of the mineral water companies in implementing the Good Manufacturing Practice (GMP) and the HACCP (Hazard Analysis Critical Control Point) to eliminate and to minimize the risks of consuming the contaminated product.

Occurrence of zoonotic Enterocytozoon bieneusi in cats in Brazil / Ocorrência de Enterocytozoon bieneusi zoonótico em gatos no Brasil

Enterocytozoon bieneusi is an opportunistic intestinal pathogen that infects humans and a wide variety of animals worldwide. Our aim in this study was to investigate the occurrence of E. bieneusi in a domestic cat population in Campo Grande, Mato Grosso do Sul, Brazil. Sixty fecal samples from diarrheic cats were subjected to polymerase chain reaction (PCR) and the amplicons were sequenced for identification. E. bieneusi was detected in two samples (3.3%), both identified as genotype D. This genotype has already been reported in animals and humans and is considered a zoonotic genotype. Our findings represent the first report of E. bieneusi in domestic cats in Brazil, reinforcing the importance of identifying this agent as a source of infection in animals and humans.(AU)
