Objetivou-se identificar as espécies de pulgas e carrapatos de Cerdocyon thous provenientes do estado Pernambuco. Foram examinados 20 animais, estando 30% (6/20) ectoparasitados. Foram coletadas 16 pulgas e 17 carrapatos em cachorros-do-mato de vida livre e de cativeiro no estado de Pernambuco. As pulgas foram identificadas como: Pulex irritans e Ctenocephalides felis; e os carrapatos foram: Rhipicephalus sanguineus sensu lato e Amblyomma ovale. A presença de ectoparasitos de animais domésticos parasitando C. thous, sugere a aproximação de indivíduos desta espécie ao peridomicílio. Além disso, este é o primeiro relato da ocorrência de A. ovale em C. thous no nordeste brasileiro. | This study aimed to identify the species of fleas and ticks of Cerdocyon thous from the state of Pernambuco. Animals (n = 20) were examined, with 30% (6/20) ectoparasitized. Fleas (n = 16) and ticks (n = 17) parasitizing free-living crab-eating fox and captive in state of Pernambuco were collected. The fleas were identified as: Pulex irritans and Ctenocephalides felis; and the ticks were: Rhipicephalus sanguineus sensu lato and Amblyomma ovale. The presence of ectoparasites of domestic animals parasitizing C. thous, suggests a close contact of this species to the peridomicile. Furthermore, this is the first report of the occurrence of A. ovale in C. thous in northeastern Brazil.

O conhecimento do comportamento das artérias que emergem do arco aórtico é importante, pois estas artérias irrigam órgãos vitais encontrados na cabeça, pescoço, cavidade torácica e membros torácicos de animais domésticos e selvagens. Com o objetivo de contribuir com o conhecimento anatômico em gambás e colaborar com a clínica médica e cirúrgica de animais selvagens, descreveu-se neste estudo, a ramescência do arco aórtico em dezoito gambás. Os resultados indicaram que o tronco braquiocefálico e a artéria subclávia esquerda se originaram do arco aórtico em todos os animais estudados. Este padrão de ramescência do arco aórtico é similar ao descrito para a cobaia, chinchila, paca, mão-pelada, nutria, esquilo-vermelho e jaguatirica. O tronco braquiocefálico apresentou como ramos colaterais, a artéria subclávia direita e o tronco bicarotídeo, o qual se bifurcou nas artérias carótidas comuns direita e esquerda (77,7%). O tronco bicarotídeo não apareceu em quatro animais (22,2%). As artérias subclávias direita e esquerda originaram a artéria vertebral, o tronco costocervical e, as artérias torácica interna e cervical superficial. A ramescência encontrada nas artérias subclávias do gambá mostrou similaridades quando comparada com a descrita para outros animais selvagens como a paca, jaguatirica e o mocó. | Knowledge of the aortic arch main and collateral branches is important because these arteries supply vital organs found in the head, neck, thoracic cavity and forelimbs of domestic and wild animals. This study aimed to contribute to the anatomical knowledge in opossums and collaborate with veterinary medical and surgical clinics. Thus, the anatomy of aortic arch was described in eighteen opossums. The results indicated that the aortic arch gives off the brachiocephalic trunk and the left subclavian artery in all animals studied. The branching pattern of the aortic arch is similar to that reported in the guinea pig, chinchilla, paca, raccoon, nutria, red squirrel, and ocelot. The brachiocephalic trunk showed as collateral branches, the right subclavian artery and the bicarotid trunk, that originated in the right and left common carotid arteries (77.7%). Bicarotid trunk was absent in four animals (22.2%). The right and left subclavian arteries originated in the vertebral artery, costocervical trunk, internal thoracic artery, and superficial cervical artery. Collateral branches of the subclavian artery showed similarities to that observed in other wild animals such as paca, ocelot and rock cavy.

Momo, Claudia | Garrido, Eduardo | Werther, Karin
A perdiz (Rhynchotus rufescens) membro da família Tinamidae é uma ave que apresenta relativa facilidade à adaptação ao cativeiro. É considerada apta à produção de carne de boa qualidade, com ótima conversão alimentar. Essas características a torna interessante para produção comercial. Visando conhecer as principais afecções que acometem essas aves, foram analisados achados macro e microscópicos de 114 perdizes que vieram a óbito ao longo de 12 anos, entre 1994 e 2006 provenientes de criatório experimental, mantidas em dois diferentes tipos de recintos. Os exames anatomopatológicos revelaram que os sistemas mais acometidos foram o urinário e o digestório. No primeiro, a gota úrica foi o principal achado, seguida da amiloidose e parasitismo pelo trematoda Paratanaisia confusa. No sistema digestório, foi observada a presença de corpo estranho e parasitismo por Capillaria penidoi em esôfago e inglúvio. As aves mantidas em alojamento com piso natural apresentaram maior parasitismo, enquanto as que foram mantidas em recinto com piso de concreto e palha apresentaram maior quantidade de corpos estranhos no sistema gastrointestinal, caquexia e amiloidose. O objetivo deste trabalho foi descrever os principais achados anatomopatológicos em perdizes criadas em cativeiro, correlacionando-os com o tipo de recinto adotado. | The red-winged tinamou (Rhynchotus rufescens), a bird from the Tinamidae family, can be easily adapted to captivity. It is considered suitable for producing good quality meat while presenting great feed conversion rate, characteristics that make it interesting for commercial production. Therefore, in order to determine the major diseases that affect these birds, 114 birds from two different aviary types that died over a 12-year period, 1994-2006, were analyzed macro- and microscopically. Anatomical and pathological examinations showed that the most frequently affected systems were the urinary and digestive tracts. In the urinary tract, the main finding was gout, followed by amyloidosis and parasitism by the trematode Paratanaisia confusa. In the digestive tract, the presence of foreign material and parasitism by Capillaria penidoi were observed in the esophagus and crop. This study aims to describe the main anatomical and pathological findings in captive-bred red-winged tinamou and correlate them with the aviary type.

Os gambás Sul-americanos são os hospedeiros definitivos de Sarcocystis falcatula, Sarcocystis neurona, Sarcocystis speeri e Sarcocystis lindsayi. Estas espécies de Sarcocystis são morfologicamente similares, mas podem ser distinguidas por sua patogenicidade e infectividade em hospedeiros intermediários (aves e camundongos imunodeficientes) e técnicas moleculares. Os gambás são animais silvestres e sinantrópicos e amplamente distribuídos no território nacional. Estudos anteriores demonstraram uma alta contaminação ambiental com esporocistos de S. neurona em diversas regiões brasileiras. Este artigo revisa informações sobre Sarcocystis spp. excretados por gambás e sua ocorrência no Brasil. | South American opossums are the definitive hosts of Sarcocystis neurona, Sarcocystis falcatula, Sarcocystis speeri and Sarcocystis lindsayi. The sporocysts of these species of Sarcocystis are morphologically similar and methods like infectivity and pathogenicity for intermediate hosts (immunodeficient mice and psittacine birds) and molecular tools are used for identification. Opossums are synanthropic wild animals, and widely distributed in Brazilian territory. Previous studies have shown high environmental contamination with S. neurona sporocysts in several Brazilian regions. This paper reviews information on Sarcocystis spp. shed by various opossum species and its occurrence in Brazil.

Óbitos por infecções causadas por protozoários intestinais são indesejáveis para programas de manejo de fauna, exigidos no âmbito do licenciamento ambiental e que demandam a captura e quarentena de primatas não humanos. Exames coproparasitológicos, necroscópicos, microbiológicos e moleculares foram utilizados para a confirmação do diagnóstico de uma severa enterite necrótica que levou a óbito três fêmeas e dois machos de Alouatta (A.) caraya capturados e mantidos em quarentena prévia à translocação. Exames coproparasitológicos revelaram a presença de cistos de Entamoeba (E.) histolytica/dispar (5/5), Entamoeba (E.) coli (5/5) e Giardia (G.) duodenalis (1/5). A avaliação necroscópica revelou áreas de necrose multifocal severa na mucosa e submucosa intestinal. A análise microscópica revelou a presença de estruturas morfologicamente compatíveis com trofozoítos do gênero Entamoeba spp. em todos os indivíduos examinados. Além disso, G. duodenalis (1/5) foi demonstrada pela técnica de Nested PCR. Sugere-se que quando for necessário o cativeiro temporário de primatas, deverão ser adotados protocolos de manejo adequados buscando a destinação imediata dos animais, de moto a mitigar os efeitos negativos do estresse e reduzir o risco da ocorrência de infecções. | The capture and quarantine of non-human primates could be necessary in some circumstances including those required under environmental permit. Mortality is undesirable for wildlife management programs and could be related to opportunistic pathogens, for example, deaths due to intestinal protozoa infection outbreaks as described here. Parasitological, necroscopic, microbiological, and molecular tests were used in the diagnosis of severe necrotic enteritis leading to death of three female and two male black howler monkeys (Alouatta caraya) captured and held in quarantine prior to translocation. Parasitological tests showed the presence of cysts of Entamoeba histolytica/dispar (5/5), Entamoeba coli (5/5) and Giardia duodenalis (1/5). Necroscopic assessment revealed areas of severe multifocal necrosis in the intestinal mucosa and submucosa. Histopathological examination revealed the presence of structures morphologically compatible to Entamoeba spp. in all individuals examined. Furthermore, G. duodenalis (1/5) was demonstrated by the nested PCR technique. During temporary captivity of non-human primates in management programs, proper handling protocols, including fast or immediate destination, are suggested in order to mitigate the negative effects of stress and decrease the risk of infections.

A tuberculose é uma das doenças mundiais de notificação obrigatória mais importantes causada pelo complexo Mycobacterium tuberculosis que pode infectar pessoas e animais. A morte repentina de um carneiro da Barbária no Zoológico de Curitiba, que apresentou nódulos multifocais no pulmão à necropsia, levantou a suspeita de tuberculose. Foi realizada a Reação em Cadeia da Polimerase Quantitativa (qPCR) de fragmentos de órgãos e fluido. A qPCR detectou a presença do complexo M. tuberculosis nas amostras de pulmão. Este estudo relata a infecção pelo complexo M. tuberculosis no carneiro da Barbária, uma zoonose de grande relevância para a saúde pública, ressaltando-se a necessidade da implementação de medidas de prevenção. Além disso, pode prover um melhor entendimento sobre conservação de espécies, ocorrência e transmissão de doenças em cativeiro, potencial reservatório e impacto na saúde pública para visitantes e funcionários dos zoológicos. | Tuberculosis is one of the most important mandatory notification diseases in the world caused by bacteria of the Mycobacterium tuberculosis complex, infecting both humans and animals. A sudden death of a Barbary sheep in Curitiba Zoo, and presence of multifocal nodules in lungs at necropsy raised suspicion of tuberculosis. Quantitative polymerase chain reaction (qPCR) from organs and fluid was performed and detected M. tuberculosis complex in a lung sample. This research reports the M. tuberculosis complex infection in Barbary sheep, a zoonosis of great relevance to public health and emphasizes the need to implement prevention measures. Furthermore, the research may provide a better understanding for species conservation, occurrence and transmission of diseases in captivity, reservoir potential and public health impact to zoo personnel and visitors.

Objective: The investigation was undertaken to measure the epidemiological features and antimicrobial sensitivity patterns of Escherichia coli among different breeds of goats in Coxs Bazar, Bangladesh.Materials and methods: A total of 150 rectal swab samples were collected from selected goats. The samples were subjected for the isolation of E. coli through a series of conventional bacteriological and biochemical techniques. The isolated E. coli were used for assessing antimicrobial susceptibility by disk diffusion method. Besides prevalence study, nine risk factors were studied; the risk factors were- breed, age, hygienic status, sex, history of recent transportation, season, diarrhea, body condition score, and source of drinking water. Results: The overall prevalence of E. coli in the rectal swabs of goats was 52% (n=78/150). The young goats were highly susceptible (65.0%; n=52/80) to E. coli infection as compared to adults (37.1%; n=26/70). The prevalence was higher (66.7%; n=42/63) in the goats that was reared in poor hygienic condition as compared to the goats that were reared under good hygienic condition. The influence of the source of drinking water on E. coli prevalence was found to be higher both in pond (63.6%; n=7/11) and municipality (61.4%; n=51/83) supplied water as compared to tube-well (35.7%; n=20/56). The goats having recent transportation history showed higher prevalence (64.8%; n=35/54). The prevalence was higher in diarrheic goats (62.0%; n=49/79) than non-diarrheic goats. Among the E. coli isolates (n=78), 31 were found to be multidrug resistant (MDR) to 3 to 8 subclasses of antimicrobials.Conclusion: Presence of MDR E. coli in the studied goats suggest the probable acquisition, development and transmission of MDR E. coli through a number of influencing factors to other animals and potentially to human.http://doi.org/10.5455/javar.2016.c147

Elzlitne, Rabia | Elhafi, Giuma
Objective: The present study was primarily undertaken to determine the seroprevalnace of Chlamidya abortus infection in the Libyan camel (Camelus dromedarius).Materials and methods: Serological tests for C. abortus antibodies were conducted with 245 camels (205 females and 40 males) in different localities in the western region of Libya. Animals varied in age from <1 to 20 years and were sampled randomly from both housed and nomadic herds. From each animal, 10 mL blood sample was collected and sera were separated. Antibodies in the sera against C. abortus were detected using an indirect enzyme-linked immunosorbent assay (ELISA).Results: Results of this study showed that out of the 245 camels tested for anti-chlamydia antibodies, 30 were found positive giving an overall prevalence of 12.25%. The seroprevalence of chlamydiosis was 2 folds higher in females (14.00%) as compared to males (5.00%).Conclusion: The present findings signify the C. abortus as a potential agent to cause abortion in Libyan camel (C. dromedarius). Besides, the persons who handle camels in Libya are at risk of infecting with C. abortus.http://doi.org/10.5455/javar.2016.c151

Objective: This case report describes a clinical case of Johnes disease (JD) in a Friesian calf aging one and half years.Materials and methods: Physical examination of the calf was carried out, history of the farm as well as samples for laboratory examinations were obtained. The laboratory examinations included hematological examinations by direct wet mount, hematocrit centrifugation technique and Giemsa stain, biochemical evaluation of serum, bacterial culture and isolation from feces and aspirate from the swollen jaw. Results: Clinical history showed that the farm had a history of JD, and routine health screening revealed that one of the calves had clinical signs suggestive of Johnes disease. Physical examination of the calf revealed a lumpy jaw, enlarged bilateral pre-scapular and pre-femoral lymph nodes, while hematological and biochemical findings showed a normocytic normochromic anemia, severe leukocytosis with neutropilic left shift and lymphocytosis with hyperproteinemia characterized by hyperglobulinemia. Fecal bacterial tests showed the presence of acid fast bacilli. Based on the history and laboratory findings, the cow was diagnosed with JD. In order to ensure effective control measures, the calf was culled from the heard. Postmortem examination revealed inflamed pre-scapular and pre-femoral lymph nodes with the presence of paramphistomes in the rumen mucosa.Conclusion: Since JD is a chronic disease that lingers in livestock farms, there is need for early identification and culling of infected animal in order to limit its devastation on the farm.http://doi.org/10.5455/javar.2016.c165
