Bilateral typical complete colobomas in a donkey: retinographic and fluorangiographic description.

An 18-year-old male donkey was referred with a history of blindness. On ocular examination a complete bilateral typical colobomatous defect involving iris, ciliary body, lens, choroid, retina and optic nerve was observed. An optic pit was presented at the temporal side of the right optic head. Ophthalmoscopic and fluorangiographic characteristics are described.

Cytogenetic monitoring of domestic mammals exposed to wastewaters from the localities of Dladla and Boukallou near Settat, Morocco.

The aim of this work was to know the biological impact of wastewaters on livestock in the localities of Dladla and Boukallou (Town of Settat, Morocco), where wastewaters are largely used by the local population for their agricultural activities. We used the micronucleus (MN) test in cytochalasin B blocked binucleated cells (BNC) to assess the possible induced genetic effects. The cellular proliferation index (PI) was also calculated. Blood samples were collected from sheep, bovines and mules and peripheral blood cultures were made according to our laboratories' standard methodology. The results showed a significant increase of micronucleated cells in the lymphocytes of the exposed animals (14+/-8.79 MN/500 BNC) compared to the control (3+/-1.54 MN/500 BNC). The PI showed a nonsignificant decrease in the exposed animals. The highest MN frequency was found in mules which is probably due to their more sedentary life. Direct use of the wastewater by the animals as their source of drinking water significantly increased the frequency of cells with micronuclei. We also established an inverse correlation between the chromosome number and the PI. These results suggest a serious degradation of the ecosystem due to the wastewaters with a direct impact on its inhabitants.

Patent ductus arteriosus in a 9-day-old Grant's zebra.

A 9-day old Grant's zebra with a 3-day history of lethargy, weight loss, inappetance, and diarrhea was treated with ampicillin, vitamin E and selenium, and tetanus antitoxin without effect in 24 h. On transfer to the local veterinary clinic, a grade IV/VI continuous heart murmur was detected and a patent ductus arteriosus found at necropsy.

Patent urachus with subsequent joint infection in a free-living Grevy's zebra foal.

A free-living, female Grevy's zebra (Equus grevyi) foal was found lethargic, lame, with swollen joints, pyrexia, and urine dripping from the umbilicus. It died 2 days later despite intensive care. Gross examination revealed patent urachus and suppurative arthritis. Swabs were taken from the joints, the patent urachus, and urine for bacteriology. The dominant isolate was Escherichia coli. The joint infection was probably secondary to septicemia, resulting from the patent urachus. To our knowledge, this is the first report of neonatal patent urachus in a wild equid.

Resposta inflamatória peritoneal de asininos (Equus asinus) submetidos à ovariectomia por laparotomia e laparoscopia / Peritoneal inflammatory response of the donkeys (Equus asinus) submitted ovariectomy by laparotomy and laparoscopy

Objetivou-se avaliar resposta inflamatória e concentrações de proteínas em líquido peritonealde asininas submetidas à ovariectomia por laparotomia e laparoscopia. Foram utilizadas 18 fêmeas adultas, pesando em média 100kg, as quais foram divididas em dois grupos, de nove animais cada: o grupo I, em que foram ovariectomizadas por laparotomia, e o grupo II por laparoscopia. Após as cirurgias, em ambos os grupos foram avaliadas as seguintes variáveis no líquido peritoneal: pH, densidade, número de hemácias, leucócitos e proteínas de fase aguda (fibrinogênio, haptoglobina, albumina, antitripsina, alfa-1 glicoproteína ácida, ceruloplasmina, transferrina, imunoglobulinas A e G). Todas as variáveis foram analisadas antes das cirurgias, 12, 24, 48, 72 horas, oito e 16 dias após os procedimentos cirúrgicos. O número de hemácias e leucócitos aumentou 24 horas depois das cirurgias nos dois grupos. Haptoglobina, alfa-1 glicoproteína ácida,albumina, transferrina, gamaglobulinas A, G e proteínas totais aumentaram nos dois grupos. As concentrações de ceruloplasmina não variaram enquanto a antitripsina não foi detectada no líquido peritoneal de asininos.Foi identificada uma proteína com23.000kD, que não tem denominação nem descrição no líquido peritoneal de asininos.(AU)

The aim of this study was to evaluate the inflammatory response and protein concentrations in the peritoneal fluid of donkeys submitted to laparotomy and laparoscopic ovariectomy. Eighteen adult females, weighing on average 100kg, were divided into two groups, of 09 animals each, where in group I, they were ovariectomized by laparotomy and group II by laparoscopy. Following the surgeries, the following variables were evaluated in the peritoneal fluid: pH, density, number of red cells, leukocytes and acute phase proteins (fibrinogen, haptoglobin, albumin, antitrypsin, alpha-1 acid glycoprotein, ceruloplasmin, transferrin, Immunoglobulins A and G). All variables were analyzed before the surgeries, 12, 24, 48, 72 hours, 8 and 16 days after the surgical procedures. The number of red cells and leukocytes increased 24 hours after the surgeries in both groups. Haptoglobin, alpha-1 acid glycoprotein, albumin, transferrin, gammaglobulins A and G, and total proteins increased in both groups. Concentrations of ceruloplasmin did not change while antitrypsin was not detected in the asinine peritoneal fluid. A protein of 23,000kD, which has no name or description in the peritoneal liquid of donkeys, has been identified.(AU)

Fungi in the respiratory tract of horses with recurrent airway obstruction / Presença de fungos no trato respiratório de equinos e sua associação com obstrução recorrente das vias aéreas

This study aims to compare the concentration of viable fungi, especially those of the genus Aspergillus in the respiratory tract of stabled horses with and without Recurrent Airway Obstruction (RAO). Thirty two housed horses from four equestrian centers in Brazil were included in the study. These animals were submitted to clinical examination and to a respiratory sample collection. They were categorized into two groups: healthy and RAO-affected horses. Samples obtained by tracheobronchial washes were evaluated for fungal microscopy, quantitative culture and Aspergillus spp. quantification. Eighteen healthy and 14 RAO-affected horses were studied. Fungi were more frequently recovered in the RAO group, in comparison to controls, for both fungal microscopy (P<0.0001), fungal culture (P<0.0001) and Aspergillus spp. quantitative culture (p=0.001). In conclusion, horses with RAO have significantly higher fungal load in the respiratory tract in comparison to healthy horses. The implications of these findings in terms of the pathogenesis of RAO deserve additional investigation...

Este estudo objetivou comparar a concentração de fungos viáveis, especialmente do gênero Aspergillus, no trato respiratório de equinos estabulados com e sem obstrução recorrente das vias aéreas (ORVA). Trinta e dois equinos provenientes de quatro centros de treinamento equestre do Brasil foram incluídos no estudo. Os animais foram submetidos a exame clínico e coleta de amostra respiratória, sendo categorizados em dois grupos: sadios e ORVA. Os lavados traqueobrônquicos obtidos foram avaliados por exame micológico direto e cultivo quantitativo. Ao todo, 18 equinos saudáveis e 14 com ORVA foram estudados. Fungos foram mais frequentemente detectados em amostras do grupo ORVA em comparação com o grupo controle, tanto no exame micológico direto (P<0,0001) e cultivo quantitativo (P<0,0001) quanto na concentração de unidades formadoras de colônias (UFC) de Aspergillus spp. isolada em cultivo (p=0,001). Equinos com ORVA têm maior concentração de propágulos fúngicos no trato respiratório em comparação com animais sadios. As implicações desses achados na patogenia da ORVA merecem maior atenção e investigação...

Doenças de asininos e muares no semiárido brasileiro / Diseases of donkeys and mules in the Brazilian semiarid

The diseases of donkeys and mules in the semiarid region of northeastern Brazil were evaluated in a retrospective study of 200 donkeys and 58 mules, in the Veterinary Hospital of Federal University of Campina Grande, from January 2002 to December 2012. Data records of these animals as identification, anamnesis, clinical examination, treatment protocol, and outcome of cases were collected. The affected systems in order of frequency of cases were: integument, 88 cases; musculoskeletal, 78; digestive, 36; nervous, 23; reproductive, 15; and respiratory, 6. Eight animals were examined before orquiectomy; three animals had inconclusive diagnosis and one animal suffered a bee attack. The main diseases diagnosed in donkeys were traumatic wounds (32/200), fractures (27/200) and colic (14/200). In mules the main diagnoses were colic (8/58) and traumatic wounds (6/58). Fractures were the main motivation for performing euthanasia (22/200 donkeys and 3/58 mules). It is concluded that most diagnosed diseases are associated with mistreatment or lack of attention to the animals and should be prevented through awareness and education campaigns of owners and handlers.

As doenças de asininos e muares na região semiárida do nordeste do Brasil foram avaliadas em um estudo retrospectivo dos 258 atendimentos realizados no Hospital Veterinário da Universidade Federal de Campina Grande no período de janeiro de 2002 a dezembro de 2012. Dos prontuários desses animais foram coletados dados referentes a identificação, anamnese, exame clínico, diagnóstico, protocolo de tratamento e evolução dos casos. Durante o período analisado foram atendidos 200 asininos e 58 muares. Os sistemas afetados foram os seguintes em ordem de frequência: tegumentar, 88 casos; musculoesquelético, 78; digestivo, 36; nervoso, 23; reprodutor, 15; e respiratório, 6. Oito animais foram atendidos para avaliação pré-cirúrgica e encaminhados para orquiectomia; três animais tiveram diagnóstico inconclusivo e um animal sofreu acidente por picada de abelha. As principais enfermidades diagnosticadas nos asininos foram feridas traumáticas (33/200), fraturas (27/200) e cólica (14/200). Para os muares os principais diagnósticos foram cólica (8/58) e feridas traumáticas (6/58). Em ambas as espécies as fraturas foram a principal causa para realização de eutanásia (22/200 asininos e 3/58 muares). Conclui-se que a maioria das doenças diagnosticadas estão associadas com maus tratos ou falta de atenção com os animais e devem ser prevenidas mediante campanhas de conscientização e educação dos proprietários e tratadores, esclarecendo sobre a importância das melhorias do manejo e do bem-estar dos animais.
