RESUMO

Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia. Treatment for arthritis was initiated, and the animal showed a slight improvement in limb function. However, 21 days after hospitalization, due to a comminuted fracture of the tibia, it was euthanized. At necropsy, yellowish masses were found from the metatarsal to the tibia, and around the tarsal bones and joint. Similar masses were also found in the left kidney. Numerous nematodes compatible with H. gingivalis were identified. This is the first description of a pathological fracture caused by H. gingivalis infection in an equine limb.

RESUMO

Samples of pregnant uterus of 71 zebu cows were collected in a slaughterhouse. The fetuses were divided into three gestational stages: initial stage until 90 days (T1), an intermediate stage from 91 to 180 days (T2) and the fi nal stage after 181 days (T3) and the descriptive statistical analysis of the data was used SPSS Statistics 17.0. The volumes of the fetal fl uids have increased during the pregnancy, with T1 and T3 the volume of allantoic liquid was higher, was not the case in T2. Every stage of pregnancy was increased by an average of 20 placentomes and 1318.5g in weight of the uterus and pregnancy presented with greater frequency in the right horn. (AU)

Foram coletadas em frigoríficos 71 amostras de úteros gravídicos de vacas aneloradas. Os fetos foram distribuídos em três fases gestacionais: fase inicial até 90 dias (T1), fase intermediária de 91 a 180 dias (T2) e a fase final após 181 dias (T3) e para a análise estatística descritiva dos dados foi utilizado o programa SPSS Statistics 17.0. Os volumes dos líquidos fetais aumentaram no decorrer da gestação, sendo que em T1 e T3 o volume do líquido alantóide foi maior, não ocorrendo o mesmo em T2. A cada terço gestacional houve um aumento, em média, de 20 placentônios e de 1318,5 g no peso do útero e a gestação apresentou-se com maior frequência no corno direito.(AU)

RESUMO

A brucelose é uma doença infecto-contagiosa provocada por bactérias do gênero Brucella. Brucella abortus é a espécie responsável pela maioria das infecções em bovinos e bubalinos, nos quais, está associado principalmente com problemas reprodutivos, o que gera grandes prejuízos econômicos. Além disto, pelo fato de possuir caráter zoonótico, gera também preocupações no âmbito da saúde pública. Desconhecem-se a prevalência real e a distribuição desta enfermidade nos rebanhos do Rio Grande do Norte, informações relevantes para que se possam adotar as devidas medidas de controle e prevenção. Objetivou-se no presente trabalho determinar a frequência e a distribuição da brucelose em bovídeos no Estado do Rio Grande do Norte, nos anos de 2008 e 2009. Foram utilizados os informes mensais sobre a ocorrência e o diagnóstico de brucelose, enviados pelas Unidades Locais de Saúde Animal e Vegetal para a sede do Instituto de Defesa e Inspeção Agropecuária do Rio Grande do Norte. As frequências de focos e de animais infectados no Estado, no ano de 2008, foram de 3,99% e 1,86%, respectivamente. No ano de 2009 essas frequências foram de 3,47% e 2,62%, respectivamente, demonstran- do que a brucelose está presente e com frequências variadas na maior parte das regiões do Rio Grande do Norte.(AU)

Brucellosis is an infectious disease caused by the bacteria Brucella sp.. Brucella abortus is the species responsible for most of the infections in cattle and buffaloes, which is mainly associated with reproductive disturbances, which causes great economic losses. Moreover, as a zoonosis, it is also a public health concern. The prevalence and distribution of this disease in flocks of Rio Grande do Norte are unknown. This information is relevant to control and prevent disease in the State. The aim of this study was verify the frequency and distribution of brucellosis in cattle from Rio Grande do Norte between 2008 and 2009. We adopted the database of the occurrence and diagnosis of brucellosis employed by the Local Units for Animal and Plant Health, which were reported to the headquarters of the Institute for Agropecuary Defense and Inspection of Rio Grande do Norte. The frequency of outbreaks and infected animals in the state were 3.99% and 1.86%, respectively in 2008, and 3.47% and 2.62%, respectively in 2009. The study showed that brucellosis is present and with variable frequency in most regions of Rio Grande do Norte.(AU)

RESUMO

This paper reports the first case of coenurosis in the State of Mato Grosso do Sul, Brazil. This disease is caused by the larval stage of the tapeworm Taenia multiceps (Leske, 1780). The animal in which the disease was diagnosed was an 18-month-old ewe from an endemic area of Southern Brazil as an imported animal among a group of 30 sheep. The clinic-pathological condition was that commonly found in herbivores affected by the disease, especially sheep. Apathy, nystagmus, intermittent blindness, circling and pressing head against obstacles were the neurological signs reported. The necropsy showed that a brain lesion in the subcortex of the right hemisphere was a bladder-like cyst measuring 4 cm in diameter filled with a translucent fluid with a large number of white spherules (protoscolices) floating. In addition to the identification of the Coenurus cerebralis protoscolices, the brain tissue lesion was histopathologically described.

Este trabalho relata o primeiro caso de cenurose no Estado de Mato Grosso do Sul, Brasil. Essa doença é causada por estágios larvais de Taenia multiceps (Leske, 1780). O animal no qual foi diagnosticado, tinha cerca de 18 meses de idade, oriundo de uma área endêmica no Sul do Brasil, integrante de um grupo de 30 ovinos importados para o Estado de Mato Grosso do Sul. O quadro clínico-patológico apresentado é aquele comumente descrito para herbívoros, infectados com o agente, especialmente ovinos. Os sinais clínicos relatados foram: apatia, nistagmo, cegueira intermitente, andar em círculos e pressão da cabeça contra obstáculos. Na necropsia foi observada uma lesão, no subcórtex do hemisfério cerebral direito, caracterizada por um cisto em forma de vesícula, medindo 4 cm de diâmetro, e seu interior preenchido por líquido translúcido com grande número de pequenas esferas brancas, identificadas como protoscolices. Os protoscolices foram identificados como Coenurus cerebralis, e os tecidos do cérebro submetidos complementarmente a exames histopatológicos para descrição da lesão.
