ABSTRACT

The presence of Onchocerca guturosa in cattle is responsible for lesions similar to those observed in cases suspected of brucellosis, however, Onchocerca sp. is not a trade barrier, although it is also responsible for economic losses due to the removal of the affected parts of the carcasses. Brucella sp. is a zoonotic agent transmitted to humans through the consumption of contaminated animal products, the contact with infected animals and the handling of carcasses. This agent is also responsible for non-tariff trade barriers. Cervical bursitis is Brucella sp. suggestive lesions in bovine carcasses that requires laboratory tests to confirm the diagnosis. The objective of this study was to record the co-infection of Brucella abortus and Onchocerca sp. as a first report of co-infection of these two agents in the same lesion. The sample constituted of a nuchal bursitis in the cervical ligament, a suggestive lesion common to these two agents, submitted to histopathology and Brucella spp. isolation in the Brucellosis reference laboratory of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Brucellosis serological diagnosis were also performed in the animal's serum sample. B. abortus was isolated from the lesion and filarid nematode structures were identified in histopathology. All serological tests were positive for brucellosis. Further studies are needed, however, to understand the co-infection by Onchocerca sp. and B. abortus.

ABSTRACT

Os suínos são acometidos por diversas enfermidades e as verminoses se constituem como as principais causas de nãoganho de peso, competição e diminuição da conversão alimentar, descarte de vísceras ao abate e perdas financeiras. Onematoide Ascaris suum se constitui na principal parasitose na suinocultura nacional. Esse trabalho teve como objetivoavaliar o nível de infestação por A. suum em suínos em idade de abate provenientes de granjas tecnificadas localizadasna região do município de Piranga, região oeste da Zona da Mata, Minas Gerais, latitude 20º45’45’’S, longitude43º18’10’’W. Os animais foram abatidos em três matadouros localizados no município de Piranga, e foram observadosos tratos gastrintestinais dos suínos abatidos quanto à presença desse parasito. Foi observada a presença do nematoideem animais provenientes de 90% das granjas e a ocorrência total foi 22,4%, média de todo o período experimental.Também foi observado que, durante o período experimental, a ocorrência de A. suum no lume intestinal dos animaisnão apresentou diminuição e os protocolos de everminação não foram eficazes para a diminuição da ocorrência desseshelmintos nas propriedades onde foram empregados.


Swine are affected by several diseases and worms constitute the main causes of absence of weight gain, competitionand decreased feed conversion, discards of slaughter viscera and financial losses. The nematode Ascaris suum remainsa major parasitic disease in national livestock pigs. The objective of this work was to evaluate the level of infestationby A. suum in pigs at slaughter age provenient from intensive production systems located in Zona da Mata region,latitude 20º45’45’’S, longitude 43°18’10’’W, in tropical Southeastern, Brazil. The animals were slaughtered at threeslaughterhouses located in the municipality of Piranga, and their gastrointestinal tracts were observed in order toidentify the presence of those helminthes. We observed the presence of nematode in animals from 90% of the farms andthe total occurrence was 22.4%, media of all the experimental period. It was also observed that, during the experimentalperiod, the occurrence of A. suum in the gastrointestinal tube did not present reduction and the protocol to administeranthelmintic were not efficient to decrease the occurrence this helminthes in proprieties in which they were applied...
