Chirino-Zárraga et al (2006) have described the bacteriological characterization of C. pseudotuberculosis from18 Venezuelan goat flocks,which agreement the present study of bacterial isolation in goat.…”

“…O principal agente envolvido em casos de abscessos em linfonodos de pequenos ruminantes é o C. pseudotuberculosis (Chirino-Zárraga et al, 2006), isolado em todas as amostras de secreção coletadas nesse estudo, assim como nas trinta amostras de caprinos criados em Sobral, Ceará (Lima et al, 2005). Em Sergipe, o agente já havia sido isolado em abscessos superficiais de ovinos de uma propriedade de Nossa Senhora da Glória e em região ventral das vértebras torácicas (T11 a T13) de reprodutor caprino, utilizado de maneira consorciada por quatro caprinocultores (Rizzo et al, 2014).…”

“…O diagnóstico definitivo é realizado pelo cultivo do microrganismo, a partir de secreção obtida dos abscessos, onde à coloração de Gram observa-se formas cocobacilares (Chirino-Zárraga et al, 2006). Pode-se ainda realizar exames citológicos, histológicos, sorológicos e de biologia molecular para o diagnóstico da LC (Belchior et al, 2006.…”

Resumo O objetivo do estudo foi determinar a ocorrência e distribuição topográfica de linfonodos superficiais com alterações clínicas (hiperplasias, abscessos e/ou feridas em processo de cicatrização), sugestivas de Linfadenite Caseosa (LC), em pequenos ruminantes criados no estado de Sergipe. Entre os anos de 2011 e 2014, foram realizados exames clínicos de 1.908 pequenos ruminantes de 101 propriedades, inspeção e palpação de linfonodos superficiais, além do isolamento bacteriano de vinte amostras de secreções extraídas dos abscessos intactos. A ocorrência de animais com alterações macroscópicas em linfonodos superficiais foi de 7,18% (137/1908), sendo 5,19% (64/1.231) em ovinos e 10,8% (73/677) nos caprinos (p<0,001), acometendo 172 linfonodos. Dentre eles, 33,72% (58) eram o pré-escapular, 27,34% (47) submandibular, 15,11% (26) retromamário, 10,46% (18) pré-crural, 5,81% (10) parotídeo, 4,07% (7) retrofaríngeo, 1,16% (2) cervical profundo médio e caudal e 0,58% (1) cervical cranial e poplíteo. As regiões do tronco e posterior do corpo foram as que concentraram maior número de linfonodos alterados. Todas as amostras submetidas ao isolamento apresentaram crescimento de Corynebacterium pseudotuberculosis. A presença de animais, com sinais clínicos de LC, atenta para a necessidade da adoção de medidas profiláticas para controle da doença nos rebanhos sergipanos.Palavras-Chave: abscesso, Corynebacterium pseudotuberculosis, linfadenite caseosa. AbstractThe aim of the study was to determine the occurrence and topographic distribution of lesions suggestive of Caseous Lymphadenitis (CL) (abscesses, hyperplasia and/or wounds in cicatrization process) in superficial lymph nodes of the small ruminants bred in the state of Sergipe. Between years 2011 and 2014, were made clinical examinations of 1.908 small ruminants of 101 properties of the state, inspection and palpation of the superficial lymph nodes region. Bacterial isolation was realized on twenty samples of secretions of abscesses extract intact. The occurrence of animals with macroscopic lesions in lymph was 7.18% (137/1908), 5.19% (64/1,231) in sheep and 10.8% (73/677) in goats (p<0,001), affecting 172 lymph nodes. The topographic distribution of altered lymph nodes was 33.72% (58) in the prescapular, 27.34% (47) in the submandibular, 15.11% (26) in mammary, 10.46% (18) crural, 5.81% (10) in the parotid, 4.07% (7) retropharyngeal, 1.16% (2) in the middle deep cervical and caudal and 0,58% (1) in the cranial cervical and popliteal. The trunk and posterior regions of the body were concentrated greater numbers of altered nodes. All samples submitted to bacterial isolation were positive for Corynebacterium pseudotuberculosis. The breeders should be aware of prophylactic measures of CL, and the presence of an infected animal can serve as a source of dissemination of the disease in the herd.

“…Recently, results of reliable large-scale epidemiological study on the goat population in Brazil have been published (Seyffert et al 2010). Epidemiological studies carried out in other countries have usually been limited to the disease detection (Connor et al 2000, Chirino-Zarraga et al 2006. Some disease surveys were based on such small samples that results could not be considered reliable (Hein andCargill 1981, Batey 1986).…”

Epidemiological studies on caseous lymphadenitis were carried out in Poland in 1996 and 2002 among goat herds covered by a milk recording program. Between-herd seroprevalence was 13.2% in 1996 and increased to 62.5% in 2002. The average size of seropositive herds was statistically significantly higher than that of seronegative ones, however there was no statistically significant difference in the age between the herds. A statistically significant prevalence ratio (PR) was identified and relevant attributable risk for exposed animals (AR exp ) was calculated for the following risk factors: presence of seropositive males in a herd (PR=8.350; AR exp =0.651), presence of superficial abscesses in animals (PR=6.142; AR exp =0.620), presence of respiratory signs (PR=2.900; AR exp =0.393), presence of animals in poor condition in a herd (PR=2.774; AR exp =0.390) and occurrence of reproductive failures in a herd (PR=1.798; AR exp =0.230). Purchase of animals from abroad, mastitis and husbandry conditions (housing system, grazing system, hygienic conditions) were not shown to be statistically significant risk factors.
