Abstract
Abstract (portuguese)
Estudo anterior, realizado pelos mesmos autores com aves consideradas susceptíveis ao agente do tifo aviário, sugeriu que a relação entre a bactéria e a aves restringe-se ao período da enfermidade. Neste trabalho avaliou-se a relação hospedeiro-parasita entre Salmonella Gallinarum e aves leves de postura comercial, consideradas mais resistentes ao tifo aviário. As aves não desenvolveram a doença clínica, mas a bactéria foi isolada do baço e do fígado quatro semanas após a infecção e, em algumas ocasiões, também do ovário.
Abstract (english)
Although the epidemiology of fowl typhoid in chickens supposedly involves a vertical transmission stage, a previous work run by the authors has suggested that this did not happen in a commercial line of laying hens highly susceptible to systemic disease with Salmonella Gallinarum. A new experiment was carried out in two other lines of commercial layers, considerably more resistant than those used in the previous study. Clinical fowl typhoid was not observed, but Salmonella Gallinarum was isolated from the spleen and liver four weeks after infection and, sporadically, from the ovary.
