title: An outbreak of Salmonella typhimurium infection in bengalees, a variety of Lonchura striata.
abstract: Bengalees (a variety of Lonchura striata) in an aviary in Nagano Prefecture died of severe diarrhea in 1991. Pathological examination revealed slight enlargement of the liver and spleen. Histopathologically, necrotic granulomatous lesions were seen in the liver. Salmonella Typhimurium was isolated from the main organs and fecal samples. No evidence of Newcastle disease or chlamydiosis was detected. The disease was finally diagnosed as S. Typhimurium infection in bengalees. In spite of some countermeasures, 198 out of 268 birds died within 6 months, a mortality rate of 74%. Epizootiological survey revealed that the infection was transmitted by birds introduced from another prefecture. This is the first report of S. Typhimurium infection in bengalees.
