Septicemic salmonellosis in a two-humped camel calf (Camelus bactrianus).

Abstract

A 1-week old, two-humped female camel (Camelus bactrianus) calf with continual whining, epiphora, anorexia, muscle twitching, and lateral recumbency was referred to a veterinary hospital. Although she died shortly after preliminary clinical examination, but necropsy was performed and tissue samples were taken for further microbiological and pathological examinations. On bacteriological investigation, Salmonella typhimurium and Streptococcus agalactiae were isolated. Histopathologically, lesions consisted of hyperemia and hemorrhage in all serosal and mucosal surfaces, gastroenteritis, and purulent ascites, associated with suppurative omphalitis. Acute nutmeg liver demonstrated centrilobular congestion and moderate fatty changes without any inflammatory cell infiltration. The abomasal and intestinal mucosa were hemorrhagic and erosive. The brain was hyperemic with severe fibrinopurulent meningoencephalitis. Except for dromedary camels and llamas, there has been no previous report of an acute, fatal septicemia in a two-humped camel calf due to S. typhimurium accompanied by S. agalactiae.
