Genotyping of Clostridium perfringens isolated from healthy and diseased ostriches (Struthio camelus)

摘要

Background and ObjectivesClostridium perfringens is more prevalent type of clostridia genus isolated from the intestinal tract of ostrich (Struthio camelus). Necrotic enteritis (NE) is a potentially fatal gastrointestinal (GI) disease of poultry and other avian species, which produces marked destruction of intestinal lining in digestive tract caused by C. perfringens. Pathogenicity and lesions are correlated with the toxins produced, thus toxin typing of the bacterium has diagnostic and epidemiological significance. The aims of the present study were to determine the biotypes of C. perfringens among ostrich’s farms either diseased and healthy ones and to screen the isolates for major toxin genes (cpa, cpb, etx, and iA, cpb2, and cpe).
