ABSTRACT
The sialidase activity and genetic diversity of 22 Clostridium perfringens strains isolated from chickens with necrotic enteritis were determined. Sialidase activity was detected in 86.4 % of the strains. All C. perfringens showed a high value of similarity (>96 %), and they were grouped into seven clusters clearly separated from the other reference bacterial strains. From these clusters four patterns were defined in accordance with their phenotypic (sialidase production and antibiotic resistance profile) and genotypic (presence of nanI and nanJ genes) characteristics. Our results showed heterogeneity among strains, but they were genotypically similar, and it is suggested further studies are needed to better understand the pathogenesis of necrotic enteritis.
