Abstract
Since growth promoters ban in Europe, enteritis of different aetiologies (virus, bacteria and protozoa) are increasingly becoming the main cause of economic loss in commercial turkeys production. This study is focused on typing of Clostridium spp. isolated from samples of jejunum and ileum of 82 birds out of 17 turkeys flocks. The birds were 6-day to 104-day old, both male and female, with enteric disorders. The presence of toxin NetB was investigated. Multiplex PCR to detect cpa, cpb1, cpetx, cp1, cpb2 and cpe toxin genes were used for Clostridium typing. No lesions of necrotic enteritis were observed. Clostridium perfringens type A was isolated from 25 enteric samples, Clostridium difficile was found in 4 cases and Clostridium sordelli in one case. Clostridium perfringens was present from 6 to 104 days of age indicating its possible role in the enteric disorders of commercial turkeys. NetB toxin was found in no sample. 3 out of 4 isolates of Clostridium difficile were characterized by the presence of toxin genes.
