@entity6497 ( @entity6497 ) chicks less than 3 mo age are observed to experience a high mortality rate that is often associated with @entity1681 . This study was undertaken to investigate the infectious bacteria implicated in @entity6497 @entity1573 @entity1681 . Postmortems were performed on 122 @entity6497 chicks aged from 1 d to 3 mo and intestinal samples were subjected to bacterial culture. Bacterial isolates were typed by PCR and serotyping. @entity526 (E. coli; 49%) was the most frequently isolated from the samples followed by @entity3168 ( @entity3168 ; 20%), Enterococcus spp. (16%), and @entity5746 spp. (7%). Of the @entity526 , 39% were categorized as enteropathogenic @entity526 , 4% enterotoxigenic @entity526 , and no enterohaemorrhagic @entity526 were found. The majority (93%) of @entity3168 was Type A and only 7% was Type E. @entity3168 Types B through D were not present. The @entity39577 gene that encodes @entity39577 toxin was identified from 16% of the @entity3168 isolated. All the @entity3168 Type E harbored the @entity39577 gene and just 10% of the @entity3168 Type A had this gene. Three @entity5746 serotypes were identified: @entity5746 Muenchen (S. Muenchen; 80%), S. Hayindongo (13%), and S. Othmarschen (7%). The indication is that the cause of @entity1681 in @entity6497 chicks is bacterial-involving: enteropathogenic @entity526 and enterotoxigenic @entity526 ; C. perfringens Types A and E (with the possible influence of @entity39577 gene); and S. Muenchen, S. Hayindongo, and S. Othmarschen.
