The Bacterial Causes of Camel-calf (Camelus dromedarius) Diarrhea in Eastern Sudan.

Fecal samples were collected from diarrheic camel-calves owned by nomadic pastoralists in the Butana Region. They were examined for 5 types of bacteria reported to cause the diarrhea. Sixty nine E. coli (66%), 14 Salmonella spp. (13%) and 11 Clostridium perfringens (10%) isolates were obtained from the samples. However, neither Campylobacter spp. nor Yersinia enterocolitiaca were isolated. The E. coli probing revealed the presence of K88, F41 adhesion factors and StaP, STb, LT, SLTII enterotoxins, while a high molecular weight plasmid was evident in the plasmid analysis profile. Thirteen of the Salmonella isolates were serotyped using group and specific antisera to be identified as Salmonella typhi strain.
