“…The prevalence percentage reported demonstrates the widespread occurrence and distribution of Salmonella in Sudan. This prevalence was clearly higher than the range of 3.34 -4.0%, reported in the limited studies conducted previously (Soliman and Khan, 1959;Khan, 1962Khan, , 1970Yagoub and Mohamed, 1987;El Tom et al, 1999;Yagoub et al, 2006 andHag Elsafi et al, 2009).
