Abstractbackground: Non-typhoidal salmonellosis is a worldwide distributed infection. It is a common enteric infection was caused by various Salmonella serotypes. It is considered as a foodborne disease, the direct transmission is commonly occurred between individuals. Many animal species, birds, and insects play an important role in transmission of infection to man.
Aim of study: This study aimed to investigate prevalence of enteric Salmonella infection with some influenced epidemiological parameters in patients in major three hospitals in Mosul city/Iraq.
Materials and Methods: A total 1028 stool samples were randomly collected from patients in three major hospitals (Al-Khansa, Ibin-Al Ether, and Al-Razy), - - . Salmonella-Shigella each. Isolated Salmonella colonies were serotyped in Central Health Laboratory in Baghdad.
Result & Discussion: Total isolation rate was 1.07%. Eleven salmonella isolates were identified: S.typhimurium (54.4%), S.agona (18.1%), and 9.09% for each of S.anatum, S.worthington, and the remaining non-serotyped species. High and low isolation rates were recorded in Jan.2001 and Nov. 2000 respectively. Salmonella isolation rate showed significant increase in patients of Al-khansa hospital (4.43%).A dramatic increase of Salmonella infection rate was recorded in diarrheic cases due to Samonella infection or concomitant enteric disease, similarly significant increase of Salmonella isolation rates (2.2%) were observed in children (6-to-10 years) due low education and little conciousness at this age, and in infants independent on breast feeding mainly due to contamination during preparation of milk bottles. Furthermore low infection rate recorded in males, and in those living in urban areas. A positive correlation was noticed between Salmonella infection and rearing of domestic animals in homes.
Conclusion: S. typhimurium was the dominant serovar. High isolation rates were recorded in diarrheic patients, in infant independent on breast feeding and children at primary school, people in rural areas were highly exposed to Salmonella infection than those in cities.
