Relationship between intestinal Schistosomiasis and enteric fever among Sudanese patients, New Halfa Town, Kassala State, Sudan

The present study was conducted in New Halfa Agricultural Scheme, Kassala state during the period from March to April 2011. The study aimed to determine the association between intestinal schistosomiasis and typhoid fever. Seventy-five (n=75) schistosomiasis patients were included in this study, they were 26 males (38.7%) and 49 females (61.3%) with different ages ranging from 1 to 60 years. The stool and blood samples were collected. The stool samples were examined to detect the eggs of Schistosoma mansoni by using wet preparation and calculating the number of eggs by using Kato Katz technique. The stool samples were cultured in MacConkey agar and Xylose Lysine Deoxycholate (XLD) agar to isolate Salmonella species, and the serum samples tested for antibody titer by using Widal test (slide method). The results showed that 16 out of 75 (21.3%) exhibited positive growth for the genus salmonella, eleven (11) were Salmonella paratyphi B (14.7%), while four (4) were Salmonella typhi (5.3%). Widal test revealed that 43 out of 75 (57.3%) were insignificant (1/20, 1/40), 15 out of 75 were suggestive (20%) and 17 out of 75 were significant (22.7%). Furthermore, there was no significant association between typhoid fever and intensity of intestinal schistosomiasis (P> 0.05) and no significant variation between antibody titers and intestinal schistosomiasis (P> 0.05).
