Frequency of Shigella, Salmonella species and Intestinal Parasites in a diarrheal diseases in Sinnar State

Abstract

Background: Diarrheal disease continues to be an important cause of morbidity and mortality among youngchildren in developing countries including Sudan. Globally, intestinal parasite, Shigella and Salmonella species remain major contributors to acute enteric infections. The study was aimed at determining the frequency ofintestinal parasite, Shigella and Salmonella species identified from diarrheic patients at Daweena Medical Centre, Abuhuggar Medical Centre, Abuhuggar Hospital and Senja model medical centre in Sinnar state. Methods: This study based cross sectional study was conducted from November to May 2016. Parasitic andbacterial identification was done using standard parasitological and bacteriologicalprocedures. Results: Out of the 103 stool samples, 48 (46.6%) samples were positive for intestinal parasite, Shigella and Salmonella species. Of these, 43 (41.7%), 2 (1.9%) and 5 (4.9%) samples were positive for intestinal parasites, Salmonella and Shigella species respectively. The dominant isolated parasite was Entamoeba histolytica with frequency of 11.7% followed by Hymenolepis nana (8.7%), then Giardia lamblia (7.8%). The least identified parasites were Ascaris lumbricoid and Taenia saginata about 1% for each one. The majority 29 (58%) of enteropathogens were found in patients aged 6-15 years. Whereas, 17 (34%) in patients aged 16-25 , 2 (4%) observed in patients aged 26-35 and 1( 2% ) pathogen observed within patients aged >5 and <45. Double parasitic infections were observed in 4 patients (3.9%). Conclusion: The presence of reasonably high amount of intestinal parasite and Salmonella and Shigella species, measures including health education, improvement of safe water supply and sanitation facilities is crucial
