Prevalence of Intestinal Nematodes of Patients Consulting Outpatient Clinics in Hospitals and Health Centers in Neinava Governorate, Iraq

A survey was carried out to investigate the nematode parasites in three successive years (2009~2011) in Mosul city, its suburbs and villages. Five species of nematodes were recorded namely: Enterobius vermicularis , Trichuris trachiura , Strongyloides stercoralis , Ancylostoma duodenale and Ascaris lumbricoides . The highest infection rate was by E. vermicularis (92.05 %) in female of age 1~4 in 2010 then by T. trachiura (71.42%) in the year 2009 and in age 1~4, then by S. stercoralis (62.5%) in the 2011 in age 1~4, then A. duodenale (58.33%) in the 2010 in age group 5~14, and lowest infection rate was by A lumbricoides (39.13%) in the year 2011 in age group 5~14. It can be concluded that all above infection rates are high compared to the previous studies, and to the surrounding countries, possibly due to many factors such as low hygienic level, some bad habits especially in defecation, in addition to deterioration of infrastructure due to wars.
