Prevalence of Intestinal Parasites under Fingernails of Primary School Children in Zakho, Kurdistan Region

Abstract

In this study, 103 fingernails samples were collected (31 female and 72 male) from primary school children aged between 6 to12 years, which lived in Zakho city during the period from March to November, 2015. Each fingernail sample was immersed in normal saline, and subsequently centrifuged for 5 minutes at 2500 rpm. The supernatant was discarded; a few drops of the sediment of each sample were placed on the center of a clean glass slide with a drop of iodine or eosin, and then examined microscopically. The results revealed a total rate of 25.24% of infection with parasites. The recorded parasites with their rates included: eggs of Enterobius vermicularis, Hymenolepis nana, Ascaris lumbricoides and Trichuris trichaura (7.76, 5.82, 2.91 and 0.97 %, respectively) and cysts of Entamoeba histolytica and Giardia lamblia (4.85 and 2.91 %). According to age, the highest percentage of infection occurred in 9 years old children. Regarding the gender, males showed a higher rate of infection than females (17.47 % versus 7.76%, respectively). These results clarify the role of fingernails in the transmission of parasitic infections, which requires continuous cleaning and cutting.
