Abstract
The majority of the population in Yemen lives in rural areas and suffers from parasitic infections. Therefore, the present study aimed to determine the prevalence of intestinal parasitoses and schistosome infections among the students enrolled in the primary schools in Hajjah governorate – north of Yemen, along with an assessment of praziquantel (PZQ) in the treatment of microscopy-confirmed cases of Schistosoma mansoni and Schistosoma haematobium. For this purpose, 780 samples (320 stool and 460 urine) were examined microscopically. The present study revealed an overall infection rate of 75.3% (241/320) with intestinal parasites and Schistosoma mansoni. The detected parasite species included Entamoeba histolytica (27.8%), Hymenolepis nana (12.2%), Giardia lamblia (9.7%), Entamoeba coli (9.4%), S. mansoni (9.1%), Ascaris lumbricoides (6.9%), Trichuris trichiura (3.1%), Enterobius vermicularis (2.8%) and Ancylostoma duodenale (2.2%). Schistosoma haematobium was prevalent among 1.7% (8/460) of the investigated students. On the other hand, PZQ yielded a cure rate of 75.7% of Schistosoma-infected students when administered at 40 mg/kg body weight. However, a 100% cure rate was achieved when administered at 60 mg/kg body weight. Therefore, the findings of the present study highlight the importance of monitoring PZQ efficacy through large-scale studies in different settings endemic for schistosomosis in the country.
