| patterns of infection with intestinal parasites in qatar among food handlers and housemaids from different geographical regions of origin. | intestinal parasitic infections were surveyed among recently arrived immigrant workers in qatar destined for employment in food handling occupations. two overlapping datasets (female workers surveyed in 2005 and 2006, and both sexes in 2006) were analyzed. seven species were detected, 3 nematodes (trichuris trichiura, hookworms and ascaris lumbricoides) and 4 protozoans (entamoeba histolytica/dispar, non-pathogenic entamoebae, blastocystis hominis and giardia lamblia). overall prevalence of infe ... | 2008 | 18457813 |
| molecular analysis of the enteric protozoa associated with acute diarrhea in hospitalized children. | pediatric diarrhea is a common cause of death among children under 5 years of age. in the current study, we investigated the frequency of intestinal parasites among 580 pediatric patients with chronic diarrhea. parasitic protozoa (all species combined) were detected by molecular tools in 22.9% of the children and the most common parasite was cryptosporidium spp. (15.1%). blastocystis hominis was detected in 4.7%, dientamoeba fragilis in 4%, giardia duodenalis in 1.7%, and entamoeba histolytica i ... | 2017 | 28824878 |
| multiplex polymerase chain reaction for detection of gastrointestinal pathogens in migrant workers in qatar. | the causes of infectious diarrhea among the migrant worker population in qatar are not well understood. we conducted a prospective observational study to understand the demographic and clinical characteristics and infectious causes of diarrhea among migrant workers in doha, qatar. a total of 126 male workers presenting to the qatar red crescent worker's health center outpatient clinic or emergency department were studied over a 5-month period in 2015-2016. epidemiologic surveys were administered ... | 2016 | 27928081 |
| a decade of intestinal protozoan epidemiology among settled immigrants in qatar. | the world health organization estimates that about 3.5 billion people worldwide are affected by intestinal parasitic infections. reports have already emphasized the role of immigrants in outbreaks of parasitic diseases in industrialized countries. with the mass influx of immigrants to qatar, patent intestinal parasitic infections have been observed. herein, the prevalence of intestinal protozoan infections was analysed in 29,286 records of subjects referred for stool examination at the hamad med ... | 2016 | 27496143 |
