RESUMO
This study was carried out to determine the prevalence of intestinal parasites and their seasonal variation in northern Jordan. A total of 21 906 stool samples were collected over a period of 4 years [2009-2013] from 5 government hospitals in 3 cities. Samples were processed and examined microscopically and by concentration methods. Parasitic infection was found in 9611 samples [44%]. Giardia lamblia was the most prevalent parasite [41%] followed by Entamoeba histolytica [31%] and Ent. coli [13%]; the least prevalent parasites were Ascaris lumbricoides [1%], Hymenolepis nana, Taenia sp., and Chilomastix mesnili [all < 1%]. The prevalence of different parasites varied according to season, on average the summer months showed the highest incidence of parasitic infection [62%] compared with the winter months [16%]. Giardia lamblia and Ent. histolytica were most prevalent in the summer months
La présente étude a été menée afin de déterminer la prévalence de parasites intestinaux ainsi que leur variation saisonnière dans le nord de la Jordanie. Un total de 21 906 échantillons de selles ont été collectés sur une période de 4 ans [2009-2013] dans cinq hôpitaux gouvernementaux de trois villes. Les échantillons ont été traités et examinés à la microscopie et à l'aide de méthodes de concentration. Une infection parasitaire a été trouvée dans 9611 échantillons [44%]. Giardia lamblia était le parasite avec la prévalence la plus élevée [41%], suivi par Entamoeba histolytica [31%] et Entamoeba coli [13%]. Les parasites ayant la plus faible prévalence étaient Ascaris lumbricoides [1%], Hymenolepis nana, Taenia sp., et Chilomastix mesnili [tous < 1%]. La prévalence des différents parasites variait en fonction de la saison: en moyenne, les mois d'été affichaient la plus haute incidence d'infections parasitaires [62%] comparés aux mois d'hiver [16%]. Giardia lamblia et Ent. histolytica étaient les plus prévalents au cours des mois d'été

Food-handlers [n = 1500] attending the public health laboratory in Khartoum, Sudan, for annual check-ups were screened for intestinal parasites by 3 different techniques [direct faecal examination, formol-ether concentration and floatation] to evaluate the adequacy of annual screening. Results showed that 29.4% of food-handlers were harbouring intestinal protozoa in stool samples: Entamoeba coli in 15.3%, Giardia lamblia in 9.7%, and Enta. histolytica in 4.3%. Moreover, 2.7% of food-handlers harboured intestinal helminths: Hymenolepis nana [1.6%], Schistosoma mansoni [0.7%], Taenia saginata [0.3%] and Strongyloides stercoralis [0.1%]. We recommend more frequent screening of food-handlers and that the direct faecal smear technique is efficient for the detection of such parasites

We investigated the prevalence of bacterial and parasitic infections among workers in a pastry factory in North Lebanon in 2004. We found 39% of the workers [n = 196] had nasal carriage of Staphylococcus aureus. Resistance of S. aureus isolates was 98.7% to penicillin G, 24.7% to fusidic acid, 14.3% to pefloxacine and tetracycline, 11.7% to erythromycin, 6.5% to oxacillin and amoxicillin-clavulanate. Salmonella typhi was not found in any of the workers. Prevalence of intestinal parasites was 57.8% [n = 308]. Amoebae comprised 72.5% [68.3% Entamoeba coli, 15.5% E. histolytica], followed by flagellates [18.0 %] [37.5% Dientamoeba fragilis, 31.3% Giardia lamblia] and nematodes [7.8%] [only Ascaris lumbricoides]. The tuberculin test was positive in 16.3% of the workers [n = 301]
