| pathogenicity and antigenic components of excysted giardia lamblia isolated from patients in riyadh, saudi arabia. | giardia lamblia cysts were isolated from patients in riyadh, saudi arabia. cysts and trophozoites (from axenically excysted cysts) were given orally by gavage to mice to establish the pathogenicity of the riyadh isolate. there was no effect of varying the dose of administered parasite on parasite excretion or morbidity. a typical pathologic pattern of giardiasis was demonstrated by histologic methods and electron microscopy. antigenic components of the riyadh isolate were compared with the portl ... | 1991 | 1951852 |
| a preliminary survey of parasitic infections and nutritional status among school children in riyadh, saudi arabia. | a total of 320 school children in the model institute of the capital in riyadh, were clinically and parasitologically examined. thirty-five (10.94%) had intestinal parasites. entamoeba coli (61.91%) was found more frequently among the commensals, while giardia lamblia (28.57%) was the most common pathogenic parasite. all urines were parasite free. the low infection rate with gardia could be explained by the good physical and nutritional status and better sanitary and living conditions. | 1989 | 2708849 |
| the intestinal parasitic infections among children in riyadh, saudi arabia. | a total of 5421 children, 2726 apparently healthy and 2695 with clinical manifestations suggestive parasitic infection were subjected to stool examinations. giardia lamblia was found to be the most common intestinal parasitic infection among both groups. enterobius vermicularis followed among the patient group. abdominal pain and pruritus ani were the most common causes of referral in the patient group. other causes of referral were mainly associated with g. lamblia infection. | 1989 | 2768862 |
| intestinal parasites infection among immunocompromised patients in riyadh, saudi arabia. | this study was conducted to determine the prevalence of intestinal parasites among immunocompromised patients in riyadh, saudi arabia. fecal samples were collected from 136 immunocompromised patients (52 females and 84 males), aged 2 to 69 years. specimens were fixed with 10% formalin for 30 min (2-3 g fecal(-1)) and then concentrated by a formalin-ether sedimentation technique. samples were examined as wet saline mounts and in iodine preparation for detection of protozoan oocysts, cysts, helmin ... | 2010 | 20836300 |
| retrospective analysis of intestinal parasitic infections diagnosed at a university hospital in central, saudi arabia. | to review the intestinal parasites diagnosed in a university hospital in riyadh, kingdom of saudi arabia (ksa). | 2006 | 17106548 |
| elisa for detection of anti-giardia specific igm: response in serum. | infection with giardia lamblia (g. duodenalis, g. intestinalis) is common all over the world, especially in children. traditional diagnosis by faecal microscopy has only moderate sensitivity; serological tests, although not always positive, are acceptable to patients and useful in epidemiological studies. we show here that serum igm separated by column chromatography and assayed by an indirect elisa test can be a useful tool for the diagnosis of giardiasis. one hundred and thirty-nine positive s ... | 1993 | 8254709 |
| prevalence of intestinal parasitic infections in riyadh district, saudi arabia. | a total of 23,516 stool specimens collected from patients attending three medical centres in riyadh, saudi arabia, were examined for intestinal parasites. of these 5737 (24.4%) were positive. entamoeba histolytica (8.8%) and giardia lamblia (6.3%) were the commonest parasites found, and in the age group of one to 15 years. giardia was found in 14.8% of males and 11.9% of females. other intestinal parasites present included ascaris lumbricoides, trichuris trichiura, schistosoma mansoni, hymeolepi ... | 1986 | 3675035 |
| pattern of intestinal parasitic infection in preschool children in riyadh, saudi arabia. | a total of 1,167 stool specimens collected from 0.6-6 years old patients attending king abdel aziz university hospital (kauh) in riyadh, were examined for intestinal parasites. of these 243 (20.8%) were positive. giardia lamblia (13.5) and enterobius vermicularis (4.2%), were the commonest parasites found. other parasites present include ascaris lumbricoides, entamoeba histolytica and hymenolepis nana. abdominal pain (38.6%) and diarrhoea (27.6%) were the most common causes of referral presented ... | 1989 | 2809181 |
| haematological values and parasitic infections in school children in riyadh, saudi arabia. | a total of 1426 apparently healthy saudi children, were subjected to clinical and laboratory investigations of blood, urine and stools. lower means were observed for hb concentration, hot ratio, rbc and wbc counts. the mcv was in the range of western levels. of 1343 stool specimens 156 (11.6%) were positive for intestinal parasites (5.4% pathogenic and 6.3% commensals). the higher infection rate of commensals strongly suggests the presence of potentially infectious environmental sources and a pu ... | 1991 | 1765697 |
| cryptosporidiosis in young children suffering from diarrhoea in riyadh, saudi arabia. | a one-year study of patients (0-120 months of age) with diarrhoea at king abdel-aziz university hospital (kauh) in riyadh, saudi arabia, detected two cases of cryptosporidiosis. stool specimens from 174 children with diarrhoea and negative for other parasitic infection were examined using a safranin-methylene blue stain (s-mb). two children (l.1%) were showing cryptosporidium oocysts. none of 50 control children who did not have diarrhoea and was free of giardia lamblia was cryptosporidium posit ... | 1992 | 1300355 |
