| the effect of repeated chemotherapy on age-related predisposition to ascaris lumbricoides and trichuris trichiura. | this study examines the persistence of predisposition to ascaris lumbricoides and trichuris trichiura during repeated chemotherapy in an urban community in kuala lumpur, malaysia. significant predisposition was observed over 2 periods of reinfection with and without age-standardization of data. analysis of different age groups indicated that predisposition was most strongly detectable in the younger age classes. the intensities of infection with both parasites were strongly correlated at each cy ... | 1992 | 1594301 |
| the role of some cyclorrhaphan flies as carriers of human helminths in malaysia. | the role of some adult flies (diptera: cyclorrhapha) as carriers of helminth parasites of man was studied at four sites in malaysia: a refuse dump, where no helminth-positive flies were detected, and in three peri-domestic situations where four species of flies carried up to three types of nematodes. the dominant fly species chrysomya megacephala (fabricius) carried eggs of the roundworm ascaris lumbricoides l., the pinworm trichuris trichiura (l.) and hookworm on the adult external body surface ... | 1988 | 2980156 |
| age-related prevalence, intensity and frequency distribution of gastrointestinal helminth infection in urban slum children from kuala lumpur, malaysia. | the gastrointestinal helminth infection status of 1574 children living in a slum area of kuala lumpur, malaysia was assessed by quantitative coprology. almost two-thirds were infected with trichuris trichiura, 49.6% with ascaris lumbricoides, and 5.3% with hookworm. infection prevalence rose rapidly to a stable asymptote at 7 years of age, and the age-intensity profile was convex with maximal values in the 5-10 year age classes. this pattern was the same for males and females, but differed marke ... | 1988 | 3188158 |
| aggregation and predisposition to ascaris lumbricoides and trichuris trichiura at the familial level. | this study examines the persistence of familial aggregation and familial predisposition to ascaris lumbricoides and trichuris trichiura infection over 2 periods of treatment and reinfection, in an urban community in kuala lumpur, malaysia. both parasite species were shown to be aggregated (assessed by the variance to mean ratio) within families at all 3 interventions, although no consistent trend in aggregation was observed over the period of the study. associations between mean a. lumbricoides ... | 1994 | 8153999 |
| prevalence of intestinal parasites among members of the public in kuala lumpur, malaysia. | a total of 246 stool samples were collected from the public who participated in a medical fair held at the university malaya medical center. the stools were examined for intestinal parasites using the formalin-ether concentration technique. the overall infection rate was 6.9% (17 out of 246), with trichuris trichiura being the most common parasite (4.5%), followed by ascaris lumbricoides (0.8%), clonorchis sinensis (0.8%), hookworm (0.4%), and entamoeba histolytica (0.4%). none of these particip ... | 2005 | 15906644 |
