| the distribution of helminth infections along the coastal plain of kwazulu-natal province, south africa. | the results of a previous study indicated that, in the province of kwazulu-natal, south africa, necator americanus and strongyloides stercoralis were endemic to the coastal lowlands only. the prevalences of these helminths, as well as those of trichuris trichiura and ascaris lumbricoides, have now been investigated along a 1000-km-long transect through the coastal plain, at altitudes of < 300 m, from the mozambique border (26 degrees 57's) to the border with eastern cape province (30 degrees 53' ... | 1999 | 10715680 |
| influence of physico-chemistry and mineralogy on the occurrence of geohelminths in geophagic soils from selected communities in the eastern cape, south africa, and their possible implication on human health. | geophagic soils from selected communities in eastern cape, south africa were characterised to determine their properties and geohelminth content. the soils were coarse-textured with cation exchange capacity values ranging from 6.35 to 18.94 cmol (+)/kg. quartz was the dominant mineral in the samples with sio2, al2o3, and fe2o3(t) having the highest concentrations among major element oxides. the soil properties, mineralogical composition, and low amounts of particle binding substances may favour ... | 2014 | 23574040 |
