SUMMARY Beginning in 1970, the potential of remote sensing (RS) techniques, coupled with geographical information systems (GIS), to improve our understanding epidemiology and control schistosomiasis Africa, has steadily grown. In current review, working definitions RS, GIS spatial analysis are given, applications made date RS for ecology Africa summarised. Progress been mapping prevalence infection humans distribution intermediate host snails. More recently, Bayesian geostatistical modelling...

Schistosomiasis is one of the major health problems in tropical and sub-tropical countries, with school age children usually being most affected group. In 1998 Department Health province KwaZulu-Natal established a pilot programme for helminth control that aimed at regularly treating primary schistosome intestinal infections. This article describes baseline situation impact treatment on S. haematobium infection cohort schoolchildren attending grade 3 rural part province.Primary from...
Host parasite diversity plays a fundamental role in ecological and evolutionary processes, yet the factors that drive it are still poorly understood. A variety of operating across range spatial scales, likely to influence both probability encounter subsequent infection. Here, we explored eight possible determinants richness, comprising rainfall temperature at population level, ranging behavior home productivity group age, sex, body condition, social rank individual level. We used unique...
We investigated environmental factors influencing the distribution of hookworm infection in KwaZulu-Natal, South Africa. Prevalence data were sourced from previous studies and additional surveys carried out to supplement database. When geo-referenced revealed that higher prevalences are limited areas below 150 m above sea level, low this altitude. Using univariate analysis we differences two areas. The relationship between prevalence, altitude climate-derived variables was assessed using...
Ten species of freshwater gastropod have been introduced into South Africa, mostly through the aquarium trade. Two these, Lymnaea columella (Lymnaeidae) and Physa acuta (Physidae), invasive in river systems across country for many years, probably since 1940s or 1950s, two recent arrivals, Tarebia granifera (Thiaridae) Aplexa marmorata are spreading. Research on one well-established invaders, P. acuta, is reviewed updated a suite attributes identified that may enabled it to become invasive.
Abstract Background Geohelminth infection is a major health problem of children from rural areas developing countries. In an attempt to reduce this burden, the Department Health province KwaZulu-Natal (KZN) established in 1998 programme for helminth control that aimed at regularly treating primary school schistosomiasis and intestinal helminths. This article describes baseline situation effect treatment on geohelminth part province. Methods Grade 3 schoolchildren Maputaland northern KZN were...
Two Asian freshwater gastropods, Radix rubiginosa (Michelin, 1831) (Lymnaeidae) and Gyraulus chinensis (Dunker, 1848) (Planorbidae) are reported from a facility supplying fish plants to the aquarium trade in KwaZulu-Natal, South Africa. Neither species has been found Africa previously. Both considered potentially invasive. Updated keys for Lymnaeidae spp. presented. An analysis of data on dates first collection regions origin all 14 snails known have introduced into country, regardless...
Information on hookworm infection and re-infection in a cohort of primary school children interview data their socioeconomic background behavior were combined with environmental using geographic information system (GIS). Multivariate models served to explore the covariation patterns adjusted for possible confounders. Our aim was identify factors that might serve predict thus guide control efforts when epidemiologic is insufficient. Furthermore, we wanted establish whether soil type has...
In order to study the effect of climate and topography on distribution common, intestinal nematodes in schoolchildren, changes prevalence were investigated along an altitudinal transect from approximately 50 m above sea level (asl), near coast, 1700 asl, foothills Drakensberg Mountains, KwaZulu-Natal, South Africa. These related several permutations temperature, rainfall evaporation, using univariate multiple regression analyses. A total 693 primary schoolchildren aged between 7 15 years was...
Abstract The historical phylogeography of the two most important intermediate host species human blood fluke Schistosoma mansoni , B. glabrata in New World, and pfeifferi Old was investigated using partial 16S ND1 sequences from mitochondrial genome. Nuclear an actin intron internal transcribed spacer (ITS)‐1 were also obtained, but they uninformative for relationships among populations. Phylogenetic analyses based on mtDNA revealed six well‐differentiated clades within : Greater Antilles,...
In line with the aims of National Bilharzia Control Programme and School Health Nutrition in Zambia, a study on urinary schistosomiasis was conducted 20 primary schools Lusaka province to further our understanding epidemiology infection, enhance spatial targeting control. We investigated risk factors associated schistosomiasis, examined small-scale heterogeneity prevalence, using data collected from 1,912 schoolchildren, 6 15-year-old, recruited Kafue Luangwa districts. The identified...
The prevalences and intensities of Ascaris lumbricoides, Trichuris trichiura hookworm (probably Necator americanus) infection were measured in the young children (aged 2-10 years) living 10 urban slums Durban, South Africa. Re-infection was assessed at 4-6 12 months post-treatment. baseline A. lumbricoides T. 81.7%-96.3% 54.5%-86.2%, respectively, corresponding geometric mean 960 91 eggs/g faeces. Most (85%) found infected with 23% those had moderate-heavy infections. A few investigated that...
The results of parasitological surveys have shown that both urinary and intestinal schistosomiasis occur widely among the human residents South Africa. national data on diseases now been incorporated into a geographical information system, to develop new maps based defined temperature constraints. disease data, obtained from 'hard-copy' atlas schistosomiasis, were used as template select regimes (1) suitable (2) unsuitable for transmission schistosomes humans in derived published...
SUMMARY Schistosoma haematobium is refractory to praziquantel (PZQ) during the prepatent period of infection. A hypothesis based on this observation that in areas where S. transmission seasonal, outcome chemotherapy depends timing treatment relative annual pattern. To examine hypothesis, a study was carried out southern Mozambique. Following demonstration seasonal transmission, PZQ administered separately two cohorts haematobium- infected schoolchildren (1) high and (2) low seasons followed...
Abstract The release of any species into a novel environment can evoke transmission parasites that do not normally parasitize the host as well potentially introducing new environment. Species introductions incur such risks, yet little is currently known about parasite fauna introduced primate over long term. We describe results long‐term monitoring intestinal an unprovisioned, reproducing population chimpanzees 40 years earlier (1966–1969) onto Rubondo Island in Lake Victoria, Tanzania,...
