The distribution of hookworm in schistosomiasis-endemic areas in Brazil was mapped based on climate suitability. Known biological requirements of hookworm were fitted to data in a monthly long-term normal climate grid (18 x 18 km) using geographical information systems. Hookworm risk models were produced using the growing degree day (GDD) water budget (WB) concept. A moisture-adjusted model (MA...

Soil-Transmitted Helminths (geo-helminths) are intestinal parasites causing human infections that soil-borne. The study assessed the level of soil contamination with geo-helminths ova and also evaluated compliance to WASH policies in some selected public private schools Akure North Owo Local Government Areas Ondo state, respectively. was conducted major districts two towns.

BACKGROUND Few studies have investigated the relative influence of individual susceptibility versus household exposure factors versus regional clustering of infection on soil transmitted helminth (STH) transmission. The present study examined reinfection dynamics and spatial clustering of Ascaris lumbricoides, Trichuris trichiura and hookworm in an extremely impoverished indigenous setting in r...

BACKGROUND The control of soil-transmitted helminth (STH) infections currently relies on the large-scale administration of single-dose oral albendazole or mebendazole. However, these treatment regimens have limited efficacy against hookworm and Trichuris trichiura in terms of cure rates (CR), whereas fecal egg reduction rates (ERR) are generally high for all common STH species. We compared the ...

BACKGROUND Hookworm disease is one of the most common infections and cause of a high disease burden in the tropics and subtropics. Remotely sensed ecological data and model-based geostatistics have been used recently to identify areas in need for hookworm control. METHODOLOGY Cross-sectional interview data and stool samples from 6,375 participants from nine different sites in Mbeya region, so...

BACKGROUND Inadequate nutrition; neglected topical diseases; and insufficient water, sanitation, and hygiene (WASH) are interrelated problems in schools in low-income countries, but are not routinely tackled together. A recent three-year longitudinal study investigated integrated school health and nutrition approaches in 30 government primary schools in southern Ethiopia. Here, we report on bas...

Hookworm infection is common but has rarely been reported in neonates or infants. Two cases of hookworm infestation in early infancy are described. The infants presented with malena, severe pallor, lethargy and failure to gain weight. Initial stool examination was non-contributory and diagnosis was made by upper gastrointestinal endoscopy.

stool examinations of 402 inhabitants of 8 villages in and around an area near zahedan, and 280 people who had emigrated from the rural area of zabol, revealed the following: the prevalence of infection with ascaris, trichuris and trichostrongylus was very low (less than 5%) in all areas surveyed, while the mean infection rates found for h.nana, hookworm and e.vermicularis (by stool examination...

BACKGROUND Microbial translocation (MT) is the process by which microbes or microbial products translocate from the intestine to the systemic circulation. MT is a common cause of systemic immune activation in HIV infection and is associated with reduced frequencies of CD4(+) T cells; no data exist, however, on the role of MT in intestinal helminth infections. METHODS We measured the plasma le...

BACKGROUND Worms may protect against allergy. Early-life worm exposure may be critical, but this has not been fully investigated. OBJECTIVES To investigate whether worms in pregnancy and in early childhood are associated with childhood eczema incidence. METHODS The Entebbe Mother and Baby Study, an anthelminthic treatment trial, enrolled pregnant women between 2003 and 2005 in Uganda. Mothe...
