this investigation was performed on 1056 stool samples collected from isfahan area (with high intensity of infection) and dasht-mishan area of khuzestan. as indicated in tables 1, 2 and 3 the results of kato thick-smear technique is comparable to those conventional methods of formalin-ether and flotation methods, plus low cost, simplicity and practicability of kato's thick-smear. for ascaris eg...

This report describes a significant increase in the prevalence of hookworm infection in an area of Haiti where intestinal parasites are common, but hookworm has not been common. Changing environmental conditions, specifically deforestation and subsequent silting of a local river, have caused periodic flooding with deposition of a layer of sandy loam topsoil and increased soil moisture. We specu...

While the use of ancestry, ethnicity or race in contemporary medical and scientific research is controversial and the subject of debate in the United States, a hypothesis of ‘racial’ differentials in susceptibilities to disease has utility in the American historical context. This study employs a dataset of 542 residents of Marion County, South Carolina, collected in 1922 by medical teams to inv...

The risk of human hookworm infections from land application of wastewater matrices could be high in regions with high hookworm prevalence. A rapid, sensitive and specific hookworm detection method from wastewater matrices is required in order to assess human health risks. Currently available methods used to identify hookworm ova to the species level are time consuming and lack accuracy. In this...

BACKGROUND AND OBJECTIVES Hookworm infection is among the major causes of anaemia in poor communities, but its importance in causing maternal anaemia is poorly understood, and this has hampered effective lobbying for the inclusion of anthelmintic treatment in maternal health packages. We sought to review existing evidence on the role of hookworm as a risk factor for anaemia among pregnant women...

OBJECTIVE To estimate the degree of synergism between helminth species in their combined effects on anemia. METHODS Quantitative egg counts using the Kato-Katz method were determined for Ascaris lumbricoides, hookworm, Trichuris trichiura, and Schistosoma japonicum in 507 school-age children from helminth-endemic villages in The Philippines. Infection intensity was defined in three categories...

We compared the effects of larval and adult worm excretory-secretory (ES) products from hookworm on the proliferative responses and cytokine secretion in peripheral blood mononuclear cells (PBMCs) from hookwormpatients and egg-negative, nonendemic controls. When compared with negative controls, mitogen-stimulated PBMC from hookworm-infected individuals showed a significantly reduced proliferati...

Hookworm infection contributes around 700 million infections worldwide especially in developing nations due to increased use of wastewater for crop production. The effective recovery of hookworm ova from wastewater matrices is difficult due to their low concentrations and heterogeneous distribution. In this study, we compared the recovery rates of (i) four rapid hookworm ova concentration metho...

BACKGROUND Hookworms (Necator americanus and Ancylostoma duodenale) remain a major public health problem worldwide. Infections with hookworms (e.g., A. caninum, A. ceylanicum and A. braziliense) are also prevalent in dogs, but the role of dogs as a reservoir for zoonotic hookworm infections in humans needs to be further explored. METHODOLOGY/PRINCIPAL FINDINGS As part of an open-label communi...
