BACKGROUND Empirical evidence suggests that the prevalence of soil-transmitted helminth (STH) infections in remote and poor rural areas is still high among children, the most vulnerable to infection. There is concern that STH infections may detrimentally affect children's healthy development, including their cognitive ability, nutritional status, and school performance. Medical studies have not...

International Journal for Parasitology 25: 1185-1191. Experiments were carried out to compare tbe sensitivity of Ancylostoma ceyhnicum and Necator umericunus to ivermectin (IVM) and pyrantel in vitro. Loss of motility and inhibition of inges...

One hundred and eighteen (118) pregnant women were recruited into the study. The aim was to study the effect of soil transmitted helminthes in pregnant women vis-à-vis compared with other haematological parameters.Blood and stool samples were collected and analyzed with standard Haematological and Parasitological equipment.The result showed that there were anaemia, eosinophilia and raised plate...

Soil-transmitted helminth infections are among the most common infections worldwide and affect the poorest and most deprived communities. The three major soil-transmitted helminths (STHs), i.e., Ascaris lumbricoides, Trichuris trichiura and Necator americanus/Ancylostoma duodenale are among the most widespread parasites worldwide. It is estimated that more than 880 million children are in need ...

There are two types of hookworm, Ancylostoma duodenale, known as the Old World hookworm, and Necator americanus, the New World hookworm. While both species may be found in Africa, Asia and the Americas, N. americanus is predominantly located in the Americas and Australia, while only A. duodenale is found in the Middle East, North Africa and southern Europe (a). The origin of the New World speci...

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...

Hookworms are hematophagous nematodes that infect a wide range of mammalian hosts, including humans. There has been speculation for nearly a century as to the identity of the anticoagulant substances) used by these organisms to subvert host hemostasis. Using molecular cloning, we describe a family of potent small protein (75-84 amino acids) anticoagulants from the hookworm Ancylostoma caninum t...

Parasitic infections may damage various ocular tissues, thereby causing visual dysfunction. In 1950, Wilder described the first case in which larval forms of nematodal intestinal roundworms (Ascaridoidea: Ascaris, Toxocara, Ancylostoma, Necator, and Strongyloides) were implicated as a cause of intraocular disease. This review focuses on two disorders associated with parasitic infections: ocular...

A case of massive Ancylostoma sp. larval infestation is presented in a patient who had received systemic corticosteroid therapy. What attracts attention in this case is the exuberance and rarity of clinical manifestation. Based on the pertinent literature, we discuss the mechanisms of parasital infection, the natural history of the disease and its treatment.

" Even in cases of so-called beri-beri is the presence of the anchylostoma in them convincing evidence that they alone cause tbe disease and in the way suggested ? I think not."?Surg.-Major Dobson, Assam.?Report, 1892,^;. 66. " I altogether doubt the existence of any specific disease to which the term ankylostomiasis can be justly applied. * * * I maintain that it has yet to be shown that the p...
