ancylostoma tubaeforme was originally described as a separate species parasitizing the cat. the adults of a. tubaeforme are 7 to 12 mm long. a. tubaeforme can be differentiated from the adults of a. braziliense and a. ceylanicum by the presence of three teeth. here we describe the first re­port of a. tubaeforme in a persian young female leopard, 2-3 years old, with head and trunk length 120 cen...

Reinfection with hookworm (Necator americanus) following chemotherapy was studied over 2 years in a rural village in Madang Province, Papua New Guinea. The prevalence of hookworm infection had returned to pre-treatment levels after 2 years, and the geometric mean hookworm burden had returned to 58% of the pre-treatment value. The rate of acquisition of adult worms was independent of host age, a...

While several mechanisms of immunoregulation have been demonstrated for hookworm and other neglected tropical infections, the influence of apoptosis in the immunomodulation of hookworm infection is still poorly understood. In this study, we demonstrate the cytotoxic and pro-apoptotic activity of hookworm antigens in Jurkat T cells, mesenteric lymph nodes lymphocytes of healthy and hookworm-infe...

BACKGROUND The infective stage of the parasitic nematode hookworm is developmentally arrested in the environment and needs to infect a specific host to complete its life cycle. The canine hookworm (Ancylostoma caninum) is an excellent model for investigating human hookworm infections. The transcription factor of A. caninum, Ac-DAF-16, which has a characteristic fork head or "winged helix" DNA b...

A cross sectional study was conducted in Jagapati Village, Bali to assess some characteristics of hookworm anemia among the adult population. Hookworm anemia was defined as an iron deficiency anemia in heavily infected individuals (EPG > 2,000). WHO criteria for anemia and criteria of Hercberg for iron deficiency were used. In this study, 15 cases of hookworm anemia were found among 454 total s...

BACKGROUND Microscopy-based identification of eggs in stool offers simple, reliable and economical options for assessing the prevalence and intensity of hookworm infections, and for monitoring the success of helminth control programs. This study was conducted to evaluate and compare the diagnostic parameters of the Kato-Katz (KK) and simple sodium nitrate flotation technique (SNF) in terms of d...

A survey of 108 individuals from a coastal Aboriginal community in north Western Australia revealed that two species of gastrointestinal protozoan parasites (Giardia duodenalis--39.8%, Entamoeba coli--40.7%) and five gastrointestinal helminths (Hymenolepis nana--54.6%, Hookworm [Ancylostoma duodenale]--30.6%, Enterobius vermicularis--6.5%, Trichuris trichiura--2.8%, Strongyloides stercoralis 1....

Anti-hookworm antibody serologic responses were measured in residents of an Anhui provincial Chinese village where Ancylostoma duodenale is the predominant hookworm. Antibody responses were measured against either soluble infective third-stage larval (L3) or adult antigens. Immunoglobulins of the IgG class, especially IgG4 correlated with both the prevalence and intensity of A. duodenale hookwo...

Hookworm infection is considered one of the most important poverty-promoting neglected tropical diseases, infecting 576 to 740 million people worldwide, especially in the tropics and subtropics. These blood-feeding nematodes have a remarkable ability to downmodulate the host immune response, protecting themselves from elimination and minimizing severe host pathology. While several mechanisms ma...
