In Sub-Sahara Africa and developing countries, where the prevalence of parasitic infection is very high a dominant Th2 immune response has been reported and suggested to increase susceptibility to mycobacterium tuberculosis infection. Such an imbalance in an increase is Th2 cells favor IgE production. Peripheral eosinophilia is widely recognized as a useful indicator of parasitic diseases mainl...

Background: Despite continued and comprehensive planning of the world health organization (WHO), intestinal parasitic infections are a serious public problem in developing countries. Due to the high prevalence of cancers in Ardabil province and subsequently the high possibility of intestinal parasitic infections among the people, the aim of this study was to assess the frequency of intestinal p...

A total of 1570 adolescent girls (aged 10-19 years) of rural, urban and slum areas in and around Dhaka city were investigated to determine the association of anaemia with parasitic infection. About one third (33.50%) of the adolescent girls were found to be infected with one or more protozoans (Entamoeba histolytica, Giardia lamblia) and helminths (Ascaris lumbricoides, Trichuris trichura, Stro...

T helper (Th) cells produce signature cytokine patterns, induced largely by intracellular versus extracellular pathogens that provide the cellular and molecular basis for counter regulatory expression of protective immunity during concurrent infections. The production of IL-12 and IFN-gamma, for example, resulting from exposure to many bacterial, viral, and protozoan pathogens is responsible fo...

Immunoglobulin E (IgE) plays a central role in the pathogenesis of immediate hypersensitivity reactions because of its capacity to bind specifically to high-affinity IgE receptors on mast cells or basophiles by the alpha chain of Fc epsilon receptor type I (Fc-epsilon RI-α).1 In addition to its ability to activate mast calls and basophiles, IgE can bind to the low-affinity IgE receptor (CD23, o...

Parasitic dinoflagellates have recently emerged as significant disease agents of commercially important crustaceans. For example, epizootics of Hematodinium have seriously affected certain crab and lobster fisheries. The parasitic dinoflagellates of crustaceans are, however, relatively unknown. Marine crustaceans are parasitized by two orders of dinoflagellates: the Blastodinida and the Syndini...

We measured enteric parasitic infection prevalence and the effect of treatment on human immunodeficiency virus (HIV) RNA levels to assess their importance to HIV primary care in resource-limited settings. Adults in Lilongwe, Malawi, were evaluated, treated, and followed-up for parasitic and HIV infections. Of 389 patients, 266 (68%) were HIV infected. Helminth infections were more common in HIV...

Toxoplasmosis is a parasitic infection with public health importance. The aim of this study was to determine the seroprevalence toxoplasmosis and its risk factors among pregnant women consulted at Bamenda Regional Hospital.
