The seroprevalence of Toxoplasma gondii in the northern Greek population was determined in 1984, 1994 and 2004, and changes during this period were investigated. In total, 1014, 812 and 958 sera from individuals aged 1 day to 70 years were examined in 1984, 1994 and 2004, respectively, for IgG and IgM anti-Toxoplasma antibodies with the standard immunofluorescence assay (IFA) and microparticle ...

The parasite Toxoplasma gondii might harm the fetus if a woman is infected during pregnancy. IgG seroconversion and significant increase in IgG antibody amount in pregnancy indicates maternal infection. Presence of toxoplasma immunoglobulin M (IgM), immunoglobulin G (IgG) and low IgG avidity in a single serum sample indicates possible maternal infection, but positive toxoplasma IgM and low IgG ...

a total of 332 birds including 149 sparrows, 147 doves and 36 pigeons were examined for toxoplasma infection by both direct agglutination for detecting antibodies to toxoplasma and direct parasitological test to detect the cyst of toxoplasma in the brain of birds. the toxoplasma sero-positive rate (spr) in the examined birds was 10.5 percent (27 cases) with titers of 1:40 or higher and spr in e...

Effective primary prevention of congenital toxoplasmosis requires up to date information on locally relevant risk factors for infection in pregnant women. In Naples, risk factors for toxoplasma infection were compared in recently infected women (as assessed by detection of specific IgM in serum) and susceptible, IgG negative women. Recent infection was strongly associated with frequency of cons...

Intramuscular administration of Toxoplasma gondii lysate antigens to mice produced titers of T. gondii-specific antibody (measured by Sabin-Feldman dye test) greater than or equal to 1:1,024 in their sera. Intravenous administration of heat-killed Propionibacterium acnes to mice produced peritoneal macrophages with enhanced microbicidal capacity against T. gondii. Mice with high antibody titers...

Problem statement: In situations of immunodeficiency, Toxoplasma gondii emerges as a life-threatening infection. Toxoplasma gondii is transmitted parenterally, flourish in immunocompromised subjects and, most toxoplasma infections are asymptomatic. Studies have shown that there is a immunodeficiency in renal failure patient such as hemodialysis patients and these patients have a high risk for m...

BACKGROUND Latent toxoplasmosis, protozoan parasitosis with prevalence rates from 20 to 60% in most populations, is known to impair reaction times in infected subjects, which results, for example, in a higher risk of traffic accidents in subjects with this life-long infection. Two recent studies have reported that RhD-positive subjects, especially RhD heterozygotes, are protected against latent...

Toxoplasmosis is a zoonosis caused by infection with Toxoplasma gondii and is prevalent worldwide under various climatic conditions. It is usually asymptomatic, but infection in pregnant women can pose serious health problems for the fetus. However, epidemiological information regarding toxoplasmosis in Japanese pregnant women is limited. This study aimed to determine the prevalence of anti-Tox...
