Variations in the prevalence of antibody to toxoplasma gondii is reported from various countries (Hong Kong 9.8%, London 22%, New York 30%, Paris 84%) and from various cities in the same country(Jeddah 32%, Abha 51%). An area densely populated with cats is believed to be heavily contaminated with toxoplasma oocysts, leading to an increasing infection. As MedinaMunawarah has a large number of ca...

Sera from 495 pregnant women were examined for toxoplasma antibodies by indirect fluorescent antibody testing (IFAT). Antibodies were positive in 32.7%. Seropositivity was not increased significantly with age but showed a statistically significant rise in accordance with frequency of parity, abortion and contact with cats. The high rate of seronegativity (67.3%) observed in pregnant women ...

background: the prevalence of toxoplasma gondii infection in the blood donors has been poorly studied. the aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products. methods: a total of 250 blood products (112 fresh frozen plasma and 138 packed cells) in the blood transfusion institute, shiraz, iran were tested for spe-cific t. gondii antibodies (igg an...

the aim of this study was to determine the seroprevalence of toxoplasma gondii in mares and stallionsin the province of ankara. sera from 168 clinically healthy horses were tested for the presence oftoxoplasma gondii antibodies using the sabin feldman dye test. toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

As previously reported, normal human monocytes (11) and activated mouse macrophages (9) are able to kill or inhibit intracellular replication of Toxoplasma that are not antibody coated, whereas normal human and mouse macrophages are not (7, 9). Each of these types of mononuclear phagocytes is able to kill antibody-coated Toxoplasma. In our studies, phagocytosis of antibody-coated Toxoplasma sti...

A direct enzyme-linked immunosorbent assay (ELISA) is described that uses horseradish peroxidase-labeled antigen for detection of immunoglobulin M (IgM) and IgA antibodies to toxoplasma. In this assay, polystyrene microtiter plates were sensitized with anti-human IgM or IgA antibody to separate IgM or IgA from other classes of antibody. The presence of IgM or IgA antibodies to toxoplasma (Tox-I...

background toxoplasma gondii is a worldwide parasite which infects animals and human. infections with this zoonotic parasite are acquired mostly by consumption of undercooked or raw meat, which contains tissue cysts. objectives the current study was conducted to determine the seroprevalence of toxoplasma infection in farm animals in southern iran. materials and methods sera were obtained from 3...

Treatment of intact toxoplasma tachyzoites with individual mouse monoclonal antibodies to toxoplasma which are directed against individual membrane-associated antigenic determinants facilitated the phagocytosis of toxoplasma and also prepared the toxoplasma for intracellular destruction by nonelicited mouse peritoneal macrophages. In instances in which the organisms survived intracellularly, th...

Infection with Toxoplasma gondii is of medical importance in relation to a recent increase in cases of acquired immunodeficiency syndrome (AIDS). In the present study, we surveyed antibody to Toxoplasma among 1,761 people in Surabaya, Indonesia. The overall prevalence was 58% with significant differences between males (63%) and females (52%; P < 0.001). Although antibody prevalences at 0-9 year...
