OBJECTIVE Our aim was to determine the Toxoplasma gondii IgG seroprevalence in HIV/AIDS patients who applied to our outpatient clinic. METHODS Between January 2006 and June 2010, 164 HIV/AIDS patients were tested for Toxoplasma gondii IgG antibodies by using the ELISA method. RESULTS Of the total of 164 HIV/AIDS patients, 135 were male, 29 were female with a mean age of 36 years (range: 20-...
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...
To study the distribution of tissue cysts in porcine tissues, 16 pigs were fed oocysts of 4 strains of Toxoplasma gondii (4 pigs/strain). Pigs were euthanatized between postinoculation days 103 and 875 and portions of 5 to 14 organs were bioassayed in mice and/or cats for T gondii. For bioassays, 50- to 100-g portions of tissue were incubated in acidic pepsin solution to free bradyzoites from c...
Introduction: Infection of pregnant women with Toxoplasma gondii during pregnancy may cause congenital toxoplasmosis in embryo and a number of serious and even persistent complications in newborns. One of the most effective factors determining the rate of congenital toxoplasmosis is the rate of Toxoplasma infection or immune status of women in child-bearing ages against the parasite.This study ...
Toxoplasmosis is a common and widespread infection in humans and many other species of warm–blooded animals. Toxoplasma gondii-derived heat shock protein 70 (Hsp70) may play an important role in the virulence of Toxoplasma gondii (T. gondii). In the present study, T. gondii Hsp70 was amplified by polymerase chain reaction (PCR) from the DNA of the T. gondiitachyzoite RH strain through the use o...
ONCEL, T., G. VURAL: Occurrence of Toxoplasma gondii antibodies in sheep in Istanbul, Turkey. Vet. arhiv 76, 547-553, 2006. ABSTRACT This study was carried out in order to determine the occurrence of Toxoplasma gondii antibodies in sheep in five districts of Istanbul, Turkey. A total of 181 sera taken from sheep were examined for antibodies to Toxoplasma gondii using an enzyme-linked immunosorb...
PURPOSE Toxoplasma gondii is a widespread protozoan parasite that infects a broad range of warm blooded animals as well as humans. The present study was investigated to evaluate the effects of allium cepa on renal failur in male rats which experimentally infected by Toxoplasma gondii, RH strain. METHODS Wistar male rat (n=40) were allocated into four groups, group one that received tachyzoite...
Toxoplasma gondii is a zoonotic protozoa of economic significance in livestock. Infected livestock meat and products act as a source of T. gondii infection in humans. Current drugs against T. gondii are limited by hypersensitivity and toxicity, and are not effective against the encysted bradyzoite stage of T. gondii. Thus, there is urgent need for safe and effective therapeutic agents against T...
Toxoplasma gondii isolates can be grouped into 3 genetic lineages. Type I isolates are considered virulent to outbred mice, whereas Type II and III isolates are not. In the present report, viable T. gondii was isolated for the first time from striped skunk (Mephitis mephitis), Canada goose (Branta canadensis), and black-winged lory (Eos cyanogenia). For the isolation of T. gondii, tissues were ...
Background and purpose: One of the transmission ways of the congenital toxoplasmosis is through the placenta to the fetus, therefore, its diagnosis at early stage is very important. Toxoplasma gondii parasite contains various antigens of which excretory-secretory antigens (E/SA) are used in designing Elisa avidity kit. The aim of this study was to compare the results of commercial kit and desig...
