Some symptoms of menopause have also been described in patients with toxoplasmosis. Whether Toxoplasma gondii (T. gondii) infection has any influence on clinical manifestations of menopause is yet unknown. We sought to determine whether T. gondii exposure is associated with symptoms and signs of menopause. We performed a cross-sectional study of women attending a public health center in Durango...

It was generally believed that Toxoplasma gondii had a clonal population structure with three predominant lineages, namely types I, II and III. This was largely based on genotyping of more than 100 T. gondii isolates originating from a variety of human and animal sources in North America and Europe. Recent genotyping studies on T. gondii strains from wild animals or human patients from differen...

Toxoplasma gondii is an intra-cellular protozoan parasite that can infect almost all nucleated cells, eliciting host immune responses against infection. Host tissue damage is mainly caused by cellular lysis when T. gondii egresses from infected cells. However, the effects of cytokines released by host immune cells on egression of T. gondii remain elusive. This study aimed to investigate the rol...

BACKGROUND Toxoplasma gondii is a major problem for the sheep industry as it may cause reproduction problems. The importance of T. gondii in Norwegian goat herds is uncertain, but outbreaks of toxoplasmosis in dairy goat farms have been recorded. The aim of this study was to describe the prevalence of T. gondii infection in Norwegian dairy goats by using serology. FINDINGS Goat serum original...

Toxoplasmosis is a major zoonotic disease of warm-blooded animals caused by Toxoplasma gondii. Cats are the only definitive host and they excrete environmentally resistant T. gondii oocysts in their faeces. Coproscopy was used to detect oocysts of enteric coccidians and then Copro-PCR was employed to test specifically for T. gondii in 470 cat samples. The prevalence of T. gondii oocysts was 2.3...

BACKGROUND Infection with Toxoplasma gondii in water buffaloes (Bubalus bubalis) is of epidemiological importance because of the risk for transmission to humans. We sought to determine the seroprevalence of T. gondii infection in 339 water buffaloes in Veracruz State, Mexico using the modified agglutination test (MAT, cut off 1:25). Seroprevalence association with general characteristics of buf...

IL-12 and IL-23 are closely related in structure, and have been shown to play crucial roles in regulation of immune responses. However, little is known about the regulation of these cytokines in T cells. Here, we investigated the roles of PI3K and MAPK pathways in IL-12 and IL-23 production in human Jurkat T cells in response to Toxoplasma gondii and LPS. IL-12 and IL-23 production was signific...

CD8(+) T cells play a crucial role in the control of infection with intracellular microbes. The mechanisms underlying the CD8(+) T-cell-mediated clearance of the intracellular pathogen Toxoplasma gondii are, however, not completely understood. The effect of CD8(+) cytotoxic T-lymphocyte (CTL)-mediated lysis of host cells on the viability of intracellular T. gondii was investigated. Quantitative...

This study was conducted to evaluate oxidative stress using markers such as malondialdehyde (MDA), glu- tathione (GSH), total oxidant status (TOS), antioxidant capacity (TAC) and index (OSI) in sheep naturally infected with Toxoplasma gondii (T. gondii). A of 30 Morkaraman breed were used this study. Blood samples obtained from 10 healthy control 20 T. gondii. malondial- dehyde, GSH, TOS TAC le...

background toxoplasmosis is a widespread disease in humans and many other species of warm-blooded animals. among livestock animals, sheep and goat are more widely infected by toxoplasma gondii. this parasite is a major cause of abortion, with significant economic losses for sheep and goat breeders. objectives the polymerase chain reaction (pcr) method was employed to detect of the t. gondii dna...
