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...

OBJECTIVES We sought to determine the prevalence of anti-Toxoplasma gondii antibodies in Yoremes and to identify associations of T. gondii exposure with sociodemographic, clinical and behavioural characteristics of Yoremes. DESIGN A cross-sectional survey. SETTING Yoremes were enrolled in the locality of Tierra Blanca in the municipality of Navojoa in Sonora State, Mexico. PARTICIPANTS We...

BACKGROUND Toxoplasma gondii (T. gondii) infection in blood donors could represent a risk for transmission in blood recipients. There is scarce information about the epidemiology of T. gondii infection in blood donors in Mexico. Therefore, we sought to determine the prevalence of T. gondii infection and associated socio-demographic and behavioral characteristics in a population of healthy blood...

The possibility of horizontal transmission of T. gondii was examined in squirrel monkeys. After three monkeys were inoculated perorally with 1.1-2.1 x 10(3) cysts of the T. gondii ME49, the animals were divided into two cages and maintained with one normal monkey for each cage as a cagemate. Two out of the three T. gondii-inoculated monkeys died, and the remaining one monkey was sacrificed in a...

BACKGROUND Toxoplasma gondii (T. gondii) infection in pregnant women represents a risk for congenital disease. There is scarce information about the epidemiology of T. gondii infection in pregnant women in Mexico. Therefore, we sought to determine the prevalence of T. gondii infection and associated socio-demographic, clinical and behavioural characteristics in a population of pregnant women of...

Toxoplasma gondii is an important pathogen in veterinary and human medicine. In this study, a new multiplex TaqMan real-time PCR for detection of T. gondii DNA was developed. This assay consisted of new sets of primers and probes which targeted B1 gene and ITS-1 region of T. gondii, with Vibrio cholera gene as internal control. The B1 gene primers were designed to detect T. gondii RH strain, wh...

OBJECTIVE To determine the seroprevalence of Toxoplasma gondii (T. gondii) in children with reactive hyperplasia of the cervical lymph nodes. METHODS This cross-sectional prospective study was conducted in Khartoum Children Emergency Hospital, Khartoum, Sudan between January 2010 and April 2011. Eighty children with cervical lymphadenopathy were selected using random sampling. Their lymph nod...

Infection by the protozoan parasite Toxoplasma gondii, is widespread in humans and many other warm-blooded animals. More than half billion of world human population has serum antibodies to T. gondii and Sheep and goats are more widely infected with T. gondii. T. gondii infection can be diagnosed indirectly with serological methods and directly by polymerase chain reaction (PCR), hybridization, ...

BACKGROUND Cats are definitive hosts of Toxoplasma gondii and play an essential role in the epidemiology of this parasite. The study aims at clarifying whether cats are able to develop specific antibodies against different clonal types of T. gondii and to determine by serotyping the T. gondii clonal types prevailing in cats as intermediate hosts in Germany. METHODOLOGY To establish a peptide-...

Background Through a cross-sectional survey, we determined the seroprevalence and correlates of Toxoplasma gondii (T. gondii) infection in women of reproductive age in Hermosillo City, Mexico. Methods We studied 445 women of reproductive age in Hermosillo City in the northwestern Mexican state of Sonora. Women were enrolled in the University of Sonora. Sera of women were examined for IgG and ...
