objective: sera from 186 sheep (93 rams and 93ewes) from tabriz, north-west of iran were evaluated for antibodies to toxoplasma gondii using a commercial elisa kit. methods: the animals were divided into two age groups (< 2 years, and > 2 years). results: antibodies to t. gondii were found in 13 of 186 sheep (6.98%). infection rate in ewes was higher than rams but this difference was not signif...

The present study was performed to clarify whether structural proteins are constituants of the antigens of Toxoplasma gondii which circulate in the sera of experimentally infected mice. Rabbits were immunized with mice sera containing circulating antigen, the rabbit sera were then tested for antibodies against Toxoplasma gondii. Low titers of specific antibodies, directed against cell wall prot...

Multiplication of Toxoplasma gondii was examined in vitro in murine erythroid cells at different stages of development. Toxoplasma gondii multiplied in nucleated erythroblasts and enucleated reticulocytes from the foetal liver, and in immature reticulocytes and yolk-sac derived erythrocytes from the foetal circulation. However, the rate of multiplication was lowered as erythroblasts matured, an...

Toxoplasma gondii can infect all species of warm-blooded animals, including humans, and causes serious diseases in immunocompromized hosts. Live tachyzoites derived from serial passage in HeLa culture were used in the Sabin-Feldman dye test for detection of Toxoplasma gondii antibody in serum samples of 21 captive wild felids including one fishing cat (Prion nailurus viverrina), one leopard (Pa...

A survey was carried out to determine the prevalence of Toxoplasma gondii antibodies among cattle farmers and cattle in the Gombak District, Selangor. A total of 79 human and 73 cattle serum samples were tested for Toxoplasma gondii antibodies by the immunofluorescent technique (IFAT). Results of the survey showed that anti-Toxoplasma gondii antibodies were found in 27.8% of the farmers, while ...

BACKGROUND The effects of extremely low frequency electromagnetic fields (ELF-EMF) on Toxoplasma gondii have not been explained yet. The aim of this study was to assess the possible effects of ELF-EMF on growth, survival time and viability of Toxoplasma gondii. In addition, the life span of Toxoplasma infected animals was investigated. METHODS Sixty adult male BALB/c mice were used for in viv...

BACKGROUND Toxoplasma gondii is an intracellular parasite, which infects one-third population of world. Humans and animals acquire infection by ingesting oocytes from feces of cats or by meat of other animals having cysts that may lead to congenital, ocular or cephalic toxoplasmosis. Either it is important to detect T. gondii from meat of food animals from retail shops or directly at slaughterh...

Introduction: Toxoplasma gondii is one of the most important foodborne pathogens. Toxoplasmosis causes abortion and neonatal loss in livestock and imposes significant losses to farming industry. Prevalence of T. gondii in sheep and goats was investigated in three adjacent geographical areas within Gilan province in north of Iran. Methods: Serum samples were collected from 247 sheep and 155 goat...

objective: toxoplasmosis infection has spread throughout the world, it is created by the intracellular protozoan toxoplasma gondii. toxoplasma cause changes in the behavior of the rodents. rodents play an important role in the life cycle of the toxoplasma gondii, they are the main infection reservoir of the domestic cats. the purpose of this study was to investigation toxoplasma infection in th...
