Background Toxoplasma gondii is an apicomplexan protozoan parasite that infects one-third of the population of the world, including humans, animals, birds, and other vertebrates. The present investigation is the first molecular attempt in the Malakand Division of Pakistan to determine the epidemiology and phylogenetic study of Toxoplasma gondii infecting small ruminants.

Toxoplasma gondii is an obligate intracellular parasite belonging to the phylum Apicomplexa, which causes the zoonotic disease toxoplasmosis. T. gondii infects almost all warm blood animals. Generally, infected animals are asymptomatic and remain infected for life. Infection of humans occurs by consumption of infected undercooked meat or contaminated vegetables, fruit and water.

Toxoplasma gondii is an intracellular protozoan parasite that infects most warm-blooded animals, including humans, and causes toxoplasmosis. In this study, the pathogenicity of RH strain of T. gondii in broiler chicks was investigated and the susceptible tissues of chicks were clarified. Fourteen-day-old broiler chicks were injected intraperitoneally with 1×107, 1×106, and 1×105 tachyzoites of T. gondii, respectively.

The aim of this study was to identify three parasitic major abortion agents in all cattle aborted fetus samples and N. caninum and T. gondii in sheep and goat aborted fetus sent to Elazig Veterinary Control Institute during two years. Total genomic DNAs were obtained using a commercial kit. Real-time PCR analysis was performed separately for each agent. Conventional PCR was set up for confirmation of positive samples.

Toxoplasma gondii (T. gondii) is a facultative heterogeneous parasite that belongs to Apicomplexa and can infect almost all warm-blooded animals, including ruminants, birds and humans. To date, no information is available about the molecular investigation of T. gondii in large ruminants from Pakistan.

Pigs are one of several host species for Toxoplasma gondii, and consumption of infected pork may lead to toxoplasmosis in humans. The aim of this study was to develop an indirect enzyme-linked immunosorbent assay (ELISA) using surface antigen protein 1 (SAG1) of T. gondii for the diagnosis of porcine toxoplasmosis and to perform a serological investigation of pigs in Shandong province, China.

Toxoplasma gondii, a globally important food borne zoonotic parasite, infects most of the warm-blooded animals as well as people. Veterinarians and para vets are considered at risk of T. gondii exposure.

Toxoplasma gondii is an obligate protozoan parasite that can infect mammals and birds. Cats are the definitive host of T.

Objective
Toxoplasma gondii is a protozoan parasite that is widely prevalent in most warm-blooded vertebrates. Humans mainly become infected by eating raw or undercooked meat. This study was designed to investigate the infection of cattle with T. gondii in Jahrom, southern Iran.
