abstract

background: toxoplasma gondii is a zoonotic protozoan parasite found worldwide and responsi­ble for major economic losses in most classes of livestock. this study was aimed to deter­mine the prevalence of t. gondii infection in sheep, cattle and horses in urmia, north-west of iran, using mat. methods : blood samples of 276 livestock and 26 horses were collected from july 2009 till april 2010. the data were analyzed by the chi-square, fisher's exact and cochran's and mantel-haen­s­zel tests. the level of significance was set at p < 0.05. results: thirty-three (21.1%) sheep, 2 (1.6%) cattle and 3 (11.5%) horses were seropositive to t. gondii . analysis showed that sheep were 15 times more likely to be seropositive comparing to cattle also 2 times more likely to be seropositive than horses. conclusion: this study showed seroprevalence of equine t. gondii infection with a considerable rate in sheep in urmia, northwest of iran. more comprehensive studies on livestock toxoplasmo­sis are required for further analysis of the parasite reservoir for human infection.

Serological Survey of Antibodies to Toxoplasma Gondii in Sheep in North-West of Iran

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 differe...

Seroprevalence of Toxoplasma gondii in pigs, sheep, goats, and cattle from Grenada and Carriacou, West Indies.

Prevalence of Toxoplasma gondii infection in pregnant women in Grenada is considered high. Little is known of the epidemiology of T. gondii infection in Caribbean Islands. Serum samples of 750 food animals in Grenada and Carriacou were tested for antibodies to T. gondii by the modified agglutination test (MAT). Antibodies to T. gondii (MAT, 1∶25 or higher) were found in 23.1% of 247 pigs, 44.1%...
