The efficacy of Clindamycin and Monensin were evaluated in the prevention of oocyst shedding of kittens with Toxoplasma gondii (Tehran strain). In this study, 28 healthy kittens aged 1.5 – 2 months old divided randomly into 4 groups of seven. In group 1, Kittens were fed with the infected brain tissues of mice, all of seven kittens (100 %), shed oocyst, nearly 1 week after infection, which la...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 10, No. 12, December 2004 2257 species can cause disease (symptomatic infection) and death. C. felis and C. meleagridis infections showed low oocyst shedding (all seven patients had low to moderate oocyst loads in samples). On the contrary, C. parvum produced similar clinical manifestations but showed higher oocyst shedding; 46% had high to ...

To map QTL associated with disease resistance to avian coccidiosis and growth, two commercial broiler lines with different degrees of resistance to the disease were crossed to generate an F1 generation that was intercrossed to produce 314 F2 generation offspring. The F2 offspring were inoculated with sporulated oocysts of Eimeria maxima. Five disease-associated phenotypes were measured after th...

Ocular lesions are a common manifestation of toxoplasmosis in cats. In this survey, 10 healthy Syrianmice were infected through intraperitoneal inoculation of bradyzoites of Toxoplasma gondii (Tehran strain).Mice were killed 30 days after inoculation and the suspension of their brains was prepared, after confirmationof the infection. Seven kittens were fed with the infected mice brain suspensio...

This study examined the intestinal antibody response in 26 healthy volunteers challenged with Cryptosporidium parvum oocysts. Fecal extracts were assayed for total secretory immunoglobulin A (IgA) and C. parvum-specific IgA reactivity. Specific IgA reactivity was standardized to IgA concentration and expressed as a reactivity index (RI). Anti-C. parvum fecal IgA (fIgA) increased significantly i...

Cryptosporidium spp. cause diarrheal disease worldwide. Innate immune responses mediating resistance to this parasite are not completely understood. To determine whether MyD88-dependent pathways play a role in resistance to Cryptosporidium parvum, we compared the course of infection in MyD88(-/-) mice to that in their wild-type (WT) littermate controls. Three- to 4-week-old mice were infected w...

The members of the genus Eimeria infect a wide range of vertebrate hosts, such as swine, cattle, goats, sheep, rabbits, turkeys and chickens. It is now generally accepted that seven Eimeria species are recognised to parasitize the intestinal tract of the domestic fowl (Gallus gallus domesticus). Of all the Eimeria species that infect domestic fowl, Eimeria maxima is the most immunogenic species...

The aim of the present study was to determine seroprevalence of Toxoplasma gondii infectionin stray cats and correlation with oocyst shedding and IFN-γ concentration. From April to August 2016, one hundred fifty-nine stray cats were captured from various localities in Mashhad area. The blood and fecal samples were collected from each cat. The serum samples were examined to detect antib...
