introduction toxoplasma gondii is one of the most important pathogen that has adverse effect on reproductive function. evidence acquisition recent studies revealed that infection with t. gondii not only affect female reproduction, also cause male reproductive impairment. in clinical studies, high prevalence of toxoplasmosis in sterile men has been reported. in animal models, toxoplasmosis is as...

Bivalves have been shown to be carriers of the human intestinal parasites Cryptosporidium parvum and Toxoplasma gondii. The goal of this study is to determine the prevalence of protozoan parasites in mollusks of New York City using a polymerase chain reaction (PCR)-based assay. Four species of mollusks, Mya arenaria, Geukensia demissa, Crassostrea virginica, and Mytilis edulis, were collected f...

BACKGROUND Toxoplasmosis is a common parasitic disease. There is likelihood of exposure to Toxoplasma gondii in blood donors during the periods of life. Currently, laboratory screening of blood donors for T. gondii is not routinely available. The objectives of this review were to study the effects of T. gondii on blood safety and to approach for risk reduction in blood recipients. METHODS A l...

Transmission of Toxoplasma gondii on swine farms was investigated using a deterministic dynamic computer simulation model. A primary focus was to evaluate a feline T. gondii vaccine. Animal populations (swine and cats) were compartmentalized based on the stage of T. gondii infection. Simulations were run under conditions of closed and equilibrium population size. Model parameters were varied in...

The prevalence of Toxoplasma gondii in free-ranging chickens (Gallus domesticus) is a good indicator of the prevalence of the parasite's oocysts in soil because chicken feed from the ground. The prevalence of T. gondii in free-range chickens from Ghana, Indonesia, Italy, Poland, and Vietnam was determined using the modified agglutination test (MAT). Antibodies to T. gondii were found in 41 (64%...

The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gondii in 50 free-range chickens (Gallus domesticus) from Amazon, Brazil, was determined. Antibodies to T. gondii were assayed by the modified agglutination test (MAT) and found in 33 (66%) chickens with t...

The present study was conducted to investigate the seroprevalence of Toxoplasma (T.) gondii in goats. Out of 200 goats 104 were seropositive showing an overall prevalence of 52%. T. gondii was more prevalent (55%) in female goats as compared to male goats (25%) with statistical significance (P<0.05). Results regarding the relationship between different breeds of goats and T. gondii revealed tha...

BACKGROUND Infectious agents are important in the pathogenesis of autoimmune disease since they are a major part of the environmental trigger of autoimmunity. A negative relationship between latitude and infectious disease species richness has been suggested. OBJECTIVES To examine whether their prevalence differs in two latitudinally different populations. METHODS The prevalence of infectio...

Background: Toxoplasma gondii, as an important food-borne protozoan parasite, occurs widely in humans and animals including domestic poultry throughout the world. The goal of this survey was to determine prevalence rate of T. gondii in free-ranging chickens sold in Tunis, Tunisia. Methods: In the present study, the prevalence of T. gondii in 40 free-range chickens (Gallus domesticus) marketed ...

toxoplasmosis is an important zoonotic diseases in human and animals. the disease caused by the protozoan toxoplasma gondii. to determine the infection rate of toxoplasmosis in sheep and goats in east azarbaijan province of iran a total of 186 sera, 13 fetal brains, 13 cotyledons and 34 whole blood samples were collected from sheep and goats in tabriz abattoir during the year 2010. serum sam...
