Prevalence of Antibody to Toxoplasma Gondii Among Inhabitants Under Different Geographical and Climatic Conditions in Hyogo Prefecture, Japan

“…A significant difference in antibody prevalence was observed between inhabitants of districts with different amounts of rainfall. Although Remington et al (22) concluded no correlation between Toxoplasma infection and rainfall in their survey in E1 Salvador, high prevalence associated with heavier rainfall observed in the districts A and B may be explained by the fact that toxoplasma oocysts can survive longer in more humid soil. Kobayashi (2) described that sporulated oocysts survived at 7 C for 8 months in water, for 4 months at 66 % relative humidity and for 2 months at 32% relative humidity.…”

Toxoplasmosis and Congenital Sensorineural Hearing Loss in Saudi Arabia

“…3 There are numerous studies on the prevalence of the disease in different regions of the world. 5,[6][7][8][9][10][11][12] Differences in the epidemiology of the disease in various geographic locales and among population groups within the same locale are generally explained by differences in exposure rates to the two main sources of infection: the tissue cyst in the flesh of the animals and the oocysts in the soil contaminated by cat feces. Many studies from the Western world have emphasized a decline in the prevalence of toxoplasmosis.…”
