High Prevalence of Infection in Miners: A Case-Control Study in Rural Durango, Mexico.

Background: Very little is known about the seroepidemiology of infection with the parasite in miners. We determine the association of infection and the occupation of miner, and the association of seropositivity for with the socio-demographic, clinical, work and behavioral characteristics of the miners.

Toxoplasma gondii infection in interstate truck drivers: a case-control seroprevalence study.

Background: Infection with Toxoplasma gondii can be acquired via the ingestion of undercooked or raw meat containing tissue cysts, or via ingestion of water contaminated with oocysts. Professional long distance truck driving may have epidemiological importance for food-borne infections since drivers eat out of home and in places where hygiene and cooking practices are uncertain. We aimed to determine whether interstate truck drivers in Durango, Mexico have an increased risk of infection with T.

Lack of association between Toxoplasma gondii infection and occupational exposure to animals.

Background: Very little is known about the seroepidemiology of Toxoplasma gondii infection in ethnic groups in Mexico. Huicholes are an indigenous ethnic group living in a remote mountainous region in Mexico. We sought to determine the prevalence of anti-Toxoplasma IgG and IgM antibodies in Huicholes; and to determine the association of Toxoplasma seropositivity with socio-demographic, behavioral, and clinical characteristics of Huicholes.
