Através de técnica imunoenzimática (E.L.I.S.A.) pesquisou-se a presença de anticorpos anti-Toxocara no soro de 79 mulheres adultas, residentes no município de São Paulo, que possuíam, ou possuíram nos dois últimos anos, cães em seus domicílios e de 123 homens adultos, funcionários da Prefeitu… Show more

“…Seroprevalence is highly variable, but children are considered the most likely exposed population, due to outdoor activities and frequent contact with dogs and cats (75,97). Interestingly, there is not a clear association of human toxocariasis with the presence of pets in the house, probably because contaminated outdoor areas are the main source of infection (45). Infective Toxocara eggs can remain viable for months or years in the environment, which increases the chance for their dissemination by paratenic hosts or by rain and wind (75).…”
