Prevalência e fatores de risco da infecção humana por Toxocara canis em Salvador, Estado da Bahia

Abstract

Prevalência e fatores de risco da infecção humana por ABSTRACTIntroduction: Larva migrans visceral is caused by Toxocara sp and has never been studied in Bahia. This work investigated the prevalence and risk factors for infection by Toxocara canis in individuals from Salvador, State of Bahia. Methods: Three hundred and thirty-eight individuals were investigated for the presence of serum IgG anti-T. canis. Results: IgG anti-T. canis was higher in individuals from lower social classes who had more contact with dogs and cats, indicating that these variables are factors risk for this infection. Conclusions: The prevalence of T. canis infection was high. The risk factors for this infection identified are in agreement with in the literature.

A Systematic Review of Toxocariasis: A Neglected But High-Prevalence Disease in Brazil

“…This association may be related to the lack of knowledge of the population in relation to forms of infection, as well as to contact with dogs and cats that have not been dewormed. 41 Another study, conducted by Santarém and others in 2011 in the municipality of Presidente Prudente, São Paulo, also examined the association between social class and seropositivity for Toxocara. The results showed that being in the upper middle class was a protective factor both for the total population and for subgroups (middle class and lower class).…”

Human Toxocariasis: Prevalence and Factors Associated with Biosafety in Research Laboratories

“…21 Somatic antigen of Ascaris suum. This antigen was produced from adult female Ascaris suum nematodes acquired from a slaughterhouse in the city of Pelotas, Rio Grande do Sul, Brazil, following the methodology described by Souza and others) 3 to avoid cross-reactions with the antigen TES. The concentration of TES protein antigen was determined using the BCA method.…”

“…2 The disease is most prevalent in tropical, developing countries. 3 In Brazil, the prevalence rates recorded for Toxocara spp. in the adult population range from 8.7% to 46.3%.…”

Avaliação Soroepidemiológica Da Infecção Por Toxocara SPP Em Crianças Indígenas

“…Em relação ao diagnóstico da toxocaríase humana, esse se baseia em um conjunto de dados clínicos, laboratoriais e epidemiológicos. Em relação às alterações laboratoriais observam--se aumentos de leucócitos, eosinófilos e globulinas séricas, além de títulos elevados de IgG específica para Toxocara spp., no soro, fluídos oculares e líquido cerebrospinal (11)(12) . O diagnóstico laboratorial padrão para a toxocaríase é realizado pela técnica imunoenzimática (ELISA), que utiliza antígenos excretores e secretores do T. canis (TES), e apresenta alta sensibilidade e especificidade.…”
