Resumo O aumento da população urbana contribuiu para que muitas pessoas escolhessem um animal de estimação independente, como o gato. Esta situação possibilita o abandono desses animais, aumentando o número de gatos nas ruas e nos abrigos. Esses animais, então, podem servir como fonte de infecção para outros hospedeiros. Entre 2014 a 2015 foi analisada a frequência de parasitos gastrintestinais em gatos cativos e de rua na cidade do Rio de Janeiro. Foram coletadas 91 amostras fecais de gatos cativos e 172 de gatos de rua, sendo essas processadas pelas técnicas de centrífugo sedimentação e flutuação. A frequência de parasitos nos gatos de rua foi 77,3%, sendo esta significativamente maior do que a evidenciada nos cativos, 49,5%. Os helmintos foram mais detectados, sendo ancilostomídeos os parasitos mais evidenciados. Também foram detectados, Toxocara cati, Cystoisospora sp. e Dipylidium caninum. Não foi observada diferença estatística na frequência de parasitos entre o sexo nos gatos cativos, porém nos de rua, os machos (85,5%) apresentaram positividade maior do que as fêmeas (71,8%). A elevada frequência de ancilostomídeos, agente da “Larva Migrans Cutânea” no homem, demonstra a necessidade de controle das infecções parasitárias nos gatos estudados.

Abstract The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Between 2014 and 2015, the frequency of gastrointestinal parasites in captive and stray cats in the municipality of Rio de Janeiro was analyzed. Ninety-one fecal samples were collected from captive cats and 172 from stray cats. Centrifugal sedimentation and flotation techniques were used. The frequency of parasites among the stray cats was 77.3%, and this was significantly higher than the frequency observed in captive cats (49.5%). Helminths were detected more frequently, and hookworms were the parasites most detected. Toxocara cati, Cystoisospora sp. and Dipylidium caninum were also detected. No statistical difference in the frequency of parasites was observed between the sexes among the captive cats. However, among the stray cats, males (85.5%) presented higher positivity than females (71.8%). The high frequency of hookworms, which are the agent for “cutaneous larva migrans” in humans, shows the need to control parasitic infections among the cats studied.

Este estudo teve por objetivo realizar um levantamento do conhecimento de 400 gestantes e puérperas atendidas na rede pública de saúde do município de Niterói, Estado do Rio de Janeiro sobre a toxoplasmose. Apenas 111 (27,8%) participantes relataram conhecer a doença. A maioria 289 (72,2%) nunca ouviu falar sobre a toxoplasmose, principalmente sobre as formas de prevenção da infecção pelo Toxoplasma gondii. Foi encontrada diferença significativa entre as pacientes que disseram conhecer a toxoplasmose e aquelas que relataram desconhecer a doença com relação à presença de anticorpos IgG anti- T.gondii (p = 0,013). Estes resultados permitem ressaltar a importância do rastreamento sorológico sistemático na infecção toxoplásmica, bem como a prevenção primária por meio de informações corretas durante o pré-natal, sendo esta uma importante medida de saúde pública a ser implementada.

The present study conducted a toxoplasmosis-related knowledge level survey with 400 pregnant and puerperal women attended in public health units in the municipality of Niterói, Rio de Janeiro. Only 111 (27.8%) women claimed to know about the disease. Most of them (n = 289; 72.2%) had never heard about toxoplasmosis nor knew how to prevent the infection by Toxoplasma gondii. A significant difference (p = 0.013) regarding the presence of anti-T. gondii IgG was observed between women who claimed to know about the disease and those who had never heard about it. These results highlight the importance of a systematic serological screening process for toxoplasmosis, as well as the importance of primary prevention by accurate information during prenatal care, an important Public Health action to be implemented.

IntroductionTo determine the prevalence of immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-Toxoplasma gondii antibodies among pregnant and postpartum women attended within the public healthcare system in Niterói, State of Rio de Janeiro, and to detect possible exposure factors associated with T. gondii infection in this population.MethodsIgM and IgG anti-T. gondii antibodies were investigated in 276 pregnant and 124 postpartum women by using the indirect immunofluorescence (IFAT) and immunoenzymatic assay (ELISA) techniques. The participants were selected by convenience sampling. All these 400 patients filled out a free and informed consent statement, answered an epidemiological questionnaire and were informed about the disease.ResultsAmong the 400 samples analyzed, 234 (58.5%) were reactive to IgG anti-T. gondii antibodies, according to the IFAT and/or ELISA assay. One pregnant woman was found to be reactive to IgM anti-T. gondii antibodies, with an intermediate IgG avidity test. Risk factor analysis showed that seropositivity was significantly associated (p<0.05) with age, contact with cats and presence of rodents at home. Through a logistic regression model, these associations were confirmed for age and contact with cats, while education at least of the high school level was found to be a protective factor.ConclusionsThe prevalence rate of IgG anti-T. gondii antibodies in the City of Niterói was high and the risk factors for infection detected after multivariate analysis were: age over 30 years, contact with cats and education levels lower than university graduate level.
