“…From an epidemiologic point of view, by having free access to recreation and leisure sites (beaches, parks, gardens and squares), pets may contaminate the soil, releasing nematodes eggs in their feces and posing risks to human users (MENTZ et al, 2004;CAPUANO;ROCHA, 2006;SANTOS et al, 2006;OLIVEIRA, 2007;SPÓSITO;VIOL, 2012;VITAL et al, 2012). These eggs remain viable in the environment for lengthy periods due to the consistency of their outer cuticle, exposing the human population to the risk of infection and disease development (NIJSSE et al, 2015).…”

Helminths and protozoa are examples of endoparasites that, during their biological cycles, can alternate between free-life stages and parasitic stages in the environment. Pets, such as dogs and cats, live together with humans and play a significant role in society; however, these animals may carry many parasites which, besides showing direct pathogenicity to the host, represent risks to human health, as is the case with parasitic zoonoses. Public areas like parks, gardens, squares, and beaches may offer risks to human users since these environments may contain feces deposited by parasitized dogs. This study verified the occurrence of helminth eggs and/or protozoan cysts or oocysts in fecal samples collected from sand strips at the beaches Armação do Pântano do Sul, Campeche and Morro das Pedras, in the south of Florianópolis Island, Santa Catarina State (SC), during the summer period. Pet feces were collected in the 2016-2017 summer season, from December 2016 to February 2017. In the Laboratory of Animal Parasitology (CCA/UFSC), fecal samples were processed based on Willis-Mollay flotation technique and Hoffman sedimentation technique. Samples from all three analyzed beaches were positive for the presence of parasites and fecal material was found along the seashore, sites where people freely walk barefoot. Of 104 fecal samples collected, 45 (43.27%) were positive for one or more parasites. The greatest prevalence was found in Campeche Beach, which had 72.22% positive samples. Ancylostomids were most prevalent, indicating that cutaneous larva migrans is likely to occur in humans. Other parasites such as Trichuris vulpis, Toxocara spp. and Giardia spp. were also detected in coproparasitological analyses. Based on the results, it was concluded that contamination of the beaches in Florianópolis Island, SC, constitutes a public health problem due to the possibility of zoonosis transmission. These results reinforce the importance of establishing health programs for parasite control and education programs to elucidate the risks of transmission of these zoonoses to the population, in an attempt to reduce environmental contamination risks at beaches of seaside resorts.

“…Vários estudos apontam para uma alta contaminação do solo em áreas de uso coletivo como praças de recreação e praias. Em Salvador, foram encontradas frequência de 29,4% de contaminação do solo por ovos desse helmimto 13 . No entanto, os dados acima citados são bem inferiores aos descritos em Santa Maria, RS, com 91,7%, das amostras de solo contaminados 6 .…”

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 high prevalence of toxocariasis has been observed in many countries worldwide, especially in tropical countries. The present study aimed to estimate the prevalence of toxocariasis and its associated factors in 100 children from a public school in the city of Belo Horizonte, Brazil. Sociodemographic data, lifestyle habits, self-reported health conditions, as well as characteristics related to housing and the presence of pets, were collected. In addition, clinical exams, anthropometric measurements, and laboratory exams (hemogram, total IgG, total IgE, and anti-Toxocara canis IgG ELISA) were carried out. Among the evaluated children, 15% presented positive serology for toxocariasis. The participants with positive and negative results were compared by means of either a Student's t test, for the two samples, or the Mann-Whitney test, and only the total IgG parameter proved to be statistically different among them. Considering the positive serology, the variable of age, the presence of puppies, contact with the ground, and the BMI (thinness) status proved to be significantly associated. These variables were included in a multiple logistics regression model to identify the factors independently associated with the response variable. The significance level adopted in the final model was of 0.05. Also in the final model, the variable of contact with the ground and the BMI status remained at a p-value of 0.025 and 0.030, respectively. An epidemiologically relevant prevalence of toxocariasis was found in the studied population. This prevalence serves as a warning sign that disease control measures need to be better publicized and implemented.Keywords: children; zoonoses; seroepidemiologic studies; toxocariasis RESUMOTem sido demostrada uma alta prevalência de toxocaríase em diferentes países do mundo, principalmente nos países tropicais. Dessa forma o objetivo desse estudo foi estimar a prevalência de toxocaríase e seus fatores associados em cem crianças de uma escola pública de Belo Horizonte, Brasil. Foram coletadas informações sociodemográficas, hábi-tos de estilo de vida, condições de saúde autorreferida, características relacionadas à moradia e à presença de animais domésticos. Também foram realizados exames clínicos, medidas antropométricas e exames laboratoriais (hemograma, IgG total, IgE total e ELISA para detecção de anticorpos IgG anti-Toxocara canis).
