This study aimed to determine the prevalence of dogs seropositive for Toxoplasma gondii and Neospora caninum (Apicomplexa) and the risk factors associated with seropositivity in the dog population of Ibiúna, São Paulo, Brazil. A total of 570 animals were examined in the 48 neighborhoods of the city from September 2007 to March 2008. Serological diagnosis of T. gondii and N. caninum infections was performed using indirect immunofluorescence assay (IFA), with endpoint titers of 1:64 for T. gondii and 1:50 for N. caninum. Of the 570 animals examined, 314 (55.1%; 95% CI = 50.9?59.2%) were seropositive for T. gondii and 40 (7.02%; 95% CI = 5.1?9.4%) for N. caninum. The variables presence of rodents (OR = 2.05), ingestion of raw meat (OR= 2.47), and prior sexual activity (OR = 1.79) were identified as risk factors for toxoplasmosis, whereas only prior sexual activity (OR = 3.29) was associated with an increased risk for neosporosis. Both T. gondii and N. caninum infections were detected by IFA in the dog population of Ibiúna. Rodent control and not feeding raw meat to dogs are important to reduce the risk of infection by T. gondii and N. caninum in the region.

Background: To identify geographical clusters of suicide in São Paulo, Brazil (2006–2015) and to verify the associations of suicide with sociocultural characteristics of its 96 districts. Methods: Spatial scan test was used to detect the geographical clusters. Correlation and multiple regression techniques were used to estimate the association of socioeconomic and cultural variables with suicide. Results: The mean suicide rate was 4.8/100,000. Three clusters were identified which are as follows: one of increased risk in downtown and two of decreased risk in the South and in the Southeast. The mean suicide rate of the high-risk clustered districts (7.99/100,000) presented significantly higher average incomes per household, higher proportion of formally educated, of no religious affiliation, of recent migrants, of all-times migrants and lower proportion of married. The multiple model selected two independent risk factors – people with no religious affiliation (β = 0.182) and of recent migrants (β = 0.278) – and two protective factors – the proportion of married (β = –0.185) and of total migrants (β = –0.075), which jointly explained 58.4% of the variance. Conclusion: Durkheimian social and cultural risk factors for suicide were confirmed. Compared to a previous study period (1996–2005), suicide rates and geographical clusters remained relatively stable in the subsequent decade (2006–2015).

OBJECTIVE: To assess risk factors for antepartum fetal deaths. METHODS: A population-based case-control study was carried out in the city of São Paulo from August 2000 to January 2001. Subjects were selected from a birth cohort from a linked birth and death certificate database. Cases were 164 antepartum fetal deaths and controls were drawn from a random sample of 313 births surviving at least 28 days. Information was collected from birth and death certificates, hospital records and home interviews. A hierarchical conceptual framework guided the logistic regression analysis. RESULTS: Statistically significant factors associated with antepartum fetal death were: mother without or recent marital union; mother's education under four years; mothers with previous low birth weight infant; mothers with hypertension, diabetes, bleeding during pregnancy; no or inadequate prenatal care; congenital malformation and intrauterine growth restriction. The highest population attributable fractions were for inadequacy of prenatal care (40%), hypertension (27%), intrauterine growth restriction (30%) and absence of a long-standing union (26%). CONCLUSIONS: Proximal biological risk factors are most important in antepartum fetal deaths. However, distal factors - mother's low education and marital status - are also significant. Improving access to and quality of prenatal care could have a large impact on fetal mortality.

The occurrence of Toxoplasma antibodies in domestic outpatient cats in the city of São Paulo was evaluated using the indirect immunofluorescence assay. A total of 248 blood samples obtained from male and female cats seen at the Veterinary Teaching Hospital at the University of São Paulo between February 1996 and January 1997 were tested. Of these, 17.7% were positive, with a 64 titer being detected in most animals. The frequence of Toxoplasma antibodies was significantly higher in older cats, those fed raw meat and those with free access to the outdoor environment. There was no significant difference in reactivity between males and females. We conclude that diet and free access to the outdoor environment were equally important as predisposing factors to the risk of Toxoplasma infection.

ABSTRACT: The occurrence of the black rat, Rattus rattus , in major Brazilian cities has increased in the recent years. To evaluate if the efforts of public rodent control have been reaching the species in the city of São Paulo, a survey was conducted in flooding areas using live trapping before and after implementation of the control program. Captures were carried out from 2009 to 2011, and animals were evaluated for their risk of zoonosis transmission. The number of R. rattus captured after control did not differ from the number of animals captured before the control program in the Spring/Summer season, but, in the Autumn/Winter season, effective control was observed. Low infestations of Ctenocephalides felis (Siphonaptera) and Echinolaelaps echidninus (Acarina) were observed, and antibodies against Leptospira spp. were detected in just 1 of 65 serum samples. Ten out of 18 serum samples were sororeactive for Vaccinia virus, suggesting contact between R. rattus and the pathogen Calodium hepaticum (= Capillaria hepaticum ) (Nematoda) was found in the liver of 73.4% of captured R. rattus. In conclusion, R. rattus may not be effectively controlled by the rodent Control Program in the city of São Paulo, and represents a threat to human health, justifying permanent environmental management and educational programs.
