Risk factors associated with serological Salmonella prevalence in finishing pig herds in southern Brazil

AbstractThis study investigated the epidemiological factors that contribute to the seroprevalence of Toxoplasma gondii and Toxocara spp. in children from Paraná state, Brazil. Immunoglobulin G (IgG) antibodies to T. gondii were detected using indirect immunofluorescence, and IgG antibodies to Toxocara were detected using an enzyme-linked immunosorbent assay. For each individual, a questionnaire was completed that contained epidemiological and clinical data. The data analysis was performed using multiple logistic regression. Of the 544 children investigated, 3.2% presented co-infection with T. gondii and Toxocara spp. Of this total, 7.4% were positive for antibodies to T. gondii, and 25% were positive for antibodies to Toxocara spp. The presence of antibodies to Toxocara spp. increased the risk of T. gondii infection (P= 0.029). Children who were 1–8 years of age were less infected by T. gondii than those who were 9–12 years of age. The variables that influenced positivity for anti-Toxocara spp. were the origin of the children and contact with sand. Children with positive serology for Toxocara spp. presented more eosinophilia compared with those with non-reactive serology. Infection with both parasites reveals the need for preventive measures, such as guidance about modes of infection, parasite control and monitoring recreational areas.

Sera were collected from 300 domiciled cats from the municipality of Lages, Southern Brazil, to determine the prevalence of Toxoplasma gondii antibodies and risk factors associated. Tests for T. gondii antibodies were performed using indirect immunoﬂuorescent antibody test (IFAT). Positive reactions with titers >1:64 were found in 43 (14.33%) cats. A significant number of seropositive cats were >6 month old (p = 0.03758) and had access to the streets or/and rural areas (p = 0.04185). The results indicate that T. gondii is widespread in cats in Lages with a prevalence of 14.33%.

AbstractToxoplasmosis causes complications during pregnancy that have serious effects on fetal development. Thus far, toxocariasis has been reported to spread only via vertical transmission. Nonetheless, the population of pregnant women is also exposed to this infection. Co-infection with both Toxoplasma gondii and Toxocara spp. has been reported in children, but there are no reports of co-infection in the population of pregnant women. The aim of this study was to determine the prevalence of co-infection with T. gondii and Toxocara spp. in pregnant women at a university hospital in southern Brazil, and to identify the risk factors associated with infection by both parasites. Two hundred pregnant women were tested for the presence of anti-T. gondii and anti-Toxocara spp. antibodies and were asked to complete an epidemiological questionnaire. In this study, the co-infection rate observed in the total population of pregnant women was 8%. In addition, women with a positive result for a serology test for Toxocara spp. were at increased risk of infection by T. gondii (P = 0.019). Co-infection with both parasites in pregnant women was associated with low birth weights in neonates. The similar modes of transmission of both parasites could explain the co-infection. Only a few previous studies have investigated this phenomenon. The findings of the present study emphasize the importance of serological diagnosis during prenatal care and further research in this area to identify risk factors associated with this co-infection, and the possible implications of this co-infection during pregnancy and on the health of newborns.

The frequently asymptomatic sexually transmitted infections (STIs) caused by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) are poorly diagnosed in Brazil and can lead to severe complications/sequelae without timely detection and treatment. We investigated prevalence of CT, NG, and MG infections and associated demographic, behavioral, and clinical factors in consecutive women attending a gynecology and obstetrics outpatient clinic in Pelotas, Southern Brazil. Vaginal swab samples were prospectively obtained from asymptomatic and symptomatic women (n = 498) from August 2015 to December 2016 and tested with Aptima Combo2 and Aptima M. genitalium assays (Hologic). The prevalence of CT, NG, and MG was 6.8% (34/498), 1.0% (5/498), and 4.2% (21/498), respectively. Three (0.6%) cases of CT and NG co-infection and one (0.2%) case of CT and MG co-infection were identified. The risk factors associated with these bacterial STIs were youth (<30 years), no steady sexual partner, infection with additional STI, and lack of income. Bacterial STIs, particularly CT and MG, were prevalent among women, including pregnant women (60% of positive cases), in Pelotas, Brazil. Sensitive and specific diagnostic testing and early treatment are essential to control STIs, limit transmission chains, avoid future complications/sequelae, and reduce health and cost burdens on the population.

OBJECTIVE To analyze the factors associated with a lack of prenatal care in a large municipality in southern Brazil. METHODS In this case-control age-matched study, 716 women were evaluated; of these, 179 did not receive prenatal care and 537 received prenatal care (controls). These women were identified using the Sistema Nacional de Informação sobre Nascidos Vivos (Live Birth Information System) of Pelotas, RS, Southern Brazil, between 2009 and 2010. Multivariate analysis was performed using conditional logistic regression to estimate the odds ratios (OR). RESULTS In the final model, the variables associated with a lack of prenatal care were the level of education, particularly when it was lesser than four years [OR 4.46; 95% confidence interval (CI) 1.92;10.36], being single (OR 3.61; 95%CI 1.85;7.04), and multiparity (OR 2.89; 95%CI 1.72;4.85). The prevalence of a lack of prenatal care among administrative regions varied between 0.7% and 3.9%. CONCLUSIONS The risk factors identified must be considered when planning actions for the inclusion of women in prenatal care by both the central management and healthcare teams. These indicated the municipal areas with greater deficits in prenatal care. The reorganization of the actions to identify women with risk factors in the community can be considered to be a starting point of this process. In addition, the integration of the activities of local programs that target the mother and child is essential to constantly identify pregnant women without prenatal care.
