Com o objetivo de avaliar a ocorrência da infecção por Toxoplasma gondii, em ovinos das regiões periurbana e urbana do município de Curitiba, Paraná, Região Sul do Brasil, foram coletadas amostras de sangue de 167 ovinos, de três rebanhos. O teste de ELISA foi utilizado para detectar anticorpos anti-Toxoplasma gondii. Dos 167 soros ovinos, 43 (25,75%) apresentaram anticorpos anti-T. gondii. O parasito está difundido entre os ovinos das duas regiões estudadas.This study evaluated occurrence of the Toxoplasma gondii infection in ovine from urban and periurban areas of Curitiba, State of Paraná, Southern of Brazil. Blood samples from 167 sheep from three farms were collected. ELISA assay was used to detect IgG anti-Toxoplasma gondii antibodies. Of 167 ovine samples, 43 (25.75%) were positive. The parasite is widespread among sheep from urban and periurban areas of Curitiba.

We used a structured approach to assess whether active smokers presented with pictorial warnings on cigarette packages (PWCP) had a higher probability of quitting, reducing, and attempting to quit smoking than did unexposed smokers. We identified 21 articles from among nearly 2500 published between 1993 and 2013, prioritizing coverage over relevance or quality because we expected to find only a few studies with behavioral outcomes. We found very large heterogeneity across studies, poor or very poor methodological quality, and generally null or conflicting findings for any explored outcome. The evidence for or against the use of PWCP is insufficient, suggesting that any effect of PWCP on behavior would be modest. Determining the single impact of PWCP on behavior requires studies with strong methodological designs and longer follow-up periods.
