The increase of canine population in urban areas, which englobes stray or domiciled dogs, has an important epidemiological role in soil contamination of public areas. This increase contributes for the dissemination of infections by parasites via faeces of infected animals. The aim of this study was to detect the presence of immature forms of gastrointestinal parasites of mammals in soil from public roads and squares of the municipality of Garanhuns, state of Pernambuco, Brazil. A total of 211 soil samples were obtained and evaluated through the Faust and Rugai techniques. Out of 211 soil samples, 49.29% (104/211) scored positive the presence of immature forms of gastrointestinal parasites of mammals, being Ancylostoma sp. (37.91%) the most frequent. In conclusion, the soil of different parts of the municipality of Garanhuns is contamined by parasites of medical and veterinary concern. Therefore, the implementing of integrated prophylaxis measures is necessary to prevent the soil contamination, reducing the risk of infection for humans.

Introduction: The present study aimed to assess the seroprevalence and spatial distribution of Neospora caninum and Toxoplasma gondii in dogs. Methods: Blood samples (n = 241) were collected and analyzed for the presence of anti-N. caninum and anti-T. gondii antibodies. The spatial distribution was evaluated using kernel density estimation (KDE). Results: Anti-N. caninum and anti-T. gondii antibodies were detected in 24.06% (58/241) and 9.54% (23/241) of samples, respectively. A heterogeneous spatial distribution of positive dogs was observed across the city. Conclusions: These data are pivotal for better understanding the dynamics of infection caused by these protozoa in the canine population.

The purpose of this trial was to evaluate serum levels of oxidative stress biomarkers and biochemical analytes in crossbred lambs during the rearing phase in an integrated crop-livestock system (ICLS) to control gastrointestinal parasites. The experiment used 36 crossbred lambs (cross: Ile de France × White Dorper × Texel) divided into two groups. The WCS group was supplemented with whole cottonseed (WCS), and controls had no supplementation. Body weight, blood collection, and fecal analysis of nematode eggs and Eimeria oocysts counting per gram of feces were performed for each animal within 84 days of experiment. The following serum analytes were determined: total protein, albumin, globulin, cholesterol, haptoglobin, and 10 oxidative stress biomarkers: cupric reducing antioxidant capacity, ferric reducing ability of plasma, trolox equivalent antioxidant capacity, thiol, uric acid, paraoxonase-1, total oxidant status, ferric-xylenol orange, advanced oxidation protein products, and reactive oxygen metabolites derived compounds. The inclusion of WCS suggested the benefit in controlling infection as well as inducing an increase in antioxidants and a decrease in oxidants in lambs naturally infected by gastrointestinal parasites. The combination of WCS and ICLS could be a useful tool in controlling gastrointestinal parasite infection without affecting the production performance.
