RESUMO
Coproparasitological analyses were performed on 191 daycare children and 434 elementary school children from urban and rural areas in Rolândia, Parana State, Brazil. The overall prevalence of enteroparasites was 15.2 % for daycare children and 52.5% for elementary school children. Risk factors are discussed.

Three hundred and seventy serum samples collected from ovine herds in Londrina, Parana State, were tested by indirect immunofluorescence for Toxoplasma gondii. The overal percentage of reagents (>=1:64) was 47.83 per cent. There were no significant differences amongst age groups. The percentage of reagents was: 48.55 per cent amongst ewes, 36.84 per cent amongst rams, 47.37 per cent amongst ram lambs and 48.31 per cent amongst lambs. Is was concluded that T. gondii infection is highly pervalent in ovine herds of Londrina region

The aim of this study was to determine the resistance of Toxoplasma gondii cysts to salt (sodium chloride) and condiments (black pepper and garlic) in fresh sausages prepared with experimentally infected pork. The sausages were treated with 1.25, 2.00, and 2.50% salt with condiments added, and were refrigerated for 2, 24, and 48 hours, after which they were artificially digested. Mice were then inoculated with the digested matter. After 42 days the surviving mice were sacrificed and their serum examined using indirect immunofluorescence to detect anti-T. gondii antibodies. This examination showed that the treatments with salt over periods of less than 24 hours did not eliminate the parasite, and that only after 48 hours did the salt, at concentrations of 2.00 and 2.50%, effectively kill the parasite. The results of this experiment also showed that the condiments had no effect on the viability of T. gondii.
