Environmental contamination by parasite forms was studied on a university campus in the municipality of Pelotas, Rio Grande do Sul. Soil samples were analyzed using the modified Caldwell & Caldwell technique to identify parasite forms. Nematode eggs were detected in 62% of the samples. Among the parasites detected, eggs of Toxocara spp. and Ancylostomatidae(More)
The close contact between dogs and humans poses a high risk of exposure to Toxocara canis eggs, which can lead to Visceral Larva Migrans (VLM) syndrome. The objective of this study was to investigate the existence of these nematode eggs on the hair of the perianal region in stray and owned dogs. Samples of hair from 104 dogs of different ages were(More)
Forty wild canids were captured by live trap at Municipalities of Pedro Osorio and Pelotas in Southern of the State of Rio Grande do Sul and they were transported to the Parasitology Laboratory at the Universidade Federal de Pelotas. After they were posted, segments of intestinal, respiratory and urinary tracts and liver were separated and examined. Animal(More)
Anti-Trypanosoma cruzi antibodies in the umbilical cord of 351 parturients in the city of Pelotas, Rio Grande do Sul were investigated to determine the prevalence of Chagas disease among pregnant women. One case was identified (0.3%), without detection of congenital transmission. This highlights the importance of investigating Chagas disease among pregnant(More)
Human and animal leptospirosis caused by Leptospira spp. belonging to serogroup Ballum has increased worldwide in the past decade. We report the isolation and serologic and molecular characterization of four L. borgpetersenii serogroup Ballum isolates obtained from Mus musculus, and preliminary virulence studies. These isolates are useful for diagnosis of(More)
Lagochilascariasis, a parasitic disease little known in Brazil, is caused by an ascarid nematode that has a peculiar life cycle, with a predilection site for the cervical region in the final hosts: humans, cats and dogs. We aimed to record the occurrence of Lagochilascaris minor in domestic cats from rural areas in the Municipality of Pelotas, Rio Grande do(More)
Efficient control of gastrointestinal parasites is necessary in sheep breeding. However, the available chemically based anthelmintics are becoming less effective due to the development of parasite resistance. An alternative to this problem is biological control. In the present study, we tested the larvicidal effect of Bacillus circulans by administering a(More)
Visceral toxocariasis is a neglected parasitic zoonosis that occurs through the ingestion of embryonated Toxocara spp. eggs. A wide range of animal species can act as paratenic hosts for this ascarid. The main risk factor for humans is the ingestion of the eggs from contaminated soil; however, infection can also occur through the ingestion of contaminated(More)
Public parks, especially in developing countries, are places where stray animals run free and may contaminate the environment with different species of parasites. In an evaluation of environmental sanitation of these sites, soil samples were collected monthly from public parks in the Pelotas city, Rio Grande do Sul State, Southern Brazil. Eggs of the(More)
