Most parasites represent a serious socioeconomic problem, because they affect pets, commercially raised, wild, and zoonotic animals. Weight loss, growth retardation, predisposition to other diseases and death are symptoms presented by the parasitized animals. The aim of this study was to evaluate the helminth fauna in bull-frog Lithobates catesbeianus raised for sale. We worked with five frog farms in the Vale do Paraíba, São Paulo, Brazil, and examined a total of 185 animals. The autopsies were performed, and all bodies that may have parasites were examined. Diagnostic parasitology tests were also performed. We found one species of nematode, Longibucca catesbeianae, with a prevalence of 1.7%, mean abundance of 14.16 and an average intensity of 850 (with a range of 729 to 1014). Given that most studies of parasitology in amphibians is conducted in free-living animals, more research on ...

The sheep farming mainly in the southern region of Brazil. In Paraná State the production is mainly performed in small areas with large capacity of animals, favoring the contamination of pastures and the infection of animals by gastrointestinal parasites that mostly present quickly spread. The small breeding, mostly found in this region, do not follow standards of breeding sheep, however, it was observed a higher prevalence of sheep breeding woolless, probably due to the weather favorable to the creation of these animals. In this study performed in the northwest of Paraná State, samples were randomly collected in 87 animals from five different properties. In each property was collected 30% of each category stipulated in the flock: one to three months, three to six months, six months dose, and animals over one year of age. After collecttion the feces were sent to the Laboratory of Veter...

The occurrence of endoparasitoses in domestic animals has been reported routinely in the medical clinic of small animals, where wandering and domiciled cats are considered important reservoirs, evidencing the role of felines in the contamination of the environment by the infective forms of these parasites. Many animals are asymptomatic, but those with high parasitic load evidence clinical signs such as inappetence, anorexia, vomiting and diarrhea. The present study aimed to identify the different parasites found in faecal samples of semi - domed felines; for this, 45 fecal samples of cats were collected, regardless of age, sex or race, from different households in the municipality of Maringá, PR, Brazil. The collected samples were submitted to coproparasitological tests by means of the Willis & Mollay flotation method, carried out in the Veterinary Parasitology laboratory of the Veterin...
