Parasitos gastrointestinais de suínos criados em uma granja em Nova Iguaçu, Rio de Janeiro

At the national level, there are several types of pig breeding that employ diversified technologies and management, depending on the financial conditions of each producer. This difference, evidenced in the productions, ends up reflecting the presence of infectious agents in animals, including infections determined by gastrointestinal parasites such as helminths and protozoa. Due to the lack of information and the importance of this topic, this study aimed to report, through a parasitological survey, the frequency of gastrointestinal parasites detected in pig raised on a farm located in the Nova Iguaçú city, Rio de Janeiro. For this purpose, 200 fecal samples from 40 pens were collected. Fecal samples were processed in a pool using the Lutz spontaneous sedimentation technique. In 100% of the samples, forms of parasites were detected, being mainly strongyles eggs (97.5%), followed by coccidia oocysts (87.5%), Balantioides coli cysts (75%), Strongyloides ransomi eggs (42.5%), Ascaris suum (25%) eggs and Trichuris suis (7.5%), with statistically significant differences between these frequencies. From the parasitological survey carried out, it was possible to identify a high frequency of parasites in the fecal samples of the animals, confirming that the pig farm had precarious conditions for sanitary management.

Debido a la falta de información y la importancia del tema, este estudio tuvo como objetivo informar, a través de una pesquisa parasitológica, la frecuencia de los parásitos gastrointestinales detectados en las heces de cerdo mantenidas en una granja ubicada en el municipio de Nova Iguaçú-RJ. Para este propósito, se recolectaron 200 muestras fecales de 40 puestos. Las muestras fecales se procesaron en pool utilizando la técnica de sedimentación espontánea de Lutz. En el 100% de las muestras, se detectaron formas evolutivas de parásitos, principalmente huevos de strongyles eggs (97.5%), seguidos de oocistos de coccidio (87.5%), quistes de Balantioides coli (75%) huevos de larvas de Strongyloides ransomi (42.5%), huevos de Ascaris suum (25%) y Trichuris suis (7.5%), con diferenci
