Paramphistomidae em bovídeos em municípios no estado do Pará: Taxonomia e biologia molecular.

Abstract

Trematodes of the Paramphistomidae family, having been one of the great phases, considering the cattle, there is a high prevalence of these problems in the rumen and reticulum of these hosts in adults. bovids are currently bred in several regions of the world. In America, they are present in all countries with the exception of Chile and Canada. It has great prominence for Brazil. The Marajoara region presents great conditions for adaptation, in turn, it is a rustic animal which, in turn, is a non-parasitic rustic animal that, when it can present great damage to the animal's health as well as being free from damage to the animal's health. as well as free from harm to the health of the animal as well as to the breeders. One of the few reported examples that we have in scientific papers is the Paramphistomidae family present in the rumen and reticulum of bovids. Adult forms of the parasite are generally considered asymptomatic. Such forms have as infection site the portions of the rumen and reticulum of ruminants. Conversely, the immature forms have the small intestine as their predilection site and are responsible for paramphistomosis, a disease with an inflammatory reaction that culminates in diarrhea, causing serious damages. The present paper is justified for being relevant in the identification of the helminths responsible for the afore mentioned parasitosis, considering the lack of recent taxonomic identifications of Paramphitomidae sp, as well as suggesting their control. These are, therefore, relevant actions in order to avoid drops in production, and halt the transmission of these pathogens to other animals. Thus, this work aims to investigate the occurrence of Trematoda Digenea of the Paramphistomidae family in bovine animals from northeastern Pará on Pará State. Helminth samples were obtained from slaughterhouses in some municipalities in northeastern Pará and analyzed using light microscopy as well as scanning electron microscopy and DNA extraction with the polymerase chain reaction (PCR) and so, the taxonomic classification of the studied helminth was checked. Based on the analysis processing results, it is possible to infer that it is a new species of helminth of the Paramphistomidae family, genus Cotylophoron.
