The new taxon differs from S. bayagbonai and S. singhi congeneric species from the Gulf of Guinea and Indian Ocean respectively, mainly in the body size, the structure of the reproductive system, the development of the ecsoma and the sinus sac. It differs from the first one mainly in the presence of two frontal protuberances at the level of the preoral lobe, which are absent in the specimens studied here. Also in general terms, S. bayagbonai is comprised of slightly larger individuals, with larger pharynx, testicles and ovary. And it differs from S. singhi by their smaller duct and hermaphroditic sac and for having a well developed seminal receptacle, which is absent in the Bay of Bengal specimens. When comparing the relative size of the ecsoma, we found significant differences among both of the populations of digeneans examined, the worms collected in the Parana River was more developed than those from the Bahia Blanca estuary. The host, L. grossidens, migrates to the Parana river in winter and spring and then, from December to March it makes a trophic migration towards the sea and is found all along the Atlantic coast of Buenos Aires province. For this reason, it is here hypothesized that the relative development of the tail, is affected by environmental conditions, such as pH and osmolarity of the stomach, salinity and/or water temperature.","PeriodicalId":328487,"journal":{"name":"Neotropical helminthology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133356955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For its high commercial value and overfishing, the Arapaima has a risk of extinction. For this reason, it is attractive for fish farming, apart from having a good zoo-technical performance. One of the most serious problems to its production in cultivation is the parasitic diseases which intervene in the quantity and quality of fish. The endoparasites such as nematodes feed on nutrients already processed by the host and can cause intestinal disorder, bringing the fish malnutrition and a state of anemia. In the present study, the histopathological changes caused in the gut of A. gigas by the nematode Spirocamallanus inopinatus (Travassos, 1929) were analyzed. The intestines of six specimens of which three hosts were parasitized by nematodes were histological processed. The following changes were found: focal areas of necrosis, desquamation, inflammatory infiltrate, cytolysis and formation of fibrous capsules.

D. pacupeva and S. oxydoras had their abundances influenced by the host's gonadal maturity stage.

Strongyle eggs were found in 553 horses, Parascaris equorum eggs in 69 specimens, and Oxyurus equi in 8. A total of 264 specimens were negative. The highest percentage of parasites observed was 62% Strongyles, 8% P. equorum, Oxyurus equi 1% and 30% were negative for the presence of parasite eggs. The presence of equine infected with strongyles remained within the range of 600-1900 HPG, while in P. equorum, HPG was 350-800 and O. equi had a mean of 400 HPG.
