Diplotriaena delirae Pinto & Noronha, 1970 is known to parasitize Pitangus sulphuratus (Linnaeus, 1766) in Peru and in the Midwestern and Southeastern regions of Brazil. Here, specimens of P. sulphuratus were collected in the southern state of Rio Grande do Sul, Brazil, and necropsied. Nematodes (n = 6) found in these specimens were identified as D. delirae based on their morphological traits. This is the first report of D. delirae from southern Brazil, expanding the knowledge of the helminth fauna of P. sulphuratus in the Neotropical region.

Astyanax Fasciatus

Dendrorchis retrobiloba Volonterio & Ponce de León, 2005 was first described from the swim bladder of Astyanax fasciatus (Cuvier, 1819) from Montevideo, Uruguay. In this study, we necropsied specimens of A. aff. fasciatus collected from Lake Guaíba, in Rio Grande do Sul, Brazil, for the analysis of their helminths. The digeneans were identified as D. retrobiloba by their elongated body, oral sucker longer than ventral sucker, and 2 posterior lobes. This is the first report of D. retrobiloba in A. aff. fasciatus from Lake Guaíba and extends the known geographic distribution of this parasite.

Abstract Up until now, there have been few studies of the helminth fauna of Brazilian populations of Pogonias cromis. In North America, P. cromis is known to be a definitive host of Cotylogaster basiri, although there have been no reports of any species of Cotylogaster infecting fish in Brazil. During necropsies of marine fish obtained from professional fisherman in the state of Rio Grande do Sul, Brazil, specimens of C. basiri were found in the intestine and rectum of P. cromis. In comparison with previous studies, differences were found in relation to the number of lobes in the buccal disc and the development of the biocellate larvae in the eggs of C. basiri. This is the first report of C. basiri in P. cromis from Brazil, contributing to the understanding of the helminth fauna of this fish from the coastal zone of Brazil.

Rio Grande do Sul is the southern state of Brazil and includes 569 taxa of bryophytes, a rich diversity promoted by its geographical position. All recent floristic inventories in the state recorded new occurrences of species, indicating that the diversity of bryophytes may be underestimated. Through floristic inventories carried out between 2016 and 2019, new occurrences of 16 species, included in seven families and 11 genera, were identified. Seven of them are also new records for the Southern Brazil. Bryophyta is represented by five species, four genera and four families, and Marchantiophyta by 11 species, seven genera, and three families.

Prior to the present study, Nematomystes scapteromi (Ganzorig, Oku, Okamoto, Malgor & Kamiya, 1999) Jiménez-Ruiz & Gardner, 2003 had been reported in Scapteromys tumidus Waterhouse, 1837 from Uruguay. Here, eight specimens of S. tumidus were collected in southern Brazil and necropsied. The nematodes encountered were determined as N. scapteromi through their morphometric traits. Prevalence was 87.5% and the mean intensity of infection of 18.3 helminths/host. This is the first report of N. scapteromi parasitizing S. tumidus in the state of Rio Grande do Sul, Brazil.

The species Amblyomma longirostre Koch, 1844 is poorly known in the state of Rio Grande do Sul. Usually the adult stage could be found on Sphigurus spp. and the immatures on birds (Passeriformes). Although A. longirostre is distributed in the Neotropical region, from Panama to Uruguay, it also occurs in Central America and the United States. The aim of this study was to report that Ramphastos dicolorus Linnaeus 1766 is a new host record for this tick species.

ABSTRACT: Protozoal diseases caused by species of Sarcocystiscan cause serious damage in sheep flocks, inducing decreased growth conversion rates and partial or complete loss of carcasses at the slaughterhouse. This article describes an outbreak of Sarcocystis giganteainfection in sheep slaughtered in a farm in Rio Grande do Sul State, Brazil. Between July and September 2013, three sheep showed multiple nodules in the esophagus that were microscopically characterized as encapsulated cysts filled with elongated, basophilic, nucleated structures morphologically consistent with S. giganteabradyzoites. Diagnosis was made based on the epidemiological, macroscopic, and microscopic findings. This is the first report of this infection in sheep in Rio Grande do Sul and should be recognized by veterinarians, especially during meat inspection.

Abstract Birds act as hosts for a variety of parasites, many of these are unreported. The literature provides scant information on the helminth fauna of Phimosus infuscatus. The presence of helminths were investigate in 28 birds from Pelotas, Capão do Leão, and Rio Grande in Rio Grande do Sul. The preparation and identification of helminths followed protocols. Prevalence (P%), mean intensity of infection (MII), and mean abundance (MA) were estimated. The following helminths were found: Hystrichis acanthocephalicus , Dioctophyme renale (larva), Porrocaecum heteropterum , Baruscapillaria sp., Aproctella carinii , Paradeletrocephalus minor, and Cyathostoma sp. (Nematoda); Echinostomatidae gen. sp., Tanaisia valida, and Athesmia sp. (Trematoda: Digenea) and Megalacanthus sp. (Cestoda). The most prevalent species were H. acanthocephalicus, P. heteropterum, Megalacanthus sp., and Echinostomatidae gen. sp. and Megalacanthus sp. had the highest MII and MA. There was a significant difference in the prevalence of H. acantocephalicus between female and male bird hosts. We report Echinostomatidae gen. sp., T. valida, Athesmia sp., Cyathostoma sp., A. carinii, P. minor, D. renale (larva), Baruscapillaria sp., and Megalacanthus sp. for the first time in P. infuscatus in Brazil.

We report the finding of Amblyomma aureolatum (Acari: Ixodidae) parasitizing margay (Leopardus wiedii) in the locality of Gravataí (29º 47' 12.9'' S and 50º 53' 44.1'' W; 241 m alt.), State of Rio Grande do Sul, Southern Brazil. This is the first report of this species of Ixodidae on margay in Southern Brazil. This finding indicates an increased number of hosts for this tick species.

Guerrerostrongylus zetta had been found in a number of different species of rodents from northern and southeastern Brazil as well as Argentina. Between 2008 and 2010, specimens of Oligoryzomys nigripes (n = 14) were collected and necropsied. The nematodes encountered were identified as G. zetta due their morphological traits. Prevalence was 78%, with a mean intensity of infection of 5.63 helminths/host. This report fills in a lacuna in the known distribution of G. zetta, and provides the first record of this parasite in the state of Rio Grande do Sul, Brazil.
