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.

The two endemic, endangered species, Bacch­aris hypericifolia (Asteraceae) and Hypericum salvadorense (Hypericaceae), were known only for the Rio Grande do Sul state, in Brazil. In this paper we report two new occurrences of these species in Santa Catarina, expanding their geographic distribution to the north. Baccharis hypericyfolia and H. salvadorense were collected in areas of PPBio (Programa de Pesquisa em Biodiversidade) project. These novelties evidence the presence of knowledge gaps regarding the flora and little collecting effort in the grasslands from Southern Brazil.

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.

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.

First Occurrence

A total of 81 Tyraniidae birds were examined, 80 Pitangus sulphuratus (Linnaeus, 1766) (Great kiscadee), and one Machetornis rixosa (Vieilot, 1819) (Cattle tyrant), for collection of nasal mites, which were identified as Ptilonyssus spinosus (Brooks & Strandtmann, 1960) and Sternostoma longisetosae (Hyland, 1961) (Rhinonyssidae). This finding characterises the first report of P. spinosus and S. longisetosae in P. sulphuratus, and the first record of P. spinosus in M. rixosa, and expands the geographic distribution of these species. It is the first occurrence of S. longisetosae in the Neotropics, and the first citation of P. spinosus in the state of Rio Grande do Sul, Brazil.

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.
