| antibody response to newcastle disease vaccination in a flock of young partridges (rhynchotus rufescens). | ten young partridges (rhynchotus rufescens) were vaccinated with the lentogenic strain of newcastle disease virus. another eight unvaccinated birds were kept in close contact with the treated flock. antibodies levels were measured over the course of 3 mo in all birds using the hemagglutination inhibition (hi) test and the liquid-phase blocking enzyme-linked immunosorbent assay (lpb-elisa). the lpb-elisa was standardized, and the results were compared with those obtained with the hi test. antibod ... | 1999 | 10572878 |
| first isolation of an h1n1 avian influenza virus from wild terrestrial non-migratory birds in argentina. | a type a avian influenza (ai) virus was isolated from dead or severely ill red-winged tinamous (rhynchotus rufescens) found in a hunting ground in april 2008 in argentina. the subtype of a/red-winged tinamou/argentina/mp1/2008 was determined as h1n1 by sequence analysis. the cleavage site of the viral hemagglutinin corresponded to a low pathogenic influenza virus, although the clinical presentation and pathological studies suggest that the virus was pathogenic for red-winged tinamous. phylogenet ... | 2010 | 19896684 |
| A new quill mite species (Acari: Syringophilidae) parasitising tinamous (Aves: Tinamiformes). | Tinamiphilopsis ariconte n. sp., a syringophilid mite, is described from three tinamou species (Tinamidae), Rhynchotus rufescens (Temminck) and Nothura boraquira (Spix) in Paraguay and N. minor (Spix) in Brazil. These data indirectly support the hypothesis that the cheyletoid-like predatory ancestor of the Syringophilidae switched to parasitism before the divergence of the avian hosts into the two major clades Palaeognathae and Neognathae. | 2012 | 22183920 |
| feasibility of semen collection in red-winged tinamou (rhynchotus rufescens) by manual stimulation and sazonality implications. | this study aimed to report in detail, the technique and challenges of cloacal massage, to collect and evaluate semen from red-winged tinamou (rhynchotus rufescens) keep in captivity, performed by only one technician. sixty-four semen collection attempts, from 16 adult males, during breeding season and 16 attempts form these same 16 males in non-breeding season, were performed. prior to collection, all animals were conditioned to cloacal massage for 6 weeks and the ejaculates were succeed with vi ... | 2018 | 29128699 |
| genetic parameters for tonic immobility, body weight, and morphological traits of the red-winged tinamou (rhynchotus rufescens). | this study was carried out to estimate genetic parameters for morphology, body weight, and tonic immobility traits in the red-winged tinamou (rhynchotus rufescens). information on 690 birds was used and genetic parameters were estimated using bayesian methods under a multi-trait animal model. the following traits were considered in this study: tarsal length (tl), bill length (bl), wing length (wl), head width (hw), bill width (bw), mature weight (mw), weight at 90 days (w90), and tonic immobilit ... | 2020 | 31313019 |
| a new, major c27 biliary bile acid in the red-winged tinamou (rhynchotus rufescens):25r-1beta, 3alpha,7alpha-trihydroxy-5beta-cholestan-27-oic acid. | the chemical structures of the three major bile acids present in the gallbladder bile of the red-winged tinamou (rhynchotus rufescens), an early evolving, ground-living bird related to ratites, were determined. bile acids were isolated by preparative reversed-phase hplc. two of the compounds were identified as the taurine n-acylamidates of 25r-3alpha,7alpha-dihydroxy-5beta-cholestan-27-oic acid (constituting 22% of biliary bile acids) and 25r-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-27-o ... | 2009 | 19011113 |
| isolation and characterization of ten novel microsatellite loci in the red-winged tinamou (rhynchotus rufescens, tinamiformes, aves) and cross-amplification in other tinamous. | we describe the isolation and characterization of ten microsatellite loci from the red-winged tinamou (rhynchotus rufescens) and also evaluated the cross-amplification of these loci and other ten loci previously developed for the great tinamou (tinamus major) in other tinamous. genetic variability was assessed using 24 individuals. six loci were polymorphic with moderate to high number of alleles per locus (2-12 alleles) and showed expected heterozygosity (he) ranging from 0.267 to 0.860. all lo ... | 2012 | 21947952 |
| a new feather mite species of the genus neumannella trouessart, 1916 (analgoidea, dermoglyphidae) from the red-winged tinamou rhynchotus rufescens (temminck, 1815) (aves, tinamiformes) with remarks to the evolution of host-parasite associations of the genus. | neumannella skorackii, a new species of the feather mite family dermoglyphidae (acari, astigmata) is described from the red-winged tinamou rhynchotus rufescens (temminck, 1815) (aves, tinamiformes) from paraguay and a key to all known species of the genus is provided. the phylogenetic relationships (mp analysis of 25 morphological characters) between neumannella species along with the evolutionary history of host-parasite associations revealed by jungle reconciliation method are reconstructed. r ... | 2014 | 24827087 |
| [an outbreak of coccidiosis in partridge (rhynchotus rufescens), reared in captivity, by eimeria rhynchoti reis and nobrega, 1936 (apicomplexa: emeriidae)]. | eimeria rhynchoti is redescribed parasitizing partridge (rhynchotus rufescens), reared in captivity, from jaboticabal city, são paulo state, brazil. sporulation takes place in 48 hours, the shape of oocysts found vary from spherical to elliptic with 23.01 micro +/- 1.57 of length by 21.0 micro +/- 1.78 of width. the microple, polar cap and residuum of the oocysts were absent. the oocyst wall, measures 2.2 micro +/- 0.31 of thickness, is composed by two smooth layers; the polar granule is present ... | 2007 | 16834902 |
