Chromosomal similarity between the Scaly-headed parrot (Pionus maximiliani), the Short-tailed parrot (Graydidascalus brachyurus) and the Yellow-faced parrot (Salvatoria xanthops) (Psittaciformes: Aves): a cytotaxonomic analysis
Provedor de dados: 74
Autores: Caparroz,Renato; Duarte,José Maurício Barbanti.
Behavior, morphology, allozyme studies and DNA hybridization and sequencing data all suggest the independent evolution of the Old and New World parrots and support tribe status for the American species, although the phylogenetic relationships within this tribe are still poorly understood. A previous study has shown that the Yellow-faced parrot (Amazona xanthops Spix 1824) exhibits large karyotypic differences compared to the other Amazona species and suggested that this species should be renamed Salvatoria xanthops, although the relationships between S. xanthops and the other New World parrots remain unclear. In the present work, we describe the karyotype of the Scaly-headed parrot (Pionus maximiliani, Kuhl 1820) and the karyotype and C-banding pattern of...

Comparative analysis of microsatellite variability in five macaw species (Psittaciformes, Psittacidae): application for conservation
Provedor de dados: 74
Autores: Presti,Flavia T.; Oliveira-Marques,Adriana R.; Caparroz,Renato; Biondo,Cibele; Miyaki,Cristina Y.
Cross-amplification was tested and variability in microsatellite primers (designed for Neotropical parrots) compared, in five macaw species, viz., three endangered blue macaws (Cyanopsitta spixii [extinct in the wild], Anodorhynchus leari [endangered] and Anodorhynchus hyacinthinus [vulnerable]), and two unthreatened red macaws (Ara chloropterus and Ara macao). Among the primers tested, 84.6% successfully amplified products in C. spixii, 83.3% in A. leari, 76.4% in A. hyacinthinus, 78.6% in A. chloropterus and 71.4% in A. macao. The mean expected heterozygosity estimated for each species, and based on loci analyzed in all the five, ranged from 0.33 (A. hyacinthinus) to 0.85 (A. macao). As expected, the results revealed lower levels of genetic variability...

Karyotype description of two Neotropical Psittacidae species: the endangered Hyacinth Macaw, Anodorhynchus hyacinthinus, and the Hawk-headed Parrot, Deroptyus accipitrinus (Psittaciformes: Aves), and its significance for conservation plans
Provedor de dados: 74
Autores: Lunardi,Vitor de Oliveira; Francisco,Mercival Roberto; Rocha,Guaracy Tadeu; Goldschmidt,Beatriz; Galetti Junior,Pedro Manoel.
Neotropical parrots are among the most threatened groups of birds in the world, and many species are facing extinction in a near future. At the same time, the taxonomic position of many species remains unclear. Karyotype analysis has been used to elucidate the phylogenetic status of many bird groups, also providing important information for both in situ and ex situ conservation plans. The objective of the present study was to describe for the first time the karyotypes of the endangered Hyacinth Macaw, Anodorhynchus hyacinthinus, and of the Hawk-headed Parrot, Deroptyus accipitrinus. A diploid number of 2n = 70 and a karyotype similar to the main pattern previously found for the genera Ara, Cyanopsitta, Aratinga, Propyrrhura, Pionites, Pionopsitta,...

The karyotype of the critically endangered Lear's macaw, Anodorhynchus leari Bonaparte 1856 (Aves, Psittaciformes)
Provedor de dados: 74
Autores: Nogueira,Denise Monnerat; Souza,Lucia Moreno de; Goldschmidt,Beatriz; Silva,Christiano Pinheiro da; Monsores,Denise Wilches.
We used conventional chromosomal staining to describe the karyotype of the critically endangered Lear's macaw, Anodorhynchus leari Bonaparte 1856. A diploid number of 2n = 70 and a karyotype similar to that of its congener Anodorhynchus hyacinthinus suggests that chromosomal rearrangements were not the main evolutionary mechanism in the genus.

Provedor de dados: 89
Autores: Gomes,AM; Costa,LL; Vilela,DAR; Marques,MVR; Carvalhaes,AG; Marin,SY; Costa,MP; Horta,RS; Resende,JS; Martins,NRS.
Mycoplasma gallisepticum (Mg) infection of wild native Brazilian psittacines (Psittaciformes) which died of any cause during sorting, rehabilitation, or conservation, was investigated by PCR. Two previously described PCR methodologies using Mg specific primers were employed for the analyses of 140 swab samples (cloaca, trachea, or palatine cleft). Average positive Mg detection in cloacal swabs was 51.9%, with 80.0% (n=5) of Blue-and-yellow Macaws (Ara ararauna), 60.0% (n=3) Dusky Parrots (Pionus fuscus), 52.5% (n=59) Amazon Parrots (Amazona aestiva), 50.0% (n=2) Orange-winged Parrots (Amazona amazonica), 50.0% (n=2) Jandaya Parakeetsor Jandaya Conures (Aratinga jandaya), 0% (n=2) Golden Conures or Golden Parakeets (Guarouba guarouba), and 0% (n=2) Hyacinth...

Autores: Carvalho,T.S.G.; Zangeronimo,M.G.; Saad,C.E.P.; Alvarenga,R.R.; Assis,V.D.L.; Pereira,V.M.; Scalon,J.D.; Silva,J.P.
Behavioural studies with cockatiels (Nymphicus hollandicus) in captivity are scarce. Due to the need for appropriate management of these animals, this study was performed to examine the behaviour of cockatiels kept in captivity at two temperatures. Sixteen cockatiels were individually housed in cages (62cm high x 43cm long x 27cm wide) and fed with a commercial ration and seed mixture for psittacids. Water was provided ad libitum. The eight-day experiment was divided into two stages of four days each. In the first stage, the birds were kept at room temperature (25°C) with 70% relative humidity during 24 hours. In the next stage, they were kept at 35°C from 06:00 to 18:00h and 25°C from 18:00 to 06:00h, also at 70% relative humidity. The behaviour of the...

Provedor de dados: 45
Autores: Souza,M.L.; Azuaga,L.B.S.; Coutinho Netto,C.R.M.; Gomes,D.C.; Ramos,C.A.N.; Leal,C.R.B.
ABSTRACT The maintenance of wild animals in captivity can be a source for transmission of infectious and zoonotic diseases. In February 2016, blue-fronted amazon parrots that were kept at the Centro de Reabilitação de Animais Silvestres (CRAS) of Campo Grande - MS died suddenly. The specimens were sent to the Universidade Federal de Mato Grosso do Sul (UFMS), Faculdade de Medicina Veterinária e Zootecnia (FAMEZ) to be necropsied. Anatomopathological exams were performed and organ fragments from all systems were collected for histopathological exams. Liver and spleen fragments were also collected for bacteriological exams. Histopathological exam revealed bacterial aggregates distributed through the organs. Bacteriological exam isolated Salmonella spp. from...

Isolation of Salmonella spp. in captive Psittaciformes from zoos and a commercial establishment of Fortaleza, Brazil
Provedor de dados: 45
Autores: Lopes,E.S.; Cardoso,W.M.; Albuquerque,Á.H.; Teixeira,R.S.C.; Salles,R.P.R.; Bezerra,W.G. A.; Rocha e Silva,R.C.; Lima,S.V.G.; Sales,R.J.P.F.; Vasconcelos,R.H.
This study showed a low prevalence of Salmonellaspp. in captive psittacines from zoos and a commercial establishment of Fortaleza. None of the isolated serotypes (S. Lexington, S. Saintpaul and S. Newport) have yet been reported in Amazona aestiva, Ara chloropteraor Melopsittacus undulatus. However, the fact that most birds presented negative for Salmonellaspp. may not imply the absence of this pathogen in these birds, since the intermittent excretion is a well-known characteristic of this microorganism.

ABSTRACT:  Cockatiels (Nymphicus hollandicus) are exotic birds thatoriginated from Australia.Because of their beauty and learning ability, they are one of the most popular pet birds among the Psittaciformes. The objective of this study was to report a case of leiomyosarcoma on the humeral musculature of the left wing of a cockatiel (Nymphicus hollandicus). The animal was admitted to the Wildlife Rehabilitation Center (NURFS-CETAS) of the Universidade Federal de Pelotas withswelling in the humeral region of the left wing. During surgery, the animal died and was transferred to the Laboratório Regional de Diagnóstico, Faculdade de Veterinária (LRD-UFPel). During histopathological evaluation (hematoxylin and eosin routine technique) of the tumor, spindle...
