1. Isolation and Antimicrobial Resistance Profiles of Enterobacteria from Nestling Grey-Breasted Parakeets (Pyrrhura Griseipectus)
ABSTRACT The psittacine Pyrrhura griseipectus is a threatened species currently only found in Ceará State, Brazil. A microbiological survey was conducted to determine the composition of the enteric microbiota of this species, as well as the phenotypic profiles of antimicrobial susceptibility presented by the isolates. Cloacal swabs were collected from indiv

2. Survey of pathogens in threatened wild red-tailed Amazon parrot (Amazona brasiliensis) nestlings in Rasa Island, Brazil
ABSTRACT The red-tailed Amazon parrot (Amazona brasiliensis) is a threatened species of psittacine bird that inhabit coastal regions of Brazil. In view of the threat of this species, the aim of this study was to perform a health evaluation in wild nestlings in Rasa Island, determining the prevalence of enterobacteria and infectious agents according to type o

3. Captive wild birds as reservoirs of enteropathogenic E. coli (EPEC) and Shiga-toxin producing E. coli (STEC)
ABSTRACT Psittacine birds have been identified as reservoirs of diarrheagenic Escherichia coli, a subset of pathogens associated with mortality of children in tropical countries. The role of other orders of birds as source of infection is unclear. The aim of this study was to perform the molecular diagnosis of infection with diarrheagenic E. coli in 10 diffe

4. Molecular Diagnosis of Beak and Feather Disease in Native Brazilian Psittacines
ABSTRACT The incidence of the psittacine beak and feather disease virus (BFDV) was investigated in Brazilian native parrots with normal feathering arriving at rescue and triage centers for wild animals (CETAS, IBAMA) in the state of Minas Gerais, Brazil. BFDV DNA was investigated by previously described PCR technique for the partial amplification of BFDV ORF

6. Prebiótico na alimentação de filhotes de papagaio verdadeiro (Amazona aestiva) / Essay for prebiotic use in the feeding of nestlings of blue-fronted amazon in rehabilitation process.
O Brasil apresenta uma das maiores diversidades biológicas. Estima-se que 12 milhões de animais silvestres sejam contrabandeados anualmente. O papagaio verdadeiro (Amazona aestiva) é um dos psitacídeos mais populares do mundo. Existem poucos estudos sobre a nutrição desta ave, e os prebióticos podem ser uma alternativa para melhorar as condições san

7. Populações de psittacidae no Parque Estadual Mata dos Gody, fragmento de floresta atlântica no norte do Estado do Paraná, Brasil
Atlantic Forest in north of Paraná State Brazil has been almost completely depleted since the first half of XX century. Nowadays, only a few native forest remnants remains, most in private lands. The Godoy State Park is one of the biggest and most representative fragments that are left, and it is under governmental protection. This study aimed to asses popu

8. Determinação do sexo de psitacídeos por radioimunoensaio (RIE) de esteróides sexuais e por reação em cadeia pela polimerase (PCR) a partir de excretas cloacais / Psittacine sex determination by radioimunoassay (RIA) of sex steroids and by polimerase chain reaction (PCR) using fecal samples
Para o presente estudo, utilizaram-se amostras de excretas cloacais de 65 aves da família Psittacidae, previamente sexadas. Os andrógenos e estrógenos fecais foram extraídos com Tampão Fosfato Salino (PBS) e com uma solução PBS:Álcool Etílico (4:1) e a mensuração hormonal foi realizada em ?kits? comerciais para radioimunoensaio no Laboratório de

9. Comparison of avian Chlamydia psittaci isolates by restriction endonuclease analysis and serovar-specific monoclonal antibodies.
Avian Chlamydia psittaci isolates were examined by restriction endonuclease analysis and serovar-specific monoclonal antibodies and compared with ovine abortion and polyarthritis isolates. The avian isolates were divided into four serovars (turkey, psittacine, pigeon, and duck) based on their reactivity to the monoclonal antibodies. The DNA digest patterns w

10. Cloning and sequence analysis of the major outer membrane protein gene of Chlamydia psittaci 6BC.
The gene encoding the major outer membrane protein (MOMP) of the psittacine Chlamydia psittaci strain 6BC was cloned and sequenced. N-terminal protein sequencing of the mature MOMP indicated that it is posttranslationally processed at a site identical to the site previously identified in the MOMP of Chlamydia trachomatis L2. The nucleotide sequence of the C.

11. Serotyping of European isolates of Chlamydia psittaci from poultry and other birds.
A panel of five serovar-specific monoclonal antibodies which distinguish the five known avian serovars of Chlamydia psittaci was used to serotype 45 European avian Chlamydia psittaci isolates. Chlamydial antigen was grown in Buffalo green monkey (BGM) cells or in embryonated chicken eggs and was then inoculated into BGM cells. Serotyping was performed in an

12. Phylogenetic analyses of Chlamydia psittaci strains from birds based on 16S rRNA gene sequence.
The nucleotide sequences of 16S ribosomal DNA (rDNA) were determined for 39 strains of Chlamydia psittaci (34 from birds and 5 from mammals) and for 4 Chlamydia pecorum strains. The sequences were compared phylogenetically with the gene sequences of nine Chlamydia strains (covering four species of the genus) retrieved from nucleotide databases. In the neighb
