RESUMEN La determinación de Chlamydia psittaci (Cp) en aves psitácidas en parques zoológicos de Venezuela representa una estrategia de conservación y preservación para este grupo de aves, donde múltiples especies se encuentran amenazadas de extinción y otras han perdido su capacidad de reincorporación a su hábitat natural. A través de la reacción en cadena de la polimerasa anidada (PCR) fue amplificada la subunidad 16S del ADNr de Cp en 50 muestras de hisopado cloacal de aves psitácidas, reportando una frecuencia de 62 %. El trabajo fue realizado en el Parque Zoológico Las Delicias (PZD) 8 % y el Aquarium de Valencia (AV) 54 %. La elevada frecuencia fue asociada a un genotipo de baja concentración y virulencia debido a la ausencia de signos clínicos de...

Screening of Feral Pigeons (Columba livia) for Pathogens of Veterinary and Medical Importance Rev. Bras. Ciênc. Avic.
Ferreira,VL; Dias,RA; Raso,TF.
ABSTRACT Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/Gallinarum. Positive samples were submitted to hemagglutination inhibition (HI) and tube seroagglutination tests, respectively. Molecular techniques (RT-PCR and PCR) were performed for Newcastle Diseases Virus (NDV) and Chlamydia psittaci diagnosis. Additionally, HI test was applied to detect antibodies against NDV. Serological results by RST were 3.3% positive for M. synoviae, 2.5% for M. gallisepticum, and 0.4% for S....

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 of nest. Blood samples were collected from 64 birds and evaluated for antibodies of Chlamydia psittaci by commercial dot-blot ELISA. Cloacal and oropharyngeal swabs samples were collected from 23 birds from artificial wooden nests, 15 birds from PVC nests and 2 birds from natural nests for microbiological analysis. Swab samples were collected from 58 parrots for C. psittaci detection by PCR and from 50...
