Plain-English summary
Researchers in Buenos Aires, Argentina, studied 90 pet birds, specifically looking for the presence of bacteria called Chlamydia, which can cause illness. They found that about 30% of the birds tested positive for these bacteria, with the majority being Chlamydia psittaci, which is known to cause respiratory issues and other symptoms in birds. Most of the infected birds were younger than one year and showed signs of illness related to chlamydiosis, a disease caused by these bacteria. This study helps us better understand the types of Chlamydia affecting birds in the area.
Abstract
In order to determine the presence and genetic diversity of Chlamydia spp. in the north-eastern area of Buenos Aires province, Argentina, conjunctival, oropharyngeal, cloacal swab and tissues were collected from a total of 90 psittacine pet birds of different age and clinical manifestations. Through molecular methods, Chlamydiaceae was detected in 30% (27/90) of the samples, out of which 70.3% (19/27) were positive for Chlamydia psittaci and 14.9% (4/27) for Chlamydia abortus. Nine C. psittaci positive samples were genotyped by ompA gene sequences, 8 clustered within genotype A and 1 within genotype B. A significant association was observed between the presence of Chlamydia spp. and the manifestation of clinical signs compatible with chlamydiosis, as well as with the age of the birds (younger than one year old). This report contributes to the improvement of our understanding of chlamydial agents in our country.
