ABSTRACT
Objective:To detect and characterizeChlamydophila psittaci(C. psittaci) in asymptomatic feral pigeons in centralThailand.Methods:A total814 swabs from the trachea and cloacae of407 non-clinical feral pigeons in centralThailand were collected and tested for the presence ofC. psittaci.Results:A10.8% of feral pigeons in the sample group were positive as determined by nestedPCR primer specific toC. psittaci.The outer membrane proteinA(ompA) gene of positive samples exhibited amino acid identity ofC. psittaci ranging from71 to100% and were grouped in genotypeB.Exceptionally,BF1676-56 isolate was closely related toChlamydia avium with 99% identification of the16S ribosomal(r)RNA gene.Conclusions:This is the first report onC. psittaci isolated from asymptomatic feral pigeons inThailand, which provides knowledge for the disease status in pigeon populations inThailand.
