Abstract
Little information is available on the presence of chlamydia infection in wildlife. This study was conducted to assess the occurrence of chlamydiae in asymptomatic birds from two species of wild birds (Cattle Egret and Hoopoe) in Egypt. In the present study Chlamydiaceae was analyzed using Giemsa stain, Giménez stain, fluorescent antibody test (FAT) and PCR. The results of these techniques were compared with CFT for detecting Chlamydia psittaci antibodies among the examined birds. The results reveal that 96.4%, 81.8%, 89.1%, 80.0% and 58.2% of the examined samples were positive for chlamydiosis using PCR, Giemsa stain, Giménez stain, FA, and CFT respectively among Hoopoe. The percentages were 90.6%, 77.4%, 83.0%, 75.5% and 66.0% respectively for the previous tests among Cattle Egret birds. The results suggest that Cattle Egret and Hoopoe may be reservoir of Chlamydiaceae species and thus shed the organisms in their excreta. The shedding of chlamydiae by free living birds in Egypt may expose humans that come in contact with these birds to zoonotic risks.
