Aims The aim of this study was to determine the prevalence and potential risk factors associated with Chlamydia psittaci infections in psittacine birds and bird handlers in Egypt. Methods and results A total of 190 swabs were collected from psittacine birds (n = 120) and bird handlers (n = 70) and were tested by polymerase chain reaction to detect the C. psittaci ompA gene. Chlamydia psittaci DNA was detected in 63 (52·5%) of 120 samples collected from psittacine birds. The occurrence of C. psittaci infections was high in Cockatiel birds (60%), followed by Fischer's lovebird (51%) and Rosy-faced lovebird (47·5%). Bird age, location (pet markets and households), housing (caged and aviary), and sampling season were considered significant risk factors for C. psittaci infections in psittacine birds. Of the 70 sputum swabs collected from bird handlers, only 4 (6%) were positive for C. psittaci. Positive cases were closely associated with older persons (≥30 years) who had respiratory signs and handled birds in pet markets. Further, wearing protective gloves and washing hands when handling psittacine birds decreased the frequency of C. psittaci infections in bird handlers. Conclusions The prevalence of C. psittaci infections in psittacine birds in Egypt is high, which has a potential threat to human health in this area. Thus, dissemination of effective prevention and control measures is essential to prevent the spread of C. psittaci among psittacine birds, as well as among humans in contact with birds. Significance and impact of the study Results from this study highlighted the risk factors associated with C. psittaci infections in psittacine birds and bird handlers in Egypt and will aid in developing prevention and control measures to reduce the risk of C. psittaci infection.read more

Species, sex and geographic variation in chlamydial prevalence in abundant wild Australian parrots.
Helena S. Stokes,Johanne M. Martens,Ken Walder,Yonatan Segal,Mathew L. Berg,Andrew T. D. Bennett +5 more
TL;DR: A higher chlamydial prevalence than previously reported in many wild parrots is revealed, with implications for potential reservoirs, and transmission risks to humans and other avian hosts.

TL;DR: The common bacterial, viral, and parasitic infections in pigeons are summarized to provide insights for veterinarians and researchers studying pigeons to develop effective and efficient immunoprophylactic and diagnostic tools for pigeon diagnosis and therapeutics.

TL;DR: The findings suggest that wild parrots are a reservoir of both known and novel Chlamydiales lineages, of zoonotic and pathogenic potential, and indicate that host-specific and temporal factors are associated with infection risk.

TL;DR: The infection rate of Chlamydiaceae in corvids was high compared to rates reported in other wild bird species, and it can be suggested that raptors and crows pose a potential hazard to the health of their handlers.

TL;DR: Pet birds could act as potential reservoirs for zoonotic bacterial pathogens; thus, posing a risk to their human contacts, according to this study.

Seroprevalence and risk factors of Chlamydia psittaci infection in domestic geese Anser domestica, in Hainan province of China.
TL;DR: The results of the present investigation indicated the high seroprevalence of C. psittaci infection in geese in Hainan province, tropical China, and public education should be implemented to reduce the risk of avian to human transmission of such a pathogenic agent.

Chlamydia species in free-living Cattle Egret (Bubulcus ibis) and Hoopoe (Upupa epops) in Egypt
Jakeen K. El-Jakee,Kamelia M. Osman,Nashwa A. Ezzeldeen,Nashwa A. Ezzeldeen,H. A. Ali,Eman R. Mostafa +5 more
TL;DR: The results suggest that Cattle Egret and Hoopoe may be reservoir of Chlamydiaceae species and thus shed the organisms in their excreta and the shedding of chlamydiae by free living birds in Egypt may expose humans that come in contact with these birds to zoonotic risks.
