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.

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.

Occurrence of Chlamydiaceae in Raptors and Crows in Switzerland.
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.

Chlamydophila psittaci genotype E/B transmission from African grey parrots to humans.
TL;DR: Thirty-six birds from a parrot relief and breeding centre, as well as the manager, were examined for the presence of Chlamydophila psittaci, and the currently described genotype E/B strain apparently caused no severe clinical symptoms in either parrots or humans.

Comparison of Pharyngeal, Fecal, and Cloacal Samples for the Isolation of Chlamydia Psittaci from Experimentally Infected Cockatiels and Turkeys
TL;DR: The pharyngeal swabs were the most reliable sample for isolation of chlamydia from live birds, however, no single sampling site yielded positive results from all infected birds.

TL;DR: This is the first study to document how the interconnectedness between feral pigeon subpopulations favours the spread of C. psittaci, the agent of psittacosis in humans, in the urban environment.

TL;DR: Both new genotypes, particularly genotype J, are intermediate between the two species, C. psittaci and C. abortus, and are suggested to be provisional genotypes I and J, respectively.

TL;DR: Prevalence and geometric mean titers of IgG antibodies to C. pneumoniae in patients with pneumonia and bronchitis was not statistically higher than in the normal adult population, and evidence of cross-reactivities in the MIF test between different species was found in both prevalence and GMT.
