“…By examination of Gimenez stained yolk sac membrane impression smear of infected chicken embryo by wild birds isolate, the percentage of infection was 76, 83.3, 82 and 95% in tree sparrows, doves, native quails and migratory quails, respectively. These results are in the same line with a previous study in Egypt conducted by El-Jakee [27], who analyzed Chlamydophila by using Gimenez stain for hoopoe and cattle egret and the positive ratios were 89.1 and 83%, respectively.…”

“…Similarly, high rates of Chlamydophila species (67.3%) from migratory birds was recorded previously in Egypt [26]. Moreover, EL -Jakee [27] recorded 81.8 and 77.4% prevalence rates for Chlamydophila species from cattle egret and hoopoe, respectively. In case of pet birds (budgerigars, love birds, finches, and cockatiels), high rates of Chlamydophila species were also recorded (85, 80, 100and 80%, respectively These results agree with a previous result recorded in Egypt [28].…”

Chlamydophila psittaci is one of the most important, zoonotic pathogen of birds causing chlamydiosis. This study aimed to investigate the frequency of infection by Cp. psittaci and to determine the genotype in birds at potential risk of exposure to this pathogen. In total four species of wild birds (50 native and 40 migratory quails, 30 doves and 25 tree sparrows) and four species of pet birds, (20 Budgerigars,10 cockatiels, 3 finches, 5 love birds) were examined for the presense of Chlamydophila psittaci using impression smears stained with Giemsa stain, smears from yolk sacs were stained with Gimenez stain and PCR . The results were (80%-100%) , (85%-100%) and (80%-100%) in pet birds followed by wild birds (64%-85%) , (76%-95%) and (80%-90%), respectivelly The pathogencity of three isolates by intratracheal route with 10 6 TCID/ml in 15 days old chickens and quails was done and showed that the more pathogenic strain for chickens and quails was the pet birds strain. The observed clinical signs were respiratory signs, conjunctivitis, and diarrhea, While the pathological changes were congestion in liver, lung, spleen, and pericarditis while mild clinical and pathological changes were observed post infection by tree sparrows and migratory quails isolates. The partial ompA gene sequence of isolated Cp. psittaci strain was placed in genotype A of Cp. psittaci which had the highest identity (91.9-94%) with previously similar described strains of genotype A. Pet and wild birds were the major reservoir for Cp. psittaci which shed in their excreta and expose human and native birds to high zoonotic risk.

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 (52Á5%) 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 (47Á5%). 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.

“…Surveillance of pelicans ( Pelecanus onocrotalus ) in South Africa found no positive individuals [ 87 ]. There is limited evidence to suggest that Chlamydia are present in wild birds in Egypt [ 111 ]. However, we were unable to find any other studies of chlamydial infection in wild African birds.…”

A Review of Chlamydial Infections in Wild Birds

The Chlamydia are a globally distributed genus of bacteria that can infect and cause disease in a range of hosts. Birds are the primary host for multiple chlamydial species. The most well-known of these is Chlamydia psittaci, a zoonotic bacterium that has been identified in a range of wild and domesticated birds. Wild birds are often proposed as a reservoir of Chlamydia psittaci and potentially other chlamydial species. The aim of this review is to present the current knowledge of chlamydial infections in wild avian populations. We focus on C. psittaci but also consider other Chlamydiaceae and Chlamydia-related bacteria that have been identified in wild birds. We summarise the diversity, host range, and clinical signs of infection in wild birds and consider the potential implications of these infections for zoonotic transmission and avian conservation. Chlamydial bacteria have been found in more than 70 species of wild birds, with the greatest chlamydial diversity identified in Europe. The Corvidae and Accipitridae families are emerging as significant chlamydial hosts, in addition to established wild hosts such as the Columbidae. Clarifying the effects of these bacteria on avian host fitness and the zoonotic potential of emerging Chlamydiales will help us to understand the implications of these infections for avian and human health.
