“…Occasionally, also apparently healthy individuals can be severely affected [6,7]. In the last two decades, cases of zoonotic transmission were reported from psittacine birds [8], as well as ducks [9,10], turkeys [11] and mixed domestic poultry [7] as the main sources. In addition, humanto-human transmission was shown to be a relevant infection route in a number of cases [12][13][14][15][16].…”

Chlamydia (C.) psittaci, the causative agent of avian chlamydiosis and human psittacosis, is a genetically heterogeneous species. Its broad host range includes parrots and many other birds, but occasionally also humans (via zoonotic transmission), ruminants, horses, swine and rodents. To assess whether there are genetic markers associated with host tropism we comparatively analyzed whole-genome sequences of 61 C. psittaci strains. Initially, poorly assembled genomes in public databases were subjected to clean-up, reassembly and polishing. Multiple sequence alignment of the genome sequences revealed four major clades within this species. Clade 1 represents the most recent lineage comprising 40/61 strains and contains 9/10 of the psittacine strains, including type strain 6BC, and 10/13 of human isolates. Clades 2-4 carry strains from different non-psittacine hosts. We found that clade membership correlates with classification schemes based on SNP types, ompA genotypes, multilocus sequence types as well as plasticity zone (PZ) structure and host preference. Genome analysis also revealed that i) sequence variation in the major outer membrane porin OmpA can result in 3D structural changes of immunogenic domains, ii) past host change of Clade 3 and 4 strains could be associated with loss of MAC/perforin in the PZ, rather than the large cytotoxin, iii) the distinct phylogeny of atypical strains (Clades 3 and 4) is also reflected in their repertoire of inclusion proteins (Inc family) and polymorphic membrane proteins (Pmps). Altogether, our study identified a number of genomic features that can be correlated with the phylogeny and host preference of C. psittaci strains.

“…There have been reports of an epidemiological investigation based on an interdisciplinary, multi-team approach in Brazil following the confirmation of psittacosis cases, which resulted in the reorganization of shops selling bird pets and the referral of all infected parrots to veterinarians for treatment (Ferreira VL, Silva MV, Bassetti BR, Pellini ACG & Raso TF., 2017). Due to the potential public health risk of Chlamydia psittaci, the 2017 National Public Health Veterinary Association updated its Compendium of Tests and Strategies for the Management of Disease in Birds and Humans (Balsamo G, Maxted AM, Midla JW & et al, 2017).…”

Chlamydia psittaci infection can lead to severe clinical manifestations in humans, including rapidly progressive severe pneumonia, adult respiratory distress syndrome (ARDS), sepsis, multiple organ dysfunction, and even death. Here, we reported a 47-year-old man who presented with shortness of breath, fever and diarrhea. His chest CT showed right pneumonia with consolidation, and severe psittacosis pneumonia was confirmed by metagenomic sequencing of bronchoalveolar lavage fluid. The condition continued to worsen under ventilator treatment, and ARDS occurred. VV-ECMO was used to support for five days to improve hypoxia. In the middle and late stage of the disease course, the ALT of the patient showed an upward trend, and the HBV DNA and hepatitis B surface antigen were positive. Considering the medical history, it might be acute hepatitis B, and antiviral therapy was given. After three weeks of combined therapy, the patient recovered and was discharged from the hospital. Chlamydia psittacosis pneumonia is prone to misdiagnosis and misdiagnosis when the symptoms are not typical, and high-throughput sequencing is needed for definite diagnosis. Short-term use of ECMO in severe pneumonia of Chlamydia psittaci can help shorten the course of the disease and reverse the disease. The route of viral hepatitis B infection is unknown. If acute hepatitis B co-infection with other pathogens initiates antiviral therapy, it may prevent its transformation to chronic.

“…In addition to wearing protective clothing and a high-efficiency respirator (N95 rating), handlers of sick birds should also receive medical attention [18]. Effective preventative measures implemented in birds beforethe sale would improve the ability to stop the spread of disease to pet owners and other susceptible avian species [19].…”

The very high exotic or genetic value made pet birds, likecanaries, parakeets, and parrots a choice for trade across countries and continents, and the capability of these birds to act aspotential carriers or transmitters of zoonotic diseases contributes a significant threat to humans. Birds are characterized and known for their susceptibility, transmission, and maintenance of pathogens that are zoonotic to humans. Some of the zoonotic diseases they spread, such as highly pathogenic avian influenza (HPAI), salmonellosis, and chlamydophilosishave a significant impact on human health and these things make this issue a one health concern. Zoonotic diseases among birds areclassified as bacterial, viral, fungal, and of parasitic origin. The intensity with which they affect humans varies according to their pathogenicity and virulence. The awareness of pet bird zoonosesis of prime importance while trading or domesticating the bird, which will help to understand their potential fordiseases and install preventive measures accordingly. This review paper aims to educate readers about the risks faced by bird owners and the public by describing several instances of bird-human disease transmission and the characteristicsymptoms of those diseases.
