Dual sensory impairments in companion dogs: Prevalence and relationship to cognitive impairment.

PURPOSE: Many older dogs (Canis lupus familiaris) develop cognitive impairment. Dog owners often describe impairments in multiple sensory functions, yet the relationships between sensory and cognitive function in older dogs is not well understood. METHODS: We performed assessments of dog vision and hearing, both clinically (n = 91, electroretinography and brainstem auditory evoked potential) and via validated questionnaire (n = 238). We determined prevalence of sole and dual hearing/vision impairments in younger (<8 years) and older (≥8 years) dogs. Impairment cutoffs were determined using data from young dogs. We assessed the relationships between questionnaire-assessed vision and/or hearing impairments and cognitive impairment using logistic regression. RESULTS: Younger and older dog groups had similar distributions of sex and purebred/mixed breed status. Sex had no relationship to prevalence of sensory impairments. Older dogs had higher prevalence of hearing, vision, and dual sensory impairments, assessed both clinically and by questionnaire (P<0.001), and cognitive impairment assessed by questionnaire (P<0.001). Dogs had higher prevalence of reported cognitive impairment when owners reported dual vision and hearing impairments (79-94%, versus 25-27% in dogs with no sensory impairments), which was most consistent in dogs aged ≥8 years. In these older dogs, dual vision/hearing impairments were associated with a significantly increased risk of cognitive impairment (1.8-2.0 odds ratio). CONCLUSION: Dogs aged ≥8 years are at higher risk for dual hearing/vision impairments and associated cognitive impairments. The causal relationship between these impairments is not defined, but clinical consideration of these multimorbidity risks should be made in older dogs.

Pet owners feeding alternative diets.

A new BVA policy position on diets for cats and dogs has been published as figures show substantial numbers of vets have clients choosing to feed their animals alternative diets.

From small to tall: breed-varied household pet dogs can be trained to detect Parkinson's Disease.

Parkinson's Disease (PD) is a clinically diagnosed disease that carries a reported misdiagnosis rate of 10-20%. Recent scientific discoveries have provided evidence of volatile organic compounds in sebum that are unique to patients with PD. The primary objective of this study was to determine if companion dogs could be trained to distinguish between sebum samples provided by PD-positive patients and PD-negative human controls. This was a randomized, handler-blind, controlled study. Twenty-three canines of varying breeds, ages, and environmental backgrounds were included. The study period encompassed 200 total working days from 2021 to 2022. Factors investigated included donor gender and levodopa drug affectivity, as well as canine breed, age, and duration of training time. The findings in this study were compiled from data collected during the final two years of a seven-year research program. For this two-year reporting period, when averaged as a group, the 23 dogs were 89% sensitive and 87% specific to olfactory distinction between PD-positive and PD-negative human donor samples. Ten of the twenty-three dogs averaged 90% or higher in both sensitivity and specificity. In 161 separate trials, a dog was presented with both novel PD-positive and PD-negative samples. For these novel exposures, the dogs collectively averaged 86% sensitivity and 89% specificity. PD medication was also investigated and was found to have no discernible impact on canine sensitivity or specificity results. Study findings support the application of companion dogs, trained with force-free, reward-based methodologies, for the detection of PD-positive and PD-negative samples under controlled conditions.

Avian malaria in a feral-pet pigeon: a case report.

BACKGROUND: Avian malaria is caused by diverse parasite species of the genus Plasmodium, and it affects various bird species. The occurrence of this disease in some wild bird species is sparsely documented due to the scarce availability of samples. Hence the pathogenicity in some hosts is not completely known. In addition, feral birds may act as reservoirs bridging the transmission cycle from wild migratory birds to domestic and zoo-kept bird species. CASE PRESENTATION: An owner of pigeons adopted a feral pigeon (Columba livia forma domestica) and housed it together with his other pet-pigeons. The bird died unexpectedly a few weeks after a surgical procedure and necropsy revealed a severely anaemic carcass, with pale organs and hydropericardium. Histopathologic analysis revealed inflammatory infiltrates in the lung and liver, and monocytes and Kupffer cells contained haemozoin pigment indicative of phagocytosis of Plasmodium-infected erythrocytes. A high erythrocytic infection rate of 18% was evident in tissues and blood vessels in various organs. Furthermore, the thyroid had masses classified as thyroid carcinomas. Immunohistochemistry with anti- Plasmodium falciparum HSP70 antibody revealed positive signals in erythrocytes and intravascular leucocytes. Further microscopy analysis using a Hemacolor-stained impression smear revealed a high parasitaemia with an asynchronous infection showing all erythrocytic stages. Molecular diagnosis by PCR identified Plasmodium relictum, lineage GRW11 as the aetiological agent. The bird presented died most likely due to an acute infection as evidenced by the high blood parasitaemia, leading to major erythrocyte destruction. Further analyses of feral pigeons (n = 22) did not reveal any additional cases of Plasmodium infections. CONCLUSION: This study reports the first mortality associated with P. relictum lineage GRW11. The study supports previous studies, suggesting that Plasmodium infections are not frequent in pigeons. Host conditions like immunosuppression due to the tumour may have influenced the infection outcome in this fatal case. Use of anti-P. falciparum HSP70 antibody for detection of P. relictum antigens for immune assays in blood and tissue samples will be a useful tool for future studies.

Canine companionship as a resilience factor: a quantitative inquiry into the impact of pet ownership on burnout mitigation among radiologists and radiographers.

Background: The demanding nature of diagnostic imaging, coupled with the increasing workload and exposure to high-stress scenarios, underscores the pressing concern of burnout among radiologists and radiographers in modern healthcare settings. The objective was to investigate the interplay between family characteristics, workplace characteristics, pet ownership, and the occurrence of burnout. Methods: An online, quantitative, cross-sectional study with a non-random, purposive sampling method was carried out among Hungarian radiologists and radiographers from 1st of September to 1st of November 2022. Results: We examined the results of 406 responses predominantly from females (79.8%, n = 324), including 70.7% radiographers (n = 287). Cronbach's alpha values for depersonalization (DP), emotional exhaustion (EE), and personal accomplishment (PA) were 0.74, 0.88, and 0.85, respectively. Average burnout scores were 8.35 (SD = 6.62) for DP, 26.26 (SD = 12.74) for EE, and 32.86 (SD = 9.52) for PA. DP demonstrated a balanced distribution (low: 35.7%, moderate: 27.3%, high: 36.9%). Conversely, EE and PA skewed towards high levels, with 52.5% (n = 213) and 49.5% (n = 201). Significant associations were found between gender and DP (p = 0.006), age (31-40 years) and DP/PA (p < 0.001; p = 0.004), absence of children and all burnout dimensions (p < 0.05), and pet ownership (p = 0.004) with lower EE, particularly for dog owners (p = 0.009). Occupation lacked a significant effect on burnout dimensions (p > 0.05). Employees without a second job had higher EE (p = 0.002) and lower PA (p = 0.008). Increasing healthcare experience correlated with decreased DP values (p = 0.001), while working over 40 h weekly negatively impacted all burnout dimensions (p ≤ 0.05). 15.5% (n = 63) exhibited signs of high burnout, with the age group 31-40 demonstrating the highest proportion (25.4%, n = 27) and significant associations with marital status, absence of children, pet ownership, private healthcare, 10-19 years in healthcare, and working over 40 h weekly. Conclusions: There is a pressing need for evidence-based strategies to alleviate burnout among radiologists and radiographers. There is a growing importance of recognizing the role of pets, especially dogs, as valuable companions for emotional support and stress relief. Implementing pet-friendly policies or therapy programs can contribute to a positive and supportive workplace, potentially mitigating burnout among essential frontline healthcare professionals.

Culturally Responsive Care in Veterinary Medicine.

This article examines how culturally responsive care can enhance veterinary medicine by focusing on the interpersonal relationships between veterinarians, their teams, and pet owners. It begins by exploring the historical context of trust within veterinary practice and addresses stereotypes in pet ownership demographics, reinforcing the universal human-animal bond. The article outlines the components of culturally responsive care, noting the scarcity of research in veterinary settings and drawing extensively on the substantial research from human medicine, particularly nursing. It redefines veterinarians as trusted caregivers and details the benefits of culturally responsive care, advocating for more inclusive practices to inspire a more empathetic and culturally competent veterinary community.

Higher Frequency of SARS-CoV-2 RNA Shedding by Cats than Dogs in Households with Owners Recently Diagnosed with COVID-19.

Studies have demonstrated the susceptibility of companion animals to natural infection with SARS-CoV-2. Using quantitative reverse transcription polymerase chain reaction and sequencing analyses, this study investigated SARS-CoV-2 RNA excretion in pets in households with infected owners. Oropharyngeal and rectal swabs were collected from dogs and cats in Parana, Southern Brazil, between October 2020 and April 2021. Viral RNA was detected in 25% of cats and 0.98% of dog oropharyngeal swabs; however, systemic, respiratory, and gastrointestinal signs were absent. Complete viral genomes belonged to the Gamma lineage. Phylogenetic analyses indicated that pet samples were probably derived from human-positive cases in Parana. Viral excretion in the oropharynx was more frequent in cats than in dogs. Mutations in the S protein characteristic of Gamma strains were present in all sequenced SARS-CoV-2 strains. The receptor-binding domain of these Brazilian strains did not show any additional mutations not reported in the Gamma strains. Mutations in NSP6, NSP12, and N proteins previously mapped to strains that infect deer or minks were detected. This study highlights the importance of actively monitoring the SARS-CoV-2 strains that infect pets with continued viral exposure. Monitoring genetic changes is crucial because new variants adapted to animals may pose human health risks.

Mitigation and Preparedness of Pet Owners During Disasters.

There are numerous challenges for pet owners in developing countries before, during, and after disasters, comprising poor communication between pet owners and veterinarians for periodic pet check-ups, lack of necessary equipment, lack of proper disaster evacuation training, and a proper shelter to be considered for pets during periods of disasters. In the present letter, a variety of measures and recommendations have been provided, which can be kept in mind throughout the entire disaster management cycle to prevent pet loss.

Animal companionship and psycho-social well-being: Findings from a national study of community-dwelling aging Canadians.

A growing body of evidence has provided support for the beneficial impact of human-animal interactions on a range of biological, social, and psychological outcomes for humans; however, less is conclusively known about the association between animal companionship and psycho-social health specifically among aging populations. In this study, we assessed the association between animal companionship and psycho-social well-being in a large sample (N = 30,865) of community dwelling Canadians aged 45 and older. Using cross-sectional data from the Canadian Community Health Survey-Healthy Aging, we conducted hierarchical multiple regression to assess the relationship between animal companionship and four domains of psycho-social well-being (satisfaction with life, loneliness, depression, and levels of social support) after controlling for socio-demographic factors and psycho-social measures. Results indicate that those with animal companionship report significantly higher levels of social support than aging Canadians without animal companionship; however, animal companionship was also associated with significantly lower levels of life satisfaction and higher levels of both loneliness and depression. These findings complicate the existing literature on human-animal interactions by suggesting the benefits associated with animal companionship may vary across distinct domains of psycho-social health. As such, results from this study highlight the need for more nuanced model specifications when assessing the relationship between animal companionship and psycho-social well-being. Implications of these findings for the provision of social services to older adults with pets are provided.

Beginning with the End in Mind: Creating a Practice that Centers Equity-Part 1.

The concept of equity recognizes historical and current barriers and promotes thriving for veterinary teams and people and animals in the community. Veterinary medicine lacks sociodemographic diversity; veterinarians and other team members who identify with systemically excluded groups offer valuable contributions but are at risk of workplace discrimination. Client families who face barriers for financial and other reasons are at risk of poor animal health and welfare outcomes, including separation from their animals. This article is part one of 2 articles reviewing how the concept of equity applies and could transform well-being in companion animal veterinary practice in North America.

Beginning with the End in Mind: Creating a Practice that Centers Equity-Part 2.

The concept of equity recognizes historical and current barriers and promotes thriving for veterinary teams and people and animals in the community. It is possible to design equitable workplace systems to prevent and respond to harm using learnings from human medicine and the social sciences. These systems are grounded in the principles of health equity and must incorporate both formal policies and intentional cultivation of supportive culture and relationships. This article is part 2 of 2 articles reviewing how the concept of equity applies and could transform well-being in companion animal veterinary practice in North America.

When veterinarians treat plus-sized pets: Insights for veterinary practice.

Background: Obesity of companion animals in Canada is becoming a problem in veterinary practice. Cats and dogs, in particular, are increasingly overweight. However, prevention and treatment present challenges. Challenges in treating pet obesity, such as client nonadherence and animal welfare issues arising from obesity, also affect the well-being of veterinarians - especially given the coincident high rates of burnout and compassion fatigue experienced in the profession. Objective: This study investigated how practicing veterinarians perceive the treatment of overweight companion animals and how treating obese pets affects well-being of veterinarians. Animals and procedure: We recruited veterinarians who routinely treat companion animals in private practice to participate in focus group interviews. We also interviewed veterinarians who could not attend the focus group sessions, yet still wished to contribute. Through thematic data analysis, we generated key themes that illustrated how treating obese pets negatively affects veterinarian well-being. Results: Eighteen companion animal veterinarians contributed to this study. We generated 3 themes from the analysis that illustrate negative effects of treating obese pets on veterinarian well-being: i) negative feelings such as frustration and sadness associated with treating obese pets; ii) owners' lack of comprehension of the effects of obesity on pets, including early euthanasia; and iii) client nonadherence regarding treatment. Conclusion and clinical relevance: This study contributes to the veterinary literature on companion animal obesity by focusing on how treating pet obesity affects veterinarian well-being, especially given high rates of burnout and compassion fatigue in the profession. As pet obesity increases in society, obesity prevention and treatment is becoming central to companion animal veterinary practice. Our findings suggest that veterinarian well-being is negatively affected in connection with companion animal obesity. We recommend relationship-centered communication, increased nutritional expertise, and a focus on wellness in the workplace to improve veterinarian well-being while treating pet obesity.

Quand les vétérinaires traitent des animaux en surpoids : perspectives pour la pratique vétérinaire. Contexte: L'obésité des animaux de compagnie au Canada devient un problème dans la pratique vétérinaire. Les chats et les chiens, en particulier, sont de plus en plus en surpoids. Cependant, la prévention et le traitement présentent des défis. Les défis liés au traitement de l'obésité des animaux de compagnie, tels que la non-observance des traitements par les clients et les problèmes de bien-être animal liés à l'obésité, affectent également le bien-être des vétérinaires ­ en particulier compte tenu des taux élevés d'épuisement professionnel et de fatigue de compassion que connaît la profession. Objectif: Cette étude a examiné comment les vétérinaires en exercice perçoivent le traitement des animaux de compagnie en surpoids et comment le traitement des animaux obèses affecte le bien-être des vétérinaires. Animaux et procédure: Nous avons recruté des vétérinaires qui traitent régulièrement des animaux de compagnie en cabinet privé pour participer à des entretiens de groupe. Nous avons également interrogé des vétérinaires qui n'avaient pas pu assister aux séances de groupe de discussion, mais qui souhaitaient néanmoins contribuer. Grâce à l'analyse thématique des données, nous avons généré des thèmes clés illustrant comment le traitement des animaux obèses affecte négativement le bien-être des vétérinaires. Résultats: Dix-huit vétérinaires d'animaux de compagnie ont contribué à cette étude. Nous avons généré 3 thèmes à partir de l'analyse qui illustrent les effets négatifs du traitement des animaux obèses sur le bien-être du vétérinaire : i) les sentiments négatifs tels que la frustration et la tristesse associés au traitement des animaux obèses; ii) le manque de compréhension des propriétaires des effets de l'obésité sur les animaux de compagnie, y compris l'euthanasie précoce; et iii) la non-observance du traitement par les clients. Conclusion et pertinence clinique: Cette étude contribue à la littérature vétérinaire sur l'obésité des animaux de compagnie en se concentrant sur la façon dont le traitement de l'obésité des animaux de compagnie affecte le bien-être des vétérinaires, en particulier compte tenu des taux élevés d'épuisement professionnel et de fatigue de compassion dans la profession. À mesure que l'obésité des animaux de compagnie augmente dans la société, la prévention et le traitement de l'obésité deviennent essentiels à la pratique vétérinaire des animaux de compagnie. Nos résultats suggèrent que le bien-être des vétérinaires est affecté négativement par l'obésité des animaux de compagnie. Nous recommandons une communication centrée sur les relations, une expertise nutritionnelle accrue et une concentration sur le bien-être au travail pour améliorer le bien-être des vétérinaires tout en traitant l'obésité des animaux de compagnie.(Traduit par Dr Serge Messier).

Making fetch happen: Prevalence and characteristics of fetching behavior in owned domestic cats (Felis catus) and dogs (Canis familiaris).

Both cats and dogs fetch, but the likely function(s) of this behavior for each species have not been compared. In this study, we assessed data from online surveys of cat and dog behavior (Fe-BARQ; C-BARQ) completed by cat (N = 8224) and dog owners (N = 73724). We assessed responses to the items "Plays 'fetch'; likes to retrieve thrown objects or toys" (Fe-BARQ) and "Will 'fetch' or attempt to fetch sticks, balls, or objects" (C-BARQ). Cats and dogs described as "sometimes," "usually" or "always" fetching were categorized as fetchers. Regression models were used to examine which animal-related (e.g., sex, age) and environmental factors best predicted fetching, and chi-square tests were used to explore the effect of breed on fetching behavior. Fetching was reported in 40.9% of cats and 77.8% of dogs. In cats, fetching was correlated with play and activity. In dogs, fetching was correlated with overall trainability. In both cats and dogs, being female, older, living with (other) dogs, and having health problems decreased the likelihood of fetching. Breed effects were observed in both species, with fetching more prominent in cat breeds originating in the Far East (e.g., Burmese, Siamese, and Tonkinese) and in dog breeds from the Retriever, UK Rural, Poodle, Pointer and Spaniel clades. We discuss the results in the context of domestication history of both cats and dogs and posit several hypotheses about why fetching behavior is observed in both.

Assessing perceptions of flea and tick infestation risk in Southeast Queensland, Australia.

Social cognitive models are useful for improving our understanding of the relationship between people's health beliefs and disease risks and have been widely employed in human medicine. In veterinary science, there is little research about owners' perceptions of pet health and parasitic infections/infestations, despite the risk of transmission of zoonotic pathogens by ectoparasites. This study investigated the effects of demographic factors on pet owner's perception of ectoparasite infestation risk and behaviours related to animal health in southeast Queensland, Australia employing the Health Belief Model (HBM). A total of 241 dog owners were surveyed in 2018. The electronic survey was generated through SurveyMonkey and distributed utilising UQ SVS and Royal Society for the Prevention of Cruelty to Animals (RSPCA) email networks, informative posters and brochures placed in selected veterinary clinics, and in-person visits to dog parks. The relationship between dog owners' perception of flea and tick infestation risk was assessed using an adaptation of the Health Belief Model, social cognitive framework for health protection. Most survey respondents were between 26 and 45 years of age (40%), identified themselves as females (83%) and had a bachelor's degree (43%). Our results indicate that female owners had greater level of health concern related to ectoparasites compared to males. Similarly, owners aged 18 to 25, with a grade 10 to 12 level of attained education and living predominately in a rural setting showed greater level of health concern related to ectoparasite infestations. The results also indicated that cat owners had on average, higher levels of health concern than dog owners. Our study indicates that the perceptions of pet owners towards perception of flea and tick infestation risk varies demographically, and owner education is an important predictor of prevention behaviours towards tick and flea infestation of pets.

Influences of Animal-Assisted Intervention With Canine and Feline Pen Pals on Experiences of Living With Cancer and Blood Disorders in Children and Adolescents.

Background: Animal-assisted intervention (AAI) involving live visits with canines shows strong promise to improve quality of life (QOL) in hospitalized youth with cancer or blood disorders. The emerging field of virtual AAI allows access to AAI regardless of setting and extends to children at home. Youth and Pet Survivors™ (YAPS) is a novel form of virtual AAI with dog and cat pen pals who share a diagnosis of cancer or serious illness. Little is known about how exchanging letters with animals with a shared diagnosis influences perceived QOL, and how the human-animal bond (HAB) is expressed in letter narratives. Method: A thematic narrative analysis approach was used to analyze a secondary dataset consisting of letters and interviews from children in YAPS. The research team designed a conceptual framework to guide the analysis, integrating concepts of perceived QOL, the HAB, and emotional social support. Results: Collectively, the letter and interview texts illustrated cocreated stories of the HAB. Themes included the virtual HAB as a mirror, constructing identity in the context of the HAB, expressions of the mutuality of the HAB, happiness with having a pen pal, illness story, and connection to normalcy. Answers to research questions operationalize the influence of virtual AAI. Discussion: Having an animal pen pal improved perceived QOL and was a potent source of emotional social support across the illness trajectory, supporting YAPS as a nurse-led intervention for facilitating adjustment to illness. This study adds a conceptual framework and scientific evidence to the emerging field of virtual AAI.

Companion animals and child development outcomes: longitudinal and cross-sectional analysis of a UK birth cohort study.

BACKGROUND: Research into the impact of social relationships on childhood and adolescent health and wellbeing has been largely limited to children's relationships with other humans, while studies into the impact of pet ownership are sparse and have generally not adjusted for potential confounders. This study aimed to investigate the association between pet ownership and a range of developmental outcomes in childhood and adolescence. METHODS: Data were self-reports and direct assessments of approx. 14,000 children from the Avon Longitudinal Study of Parents and Children (ALSPAC). Multivariable regression models adjusting for confounding factors examined associations between developmental outcome measures (emotional health, behavioural development, cognitive development, language development, educational attainment) and concurrent pet ownership, including species, and also longitudinal pet ownership history and pet-interaction where possible. Analyses model numbers using multiple imputation varied from n = 393-8963. RESULTS: In cross-sectional analyses, owning a dog (b = 0.24, [0.06-0.41], p = .004) and owning other/miscellaneous pets (b = 0.18, [0.03-0.33], p = .021) at age 3 were associated with higher prosocial behaviour score. Owning a pet was associated with a higher non-verbal communication score at age 2 (cross-sectional, b = 0.18, [0.04-0.32], p = .014), and a higher language development score at age 5 (cross-sectional, b = 1.01, [0.18-1.83], p = .017). However, pet ownership was associated with lower educational attainment across a number of academic subjects and timepoints, in both cross-sectional and longitudinal analyses. It was also cross-sectionally linked to hyperactivity at age 3 and conduct problems at age 3 and 11. Furthermore, at age 8, cross-sectional analysis showed that children who owned any pets (OR [95% CI]: 0.85 [0.73-0.98], p= ·026) or cats (0.83, [0.73-0.95], p= ·006) had lower odds of high self-esteem (scholastic competence). CONCLUSIONS: Using a large, well-designed longitudinal study and adjusting for key confounders, we found little evidence of cross-sectional or longitudinal associations between pet ownership and emotional health or cognitive outcomes in children. There may, however, be some cross-sectional and longitudinal association with poorer educational attainment and a positive impact on social interactions as seen through associations with enhanced language development and prosocial behaviour. This study demonstrates the importance of adjustment for confounding variables and suggests that, contrary to popular belief, positive impacts of pet ownership on childhood development may be mainly limited to social behaviour and language development.

Effective treatment with afoxolaner (NexGard) of Trixacarus caviae in a pet guinea pig.

Trixacarus caviae is a sarcoptic mange mite infesting guinea pigs. Infestation in immunosuppressed animals produces severe dermatological problems, including alopecia, intense pruritus, hyperkeratosis and non-dermatological issues (e.g., seizures). Treatment options are limited and include topical application of macrocyclic lactones or amitraz or injectable administration of ivermectin or doramectin. Considering the severity of the disease and the challenging treatment, the present paper aimed to determine the efficacy of oral afoxolaner in a severe case of infestation with T. caviae in a pet guinea pig. One female guinea pig was referred to the New Companion Animal Clinic due to severe dermatological problems. A clinical evaluation was done, and skin scrapings were collected and examined under the microscope. Small mites were detected and morphologically identified as T. caviae. The animal was treated with a single oral dose of 2.50 mg/kg afoxolaner, and the lesions, presence/absence of mites and intensity of pruritus were evaluated periodically until 2 months post-treatment. A week after the medication, the lesions were milder, but pruritus was still present and was attributed to the healing process. Further examinations showed significant improvement with the complete remission of clinical signs and no mites at the microscopic examination after 4 weeks. Afoxolaner was safe and effective in this guinea pig for the treatment of T. caviae mange with no repetition needed.

Prevalence and genotypes of Chlamydia psittaci in pet birds of Hong Kong.

Psittacosis, or parrot fever, is a zoonotic disease caused by Chlamydia species associated with birds. One of the causative agents of the disease is Chlamydia psittaci, which is commonly carried by psittacine and other bird species, can be highly pathogenic and virulent to humans. In Hong Kong, a city with high population density, psittacosis is a notifiable disease with over 60% of cases in the last decade resulting in hospitalization. However, the sources of transmission of C. psittaci and its prevalence in pet birds in Hong Kong are currently unknown. To evaluate the risks of psittacosis transmission through pet birds, we tested the presence of C. psittaci and determined its genotypes in samples obtained from 516 captive birds from households, pet shops, and a veterinary hospital in Hong Kong. Results revealed that five samples (0.97%), collected from budgerigars and cockatiels, were C. psittaci-positive, while four (80%) of them were obtained from pet shops. Our phylogenetic analysis revealed that all identified strains belonged to Genotype A and showed high similarity to other sequences of this genotype obtained from various geographical locations and host species, including mammals. Our findings provide evidence for the presence of Chlamydia psittaci and shed light on its sources in captive birds in Hong Kong. They highlight the potential zoonotic risks associated with this pathogen, which can affect both humans and wild birds.
