Introduction:
Knowledge of the obligate intracellular bacteria from the Chlamydiaceae family has increased significantly in recent years. Not only new chlamydia species, such as Chlamydia avium or C. buteonis in birds have been described, but also known chlamydia in new host species, such as C. psittaci in horses. This review article provides an up-to-date overview of the zoonotic potential of C. psittaci, C. abortus, C. caviae and C. felis and summarizes current findings on other chlamydia species in different animal species; supplemented by information on optimal sampling and pathogen detection.
Insights
Recent discoveries reveal new Chlamydia species and hosts, increasing awareness of zoonotic potential. This review covers key species, animal hosts, and detection methods for Chlamydia infections.
Area of Science:
- Veterinary Microbiology
- Zoonotic Diseases
- Bacterial Pathogenesis
Context:
- Significant advancements in understanding Chlamydiaceae family bacteria.
- Identification of novel chlamydia species (e.g., Chlamydia avium, C. buteonis) in avian hosts.
- Detection of known chlamydia species in new host animals, such as Chlamydia psittaci in horses.
Purpose:
- To provide an updated overview of the zoonotic potential of Chlamydia psittaci, Chlamydia abortus, Chlamydia caviae, and Chlamydia felis.
- To summarize current research on various chlamydia species across different animal populations.
- To offer guidance on optimal sampling techniques and pathogen detection strategies for chlamydial infections.
Summary:
- This review details emerging chlamydia species and their hosts, emphasizing the growing knowledge of the Chlamydiaceae family.
- It critically examines the zoonotic implications of common chlamydia pathogens and their presence in diverse animal reservoirs.
- The article also includes practical information on effective sample collection and diagnostic methods for chlamydia detection.
Impact:
- Enhances understanding of chlamydia transmission dynamics between animals and humans.
- Informs veterinary diagnostics and public health surveillance for zoonotic chlamydia.
- Supports the development of targeted control and prevention strategies for chlamydial diseases in animal populations.
