The Chlamydiae are a phylum of obligate intracellular, Gram-negative bacteria with a biphasic lifecycle. Commonly found in the environment, they infect a variety of hosts, including amoebae, insects, aquatic animals, reptiles, birds, and mammals (including humans), with Chlamydiaceae representing the most important pathogenic family in the phylum [1,2]. Apart from the strict human pathogen Chlamydia (C.) trachomatis, the successful and enigmatic animal-associated species remain in the spotlight as significant pathogens of wildlife; domesticated animals; pets; and potentially, humans. C. suis, C. abortus, C. pecorum, and C. psittaci infect a wide range of livestock hosts (pigs, sheep, cattle, horses, and poultry) and may cause diseases resulting in economic losses [1]. However, these same species also readily infect wildlife hosts. The best examples are C. pecorum, a species globally known as the ‘koala chlamydia’, causing severe ocular and urogenital infections in koalas, and C. psittaci, a species infecting a wide range of birds as well as unusual hosts, such as wallabies, rabbits, and guinea pigs. Other species such as C. felis and C. caviae are typically restricted to domestic pet hosts, cats, and guinea pigs; however they also pose a risk to humans, specifically pet owners [1]. Despite considerable progress in recent years concerning the diagnostic identification as well as our molecular and cell biological understanding of these different species, many questions remain regarding their genetic diversity, epidemiology, and pathogenesis. Accordingly, we assembled a collection of original research articles, brief reports, and a review from researchers across Asia, Australia, Europe, and North America to advance our knowledge of these veterinary Chlamydiaceae species and to clarify their role as pathogens in both veterinary and human medicine.
