Four years ago a Guest Editorial in The Veterinary Journal posed the question ‘What is the prevalence and economic impact of chlamydial infections in cattle?’ (Livingstone and Longbottom, 2006). Although Chlamydophila abortus and C. pecorum are still considered the most important potential pathogens in cattle, with possible roles for C. psittaci and the related bacterium Waddlia chondrophila (Henning et al., 2002), more recent evidence suggests infection with Chlamydia suis (Teankum et al., 2007 K. Teankum, A. Pospischil, F. Janett, E. Brugnera, L.E. Hoelzle, K. Hoelzle, R. Weilenmann, D.R. Zimmermann, A. Gerber, A. Polkinghorne and N. Borel, Prevalence of chlamydiae in semen and genital tracts of bulls, rams and bucks. Theriogenology, 67 (2007), pp. 303–310. Teankum et al., 2007) and a related member of the order Chlamydiales, Parachlamydia acanthamoebae, may also contribute (Ruhl et al., 2009).
