Infections caused by the Chlamydiales order are highly prevalent worldwide and have a well-known association with reproductive and non-reproductive disorders in livestock and humans. This study aimed to identify Chlamydiales organisms in ruminant abortions using real-time polymerase chain reaction (qPCR) in samples collected from three Brazilian states: Rio Grande do Sul, Santa Catarina, and São Paulo. The Chlamydiales order was found in 7.

Ticks are vectors of numerous agents of medical importance and may be infected by various -related bacteria, such as members of and families, which are sharing the same biphasic life cycle with the pathogenic . However, the veterinary importance of ticks and of their internalized pathogens remains poorly studied. Thus, we wondered (i) whether the prevalence of ticks was higher in zoological gardens than in control areas with similar altitude, vegetation, humidity and temperature, and (ii) whether the presence of -related bacteria in ticks may vary according to the environment in which the ticks are collected.

This study aimed to investigate the presence of Chlamydia spp. and Parachlamydia acanthamoebae in bovine placental tissue originating from abortion and non-abortion cases in Belgium. Placentas of 164 late term bovine abortions (last trimester of gestation) and 41 non-abortion (collected after calving) cases were analysed by PCR for Chlamydia spp.

The family is a recent addition to the phylum. Its members were discovered in cockroaches and woodlice, but recent metagenomics surveys demonstrated the widespread distribution of this family in the environment. It was, moreover, estimated to be the largest family of the phylum based on the diversity of its 16S rRNA encoding gene.

Epitheliocystis is an emerging and global aquaculture disease caused by a diverse range of bacteria of the order Chlamydiales. Here we report a case of epitheliocystis caused by a novel Chlamydia bacterium, which resulted in 40% mortality in cultured cyprinids (Spinibarbus denticulatus). The affected fish exhibited lethargy, were observed swimming near the oxygen pump and subsequently died.
