Abstract The oral microbiome is a community of microorganisms, comprised of bacteria, fungi, viruses, archaea, and protozoa, that form a complex ecosystem within the oral cavity. Although minor perturbations in the environment are frequent and compensable, major shifts in the oral microbiome can promote an unbalanced state, known as dysbiosis ...

Abstract Intracellular growth and pathogenesis of Chlamydia species is controlled by the availability of tryptophan, yet the complete biosynthetic pathway for l‐Trp is absent among members of the genus. Some representatives, however, preserve genes encoding tryptophan synthase, TrpAB – a bifunctional enzyme catalyzing the last two steps in l‐Trp ...

DNAs of Theileria sergenti/orientalis/buffelli and Ehrlichia canis were detected for the first time in ruminant abortion products. The 51% of analyzed samples resulted positive for at least one of the pathogens searched and the 40% of samples resulted co‐infected. Positive and statistically significant index of co‐infection (Ic) were detected in double

Method for cryopreservation of Paramoeba perurans
Abstract Paramoeba perurans causes amoebic gill disease (AGD), which is a major problem in aquaculture worldwide. The parasite can be cultured in vitro, but to this date, no method for long‐term storage of the clones exists. In this study, we describe a method for cryopreservation of Paramoeba perurans.

Chlamydialesand the innate immune response: friend or foe? [PDF]
Pathogenicity of Chlamydia and Chlamydia-related bacteria could be partially mediated by an enhanced activation of the innate immune response. The study of this host pathogen interaction has proved challenging due to the restricted in vitro growth of these strict intracellular bacteria and the lack of genetic tools to manipulate their genomes.

Emerging evidence points to the gut microbiota as an important factor influencing host health. In wild birds, the authors show that a less diverse microbiota early in development is associated with larger‐than expected weight at a later development stage.

Chlamydiales – Taxonomy, Pathogenicity, and Zoonotic Potential [PDF]
Abstract Changes in the taxonomy of the order Chlamydiales, after its separation from the order Rickettsiales, were presented. These changes resulted in the recognition of the following families: Chlamydiaceae, Chlavichlamydiaceae, Criblamydiaceae, Parachlamydiaceae, Piscichlamydiaceae, Rhabdochlamydiaceae, Simkaniaceae, and Waddliaceae.

Novel Chlamydiales associated with epitheliocystis in a leopard shark Triakis semifasciata [PDF]
The Chlamydiales is a diverse order of obligate intracellular gram-negative bacteria that are known to cause a wide range of diseases in terrestrial animals, including humans. Molecular analyses have revealed that these organisms are also associated with epitheliocystis in teleost fish species, highlighting the suspected deep evolutionary origin of ...

Toward an understanding of the function of Chlamydiales in plastid endosymbiosis
Plastid endosymbiosis defines a process through which a fully evolved cyanobacterial ancestor has transmitted to a eukaryotic phagotroph the hundreds of genes required to perform oxygenic photosynthesis, together with the membrane structures, and cellular compartment associated with this process.
