Respiratory tract bacteria distribution and transmission patterns among individuals in close contact.

Background: Respiratory disease outbreaks frequently occur in settings where individuals are in close contact, for example, schools and factories. However, the transmission patterns of oropharyngeal microbiota among healthy individuals living in clusters are unclear. Therefore, we aimed to investigate the respiratory tract bacteria distribution and transmission patterns among individuals in close contact.

Flaviflexus equikiangi sp. nov. isolated from faeces of Equus kiang (Tibetan wild ass) and carrying a class 1 integron gene cassette in its genome.

Two Gram-stain-positive, catalase-negative, non-spore-forming, cocci-shaped strains (dk850 and JY899) were isolated from the feces of Equus kiang in the Qinghai-Tibet Plateau of China. 16S rRNA gene sequence-based phylogenetic analyses showed that strains dk850 and JY899 belong to the genus Flaviflexus, closest to F. salsibiostraticola KCTC 33148, F.

sp. nov. and sp. nov., two new rapidly growing mycobacterial species.

Four bacterial strains (LJ126/S18 and Z-34/S20) recovered from faecal samples of Tibetan antelopes on the Qinghai-Tibet Plateau of China were analysed using a polyphasic approach. All four isolates were aerobic, short rod-shaped, non-motile, Gram-stain-positive, acid-fast and fast-growing. Phylogenetic analyses based upon 16S rRNA and whole-genome sequences showed that the two pair of strains formed two distinct branches within the evolutionary radiation of the genus .
