Hidden from plain sight: Novel Simkaniaceae and Rhabdochlamydiaceae diversity emerging from screening genomic and metagenomic data
Syst Appl Microbiol. 2023 Sep 23;46(6):126468. doi: 10.1016/j.syapm.2023.126468. Online ahead of print.ABSTRACTChlamydiota are an ancient and hyperdiverse phylum of obligate intracellular bacteria. The best characterized representatives are pathogens or parasites of mammals, but it is thought that their most common hosts are microeukaryotes like Amoebozoa. The diversity in taxonomy, evolution, and function of non-pathogenic Chlamydiota are slowly being described. Here we use data mining techniques and genomic analysis to extend our current knowledge of Chlamydiota diversity and its hosts, in particular the Order Parachlamy...

Mycoplasma bradburyae sp. nov. isolated from the trachea of sea birds
Syst Appl Microbiol. 2023 Oct 7;46(6):126472. doi: 10.1016/j.syapm.2023.126472. Online ahead of print.ABSTRACTIn the search for mollicutes in wild birds, six Mycoplasma strains were isolated from tracheal swabs taken from four different species of seabirds. Four strains originated from three Yellow-legged gulls (Larus michahellis) and a Cory's shearwater (Calonectris borealis) from Spain, one from a South African Kelp gull (Larus dominicanus), and one from an Italian Black-headed gull (Chroicocephalus ridibundus). These Mycoplasma strains presented 99 % 16S rRNA gene sequence similarity values with Mycoplasma (M.) gallisep...

Halapricum hydrolyticum sp. nov., a beta-1,3-glucan utilizing haloarchaeon from hypersaline lakes
Syst Appl Microbiol. 2023 Oct 7;46(6):126471. doi: 10.1016/j.syapm.2023.126471. Online ahead of print.ABSTRACTTwo strains of neutrophilic haloaloarchaea were selectively enriched from hypersaline lakes in southwestern Siberia using β-1,3-glucans as a substrate. The strains were nearly identical in their phenotypes and according to phylogenomic analysis, and represent a distant novel species group in the genus Halapricum of the family Haloarculaceae. The main phenotypic property of the novel isolates is the ability to hydrolyze and grow with the polysaccharides curdlan and pachyman. Such potential has, to date, not been se...

Two novel symbiovars of Bradyrhizobium yuanmingense, americaense and caribense, the symbiovar tropici of Bradyrhizobium pachyrhizi and the symbiovar cajani of Bradyrhizobium cajani are microsymbionts of the legume Cajanus cajan in Dominican Republic
Syst Appl Microbiol. 2023 Sep;46(5):126454. doi: 10.1016/j.syapm.2023.126454. Epub 2023 Sep 4.ABSTRACTCajanus cajan L. (guandul) is commonly cultivated in Dominican Republic where this legume is a subsistence crop. Here we identified through MALDI-TOF MS several rhizobial strains nodulating C. cajan in two Dominican locations as Bradyrhizobium yuanmingense. The phylogenetic analysis of recA and glnII housekeeping genes showed that these strains belong to a wide cluster together with the type strain of B. yuanmingense and other C. cajan nodulating strains previously isolated in Dominican Republic.
