Summary: The genus Clostridium is diverse and includes species like C. cocleatum, C. ramosum, C. spiroforme, and C. saccharogumia. These species form a distinct cluster within the family Coprobacillaceae in the order Erysipelotrichales. Based on phylogenetic, genomic, phenotypic, and chemotaxonomic information, it is proposed that these species be transferred to a new genus called Thomasclavelia.

Summary: Polyphasic studies in Iran focused more on filamentous cyanobacteria, with scarce research on unicellular cyanobacteria. A new genus and species, Alborzia gen. nov. and Alborzia kermanshahica sp. nov., were proposed based on morphological, ecological, and phylogenetic analyses, demonstrating uniqueness and distinction from existing genera in the Chroococcales. This study contributes to the understanding and diversity of unicellular cyanobacteria in paddy fields in Iran.

Summary: This study characterized nine strains of Clavibacter michiganensis subsp. michiganensis isolated in Chile, revealing differences in virulence. Two highly virulent strains showed increased cellulase activity, while a strain causing mild symptoms had no cellulase activity. PCR and gene sequence analysis indicated correlations between disease severity differences and the presence/absence of specific genes. Deletions in virulence genes were also observed in the Chilean strains.

Summary: The study describes a thermophilic, strictly anaerobic, Gram-stain-negative bacterium strain S15T isolated from oily sludge in Shengli oilfield, China. Physiological characteristics, ecological information, and taxonomical classification of strain S15T are discussed, leading to the proposal of a new genus and species, Thermosynergistes pyruvativorans gen. nov., sp. nov. with strain S15T as the type strain. Additionally, a new family, Thermosynergistaceae fam. nov., is suggested based on the unique characteristics of the strain.

Summary: With improvements in genomics, it is now possible to accurately identify clinical isolates at the species level and analyze past occurrences of specific organisms. This approach can aid in the classification of clinically relevant taxa that have previously gone unrecognized in clinical diagnostics.

Summary: In this study, a Gram-stain-positive acetogen, strain P21(T), was isolated from old hay. Phylogenetic analysis confirmed its close relationship with three Clostridium species. Strain P21(T) can utilize various substrates and produces acetate, butyrate, caproate, ethanol, and hexanol as end products. Its unique characteristics support its classification as a new species, named Clostridium muellerianum sp. nov.

Summary: Two Legionella-like strains isolated from hot water distribution systems in 2012 were characterized phenotypically, biochemically, and genomically. The analysis based on various methods, including 16S rRNA gene sequences and comparative genome sequence-based analyses, confirmed that these strains represent a new species of the genus Legionella. The name Legionella maioricensis sp. nov. is proposed for this novel species.

Summary: In this study, Shewanella baltica strains isolated from the gut contents of wild Atlantic mackerel were analyzed using whole-genome sequencing. The study identified new variants of antibiotic resistance genes and found the presence of the mobile colistin resistance gene mcr-4.3 in a significant proportion of the strains. The analysis of the complete genome sequence of one strain further revealed the presence of multiple plasmids carrying different resistance genes. This study provides insights into the genetic diversity and mobility of antibiotic resistance genes in Shewanella spp., highlighting the importance of the marine environment in the emergence and dissemination of clinically important resistance genes.
