Comamonas kerstersii (C. kerstersii) is a Gram-negative bacterium that was initially thought to be non-pathogenic to humans and is abundant in the environment. In recent years, with the availability of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) that enable fast and accurate bacterial identification, there have been increasing number of reports of human infections caused by C. kerstersii, indicating that this organism has emerged as human pathogen. In fact, most clinical isolates of C. kerstersii are recovered from peritoneal liquid, and bacteremia has been infrequently reported. Here, we report a case of bacteremia caused by C. kerstersii in a 28-year-old male patient with acute perforated appendicitis and localized peritonitis and present a comprehensive review of C. kerstersii infections in pathogenic diagnosis and clinical treatment as well as prognosis, thus providing a better understanding of C. kerstersii-related infections.

“…All of the patients were recovered after appropriate anti-infective therapy using metronidazole, piperacillin-tazobactam, and ceftriaxone etc. However, there were several cases of death that were associated with C. testosteroni , causing sepsis, purulent meningitis, and pneumonia ( 22 , 29 , 30 ).…”

Although some nomenclature changes have caused consternation among clinical microbiologists, the discovery of novel taxa and improving classification of existing groups of organisms is exciting and adds to our understanding of microbial pathogenesis. In this mini-review, we present an in-depth summary of novel taxonomic designations and revisions to prokaryotic taxonomy that were published in 2022. Henceforth, these bacteriology taxonomic summaries will appear annually. Several of the novel Gram-positive organisms have been associated with disease, namely, the Corynebacterium kroppenstedtii -like organisms Corynebacterium parakroppenstedtii sp. nov. and Corynebacterium pseudokroppenstedtii sp. nov. A newly described Streptococcus species, Streptococcus toyakuensis sp. nov., is noteworthy for exhibiting multi-drug resistance. Among the novel Gram-negative pathogens, Vibrio paracholerae sp. nov. stands out as an organism associated with diarrhea and sepsis and has probably been co-circulating with pandemic Vibrio cholerae for decades. Many new anaerobic organisms have been described in this past year largely from genetic assessments of gastrointestinal microbiome collections. With respect to revised taxa, as discussed in previous reviews, the genus Bacillus continues to undergo further division into additional genera and reassignment of existing species into them. Reassignment of two subspecies of Fusobacterium nucleatum to species designations ( Fusobacterium animalis sp. nov. and Fusobacterium vincentii sp. nov.) is also noteworthy. As was typical of previous reviews, literature updates for selected clinically relevant organisms discovered between 2017 and 2021 have been included.
