Leprosy-derived corynebacteria (LDC) have been extensively studied over the past decade. A composite of their biological properties (cell morphology, staining reactions, cellular inclusions and guanine-plus-cytosine content of their deoxyribonucleic acid; 16 strains studied) and their chemical structures (peptidoglycan type, major cell wall polysaccharide, major glycolipid as well as characteristic mycolic acids) appears to define them as members of the genus Corynebacterium. In relation to other corynebacteria found in humans, including "JK corynebacteria", they seem to be distinct. They are here named Corynebacterium tuberculostearicum sp. nov. because they produce a 10-methyloctadecanoic (tuberculostearic) acid (8 strains studied). This and some of their other attributes are considered in relation to properties of leprosy bacilli and Mycobacterium leprae.

Introduction: species other than are being continuously reported as pathogens.
Case Presentation: A patient visited the Urology Outpatient Department of a tertiary care centre in India reporting lower abdominal pain, urinary incontinence, and intermittent weak urine flow persisting for 12 years, intensifying over the last 15 days. She also experienced urgency, straining, weak stream, and incomplete voiding, along with a previous fever episode.

Determining the source of body fluids is crucial in forensic investigations, as it provides valuable information about suspects and the nature of the crime. Microbial markers that trace the source of tissues and body fluids based on site specificity and temporal stability are often used effectively for this purpose. In this study, a multiplex system comprising seven microbial markers (Finegoldia magna, Corynebacterium tuberculostearicum, Cutibacterium acnes, Haemophilus parainfluenzae, Streptococcus oralis, Prevotella melaninogenica and Faecalibacterium prausnitzii) was developed to distinguish between skin, saliva, and feces samples.

Melanin is produced by melanocytes to protect human skin from harmful ultraviolet radiation. During skin cell renewal, melanin and dead skin cells are disposed of. However, prolonged exposure to ultraviolet rays or aging can disturb this cycle, leading to skin hyperpigmentation due to melanin accumulation.

Unlabelled: This study performed microbial analysis of nutrient film technique (NFT) hydroponic systems on three indoor farms in Singapore (the "what"). To justify the necessity of sanitizing hydroponic systems, strong biofilm-forming bacteria were isolated from the facility and investigated for their influence on colonization on polyvinyl chloride (PVC) coupons in hydroponic nutrient solutions (the "why"). Finally, sanitization solutions were evaluated with both laboratory-scale and field-scale tests (the "how").
