Diphtheroids-Important Nosocomial Pathogens [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: Diphtheroids are defined as aerobic, nonsporulating, pleomorphic Gram-positive bacilli which are more uniformly stained than Corynebacterium diphtheriae, lack the metachromatic granules and are arranged in a palisade manner.

Draft genome and description of Corynebacterium haemomassiliense strain Marseille-Q3615T sp. nov., a new bacterium isolated from a 59-year-old man with chronic obstructive pulmonary disease symptoms

New Microbes and New Infections, 2020
In 2020, as part of a diagnosis attempt at IHU Méditerranée Infection in Marseille (France), a blood specimen was obtained from a 59-year-old man with chronic obstructive pulmonary disease symptoms, from which we isolated the new bacterial ...

Reclassification of Corynebacterium flaccumfaciens, Corynebacterium betae, Corynebacterium oortii and Corynebacterium poinsettiae in the genus Curtobacterium, as Curtobacterium flaccumfaciens comb. nov.

Microbiology, 1983
Summary: The phytopathogens Corynebacterium flaccumfaciens (Hedges), Corynebacterium betae (Keyworth, Howell & Dowson), Corynebacterium oortii (Saaltink & Maas Geesteranus) and Corynebacterium poinsettiae (Starr & Pirone) differ to such an extent from the type species of Corynebacterium, Corynebacterium diphtheriae (Lehimann & Neumann), that they ...

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

Advanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

NGS-based phylogeny of diphtheria-related pathogenicity factors in different Corynebacterium spp. implies species-specific virulence transmission

BMC Microbiology, 2019
Diphtheria toxin (DT) is produced by toxigenic strains of the human pathogen Corynebacterium diphtheriae as well as zoonotic C. ulcerans and C. pseudotuberculosis.

Non-toxigenic Corynebacterium diphtheriae in hallux ulceration

Journal of Infection in Developing Countries, 2022
Introduction: Toxigenic Corynebacterium diphtheriae causes classical diphtheria. Skin infections by toxigenic or non-toxigenic Corynebacterium diphtheriae are prevalent in the tropics but are rarely reported.

A novel multiparameter sensor for shake flask cultivations: Online biomass, dissolved oxygen, and fluorescence monitoring for comprehensive bioprocess characterization

Biotechnology Progress, EarlyView.
Abstract Shake flasks are one of the most widely used cultivation vessels in biotechnological process development. To improve the process understanding, new technologies have been reported for online monitoring of different parameters like oxygen, pH, or biomass in the last couple of years.

The Herbal Pair <i>Polygonum hydropiper</i> <i>L-Coptis chinensis Franch</i> Attenuate DSS-Induced Ulcerative Colitis by Modulating Metabolism and Intestinal Flora. [PDF]

Food Sci Nutr
PH‐CC regulates dysbiosis in intestinal flora and metabolic disorders in UC mice by reducing the abundance of specific bacterial groups, thereby alleviating inflammatory damage to the colonic mucosa and improving the overall condition of UC. ABSTRACT Ulcerative colitis (UC) is a chronic inflammatory bowel disease in which dysbiosis of the intestinal ...

In Vivo Biosynthesis and Direct Incorporation of Non‐Canonical Amino Acids into Proteins

ChemBioChem, Accepted Article.
Autonomous cells are engineered biological systems capable of biosynthesising and directly incorporating non‐canonical amino acids (ncAAs) into proteins. These systems have the potential to extend the applicability of the genetic code to enable large‐scale fermentative production of proteins carrying ncAAs.

Evolutionary engineering of Corynebacterium glutamicum

Biotechnology Journal, 2019
A unique feature of biotechnology is that we can harness the power of evolution to improve process performance. Rational engineering of microbial strains has led to the establishment of a variety of successful bioprocesses, but it is hampered by the ...
