“…related cultures suggesting that these microorganisms may colonize catheters and cause bacteremia from this focus (23). The species C. accolens, C. striatum, C. argentoratense, C. propinquum and C. pseudodiphtheriticum but not C. minutissimum were isolated mainly from blood samples in other opportunity (19).…”

“…Differences have been observed among Corynebacterium species most commonly recovered from human clinical materials by several authors (13,19,20,23). Over a 14-month period investigation, C. urealyticum, C. striatum, C. amycolatum and C. jeikeium predominated, accounting for 63% of 415 clinical isolates of coryneform Gram-positive rods recovered from various sources and identified to the species level according to recent identification schemes (19).…”

“…Because of the absence of accepted breakpoints for coryneform bacteria to interpretative categories, those established for Kirby-Bauer disk diffusion method by the NCCLS for organisms other than Haemophilus species and Neisseria gonorrhoeae were used by the authors. The breakpoints for Staphylococcus aureus were considered in the cases of penicillin, oxacillin and ampicillin (9,13,22,23).…”

“…catheters and their increased use, laboratories have experienced an increase in blood and catheter-related isolations of Gram-positive rods, often in quantities or repetitive isolations suggestive of potential clinical relevance. Emerging antimicrobial resistance in various species has created an additional need for accurate identification of corynebacteria organisms at the species level and continuous surveillance of their antimicrobial resistance patterns (19,23). The identification of aerobically growing Grampositive rods in a routine diagnostic laboratory presents several problems.…”

“…The increase in the number of reports concerning Corynebacterium infections may be due to better knowledge of taxonomy of these organisms, better identification schemes, and/or growing population of immunocompromised patients (10,11,12,19,23).…”

Over a five-year period, 163 strains of Corynebacterium sp. were recovered from different clinical specimens of patients from a Brazilian University hospital. Genitourinary tract and intravenous sites specimens were the most frequent sources of corynebacteria (46.62%). Corynebacterium amycolatum (29.55%), Corynebacterium minutissimum (20.45%) and Corynebacterium pseudodiphtheriticum (13.63%) were the predominant species found in genitourinary tract. C. minutissimum (24.14%) and Corynebacterium propinquum (17.24%) in surgical and/or other skin wounds and abscesses; Corynebacterium xerosis (25%), C. amycolatum (21.87%) and C. pseudodiphtheriticum (18.75%) in intravenous sites; C. pseudodiphtheriticum (33.33%) and C. propinquum (33.33%) in lower respiratory tract. Microorganisms were all susceptible to vancomycin and most of the species was predominantly resistant to β-lactams. Antimicrobial susceptibility patterns of corynebacteria were not predictable. Multiple antibiotic resistance observed in C. jeikeium was also found among C. xerosis, C. minutissimum, C. afermentans, C. propinquum, C. amycolatum and C. pseudodiphtheriticum strains. Data suggest awareness of clinicians and microbiologists to nosocomial infections especially due to antimicrobial multiresistant strains of Corynebacterium sp.

Co.ry.ne.bac.te'ri.um. Gr. n. coryne a club; L. neut. n. bacterium a rod, and in biology a bacterium (so called because the first ones observed were rod‐shaped); N.L. neut. n. Corynebacterium a club bacterium. Actinobacteria / Actinobacteria / Corynebacteriales / Corynebacteriaceae / Corynebacterium Straight to slightly curved rods with tapered ends. Rods are usually short or of medium length. Club‐shaped forms may be observed ; sometimes ellipsoidal, ovoid or rarely, “whip handles” (see below, Corynebacterium matruchotii ) or thinner rods with bulges (see below, Corynebacterium sundsvallense ) observed. Snapping division produces angular and palisade arrangements of cells. Gram‐stain‐positive; some cells stain unevenly . Metachromatic (synonym being polyphosphate) granules may be observed for some species. Not‐acid‐fast (Ziehl–Neelsen stain), and no species has aerial mycelium. Nonsporeforming. All species are nonmotile . All species are catalase positive . All species are oxidase negative except for Corynebacterium bovis, Corynebacterium aurimucosum, Corynebacterium doosanense , and Corynebacterium maris (below). Many species are facultatively anaerobic and some are aerobic . Chemoorganotrophs. Some species are lipophilic. Many species produce acid from glucose and some other sugars in peptone media. Several species alkalinize citrate as sole carbon sources, but most do not. DNA G+C content (mol%) : 46–74. Type species : Corynebacterium diphtheriae (Kruse 1886) Lehmann and Neumann 1896, 350 (“ Bacillus diphtheria ” Kruse in Flügge 1886, 225).
