Many antibiotics are effective, including penicillin, erythromycin, clindamycin, rifampin, and tetracycline; erythromycin or penicillin is the treatment of choice and is usually given for 14 days.
Is Corynebacterium a normal flora?
Corynebacterium jeikeium is considered part of the normal skin flora, similar to S. epidermidis. This bacterium species resides on the skin of most humans and is commonly cultured from hospitalized patients.
Is Corynebacterium a good bacteria?
Additional corynebacteria include 45 species, 30 of which on rare occasion cause human disease. The nondiphtheria corynebacteria are increasingly recognized as agents of human disease in immunocompromised patients, and may also, although infrequently, infect healthy adults.
Is Corynebacterium a contaminant?
Corynebacteria are a bacteria usually associated as a contaminant due to their presence in normal human skin and mucosal membranes. However, they are increasingly becoming recognized as an opportunistic pathogen.

Among Corynebacterium jeikeium, strains were encountered that showed susceptibility to meropenem but resistance to imipenem and other beta-lactams. Strains of other corynebacteria, Rhodococcus equi, Erysopelothrix rhusiopathiae, Listeria monocytogenes, and Bacillus spp.
How do you get Corynebacterium?
Corynebacterium diphtheriae is spread by droplets, secretions, or direct contact. In situ lysogenic conversion of nontoxigenic strains to a toxigenic phenotype has been documented. Infection is spread solely among humans, although toxigenic strains have been isolated from horses.
Can Corynebacterium cause a UTI?
Corynebacterium urealyticum is a cause of urinary tract infection and encrusting cystitis or pyelitis.
What part of the body does Corynebacterium colonize?
Most commonly affected areas include heart, muscle, peripheral nerves, adrenal glands, kidneys, liver, and spleen (rather comprehensive).
What does Corynebacterium do to the body?
Diphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheriae that make toxin (poison). It can lead to difficulty breathing, heart failure, paralysis, and even death. CDC recommends vaccines for infants, children, teens, and adults to prevent diphtheria.
How is Corynebacterium useful?
Nonpathogenic species of Corynebacterium are used for important industrial applications, such as the production of amino acids, nucleotides, and other nutritional factors (Martín, 1989); bioconversion of steroids; degradation of hydrocarbons; cheese aging; and production of enzymes.
Where is Corynebacterium Jeikeium found?
jeikeium is found in soil and water and is part of normal human skin flora. The colonization rate increases with hospitalization; it has been reported in hospital personnel and in up to 40% of hospitalized patients, especially on the skin of the perirectal area, groin, and axilla.
What is the most common contaminant of blood cultures?
In the past, coagulase-negative staphylococci were usually believed to represent contamination when isolated from blood cultures. In fact, coagulase-negative staphylococci are the most common blood culture contaminants, typically representing 70% to 80% of all contaminated blood cultures (25, 92, 105, 113, 125).
What antibiotic is used to treat Gram-positive cocci?
Daptomycin, tigecycline, linezolid, quinupristin/dalfopristin and dalbavancin are five antimicrobial agents that are useful for the treatment of infections due to drug-resistant Gram-positive cocci.
Can Enterococcus be a contaminant?
Enterococci are a common cause of bacteremia but are also common contaminants. In our institution, approximately 17% of positive blood cultures with enterococci are mixed with skin organisms. Such isolates are probable contaminants.
Does Rocephin cover Corynebacterium?
Based on CLSI M45 breakpoint criteria for Corynebacterium, highest resistance rates were observed for ciprofloxacin (73.7%), followed by trimethoprim/sulfamethoxazole (71.6%), erythromycin (65.5%) and ceftriaxone (63.6%; Table 2).
Does linezolid treat Corynebacterium?
Results: Linezolid was very active against the 130 strains of the Corynebacterium species studied. Only the glycopeptides showed similar efficacy. In contrast, penicillin G, ampicillin, macrolides, lincosamides, fluoroquinolones and aminoglycosides showed generally high MICs.
How do you treat Corynebacterium Minutissimum?
The treatment of choice is erythromycin 250 mg four times daily for 2 weeks. Topical clindamycin twice daily also can be used. For severe cases, a combination of oral erythromycin and topical antibiotics may be needed. Recurrence can be minimized by the use of an antibacterial soap.
Does meropenem cover MSSA?
spectrum: meropenem. Gram-positives: Generally very good (including MSSA, Enterococcus faecalis, Staph.
Is meropenem a bactericidal?
Furthermore, meropenem was bactericidal for Pseudomonas spp., including Ps. (Xanthomonas) maltophilia, and staphylococci, with MBCs on average only two-fold above the respective MICs. The bactericidal activity was confirmed by killing curve assays.
What covers tigecycline?
Coverage includes many multidrug-resistant strains of gram-positive organisms, such as MRSA and MRSE, penicillin-resistant Streptococcus pneumoniae, and VRE species. Tigecycline has also shown activity against organisms that have developed resistance to tetracycline via various mechanisms.
What diphtheria smells like?
Infectious diseases were known by their characteristics odors–scrofula as smelling like stale beer; typhoid, like freshly baked brown bread; rubella, like plucked feathers; and diphtheria, as sweetish. Anosmics might be banned from medical school.
Will diphtheria go away on its own?
That’s because immunity to diphtheria fades with time. Children who received all of the recommended immunizations before age 7 should receive their first booster shot at around age 11 or 12.
Where is diphtheria most commonly found?
Since 2016, respiratory diphtheria outbreaks have occurred in Indonesia, Bangladesh, Myanmar, Vietnam, Venezuela, Haiti, South Africa, and Yemen. Cutaneous diphtheria is common in tropical countries. Respiratory and cutaneous diphtheria have been reported in travelers, though rarely.
What is encrusted cystitis?
Encrusted cystitis (EC) is a rare condition defined by bladder mucosal struvite calcifications. First reported in 1914, EC is caused by urea-splitting bacteria, often Corynebacterium urealyticum. 1. This member of skin flora is present in 12% of the population.
What is Corynebacterium striatum sensitive to?
striatum exhibited 100% susceptibility to vancomycin, linezolid, teicoplanin, piperacillin-tazobactam, amoxicillin-clavulanate and cefuroxime, while strains of this bacterium showed a high degree of resistance to fluoroquinolones, the vast majority of β-lactams, aminoglycosides, macrolides, lincosamides and …
What are Diphtheroids in urine?
Diphtheroids are defined as aerobic, non-sporulating, pleomorphic Gram-positive bacilli which are more uniformly stained than Corynebacterium diphtheriae, lack the metachromatic granules and are arranged in a palisade manner. They are usually commensals of the skin and mucous membranes.
What does Corynebacterium Xerosis cause?
Corynebacterium xerosis is a commensal organism normally present in skin and mucous membranes of humans and animals [1]. It is considered an unusual pathogen but it is able to cause endocarditis, skin infections and other illnesess [1–6].
What are rods with square ends?
Bacillus anthracis is a large (1–1.5×3–10 μm) gram-positive sporulating rod, with square or concave ends.

The genus Corynebacterium is composed of a wide variety of Gram-positive, non-acid-fast, nonmotile, rod-shaped, catalase-positive bacteria. The bulk of the species is considered to be normal cutaneous, pharyngeal and gastrointestinal flora of humans.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
