Is gordonia a mycobacterium?
Gordonia is a genus of gram-positive, aerobic, catalase-positive bacterium in the Actinomycetota, closely related to the Rhodococcus, Mycobacterium, and Nocardia genera. It is from the same lineage that includes Mycobacterium tuberculosis.
What is gordonia Sputi?
Gordonia spp. are environmental bacteria whose implication in human disease seems to be increasing. Phenotypic identification of bacteria included in this genus is difficult, and they are often poorly identified as Rhodococcus spp. or Corynebacterium spp. Molecular identification of Gordonia spp.
What is gordonia Bronchialis?
Gordonia bronchialis is the identified species in only a minority of human infections due to Gordonia spp. and rarely a cause of bacteremia. In our review of the literature, we identified 30 other reported cases of Gordonia bloodstream infections, with only 2 of these due to G. bronchialis (Table 2).
What is gordonia Terrae?
Gordonia terrae, which was previously known as “Gordona terrae” and “Rhodococcus terrae,” is a nocardioform actinomycete originally isolated from soil and from the sputum samples of patients with pulmonary disease [1–3].
Where is gordonia found?
Gordonia species are typically found in soil and aquatic habitats, but a growing number of Gordonia species are becoming associated with human and animal diseases [4] . In all known cases of infection by Gordonia species, patients were immunosuppressed and infection occurred subsequent to illness.
Where does gordonia Terrae grow?
China
Gordonia terrae is a non-motile Gram positive Actinobacterium in the family Gordoniaceae. The ATCC strain 25594 is G. terrae C-6 and is sequenced. It is a benzothiophen-desulfuring bacterium isolated from oil-contaminated soil of the GuDao Oile filed, China.
Is gordonia acid fast?
Gordonia species are Gram-positive, partially acid-alcohol fast, catalase-positive, aerobic, chemoorganotrophic mycolic acid–containing coccobacillary actinomycetes with high G + C contents in their DNA (63–69%).
What is Corynebacterium Tuberculostearicum?
Introduction: Corynebacterium tuberculostearicum (C. t.) is a ubiquitous bacterium that colonizes human skin. In contrast to other members of the genus Corynebacterium, such as toxigenic Corynebacterium diphtheriae or the opportunistic pathogen Corynebacterium jeikeium, several studies suggest that C.
Where does Corynebacterium come from?
Habitat. Corynebacterium species occur commonly in nature in soil, water, plants, and food products. The nondiphtheiroid Corynebacterium species can even be found in the mucosa and normal skin flora of humans and animals.
What is Corynebacterium Riegelii?
Given the name Corynebacterium riegelii, it is nonlipophilic, weakly fermentative, and facultatively anaerobic. Similar to the lipophilic C. urealyticum, it demonstrates strong urease activity. It is susceptible to penicillins, cephalosporins, gentamicin, fluoroquinolones, rifampin, and tetracyclines.
How serious is Corynebacterium?
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.
What part of the human body does Corynebacterium colonize?
Most commonly affected areas include heart, muscle, peripheral nerves, adrenal glands, kidneys, liver, and spleen (rather comprehensive). The diphtheria toxin works by causing the death of eukaryotic cells and tissues by inhibiting protein synthesis in the cells. Two key factors aid C.
How many cases of gordoniabloodstream infections are there?
In our review of the literature, we identified 30 other reported cases of Gordoniabloodstream infections, with only 2 of these due to G. bronchialis(Table 2).
Is endocarditis caused by Gordonia Sputi a new pathogen?
We report the first case of endocarditis caused by a Gordonia species genetically related to G. sputi but exhibiting some atypical biochemical features in a 31-year-old woman with a central venous catheter. This unusual pathogen may be a new cause of opportunistic infections in patients with severe underlying diseases.
Does Gordonia bronchialisbacteremia require an indwelling intravascular catheter?
We describe a case of Gordonia bronchialisbacteremia and pleural space infection in the absence of an indwelling intravascular catheter and review the breadth of reported infections with this emerging pathogen. CASE REPORT
What is the prognosis of gordoniaspecies infections?
The number of recognized infections due to Gordoniaspecies may rise in the future because of the increased use of long-term indwelling central venous catheters, the extended survival of immunocompromised patients, and improved laboratory identification methods.
