Where is Gordonia found?
Gordonia spp., previously classified as Rhodococcus spp., are ubiquitous in the environment, and often are found in soil and water.
What is Nocardioform?
Nocardioforms are filamentous, Gram positive actinomycete bacteria that can cause persistent and excessive foaming in activated sludge plants during the summertime.
Is Rhodococcus gram-positive or negative?
Microbiology. Rhodococcus (Corynebacterium) equi is a gram-positive, encapsulated, intracellular bacillus, varying from coccoid to long and club-shaped.
Is Rhodococcus acid-fast?
Rhodococcus equi is an aerobic Gram-positive and acid-fast coccobacillus that may cause cavitary pneumonia in immunocompromised hosts such as HIV-infected patients.
What is Nocardioform Placentitis?
Nocardioform placentitis is an equine placental disease affecting pregnant mares and their foals during pregnancy.
What is Gordonia spp?
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.
How is Gordonia (Rhodococcus) spp diagnosed?
Microbiologic diagnosis of Gordonia spp. remains difficult. Biochemical profiles can lead to incorrect identification of isolates as Rhodococcus spp. ( 2, 4 – 6, 9) and sometimes Corynebacterium spp. ( 3) or Nocardia spp. ( 6 ). Identification at the genus and species levels is presently obtained by 16S rRNA sequence comparisons.
Is Gordonia spp resistant to vancomycin?
Antimicrobial drug susceptibility is similar to that of Rhodococcus spp., for which Gordonia spp. are usually incorrectly identified. However, although vancomycin is often used to treat Rhodococcus spp. infections, in a previous study 11% of Gordonia spp. isolates were resistant ( 6 ).
What are the treatment options for Gordonia infections in children?
Catheter removal has been recommended for treatment of Gordonia spp. infections in children ( 6 ), but the recommendation varied for adults. Six cases of infection in children have been described ( 6 ), appearing as bacteremia, ventriculitis, and brain abscess. Microbiologic diagnosis of Gordonia spp. remains difficult.
