Characterization of clinical Enterococcus faecalis small-colony variants.
In this report, we present a clinical case of chronic aortic valve endocarditis caused by Enterococcus faecalis small-colony variants (SCVs), with ensuing characterization of the SCV phenotype in comparison to the clonally related normal phenotype with respect to alterations in microscopic and ultrastructural morphology, growth behavior, and metabolic pathways. In contrast to the normal phenoty...
متن کاملCharacterization of small-colony variants of Enterococcus faecalis isolated from chickens with amyloid arthropathy.
In this study we report the isolation and characterization of normal-sized and small-colony variants of Enterococcus faecalis from outbreaks of amyloid arthropathy in chickens. Postmortem examinations of 59 chickens revealed orange deposits in the knee joints, typical for amyloid arthropathy. Bacterial cultures from 102 joints and 43 spleens exhibited pure (n = 88) and mixed (n = 11) cultures o...
متن کاملCharacterization of vancomycin resistance in Enterococcus faecium and Enterococcus faecalis.
Vancomycin resistance in Enterococcus faecium 180, a clinical isolate from England, was studied. Resistance to vancomycin was transferable by conjugation to other enterococci. Expression of resistance was inducible and coincided with the appearance of a new membrane protein.
متن کاملCharacterization of monolaurin resistance in Enterococcus faecalis.
There is increasing concern regarding the presence of vancomycin-resistant enterococci in domestically farmed animals, which may act as reservoirs and vehicles of transmission for drug-resistant enterococci to humans, resulting in serious infections. In order to assess the potential for the use of monolaurin as a food preservative, it is important to understand both its target and potential mec...
متن کاملIsolation and characterization of small-colony variants of Ornithobacterium rhinotracheale.
Ornithobacterium rhinotracheale is a Gram-negative bacterium associated with respiratory diseases in many avian species, with worldwide distribution, and it causes significant economic loss to the poultry industry. In this study, the isolation and characterization of O. rhinotracheale small-colony variants (SCVs) are described for the first time. O. rhinotracheale isolates (n = 27) were recover...
