Abstract

The genus Enterococcus consists of at least 12 species, two of which account for over 95% of the clinically important strains, E faecalis (85%-90%) and E faecium (5%-10%). Despite their ubiquity and frequent isolation, they have not been thought to cause serious disease because they lack common virulence factors. Now, however, enterococci are regarded as true pathogens and are the second leading cause of nosocomial infections. This change results from their increasing antimicrobial resistance and the extensive use of antimicrobial drugs (for example-cephalosporins) that are not active against them. Serious infections should usually be treated with a beta-lactam and an aminoglycoside, but glycopeptides have been increasingly used during the last decade. Two novel resistance patterns of particular concern recently are high level aminoglycoside resistance (HLAR) and vancomycin resistance. The prevalence of HLAR is between 15% and 55%, and glycopeptide resistance has become widespread in various geographical areas. This poses a serious problem, as such resistance may spread to other Gram-positive organisms and is often associated with resistance to other antimicrobial drugs. This may theoretically result in groups of organisms for ...Continue Reading

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Aminoglycosides (ASM)

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.
