Several drugs that are effective in treating infections with VISA/VRSA have been approved by the Food and Drug Administration (FDA). A physician will decide which treatment is best, often in consultation with an infectious disease specialist.
What is VRSA in medicine?
Beta-lactam antibiotic (in combination) Vancomycin-resistant Staphylococcus aureus ( VRSA) are strains of Staphylococcus aureus that have become resistant to the glycopeptide antibiotic vancomycin.
When was the VRSA strain isolated?
Until 2002 such a genetic transfer was not reported for wild S. aureus strains. In 2002 , a VRSA strain ( / ˈvɜːrsə / or / viːɑːrɛseɪ /) was isolated from a patient in Michigan. The isolate contained the mecA gene for methicillin resistance.
What is the best treatment for methicillin-resistant Staphylococcus aureus?
For people with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in the setting of vancomycin failure the IDSA recommends high-dose daptomycin, if the isolate is susceptible, in combination with another agent (e.g. gentamicin, rifampin, linezolid, TMP-SMX, or a beta-lactam antibiotic).
Is S. aureus resistant to vancomycin?
High-level vancomycin resistance in S. aureus has been rarely reported. In vitro and in vivo experiments reported in 1992 demonstrated that vancomycin resistance genes from Enterococcus faecalis could be transferred by gene transfer to S. aureus, conferring high-level vancomycin resistance to S. aureus. Until 2002 such a genetic transfer was not reported for wild S. aureus strains. In 2002, a VRSA strain ( / ˈvɜːrsə / or / viːɑːrɛseɪ /) was isolated from a patient in Michigan. The isolate contained the mecA gene for methicillin resistance. Vancomycin MICs of the VRSA isolate were consistent with the VanA phenotype of Enterococcus species, and the presence of the vanA gene was confirmed by polymerase chain reaction. The DNA sequence of the VRSA vanA gene was identical to that of a vancomycin-resistant strain of Enterococcus faecalis recovered from the same catheter tip. The vanA gene was later found to be encoded within a transposon located on a plasmid carried by the VRSA isolate. This transposon, Tn 1546, confers vanA -type vancomycin resistance in enterococci.
Can vancomycin be transferred to S. aureus?
In vitro and in vivo experiments reported in 1992 demonstrated that vancomycin resistance genes from Enterococcus faecalis could be transferred by gene transfer to S. aureus, conferring high-level vancomycin resistance to S. aureus. Until 2002 such a genetic transfer was not reported for wild S. aureus strains.
Does Visa have resistance to Enterococcus?
Strains of hVISA and vancomycin-intermediate Staphylococcus aureus (VISA) do not have resistant genes found in Enterococcus and the proposed mechanisms of resistance include the sequential mutations resulting in a thicker cell wall and the synthesis of excess amounts of D-ala-D-ala residues. VRSA strain acquired the vancomycin resistance gene cluster vanA from VRE.

What is the best treatment for MRSA?
Vancomycin or daptomycin are the agents of choice for treatment of invasive MRSA infections [1]. Alternative agents that may be used for second-line or salvage therapy include telavancin, ceftaroline, and linezolid. Recent studies of treatment of MRSA bacteremia are reviewed. Vancomycin.
Is vancomycin good for MRSA?
Methicillin-resistant Staphylococcus aureus(MRSA) is a significant cause of health care-associated infections. Vancomycin remains an acceptable treatment option. There has been a welcome increase in the number of agents available for the treatment of MRSA infection.
Is MRSA a drug?
Methicillin- resistant Staphylococcus aureus(MRSA) is a common cause of serious nosocomial infections. Vancomycin, a glycopeptide in clinical use for more than 50 years, still serves as the cornerstone of the treatment of drug-resistant Gram-positive infections. However, there are significant concerns owing to decreasing susceptibility ...
Is vancomycin bactericidal?
aureus. Furthermore, vancomycin is slowly bactericidal, which may be partly responsible for reported clinical failures in treatment of bacteremia and endocarditis.
How long does telavancin last?
It is bactericidal against MRSA, vancomycin-intermediate S. aureus(VISA), and vancomycin-resistant S. aureus(VRSA). It has a half-life of seven to nine hours, permitting once daily dosing. Telavancin should be avoided in patients at risk for nephrotoxicity.
When was telavancin approved?
Telavancin was approved in November 2009 in the United States for the treatment of acute bacterial skin and skin structure infections (ABSSSI), and in June 2013 in US for hospital-acquired pneumonia (HAP) caused by gram-positive pathogens including MRSA where alternative treatments are not suitable.
Is telavancin effective for MRSA?
Telavancin may prove effective for treatment of MRSA bacteremia. In a phase 2 trial of telavancin for treatment of bacteremia including 17 patients, cure rates were comparable for telavancin and standard therapy (88 vs 89%) [8].
Can antibiotics help with MRSA?
Treatment. Both health care-associated and community-associated strains of MRSA still respond to certain antibiotics. Doctors may need to perform emergency surgery to drain large boils (abscesses), in addition to giving antibiotics. In some cases, antibiotics may not be necessary.
How to diagnose MRSA?
Doctors diagnose MRSA by checking a tissue sample or nasal secretions for signs of drug-resistant bacteria. The sample is sent to a lab where it's placed in a dish of nutrients that encourage bacterial growth. But because it takes about 48 hours for the bacteria to grow, newer tests that can detect staph DNA in a matter ...
Can antibiotics drain a boil?
Doctors may need to perform emergency surgery to drain large boils (abscesses), in addition to giving antibiotics. In some cases, antibiotics may not be necessary. For example, doctors may drain a small, shallow boil (abscess) caused by MRSA rather than treat the infection with drugs.
