| | Methicillin - Wikipedia, the free encyclopedia |
 | | Methicillin is not commonly used in clinical practice, but serves a purpose in the laboratory to determine antibiotic sensitivity in microbiological culture. | | | Its role in therapy has been largely replaced by flucloxacillin and dicloxacillin, however the term methicillin-resistant Staphylococcus aureus (MRSA) continues to be used to describe Staphylococcus aureus strains resistant to all penicillins. | | | It is previously used to treat infections caused by susceptible Gram-positive bacteria, particularly beta-lactamase-producing organisms such as Staphylococcus aureus that would otherwise be resistant to most penicillins, but is no longer clinically used. |

| | Tests done on any Staphylococcus Aureus grown from such specimens can then decide how sensitive the organisms is to antibiotics and if it is a Methicillin resistant (MRSA) organism. | | | However, antibiotics, such as Methicillin and Flucloxacillin, are not yet affected by this ß-lactamase and can still be used to treat many infections against ß-lactamase-producing strains of Staphylococcus Aureus. | | | Unfortunately, certain strains of Staphylococcus Aureus, known as MRSA, which should be referred to as the Hyperbug, have now evolved further, also to become resistant to treatment with Methicillin and Flucloxacillin. |

| | Postgraduate Medicine: Containing methicillin-resistant S aureus |
| | Methicillin was among the first of these agents to be introduced into clinical practice, but strains of MRSA were identified as early as 1961. | | | The performance of these tests may be erratic because factors such as inoculum size and variability in culture conditions may affect phenotypic expression of resistance. | | | Most MRSA strains are heterogeneously resistant to methicillin, so only a small proportion of the S aureus colonies that grow from a clinical specimen may show resistance in standard laboratory tests. |

| | Methicillin is an antibiotic which is sensitive to physical pressures like temperatures. | | | It is important to note that clinical laboratories do not use the methicillin antibiotic for direct susceptibility testing (often referred to incorrectly as sensitivity testing). | | | C change in temperature can result in a false negative reaction. |

| | Methicillin-resistant Staphylococcus aureus - Wikipedia, the free encyclopedia |
| | Methicillin-resistant Staphylococcus aureus (MRSA) is a specific strain of the Staphylococcus aureus bacterium that has developed antibiotic resistance to all penicillins, including methicillin and other narrow-spectrum β-lactamase-resistant penicillin antibiotics. | | | They have slightly raised minimum inhibitory concentrations (MICs) and may thus be described as "minimally resistant". | | | aureus over-express β-lactamase and appear to be resistant to oxacillin and, rarely, methicillin despite being mecA-negative. |
