ORSA vs MRSA

So resistance does not run in the form of a drug "family'? One penicillin med may work while another would not? I did not realize resistance worked that way. I honestly thought if a bacteria was resistant to one penicillin drug, they would be resistant to all penicillin drugs. Where have I been? I'll climb out from under my rock now!

Allright, this made me curious so I looked up a little on wikipedia. ORSA is oxacillin resistant staph. MRSA should be methacillin resistant, but according to wiiki methicillin is rarely used clinically anymore, 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. Also, the term MRSA is sometimes used to describe ORSA.

Confusing, right? But yes, apparently a strain of staph can be resistant to just certain penicillins, not the whole class.

To answer the original question, "clindamycin is a lincosamide antibiotic used in the treatment of infections caused by susceptible microorganisms. Clindamycin is a semisynthetic antibiotic derived from lincomycin." I looked it up, it seems to be derived from yeast.

From what I remember, ORSA and MRSA are the same bacteria, just different names. ORSA, or oxacillin resistant staph aureus and MRSA, methicillin resistant staph aureus can be used interchangebly. Here is a link that I found regarding ORSA/MRSA..

When doctors order a culure and sensitivity of your sputum, it gives them very useful information regarding the treatment. First, the bacteria/fungi are identified next the sensitivities are found which describes what antibiotics the bacteria are sensitive to (and how sensitive to the antibiotic as well. Doctors will prescribe the antibiotic that will most effectively treat the bacteria) Sometimes, it is necessary to give more than one antibiotic, especially if the bacteria is very resistant (multi restistant or pan resistant- means resistant to everything). The theory is that by adding additional antibiotics, it causes a synergistic effect meaning that by adding those extra antibiotics, the treatment is much more intense on the bacteria.

Here is a link that describes sputum culture and sensitivity...

If you google synergistic effects with antibiotics, several articles will be found that describes this.

I hope that this has helped and not confused you! Hugs, Jenn <img src="i/expressions/face-icon-small-smile.gif" border="0">
