Hi, could anyone tell me if it is possible to ascertain if a staphylococcus hominis infection is nosocomial or community acquired by its resistance/ sensitivity to anti-microbals

thank you!

I think it would make sense that hospital-acquired are resistant to a greater number of antimicrobials because in a hospital setting there's a lot more antimicrobials being used. Not a definitive test though.

It might in acute sense - linking it to specific isolates from the hospital in question but there are certainly better ways to demonstrate the connection. There are both community and hospital acquired MRSA.

This is with regards to staph hominis sp hominis, it has been noted that a lot of medical workers can be temporarily colonised with this bacteria due to the constant handwashing leading to damaged skin. I was also wondering if tis staph bacteria is a true pathogen.

There is a link between antibiotics resistence and HAI. Superbugs is described in hospital

Just by looking at resistance profiles it is pretty much impossible to ascertain the source with any measure of accuracy. Or in other words, the resistance profile alone is a poor predictor.

Almost definitely not. Antibiotic resistance is often reported within a year of release of a new drug, and that spreads fairly rapidly. The best that could be accomplished is to determine probability of acquisition from a hospital environment, but you'd need information that isn't public to figure out the odds.

I think joining a pre-med forum is much more productive for this sort of thing.

A lot of MDs frequent these places and help the students.

Ive heard about that colonization especially fire brigade which are usually first help in traffic accident. When happened something serious epidemiological investigation is conducted of course with genotyping. It was when nurse was infected newborns. In your case oportunity could be acquired, its difficult to say that it is bacteria from hospital if it isnt a typical like super bacteria. S. hominic could be even on the hospital pillow. In my country every strain of staphylococcus which is resistant for usually used antibiotics must be send to special repherence center.
