If someone has a penicillin-resistant staph infection, is that the same as mrsa?

Not always. Mrsa stands for methicillin resistant staph aureus. Methicillin is a type of penicillin. Many species of staph bacteria are resistant to some forms of penicillin, but are sensitive to methicillin. Those bacteria are not classified as mrsa. Conversely, staph species that are resistant to methicillin are nearly always resistant to all the other penicillins as well.
No. It means that penicillin and Ampicillin do not work but the anti staph penicillins like methicillin and cephalosporins do.

What to do if I think my boyfriend gave me a mrsa/staph infection, how should I approach him about it?

B sure & don't fus . Many people have mrsa, u r exposed 2 it every day from just being around people in general. The reason there is a false stigma placed on those who have it is sad. It more important 2 know u have it or r a carrier than not. It is important not to enter hospitals or wear a mask 2 visit & he should not feel bad about it. If he were a surgical candidate every 1 is tested & rx'd b4 surg infec du 2=bad. Read more...

How can you tell MRSA from a regular staph infection?

Culture. A sample needs to be sent to a lab for testing to see which antibiotics successfully kill the bacteria. Mrsa means methicillin resistant staph aureus, methicillin is an antibiotic in the same class as penicillin. If methicillin doesn't work to kill the staph- it is labeled mrsa. Read more...
Culture. Mrsa is just a staph aureus that has a new gene that renders it resistant to beta-lactam antibiotics; for the most part, it will present the exact same as a "regular" staph infection, and will respond to other antibiotics the same as non-mrsa. It is difficult to call one regular because in most of the us, about 50% of all staph aureus is now mrsa. Only way to tell for sure is lab culture. Read more...

It is possible that a carrier of a staph infection reinfect my son who is MRSA colonized?

See below. Mrsa colonization means that your son is already infected with a staph bacteria. A colonization means that it is probably at only a low level. Staph aureus is one of the common bacteria that all people have on their skin. It becomes an infection when it overwhelms the body's defenses and caused problems. If a person has a staph infection it is possible that they can transmit this to any person. Read more...
Staph aureus. Colonization is not infection. You can possibly interrupt the carriage state using nasal Mupirocin ointment twice a day and washing only with soap containing chlorhexadine for a month or more. This will reduce or clear carriage state in about 50% of persons. It can be gotten again from others who touch you when they are colonized. Read more...
