MRSA bacteria are pathogenic, this is the name given to a group of bacteria that belong to the Staphylococcus aureus family of bacteria which have grown resistant to methicillin-type antibiotics. MRSA stands for:
Methicillin-resistant Staphylococcus aureus.
Staphyloccocus aureus bacteria are often carried on people's skin and sometimes in their noses and back of their throats. People carrying the bacteria who are healthy are said to be colonized, but not infected. The bacteria, however, can cause serious infections, such as pneumonia, blood, bone and surgical wound infections, as well as less serious infections such as impetigo, cellulitis and small abscesses or boils under the right conditions.

No. Almost all bacteria are not. There are bacteria everywhere performing essential functions like breaking down dead animals and plants. Bacteria are essential to health helping digest food and preventing pathogenic bacteria from getting out of control.
"Pathogen" is something that gives rise to disease or infection. There are bacteria that do not do these things though, such as the culture in yogurt or the E.coli already residing in your stomach.
Firstly, pathogenic is not the opposite of anaerobic. The vast majority of bacteria are non-pathogenic, but this doesn't mean they are anaerobic.
We hear more about Gram-negative pathogens (E. coli, Salmonella, etc.) because they make good news stories and are generally associated with transmission in improperly handled or prepared food. However, there are many pathogenic Gram positive bacteria as well - Staphlococcus (including MRSA), Streptococcus (such as strep throat), etc. Also, there are many Salmonella species that are non-pathogenic, as well as non-pathogenic E. coli, Enterobacteraceae, etc. So I'm not sure that most Gram negative bacteria are pathogenic.
Non-pathogenic organisms are not harmful to humans and do not cause disease. Some non-pathogenic bacteria can even be beneficial, such as those found in the gut that aid in digestion.
You can find non-pathogenic freeze-dried Staphylococcus bacteria with growth medium from scientific supply companies or online biological supply stores. These companies offer a variety of non-pathogenic bacterial strains for research and educational purposes. Make sure to follow appropriate safety protocols when working with bacteria in a lab setting.
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.
Non-pathogenic bacteria are bacteria that do not cause disease or harm to their host organism. They can exist in various environments, including the human body, without causing any negative effects. Some non-pathogenic bacteria may even provide benefits, such as aiding in digestion or producing essential vitamins.

Nobody knows. you should ask some nerd.
