Has anyone ever had the super bug ( staph ) and treated it with amoxacillin?

AMOXICILLIN/STAPH IN: Amoxicillin is a drug of choice for beta lactamase negative bacteria, and is quite effective normally when we suspect staph infetion we do not use Amoxicillin because we do not know if the it is staph coagulase neg or positive but in reality it is a good antibiotic for coagulase negative staph. ...Read more

Can you clarify what methicillin resistant staphylococcus aureus really is?

Can you clarify what methicillin resistant staphylococcus aureus really is?

What it says: Mrsa is exactly what it says it is: a strain of staph. Aureus that is resistant to the antibiotic methicillin. The reason this is such a big deal is that methicillin was, for many years, the sovereign treatment for staph aureus - and when a strain emerged that was resistant to it, it caused quite a stir. But there are (for now) effective treatments, including Doxycycline and bactrim (sulfamethoxazole and trimethoprim). ...Read more

What are the differences between MRSA (methicillin-resistant staphylococcus aureus) or c-diff (clostridium difficile)?

Clostridium difficile causes disease by overgrowth in the intestinal lumen and producing toxins that injure the colonic mucosa causing diarrhea and colitis. ...Read more

Resistant to therapy: Mrsa is a form of staph aureus that can come in 2 forms, community aquired and hospital acquired. The bacteria will be resistant to penicillins that are used to treat MRSA including methicillin and oxacillin. There can still be oral choices for treatment as long as the infection is not severe. ...Read more

What type of bacterial infection is methicillin resistant staphylococcus aureus (mrsa)?

A bad type.: Mrsa is a potent strain of staph bacteria that worries doctors because it is resistant to the antibiotic methicillin, which for many years was the single best treatment for staph infections. It is usually treatable with other antibiotics, such as Bactrim (sulfamethoxazole and trimethoprim) or doxycycline, but such infections can be very virulent and contagious. ...Read more

Could i get a boob job if I have nonactive methicillin-resistant staphylococcus aureus (mrsa)?

MRSA : Mrsa once was a rare finding most often seen in the hospital setting. This is not the case, as MRSA is now almost universal. Many people are chronic carriers of the MRSA organism. If you are non-active, i feel that you could have breast augmentation. Pre-op you should consider nasal swab antibiotics, PO antibiotics and antibacterial body washes. This should reduce your chances for infection. ...Read more

See ID specialist: There may be several reasons that the staph infection returns - 1) that the bacteria is resistant to the antibiotics given (particularly true with methicillin resistant staph aureus - also known as mrsa); 2) that there is an underlying site or foreign body that is causing the infection to return after antibiotics are done; or 3) have an underlying immune defect (for example, job syndrome). ...Read more

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

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. ...Read more

4 cases of staph infect. This month - besides bug spray, how do I prevent this? No one else in the house gets infected. Been to urgent care every wk!

4 cases of staph infect. This month - besides bug spray, how do I prevent this? No one else in the house gets infected. Been to urgent care every wk!

Colonization: You have a combination of two factors. Nasal carriage of staph aureus and susceptibility to this organism. You can try to eliminate the first by using Mupirocin (bactroban) ointment in your nostrils daily, and washing exclusively with clorhexidine containing soap. The latter creates a thin film on your skin which, if washed off, will no longer kill the staph on your skin. Also, stop scratching. ...Read more

See your doctor: this needs to be checked out by a health care provider. don't squeeze it, or open it. mark the red area with a marker if it is getting bigger or there are streaks of red on the foot or leg, would go in immediately. Yes, if very well could be staph ...Read more

Antibiotic ointment: First, be sure you quit traumatizing your nose, even minor. This is often caused by one's fingernails. Staph and strep pneumonia are normal colonizing bacteria for many people without harm. Harm comes when one's natural body defenses, such intact skin and nose lining is compromised. An antibiotic ointment is helpful as it is very local in effect and potent. ...Read more

 Swollen nasal passages for three months.Nasal swab found large amount of coagulase negative staph. Doctor wants me to take keflex. I was on keflex for 5 years low dose to treat e-coli UTI which is now resistant to keflex.Wont staph be resistant to?

No: A person doesn't get resistent to an antibiotic, but a germ can. If you have not been on keflex in the past months it would likely kill off some of the germs on your body.However; I find coag negative staph to be a normal skin contaminant and not worthy of any treatment.Use of a simple OTC nasal steroid spray like rhinocort would help with most causes of nasal membrane swelling. ...Read more

My daughter has red itchy bumps on her arms and feet. What could be the cause? She was diagnosed with a staph infection but the bumps persist. Bed bugs were mentioned but she is the only person being bitten. Could this be an allergic reaction to something

This : This is tough to answer without a picture. There are several possibilities including bites (fleas or other), eczema or allergic contact dermatitis, lichen planus, folliculitis (staph infection), and others. I doubt bed bugs given the location. I would recommend you try a moisturizer such as cerave cream twice daily and if not better after a few days consider a trip to the dermatologist for diagnosis and treatment options. Bites are common in kids so that is certainly a possibility. If they are bites, avoidance plus a steroid gel might be beneficial. I hope that helps. ...Read more

What causes rid of a staph infection when med's don't work?

Depends on the Med: I would ensure the right medications were used. If you have an abscess, it needs to be drained. Many staph are resistant to antibiotics, but there hasn't been a case of staph with proven resistance to everything. If you mean you keep getting recurrent staph infections, there are certain ways to attempt decolonization of your body of staph. Talk to your doc. ...Read more

Is incision always necessary in case of small pertonsiller abscess due to staph aureus?can't only antibiotics cure it.plz ans both separately

Treatment: If it is truly a peritonsillar abscess, it will most likely need to be drained. It may be possible for antibiotics to treat the disease alone, however not recommended typically. This condition can progress and develop and lead to airway compromise which can be very dangerous. Antibiotics should certainly help, but incision and drainage will most likely be your most effective solution. ...Read more
