Determining whether a staph infection can be effectively treated with common antibiotics such as methicillin, penicillin and amoxicillin may soon get a little quicker. The FDA has just cleared a new test that can rapidly assess whether the infection-causing bacteria are methicillin-resistant. Current lab methods take one to two days for a result, according to the new test's manufacturer . The FDA says the new test, which uses a sample of the patient's blood, can determine whether the infection is caused by methicillin-resistant Staphylococcus aureus (commonly known as MRSA)

Hey, hand sanitizers. You can only do so much – and preventing MRSA infection isn’t one of those things -- so stop over-promising! That was the gist of warning letters from the Food and Drug Administration to four makers of the popular products. Apparently, the manufacturers of Staphaseptic, Safe4Hours, Dr. Tichenor’s and CleanWell products had suggested that various gels, protectants and what-not could protect against infection with methicillin-resistant Staphylococcus aureus bacteria.

MRSA, the potentially deadly bacteria more formally known as methicillin-resistant Staphylococcus aureus, has grabbed quite a few headlines this week. Canadian researchers found MRSA (and VRE, other drug-resistant bacteria) in bedbugs in Vancouver; and American researchers found MRSA and other staph bacteria on a few samples of supermarket meat in Detroit. The superbug news comes a month after researchers from a nonprofit biomedical research center found that about half of the grocery store meat they sampled was contaminated with staph bacteria , about half of which were resistant to at least three classes of antibiotics.

Bedbugs leave their victims with itchy red welts, but they haven’t been considered much of a threat when it comes to the spread of disease. A new report calls that assumption into question. Researchers have now found antibiotic-resistant bacteria in bedbugs from three hospital patients in Vancouver, Canada. On one patient, researchers found three bedbugs carrying methicillin-resistant Staphylococcus aureus , or MRSA, a bacterium resistant to many common antibiotics. On two patients, they found a bedbug with vancomycin-resistant Enterococcus faecium , or VRE, another bacterium resistant to common antibiotics. The report was published online before being printed in the CDC journal Emerging Infectious Diseases . The researchers hasten to point out that there is no, repeat, no evidence linking bedbugs to disease transmission.

Last month, public health researchers reported that six Canadians -- one in Ontario, five in Saskatchewan -- were infected with methicillin-resistant Staphylococcus aureus, or MRSA, drug-resistant staph. That may not sound unusual, but there was something odd about their illnesses: They were caused by a strain that during the last few years has spread through livestock and farm workers in Europe and North America. But the Canadians made sick by the bacterium had no contact with animals or farming; one of them, an elderly woman, had been housebound for several years.

When an HIV-infected patient walked into Dr. Daniel Berger's office with a nasty sore on his wrist, the physician suspected the culprit was a bacterium known as MRSA. The test results, however, were unexpected. Yes, this was methicillin-resistant Staphylococcus aureus, but it was unresponsive to two medications that are recommended, mainstay treatments. Berger realized the already-formidable microbe had strengthened its defenses. "I was quite concerned, needless to say," said Berger, who since that incident two years ago has treated several other patients with similar infections.
