An abbreviated version of CDDEP's weekly digest of public health news, focusing on research in the United States.

The New York Times discusses a recent CDC report, which identifies C. difficile as the leading cause of mortality associated with gastrointestinal infections, and norovirus as the second most common cause.  Patients are at greater risk of contracting C. difficile when seeking medical care and taking antibiotics.

A study in the Proceedings of the National Academy of Sciences explores a bacterial mechanism that disables microcin, a “Trojan horse” antibiotic that, when attached to a peptide, is disguised and taken into bacterial cells as food.

Research in the Medical Journal of Australia suggests that nursing homes could be breeding grounds for resistance.   Surveying four facilities, the study authors find that guidelines for antibiotic prescribing were followed for just over half of upper respiratory and urinary tract infection diagnoses.

The state of Oregon and Pfizer reach a USD 3.34 million settlement over accusations that Pfizer deceptively marketed the antibiotic Zyvox.  The state alleges that Pfizer falsely claimed that Zyvox was superior to a cheaper, generic alternative (vancomycin), and that these claims resulted in excess cost to the health care system and contributed to the rise of antibiotic resistance to a second-line treatment.

Have a sinus infection? New guidelines from the Infectious Diseases Society of America recommend skipping the antibiotics.  The guidelines will be published in the April 15 edition of Clinical Infectious Diseases.

Methicillin-resistant Staphylococcus aureus (MRSA), in combination with the seasonal flu, proves deadly for a family in Maryland.

Scientific American’s Disease Prone blog offers a rundown of the antimicrobial properties of honey.

New research out of Johns Hopkins suggests that “haphazard” hospital infection reporting gives patients little useful information about where to seek care, and consequently, few incentives for hospitals to improve infection control.
