Streptogramin Resistance in Humans Linked to Poultry Exposure
A streptogramin used to promote growth in poultry is also used to treat E. faecium infections in humans. Researchers believe that consumption of treated poultry may be causing resistance to the antibiotic in humans.

Impact of CA-MRSA on MRSA Antimicrobial Susceptibility in Hospitals
Compared to traditional hospital-associated MRSA (H-MRSA), CA-MRSA strains appear to be susceptible to a variety of antibiotics including fluoroquinolones but develop resistance once introduced to a hospital setting.

Inter-Hospital Transfers May Contribute to the Spread of MRSA Between Nurseries
Area nurseries are considered to be a reservoir of MRSA and the high rate of inter-hospital baby transfers is believed to facilitate the spread of MRSA. These concerns are sparking changes in policy regarding admission of MRSA activity and communication among hospitals.

Patients Infected with MRSA Upon Discharge May Contribute to the Spread of Community Acquired MRSA
Decolonization of patients with H-MRSA following discharge from the hospital is effective at preventing the spread of MRSA in the community given appropriate contact and follow-up with the patient.

New Drugs to Treat TB
For the first time in almost 40 years several new drug classes are in clinical trials for the treatment of tuberculosis. Researchers are hopeful these new drugs will shorten the duration of therapy and provide for a highly active and improved therapy of the currently multidrug-resistant TB.

Looking to the Soil for New Antibiotic Resistance Mechanisms
Streptomycetes, which evolve in soil ecosystems and synthesize over 50 percent of antibiotics in clinical use, may serve as valuable reservoirs of future antibiotic-resistance mechanisms. Identifying these mechanisms in the environment may serve as an early warning for future resistance in pathogenic bacteria, giving researchers more time to develop new compounds to overcome new forms of resistance.
