Antibiotic Resistance Patterns in Invasive Group B Streptococcal Isolates (2009)

Mei L. Castor, Cynthia G. Whitney, Kathryn Como-Sabetti, Richard R. Facklam, Patricia Ferrieri, Joanne M. Bartkus, ...

Antibiotics are used for both group B streptococcal (GBS) prevention and treatment. Active population-based surveillance for invasive GBS disease was conducted in four states during...

Limiting the Spread of Resistant Pneumococci: Biological and Epidemiologic Evidence for the Effectiveness of Alternative Interventions

Schrag, Stephanie J., Beall, Bernard, Dowell, Scott F.

Streptococcus pneumoniae infections are a leading cause of respiratory illness in young children, the elderly, and persons with chronic medical conditions. The emergence of multidrug-resistant...

Spontaneous Mutation Rate of Measles Virus: Direct Estimation Based on Mutations Conferring Monoclonal Antibody Resistance

Schrag, Stephanie J., Rota, Paul A., Bellini, William J.

High mutation rates typical of RNA viruses often generate a unique viral population structure consisting of a large number of genetic microvariants. In the case of viral pathogens, this can result in...

Emergence of Streptococcus pneumoniae with Very-High-Level Resistance to Penicillin

Schrag, Stephanie J., McGee, Lesley, Whitney, Cynthia G., Beall, Bernard, Craig, Allen S., Choate, Miriam E., ...

Penicillin resistance threatens the treatment of pneumococcal infections. We used sentinel hospital surveillance (1978 to 2001) and population-based surveillance (1995 to 2001) in seven states in the...

Sentinel Surveillance: A Reliable Way To Track Antibiotic Resistance in Communities?

Schrag, Stephanie J., Zell, Elizabeth R., Schuchat, Anne, Whitney, Cynthia G.

We used population-based data to evaluate how often groups of randomly selected clinical laboratories accurately estimated the prevalence of resistant pneumococci and captured trends in resistance...
