HIV co-infection does not affect Mycobacterium tuberculosis mutation rates and does not drive the emergence of antimicrobial resistance within patients in the largest outbreak of multidrug-resistant tuberculosis in Latin America to date.
Ceftriaxone resistance has arisen multiple times in clinical gonococcal populations via previously undescribed RNA polymerase mutations, underscoring the importance of continued surveillance for novel resistance determinants.
A fluoroquinolone resistant variant of Salmonella Typhi has emerged that is likely to be widespread in the Indian subcontinent; therefore fluoroquinolones should not be recommended for empirical typhoid fever therapy in this setting.
Mapping microbial landscapes in indoor environments can predict how contaminants and spoilage resistance genes propagate within food-production environments, yielding novel insight for controlling spoilage.
Shigella flexneri, globally the most frequent cause of bacterial dysentery, is far more diverse, and has caused disease around the world for far longer than other Shigella species by persisting in local environments over extended timescales.
