Defining bacterial species in the genomic era : insights from the genus Acinetobacter [PDF]

, 2012
Background: Microbial taxonomy remains a conservative discipline, relying on phenotypic information derived from growth in pure culture and techniques that are time-consuming and difficult to standardize, particularly when compared to the ease of modern

Differing Prevalence and Diversity of Bacterial Species in Fetal Membranes from Very Preterm and Term Labor [PDF]

, 2009
Background: Intrauterine infection may play a role in preterm delivery due to spontaneous preterm labor (PTL) and preterm prolonged rupture of membranes (PPROM). Because bacteria previously associated with preterm delivery are often difficult to culture,

DNA vaccines for bacterial infections

Immunology & Cell Biology, 1997
DNA vaccines are an exciting development in vaccine technology which may have a special role in preventing viral infections and as ‘theracines’ for cancer. Their use in preventing bacterial infections has, by comparison, been less well documented.

Hot-spot consensus of fluoroquinolone-mediated DNA cleavage by gram-negative and gram-positive type II DNA topoisomerases [PDF]

, 2007
Bacterial DNA gyrase and topoisomerase IV are selective targets of fluoroquinolones. Topoisomerase IV versus gyrase and Gram-positive versus Gram-negative behavior was studied based on the different recognition of DNA sequences by topoisomerase ...
