Natural products have been a rich source of compounds for drug discovery. However, their
use has diminished in the past two decades, in part because of technical barriers to …

Pseudomonas fluorescens is not generally considered a bacterial pathogen in humans;
however, multiple culture-based and culture-independent studies have identified it at low …

The vast majority of microorganisms live and grow in aggregated forms such as biofilms and
flocs (“planktonic biofilms”). This mode of existence is lumped in the somewhat inexact but …

Various gram-negative animal and plant pathogens use a novel, sec-independent protein
secretion system as a basic virulence mechanism. It is becoming increasingly clear that …

cagA, a gene that codes for an immunodominant antigen, is present only in Helicobacter
pylori strains that are associated with severe forms of gastroduodenal disease (type I …

▪ Abstract Bacteria produce and secrete lipases, which can catalyze both the hydrolysis and
the synthesis of long-chain acylglycerols. These reactions usually proceed with high …

Bacterial pathogens employ a number of genetic strategies to cause infection and,
occasionally, disease in their hosts. Many of these virulence factors and their regulatory …

While many textbooks are available for introducing microbiology at the college level, and
collections reviewing the latest research in specifıc organisms or environments are …

Pseudomonas aeruginosa is an opportunistic pathogen, mainly affecting severe patients,
such as those in intensive care units (ICUs). High levels of antibiotic resistance and a long …

▪ Abstract ATP-binding cassette (ABC) transporters couple ATP hydrolysis to the uptake and
efflux of solutes across the cell membrane in bacteria and eukaryotic cells. In bacteria, these …
