Quorum sensing (QS) is a cell density-dependent communication mechanism between bacteria through small signaling molecules. When the number of QS signaling molecules reaches a threshold, they are transported back into...
Acinetobacter is an important opportunistic, multidrug resistant pathogen causing majority of nosocomial infections worldwide. The multidrug resistance is attributed by a plethora of efflux pumps and the overexpression of the...
A number of bacterial species coexist in oral cavities as a biofilm rather than a planktonic arrangement. By forming an oral biofilm with quorum sensing properties, microorganisms can develop a...
Infections with Pseudomonas aeruginosa are difficult to treat not only because it is often associated with multidrug-resistant infections but also it is able to form biofilm. The aim of this...
Pseudomonas aeruginosa, as an opportunistic pathogen, establishes a chronic infection in the respiratory track of patients suffering from pneumonia and bronchiectasis, including cystic fibrosis. Biofilm formation inside the oversecreted mucus...
Vibrio vulnificus, a gram-negative halophilic marine bacterium and opportunistic pathogen, must withstand various environmental changes, especially the simultaneous change of temperature and salinity (SCTS) from 25degrees C/2.5% to 37degrees C/0.9%...
Purpose: Catheter associated urinary tract infection (CAUTI) frequently occurs in the patients with an indwelling Foley catheter, and it can cause serious morbidity or mortality. However, there have been no...
BACKGROUND: Recent data suggests the inoculum effect of methicillin-susceptible Staphylococcus aureus (MSSA) against beta-lactam antibiotics and their association with functionality or genotypic variation of agr locus.
METHODS: MSSA blood isolates were...
