Introduction: The type IV Pilin is an important colonization factor for opportunistic pathogens of Pseudomonas aeruginosa, which plays a role in the formation of biofilms and binding to the host cells. Each type of Pilin is coded with a particular auxiliary gene. This specific relationship can be used as a therapeutic target for detecting Pseudomonas aeruginosa strains as well as its molecular ...
Introduction: Pseudomonas aeruginosa is one of the most important bacteria causing nosocomial infections, especially in immunocompromised patients. Many antibiotics such as aminoglycosides, quinolones, and beta-lactams are used to treat infections caused by this bacterium. But the emergence of hospital resistance and outbreaks of resistance strains have been widely reported. The aim of this stu...
The perception and response to cellular death is an important aspect of multicellular eukaryotic life. For example, damage-associated molecular patterns activate an inflammatory cascade that leads to removal of cellular debris and promotion of healing. We demonstrate that lysis of Pseudomonas aeruginosa cells triggers a program in the remaining population that confers fitness in interspecies co...
Laccases (benzenediol: oxygen oxidoreductases, EC 1.10.3.2) are multicopper blue oxidases that are widely distributed in higher plants, some insects, fungi and bacteria [1]. Microbial enzymes continue to draw greater attention as alternative to chemical processes which would enable the industries to meet the increasingly stringent environment requirements to reduce the pollution load. The highl...
Pseudomonas aeruginosa is an opportunistic pathogen which uses a number of strategies to cross epithelial and endothelial barriers at cell-cell junctions. In this review, we describe how the coordinated actions of P. aeruginosa's virulence factors trigger various molecular mechanisms to disarm the junctional gate responsible for tissue integrity.
Objective: To investigate infection distribution of Pseudomonas aeruginosa on burned patients in our hospital as well as its drug resistance in order to provide reference of clinical use of antibiotics. Methods: Statistically analysed 481 Pseudomonas aeruginosa and their drug sensitive test results from burned patients who were sent to hospital from January 2004 to December 2006. Results: In ou...
Background: DNA immunization is an appropriate method to produce an immunological response. Pseudomonas aeruginosa produces exotoxin A which is highly cytotoxic for eukaryotic cells. Since domains II (translocation domain) and 1b of the toxin have antigenic qualities, so they could be useful candidates to protect against pseudomonas infections. Objectives: To evaluate if recombinant plasmid co...
Background & Aims: One of the main causes of nosocomial infection is pseudomonas aeruginosa and carbapenems is one of the most important classes of antibiotics used in the treatment of infections caused by this bacteria. Metallo-beta-lactamase (MBL) production is one of the most important mechanisms of resistance to carbapenems and their increased prevalence is a serious threat to treatment of ...
BACKGROUND Nowadays, due to increased public awareness about water pollution and water borne diseases as well as water network deficiencies, bottled water consumers have increased dramatically worldwide, including Iran. Pseudomonas aeruginosa is an opportunistic human pathogen capable of causing widespread infections in burn and immune-compromised patients. The aim of this study was to investig...
Background and Objective: Pseudomonas aeruginosa is an opportunistic nosocomial pathogen. Evidence suggests that the incidence of enzyme-producing strains of Pseudomonas aeruginosa Metalo Beta Lactamases (MBL) is a major problem in the treatment of infections caused by this organism. The aim of this study was to investigate the frequency of class I and II integrons among metalobetalactamase pro...
