Abstract:
Pseudomonas aeruginosa is a pathogenic bacterium that can contaminate water. In this study, 430 water samples were evaluated for P. aeruginosa, antibiotic resistance, and the abundance of virulence factors. P. aeruginosa was isolated from 28 (6.51%) water samples. Among the types of water, well and spring water showed the highest P. aeruginosa with, respectively, 20 (15.6%) and 5 (8.06%) positive samples per type of samples. Drinking water and mineral water showed minor contamination with P. aeruginosa. The prevalence of antibiotic resistance against meropenem, imipenem, erythromycin, gentamic

Introduction: In recent decades, Russia, like the rest of the world, has seen a rapid increase in antimicrobial resistance (AMR) among pathogens causing infectious diseases. The development of drug resistance leads to microorganisms' ability to survive despite the use of etiotropic therapy. Alongside multidrug resistance (MDR), hypervirulence – associated with the acquisition of additional genetic material and the emergence of new genetic lineages – is becoming increasingly significant.

Based on their activity, Pseudomonas biocontrol strains come in three types.

Abstract Cathodic protection (CP) is known as a reliable method to protect steel from corrosion. However, the influence of CP on biofilm formation and maturation is not well known. There are three possible effects of CP on biofilm formation and maturation. Those are: 1) deprivation of anchorage sites for bacterial adhesion, 2) increase of electrostatic repulsion between the steel surface and negatively charged bacteria, 3) elimination of bacteria in the biofilm by increasing pH. To investigate these possible effects of CP on biofilm, carbon steel coupons were immersed in artificial seawater wi

To mitigate this risk, prophylactic antimicrobials are often required, further exacerbating the proliferation of antibiotic resistance.
