How sublethal levels of antibiotics and heavy metals select for clinically important multidrug resistance plasmids is largely unknown. Carriage of plasmids generally confers substantial fitness costs, implying that for the plasmid-carrying bacteria to be maintained in the population, the plasmid cost needs to be balanced by a selective pressure conferred by, for example, antibiotics or heavy me...

BACKGROUND AND OBJECTIVES Heavy metals are considered as high risk biocides due to their harmful effects on human health, the environment and other living organisms. Bacterial strains showing resistance to heavy metals has been used for removing such toxic materials from the environment. In this study we isolated and characterized a heavy metals-resistance halophilic bacterial strains from Kal ...

This paper focuses on the general ways in which microbes interact with metals. Some bacteria have evolved mechanisms to detoxify heavy metals, and some even use them for respiration. Microbial interactions with metals may have several implications for the environment. Microbes may play a large role in the biogeochemical cycling of toxic heavy metals also in cleaning up or remediating metal-cont...

Recreational waters should be considered as risks for Enterococcal infections in regions with high utilization and long exposure periods. The aim of this study was to investigate the resistance of Enterococci to selected antibiotics and some heavy metals [Pb+2, Fe+2, Zn+2 and Cr+2]. A total of 75 Enterococcal isolates was obtained from 54 bathing and ...

BACKGROUND Antibiotic resistance (ABR) is one of the major health emergencies for global society. Little is known about the ABR of environmental bacteria and therefore it is important to understand ABR reservoirs in the environment and their potential impact on health. METHOD/DESIGN Quantitative and qualitative data will be collected during a 3-year follow-up study of a river associated with ...

In recent years, heavy metal pollution has become one of the most serious environmental problems. The pollution of environment with toxic heavy metals is spreading throughout the world along with industrial progress. Presence of heavy metals even in traces is toxic and detrimental to all living organisms. Moreover it cannot be degraded in to simpler harmless compounds like other pollutants incl...

In this study, it was aimed to determine of heavy metal resistance of bacterial isolates from coastal city sediment (Izmir Bay). Thirty isolates (Bacillus, Marinibacillus, Halobacillus) were identified by phylogenetic analysis and these strains were investigated in respect of the MICs of heavy metals (Hg, Cu, Cd, Cr, Ni and Pb). The MICs of heavy metals were different for each strain but the ge...
