WebThis episode features a conversation with Dr. Andrea Prinzi and Dr. Rodney Rohde. They talk about an article titled "The Role of Bacterial Biofilms in Antimicrobial Resistance" What are biofilms? What organisms are seen in them? What role do they play in antimicrobial resistance (AMR)? Tune in to find out. WebJun 12, 2024 · Microscopic, electrochemical and surface characterization techniques were used to investigate the effects of iron reducing bacteria (IRB) biofilm on carbon steel corrosion for 72 and 168 h under batch conditions. The organic nutrient availability for the bacteria was varied to evaluate biofilms formed under nutritionally rich, as compared to …

WebBacterial biofilm formation is a complex process and can be described in five main phases: (i) reversible attachment phase, where bacteria non-specifically attach to surfaces; (ii) irreversible attachment phase, which involves interaction between bacterial cells and a surface using bacterial adhesins such as fimbriae and lipopolysaccharide (LPS); … on the hunt dog food
Microbial iron respiration: impacts on corrosion processes
WebMar 8, 2024 · Iron is a major nutrient required for bacterial growth yet its availability in the host is dramatically reduced since most iron is bound to proteins such as transferrin and hemoglobin. To circumvent iron scarcity, several pathogens rely on the production of … WebSep 1, 2024 · Iron scavenging has been proposed as a viable target, because bacterial and fungal pathogens must overcome the nutritional immunity of the host to be virulent. This … WebCampylobacter is a leading foodborne pathogen worldwide. Biofilm formation is an important survival mechanism that sustains the viability of Campylobacter under harsh stress conditions. Iron affects biofilm formation in some other bacteria; however, the effect of iron on biofilm formation has not been investigated in Campylobacter. In this study, we … on the human body proximal means
