You have not verified your email address. Epub 2007 Jul 31. Many plasmids are designed to include an antibiotic resistance gene, which when expressed, allows only plasmid-containing bacteria to grow in or on media containing that antibiotic. Bacterial resistance to antibiotics poses a great clinical challenge in fighting serious infectious diseases due to complicated resistant mechanisms and time-consuming test methods. Electrochemical aspects of metabolism. Is there any effect that a higher or lower final concentration would have on the growth of bacteria? endAl, gyrA96, thi.

Introduction Bacterial biofilms—sessile microbial communities formed on solid surfaces—are ubiquitous in natural environments as well as those related to medicine and engineering (Elvers and Lappin-Scott 2000). They are usually only set in response to actions made by you which amount to a request for services, such as logging in, using a shopping cart or filling in forms. Beyond its natural resistance to many drugs, its ability to form biofilm, a complex biological system, renders ineffective the clearance by immune defense systems and antibiotherapy.
