Efflux pumps are what microbes use to rid themselves of toxic materials and drugs. The way science is perusing this is to attach these pumps with compounds called efflux-pump inhibitors. These compounds have no infection fighting power but can make current antimicrobial drugs more effective (Christensen). Microbes that caused sickness in the pre anti...

Flagella And Cilia Planar Waves Movement
394 wordsFlagella Flagella are necessary for the active movement of bacterial cells and protozoa. Flagella are single, whip-like structures that propel an organism through an aquatic environment. They use undulatory motions, where the waves of motion start at the base of the flagellum. The size, the volume of the medium, the length, position and width of the flagella on the organism determine the direction and speed propulsion of the cell. There are three different types of flagella movement. They are ei...
