You find a rotting whale on the beach. You smell that distinctive smell of death. That death smell is from chemicals produced by the bacteria that are decomposing this whale. We produced these chemicals in lab this semester. What are these smelly chemicals and why are the bacteria producing

Which of the following does NOT describe a mechanism of antibiotic resistance among bacteria? enzymes to hydrolyze or chemically alter the antibiotics mutations in target molecules so that antibiotics can no longer bind efflux pumps cell wall diffusion barrier, e.g. Gram-negative outer membrane, Acid Fast cell wall of Mycobacterium O increased synthesis of porins to increase antibiotic diffusion across membranes

how to find unknown bacteria

The majority of antibiotics used in the clinic aremade as natural products by bacteria. Why do you supposebacteria make the very agents we use to kill them?

In 1864, Lister observed that patients recovered completely from simple fractures but that compound fractures had “disastrous consequences.” He knew that the application of phenol (carbolic acid) to fields in the town of Carlisle prevented cattle disease. Lister treated compound fractures with phenol, and his patients recovered without complications. How was Lister influenced by Pasteur’s work? Why was Koch’s work still needed?

Polymyxins are antibiotics that are used in the treatment of Gram-negative bacterial infections. You are given samples of two different types of bacteria. You are told that Bacteria A is Gram-negative bacteria and Bacteria B is Gram-positive bacteria. Describe, in your own words, how you would confirm the bacterial types.
