1. A 28-year-old female with folliculitis is not responsive to a 10-day treatment course with penicillin. An enzyme produced by the etiologic agent is most likely responsible for this treatment failure. At which site on the molecule shown does this enzyme act to destroy penicillin? The structural integrity of the β-lactam ring in penicillins is essential for their antimicrobial activity. Many resistant strains of staphylococci produce a β-lactamase (penicillinase) that cleaves the β-lactam ...

MICR221 Exam Questions With Correct Answers. Describe the process of binary fission - answer1. Genetic material replicates itself while the cell elongates 2. Genetic material migrates to either end of the cell and the septum begins to form 3. Septum then completely forms and the cell begins to separate 4. Two identical daughter cells are formed How does population growth occur? - answerOccurs through binary fission, cell number increases exponentially Define the mean generation time - a...
