Select the statement that applies to Mycoplasmas.

		These bacteria are intrinsically resistant to β-lactam antibiotics.
		These bacteria have mycolic acids in their cell wall.
		These organisms have a rapid generation time.
		Mycoplasmas resist the effects of β-lactam drugs by synthesizing a β-lactamase.
		These organisms all contain a terminal organelle.

Expert Solution

Answer :- These bacteria are intrinsically resistant to beta lactum antibiotics.

Explanation :- Mycoplasmas are the smallest and simplest self producing Gram negative bacteria. Mycoplasmas lack cell wall around their cell membrane. Mycoplasmas are pleomorphic i.e they vary in shape and mostly non motile. General metabolic nature is chemoorganoheterotrophic and require cholesterol for growth. They can be saprophytes or parasites and usually facultative anaerobes.

Absence of cell wall around the cell membrane make Mycoplasmas intrinsically beta lactum antibiotics resistant it, dont need any external factor or substance to be antibiotic resistance.

So from the above discussion we can conclude that the answer is option "a" .

Research has uncovered how bacteria which are antibiotic resistant protect bacteria which are not. For example, in an infected wound, an antibiotic resistant Gp A Strep will secrete the bacterial enzyme beta-lactamase. This enzyme will cut apart the beta-lactam ring on penicillins and cephalosporins. It destroys those antibiotics. Any other bacterial species in the wound, even those sensitive to penicillins and cephalosporins, are protected as well. How could you prove that the growth you saw in the mixed section of...
