Beside gram-positive microbes, penicillin can butcher?
Answer:
Fungi
Anerobic bacteria. It is as a result very adjectives for oral/dental infections.
That's it. All penicillin does is interefere with the production of peptidoglycans contained by the cell wall of gram positive bacteria. Gram cynical bacteria also enjoy some peptidoglycans in their scrubby cell wall, but it's not as important to cell function and thus they don't respond.
Spirochetes approaching Treponema Pallidum the cause of Syphilis.
Escherichia coli and Pseudomonas aeruginosa
Gram-positive cocci (except penicillinase-producing staphylococci, penicillin-resistant pneumococci, enterococci, and oxacillin-resistant staphylococci).
Gram-positive rods such as Listeria
Gram-negative cocci such as Neisseria sp (except penicillinase-producing Neisseria gonorrhoeae)
Most anaerobes (with consistent exceptions, such as Bacteroides)
good luck
Penicillin solitary kills gram positive germs. It interferes with pepitoglycan within the bacterial cell wall to stop synthesis. The gram negative cell wall have a lipid coat surrounding it to prevent the action of penicillin, however, some of the other member of the class have better lipid solubility and can penetrate this seam.
