Why gram positive bacteria typically more resistant that gram negative bacteria to antibiotics that disrupt plasma membranes such as polymyxin B?
Polymixin antibiotics interact with the lipopolysaccharide molecule of Gram negative bacteria. This component forms the outer leaflet of the outer membrane. Gram-positive bacteria do not have an outer membrane or lipopolysaccharide and thus polymixin antibiotics are unable to bind to the cell.
How are perforins different from granzymes?
Perforins are proteins that form pores in the target cell membrane, allowing entry of granzymes into the target cell. Granzymes are enzymes that are delivered into the target cell by perforins and trigger apoptosis, or cell death, in the target cell.
What does a cytotoxic B cell do?
A cytotoxic B cell produces antibodies that can directly bind to and kill infected or abnormal cells. These antibodies mark the target cells for destruction by other immune cells, leading to the elimination of the threat.
What are B cell mechanisms classified as?
B cell mechanisms are classified into two main categories: antibody production and antigen presentation. B cells are primarily responsible for producing antibodies that target specific antigens for removal from the body. Additionally, B cells can present antigens to T cells to initiate a more targeted immune response.

Can you buy neomycin sulfate polymyxin B?

How does Polymyxin B work?
Polymyxin B works by disrupting the bacterial cell membrane, leading to cell death. It binds to the lipid A portion of lipopolysaccharides in the outer membrane of Gram-negative bacteria, destabilizing the membrane structure. This action increases membrane permeability, allowing essential cellular contents to leak out and ultimately resulting in the bacteria's lysis. Polymyxin B is primarily effective against certain Gram-negative bacteria, including Pseudomonas aeruginosa and Escherichia coli.

Does Neomycin or Polymyxin B have penicillin in it?
Polymyxin B does not have penicillin in it, I just called my local pharmacy to ask that question and the answer is no. I should note, however, that the reason I called my pharmacist was because I used a topical ointment that contained Polymyxin B and had a very severe allergic reaction immediately after applying the ointment. I have anaphylaxis to penicillin and thought it may contain penicillin, but the pharmacist tells me it does not. He did advise me to go see my allergist again as I may have developed an allergy to another antibiotic but assured me there is no penicillin in Polymyxin B. Can't help with Neomycin, sorry!
