For some Gram-negative bacterial infections, antibiotic treatment can cause a more severe reaction than that caused by the base

infection. This is often due to the release of endotoxin from the cell. Endotoxin, or LPS, is harmless in intact pathogens but can cause dangerously low blood pressure and high fever once released.
Which antibiotic here would you recommend against a bacterial pathogen that encodes LPS?

a) polymyxin, because it inserts into the cell membrane, disrupting homeostasis.

b) tetracycline, because it targets bacterial ribosomes.

c) vancomycin, because it disrupts cell wall formation.

d) ethambutol, because it interreupts arabinogalatcan.

Answer:

Polymyxin because, it inserts into the cell membrane and disrupts homeostasis.

Explanation:

Antimicrobial effect reacts with the cell membrane of the gram negative bacteria and causes disruption in their cell membrane by creating pores.

The cell membrane of bacteria release endotoxin for creating defense mechanism.

But the effect of certain antimicrobial peptide disrupt the effect of membrane by releasing electrostatic interaction and creates membrane pores.

The interaction between the microbial peptide and the cell membrane causes disruption of the cell.

Thus polymyxin is used to treat against the gram negative bacteria as they breaks the cell membrane of the bacteria.

Why is it ineffective to treat viral disease with antibiotics? Why is it ineffective to treat viral disease with antibiotics? Pa
Eddi Din [679]

Answer:

Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes

Explanation:

The specificity of the antibiotics to inhibits some  bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition  antibiotics are designed to  have a significant  destructive  effects on  the mechanisms of biochemical reactions in bacteria and its  physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus

What is the term for the layers of bony matrix surrounding the cell at a?
abruzzese [7]
It is probably the l<span>amellae.
The lamellae are sheets of bony matrix. This bony matrix is produced by o</span>steoblasts, which are cells that synthesise collagen<span> and specialised proteins like </span>osteocalcin<span> and </span>osteopontin. These are then the most important constituents of the bony matrix.
