an infection caused by bacteria.
*Antibiotics target microorganisms such as
bacteria, fungi and parasites.
*They are not effective against viruses.
TYPES OF ANTIBIOTICS:
The commonly used antibiotic types are:
2. AMINOGLYCOSIDES: AMINOGLYCOSIDES ARE
EFFECTIVE IN INHIBITING PROTEIN PRODUCTION IN
BACTERIAL CELLS BY BINDING WITH RIBOSOMES THAT
This antibiotic includes gentamicin, streptomycin and
Macrolides just like the other types of antibiotics it
interfere with the protein formation of bacteria by
binding with bacterial ribosomes.
This is the latest class of antibiotics
comprises ciprofloxacin, enoxacin,
levofloxacin, norfloxacin, ofloxacin,
gatifloxacin.These antibiotics are mostly used
to treat urinary tract infections.
MODE OF ACTION:
Quinolones inhibit bacterial growth by
blocking DNA replication.DNA is the
genetic material of the cells, and is
responsible for proper functioning of
ANTIBIOTICS ARE PROTEIN SYNTHESIS INHIBITOR,
THEY BIND WITH 30S RIBOSOMAL SUBUNIT.
TETRACYCLINE ANTIBIOTICS ARE: TETRACYCLIN,
USE: respiratory tract infection, eye infections,
sinuses, urinary tract, skin infection. Tetracyclines also
are used to treat severe acne.
