G. Aminoglycosides

The aminoglycoside/aminocycitol antibiotics are compounds with a broad
spectrum of activity against many bacterial species although chemical use in
most cases is limited to gram-negative bacterial infections.

 Neomycin  Gentamicin
 Streptomycin/Dihydrostr  Kanamycin
eptomycin  Amikacin

H. Spectinomycin

Spectinomycin is an aminocyclitol antibiotic, but its structure differs from
that of the aminoglycosides.

I. Macrolides

The macrolides are a large group of structurally related antibiotics but only a
few have been found to be clinically useful. The macrolides' spectrum of
activity is essentially against gram-positive organisms. Some strains of
gram-negative bacteria as a well as Mycoplasma, Chlamydia, Rickettsia, and
Actinomycetes may be susceptible.

 Erythromycin  Tilmicosin phosphate
 Tylosin  Pirlimycin

J. Lincosamides

Lincomycin has been employed in swine and cattle for systemic infections.
This antibiotic is primarily bacteriostatic and possesses an antimicrobial
spectrum that includes only gram-positive organisms, several anaerobes and
some Mycoplasma species.

 Lincomycin
 Clindamycin
