Cefaclor is active against many bacteria, including both Gram-negative and Gram-positive organisms.

Gram-positive organisms are able to retain the crystal violet stain because of the high amount of peptidoglycan in the cell wall.

Most pathogens in humans are Gram-positive organisms.

It has antibiotic activity against a wide range of Gram-negative and Gram-positive organisms.

The peptidoglycan layer is important for cell wall structural integrity, especially in Gram-positive organisms, being the outermost and primary component of the wall.

Daptomycin is a lipopeptide antibiotic used in the treatment of systemic and life-threatening infections caused by Gram-positive organisms.

It is efficient against Gram-positive organisms.

They act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls, which is especially important in Gram-positive organisms.

Acaricomes phytoseiuli is a Gram-positive, aerobic, non-motile and non-spore-forming organism.

It produces di-2,4-diacetylfluoroglucylmethan, which is antibiotically active against Gram-positive organisms.
