Gram positive vs gram negative teichoic acid
WebGram-negative bacteria have an outer membrane, are more resistant to antibiotics, and produce endotoxins and exotoxins that can cause foodborne illness. Meanwhile, gram-positive bacteria have a thick layer of peptidoglycan and teichoic acid, produce enterotoxins and neurotoxins, and are susceptible to some antibiotics.
