Vegetative and aerial mycelium. tive bacteria, gram-negative cocci, anaerobic bacteria, spirochaetes, and ac-tinomycetes; streptomycin is active against a variety of gram-negative and acid-fast bacteria, as well as upon gram-positive organisms which have be-come resistant to penicillin. Mycoplasmas are considered to be one of the simplest and smallest bacteria. The absence of a rigid cell wall makes them resistant to antibiotics and antibacterial drugs like penicillin and streptomycin. Mycoplasma can pass through filtration methods because of its ability to change shape and the absence of a rigid cell wall.Penicillin was discovered in London in September of 1928.
