Q78: Which one of the following is not true of mycoplasmas? - General Agriculture, Cell Biology, Genetics, Biochemistry & Plant Protection - ICAR AIEEA PG 2024 - Plant Biotechnology | Agrigyan

Mycoplasmas (class Mollicutes) are the smallest known self-replicating organisms. Key features include the absolute lack of a peptidoglycan cell wall and resistance to beta-lactam antibiotics. Crucially, most Mycoplasma species are not obligate intracellular parasites and can indeed be readily cultured in vitro in specialized cell-free artificial media enriched with serum/sterols, producing characteristic 'fried-egg' morphology colonies. Therefore, stating that 'they cannot be cultured in laboratory' is false.
