The lack of a protective cell wall may make mycoplasmas more sensitive to drying, heat, and some biocides. Other bacteria (as discussed below) that normally have a cell wall can also be present in a cell wall-free form and are referred to as L or cell wall-deﬁcient forms. 5 Simple representation of a mycoplasma cell surface structure. defense mechanisms. Examples of described cell wall-deﬁcient forms of bacteria are Helicobacter, Mycobacterium, Pseudomonas, and Brucella.
