Morphology and structure of bacterial cells under transmission electron microscopy (80000x-100000x).

(A) Morphology; (B) length; (C) diameter, and (D) thick peptidoglycan cell wall. Each value is expressed as the mean ± SEM of three independent experiments (n = 3). Different letters are significantly different (P < 0.05), by applying ANOVA and Tukey test. Scale bar: 200nm.
