MYOM2 and infection: Moreover, bacterial cell wall components (e.g., M protein produced by S. pyogenes and mycolic acid produced by M. tuberculosis) and metabolic products of bacteria (e.g., succinic acid or catalase produced by L. monocytogenes) can also contribute to the impairment of phagocytosis or IKB [27, 28] increasing the likelihood of pathogen survival and development of the infection.
