TY - CHAP M1 - Book, Section TI - Actinomyces and Nocardia A1 - Ryan, Kenneth J. PY - 2022 T2 - Sherris & Ryan's Medical Microbiology, 8th Edition AB - Actinomyces and Nocardia are Gram-positive rods characterized by filamentous, tree-like branching growth, which has caused them to be confused with fungi in the past. They are opportunists that can sometimes produce indolent, slowly progressive diseases. A related genus, Streptomyces, is of medical importance as a producer of many antibiotics, but it rarely causes infections. Important differential features of these groups and of the mycobacteria to which they are related are shown in Table 28–1.
