摘要: This genus is defined morphologically as gram-positive, partially acid-fast, branching filamentous bacteria that divide by fragmentation. They are strictly aerobic, mycolic acid containing actinomycetes phylogenetically related to Mycobacterium, Corynebacterium, Rhodococcus, Gordona, and Tsukamurella (Wilson et al., 1998). Twelve species comprise this genus; however, the type species, Nocardia asteroides, has been most frequently studied (Beaman, B. L. Beaman, 1994). phenotypically diverse, many investigators believe N. asteroides complex consists of at least 5 6 distinct groups. Some these have now assigned status. Thus, currently includes farcinica, nova. It likely additional will be created from further subdivision taxon. Since routine laboratory identification does not differentiate reports infections due represent total underestimate individual members such farcinica nova (Workman
