Jul 01, 2012 · Nocardia brasiliensis is an intracellular microorganism and the most common etiologic agent of actinomycetoma in the Americas. Several intracellular pathogens induce an immunosuppressive microenvironment through increases in CD4+ Foxp3+ regulatory T cells (Treg), thus downregulating other T-cell subpopulations and assuring survival in the host. Nocardia cyriacigeorgica, N. farcinica, and N. nova were separated from the Nocardia asteroides complex and Nocardia pseudobrasiliensis from Nocardia brasiliensis. These species were validated primarily on the basis of DNA-DNA hybridization, 16S rRNA gene sequence analysis, antimicrobial susceptibility and biochemical profiles, and, to a lesser

Nocardia - an overview | ScienceDirect Topics Nocardia asteroides complex are thought to be the most common cause of nocardiosis and includes many species of varying susceptibility including Nocardia abscessus which has been shown to cause pulmonary and brain infections, Nocardia nova and Nocardia farcinica. Nocardia brasiliensis causes mycetoma including cellulitis and abscesses. Nocardiosis - PubMed Central (PMC) Members of the genus Nocardia are associated with the group of microorganisms known as the aerobic actinomycetes and belong specifically to the family Mycobacteriaceae.The nocardiae contain tuberculostearic acids but differ from the mycobacteria by possession of shorter-chained (40- to 60-carbon) mycolic acids.
