nocardia farcinica nocardia farcinica nocardia farcinica is a species of bacteria, once thought to be associated with farcy, and a member of the genus nocardia. this species is very similar in phenotype to nocardia asteroides, to the degree that some isolates of n. asteroides were later found to be nocardia farcinica. nocardia farcinica scientific classification domain: bacteria phylum: actinomycetota class: actinomycetia order: mycobacteriales family: nocardiaceae genus: nocardia species: n. farcinica binomial name nocardia farcinicatrevisan 1889 (approved lists 1980) type strain atcc 3318ccug 10109ccug 27778ccug 48656cip 104775dsm 43257dsm 43578dsm 43665iegm 621ifo 15532jcm 3088m. goodfellow n898/atcc 3318nbrc 15532nctc 11134nrrl b-2089 synonyms "nocardia blackwellii" (erikson 1935) waksman and henrici 1948 pathogenicity n. farcinica may be a causative agent of nocardiosis or of secondary infections in immunocompromised patients. strains of this species have been isolated from human brain abscesses. genome n. farcinica contains a 6 million base pair genome with an average gc content of 70.8%. a sequenced strain, ifm 10152, is also known to contain two plasmids, pnf1 pnf2. the chromosome encodes 5,674 potential protein-coding open reading frames. this genome may have undergone numerous gene duplication events as a result of adapting to new environments.
