Nocardia farcinica

Nocardia farcinica
Scientific classification
Kingdom: Bacteria
Phylum: Actinobacteria
Order: Actinomycetales
Suborder: Corynebacterineae
Family: Nocardiaceae
Genus: Nocardia
Species: Nocardia farcinica

Nocardia farcinica is a species of bacteria 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.[1]

Pathogenicity

N. farcinica may be a causative agent of nocardiosis[2] or of secondary infections in immunocompromised patients.[3] Strains of this species have been isolated from human brain abscesses.[4]

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.[5]
