Nocardia is a genus of bacteria with more than 100 species.[3] It is found worldwide in organic-matter-rich soil.[4]

Some species cause harm if eaten.[5]

Culture

Nocardia uses aerobic respiration to grow in a wide temperature range.[6]

Virulence

Most Nocardia strains have a virulence factor which damages hosts. Transmission of bacteria via inhalation or through open wounds may lead to Nocardia infection. People with weakened immune systems are more susceptible to Nocardia infections.[7]

Treatment

Nocardia infections are treated by sulfonamide antibiotics.[8] Antibiotic therapy and proper wound care are essential to patient recovery.
