Mycobacterium shottsii is a species of slow growing, rod-shaped bacterium from the family Mycobacteriaceae. The species was first isolated from striped bass (Morone saxatilis).
Taxonomy Mycobacterium shottsii was first isolated from striped bass with granulomatous disease in Chesapeake Bay. M. shottsii was validly described as a novel species of Mycobacterium in 2003 on the basis of 16S rRNA, growth, and phenotypic characteristics. The species was named after the American fish bacteriologist Emmett Shotts.
Description Mycobacterium shottsii grows on Middlebrook 7H10 agar. Due to its slow growth rate, colonies take 4 to 6 weeks to become visible. The species has an optimum growth temperature of 23 °C and is unable to grow at 37 °C.
M. shottsii is urease and niacin positive.
