Mycobacterium goodii

Mycobacterium goodii is an acid-fast bacterial species in the phylum "Actinobacteria" and the genus "Mycobacterium".
Description.
"M. goodii" cells are Gram-positive, nonmotile, acid-fast rods.
Colony characteristics.
Colonies of "M. goodii" are smooth to mucoid, off-white to cream coloured. in After 10–14 days incubation, 78% of all strains produce a yellow or orange pigment.
Physiology.
Strains of "M. goodii" show rapid growth on Middlebrook 7H10 and trypticase soy agar at 30 °C, 35 °C and 45 °C within 2–4 days. They are susceptible to the antibiotics amikacin, ethambutol, and sulfamethoxazole but show intermediate susceptibility to ciprofloxacin, doxycycline and tobramycin and variable susceptibility to cefmetazole, cefoxitin and clarithromycin. They are resistant to isoniazid and rifampicin.
Pathogenesis.
"M. goodii" is found in many of the same settings as "M. smegmatis" and members of the "M. fortuitum" complex. It can cause post-traumatic wound infections especially those following open fractures and with associated osteomyelitis and chronic lipoid pneumonia.
Type strain.
The type strain of "M. goodii" (Strain MO69 = ATCC 700504 = CIP 106349 = DSM 44492 = JCM 12689) was first isolated from a patient with a post-traumatic osteomyelitis of the heel in the United States.
"Mycobacterium goodii" was previously known as "Mycobacterium smegmatis" group 2.
