These species form the rapidly growing nonchromogenic
In screening, some lipoproteins were dissociated to water and oxygen by actions of cholesterol esterase/ oxidase and catalase to form a nonchromogenic
product in step 1.
Cultures in liquid and solid media grew a nonchromogenic mycobacterium from sputum and stool samples; results were negative for urine samples.
A bronchoalveolar lavage was performed; samples yielded in culture Pseudomonas aeruginosa and a nonchromogenic mycobacterium.
All isolates yielded smooth to greasy domed nonchromogenic
colonies in culture (online Technical Appendix Figure, wwwnc.cdc.gov/EID/pdfs/11-0888Techapp.pdf).
The colonies were nonchromogenic
, smooth to mucoid, and off-white to cream on Middlebrook 7HI0 and trypticase soy agar.
