		Scotochromogens are slowly growing mycobacteria that form pigment in both light and dark.
		Non-chromogens are those that do not form pigment at all, of which the most important members are those of the MAC complex.

		Carotenogenesis is achieved in the absence of light by scotochromogenic mycobacteria.
		A comparison of the pigmentation of the shielded tube that was exposed once to light with the unshielded tube determines whether the mycobacterium is scotochromogenic, photochromogenic, or nonphotochromogenic on the basis of the criteria as described in Figure 43.

		M scrofulaceum, a scotochromogen, has been isolated from lymph node lesions in pigs, cattle, and certain nonhuman primates.
		These organisms should be differentiated from M gordonae and M flavescens and from other slowly growing scotochromogenic mycobacteria that are common contaminants of water.
		Numerous nonpathogenic, nonphotochromogenic mycobacteria that closely resemble potential pathogens can be isolated from water and soil: M nonchromogenicum, M gastri, M triviale, and M terrae, which closely resemble strains of the M avium complex, may be differentiated by in vitro laboratory examinations.

	a novel Mycobacterium from cervical lymphadenitis
		C.V. Abstract: A slow-growing mycobacterium was isolated from a cervical lymph node of an adolescent male.
		When subcultured on L6wenstein-Jensen medium, the isolate produced smooth, scotochromogenic colonies less than 1 mm in diameter after 6 weeks of incubation at 25'C and 30'C (no growth was observed at 37'C or 43'C).
		Like isolate B76676, Mycobacterium cookii is a scotochromogen that produces detectable growth at 22 °C and 31 °C (but not at 37 °C, 42'C, or 45'C) after 4 weeks.

		M. celatum strains were isolated on currently used liquid media in all reported cases (radiometric Bactec 12B and MB/BacT [Organon Teknika B.V., Boxtel, the Netherlands]), while samples from one of the published case-patients did not grow on conventional Lowenstein-Jensen solid medium, and growth has not been reported for samples from the second case-patient.
		Data from an extended panel of biochemical and cultural tests for conventional identification have not been reported; however, the appearance of a scotochromogenic pale yellow pigment with growth at 45[degrees]C and a negative 3-day arylsulfatase test are in full agreement with our present and previous findings (7).
		All strains showed a partial hybridization with Accuprobe MTB, which disappeared after 10 min of incubation with selection reagent.

		The biochemical profile of this isolate correlated well with published data for M. neoaurum, a rapid-growing scotochromogenic mycobacterium species.
		The patient was treated with oral ciprofloxacin and doxycycline and her graft was removed due to coincident complications.
