'''''Mycobacterium lacus''''' is a species of bacteria in the genus ''[[Mycobacterium]]'' known to be a causative agent in immunocompetent individuals.

==Description==
Large, dispersed [[acid-fast]] [[bacilli]] with prominent beading

'''Colony characteristics'''
*Colonies on [[Löwenstein–Jensen medium]] were [[nonchromogenic]], small, with a dry appearance.
*On [[Middlebrook 7H10 Agar|Middlebrook 7H10]] agar, colonies are small, non-pigmented and smooth to rough, with a slightly irregular edge. Younger colonies appeared slightly transparent.

===Physiology===
*Growth was observed on [[Löwenstein–Jensen medium]] at two weeks at both 37 and 42&nbsp;°C and at 3 weeks at 30&nbsp;°C. At four weeks, very little growth was observed at 25&nbsp;°C, and no growth was observed at 52&nbsp;°C.

==Pathogenesis==
*The causative agent of [[bursitis]] in an [[immunocompetent]] individual.

==Type strain==
*Isolated from [[synovial membrane|synovial]] tissue from a 68-year-old female with [[bursitis]] of her right elbow. The likely exposure was in a lake.
Strain NRCM 00-255 = ATCC BAA-323 = DSM 44577
