Mycobacterium phlei
Encyclopedia
Mycobacterium phlei is an acid-fast
bacteria
of the genus Mycobacterium
. They are named this way because they contain mycolic acid
s, which is also the reason that simple staining or Gram staining does not give good results with this microbe. In fact, they cover their cell bodies with mycolic acid
, which makes them one of the hardest genus of bacteria to kill.
Of the genus Mycobacterium, M. phlei, is characterized as one of the fast-growing mycobacteria. On egg media and sheep's blood agar, the colonies are flat with a distinctive pigmentation ranging from deep yellow to orange.
M. phlei has only occasionally been isolated in human infections, and patients infected with M. phlei generally respond well to anti-mycobacterial therapy.
M. phlei, has been known to have up to 73% GC content, also making its Tm very high
Acid-fast
Acid-fastness is a physical property of certain bacteria, specifically their resistance to decolorization by acids during staining procedures.Acid-fast organisms are difficult to characterize using standard microbiological techniques Acid-fastness is a physical property of certain bacteria,...
