Hello everyone, i already told about E.coli bacteria in my last two previous posts.now i would like to tell about klebsiella which is also a Lactose fermenter(gives pink colour on macconkey agar) like E.coli.
Klebsiella is a capsulated,Gm -ve organism,non motile.it has a peculiar property that it releases "urease" enzyme.
