Scientists in bars, egoistic lot getting sozzled (15)

I believe the answer is:

bacteriologists

'scientists' is the definition.
(bacteriologist is a kind of scientist)

'bars egoistic lot getting sozzled' is the wordplay.
'getting sozzled' indicates an anagram (sozzled can mean drunk and therefore disordered).
'bars'+'egoistic'+'lot'='barsegoisticlot'
'barsegoisticlot' is an anagram of 'BACTERIOLOGISTS'.

'in' acts as a link.

(Another definition for bacteriologists that I've seen is " Scientists".)

I've seen this clue in The Telegraph.
