Surgery – MCQ 98 – Chronic burrowing ulcer

Chronic burrowing ulcer is caused by?
A. Peptostreptococcus
B. Strep.pyogenes
C. Anaerobic streptococci
D. Microaerophilic streptococci

Correct answer : Anaerobic streptococci

A similar question was asked in AIPGMEE 07. But in that question, anaerobic streptococci was not provided as an option.

Bailey, 24th edition, p124 states that:
‘Synergistic spreading gangrene (necrotising fasciitis) is not caused by clostridia. A mixed pattern of organisms is responsible: coliforms, staphyolococci, Bacteroides spp., anaerobic streptococci and pepto-streptococci have all been implicated. Abdominal wall infections are known as Meleney’s synergistic hospital gangrene and scrotal infection as Fournier’s gangrene’

Meleney’s synergistic hospital gangrene is another name for chronic burrowing ulcer. Hence the correct answer is anaerobic streptococci instead of microaerophilic streptococci.
