A case of arthritis due to a penicillinase-producing Neisseria gonorrh
oeae in a 29-year-old lady is reported. The organism was isolated from
the synovial fluid of the affected joint. Isolation of penicillinase-
producing N. gonorrhoeae from such fluid has only rarely been reported
. However, this is probably the first reported case from the Middle Ea
st and surrounding areas.
