the failure rate with thiamphenicol was significantly higher than that with spectinomycin ( 2 g im ) in the treatment of infections due to beta-lactamase-producing n. gonorrhoeae but was essentially similar to that observed with aqueous procaine penicillin g ( 4.8 x 10 ( 6 ) units im ) plus probenecid ( 1 g perorally ) among non-beta-lactamase-producing n. gonorrhoeae .
