A penicillinase test incorporated in the rapid carbohydrate fermentation method for rapid detection of beta-lactamase producing Neisseria gonorrhoeae.

A modification of the acidometric (phenol red) test for penicillinase producing N. gonorrhoeae was incorporated into the rapid fermentation method for rapid screening and identification of PPNG strains. Two hundred and twenty-four non-penicillinase-producing N. gonorrhoeae, 55 penicillinase-producing N. gonorrhoeae, 87 N. meningitidis and 89 N. lactamica were included in this study. Results of the modified test were comparable with the iodometric and penicillin disk diffusion susceptibility and were obtainable within 1 to 5 minutes.

Susceptibility of Neisseria gonorrhoeae isolates from Jakarta, Indonesia, to antibiotics.

The minimum inhibitory concentration (MIC) of penicillin, tetracycline and spectinomycin was determined for 6 beta-lactamase (PPNG) and 73 non beta-lactamase producing Neisseria gonorrhoeae isolates from Jakarta, Indonesia. All PPNG were resistant to greater than or equal to 128 micrograms/ml penicillin. Forty-six percent of the non-PPNG strains were inhibited by less than or equal to 1.0 microgram/ml of penicillin and 97% by less than or equal to 4 micrograms/ml. Most of the PPNG and non-PPNG isolates (90%) were inhibited by less than or equal to 4 micrograms/ml tetracycline and less than or equal to 16 micrograms/ml spectinomycin. Two non-PPNG strains were resistant to 64 micrograms/ml of tetracycline, 8 micrograms/ml penicillin and 32 micrograms/ml spectinomycin. The non-PPNG strains generally were more resistant to penicillin and tetracycline compared to strains tested from other parts of the world in previously reported studies.

A survey of scrub and murine typhus in the Ancol section of Jakarta, Indonesia.

Rickettsia tsutsugamushi was isolated from L. (L.) arenicola chiggers and three species of rats in an area of scrub and sedge along the Bay of Jakarta. This is the only finding in Indonesia of a cycle of the agent of scrub typhus associated with L. (L.) arenicola. A serologic survey of nearly 300 persons living in two kampungs near the site at which rickettsiae were recovered revealed one individual with antibodies to R. tsutsugamushi. Murine typhus, with a seropositivity rate of 6.5%, may be endemic at low levels.

Neisseria gonorrhoeae and penicillinase producing N. gonorrhoeae among some patients in Jakarta Indonesia.

Neisseria gonorrhoeae was isolated from 14 out of 50 (28%) of one group and 35 out of 60 (58%) of a second group of females in different areas of Jakarta, Indonesia. four (7%) of the patients in the second group were infected with penicillinase producing Neisseria gonorrhoeae (PPNG). This may be the first reported isolation of PPNG in Indonesia.
