The antibiotic susceptibility of Neisseria gonorrhoeae isolated in Ulaanbaatar, Mongolia

Isolates were serotyped by their co-agglutination reactions with a panel of 14 monoclonal antibodies (Boule Diagnostics, Huddinge, Sweden) using the nomenclature of Bygdeman. 5 Auxotyping was performed by standard methods. 4 Results The susceptibility patterns of the 56 strains to the antibiotics tested are shown in table 1. The E-test method was unreliable for estimating the susceptibility of gonococci to gentamicin. 6 Criteria for establishing resistance of gonococci to gentamicin by disc diffusion testing methods are yet to be established and would require the availability of gonococci with higher MICs than were present in this sample.
