Extracts from such a system would thus contain only meningococcal enzyme, and sulfonamide effects on mutated forms of this enzyme could then be measured specifically and precisely. It was shown that the Ki value for sulfonamide (in this case, sulfathiazol), which is a quantitative measure of the affinity of the inhibitor for the enzyme, showed good correlation with the MIC values assessed (Fig. 4). The amino acid exchange of resistance Leu31 to susceptibility 31Phe caused an almost 400-fold decrease in the Ki value for sulfonamide.

Streptothricin resistance plasmids were furthermore found in E. coli isolated from the gut and from the urinary tracts of people with no connection to pig farms but living in villages and towns in an area where streptothricin was used in animal husbandry. These examples illustrate the rapid emergence of antimicrobial resistance and their powerful mechanisms CONTROL OF ANTIBIOTICS OVERUSE 27 of spread. Further investigation showed that the plasmid-borne gene mediating streptothricin resistance was in turn borne on a transposon on the plasmid.

A simple interpretation of their role in resistance has not been possible. SULFONAMIDES 49 Resistance to Sulfonamides in Mycobacterium leprae Dapsone (4,4 -diaminodiphenyl sulfone), microbiologically a sulfonamide (see 3-3), has been a standard remedy in leprosy treatment for a long time, and sulfonamide resistance in the form of three chromosomal mutations in the folP gene has been defined. At present, rifampicin (see Chapter 9) is the drug of choice for the treatment of leprosy. Plasmid-Borne Resistance to Sulfonamides Sulfonamide insusceptibility was one of the first antibiotic resistance traits found to be transferable (see Chapter 10).
