Antibiotic resistance, haemagglutination type & haemolysin production in relation to serogroups of uropathogenic Escherichia coli.

A total of 56 urinary isolates of Esch. coli were characterised according to serotype, haemagglutination (HA) type, production of beta haemolysin and antibiotic resistance pattern. Forty five strains were serotyped with prevalence of 057 followed by other serotypes. Eleven different Esch. coli serotypes were found to have mannose resistant haemagglutinating property (MRHA) and just five strains showed haemolysin production (Hly+). Multidrug resistance was common with preponderance of ampicillin, co-trimoxazole and tetracycline resistance. No correlation between serogroup, HA type, haemolysin production and antibiotic resistance was found.
