Abstract:Aim To study the status of bacteria L-form in urethral infection and the drug resistance.Methods The routine and hyperosmotic culture were performed on the samples of urethral infection.Results 142 Strains of bacteria L-form were separated out from the negative specimens on routine culture,the positive rate was increased by 24.7%.The first was CNS (26.8%),the second was E.coli (24.0%).Enterococus D group and S.aureus were 18.3%,14.8% respectively.The drug sensitivity results showed that they were high resistant to penicilin,and low to erythromycin,gentamicin and lincomycin.ConclusionsThe method step by step culture may not only increase the positive culture rate,but also provide very important clew in the diagnosis of doubtful cases and enhance the rational administration of antibiotics.
