Detection situation of L-form bacteria in urinary calculi and drug resistance / 国际检验医学杂志

Objective To investigate the infection situation of L-form bacteria in urinary calculi from the patients with urolithia-sis in a hospital to provide a scientific basis for postoperative anti-infection and prevention of urinary stone recurrence.Methods The calculi samples in 265 cases of urinary calculi from October to December 2015 were collected and performed the culture of com-mon bacteria and L-form bacteria respectively.Culture of common bacteria and bacterial L-forms.Results Among 265 cases of uri-nary calculi ,8 cases(3% ,8/265) were L-form Bacterial combined with common bacterial infection ,only 7 cases(2.6% ,7/265) were L-form bacterial infection ,80 cases (30.0% ,80/265) were common bacterial infection.15 strains of L-form bacteria were detected and 96 strains of common bacteria were detected.The drug resistance of L-form bacteria was significantly increased compared with common bacteria.Conclusion The positive rate of L-form bacteria culture of urinary calculi is lower than other domestic reports. Adding hypertonic medium for conducting L-form bacterial isolation and culture in the patients with urinary tract infection can re-duce the false negative.
