Biotyping and resistotyping for tracing the fecal origin of Klebsiella pneumoniae strains associated with urinary infections

Twenty-four out of 29 patients suffering from hospital acquired urinary infections by K. pneumoniae had the same species in their faeces. Biotyping of 24 urinary and 219 fecal strains of K. pneumoniae resulted in 50 different biotypes - an average of four biotypes per fecal sample. Ten patients (34....

Description
Summary:Twenty-four out of 29 patients suffering from hospital acquired urinary infections by K. pneumoniae had the same species in their faeces. Biotyping of 24 urinary and 219 fecal strains of K. pneumoniae resulted in 50 different biotypes - an average of four biotypes per fecal sample. Ten patients (34.4%) had the same biotype in urine and faeces. Using resistotyping to four chemical compounds selected among 34 tested substances 16 different resistotypes were found. Fourteen patients (58.3%) presented the same resistotype in urine and faeces but only in five patients was there correlation with simultaneous biotyping identity. Simultaneous occurrence of identical biotypes or resistotypes in faeces and urine occurred in only 54.2% of cases. However, there was a significant association between resistance to mercuric and tellurite ions in fecal and urinary strains isolated from the same patient.
