Frequency and clinical characteristics of mycoplasma urinary tract infections in the early post-transplantation period in renal allograft patients.

Using a highly sensitive and specific polymerase chain reaction (PCR) protocol, we studied 36 renal allograft recipients and 30 healthy controls. Midstream urine samples were analyzed using routine microbiological methods and the Mycoplasma IST (BioMerieux, France). Mycoplasma infections of the upper urinary tract were found in 9 patients. In three of them E.coli and Proteus were also present. We discuss the clinical characteristics of mycoplasma infections in the early post-transplantation period and its possible implications for graft rejection.
