ABSTRACT
BACKGROUND: The latest region-specific panel of mycoplasma species is often crucial for providing insights into local mycoplasma epidemiology and updating clinical practice guidance. METHODS: We retrospectively reviewed reports of 4,166 female outpatients detected by the mycoplasma identification verification and antibiotic susceptibility kit from the last five years. RESULTS: Among them, > 73.3% of cases with Ureaplasma urealyticum or Mycoplasma hominis single infection or co-infection with both species were susceptible to three tetracyclines and one macrolide (josamycin). Additionally, > 84.8%, ≤ 4.4%, and ≤ 39.6% of the U. urealyticum, M. hominis, and co-infection cases, respectively, were susceptible to clarithromycin and roxithromycin. Four quinolones (ciprofloxacin, ofloxacin, sparfloxacin, and levofloxacin) and three macrolides (azithromycin, erythromycin, and acetylspiramycin) were active against < 48.9% of the isolates. Furthermore, 77.8%, 18.4%, and 7.5% of the M. hominis, U. urealyticum, and co-infection cases, respectively, were susceptible to spectinomycin. CONCLUSIONS: Tetracyclines and josamycin were the best antibiotics for most mycoplasma-infected patients.

BACKGROUND: Nucleic acid amplification tests (NAATs) are being used increasing to detection of CT (Chlamydia trachomatis) and NG (Neisseria gonorrhoeae) infections for superior sensitivity and specificity than other tests. Male first-void urine (FVU) sample is the optimal sample type for detection of CT and NG by NAATs. Although not being the recommended by NAATs, clinician-collected urethra swab (CCUS) is perhaps a good alternative sample type compared with the FVU sample in men. METHODS: Paired samples (FVU and CCUS) from one hundred male outpatients were simultaneously detected by urine pattern and swab pattern using cobas 4800 CT/NG assay on cobas 4800 system for the detection of CT and NG, respectively. And twenty-one positive controls were also detected on cobas 4800 system. RESULTS: The CT/NG cycle thresholds (Ct) value of urine pattern is lower than that of swab pattern for the same positive samples (clinical samples and positive controls) on the cobas 4800 CT/NG assay. The final CT/NG results of two sample patterns from patients were highly consistent except for four discordant results. CONCLUSION: CCUS is validated for a good alternative sample type for the CT/NG detection on the cobas 4800 system in this study.

PURPOSE: The aim of this study was to estimate the prevalence and antimicrobial susceptibility of Ureaplasma urealyticum and Mycoplasma hominis among female outpatients treated for genital infection at a Chinese hospital from January 1, 2009 to December 31, 2013. METHODS: Samples from 6051 female outpatients were analyzed using Mycoplasma Identification and Antimicrobial Susceptibility Testing (ID/AST). RESULTS: The overall prevalence of U. urealyticum was higher than the prevalence of single M. hominis infection (31.2% vs 0.7%) and coinfections (31.2% vs. 1.9%). The percentage of U. urealyticum and/or M. hominis detected in the 30-39 year age group was greater than in the other age groups. More than 94.6% of the U. urealyticum isolates, 100% of the M. hominis isolates, and 84.3% of the isolates from coinfections were susceptible to doxycycline, minocycline, and tetracycline. More than 69.2% of the U. urealyticum isolates were susceptible to azithromycin, erythromycin, clarithromycin, and roxithromycin, but > 95.6% of the M. hominis isolates and 89.6% of the isolates from coinfections were resistant to these antibiotics. Acetylspiramycin, sparfloxacin, levofloxacin, ciprofloxacin, and ofloxacin were inactive against more than one-half of the isolates. More than 75.6% of the M. hominis isolates were susceptible to spectinomycin, but > 87.1% of the U. urealyticum and 93.3% of the coinfection isolates were resistant to this antibiotic. Isolates from three coinfections were completely resistant to the 14 antibiotics. CONCLUSION: The determination of antimicrobial susceptibility of these mycoplasma species is often crucial for optimal antimicrobial therapy of infected outpatients.
