Mycobacterium massiliense which is recognized as a separate species from M. abscessus is little known regarding its clinical patterns and the response to treatment. We present a case of a localized cutaneous infection due to M. massiliense of the sole associated with acupuncture. M. massiliense was identified via polymerase chain reaction-hybridization analysis. We treated the patient with single-drug therapy consisting of clarithromycin for 4 months and the patient showed a significant response to this treatment.

BACKGROUND: The emergence of metronidazole (MTZ) resistance among Helicobacter pylori (H. pylori) isolates has compromised the efficacy of the triple therapy. Therefore, special attention should be given toward reliable methods for determining the in vitro susceptibility. But susceptibility testing of H. pylori is not yet either standardized or routinely performed. The purpose of this study was to establish more reliable, but simple to perform and cost-effective antimicrobial susceptibility testing method. METHODS: With 135 clinical isolates of H. pylori, antimicrobial susceptibility tests for MTZ and clarithromycin (CLR) were performed by antibiotic gradient method (E test, AB BIODISK, Sweden) and disk diffusion method (disk method), and the results were compared with the reference modified broth microdilution method (broth method). RESULTS: Resistant rates of Korean isolates of H. pylori for MTZ and CLR were 46.2% and 2.2%, respectively. There was 100% agreements between the E test, disk method and the broth method for CLR. For MTZ, however, agreements between the results obtained by the three methods were variable. Between the E test and broth method, the agreements were 85.1% in terms of susceptibility categories, 80.5% between the disk and broth method, and 93.1% between the E test and disk method. CONCLUSIONS: Routine susceptibility testing of H. pylori to MTZ seems to be required in Korea. The broth method is recommended for MTZ until more accurate, simple and practical alternative method become available. For the CLR, the disk method is recommended, because it is reliable, simple, and economical.

Mycobacterium massiliense, an emerging pathogen that is increasingly reported as a causative agent in infections occurring during medical procedures, is difficult to be identified using conventional methods. Here we report the case of a cutaneous M. massiliense infection that was associated with repeated surgical procedures and that was identified via a comparative sequence analysis of rpoB and hsp65. The patient showed a substantial response to treatment with a combination of antimicrobial therapies consisting of clarithromycin, amikacin, and cefoxitin for 6 months.

BACKGROUND: CLSI provides a guideline only for a agar dilution method of testing clarithromycin susceptibility for Helicobacter pylori. This study was to evaluate a disk diffusion method for clarithromycin and amoxicillin. METHODS: One hundred and forty clinical isolates of H. pylori isolated from May 2005 to May 2007 were tested by the CLSI agar dilution method and a disk diffusion method using 2microgram (2CLR) and 15microgram (15CLR) clarithromycin disks and 2microgram (2AMX) and 10microgram (10AMX) amoxicillin disks. The interpretation criteria used for the disk diffusion method were established by linear regression and error rate-bounded method for disk diffusion zone of inhibition (DDZ) compared to MIC. RESULTS: Resistance and intermediate rates to clarithromycin were 21.4% and 1.4%, respectively. A number of isolates with MIC 0.5, 1, and 2 (microgram/mL) to amoxicillin were 7, 2, and 1, respectively. For 2CLR and 15CLR, the coefficients of determination (R2) between MIC and DDZ were 0.931 and 0.923 (P< 0.001), respectively, and the criteria for resistance/ susceptibility were 12/28 mm for 2CLR and 23/39 mm for 15CLR. For 2AMX and 10AMX, the R2 between MIC and DDZ were 0.478 and 0.421 (P< 0.001), respectively, and the criteria for resistance with breakpoint of 2microgram/mL were 21 mm for 2AMX and 32 mm for 10AMX. All isolates had DDZ<60 mm with 2CLR and 2AMX, but 61.4% and 75.7% of the isolates had DDZ<60 mm with 15CLR and 10AMX, respectively. CONCLUSION: Excellent correlation and agreement between MIC and DDZ were found for clarithromycin and amoxicillin. With 2microgram disks, the susceptibility breakpoints were 28 mm or less; thus, two disks could be tested in one plate.
