1 VOLUME XXIII NUMBER 1 July 2008 CONTAGIOUS COMMENTS Department of Epidemiology Bugs and Drugs Elaine Dowell, SM (ASCP), Marti Roe SM (ASCP), Ann-Christine Nyquist MD, MSPH Are the bugs winning? The 2007 TCH annual antibiogram again shows an increase in resistant organisms that are not easily detected by standard testing methodologies. This requires clinical laboratories to develop new testing methods and staff expertise to recognize them. Although we have added MRSA to our daily vocabulary, both gram negative and gram positive organisms have shown increasing rates of new mechanisms of resistance. MRSA continues to increase in both our emergency departments (including Network of Care, Urgent Care and the Child Health Clinic) and our inpatient population. Because of the implications of the spread of this resistant organism, TCH s Microbiology laboratory is validating a new PCR assay on our GeneXpert that will allow faster screening of high risk patients. This faster screening will allow isolation precautions to be shortened for MRSA negative patients. The D test has been used for several years to detect the erm gene that confers inducible clindamycin resistance to Staphylococcus aureus. The D test is performed prior to reporting clindamycin susceptibility for S. aureus. The erm gene is also found in Group A streptococcus and is automatically tested in our lab prior to reporting susceptibilities. In 2007, 22 Group A strep isolates were tested with none showing the inducible erm gene that would indicate clindamycin resistance. Our number of VRE (Vancomycin Resistant Enterococcus) isolates, although low, has increased from one in 2006 to five in VRE has been isolated from significant sources and we reported our first blood culture isolate this year. Gram negative bacteria also continue to mutate and acquire new resistance enzymes that are not easily detected by standard susceptibility testing. Perhaps the most challenging for the laboratory has been Extended-Spectrum Beta Lactamases (ESBLs). Typically, ESBLs are mutant, plasmid-mediated beta-lactamases derived from older broad spectrum beta-lactamases which have extended substrate profiles that permit hydrolysis of all cephalosporins, penicillins, and aztreonam. The production of AmpC beta-lactamases by gram negative bacteria further complicates susceptibility testing. AmpC beta lactamases differ from ESBLs in that they are cephalosporinases and confer resistance to beta lactamase inhibitors. AmpC is normally produced in low levels by many gram negative organisms and is not associated with resistance. When AmpC is produced at high levels there is resistance to all beta-lactams except carbapenems and 4 th generation cephalosporins (e.g. Cefipime). ESBL (Extended-Spectrum Beta Lactamase) isolates this year have showed a significant increase from 3 to 13. The majority of these isolates were from urine specimens, but one isolate was from a blood culture. In Table 1, Enterobacter cloacae urine isolates showed a marked decrease in susceptibility and differed from the non-urine isolates. This phenomenon of decreased susceptibility of this organism in non-icu units has been reported at other institutions and is making an impact on patient care. (see page 2 for Table 1.)

3 TCH s microbiology laboratory will be validating new susceptibility testing panels that will detect ESBLs in CLSI recommended organisms including: E. coli, Klebsiella species, and Proteus mirabilis. Having the confirmatory assay within the panel will shorten the turnaround time to a final report by a day and will also allow us to screen for ESBLs in Enterobacter cloacae. The bugs continue to put up a good fight as the antibiotic arsenal is decreasing. What can you do? 1. Obtain good specimens to send to the microbiology lab for culture. This translates to fluid samples where a gram stain may be done and avoiding the use of swabs for culture. 2. Check microbiology culture results and susceptibility patterns so that you can make sure you are treating with an appropriate antibiotic. 3. Use a narrow spectrum antibiotic when possible to decrease antibiotic pressure and development of resistance. 4. Prevent infection by practicing tried and true good infection control practices: protect yourself and your patient by adhering to isolation precautions and by all means wash your hands.
