    Notes: Abstract  The minimum inhibitory concentrations (MICs) of mupirocin were determined by the E test (AB Biodisk, Sweden) and the agar dilution method for 107 staphylococci. The organisms consisted of 34 coagulase-negative staphylococci and 73 methicillin-resistant Staphylococcus aureus. Polymerase chain reaction (PCR) primers designed to amplify a 456 bp region of the plasmid-borne isoleucyl tRNA synthetase gene (ileS–2), responsible for high-level mupirocin resistance in staphylococci, were used on DNA preparations from these isolates. Isolates with high-level mupirocin resistance due to the ileS–2 gene should be PCR positive. There was close correlation between the E test and agar dilution MIC values, with only two strains differing by more than two serial dilutions. Most (51 of 54 strains) of the high-level resistant strains (MIC〉256 μg/ml) were resistant to the highest concentration of mupirocin tested (1024 μg/ml). PCR correctly classified all but four (96%) of the isolates in accordance with the results of agar dilution. All four isolates that gave discrepant results were methicillin-resistant Staphylococcus aureus. Two of these were PCR positive, yet the MIC of mupirocin for these strains was 〈0.06 μg/ml; on prolonged incubation they produced halos within the inhibition zone on agar diffusion testing, suggesting that the phenotypic results may have been erroneous. One of 54 isolates for which the MIC exceeded 256 μg/ml was PCR negative when tested by the original methodology, but a 456 bp product was produced when retested using a lowered annealing temperature. One isolate for which the MIC of mupirocin was 16 μg/ml by agar dilution and 8 μg/ml by the E test was positive by PCR. PCR of the ileS–2 gene is a useful, rapid method for detecting high-level mupirocin resistance in staphylococci.

    Notes: Abstract  During a 1-month period in 1996, all inpatients and staff in the Zagreb Trauma Hospital were screened for methicillin-resistant Staphylococcus aureus (MRSA) carriage in order to control MRSA spread within the hospital. During the study period, 663 patients were admitted to the hospital, and screening prior to discharge revealed that 42 were colonised or infected with MRSA. Twenty-three (55%) of these would not have been detected if active screening had not been performed. Amongst 205 staff members, MRSA carriage was only found in one (0.5%) nurse. The prevalence and incidence of MRSA carriage varied significantly amongst the wards and was related to the length of hospital stay. One-third of the patients colonised or infected with MRSA had a history of previous admission to another hospital, and one-third were transferred to another institution after discharge. Thirty-nine of 42 MRSA isolates shared the same antibiotic sensitivity pattern, suggesting endemic spread of MRSA. However, randomly amplified polymorphic DNA molecular typing revealed four profiles, the most common involving 15 of 36 tested strains. There was no obvious clustering of epidemiological types by ward, except for the appearance of a single type on the burns unit, and it was likely that different strains had been introduced into the hospital by patient transfers from elsewhere. The results of this study indicate that a substantial proportion of MRSA carriers escape infection control measures if active screening is not performed. Based on the results of this study, steps have been taken to improve interhospital communication about the transfer of patients colonised with MRSA. Randomly amplified polymorphic DNA typing proved to be a useful aid to epidemiological investigations of MRSA.
