Healthcare-associated infections (HAIs) have increased rapidly, and the wide spread of multidrug resistant (MDR) bacteria has made the control of HAIs a challenging health problem. Transmission of common pathogens from a colonized or infected patient to a susceptible patient has been reported to occur via the hands of healthcare personnel. Therefore, the priority of infection control policy has been allocated in hand hygiene program, contact precautions, and isolation. However, the transmission routes of pathogens are complicated. Furthermore, recent data suggest that the hospital environment could play a role as an important reservoir, and contaminated hospital surfaces, medical equipment, water, and air could be directly or indirectly involved in the transmission pathways. Therefore, we should reconsider the role of hospital environment control in the management of HAIs as well as developing strategies to reduce the contamination of hospital environment.

Plesiomonas shigelloides was isolated from blood culture of a 53-year-old man with fever, who had treatment history of gastrointestinal malignancy. The patient showed neither clinical features nor hematological finding which suggest bacteremia. Identification of the isolate was delayed because of its similar characteristics with Aeromonas spp. and other gram-negative bacilli. The isolate was misinterpreted as susceptible to ampicillin by the first disk diffusion test. It may not always easy to identify P. shigelloides by conventional tests and to determine its antimicrobial susceptibility accurately, as laboratorians rarely have experience with the organism and as the organism may show unusual inhibition pattern when tested by disk diffusion method or Etest.

BACKGROUND: A surveillance system for antibiotic resistance is well organized in both Japan and Korea; however, a comparative analysis by microorganism has not previously been conducted. METHODS: We compared the latest antibiotic resistance rates of medically important pathogens, such as Staphylococcus aureus, enterococci, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii, between Japan and Korea. Data were collected by JANIS (Japan Nosocomial Infections Surveillance) and KARMS (Korean Antimicrobial Resistance Monitoring System) from 2007-2012. RESULTS: In 2012, the proportions of oxacillin-resistant S. aureus, vancomycin-resistant Enterococcus faecium (VRE), cefotaxime-resistant E. coli, ceftazidime-resistant K. pneumoniae, imipenem-resistant P. aeruginosa, and imipenem-resistant A. baumannii were 53%, 0.4%, 16.6%, 2.9%, 18.5%, and 2% in Japan and 67%, 32%, 29%, 40%, 28%, and 70% in Korea, respectively. CONCLUSION: There were large differences in the frequencies of VRE, ceftazidime-resistant K. pneumoniae, and imipenem-resistant A. baumannii between Japan and Korea. A collaborative study to probe the differences in the antibiotic resistance rates between the two countries should be performed.

BACKGROUND: Workers in the microbiology laboratories are continuously exposed to the risk of laboratory-associated infections. Tuberculosis (TB) is a frequent laboratory-acquired infection owing to production of cough-generated aerosols with ease and high infectivity of Mycobacterium tuberculosis. This study aims to investigate the current situation of biosafety in Korean TB laboratories. METHODS: We conducted a nationwide survey of laboratories in hospitals conducting TB tests using questionnaires about their facility and management standards. RESULTS: We analyzed data from 52 hospitals nationwide that have a capacity of 100–2,000 beds, of which only two laboratories conduct high risk drug-susceptibility testing on cultured isolates among other test items, whereas six laboratories perform only direct sputum-smear microscopy. The remaining laboratories performed moderate-risk activities/tests, like sample processing for culture. In the majority of these laboratories, there are laboratory medicine specialists who are fully in charge of health checkup programs for laboratorians. The facility and management standards vary widely according to the size of the hospital and risk of TB tests. CONCLUSIONS: Our survey results about the current situation of TB laboratories could be useful as baseline data for preparing biosafety guidelines for all TB laboratories in Korea.

Neisseria gonorrhoeae is the causative agent of gonorrhea, one of the most important sexually transmitted diseases. The incidence of gonorrhea is still prevalent and about 50,000 new cases have been reported annually during the late 2000s in Korea. The antimicrobial resistance of N. gonorrhoeae is very prevalent and most isolates are multi-drug resistant to penicillin G, tetracycline, and fluoroquinolones. The incidence of penicillinase-producing N. gonorrhoeae (PPNG) decreased significantly, but high-level tetracycline-resistant N. gonorrhoeae (TRNG) increased recently. The minimum inhibitory concentrations (MICs) of ceftriaxone were within the susceptible range for all isolates, but MIC creep has been apparent and one cefixime-nonsusceptible isolate (0.5 microg/ml) was found. Spectinomycin-resistant isolates remain rare, but caution should be required when dealing with gonococcal pharyngitis.
