Microbial Contamination Characteristics on Touch Surfaces in Outpatient Self-Service Facilities.

BACKGROUND: With the development of science and technology, self-service facilities have been widely used in hospitals. This study aimed to assess the microbial contamination characteristics on touch surfaces in outpatient, self-service facilities from Monday to Friday. METHODS: Touch surfaces in outpatient facilities were swabbed and surveyed for total microbial growth before and after work every morning. Selected bacteria were identified to screen for pathogenic organisms. RESULTS: There were 360 samples collected, 87 samples (24.2%) were culture-positive. Staphylococcus species were the main microbial contamination. The three most common bacteria were S. hominis, S. epidermidis and S. hemolyticus. After work, more microbial contamination was found on Monday (p = 0.029). There was no difference in sample positive rates between self-service facilities and manual service area. Although, the antibiotic resistance patterns of different staphylococcus species were different, the overall drug resistance rate is low. Only one S. aureus was methicillin-Sensitive S. aureus. CONCLUSIONS: The self-service facilities' touch surfaces microbial contamination were similar to manual service area, but the more used, the more microbial contamination was found. Hospitals should enhance cleaning times of self-service facilities to keep them clean, especially on Mondays.

Rare Meningitis and Epileptic Seizure Infected with Brucella melitensis: a Case Report.

BACKGROUND: Although brucellosis is the most common zoonotic disease worldwide, human meningitis infected with Brucella melitensis is rare and difficult to diagnosis. Herein we describe the clinical aspects of a rare case of Brucella melitensis meningitis accompanied by epileptic seizure. METHODS: Bacterial culture of CSF was utilized to find the pathogen. Serum and CSF agglutination tests were used to detect the capacity of Brucella antigen. Bacterial clone was identified by the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF). Magnetic resonance imaging (MRI) was used to monitor the recovery changes for meningitis. RESULTS: The bacterial culture was positive for Brucella app. Antigen-antibody agglutination test was also positive with a titer more than 1/200. A reliable identification score of 2.8 for Brucella melitensis was obtained by MALDI-TOF. MRI showed obviously improved meningitis after therapy. CONCLUSIONS: The results of this study suggest the treatments for Brucella meningitis must be planned depending on the patient's clinical conditions and the laboratory identification of pathogen infection as early as possible.
