A 2-year-old female Pomeranian dog was referred with multiple pelvic fractures. The surgical correction was performed for the fractures. However, after the surgery, purulent exudation was occurred in the surgical site. Antibiotic susceptibility test revealed that the isolated bacteria are resistant to penicillins, cephalosporins, aminoglycosides, quinolones, and trimethoprim/sulfamethoxazole. Bacterial identification and extended-spectrum $\beta$-lactamase (ESBL) confirming test indicated that the isolated bacteriae is ESBL-producing Klebsiella pneumoniae. Minimum inhibitory concentration (MIC) and maximum bactericidal concentration (MBC) tests revealed that meropenem, one of carbapenems, is the only effective antibiotic. The patient was treated with meropenem for 5 days. After 10 days, the exudation was disappeared and the infection was cured. The molecular typing of the ESBL revealed that TEM-1 ESBL is present in the bacteria isolated from the patient. The bacteria isolated from the owner's palm also revealed that TEM-1 and SHV-1 ESBLs are present.

Cellular phones are the most used electronic device everyday in modern life and are always in contact with our hands, Although many studies have revealed microorganisms living on our hands, there are only a few reports on the research about products or places which are in contact with our hands. Therefore, the purpose of this study is to verify microorganisms living in cellular phones. Microorganisms were scraped from cellular phones of students and professors from the clinical laboratory science department in Daegu Health College, and cultured at Brain Heart Infusion agar and MacConkey agar following API kit to identify them. The average colony number was $1.5{\times}10^2$ on BHI agar and $40{\times}10$ on MacConkey agar. There was no difference according to gender. In Gram stain result, Gram(+) Cocci showed the highest frequency. Also in BHI agar plates, Micrococcus spp and Acinetobacter baumannii identified with high frequency. Moreover, S. aureus, which is very well known as strong food poisoning bacteria, was isolated. Klebsiella pneumonia ssp pneumonia was isolated with the highest frequency from the MacConkey agar or S-S agar plate. From these results show, there are as many different microorganisms from cellular phones as from our hands. This is the first report isolating strong food poisoning bacteria in cellular phones. Since infection in hospitals have been an important issue to be aware of, it is equally necessary to investigate cell phones and products which hospital workers touch with their hands.

The purpose of this study is to investigate the optimal dyeing conditions and human-friendly properties of the extract from the branches of Alnus firma tree which is widely used for forestation and to provide basic information for quantification and commercialization of natural dyeing by discovering such as dye material. The optimal dyeing conditions, as a result, were shown at 100% of dye concentration, $90^{\circ}C$ of dyeing temperature and 40 minutes of dyeing time. In terms of dye uptake depending on the mordanting methods, it showed the best result in order of Fe, Sn, Cu and Al at pre-mordanting while found strong in order of Fe, Cu, Al and Sn at post-mordanting. Color fastness to washing and dry cleaning was found strong at grade 4-5 and fastness to light was rated at 2. The grade of change in color to rubbing and perspiration was good at 4-5. In aspects of functional properties, it showed excellent results of 98% deodorization rate at 120 minutes of dyeing time, 96.1% UV protection rate and 99.9% bacterial reduction against Staphylococcus aureus and Klebsiella pneuminiae. It is considered, therefore, the extract from Alnus firma tree is of great value as an eco-friendly natural dyestuff.
