  • Proteus syndrome is a congenital hamartomatous malformation that is characterized by a wide range of deformities, including craniofacial deformities. Proteus syndrome features partial gigantism and asymmetry of the limbs, plantar hyperplasia, hemangiomas, lipomas, lymphangiomas, varicosities, verrucous epidermal nevi, macrocephaly, cranial hyperostosis, and long bone overgrowth. We diagnosed Proteus syndrome in a male patient who visited our hospital with a chief complaint of limited mouth opening and report the case because we obtained a good healing outcome after treating the condition with a corrective osteotomy.

  • Direct Sky Blue-5B is an Azo dye known as general for staining of textile and leather, etc., and as materials which are difficult to be biodegraded in nature. The bacterium strain which could degrade direct Sky Blue-5B was isolated from activated sludge of dyeing factory and identified as Proteus sp. by experiment on morphological, cultural and biochemical characteristics, and so named Proteus sp. ST-1. The optimum condition of the strain for degradation of Sky Blue-5B were at about 35$^{\circ}C$ and PH 7~8. The strain had been capable of degradation with organic nitrogen effectively and had completely degraded 200mg/1 of the dye within 12hrs at 37$^{\circ}C$. The enzyme system related to degradation of Azo dye may be intracellular, and so degraded the dye after absorption into cell. The degradation products of Sky Blue-5B by Proton sp. 57-1 were analyzed by Gas Chromatography /Mass Spectrometry and Spectrophotomer, from this observation, it may be infered that the strain degraded the dye directly without any mediate.

  • The bio-electrode for cytosine has been constructed by immobilizing Proteus mirabilis and Citrobacter freundii on an ammonia gas-sensor. Bacteria containing cytosine deaminase convert one molecule of cytosine into one molecule of ammonia. The Proteus mirabilis bacterial electrode showed linear response to cytosine concentration in the $1.0{\times}10^{-3}\;-\;5.0{\times}10^{-2}$M with a slope of 45-48 mV/decade in 0.2 M phospbate buffer solution at pH 8.4. The Citrobacter freundii bacterial electrode showed linear response to cytosine concentration in the $7.0{\times}10^{-5}\;-\;7.0{\times}10^{-3}$M with a slope of 48 mV/decade in 0.05M phosphate buffer solution at pH 7.6. These electrode were investigated for the effects of pH, temperature, buffer solutions, amounts of bacteria, interferences, inorganic salts and lifetime.

  • Strain BCNU 2001 was isolated from soil samples collected from Tea-baek Mountain area. The biochemical characteristics and 16S ribosomal RNA gene sequences of the isolate revealed that the strain belonged to the Pseudomonas aeruginosa. The supernatants had an antimicrobial effect on various kind of bacteria and fungi. Especially BCNU 2001 was able to greatly inhibit the growth of Micrococcus luteus, Proteus mirabilis, Proteus vulgaris, and Aspergillus niger, and its inhibition zone was measured as 18.5 mm against Micrococcus luteus, 19.0mm against Proteus mirabilis, 17.0mm against Proteus vulgaris, and 13.5 mm against Aspergillus niger, respectively. Hexane and dichloromethane extracts of BCNU 2001 exhibited significant activity against bacteria, and dichloromethane and ethylacetate extracts showed significant activity against fungi. Pseudomonas strain BCNU 2001 was also determined to have antimicrobial peptide against various microorganisms including Gram positive bacteria, Gram negative bacteria and fungi. The obtained results may provide preliminary support for the usefulness of Pseudomonas strain BCNU 2001.

  • Antimicrobial agents or additives have commonly been used in domestic animals for the prevention and treatment of bacterial diseases. Unfortunately, this has resulted in the overgrowth of bacteria that is resistant to antimicrobial agents used by humans, and these might get disseminated to humans via the food. In this study, we investigated the prevalence of integrons, and characterized gene cassette arrays in Proteus mirabilis isolates obtained from chickens in Chungcheong province of Korea. Additionally, the correlation between gene cassette arrays and antimicrobial resistance rate was studied. A total of 26 Proteus mirabilis isolates were recovered from chickens in Chungcheong province in Korea. Antimicrobial susceptibility was determined by disk diffusion method. PCR and DNA sequencing were performed to characterize the gene cassette arrays. In addition, we employed repetitive extragenic palindromic sequence-based PCR (REP-PCR) method for clonality analysis of P. mirabilis strains. Of the 26 P. mirabilis isolates tested, 14 (53.8%) isolates carried class 1 integrons, while class 2 and class 3 integrons were not detected in our study. The class 1 integrons harbored genes encoding resistance to aminoglycosides (aacCA5, aadA2, aadA5 and aadA7), trimethoprim (dfrA17, and dfrA32), lincosamides (linF) and erythromycin (ereA). In particular, the presence of class 1 integron had a significant correlatation to a high resistance rate of aminoglycoside and trimethoprim. We confirmed that class 1 integrons are widely disseminated in P. mirabilis isolates from chickens, contributing to the resistance to diverse antimicrobial agents in Korea. To prevent further spreading of antimicrobial resistant genes among P. mirabilis isolates, constant monitoring and clinical policing will become necessary.

  • The dog breeding kennel bacterial infection are very significant in perinatal mortality. In many case, Staphylococcus aureus, Streptococcus, and Escherichia coli were infected in intra-uterine or by the genital tract to the puppies, and they are cause of septicemic death of the puppies and clinical mastitis of bitch, leading to septicemic death of newborn puppies. Severe mastitis due to bacterial infection was diagnosed in a 2 year-old female Brittany Spaniel which loss 6 puppies with odor small rice sharp white diarrhea of nine puppies. Bright curd milk and intestinal sample were inoculated on MacConkey agar, blood agar and brain heart infusion agar, and incubated at $37^{\circ}C$ for 24-48 hrs. Gram negative colonies isolated from these sample which were characterized as Glu, Ure, $H_2S$, Orn, Cit, and Cl, and were identified by Microscan Walk-Aways Baxter, American Type Culture Collection, USA) as Proteus mirabils. The isolate was more sensitive to ampicillin, gentamicin, cefoxitin, cefuroxime, and cefazidime. In this results, we confirmed that cause bacteria of septicemic death in puppies was P. mirabilis.
