RESUMO
A taxonomic study was carried out on a novel bacterial strain, designated MIC2059T, which was isolated from Ungok Wetland of Gochang in Korea. Cells of the isolate were found to be Gram-stain-negative, rod-shaped and motile. Comparison of the 16S rRNA gene sequences indicated that the isolate belonged to the family Rhodocyclaceae, with Uliginosibacterium gangwonense as its closest relative, with a similarity of 94.8 %. It contained summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0, summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c) and C12 : 0 3-OH as the major fatty acids and Q8 as the respiratory ubiquinone. The polar lipid profile of strain MIC2059T revealed the presence of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol as major polar lipids. In addition, phosphatidylserine, an unidentified aminophospholipid and unidentified lipids were present in small amounts. The DNA G+C content of the strain was 65.1âmol%. On the basis of the evidence presented, it is concluded that strain MIC2059T represents a novel species of a novel genus within the family Rhodocyclaceae, for which the name Niveibacterium umoris gen. nov., sp. nov. is proposed. The type strain is MIC2059T ( = KACC 17062T = JCM 18716T).
RESUMO
Several new technologies have been developed to improve the diagnostic capability of conventional endoscopic techniques. One of these most frequently used methods is chromoendoscopy with Lugol's solution in the esophagus to detect malignant lesions. This method has been used for several decades and is generally considered as a safe method, only a few cases of side effects having been reported. We describe a case of acute esophageal and gastric mucosal damage after application of Lugol's solution during endoscopy in an 84-year-old woman. Endoscopists should be aware of the potential for adverse reactions to iodine staining.
