Sturgeon aqua-cultured in Korea is mainly Acipenser ruthenus and its culture began in the early 2000's. In this study, Carnobacterium sp. was isolated from unprocessed caviar of aqua-cultured Acipenser ruthenus. The 16s rRNA nucleotide sequence obtained from Carnobacterium sp. isolate (accession no. KM236206) was deposited with GenBank and homologous with Carnobacterium divergens DSM 20623 and NBRC15683 strain. In conclusion, this is first report of isolation of Carnobacterium sp. from caviar of Acipenser ruthenus aqua-cultured in Korea. In the future, it must be ascertained whether Carnobacterium sp. degenerate of caviar or cause diseases in sturgeon.

Dental professionals are repeatedly exposed to many microorganisms present in both blood and saliva. Thus, dental professionals are at a greater risk of acquiring and spreading infections, and the implementation of infections control guidelines is necessary. Cellular phones have become a necessary device for communicating in hospitals. Cellular phones contaminated with bacteria may serve as a fomite in the transmission of pathogens by the hands of medical personnel. Nevertheless, studies about rate and levels of bacterial contamination of cellular phones have been extremely limited with regards to dental personnel. The purpose of this study was to identify bacterial flora on the cellular phones of dentists by a molecular biological method using the 16S rRNA cloning and sequencing method. We acquired total 200 clones from dentists' cell phones and identified the bacterial species. Pseudomonas (34.6%), Lactobacillus (18.5%), Azomonas (11.5%), and Janthinobacterium (6%) were the dominant genera on dentists' cell phones. The oral bacteria identified were Anaerococcus lactolyticus, Gibbsiella dentisursi, Lactobacills leiae, Streptococcus mitis, Streptococcus oligofermentans, and Streptococcus sanguinis. Pathogenic bacteria and opportunistic pathogens such as Carnobacterium funditum, Raoultella planticola, Shigella flexneri, Lactobacillus iners, Staphylococcus aureus, and Staphylococcus epidermidis were also identified.
