Incidence of Cutibacterium acnes from shoulder arthroplasties in Asians: ethnic differences should be considered.

Background: Most studies on Cutibacterium acnes in shoulder surgery have been conducted in the Western population, and studies on Asians are rare. We evaluated the incidence and risk factors of C acnes in shoulder arthroplasty in Asians.

Methods: We retrospectively analyzed 154 patients between January 2017 and May 2019 who underwent shoulder arthroplasty.

Minimally invasive multilevel lateral lumbar interbody fusion with posterior column osteotomy compared with pedicle subtraction osteotomy for adult spinal deformity.

Background Context: Pedicle subtraction osteotomy (PSO) is highly effective as a sagittal correction approach in patients with adult spinal deformity, but relevant issues such as surgical complexity and long-term complications limit its applicability. Recently, minimally invasive techniques have been reported to be useful for surgical treatment of adult spinal deformity; however, few reports have directly compared these techniques with PSO.

Purpose: The purpose of this study was to evaluate the radiological and clinical efficacies of oblique lateral interbody fusion (OLIF) with posterior column osteotomy (PCO) using stiff rods (6.

Recovery of plasmid pEMB1, whose toxin-antitoxin system stabilizes an ampicillin resistance-conferring β-lactamase gene in Escherichia coli, from natural environments.

Non-culture-based procedures were used to investigate plasmids showing ampicillin resistance properties in two different environments: remote mountain soil (Mt. Jeombong) and sludge (Tancheon wastewater treatment plant). Total DNA extracted from the environmental samples was directly transformed into Escherichia coli TOP10, and a single and three different plasmids were obtained from the mountain soil and sludge samples, respectively.

Aestuariibaculum suncheonense gen. nov., sp. nov., a marine bacterium of the family Flavobacteriaceae isolated from a tidal flat and emended descriptions of the genera Gaetbulibacter and Tamlana.

A Gram-staining-negative, yellow-pigmented, strictly aerobic bacterium, designated strain SC17(T), was isolated from sediment of a tidal flat of Suncheon bay in South Korea. Cells were halotolerant, catalase- and oxidase-positive and non-motile rods. Growth of strain SC17(T) was observed at 5-40 °C (optimum, 25-30 °C), at pH 6.

Kordiimonas aestuarii sp. nov., a marine bacterium isolated from a tidal flat.

A Gram-staining negative, strictly aerobic bacterium, designated 101-1(T), was isolated from a sea tidal flat, Taean, Korea. The strain formed small light-yellow, smooth, and circular colonies on marine agar. Cells were weakly halophilic, motile rods showing catalase- and oxidase-positive reactions.

Leuconostoc miyukkimchii sp. nov., isolated from brown algae (Undaria pinnatifida) kimchi.

A Gram-staining-positive, non-motile and non-spore-forming lactic acid bacterium, designated strain M2(T), was isolated from fermented brown algae (Undaria pinnatifida) kimchi in South Korea. Cells of the isolate were facultatively anaerobic ovoids and showed catalase- and oxidase-negative reactions. Growth of strain M2(T) was observed at 4-35 °C and at pH 5.

Metagenomic analysis of kimchi, a traditional Korean fermented food.

Kimchi, a traditional food in the Korean culture, is made from vegetables by fermentation. In this study, metagenomic approaches were used to monitor changes in bacterial populations, metabolic potential, and overall genetic features of the microbial community during the 29-day fermentation process. Metagenomic DNA was extracted from kimchi samples obtained periodically and was sequenced using a 454 GS FLX Titanium system, which yielded a total of 701,556 reads, with an average read length of 438 bp.

Pusillimonas harenae sp. nov., isolated from a sandy beach, and emended description of the genus Pusillimonas.

A Gram-stain-negative, motile bacterium with two lateral flagella, designated strain B201(T), was isolated from beach sand from the Taean coast in South Korea. Cells were ovoid rods and positive for catalase and oxidase. Growth of strain B201(T) was observed between 15 and 45 °C (optimum, 30 °C) and between pH 5.

Luteimonas lutimaris sp. nov., isolated from a tidal flat.

A Gram-staining-negative, strictly aerobic bacterium, designated strain G3(T), was isolated from a tidal flat of the Taean coast in South Korea. Cells were moderately halotolerant and non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain G3(T) was observed between 15 and 40 °C (optimum 30 °C) and between pH 5.

Citreicella aestuarii sp. nov., isolated from a tidal flat.

A Gram-negative bacterium, designated AD8(T), was isolated from a tidal flat of the Taean coast in South Korea. Cells were strictly aerobic, motile, ovoid rods or rods, with two lateral flagella on one side. Strain AD8(T) was catalase- and oxidase-positive and able to oxidize thiosulfate and reduce nitrate to nitrite.

Litorimicrobium taeanense gen. nov., sp. nov., isolated from a sandy beach.

A Gram-reaction-negative, strictly aerobic, non-motile bacterium, designated strain G4(T), was isolated from a sandy beach of Taean in South Korea. Cells were ovoid rods and were catalase- and oxidase-positive. Growth of strain G4(T) was determined at 15-35 °C (optimum 25-30 °C) and pH 6-8 (optimum pH 6.
