Friction-reduction effect of the hierarchical surface microstructure of carrion beetle by controlling the real contact area.

The discovery and elucidation of the surface microstructure functions of living organisms are crucial to resolving issues, such as friction. We newly discovered that , a type of carrion beetle that lives on the ground surface, exhibited a hierarchical surface microstructure comprising a submicron-sized wrinkle structure on top of a micron-sized microstructure. The surface microstructure of this beetle improved wettability but did not exhibit superhydrophobicity, a well-known function of hierarchical structures, so it was expected to have a different function.

Characterization of Shiga Toxin-producing Escherichia coli Isolated from Cattle Around Ulaanbaatar City, Mongolia.

Shiga toxin-producing Escherichia coli (STEC) are associated with severe infections including hemorrhagic colitis and hemolytic uremic syndrome in humans. Ruminants are known as reservoirs of STEC; however, no data are available on STEC in ruminants in Mongolia, where more than 5 million cattle and 25 million sheep are raised. To disclose the existence and characteristics of STEC in Mongolia, in this study, we isolated and characterized STEC from cattle in Mongolia.

Comparative whole-genome sequence analysis of a BoNT/B5-producing Clostridium botulinum isolate from an infant botulism case of unknown source in Osaka, Japan.

A case of infant botulism of unknown origin, not involved in honey consumption, occurred in Osaka, Japan in 2020. A Clostridium botulinum type B strain named Osaka2020 was isolated from a stool sample of the patient. To clarify the epidemiology of the case, we performed whole-genome sequencing (WGS) of the isolate and compared it with strains from other sources.

Chronic Diarrhea Associated with Edwardsiella Tarda Gastroenteritis: A Case Report and Literature Review.

Edwardsiella tarda , a Gram-negative bacterium classified into the genus Enterobacteriaceae, causes self-limited gastroenteritis. Here, we report a case of E. tarda gastroenteritis in a previously healthy 12-year-old boy in whom inflammatory bowel disease was precluded by endoscopy and tissue biopsy due to 3-month history of diarrhea, abdominal pain and weight loss.

COVID-19 in an Adult with Down Syndrome: Impact on Autoimmune Response.

We here report a case of COVID-19 with effusion prior to the development of pneumonia in an adult with Down syndrome. Serositis due to rheumatic disease was initially suspected because of a high titer of serum autoantibodies and leukocytopenia; however, SARS-CoV-2 infection was confirmed by reverse transcription polymerase chain reaction on admission after previous negative tests. Several cases of COVID-19 have been associated with autoimmune responses along with some cases of COVID-19 with autoimmune manifestations.

Infiltration of hidden antimicrobial resistance among healthy people in a Japanese community.

Background: Under non-antimicrobial selective pressure, antimicrobial-resistant bacteria do not easily become dominant in the microbiota. Furthermore, their low levels prevent detection by isolation, resulting in an underestimation of the prevalence of antimicrobial-resistant bacteria.

Objectives: We evaluated the infiltration of antimicrobial-resistant bacteria and their related β-lactamase genes among healthy people in non-clinical settings.

Multidrug-resistant Cutibacterium avidum isolated from patients with acne vulgaris and other infections.

Objectives: Cutibacterium avidum, a human skin commensal bacterium, rarely causes infections. It has recently been shown that Cutibacterium acnes, another member of the genus, acts as an opportunistic pathogen in surgical site infections. However, the antimicrobial susceptibility and pathogenicity of C.
