Two Gram-stain-negative cocci anaerobes were isolated from pig faeces and designated as strains YH-vei2232 and YH-vei2233. Phylogenetic analysis using 16S rRNA gene sequences revealed that the isolates were most closely related to KCTC 5967, with 97.0% similarity.

Article Synopsis
  • A new bacterium strain, named YH-ols2223, was isolated from pig feces and is classified as a short-rod, Gram-positive, obligate anaerobe.
  • Genetic analysis shows it has 97.7% similarity to KCTC 25755 and forms a unique sub-cluster within its genus.
  • The bacterium produces lactic and acetic acids during fermentation and has a distinctive peptidoglycan structure, leading to its designation as a novel species.

Article Synopsis
  • Scientists wanted to see if the germs in saliva could show changes in gum disease after treatment.
  • They took samples from healthy people and those with different levels of gum disease, then tested the germs in their saliva and under their gums.
  • The results showed that saliva germs can reflect changes in gum health, so it might be used to help check for gum disease in the future.

Periodontal disease (PD) is caused by microbial dysbiosis and accompanying adverse inflammatory responses. Due to its high incidence and association with various systemic diseases, disease-modifying treatments that modulate dysbiosis serve as promising therapeutic approaches. In this study, to simulate the pathophysiological situation, we established a "temporary ligature plus oral infection model" that incorporates a temporary silk ligature and oral infection with a cocktail of live (), (), and () in mice and tested the efficacy of a new trivalent mucosal vaccine.

The optimal indoor environment is associated with comfortable temperatures along with favorable indoor air quality. One of the air pollutants, particulate matter (PM), is potentially harmful to animals and humans. Most farms have monitoring systems to identify other hazardous gases rather than PM due to the sensor cost.
