Clostridium carnis is an anaerobic, endospore-forming bacterium in the family Clostridiaceae typically isolated from meat (caro/carnis, Latin for meat) and animal tissues, as well as soil and sediments. Like other clostridia, it is a strictly anaerobic, Gram-positive rod that survives adverse conditions by forming heat-resistant endospores. C. carnis is associated with putrefaction processes in proteinaceous substrates, producing proteolytic enzymes that break down meat proteins, contributing to gas gangrene and tissue necrosis in infected wounds under anaerobic conditions. It is considered one of the histotoxic clostridia capable of causing wound infections in humans and animals, though it is less clinically significant than C. perfringens or C. septicum. Isolated from soil, intestinal contents, and meat products, C. carnis contributes to anaerobic decomposition of organic nitrogen compounds, releasing ammonia and simpler organic acids back into the environment. Its resistance to environmental conditions through sporulation makes it persistent in soil environments associated with animal husbandry and meat processing facilities.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
