Bare-legged Swiftlet

The Bare-legged Swiftlet (Aerodramus nuditarsus) is a species in the genus Aerodramus. It is currently classified as Least Concern on the IUCN Red List. Typically found in various aerial, terrestrial, and aquatic environments.

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.
