The fire salamander's primary alkaloid toxin, samandarin, causes strong muscle convulsions and hypertension combined with hyperventilation in all vertebrates. Through an analysis of the European fire salamander’s skin secretions, scientists have determined that another alkaloid, such as samandarone, is also released by the salamander. [14]
Samandarines are exclusively produced and secreted by the fire salamander through their parotoid glands (20 mg/gland). Samandarin is the main component of these glandular secretions, although the precise ratio of the alkaloids can vary from species to species and individual to individual. [5]
The pathogen, unidentified up to then, had devastated fire salamander populations in the Netherlands. Molecular phylogenetics confirmed it as related to the well known chytrid B. dendrobatidis . Like this species, it causes chytridiomycosis , which is manifested in skin lesions and is lethal for the salamanders. [ 1 ]
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
The rate at which coronavirus tests are coming back with positive results continues to climb across California. For the week ending July 1, 10.6% of coronavirus tests statewide came back positive ...
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Earlier this week, Ladders reported on recurring COVID-19 symptoms thought to be atypical by medical professionals. Initially, a persistent dry cough, fever, and labored breathing were the most ...
