Four types of bacteria, two fluorescent pseudomonads, one aeromonad (Aeromonas hydrophila anaerogens) and one coccus (Micrococcus varians) were isolated from skin lesions of airbreathing fishes. The bacterial culture in mixed condition induced severe ulcers in healthy Anabas testudineus. Pure cultures of each of two pseudomonads and an aeromonad separated from the mixture induced superficial ulcer formation.
An assembly of carbonyls held together by weak-bond interactions (Constitutional Dynamic Chemistry) results in bulk polarisation. Molecules participate in reactions in a cycle rather than as individual moieties leading to higher reaction rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
