The Use of Kaolin as a Prophylactic Treatment to Prevent Columnaris Disease (Flavobacterium covae) in Commercial Baitfish and Sportfish Species [PDF]

Veterinary Sciences, 2023
Aquaculture farms in Arkansas, USA routinely battle columnaris disease caused by Flavobacterium covae. Columnaris is prevalent during stressful events such as feed training and when fish are stocked at high densities in holding vats before sale.

Metabarcoding Reveals a Potentially Undescribed Columnaris-Causing Bacterium in Peracute Skin Disease of Rainbow Trout (Oncorhynchus mykiss, Walbaum). [PDF]

J Fish Dis
ABSTRACT Columnaris‐causing bacteria (CCB) represent a group of four Flavobacterium species, previously classified under Flavobacterium columnaris, causing a threatening condition in salmonid farming characterised by cutaneous and gill lesions, commonly referred to as ‘saddleback disease’. A peracute skin disease outbreak with high mortality in rainbow

A two‐photon fluorescence micro‐spectroscopy method for chemotaxonomic characterization of fossil resins [PDF]

Appl Plant Sci
Abstract Premise Amber, a fossilized chemical defensive exudate, is important for understanding ancient plant–insect/pathogen interactions, yet its botanical origins, especially for Cretaceous amber, remain enigmatic. Here, we develop and apply a fluorescence micro‐spectroscopy approach within the context of a larger study on the provenance of amber ...
