CHARACTERISTICS OF A MYXOBACTERIUM, CHONDROCOCCUS COLUMNARIS, ISOLATED FROM DISEASED LOACHES

NIPPON SUISAN GAKKAISHI, 1966
A Chondrococcus-like bacterium of high virulence was isolated from diseased loaches (Misgurnus anguillicaudatus). The basal medium used in this study as the standard for various purposes contains 0.3 per cent Bacto-tryptone and 0.2 per cent yeast extract, adjusted to pH 7.5 (TY broth).

Outside-host growth of pathogens attenuates epidemiological outbreaks. [PDF]

PLoS ONE, 2012
Opportunist saprotrophic pathogens differ from obligatory pathogens due to their capability in host-independent growth in environmental reservoirs. Thus, the outside-host environment potentially influences host-pathogen dynamics.

A Two‐Step PCR Workflow Reveals Predominance of Flavobacterium covae in Ornamental Fish With Clinical Signs of Columnaris Disease

Journal of Fish Diseases, EarlyView.
ABSTRACT Columnaris is an important bacterial disease of freshwater fish and is increasingly recognised as being caused by a species complex historically referred to as Flavobacterium columnare. A two‐step molecular workflow was applied to ornamental fish with clinical signs of columnaris disease from a multispecies commercial distributor operating a ...

Treatment of Trichodina sp reduced load of Flavobacterium columnare and improved survival of hybrid tilapia

Aquaculture Reports, 2015
Bacterium Flavobacterium columnare and protozoan Trichodina spp are common pathogens of cultured fish. Studies of parasite–bacterium interaction show evidence that concurrent infections increase severity of some infectious diseases, especially bacterial ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

A Review of Molecular Responses of Catfish to Bacterial Diseases and Abiotic Stresses

Frontiers in Physiology, 2018
Catfish is one of the major aquaculture species in the United States. However, the catfish industry is threatened by several bacterial diseases such as enteric septicemia of catfish (ESC), columnaris disease and Aeromonas disease, as well as by abiotic ...
