Histopathological Evidence of Regeneration following Hepatotoxic Effects of the Cyanotoxin Microcystin-LR in the Hardhead Catfish and Gulf Killifish.

Journal of aquatic animal health

Fournie JW, Courtney LA.
PMID: 28880794
J Aquat Anim Health. 2002 Dec;14(4):273-280. doi: 10.1577/1548-8667(2002)014<0273:HEORFH>2.0.CO;2.

The cyanobacterial toxin microcystin-LR (MC-LR) causes liver damage in several freshwater fish species. In the present study, two estuarine species, hardhead catfish Arius felis and gulf killifish Fundulus grandis, were injected intraperitoneally with MC-LR at 45-300 μg/kg and their...

Harmful algal blooms represent a severe issue worldwide. They affect ecosystem functions and related services and goods, with consequences on human health and socio-economic activities. This study reports new data on paralytic shellfish toxins (PSTs) from Sardinia and Sicily...

Ecology and Physiology of the Pathogenic Cyanobacterium Roseofilum reptotaenium.

Life (Basel, Switzerland)

Richardson LL, Stanić D, May A, Brownell A, Gantar M, Campagna SR.

Life (Basel). 2014 Dec 15;4(4):968-87. doi: 10.3390/life4040968.

Roseofilum reptotaenium is a gliding, filamentous, phycoerythrin-rich cyanobacterium that has been found only in the horizontally migrating, pathogenic microbial mat, black band disease (BBD) on Caribbean corals. R. reptotaenium dominates the BBD mat in terms of biomass and motility,...

Long-term, low-dose exposure to microcystin toxin does not increase the risk of liver tumor development or growth in mice.

PMID: 10763244
Anal Chem. 2000 Apr 01;72(7):1490-4. doi: 10.1021/ac990974d.

A new sample injection method for foam countercurrent chromatography (CCC), named the "recycle injection system", has been developed. In this system, the effluent from the liquid outlet is directly returned into the column through the sample feed line so...

Covalent glutathione conjugation to cyanobacterial hepatotoxin microcystin LR by F344 rat cytosolic and microsomal glutathione S-transferases.

Polyclonal antibodies against microcystin-LR (MC-LR), a cyclic heptapeptide toxin, were generated in rabbits using MC-LR-BSA. An enzyme-linked immunosorbent assay (ELISA) was developed for the characterization of the antibodies and their potential use for analytical purposes. The concentration of MC-LR...
