Characterization of an OrtT-like toxin of Salmonella enterica serovar Houten
(Springer, 2019-07-01)
The Escherichia coli GhoT/GhoS system is a type V toxin-antitoxin system in which the antitoxin GhoS cleaves the GhoT mRNA, controlling its translation. GhoT is a small hydrophobic protein that damages bacterial membranes. ...
Accumulation of paralytic shellfish poisoning toxins in the bivalve Aulacomya ater and two carnivorous gastropods concholepas concholepas and Argobuccinum ranelliformes during an Alexandrium catenella bloom in Southern Chile
(1998)
In the early fall of 1996, a bloom of the toxic dinoflagellate Alexandrium catenella occurred in a fjord in the southern part of Chile that resulted in very high levels of paralytic shellfish poisoning (PSP) toxicity (up ...
Variations in Growth and Toxicity in Gymnodinium Catenatum Graham from the Gulf of California Under Different Ratios of Nitrogen and Phosphorus
(Ciencias Marinas, 2012-01-01)
A strain of Gymnodinium catenatum Graham (GCCV-7), isolated from the Gulf of California, was submitted to conditions with different nitrogen-to-phosphorus ratios (5.4, 9.2, 23.5, 44.7, and 74.3) to determine the effect of ...
Virulence profile comparison between LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle and humans
(Elsevier Science, 2010-07)
For comparison purposes, the prevalence of 8 virulence markers was investigated, by PCR, in 153 cattle and 47 human Locus for Enterocyte Effacement (LEE)-negative Shiga toxin-producing Escherichia coli (STEC) strains ...
Winter distribution of toxic, potentially toxic phytoplankton, and shellfish toxins in fjords and channels of the Aysén region, Chile
(Pontificia Universidad Católica de Valparaíso, 2018)
Impact of Nitrogen Sources on Gene Expression and Toxin Production in the Diazotroph Cylindrospermopsis raciborskii CS-505 and Non-Diazotroph Raphidiopsis brookii D9
(MDPI AG, 2014)
Different environmental nitrogen sources play selective roles in the development of cyanobacterial blooms and noxious effects are often exacerbated when toxic cyanobacteria are dominant. Cylindrospermopsis raciborskii ...
Search for diarrheagenic Escherichia coli in raw kibbe samples reveals the presence of Shiga toxin-producing strains
(2016-05-01)
The aim of this study was to investigate the occurrence of diarrheagenic Escherichia coli (DEC) strains in raw kibbe samples. For this purpose, 70 samples of raw kibbe were collected from retail establishments and analyzed. ...
