Quality loss assessment in fish-based ready-to-eat foods during refrigerated storage
Grasas y Aceites, 2013 The present research addresses the quality loss in two different ready-to-eat (RTE) seafoods. With this aim, chemical and microbiological parameters were measured in tuna lasagne (TL) and hake roe foods which were refrigerated (4°C) for up to 35 and 71 ...

The Toxins of Cyanobacteria [PDF]
Acta Medica (Hradec Kralove, Czech Republic), 2001 Cyanobacteria, formerly called ”blue-green algae“, are simple, primitive photosynthetic microorganism wide occurrence in fresh, brackish and salt waters. Forty different genera ofCyanobacteriaare known and many of them are producers of potent toxins responsible for a wide array of human illnesses, aquatic mammal and bird morbidity and mortality, and ...

CsrA and its regulators control the time-point of ColicinE2 release in Escherichia coli [PDF]
Scientific Reports 8, 6537 (2018), 2018 The bacterial SOS response is a cellular reaction to DNA damage, that, among other actions, triggers the expression of colicin - toxic bacteriocins in Escherichia coli that are released to kill close relatives competing for resources. However, it is largely unknown, how the complex network regulating toxin expression controls the time-point of toxin ...

Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins
Toxins, 2018 Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins).

Environmental toxicity influences disease spread in consumer population [PDF]
arXiv, 2022 The study of infectious disease has been of interest to ecologists since long. The initiation of epidemic and the long term disease dynamics are largely influenced by the nature of the underlying consumer (host)-resource dynamics. Ecological traits of such systems may be often modulated by toxins released in the environment due to ongoing anthropogenic

Mechanisms of Action and Cell Death Associated with Clostridium perfringens Toxins
Toxins, 2018 Clostridium perfringens uses its large arsenal of protein toxins to produce histotoxic, neurologic and intestinal infections in humans and animals. The major toxins involved in diseases are alpha (CPA), beta (CPB), epsilon (ETX), iota (ITX), enterotoxin (

Modeling sRNA-regulated Plasmid Maintenance [PDF]
, 2016 We study a theoretical model for the toxin-antitoxin (hok/sok) mechanism for plasmid maintenance in bacteria. Toxin-antitoxin systems enforce the maintenance of a plasmid through post-segregational killing of cells that have lost the plasmid. Key to their function is the tight regulation of expression of a protein toxin by an sRNA antitoxin.

Chemical warfare and survival strategies in bacterial range expansions [PDF]
J. R. Soc. Interface 11, 20140172 (2014), 2014 Dispersal of species is a fundamental ecological process in the evolution and maintenance of biodiversity. Limited control over ecological parameters has hindered progress in understanding of what enables species to colonise new area, as well as the importance of inter-species interactions.

The role of toxins in Clostridium difficile infection.
FEMS Microbiology Reviews, 2017 Clostridium difficile is a bacterial pathogen that is the leading cause of nosocomial antibiotic-associated diarrhea and pseudomembranous colitis worldwide. The incidence, severity, mortality and healthcare costs associated with C.

ATR Kinase Is a Crucial Player Mediating the DNA Damage Response in Trypanosoma brucei
Frontiers in Cell and Developmental Biology, 2020 DNA double-strand breaks (DSBs) are among the most deleterious lesions that threaten genome integrity. To address DSBs, eukaryotic cells of model organisms have evolved a complex network of cellular pathways that are able to detect DNA damage, activate a
