Diarrhoeagenic (DEC) pathotypes are defined by genes located on mobile genetic elements, and more than one definitive pathogenicity gene may be present in the same strain. In August 2022, UK Health Security Agency (UKHSA) surveillance systems detected an outbreak of hybrid Shiga toxin-producing /enterotoxigenic (STEC-ETEC) serotype O101:H33 harbouring both Shiga toxin () and heat-stable toxin (). These hybrid strains of DEC are a public health concern, as they are often associated with enhanced pathogenicity.

Plants respond to attacks by insects by releasing herbivore-induced plant volatiles (HIPVs), which are known to influence the behavior of natural enemies, conspecific and heterospecific insects. However, little is known about how HIPVs induced by one insect species influence the behavior of an allospecific insect species, particularly if these insects belong to different feeding guilds. Here, using the interaction of two co-occurring insects with different feeding guilds - Bemisia tabaci (a sap sucking insect) and Tuta absoluta (a leaf mining insect) - on potato plants, we report that T.

Background: Lately, significant attention has been drawn towards the potential efficacy of cholera toxin (CT)-an exotoxin produced by the small intestine pathogenic bacterium Vibrio cholera-in modulating cancer-promoting events. In a recent study, we demonstrated that early-life oral administration of non-pathogenic doses of CT in mice suppressed chemically-induced carcinogenesis in tissues distantly located from the gut. In the mammary gland, CT pretreatment was shown to reduce tumor multiplicity, increase apoptosis and alter the expression of several cancer-related molecules.

Chemical industries are highly vulnerable to accidental events or terrorist attacks due to their processing, storage, and transportation of explosive, flammable, and toxic materials. Major industrial risks include fire, explosion, and toxic chemical release. An effective risk evaluation system is essential to prevent accidents or terrorist attacks.

Drought has an effect on hydrologic conditions and water quality under climate change. Small water retention in forests is one of the priority investment programs implemented in recent years, supported by the European Union. This study aimed to assess the ecological conditions of forest lakes using macrophytes and benthos organisms diversity as an ecological indicator of ecosystem conditions under climatic changes.
