Thames Water want to pollute illegally until 2040. Ofwat must say NO. Thames water want to make at deal with Ofwat, to pollute illegally for 15 years

๐ŸšจUrgent: Thames Water want permission from Ofwat to ILLEGALLY pollute rivers and seas until 2040.

๐ŸคฎThey want your bills to fill their pockets with gold, while they fill your rivers with sewage.

โœ๏ธSign now. Tell Ofwat to say NO to Thames Water before Tuesday 21st October.

Most viruses seem to get more transmissible but less virulent as a pandemic evolves, and that is true for SARS-CoV-2. Of course some folk get MORE susceptible after every infection. Itt is far from over.

Recent research has shown that human plasmacytoid dendritic cells (pDCs) have been altered by #SARSCoV2 ๐Ÿฆ This could have implications for both viral persistence and the development of #LongCOVID, with the Omicron subvariants having a more prominent effect.

Membrane proteins ClcB, PtsI and YcaM mediate the bactericidal effects of colistin in Escherichia coli Bacteria can be killed very effectively by targeting their first line of protection. The cell membranes (outer and inner membranes) of Gram-negative bacteria are directly targeted by antibiotics, such as polymyxins, via electrostatic interactions with their lipopolysaccharide (LPS) fraction. The downstream effects - preceding the cell death - of the disruptions of the bacterial membranes upon the intercalation of these antibiotics are unknown. By screening a set of E. coli membrane protein knockouts, three membrane transporters were shown to mediate the growth-inhibitory effects of colistin. This was corroborated with growth assays on gain-of-function strains, cytotoxic assays and in vivo infections in an invertebrate animal model. This is first-time evidence that the disruption caused to membrane proteins, such as the chloride channel ClcB, the sugar transport system component PtsI and the hypothetical Glutamate:GABA antiporter YcaM, is part of the cytotoxic pathway that follows or is concomitant to the electrostatic intercalations of polymyxins with the Gram-negative bacteria membrane. ### Competing Interest Statement The authors have declared no competing interest.
