E.coli BlogShiga_toxin_(Stx)_PDB_1r4q

Cloud’s Meats, Inc. is voluntarily recalling beef and pork products possibly contaminated with E. coli. following positive test results for non-0157 Shiga toxin-producing E. coli (STECs) in samples of items produced mid-November. The samples were taken during routine testing conducted by the Missouri Department of Agriculture’s Meat and Poultry Inspection Program November 14 and analyzed by the Department’s Veterinary Diagnostic Laboratory in Springfield.

Research – Bacterial Adaptation to Cold

Microbiology

Micro-organisms react to a rapid temperature downshift by triggering a physiological response to ensure survival in unfavourable conditions. Adaptation includes changes in membrane composition and in the translation and transcription machineries. The  cold shock response leads to a growth block and overall repression of translation; however, there is the induction of a set of specific proteins that help to tune cell metabolism and readjust it to the new conditions. For a mesophile like E. coli, the adaptation process takes about 4 h. Although the bacterial cold shock response was discovered over two decades ago we  are still far from understanding this process. In this review, we aim to describe current knowledge, focusing on the functions of RNA-interacting proteins and RNases involved in cold shock adaptation.

Research – Campylobacter Chromosomes Mapped

Food Poisoning BulletinCampylobacter

New research from the Institute of Food Research has mapped chromosomes of Campylobacter. Scientists are trying to understand how this pathogenic bacteria controls its genes to develop new strategies to fight it. In the UK, Campylobacter is the most common cause of foodborne diarrheal illness.

The chromosome map shows where all of the bacteria turns on its genes. Those are called transcriptional start sites (TSS).  The bacteria turns on different genes in response to changes in its environment. TSS are also how the bacteria evolved to adapt to new situations. All organisms have these control mechanisms.
