Multi-drug resistant E. coli strains were found in healthy women showing no symptoms of urinary tract infections. This led researchers to reevaluate the clinical significance of bacteria in urine without symptoms and the possibility of pandemic strains.
Researchers have identified a cluster of four patients harboring Escherichia coli carrying a rare antibiotic resistance gene, mcr-1. That gene renders the microbe resistant to colistin, an antibiotic of last resort. Three of those patients showed no symptoms, raising the risk of spread.
Since March 2, 72 people have gotten sick, eight of whom have been hospitalized (though there could be more, since the CDC only has that data on 47 people). Nearly half of those infections are in Kentucky. Tennessee and Georgia are sharing some of the burden and a few cases have popped up in Ohio and Virginia.
Thirty-two people have been sickened and 13 hospitalized because of contaminated food likely linked to romaine lettuce, the US Food and Drug Administration (FDA) said.
Electrical engineers have adapted a molecular electronic device called a single-molecule break junction to detect RNA from strains of E. coli known for causing illness.
Technique may also apply to salmonella and production of a single bacteria for immunizing poultry against several salmonella serogroups.
Officials are turning their efforts to investigating how lettuce grown on several farms within the same growing region could all become contaminated at the same time.
The US Centers for Disease Control and Prevention (CDC) has now confirmed 197 cases in 35 states and five deaths in this outbreak.
Canadian health officials are reporting six illnesses of E. coli O157 with a similar genetic fingerprint to illnesses reported in the US.
Though scientists have zeroed in on Yuma, Arizona, as the source of ongoing multi-state outbreak of E. coli, they’re still not sure what actually caused the initial contamination and how it actually occurred.
