Food is not likely a source of resistant E Coli

A large genomic medicine study by scientists in the UK has found that almost all blood infections caused by drug-resistant E. coli involve human-associated strains of the invective agent, with very little contribution from the organic phenomenon.

The study, printed in the Lancet Infectious Diseases, found that the extended-spectrum beta-lactamase-producing (ESBL) E Coli sequence kind (ST) 131 was the predominant strain found in blood isolates, also as in samples collected from human excretory product and waste product, whereas isolates from meat, veterinary diagnostic samples, and farm runoff were dominated by alternative ESBL E coli sequence sorts. Few drug-resistant E coli strains were shared among the animal and human isolates.

The writers of the study say the findings counsel that whereas ESBL E coli strains are widespread in humans, animals, and also the surroundings, there is a very little crossover between these strains, and efforts to scale back invasive ESBL E Coli infections ought to target limiting human transmission.

Comparison of resistant E coli reservoirs

The objective of the study was to look at the role of the organic phenomenon in transmission drug-resistant E coli to humans, a difficulty that’s being progressively scrutinized with the emergence of antibiotic resistance as a worldwide health threat. Whereas the connection between E coli strains that cause diarrhea and alternative enteric sickness and the food product is well established, in recent decades researchers are documenting tract infections (UTIs) caused by E Coli strains that conjointly seem to be joined to exposure to food-producing animals.
