Over the last decade, antibiotic resistance has risen in bacteria from companion animals, notably with strains like ESBL and CPE in pets like dogs.
A study assessed 44 hospitalized dogs and found that 25% were colonized by ESBL-E bacteria upon admission, increasing to 45.5% at discharge, identifying specific resistant species like E. coli and K. pneumoniae.
Factors such as prior corticosteroid use and existing health conditions were linked to higher rates of colonization, highlighting the potential risk of pets serving as reservoirs for resistant bacteria that could affect humans.
