Add Tag | Summary: | Equine enterocolitis is a significant pathology in equine production, with an etiology involving various enterobacteria that can cause similar clinical signs and symptoms. In areas and/or facilities with a high concentration of horses, outbreaks are more likely to occur, leading to high morbidity and mortality rates, as well as zoonotic transmission to personnel involved in care, management and treatment. This research aimed to evaluate the presence of enterobacteria at the Ecuadorian Army Remount Center through the coproculture method applied to the entire equine population, assess antibiotic sensitivity, and identify related risk factors. Two main bacteria were identified: Escherichia coli in 3.6% of the horses and Enterobacter aerogenes and Escherichia coli in 1.8%. When analyzing antimicrobial resistance, both bacteria showed 100% sensitivity to amikacin, enrofloxacin, ceftriaxone and tetracycline. However, Escherichia coli exhibited 33,33% resistance to ampicillin, sulfamethoxazole- trimethoprim and amoxicillin-clavulanic-acid. Chi-square tables revealed a statistical relationship between the detected enterobacteria and age, with foals and elderly horses being more affected due the immunological factor. Additionally, a potential correlation was found between mixed feeding practices, the presence of vectors and mature disposal. These finding highlight the need to strengthen prevention and control measure in such facilities. Furthermore, the rational use is crucial to prevent the rise of antimicrobial, resistance in these strains, which is a increasing public health concern. |
