Antibiotic resistance of microorganisms isolated from a Baikal seal

Abstract

The article presents the results of microbiological studies of the material taken from the seals’ corpses. The authors studied the taxonomic characteristics of microorganisms, their virulence and antibiotic resistance. It has been established that the following types of microorganisms are found in the seal: Citrobacter braakii, S. warneri, S. aureus, Escherichia coli serotypes O2, O18 and O39, Lactobacillus sakei, Aguamicrobium lusatiense. All pathogens isolated from the gastrointestinal tract were sensitive to 52.6% of antibiotics (ampicillin, cefuroxime, cefixime, gentamicin, amikacin, ciprofloxacin, ofloxacin, furadonin, Ceftriaxone) and resistant to 15.8% of antibiotics, two representatives of cephalosporins (cefaclor and ceftazidim) and ticarcillin. Conditionally pathogenic enterobacteria (Citrobacter braakii and Escherichia coli) isolated from muscles and liver were sensitive to all antibiotics.

“…Следует отметить, что в последнее время метод идентификации по белковым профилям микроорганизмов или прямое белковое профилирование все чаще применяется наряду с классическими и молекулярно-генетическими методами идентификации различных микроорганизмов [5,6]. Данный метод отличается быстротой проведения [7], высокой производительностью [8] и более низкой себестоимостью анализа [9] [11,12,13].…”
