Investigation of the resistance of bacterial pathogens of gastrointestinal and respiratory diseases of piglets to antimicrobial drugs

The level of resistance of E. coli, S. cholerae suis, S. typhimurium, Str. pneumoniae, and P. multocida microorganisms to ampicillin, oxytetracycline, gentamicin, cefazolin, ciprofloxacin, levomycetin, and nitrofurans and the dynamics of its development over the years are given. The majority of cultures were resistant to six drugs. Ciprofloxacin, to which the majority of tested pathogens are highly sensitive, is recommended for treating animals.
