Observational analysis reveals resistance trends in bronchopneumonia pathogens, suggesting improved livestock treatments are needed.
Respiratory diseases in cattle remain the most common in livestock complexes. Testing for sensitivity to antimicrobial drugs using phenotypic methods is key in monitoring programmes for the early detection of resistance development and tracking trends in resistance development necessary for adjusting treatment and prevention measures in livestock farming. In the course of our research, we established the sensitivity of bronchopneumonia pathogens ( Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Moraxella bovoculi, Mannheimia haemolytica ) isolated from calves in livestock complexes in the Leningrad Region. The results demonstrate the insufficient effectiveness of the therapeutic measures carried out with the use of antibacterial drugs, which is associated with the resistance of a number of bronchopneumonia pathogens. Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris , and Pseudomonas aeruginosa showed phenotypic resistance to the antimicrobial drugs tested. The data obtained as a result of monitoring can be used for scientific research aimed at improving treatment and preventive measures in livestock farming.
