Occurrence of antibiotic resistance in Staphylococcus spp. at dairy farms with conventional and organic system and its evaluation with GLMM

Popis výsledku v původním jazyce

The purpose of our study was to evaluate the occurrence of antibiotic resistance (ATBR) in S. aureus (SA), S. haemolyticus (SH), S. chromogenes (SC), at dairy farms in Czech Republic. Besides, we made comparison between conventional and organic production systems in dairy cattle. During statistical analysis we had to tackle with problems associated with log-transforming data and data from a field research: unbalanced data with combination of fixed (species, production system) and random (farm) effects.502 milk samples from 6 farms with organic and 40 farms with conventional production system were tested on the occurrence of three Staphyloccocus species and their resistance to 14 ATB. The mean occurrence of ATBR was lower at organic farms (0.19 per sample) than at conventional farms (0.49 per sample). The reason was because a few farms in the convention system had higher occurrence of ATBR, and moreover, the samples from these farms has been sent to the laboratory more often. This part
