Abstract

The subject of this paper is to test antimicrobials activities by medicinal plants extracts against more important contagious bovine mastitis pathogens. Disinfectants solutions was made from Baccharis trimera (Less) D.C., Compositae (Asteracea), Eucalyptus spp Labill., Myrtaceae e Tagetes minuta (Linn.), Compositae (Asteracea) plants by hidroalcoholic extraction (EHA) or decoction (DEC). S. aureus, S. agalactiae, and P. aeruginosa were used. To test for in vitro efficacy, each solution disinfectant was mixed with bacterial suspension containing 105 CFU.mL-1, by 30 seconds, two, 10 ant 30 minutes, with and without 20% of integral milk. Viable bacteria were evaluated by directed plating of neutralized aliquots. The worked included chlorhexidine 0,18% by control and it was executed in duplicate. EHA Eucalytpus spp and EHA T. minuta were as effective as control chlorhexidine against S. aureus. This solutions plus EHA B. trimera, were as effective as control against S. agalactiae. DEC Eucalyptus and DEC B. trimera also inactivated S. agalactiae in more prolongated time. Chlorhexidine was the best against P. multocida in milk absence, although the EHA were effective at ten or thirty minutes. All solutions, inclusive control, it was sensibility to organic load. The observations from the in vitro studies presented here need to be substantiated by in vivo studies by to confirm the potentiality use of plants medicinal extracts as disinfectants/antisepsis in livestock health.
