Avaliação físico-química e microbiológica das soluções desinfetantes de sulfato de cobre a 5% e cloridrato de polihexametileno biguanida a 1% em pedilúvio para bovinos

Abstract

The purpose of this study was evaluate the physical-chemistries aspects and microbiology of footbathing in 5% copper sulphate and 1% polihexametilen biguanide associated to surgical procedures and parenteral antibiotics to treatment of bovine digital lesions. The analyses physical-chemistries consisted of the determination of the pH and of the concentration of chloridrate polihei<ametilen biguanide (P.H.M.B.) and copper. The analyses accomplished microbiology were the count of microorganism mesophilic aerobics or facultative and mesophilic anaerobics. The obtained results demonstrated that the physical-chemistries characteristics of both. solution maintained stable and 1% polihexametilen biguanide solution showed lower count of microorganism mesophilic · aerobics o r facultativa and mesophilic anaerobics than 5% copper sulphate solution.
