We thank Emilie Donatin and Jacqueline Chevalier for help during determination of bacteriological activities.
In our study, it was clearly shown that in quarters with bacteriological cure, milk NAGase activity decreased to the threshold level by 4 weeks post-treatment (Fig. 1).
Efficacy of treatment was assessed twice by physical examination of the udder, bacteriological culturing and determination of SCC and NAGase activity in milk about 2 weeks (mean 14.9 days, min. 10 days, max. 23 days) and 4 weeks (mean 29.2 days, min. 26 days, max. 37 days) after the beginning of the treatment.
The veterinarian took an aseptic milk sample from the affected quarter(s) for bacteriological examination and N-acetyl β-D-glucosaminidase (NAGase) activity determination.
The aim of the present study was to evaluate the antifungal activity of coriander essential oil according to classical bacteriological techniques, as well as with flow cytometry.
Antibacterial activity of CdS/ZnO nanocomposites were studied using the bacteriological test-well diffusion agar method and results showed significant antibacterial activity in CdS/ZnO composite with 1 3 ratio.
Efficacy of treatments was assessed 2 and 4 weeks later by physical examination, bacteriological culture, determination of CMT, somatic cell count and NAGase activity in milk.
In this study, screening for bacterial AHLs relied on bacteriological monitor systems, which consists of a phenotypic response of β-galactosidase activity.
Taking into account test result deviations, inherent to bacteriological methods, titres within a range of 1.108 to 1.1010 pfu/ml confer retention of activity and thus stability.
Our objective was to investigate the epidemiological, clinical and bacteriological characteristics of these infections in order to reach a better orientation of prevention activities.
