A microbiological and molecular study of campylobacter and related species isolated from ostriches (Struthio camelus)
… filtration onto antibiotic-free Tryptose blood agar plates, and incubation at 37 ºC in a hydrogen-enhanced microaerobic atmosphere (Lastovica, 2006). The isolates were identified as C. jejuni subsp. jejuni. The multiplex PCR of Neubauer and Hess (2006) was applied to some of these …

Effectiveness of GentleWave CleanFlow on Multispecies Endodontic Biofilm Removal in Single Rooted Extracted Teeth
… treatment, canals were swabbed and plated on blood agar plates and incubated for 48 hours when colony forming units were counted. Results: Both GW and standard needle irrigation demonstrated significantly lower CFU/mL than the negative control (p<0.001). However, the GW and positive control …

Efficiency of the TargeTron Gene Knockout System as a Transformative Protocol for the Mutagenesis of Listeria monocytogenes
… to 1250V. Following shock, cells were grown in blood agar or brain heart infusion media containing kanamycin. Pores were induced in the cell wall prior to electroporation by incubating the bacteria in media containing pencillin, ampicillin, or lysozyme. Results show no colonies on selective …

Effectiveness of on-farm screening tests for detection of antibiotic residues and control of mastitis through antibiotic therapy based on somatic cell counts
… first time during that lactation was culture on blood agar plates to detect mastitis pathogens, and the SCC was determined. Experimental group cows were treated in those quarters with a SCC ≥ 5 while control cows had antibiotic therapy administered based only on clinical symptoms. Treatment group …
