Impact of Carbon Dioxide Concentrations on Laboratory Sensitivity of Species Isolated from Dairy Cows

Abstract

Importance: Current spp. culture protocols lack empirical derivation concerning carbon dioxide (CO) supplementation and are primarily based on the initial cultivation of . This study indicates that the suitable range for CO supplementation is broader than what is currently recommended by the National Mastitis Council for culturing within the specified 7-10 days. No differences in bacterial growth detection rates were observed among ambient air, 5% CO, or 10% CO supplementation during the 7- and 10-day incubation intervals. These new insights provide evidence supporting the possibility of culturing spp. under ambient air conditions in a laboratory setting.
