Intramammary dry-off treatment is widely considered an effective method for preventing and curing intramammary infection (IMI) in lactating cows; however, it is not commonly used in small ruminants like goats. Therefore, this study was designed to evaluate the effect of an approved cefazolin-based intramammary treatment on the milk microbiota of Alpine dairy goats during the dry and early lactation periods. Sixty goats were randomly selected based on bacteriological results and randomly allocated into the control group (CG) or the treatment group (TG).

As most human infections are caused by serogroup 1 (Lp1), a reliable method for Lp distinction can be crucial for bacterial spread prevention. As the ability to withstand in environments and to cause the waterborne disease is strongly related to specific genes, the identification of virulent strains can be of great relevance to implement water environmental monitoring and to contain harmful outbreaks to public health.

- Different types of bedding materials in dairy farms include organic options like recycled manure solids (RMS) and new sand (NS), which require microbiological analysis to ensure animal health.
- The study examined how refrigeration and freezing affect the total bacterial count (TBC) and specific microbial classes in various bedding substrates, revealing that fresh samples showed higher TBC compared to refrigerated or frozen ones.
- Overall, freezing typically resulted in lower counts of Gram-negative bacteria and E. coli compared to refrigeration, but did not significantly impact the count of streptococci and similar organisms across all bedding materials.
Article Synopsis
- Conventional bacterial diagnostics for dairy cows often rely on culture techniques, but these methods lack empirical support and primarily follow outdated guidelines from the National Mastitis Council.
- The study investigated how different concentrations of carbon dioxide (CO) affect the growth of bacterial isolates, showing that while CO enhances growth detection in the early days of incubation, by day 10, all conditions yielded similar growth results.
- Findings suggest that expanding the accepted range for CO concentrations during bacterial cultures could improve efficiency, and that the recommended protocols may need to be updated to reflect the absence of CO's critical role in longer incubations.
