Hypothesis
Does concurrent infection with BVDV affect the shedding patterns of Mycobacterium bovis in calves?
Conclusion
There is no statistically significant difference in the shedding patterns of calves infected with Mycobacterium bovis alone compared to those co-infected with BVDV.
Supporting Evidence
- Calves were divided into two groups: one infected with Mycobacterium bovis alone and the other co-infected with BVDV.
- Shedding patterns were analyzed using statistical models to account for variability.
- No significant increase in mean CFU shedding was found in the BVDV-infected group.
Takeaway
The study looked at how sick calves release bacteria into the air and found that being sick with two germs at once doesn't change how much bacteria they release.
Methodology
The study involved 12 calves, half infected with Mycobacterium bovis alone and half co-infected with BVDV, with bacterial shedding measured over time.
Limitations
The power for detecting a significant BVDV effect was low due to high variability in CFU shedding.
Participant Demographics
Friesian cross calves from a farm free of BTB for over 10 years.
