Hypothesis

What is the prevalence of bovine tuberculosis (BTB) in cattle and what are the risk factors for infection in human and cattle populations in Torodi?

Conclusion

The study confirmed that BTB is endemic in cattle in Torodi and the risk of transmission to humans is potentially high.

Supporting Evidence

  • The overall apparent individual animal prevalence of tuberculin reactors was 3.6%.
  • The only household level risk factor that significantly influenced the presence of BTB in cattle was the presence of animals coughing in the herd.
  • Households with the presence of cattle coughing had higher odds of BTB infection.
  • Consumption of unpasteurized milk is common among the population.

Takeaway

This study found that many cows in a rural area of Niger have a disease called bovine tuberculosis, which can also make people sick.

Methodology

A survey was conducted with 51 households and 393 cattle were tested using the Comparative Intradermal Tuberculin Test.

Potential Biases

Potential biases in household reporting and selection of participants.

Limitations

The study was based on a sample design which limits the generalizability of the results.

Participant Demographics

Households primarily from the Fulani ethnic group, with a majority of heads being illiterate.
