Key result
The newly emerging FMDV serotype A strain caused higher peracute mortality in buffalo calves (25.7%; 95% CI: 13-43) than in cattle calves (8.6%; 95% CI: 2-24).
Why the study?
A severe foot-and-mouth disease epidemic caused significant animal losses even in vaccinated farms, motivating investigation into the newly emerging strain and its effect on buffalo and cattle calves.
Population
70 cattle and buffalo calves in a single infected farm in Beheira province
Comparison

A newly emerging FMDV serotype A strain in Egypt causes more severe disease and higher mortality in buffalo calves compared to cattle calves.
Metwally et al. (2023) conducted an observational in Foot-and-mouth disease (n=70). FMDV serotype A infection in buffalo calves vs. FMDV serotype A infection in cattle calves was evaluated on Peracute mortalities. The newly emerging FMDV serotype A strain caused higher peracute mortality in buffalo calves (25.7%; 95% CI: 13-43) than in cattle calves (8.6%; 95% CI: 2-24).
