Necropsies showed females and calves were most affected, likely due to toxins from bacteria like pasteurella and clostridia, which caused organ bleeding. Normally harmless, these bacteria became deadly due to weakened immune systems, possibly from a harsh winter and wet spring that facilitated bacterial spread.
