One year after a mysterious epidemic wiped out 12,000 critically endangered saiga antelopes (Saiga tatarica) in Kazakhstan, the ailment has struck again there, this time killing more than 400 animals.
Kazakhstan Today reports that 442 saiga antelopes—including 360 does and 82 calves—were found dead in May. Like a year ago, they fell victim to pasteurellosis, an infection that afflicts the lungs.
