Veterinary Clinics of North America: Food Animal Practice, 2020 Diverse groups of ectoparasitic arthropods cause significant morbidity and mortality in most of the approximately 1.49 billion head of cattle worldwide. Hematophagous ectoparasites (ie, blood-feeding flies, myiasis-causing flies, lice, mites, ticks) are the most important in cattle.

Cohorts of immature Pteropus bats show interannual variation in Hendra virus serology
Journal of Animal Ecology, EarlyView.Pteropus bat with offspring, photo taken by Manuel Ruiz‐Aravena. Abstract Understanding the drivers of seasonal disease outbreaks remains a fundamental challenge in disease ecology. Periodic outbreaks can be driven by several seasonally varying factors, including pulses of susceptible individuals through births, changes in host behaviour and social ...
