Nocardia cyriacigeorgica in a Mallard (Anas platyrhynchos) from Arizona, USA Open
Nocardia spp. are opportunistic pathogens of humans, domestic animals, and wildlife that can cause high levels of morbidity and mortality. Here, we present a unique case of nocardial airsacculitis in a free-ranging mallard (Anas platyrhync…
