There have been many recent reports of deer found dead throughout Missouri; many of these deer have been reported to have died from bluetongue, but in all likelihood, most of these animals were infected with a disease known as epizootic hemorrhagic disease, or EHD.

While driving cross country in between calls I have noticed from the road a few cattle beginning to show evidence of lice infestation. Cattle, horses, sheep, goats and swine are all susceptible to parasitism from lice. Interestingly enough, lice are species specific meaning that there is a particular species of louse that prefers feeding on a specific species of livestock. Furthermore, in each species of livestock there are two types of lice that may be observed. Biting lice feed on dead skin cells and other debris from the surface of the skin. Sucking lice feed off of the blood. All species and types of lice cause skin irritation and in rare instances sucking lice may cause significant anemia.
