Cerebrospinal elaphostrongylosis (CSE) is caused by a nematode Elaphostrongylus rangiferi. The lifecycle of the parasite requires an intermediate host. This disease was introduced to Canadian caribou by reindeer from Norway. The most likely means of introduction was: Infected reindeer entered Canada and shed the parasite in their feces, local snails ingested the parasite, and were then ingested by the Canadian caribou. Infected reindeer entered Canada and flies mechanically transmitted the parasite from the reindeer to the Canadian caribou. Infected reindeer transmitted the disease via nose to nose contact with the native Canadian caribou. Contaminated boots on herdsmen from Norway allowed Canadian caribou to sniff and lick their boots.

One of your clients who recently returned from a mission trip to The Democratic Republic of the Congo calls because he is concerned about some of his pigs that are slightly lame, and he thinks at least one of them has sores on its snout. He also has other animals, i.e. two dogs, farm cats, a couple of horses, goats, and sheep. What should you do: Examine the sick pigs only Look over all of the healthy animals on the farm first then proceed to the animals showing clinical signs Advise the owner to give antibiotics to the sick pigs. Immediately contact state and federal authorities and not attempt to examine any animals yourself since this sounds like it could be FMD. Ask him to watch them for a day or two and see if they get better.

Anthrax in cattle: Is most commonly diagnosed in cattle on pasture in the southeastern U.S., sudden death may occur in some animals, others will often present with acute lameness, depression, and characteristic edematous and crepitant swelling in the hip and shoulder. Is rare because cattle are fairly resistant; however, peracute disease (sudden death) can result after exposure to large doses of anthrax. Most commonly presents as a peracute disease (sudden death) after ingestion or inhalation of spores; bloody discharges from the body orifices from the dead animals result in contamination of the environment with spores and these are a source of infection to other animals and people. Most commonly presents as cutaneous lesions; these lesions can be difficult to detect and the disease then progresses to septicemia and sudden death. Affects usually the adult cattle in good condition; they often have hemoglobinuria (blood in the urine) a couple of days before they die.
