content: Includes a 1940 handwritten note from Texas rancher, Kassel Moseley, asking for a "gun and the medicine for the shot." Moseley refers to blackleg vaccine (clostridium chauvoei infection) which occurs commonly in beef cattle, but also in dairy cattle and sheep. Clostridium chauvoei is a spore-forming, gram-positive anaerobic bacillus. Its spores are ubiquitous in the soil and manure, and after ingestion they are capable of crossing the intestinal mucosa, entering the bloodstream, and being carried to skeletal muscles. The most common presentation is acute
death.
