where Anoplocephala perfoliata (equine tapeworm) tend to congregate
eggs pass thru feces, ate by oribatid mite, transmitted by ingestion of the oribatid mite, treated with equimax
female worms crawl out of the horse's rectum, deposit eggs on the perianal region, and crawl back into the rectum, transmitted by ingestion of eggs, treated with strongid
eggs pass thru feces, transmitted by the ingestion of eggs, treated with strongid (& regular internal parasite control program)(eggs are viable for up to 10yrs)(aka ascarid)
eggs pass thru feces, develop into larvae in the feces (lives up to 3 months), transmitted by ingestion of the larvae (which may attach to grass blades), treated with strongid (& regular internal parasite control program)(aka bloodworm)

transmitted by insects, causative agent Ehrlichia risticii, treated with oxytetracycline and IV fluids (causes acute diarrhea) (aka Equine ehrlichial colitis, Equine monocytic ehrlichiosis, Ditch fever, Shasta River crud)(mortality 30%)
toxemia caused by a specific neurotoxin produced a bacteria (Clostridium tetani) in necrotic tissue, treated with antitoxin (aka lockjaw)
septicemia (blood poisoning) caused by the sporeforming bacterium (Bacillus anthracis), vaccine available, treatment usually not possible due to acute nature but is sensitive to pencillin, streptomycin & tetracyclines)
