Anthrax (Bacillus anthracis) |
answer
Inhaled spores, engulfed but not killead by phagocytes. Respiratory distress, necrosis of small vessels and bleeding from orifices. Sudden death. |
question
Botulism (Clostridium botulinum) |
answer
Ingest toxin, absorbed through GI, binds NM junction, flaccid paralysis. |
question
Tetanus (Clostridium tetani) |
answer
Spores enter through wounds, diffuse via vessels to NM, blocks inhibitory neurons, causes tremors, stiffness, high fever. |
question
Overeating disease (enterotoxemia)/pulpy kidney disease (Clostridium perfringens) |
answer
Ingest spores, germinate in GI, overeating of grain allows bacteria to grow and make tons of toxin, toxin causes ulceration and hemorrhage, bloody diarrhea, sudden death. |
question
Malignant edema (Clostridium septicum) |
answer
Spores enter wound, germinate, make lots of toxins, causes tissue necrosis and rapidly fatal wound infection. |
question
Braxy (Clostridium septicum) |
answer
Abomasum gets inoculated by rough feed (sheep), toxin causes necrosis of tissue and inflammation of abomasum. |
question
Blackleg (Clostridium chauveoi) |
answer
Ingest spores, germinate in GI, seed to tissues, when tissues get damaged and become anaerobic, bacteria proliferate and cause massive muscle swellings, edema and hemorrhage. Hi fever, kills quickly. |
question
Big head (Clostridium novyi type A) |
answer
Rams get penetrating head wounds from fighting, spores get in and germinate, make lots of gas and cause tissue destruction. Often causes death. |
question
Black disease (Clostridium novyi type B) |
answer
Spores ingested and seed liver, fluke migration causes optimal environment for spore germination, toxin goes systemic, causes major hemorrhage under skin (black lesions). |
question

answer
Ingest spores, seed blood stream and tissue through lymphatics, toxin causes major intravascular hemolysis, hemoglobinuria, abnormal feces, fever, death. |
