Clostridium Botulinum :  Gram + anaerobic rods, spore formation on exposure to oxygen, undercooked meal, blocks presynaptic terminal’s.

🔴 Neurotoxin : 8 toxins A to G  with 2 types of C1, C2. A is most toxic. 

🔴 Common human disease caused by A,B, E. Rarely F

🔴 once gets into the bloodstream it goes to block the presynaptic terminal of the neuromuscular muscular junction of voluntary motor and autonomic nervous system. 

🔴 symptoms start after 12 to 72 hours of ingestion of contaminated food

🔴 constipation / urinary retention could be due to autonomic nervous system involvement

🔴 avoid magnesium and aminoglycosides

🔴 recovery may take months or even years. 

🔴 S/S : Afebrile, Alert, normal HR & BP, may be bradycardia, lsymmetric motor weakness / flacid paralysis, no sensory deficit, fixed pupils dilated, diplopia, dysarthria, dysphagia, dyspnea, floppy infant syndrom < 1 yr.

Exceptions: secondary fever in infected wound w 10 days incubation period. Food born : incubation 10-36 hrs, nausea, vomiting, diarrhea. Heroin user: black tar Heroin is contaminated.

🔴 Repetitive nerve stimulation at 2 to 5 Hz causes decremental response (reduced > 10% amplitude)

🔴 Heat > 85°C for 5 min will decontaminate

🔴 avoid honey as it contain spores in children < 1 yr

⭕️ Toxin in serum, gastric content, stool, vomit & Food.

✅ Rx: Gastric lavage within hours

🔸Avoid home made canned food / bulging cans/ bad smelling food

♦️Nutritional support / respiratory support

♦️No Magnesium

🔹Antibiotics for wound infection: penicillin and or Metronidazole

♦️Debridement of micro-abscesses

🔸Physical therapy

🔸Occupational therapy

🔸Speech therapy

♦️Dietary eval and rx

👉🏿Talk to CDC

  1. * descending paralysis
    *black tart heroin is contaminated w spores
    *Micro abscesses in Heroin users should be cleaned and debride and washed
    *food should be warmed 85 deg C = 185 degrees F for > 5 to 10 minutes
