Symptoms of botulism?

summary

Botulinum is a kind of anaerobic bacteria. It can decompose glucose, maltose and fructose in gastrointestinal tract, produce acid and gas, and digest and decompose meat dregs to make them black and putrid. In anaerobic environment, this bacterium can secrete strong botulinum toxin, which can cause special neurotoxic symptoms, with high morbidity and mortality. Botulinum is widely distributed in nature. It is often detected in soil and occasionally in animal feces. Symptoms of botulism? Let's talk about it

Symptoms of botulism?

The onset of the disease was sudden. At the beginning of the disease, there were headache, dizziness, dizziness, fatigue, nausea and vomiting (type E bacteria had more nausea and vomiting, while type a bacteria and type B bacteria had less nausea and vomiting); Later, the internal and external muscles of the eye paralysis, eye symptoms, such as blurred vision, diplopia, blepharoptosis, mydriasis, light reflex disappeared.

Mild cases gradually recovered within 5-9 days, but the general fatigue and ophthalmoplegia lasted for a long time. The mortality rate was 30-60%. The main causes of death were respiratory failure caused by bulbar paralysis, secondary infection caused by cardiac insufficiency and aspiration pneumonia.
