Infant botulism is a potentially life-threatening disease caused by a bacterium called Clostridium botulinum. It grows inside a baby's gastrointestinal tract.
Clostridium botulinum is a spore-forming organism that is common in nature. The spores may be found in soil and certain foods (such as honey and some corn syrups).
Infant botulism occurs mostly in young infants between 6 weeks and 6 months of age. It may occur as early as early as 6 days and as late as 1 year.
Risk factors include swallowing honey as a baby, being around contaminated soil, and having less than one stool per day for a period greater than 2 months.
Symptoms may include:
The health care provider will do a physical exam. This may show a decreased muscle tone, a missing or decreased gag reflex, missing or decreased deep tendon reflexes, and eyelid drooping.
A stool sample from the baby may be checked for the botulinum toxin or bacteria.
Electromyography (EMG) can be done to help tell the difference between muscle and neurological problems.
Botulism immune globulin is the main treatment for this condition. Infants that get this treatment have shorter hospital stays and milder illness.
Any infant with botulism must receive supportive care during their recovery. This includes:
If breathing problems develop, breathing support, including the use of a breathing machine, may be needed.
Antibiotics do not appear to help the baby improve any faster. Therefore, they are not needed unless another bacterial infection such as pneumonia develops.
The use of human-derived botulinum antitoxin may also be helpful.
When the condition is detected and treated early, the child most often makes a full recovery. Death or permanent disability may result in complicated cases.
Respiratory insufficiency can develop. This would require assistance with breathing (mechanical ventilation).
Infant botulism can be life threatening. Go to the emergency room or call the local emergency number (such as 911) right away if your infant has symptoms of botulism.
In theory, the disease might be avoided by preventing exposure to spores. Clostridium spores are found in honey and corn syrup. These foods should not be fed to infants less than 1 year old.
