What test would be most helpful in diagnosing the condition of a 5 month old male infant who is lethargic, has a weak cry, and poor feeding?

• A. Complete blood count
• B. Stool for botulinum toxins
• C. Urinalysis
• D. Cerebral ultrasound

Answer: (B)

In the context of a 5-month-old male infant who is lethargic, has a weak cry, and is exhibiting poor feeding, testing for botulinum toxins is particularly relevant. The symptoms described are suggestive of infant botulism, which is a rare but serious condition caused by the ingestion of Clostridium botulinum spores. These spores can be found in honey, poorly processed foods, or contaminated environmental sources. In cases of suspected infant botulism, a stool sample to test for botulinum toxins can help confirm the diagnosis. The presence of these toxins in the stool is an indication that the infant has ingested the spores which are now producing the toxin in their intestine, leading to the observed symptoms. Early diagnosis is crucial for effective management and intervention. While a complete blood count can provide information on infection or other hematological issues, it is less specific for diagnosing the condition directly affecting the infant's current state. Urinalysis typically assesses the urinary tract and kidney function, which is not directly relevant to the symptoms presented. A cerebral ultrasound, while useful for evaluating neurological conditions, does not address the digestive symptoms and potential toxin exposure that are key considerations in this scenario. Therefore, testing for botulinum toxins
