Amixicile reduces severity of cryptosporidiosis, but does not have in vitro activity against Cryptosporidium [Mechanisms of Action]

Cryptosporidium causes significant morbidity in malnourished children. Nitazoxanide (NTZ) is the only approved treatment for cryptosporidiosis, but NTZ has diminished effectiveness during malnutrition. Here we show that amixicile, a highly selective water soluble derivative of NTZ diminishes Cryptosporidium severity in a malnourished mouse model despite a lack of direct anti-cryptosporidial activity. We suggest that amixicile; by tamping down anaerobes associated with intestinal inflammation, reverses weight loss and indirectly mitigates infection-associated pathology.
