Therapeutic Effects of Matricaria chamomilla Extract in an Immunosuppressed Mouse Model of Cryptosporidiosis

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Chamomile (Matricaria chamomilla) extract significantly reduced oocyst shedding and intestinal lesions in immunosuppressed mice infected with Cryptosporidium parvum, while enhancing antioxidant defences (GPx, TAC). These findings suggest chamomile as a promising phytotherapeutic agent for cryptosporidiosis. ABSTRACT Background Cryptosporidiosis, caused
