Abstract

has been identified as one of the prevalent opportunistic parasites that cause diarrhea, which may be persistent and fatal. Current chemotherapeutic agents, including nitazoxanide (NTZ), are frequently associated with therapeutic failure, and their roles in the induction of apoptosis in cryptosporidiosis remain to be a topic of debate. Thus, this study aimed to assess the apoptotic changes in cryptosporidiosis in immunocompetent (IC) and immunosuppressed (IS) mice after treatment with silver nanoparticles (AgNPs) and NTZ either alone or after loading. In total, 120 laboratory-bred Swiss albino mice were divided into two groups. Group A included IC mice, while Group B included IS mice. Both groups were divided into six subgroups: noninfected nontreated, infected nontreated, infected AgNP-treated, infected NTZ-treated, infected AgNP-loaded NTZ (full-dose)-treated, and infected AgNP-loaded NTZ (half-dose)-treated. The assessment was achieved through parasitological, histopathological, and apoptotic marker expression evaluation. AgNP-loaded NTZ (different doses) treatment showed the highest oocyst shedding reduction and remarkable improvement in histopathological changes, followed by individual treatment with NTZ and then AgNPs in IC and IS mice. Results of apoptotic marker expression revealed that AgNP-loaded NTZ treatment exhibited a promising role in regulating apoptotic changes in cryptosporidiosis through the expression of the lowest levels of cytochrome C and caspase-3 in IC and IS mice at the end of the experiment. Therefore, AgNP-loaded NTZ can be a potential therapeutic agent against cryptosporidiosis for IC and IS mice.
