The aim is to establish a reliable in vitro assay to evaluate the effectiveness of anti-cryptosporidial drugs against Cryptosporidium parvum.
Developed a luciferase-based assay to monitor C. parvum growth in HCT-8 cells.
Examined experimental parameters such as sodium taurocholate treatment and serum concentration.
Analysed morphological changes in parasites during different developmental stages.
Sodium taurocholate treatment significantly increased parasite infectivity.
Removing non-invaded parasites at 3 hours post-infection increased luciferase activity by approximately 2-fold at 24 hpi.
Monensin and kijimicin showed strong in vitro activity, while diclazuril and toltrazuril had limited effectiveness.
