We propose a new mathematical model to investigate the effect of the introduction of an exposed stage for the cats who become infected with the T. gondii parasite. but that are not still able to produce oocysts in the environment. The model considers a time delay in order to represent the duration of the exposed stage. https://www.spidertattooz.com/OPI-Infinite-Shine-Combo-Base-Top-Indefinitely-Baby-ISL55-p26708/
