“…In reality, overlapping wild and domestic felid populations sharing an environment likely consume a wide diversity of prey species that would be difficult to incorporate into traditional transmission models. In a unique model including a domestic cat population, multiple prey species, and direction of hydrologic flow, water-borne transmission was identified as a critical component of T. gondii infection [175]. While these models provide important insight on parasite transmission dynamics, a broader scale approach is still needed to investigate environmental transmission in areas with multiple felid populations.…”

Environmental transmission of extremely resistant Toxoplasma gondii oocysts has resulted in infection of diverse species around the world, leading to severe disease and deaths in human and animal populations. This review explores T. gondii oocyst shedding, survival, and transmission, emphasizing the importance of linking laboratory and landscape from molecular characterization of oocysts to watershed-level models of oocyst loading and transport in terrestrial and aquatic systems. Building on discipline-specific studies, a One Health approach incorporating tools and perspectives from diverse fields and stakeholders has contributed to an advanced understanding of T. gondii and is addressing transmission at the rapidly changing human–animal–environment interface.

In this paper, we present an epidemiological model to study the dynamics of toxoplasmosis in cat and mouse populations under a continuous cat vaccination program. We construct a mathematical model at the cat and mouse populations level that includes the effect of oocysts of the parasite T. gondii which causes the toxoplasmosis infection. We include vertical transmission in both populations. We prove that the basic reproduction number $${\mathcal {R}}_{0}$$ R 0 is a threshold parameter that determines the global dynamics and the outcome of the toxoplasmosis disease in the cat and population. Numerical simulations are presented to support the theoretical results and to show the impact of a vaccination program for cats. In addition, the simulations give insight on the effect of a public health program related to removing the oocysts from the environment. These simulations show the effectiveness of a constant vaccination intervention and a oocysts clearance program.
