In México, N. brasiliensis has been recorded from M. musculus in Tabasco (Cigarroa-Toledo et al. 2017), R. rattus in Hidalgo (Pulido-Flores et al. 2005) and Tabasco (Cigarroa-Toledo et al. 2017), and R. norvegicus in Michoacán (Hierro-Huerta 1992) and Tabasco (Cigarroa-Toledo et al. 2017). In Yucatán, this species has been previously reported from M. musculus and R. rattus in three localities in Mérida and Opichén (Panti-May et al. 2015, 2017).
