ABSTRACT
Rodents are associated with the spread of deadly zoonotic and emerging infectious diseases. Their widespread distribution is strongly linked to their ability to thrive in human-altered environments with access to food and shelter. Thus, humans are exposed to zoonotic agents that can spread and infect them directly and indirectly. We sourced published literature on ectoparasites associated with Rattus rattus, R. norvegicus, and Mus musculus from various academic databases such as Google Scholar, PubMed, Web of Science, and Scopus. The relevant literature was screened and selected in R statistical software using the packages ”metagear” and ”revtool.” We reviewed and analyzed a total of 53 articles published between 1994 and 2024. The literature review covered studies from 29 countries, represented by six continents, namely, Africa, Asia, Europe, North America, Oceania, and South America, with the majority of the studies from Asia. R. rattus had the most published studies. Our literature review identified 87 species of zoonotic ectoparasites, with Xenopsylla cheopis, Polyplax spinulosa, and Laelaps echidninus being the most reported across all host species. Mites were the most reported ectoparasites (40.83%), followed by fleas (25%), ticks (20%), and lice (14.17%). Most of these ectoparasites were reported from R. rattus, with the highest number of documented ectoparasites. Investigating the prevalence, distribution, and potential risks of alien invasive rodents and their ectoparasites is paramount for public health and improving integrated pest management control strategies.
