Different species of rodents are potential transmitters of multiple zoonotic agents such as Leptospira spp., a spirochete that causes leptospirosis. This is an infectious disease that has a negative impact on pig production because it generates large productive, reproductive and economic losses. In swine farms, the most common rodent species are house mice (Mus musculus), brown rats (Rattus norvegicus) and black rats (Rattus rattus), which act as maintenance hosts for different serovars of Leptospira, contaminating the environment, food and water through urine, and putting human and animal health at risk. For this reason, the objective of this article is to describe the role of rodents in the transmission of Leptospira in swine farms. For this purpose, a bibliographic search was carried out in different databases such as Science Direct, Scopus, Redalyc, PubMed and SciELO. The results of the literature review show that there are few studies that report the importance of rodents in the transmission of Leptospira in swine farms. The onset of the disease depends to a large extent on the presence, contact and control of rodents in farms, although environmental factors, agent survival and hygiene, among others, must also be considered.
