Parasitized animals can be hazards for the human population health. The current study aimed to determine parasitic helminths infection in 1070 trapped small mammals from Cotonou town in Benin. Rodents and shrews were trapped using wire netting traps and anesthetized. The gastrointestinal tracts were removed and examined to identify parasitic helminths. The results indicated that 6 % (65/1070) of the examined small mammals were infected with nine helminths species including Moniliformis moniliformis (40.3%), Mastophorus muris (6%), Rictularia sp. (4.5%), Nematoda sp. (1.5%), Catenotaeniapusilla (3%), Hymenolepis diminuta (34.3%), Hymenolepis spp. (1.5%), and Rodentolepis fraterna (7.55%), Rodentolepis microstoma (1.5%). No helminths were found in shrews. There was no difference in the prevalence according to the sex of parasitized hosts. The examined rodents were more infected with Moniliformis moliniformis than other helminths. As rodents are reservoirs of several zoonotic parasites, then, the control of these animals has an important role in the public health safeguarding.
