Abstract | Rodents have adverse effects on the natural environment and can threat public health by transmitting many zoonotic diseases. This study aimed to identify the types of commensal rodent species and their populations in three localities of the North Sinai Governorate, Egypt, and to determine the impacts of locality, gender, and season on the pattern of the distribution. The rodents were captured using wire-live traps from December 2016 to November 2017 at three localities (Bir El`Abd, Rabaa, and Qatia). A fixed number of baited traps were applied during the night once monthly. A total of 119 rodents were trapped and transported to the laboratory. Four rodent species belong to the family Muridae were classified according to reference keys. The most common captured rodent species was R. norvegicus (68.91%), and the least common species was M. musculus (2.52%). The highest rodent prevalence was recorded in Bir El-`Abd (63.87%), and the highest rodent index was recorded in the fall season (index=0.175). In conclusion, this study identified three rat species (R. norvegicus, R. r. frugivorus, and R. r. alexandrinus), and one mouse species (M. musculus) captured from three locations in North Sinai, Egypt. These rodents could cause economic impacts and health hazards to humans and animals.
