Results of investigation of small mammals trapped in 3 villages in Mali, 2009
| Village | No. total captures (trap success, %)* | No. non–Mastomys spp. captures | No. Mastomys spp. captures (trap success, %) | No. (%) Lassa-positive M. natalensis mice |
|---|---|---|---|---|
| N’Tessoni | 25 (14.9) | 8† | 17 (10.1)‡ | 0 |
| Soromba | 25 (15.0) | 0 | 25 (15.0) | 6 (24) |
| Doneguebougou | 53 (21.1) | 13† | 40 (15.9)‡ | 0 |
*Trap success is defined as the total number of individual rodents captured divided by the cumulative total of traps set at each location, multiplied by 100.
†Non-Mastomys species captured included 1 Praomys daltoni (Dalton’s mouse), 3 Mus musculoides (Temminck’s mouse), 3 Crocidura olivieri (giant shrew), and 1 Arvicanthis niloticus (grass rat) from N’Tessoni and 1 Praomys daltoni, 1 Rattus rattus rat, 1 Arvicanthis niloticus, 3 Crocidura viaria (savannah path shrew), and 7 Crocidura olivieri from Doneguebougou.
