Ecto-parasites infesting commensally rodents were collected
from different localities in Tallcha Center (Dakahlia Governorate)
from April 2006 to March 2007. The seasonal abundance of rodent
number and rat index was 52 (0.58) in spring, 27 (0.3) in summer,
39 (0.22) in autumn and 17 (0.05) in winter. From 135 rodent
species and rat index was Rattus norvegicus N=33 (0.24), R. r. frugivorous
N=39 (0.29), R. r. alexandrinus N=48 (0.36) and Mus musculus
N=15 (0.11). From 388 ecto-parasite infested rodent collected
number and ecto index was fleas N= 114 (0.84 flea/rat), Lice
N=93 (0.69 lice/rat), Mites N= 165 (1.2 mite/rat) and larva of ticks
N=16 (0.12 tick/rat). No doubt, rodents and their ecto-parasites
play an important role in spreading and transmission of zoonotic
diseases to human and animal. |
