Interaction between acari ectoparasites and rodents in Suez Governorate, Egypt.
From the medical point of view, the relation between man and rodents comes in the priority. Some rodent populations are wild but others are commensal and live in close association with man. They steal his food and conveying many zoonotic diseases. Their arthropod ectoparasites play an important role in conveying or transmitting these zoonotic diseases. Several disorders and diseases of man are tick borne relapsing fever, Rocky mountain spotted fever, Lyme disease, and many others. Besides numerous species of mites occasionally infest man. They transmit several diseases as Rickettsia tsutsugamushi fever, epidemic haemorrhagic fever, and they cause severe allergic reaction. The results obtained are summarized in the following (1) Six species and subspecies of rodents were detected. In a descending order of abundance, they were (a) Rattus norvegicus, (b) Rattus rattus alexandrinus (c) Rattus rattus frugivorous (d) Acomys cahirinus (e) Gerbillus gerbillus asyutensis (f) Mus m. praetextus. (2) The most common rodent was R. norvegicus and the least common was M. musculus. (3) The collected ticks and mites were 2 genera of tick larvae; Rhipicephalus species and Hyalomma species. The collected mites were Ornithonyssus bacoti and Laelaps nuttali. (4) Most of the tick larvae were collected from wild rodents; Gerbillus g. asyutensis. (5) Most of the mites were collected from commensal rodents particularly R. norvegicus. Descriptive morphology and illustrations were given to the collected rodents and their acari ectoparasites.
