Abstract

The present paper gives the base-line data on the blood picture of various sexes and age groups of commensal, domestic and field rodents in Egypt.
According to the haemopoetic activity of these animals based on descending values of haemoglobin percentages, eryrthoplastid and leucocytic counts, and ascending values of bleeding, coagula tion and prothrombin times, these animals might be arranged in the following order :
Rattus norvegicus, R. r. alexandrinus, Acomys cahirum, R. r. frugivorus, and Arvicanthis niloticus.
All of them showed high lymphocytic count. followed by neutro phils, monocytes, eosinophils and finally basophils.
It was concluded that animals feeding essentially on protein diets such as R. norvegicus, Ac. cahirinus and R. r. alexandrinus tended to show pronounced haemopoetic activity and more coa gulability than the remaining rats which feed on less protein diets.
re
Variations due to age and sex of these animals were also corded.
