摘要：
Studies were conducted into effects of Rift Valley fever virus on oestrous and vaginal cytology in non-pregnant ewes. 6 pregnant and 8 non-pregnant local Barki ewes were subcutaneously inoculated with different doses of virus isolated from Sharkia Province. Observed were irregularities in the oestrous cycle (20-28 days inoculation) and anoestrum. The anoestrum smears included large non-cornified epithelial cells with large well staines centrally located nuclei together with a large number of bacteria. Abortion and retention of placenta occurred in pregnant ewes with prolonged puerperal heat up to 70 days. Inoculation of virus was followed by thermal response. Re-isolation of virus in BHK cells was possible from aborted foetuses and placenta.
