The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace Jan 1977

The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace

Masters Theses

A total of 38 Mus musculus were used to compare superovulation to normal ovulation in three different areas of the reproductive cycle. The areas studied include the fertilization and abortion rates, alternation of ovarian function, and normalization of estrus cycling. No statistically significant differences were noted between the two groups in either fertility rates or abortion rates. A distinct difference was noted in alternation of ovarian function. Normally ovulating mice showed a distinct right or left preference in the number of ova ovulated from each ovary. Animals showing a left preference exhibited approximately a 2:1 ratio and animals with ...


Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri Jan 1977

Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri

Masters Theses

Hepatozoon and microfilariae are described from the blood of fox and gray squirrels captured in Coles and Lake Counties in Illinois during 1976 and 1977. The hepatozoon species is identified as Hepatozoon griseisciuri on the basis of parasite morphology and hosts. A higher rate of infection (35.7% : 11.1%) was observed in gray squirrels than in fox squirrels and more adults were infected than juveniles. No microfilariae were found in gray squirrels but fox squirrels had a 57.1% infection rate with no difference based on age. The observed microfilariae are similar to that described by Davidson from Maryland ...
