An Attempt at Embryo Transfer as a Means of Controlling Bordetella bronchiseptica Infection in the Rabbit

Abstract

Embryo transfer was attempted in order to control disease in rabbits. Embryos were collected by flushing of the oviducts of donor rabbits on Day 2 of gestation, into small tubes containing the medium, transported within the body warmth of the person carrying the tubes and transferred into the oviducts of SPF pseudopregnant recipients. The time between embryo collection and transfer was 7-8 hours. Ten of 56 embryos derived from Bordetella bronchiseptica infected animals developed into newborns. As a result of bacteriological examination of intranasal exudate in six weanlings, no pathogens were detected. We suggest that embryo transfer is an effective and simple alternative to caesarian operation in Bordetella bronchiseptica infected rabbits.
