Abstract
METHODS for the recovery and counting of adult Nippostrongylus brasiliensis from the intestines of adult rats have been described by Jennings et al.1 and Ogilvie2. Such methods need to be very accurate, particularly where estimations of the degree of immunity of the host are to be made on the basis of such counts. The techniques described by these authors have been used routinely in this laboratory during experiments on adult rats and have proved quite satisfactory. However, on application to the recovery of worms from the intestines of neonatal or unweaned rats a number of difficulties were encountered.
