Preliminary studies on genetic resistance or susceptibility of sheep to gastro-intestinal nematodes

, : Preliminary studies on genetic resistance or susceptibility of sheep to gastro-intestinal nematodes. Acta Parasitologica 39(1): 25-28

On the basis of the faecal examination and necropsies, prevalence of infection, number of species and egg counts (EPG) were estimated. A comparison of EPG of ewes and their lambs showed, that of the group of lambs with the lowest EPG, 25% were from resistant mothers while in the group with the highest EPG - 31.25%.

To study further soluble factors which regulate contact sensitivity (CS) to 2,4-dinitrofluorobenzene (DNFB), hapten-primed spleen cells from BALB/c mice were used to make T-cell hybridomas. A hybrid constitutively producing a suppressor factor was...

Furthermore, HSP can run a more serious course in adults, compared to children, in w...
