Various techniques have been used in studying antibody responses following infection with pox viruses. Ofthe in vitrotests the complement fixation and haemagglutination inhibition techniques have proved most convenient, but the antibodies concerned are apparently diiferent from neutralizing antibody (Chu, 1948). Estimation of this antibody to certain members of the group, such as ectromelia and vaccinia viruses, may be made in susceptible animals. Variola virus does not, however, produce lesions in the common laboratory animals with sufficient regularity to make such neutralization tests practicable. But it does constantly give rise to recognizable focal lesions on the chorio-allantois of developing chick embryos. This tissue, susceptible to most members of the pox group, has therefore been used in previous studies (McCarthy & Downie, 1948; Downie & McCarthy, 1950), employing the technique developed by Burnet and his colleagues for vaccinia and other viruses (Burnet, 1936; Keogh, 1936; Burnet, Keogh & Lush, 1937; Burnet & Lush, 1939).

Pseudorabies is a very fatal but non-contagious disease in cattle and the common laboratory animals. It is a relatively mild yet highly contagious disease in swine. It has been shown that in swine the nose serves both for the entrance and the exit of the virus. Furthermore, it has been observed that fatal pseudorabies infections in rabbits can be induced merely by bringing their abraded skin into contact with the noses of infected swine. The blood sera of swine on two farms where pseudorabies had occurred among the cattle were found to be capable of neutralizing pseudorabies virus. It is believed that in these instances the swine had a mild and unrecognized pseudorabies infection and transmitted their disease to the cattle with which they were associated, by transfer of the virus on their noses to the abraded skin of the cattle.

Human Intestinal Tract

These experiments show that the common laboratory animals are about equally sensitive to the x-ray given over the abdomen. The clinical reaction following a M.L.D. is very similar and the intestinal pathology almost identical. The rat and guinea pig are slightly more sensitive to the x-ray than are the dog, cat, and rabbit. By contrast birds, frogs, and reptiles are very resistant to the x-ray and may tolerate two or three doses of radiation lethal for dogs. We can offer no convincing explanation for this fact which is discussed above. These data strengthen our belief in the scattered and incomplete observations on human cases which indicate that the human intestinal tract is likewise sensitive to radiation. This fact must be given careful consideration in conditions where abdominal or pelvic radiation is being used because such injury done to intestinal epithelium is always serious and in some cases irreparable.
