Rabies neutralizing antibody response to different schedules of serum and vaccine inoculations in non-exposed persons. 3.

This study is the third in a series on virus-neutralizing antibody response to different schedules of antirabies serum and vaccines in previously non-exposed persons. Three types of vaccine were studied-phenolized (Semple), duck embryo and high-egg-passage (HEP) chicken embryo. Reduced schedules of vaccine, consisting of 2-7 inoculations given at various intervals, did not give results comparable in efficacy (time of appearance, level and persistence of antibody) with schedules comprising at least 14 daily inoculations of vaccine as determined in previous trials. The effectiveness of a booster dose in previously sensitized individuals was confirmed with a demonstration that a rise in serum antibody appears between 4 and 8 days after the booster inoculation. Effective sensitization appears to be as much a function of spacing of inoculations as of total dosage of vaccine antigen. Interference by immune serum with the antigenicity of subsequently administered vaccine, noted previously by the present authors and by other workers, was again confirmed. This interference could be overcome by the administration of a sufficient amount of vaccine.

Studies in swine of Asian influenza virus.

This article reports on experiments with 6- to 8-week-old pigs infected with a human isolate of Asian strain influenza virus and on the successful passage of this virus into a second group of pigs. These findings are discussed in relationship to negative results obtained by others when swine sera, collected from apparently healthy animals before and after the recent Asian influenza epidemic, were tested for the presence of complement-fixing and haemagglutination-inhibiting antibodies.Six "normal" pigs were inoculated intranasally with 1.0 ml of fluid containing approximately 3 200 000 EID(50) of Asian influenza virus. Clinical evidence of disease was not apparent, but Asian strain virus was isolated from four of the pigs and the development of haemagglutination-inhibiting antibody to A/Asia/Japan/305/57 antigen was detected in all of them. Virus isolated from the first group was inoculated intranasally into another group of six "normal" pigs. Clinical evidence of illness was also absent in this group, but Asian strain virus was isolated from five pigs. Haemagglutination-inhibiting antibody developed in all six pigs but complement-fixing antibody in none.The authors conclude that the available evidence indicates that swine did not play a significant role in the epidemiology of the Asian influenza epidemic in the USA, and that the Asian strain appears not to have established itself in swine.

Fluorescent antibody staining of rabies virus antigens in the salivary glands of rabid animals.

Staining with fluorescent antibody of street rabies antigens in smears made from the salivary glands of rabid animals is described.The salivary glands of 157 animals, including dogs, foxes, cats, pigs, cows, one squirrel and one rat were processed with fluorescent antibody. In addition, staining was carried out for Negri bodies and virus isolation studies were made on the brains and salivary glands. By virus isolation from the brains, a total of 55 animals were found to be rabid. Of these, 51 were shown to have demonstrable Negri bodies and 49 were found to excrete virus in the salivary gland. Forty-eight of these 49 were found to have antigens in the salivary glands which could be stained by fluorescent antibody techniques and demonstrated by microscopic examination of smears made from six different areas of the glands.

Human antirabies gamma globulin.

To obviate the foreign protein reactions experienced with the use of hyperimmune serum in rabies-exposed individuals, an attempt was made to produce a rabies antiserum of human origin.Five doses of an inactivated rabies virus duck-egg vaccine were administered to 34 volunteers at 4-day intervals (i.e., on days 0, 4, 8, 12 and 16). An additional dose of chick-embryo attenuated virus vaccine-Flury HEP (high egg passage)-was given on the 46th day, followed by a final booster dose of duck-egg vaccine on the 288th day. Twenty-four days later, i.e., on the 312th day after the first dose, the participants were bled and the serum pooled and converted to gamma globulin.These volunteers, having no initial antibody, responded with variable titres, the pooled serum having a titre of 1: 100 against 50 LD(50) of rabies virus in neutralization tests and the gamma globulin prepared from this pool a titre of 1: 300.In five individuals inoculated with the antirabies gamma globulin, blood samples tested at intervals for residual antibody showed significant titres through 21 days.While the passive antibody levels resulting from the administration of a more potent immune horse serum were much higher than those achieved by the weaker human antirabies gamma globulin used, the decrease in titre was more gradual with the human globulin. With more booster inoculations in a larger group of human volunteers, it is believed that a human rabies immune gamma globulin could be produced which would be equal in effect to immune horse serum. The advantages of a human source of antibody in rabies prophylaxis are discussed.
