Antibody response in partridge (Perdix perdix L.) 1. Effect of sex and age on the immune response to sheep red blood cells (SRBC), Newcastle disease virus (NDV) and Brucella abortus (Buck 19). 1985

To ascertain the immune response capacity of Partridges to classical experimental and natural antigens, dose and time response curves to sheep red blood cells (SRBC), Newcastle disease virus (NDV) and Brucella abortus (Buck 19 strain), were determined in two strains reared in two different farms. 1 ml of 20% SRBC, 10(9) NDV particles and 10(7) Buck 19 microorganisms, gave optimal antibody responses seven (SRBC and Buck 19) or fourteen days after immunization. As far as SRBC is concerned, the antibody response was sex independent, but declined markedly in partridges older than 1 year. The immunization schedule used by us allow the identification of high and low responder animals. In fact, highly significant correlation in individual partridges between antibody titers obtained after two successive immunizations to an optimal SRBC dose given three weeks apart, was found. This fact, together with the observed great variability in the antibody response to the three antigens considered, should allow a selection for high and low responder lines, in order to improve the fitness toward environmental pathogens.

D009522 Newcastle disease virus The most well known avian paramyxovirus in the genus AVULAVIRUS and the cause of a highly infectious pneumoencephalitis in fowl. It is also reported to cause CONJUNCTIVITIS in humans. Transmission is by droplet inhalation or ingestion of contaminated water or food. Avian Paramyxovirus 1,Paramyxovirus 1, Avian
D002003 Brucella abortus A species of the genus BRUCELLA whose natural hosts are cattle and other bovidae. Abortion and placentitis are frequently produced in the pregnant animal. Other mammals, including humans, may be infected. Bacterium abortus,Brucella melitensis biovar abortus

D000367 Age Factors Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
