| 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). | 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 ant ... | 1985 | 3936735 |
| outbreak of newcastle disease due to pigeon paramyxovirus type 1 in grey partridges (perdix perdix) in scotland in october 2006. | in october 2006, following an initially non-statutory disease investigation affecting 12-week-old grey partridges (perdix perdix), an outbreak of newcastle disease due to infection with the avian paramyxovirus type 1 virus responsible for the current panzootic in pigeons (ppmv-1) was confirmed in scotland. two pens of partridges were affected by signs including loss of condition, diarrhoea, progressive neurological signs and mortality totalling approximately 24 per cent, and laboratory evidence ... | 2009 | 19880861 |
| immune challenge affects female condition and egg size in the grey partridge. | as maintenance of the immune system is energetically costly and resource-limited, trade-offs among immune function, body condition, and reproductive allocation are expected. in this study, we experimentally test the possible trade-off between immune response, self maintenance, and reproductive output in breeding grey partridges perdix perdix. before laying, half the females were immune challenged with a novel antigen vaccine (newcastle disease virus, ndv). the challenged females showed a higher ... | 2010 | 20665708 |
