| survey for antibodies to respiratory viruses in two groups of sheep in northern ireland. | two hundred serum samples from texel and texel crossbred sheep (non-indigenous breeds) and 200 from indigenous northern ireland breeds (mainly blackface, cheviot and border leicester crosses) were tested for antibodies to parainfluenza virus types 1, 2 and 3, respiratory syncytial virus, bovine adenovirus (subgroups 1 and 2), influenza type a, maedi-visna virus and bovine virus diarrhoea virus. the percentage of animals with antibodies to parainfluenza virus 3 (50 to 56 per cent) and adenovirus ... | 1984 | 6095511 |
| investigation of seroprevalence of respiratory virus infections in an infant population with a multiantigen fluorescence immunoassay using heel-prick blood samples collected on filter paper. | respiratory viruses are an extremely common cause of childhood morbidity. however, the current seroprevalence of viruses in infant populations is difficult to establish because invasive venipuncture may be technically and ethically unacceptable. this prospective study aimed to establish the seroprevalence of respiratory viruses in an infant population by use of a novel multiantigen fluorescence immunoassay against common respiratory viruses, using heel-prick blood samples collected on filter pap ... | 1999 | 10367768 |
