|---|---|
| lentiviruses, feline | A subgenus of lentivirus comprising viruses that produce multi-organ disease with long incubation periods in cats. (12 Dec 1998) |
| leukaemia, feline | A neoplastic disease of cats frequently associated with feline leukaemia virus infection. (12 Dec 1998) |
| leukaemia virus, feline | A species of mammalian type c retrovirus (retroviruses type c, mammalian) causing leukaemia, lymphosarcoma, immune deficiency, or other degenerative diseases in cats. Several cellular oncogenes confer on felv the ability to induce sarcomas (see also sarcoma virus, feline). (12 Dec 1998) |
| acute viral conjunctivitis | An epidemic inflammation of the conjunctiva marked by follicles, especially in the lower fornix; may be caused by adenoviruses, herpesvirus, and Newcastle disease virus. (05 Mar 2000) |
| antibodies, viral | Immunoglobulins produced as a response to viral antigens; includes all classes of immunoglobulins elicited by all viral components. (12 Dec 1998) |
| antigens, viral | Substances elaborated by viruses that have antigenic activity. (12 Dec 1998) |
| antigens, viral, tumour | Those proteins recognised by antibodies from serum of animals bearing tumours induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation. (12 Dec 1998) |
| avian viral arthritis virus | A virus of the genus Reovirus, family Reoviridae, causing tenosynovitis and arthritis in chickens. (05 Mar 2000) |
| bronchiolitis, viral | An acute inflammatory disease of the upper respiratory tract, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are parainfluenza type 3 and respiratory syncytial virus. (12 Dec 1998) |
| gene expression regulation, viral | Any of the processes by which cytoplasmic factors influence the differential control of gene action in viruses. (12 Dec 1998) |
| genes, structural, viral | DNA or RNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of viral cells. (12 Dec 1998) |
| genes, viral | The hereditary material of viruses, consisting in all DNA and some RNA viruses of a single molecule of nucleic acid, and in some RNA viruses of several separate pieces of RNA. (12 Dec 1998) |
| genome, viral | The complete gene complement contained in a DNA or RNA molecule in a virus. (12 Dec 1998) |
| viral | Pertaining to, caused by or of the nature of virus. (18 Nov 1997) |
