| nucleotide sequence of e1 region of canine adenovirus type 2. | the nucleotide sequence of the leftmost ecori-c fragment (0 to 11.3%) of canine adenovirus type 2 (cad2) which could transform rodent cells morphologically but required additional sequences from 10 to 32 map units (m.u.) for full expression of its oncogenic potential was determined. the ecori-c fragment contains 3609 nucleotide base pairs (bp) encoding e1a, e1b, and pix genes. although the nucleotide sequence of cad2 e1 shows little homology to those of human ads, the amino acid sequences of the ... | 1989 | 2800332 |
| molecular cloning and restriction endonuclease mapping of two strains of canine adenovirus type 2. | the dna of a field isolate and of a vaccine strain of canine adenovirus type 2 (cav-2) were analysed by digestion with several restriction endonucleases. the psti restriction fragments of the field isolate (cav-2 glasgow) and the vaccine strain were cloned into the plasmid pbr322. physical maps of the two viral genomes were constructed by molecular hybridization of psti, ecori, smai, bamhi and kpni digests of the viral dna with the cloned psti fragments. the restriction profile of cav-2 glasgow ... | 1989 | 2732685 |
| identification and nucleotide sequence of the early region 1 from canine adenovirus types 1 and 2. | the genome of canine adenovirus type 1 (cav-1) has been cloned and restriction maps compiled. these maps are compared with those of canine adenovirus type 2 (cav-2). the left ends of both genomes were further characterised by dna sequence analysis. several features of the dna sequence and predicted polypeptide sequence are similar to those of the human adenoviruses. the level of homology observed across the e1 regions appears to be of the same order as the overall dna similarity between cav-1 an ... | 1989 | 2623943 |
| large and small plaque variants of canine adenovirus 2 isolate. | 1989 | 2557478 | |
| effects of vaccines on the canine immune system. | the effects of several commercially available polyvalent canine vaccines on the immune system of the dog were examined. the results demonstrated that the polyvalent vaccines used in this study significantly suppressed the absolute lymphocyte count and that most of the polyvalent vaccines significantly suppressed lymphocyte response to mitogen, but had no effect on natural effector cell activity, neutrophil chemiluminescence, nor antibody response to canine distemper virus. the individual vaccine ... | 1989 | 2540897 |
| incomplete particles of canine adenovirus type 1: occurrence and structure. | replication of canine adenovirus (cav) type 1 in dog kidney (dk) cells has been found to generate particles containing double-stranded dna molecules of size 6-9 kbp with protein moieties at their 5' termini. the particles formed a discrete band in cscl gradients at a density intermediate to that of intact virions and empty capsids. electron microscopy demonstrated that they were morphologically similar to intact virions. restriction enzyme digests and hybridization experiments revealed the exist ... | 1989 | 2815582 |
| vaccine-associated canine distemper infection in a litter of african hunting dogs (lycaon pictus). | four, 57 days old, african hunting dog puppies (lycaon pictus) from one litter died within three weeks following vaccination with modified-live canine distemper virus (cdv) and killed canine adenovirus type 1, canine parvovirus and leptospira icterohemorrhagiae and canicola. 18 days post vaccination, the animals developed neurologic disease characterized by episodes of grand mal seizures and circling. macroscopic, histological and immunohistochemical studies revealed acute systemic cdv infection ... | 1990 | 2385981 |
| [purification and properties of the hexon antigen of canine adenovirus serotype cav-1]. | the main antigen and immunogen of canine adenovirus type 1 (cav-1) has been purified to near homogeneity from cultural fluid of a cav-1-infected primary cell culture by hydrophobic and anion-exchange chromatography. the hexon native form (trimer) was shown to be resistant against denaturation by sds under conditions of sds-page performed without heating the samples. the monomer chain of the cav-1 hexon was apparently identical in terms of electrophoretic mobility with that of the previously sequ ... | 1990 | 2085617 |
| changes in lung mechanics and reactivity with age after viral bronchiolitis in beagle puppies. | we measured changes with growth in lung function and airway reactivity after acute canine parainfluenza virus type 2 (cpi2, n = 5), canine adenovirus type 2 (cav2, n = 7), and sequential cav2-cpi2 (n = 6) infections or no infection (controls, n = 6) in beagle puppies (age approximately 79 days). in the cpi2 and cav2 groups, a lower respiratory illness developed by day 3 postinfection with clinical recovery by day 14. in the cav2-cpi2 group, puppies were inoculated initially with cav2 and 12 days ... | 1990 | 1963888 |
| localization of inflammation and virions in canine adenovirus type 2 bronchiolitis. | beagle puppies develop bronchiolar inflammation and histamine hyperresponsiveness with canine adenovirus type 2 (cav2) infections. we determined the distribution of bronchiolar lesions and correlated inflammation with virions and bronchoalveolar lavage fluid (balf) cytology. nineteen beagle puppies were inoculated with tissue culture fluid (control puppies, n = 8), or cav2 (cav2, n = 11). the puppies had clinical assessments and measurements of lung resistance (rl), and dynamic compliance (cdyn) ... | 1990 | 2167625 |
| acute canine adenovirus 2 infection increases histamine airway reactivity in beagle puppies. | acute infection with canine adenovirus was studied in 23 specific pathogen-free outbred beagle puppies (median age = 78 days, range = 67 to 86 days) to determine its effects on pulmonary function and airway responsiveness to aerosolized histamine. the following groups were studied: uninoculated (n = 6, control); inoculated with canine adenovirus type 2 (cav2) (n = 11, infected); and subclinical spontaneous infection with cav2 (n = 6, subclinical). while anesthetized with chloralose and mechanica ... | 1990 | 2154153 |
| a mutant of canine adenovirus type 2 with a duplication of the e1a region exhibits altered expression of early region 4. | the genomic dna of a vaccine strain of canine adenovirus type 2 (vaxitas; ici tasman) has been shown to contain two copies of the e1a region, the second being at the far right end of the genome. dna sequence analysis of the right terminal 2.8 kbp of this vaccine strain showed that numerous point mutations have occurred in the second copy, which would preclude the synthesis of any functional products. however, expression vectors in which the e1a promoter from the right terminus were linked to the ... | 1991 | 1832708 |
| sequence analysis of putative e3 and fiber genomic regions of two strains of canine adenovirus type 1. | the nucleotide sequences of the genomes of two strains of canine adenovirus, type 1 (glaxo and cll) have been determined within the region spanning approximately 0.80-0.91 map unit. homology comparisons with other adenoviral dnas indicate that this region contains part of the hexon-associated protein (pviii) precursor gene on the left, and a 57-kda fiber-encoding gene on the right. in both viral strains, the sequences of these genes are identical. accepting the generally highly conserved nature ... | 1991 | 1828920 |
