Serum specimens from 42 normal dogs and 42 with untreated malignant tumours were assayed for the presence of antibodies to human adenovirus types 5, 21 and 31 and to infectious canine hepatitis (ICH) virus. Radioimmunoassays using human adenovirus antigens showed that 71 per cent (30/42) of all dogs with tumours, but only 19 per cent (8/42) of all normal dogs, were positive for human adenovirus antibody. Canine sera reactive with antigens of one human adenovirus type in radioimmunoassays were also reactive with antigens of the other two types. Dogs bearing malignant lymphoma or squamous cell carcinoma tumours had higher levels of antibody against adenovirus type 5 antigens. Human adenovirus type 5 was neutralised by sera from four tumour-bearing and two normal dogs, while sera from two normal and five tumour-bearing dogs were positive in immunodiffusion tests with human adenovirus antigens. Levels of ICH antibody in sera of normal adult dogs and adult dogs with tumours were not markedly different when measured by radioimmunoassays. Likewise, sera from these two groups of dogs had similar ranges of ICH neutralising antibody titres. In contrast, levels of ICH antibody detected by the serological assays in sera from non-pet, non-vaccinated pups were either markedly low or absent. Possible explanations for the observed increased levels of human adenovirus antibody in sera of tumour-bearing canine pets are discussed.

A retrospective analysis of the clinical and laboratory findings from 51 adult horses with chronic diarrhoea revealed that the most common conditions were larval cyathostomiasis (14 cases), idiopathic chronic colitis (nine cases) and alimentary lymphoma (five cases). Five animals had diarrhoea as a result of non-alimentary disease. A diagnosis was reached in 37 cases, but only 15 were made ante mortem. Among the 18 animals (35 per cent) which survived, there were five cases of larval cyathostomiasis, one case of colonic impaction and 12 cases were undiagnosed. The most frequent abnormalities detected in blood samples from the horses were neutrophilia, hypoalbuminaemia, hyperglobulinaemia and high alkaline phosphatase activity. Evidence of carbohydrate malabsorption was found in 16 of 28 cases in which oral glucose tolerance tests were performed. No diagnostic specificity was apparent in either the clinical signs or the laboratory findings.

A novel cDNA clone (20.5) which is differentially expressed between two closely related T-lymphoma cell clones was isolated by subtraction-enriched differential screening. SL12.4 cells, from which the cDNA was isolated, have characteristics of thymocytes at an intermediate stage in development. A sister cell clone derived from the same tumor, SL12.3, does not express this mRNA, has a distinct phenotype, and expresses fewer genes required for mature T-cell function. The cDNA sequence predicts a highly hydrophobic protein (approximately 49.5 kilodaltons) which contains seven putative membrane spanning domains. The gene was expressed on concanavalin A-activated T lymphocytes and was designated Tea (T-cell early activation gene). The Tea gene mapped to chromosome 8 and appeared to be conserved among mammalian and avian species. The Tea gene is distinct from, but bears extensive amino acid and DNA sequence similarity with, the murine ecotropic retroviral receptor which is encoded by the Rec-1 gene. Neither gene product displayed significant homology with other known transmembrane-spanning proteins. Thus, the Tea and Rec-1 genes establish a new family encoding multiple membrane-spanning proteins.

We isolated a novel infectious murine leukemia virus (HoMuLV) from the wild mouse Mus hortulanus. HoMuLV has an ecotropic virus host range, but the viral DNA fails to hybridize to viral envelope segments specific for the known inbred and wild mouse ecotropic as well as nonecotropic MuLVs. Despite this difference in its env gene, HoMuLV appears to use the same ecotropic cell-surface receptor since it infects only hamster and mouse somatic cell hybrids which contain the Rec-1 ecotropic virus receptor on chromosome 5. Furthermore, HoMuLV does not infect mice carrying the Fv-4r allele which is thought to prevent ecotropic virus infection through an interference mechanism. HoMuLV is NB-tropic and, unlike other infectious MuLVs, does not grow in cells derived from the wild mouse species. M. dunni. Five to ten months after neonatal inoculation with HoMuLV, 72% of female NIH Swiss mice (8/11) contracted lymphoma or erythroid leukemia, but 33% of the inoculated males (5/15) developed erythroid or myelogenous leukemia within 8-16 months. These data suggest that NIH Swiss males and females differ in their susceptibility to HoMuLV-induced disease. Furthermore, NIH Swiss mice were found to be more susceptible to HoMuLV-induced disease than NFS/N mice. Tumors contained infectious MCF virus, which is consistent with the hypothesis that MCF virus may mediate tumorigenesis by HoMuLV.

The levels of c-myc mRNA and interleukin-2 receptors (IL-2 Rec) were studied in human peripheral blood lymphocytes (PBL); mature CD2+,CD3+ T cell clones and CD2+,CD3- natural killer (NK) cell clones, and CD2+,CD3+ and CD2-,CD3- T lymphoma cell lines. A transient induction of the expression of c-myc and IL-2 Rec was observed in PBL after activation with phytohemagglutinin (PHA). Expression of c-myc and IL-2 Rec was also found in the CD2+,CD3+ and CD2+,CD3- clones. The CD2+,CD3+ showed higher levels of c-myc mRNA and IL-2 Rec than the CD2+,CD3- clones. In three T lymphoma cell lines constitutively high levels of c-myc mRNA but no IL-2 Rec were found. Only in JURKAT (CD2+,CD3+), c-myc mRNA levels could be further enhanced by PHA. These results suggest that in the presence of PHA, expression of c-myc and IL-2 Rec is induced via the CD3 receptor, and in the absence of PHA and/or the CD3 receptor alternative routes of induction are involved.

The genetic and embryotoxic effects of bis(tri-n-butyltin)oxide (TBTO) were evaluated in multiple in vivo and in vitro short-term tests preparatory to its potential wide use as a molluscicide in control of schistosomiasis. When tested in the rec assay in Bacillus subtilis, TBTO was not mutagenic and it did not induce reverse mutations in Klebsiella pneumoniae. Neither in the presence nor in the absecne of rat liver activation system did TBTO produce point mutations in Salmonella typhimurium strains TA1530, TA1535, TA1538, TA97, TA98 or TA100. TBTO was matagenic in strain TA100 in a fluctuation test, but only in the presence of rat liver S9 (Aroclor-induced). TBTO did not induce gene mutations in the yeast Schizosaccharomyces pombe, mitotic gene conversions in the yeast Saccharomyces cerevisiae, nor sister-chromatid exchange in Chinese hamster ovary cells in the presence or absence of rat or mouse liver S9. In the latter cells, structural chromosomal aberrations, endoreduplicated and polyploid cells were induced. TBTO did not induce gene mutations in V79 Chinese hamster cells (to 8-azaguanine-, ouabain- or 6-thioguanine-resistance) in the presence of a rat liver postmitochondrial fraction or in cell (hamster embryo cells and human and mouse epidermal keratinocyte)-mediated assays. In mouse lymphoma cells, TBTO did not induce 6-thioguanine- or BUdR-resistant mutations. As many tumour promoters inhibit metabolic cooperation between V79 Chinese hamster 6-thioguanine-resistant/-sensitive cells, TBTO was tested but showed no such activity. TBTO was examined for the induction of recessive lethal mutations in adult Berlin K male Drosophila melanogaster, either by feeding or by injection. Doses of 0.37 or 0.74 mM did not increase the number of X-linked recessive lethal mutations. An increased number of micronuclei was observed in the polychromatic erythrocytes of male BALB/c mice 48 h after a single oral dose of TBTO (60 mg/kg bw), while a lower dose (30 mg/kg bw) was ineffective. Neither of the two doses had induced micronuclei 30 h after treatment. The reproductive toxicity of TBTO was studied in NMRI mice. In a 10-day toxicity study, the LD50 and LD10 were 74 and 34 mg/kg bw, respectively. An increased frequency of cleft palates was seen in the fetuses of mice (compared with controls, 0.7%) treated orally during pregnancy with 11.7 mg/kg TBTO (7%), 23.4 mg/kg (24%) or 35 mg/kg (48%).(ABSTRACT TRUNCATED AT 400 WORDS)

The history, clinical signs and radiographic and ultrasonographic findings in 16 dogs with pancreatic neoplasia were reviewed retrospectively. Thirteen of the dogs had islet cell carcinoma compatible with insulinoma, one had a pancreatic adenocarcinoma and two had secondary invasion of the pancreas, one by a gastric carcinoma and one by an intestinal lymphoma. The clinical signs in the 13 dogs with insulinoma included collapse in 10 dogs, ataxia in seven, weakness in five, and seizures in two. Two of the 16 dogs had jaundice due to biliary obstruction by the primary tumour or metastases. The sensitivities for pancreatic neoplasia were three of 16 (19 per cent) for radiography and 12 of 16 (75 per cent) for ultrasonography; the sensitivities for metastasis were two of 11 (18 per cent) for radiography and six of 11 (55 per cent) for ultrasonography. Biliary obstruction was detected by ultrasonography in both affected dogs.

A horse with malignant lymphoma (histiolymphocytic) and cutaneous amyloidosis is described. The lymphoma involved the dura mater of the spinal cord and some of the peripheral lymph nodes. Multifocal amyloid deposits were present in the skin and subcutis of the ventral abdomen but not within the lymphoma cell infiltrates or in the viscera.

A two-year-old, neutered female cross-bred labrador had multiple cutaneous nodules, biopsies of which revealed pathological changes consistent with cutaneous histiocytosis. During a period of one month the dog developed multicentric lymphadenopathy, a retrobulbar mass and masses within the quadriceps and cervical muscles. Fine needle aspiration cytology of the cutaneous nodules and lymph nodes and histological examination of the cutaneous nodules and muscle masses suggested the presence of lymphoblastic lymphoma. A definitive diagnosis of CD8+ T cell lymphoma was achieved by immunophenotyping the tumour cells by flow cytometry.

Multiple skin nodules, with histological features of adnexal tumours consistent with trichoepithelioma, were observed on the head and trunk of Syrian hamsters. Skin biopsies from 20 hamsters from five different colonies were affected, and two of the affected hamsters also had lymphoma. Two owners reported that 16 of 70 hamsters and 50 of 100 hamsters in their colonies had similar skin lesions. These tumours have previously been associated in laboratory colonies with hamster polyomavirus (HaPV) infection. Examination of skin tissues by electron microscopy failed to reveal intranuclear virus particles. Using recombinant major capsid protein VP1 of HaPV, VP1-specific antibodies were detected in sera from 12 of 12 affected hamsters and in four of four unaffected in-contact hamsters, by ELISA. The ELISA data were verified by immunoblot analysis. Eleven of 13 serum samples contained antibodies which reacted with at least one recombinant structural HaPV protein (VP2), including samples from three in-contact unaffected hamsters. Nine of the 11 anti-VP2-positive samples also reacted with recombinant VP3 of HaPV, and six reacted with VP1. Amplification by PCR and sequencing detected VP1 -encoding sequences showing a high degree of homology with HaPV. The findings suggest a possible infection by HaPV or a HaPV-like virus and it is likely that such an infection was enzootic within the affected colonies.
