Cytologic examination and viral and bacterial culture in herpes simplex, herpes zoster, and varicella.

Cytologic examination of epithelial cells from the base of vesicles, virus isolation, and bacterial culture were carried out in thirty-one patients with herpes simplex, in eleven patients with herpes zoster, and in three patients with varicella. Determination of herpes simplex complement fixation reaction was made in the patients with herpes simplex. Cytologic manifestations consistent with herpes were found 65 percent of patients with herpes simplex, while herpesvirus hominis was isolated in 77 percent of these patients. Diagnostic cytologic manifestations were found in 82 percent of the patients with herpes zoster or varicella. Varicella-zoster virus was isolated in 27 percent of these patients. The presence of pathogenic bacteria did not seem to influence the frequency of virus isolation or finding of characteristic cytologic features.

Double blind trial in the treatment of herpes simplex and herpes zoster with adenine arabinoside and idoxuridine.

In a double blind trial adenine arabinoside (Vidarabine) and Idoxuridine (IDU) were tested in herpes simplex and herpes zoster infections. Adenine arabinoside covered 19 patients with HSV and 6 with HZ while IDU 19 with HSV and 6 with HZ. From the statistical analysis it was found that Vidarabine acts shorter than IDU in HSV P less than 0.01, while in HZ no significant difference P less than 0.5 was found, possibly due to the small number of patients tested.

Herpes simplex virus glycoproteins: participation of individual herpes simplex virus type 1 glycoprotein antigens in immunocytolysis and their correlation with previously identified glycopolypeptides.

Tissue culture cells infected with herpes simplex type 1 virus express virus-specified glycoprotein antigens on the plasma membrane. Three of these have been previously identified and have been designated as Ag-11, Ag-8, and Ag-6. In the present study, immunoglobulins to each of the antigens were shown to be capable of mediating immunocytolysis in the presence of either complement (antibody-dependent complement-mediated cytotoxicity) or peripheral blood mononuclear cells (antibody-dependent cell-mediated cytotoxicity [ADCC]). Two herpes simplex virus type 1 strains, VR-3 and F, reacted similarly in the ADCC test in the presence of immunoglobulins to Ag-11, Ag-8, and Ag-6 in both infected Chang liver cells and HEp-2 cells. Anti-Ag-6, however, produced a lower ADCC reaction in HEp-2 cells than in Chang liver cells, suggesting differences in the Ag-6 surface expression in, or release from, these cells. Chang liver and HEp-2 cells infected with the MP mutant strain of herpes simplex virus type 1 showed reduced ADCC in the presence of anti-Ag-11 and anti-Ag-8, but no reactivity at all with anti-Ag-6. Crossed immunoelectrophoretic analysis showed that MP-infected cell extracts contain Ag-11 and Ag-8, but lack Ag-6. Polypeptide analysis of herpes simplex virus type 1 strains F, VR-3, and MP showed that Ag-11 consists of the glycoproteins gA and gB, that Ag-8 consists of gD, and that Ag-6 consists of gC. In conclusion, the present study demonstrates that either one of the glycoproteins (gC, gD, and a mixture of gA and gB) can function as a target for immunocytolysis and that the antibody preparation to gC (Ag-6) does not cross-react with any of the other glycoproteins.

The interaction of Herpes Simplex Virus with murine lymphocytes. I. Mitogenic properties of herpes simplex virus.

Herpes simplex virus (HSV) stimulates DNA synthesis in mouse spleen cultures prepared from normal, macrophage-depleted, and T-cell-depleted spleen cells, but not from thymocytes. In addition, a polyclonal antibody response is observed in HSV-infected spleen cultures. These findings indicate that the cells stimulated to undergo DNA synthesis after HSV infection appear to be the bone marrow-derived lymphocytes. The newly synthesized DNA is host cell and not of viral origin. Heat treatment and ultraviolet irradiation of HSV before addition to spleen cultures prevents the induction of DNA synthesis. We consider the use of this system as assay for the study of cell transformation by HSV and also for the study of host cell control of the expression of the viral genome.

Herpes simplex encephalitis: an autopsy case with isolation of type 1 herpes simplex virus.

An adult case of herpes simplex encephalitis was studied after autopsy. Postmortem examination revealed necrotizing encephalitis associated with Cowdry type A intranuclear inclusion bodies in glial cells. Herper simplex virus type 1 was isolated from the removed brain. Herpes simplex virus antigens were detected diffusely in wide areas of the brain by immunofluorescent test and viral particles characteristic to herpes simplex virus were demonstrated by electron microscopy. There was an apparent discrepancy between severity of histological changes and distribution of virus antigen.

Mapping of the herpes simplex virus DNA sequences in three herpes simplex virus thymidine kinase-transformed cell lines.

We have made use of a novel filter hybridization approach in order to map the herpes simplex virus (HSV) DNA sequences which are present in three HSV thymidine kinase (TK)-transformed cell lines. The cell line 33A+ which was produced by infection of 3T3 TK- cells with UV-irradiated HSV-2 (333) was found to contain one contiguous stretch of viral DNA sequences which maps between 0.15 and 0.57 on the HSV-2 genome. The sequences mapping from 0.31 to 0.37 were present in 3--4-fold higher abundance than the rest of the viral DNA sequences in this cell line. Cell lines 5A and 8N were produced by transfection of mouse CL1D cells with sheared HSV-1 (1023) DNA. The cell line 5A was found to contain a contiguous set of viral DNA sequences mapping between 0.26 and 0.41 on the HSV-1 genome. The cell line 8N was found to contain three non-contiguous sets of viral DNA sequences, mapping between 0.09 and 0.41, 0.53 and 0.58, and 0.94 and 1.0 on the HSV-1 genome. These results seem to indicate that many different sets of viral DNA sequences can be incorporated into the cell during HSV-mediated biochemical transformation.

Protective effect of an oral infection with herpes simplex virus type 1 against subsequent genital infection with herpes simplex virus type 2.

The problem of whether oral Herpes simplex virus type 1 (HSV-1) infection provides protection against subsequent genital infection by Herpes simplex virus type 2 (HSV-2) was investigated. Mice were used as models. Following conditions in man, both the oral and genital infections applied were noninjurious. Mice infected orally with HSV-1 were weakly protected against virus 'take' following vaginal challenge with HSV-2. Genital 'takes' were found in 67% of the immunized mice, as compared with 83% of the controls (protection rate 20%, P = 0.002). The course of genital infection in the immunized mice, however, was relatively mild: Lethality decreased from 97% in the controls to 35% in the immunized mice (protection rate 63%, P less than 0.001). Furthermore, local and neurologic symptoms occurred less frequently. Attempts to isolate the virus from homogenized brain and spinal cord of immunized mice that died after genital challenge with HSV-2 failed in most cases. Also virus could not be recovered from the liver of infected mice, irrespective of the experimental group.

Identification of a common antigen of herpes simplex virus bovine herpes mammillitis virus, and B virus.

In immunoelectrophoretic analyses one common antigen was demonstrated in antigen preparations from herpes simplex virus types 1- and 2- (HSV-1 and HSV-2), bovine herpes mammillitis (BHM) virus-, and B virus-infected cells solubilized by Triton X-100. The antigen was also demonstrated in solubilized purified HSV-1 and BHM virus. The common antigen was identified as antigen 11 of HSV-1 or HSV-2. Differences were found in the polypeptide composition of the related antigens when isolated from the four different herpesviruses, but a glycopolypeptide with a molecular weight of 125,000 was present in each of the four different antigen preparations, indicating that this polypeptide carried the common antigenic determinants.

Expression of an early, nonstructural antigen of herpes simplex virus in cell transformed in vitro by herpes simplex virus.

Hyperimmune rabbit antiserum to an early, nonstructural herpes simplex virus type 2 (HSV-2)-induced polypeptide (VP143) reacted in immunofluorescence tests with a variety of cell lines transformed by HSV-2. Cytoplasmic fluorescence was observed in 10 to 50% of HSV-2-transformed cells, whereas no fluorescence was observed in cells transformed by other oncogenic DNA viruses or by a chemical carcinogen. VP143-specific reactivity could be absorbed from anti-VP143 serum with HSV-2-transformed cells but not with cells transformed by other agents. When HSV-2-transformed cells were synchronized in mitosis and examined at various times postmitosis for VP143-specific fluorescence, the expression of VP143 was shown to be cell cycle dependent.

Effect of actinomycin D on the expression of herpes simplex virus-common surface antigen in cells transformed by herpes simplex virus type 2.

Using rabbit antiserum hyperimmune to herpes simplex virus (HSV) type 1, the expression of HSV-common surface antigen(s) was studied by indirect immunofluorescence tests in cells transformed by HSV type 2 and in derived tumor cells. The following results were obtained. (i) Antiserum to HSV type 1 reacted specifically with surface antigen present on the plasma membrane of both HSV type 2-infected and HSV type 2-transformed hamster cells. (ii) The expression of this antigen was enhanced in the absence of active protein synthesis in transformed cells, but not in tumor cells, after culture for 3 to 5 h at 37 degrees C. (iii) This enhancement of expression was maintained for 20 h in the presence of actinomycin D, but this prolonged expression required active protein synthesis. (iv) The enhancing effect observed in the presence of actinomycin D continued for some time after removal of the drug, for example, for 20 h after 5 h of treatment with 2 microgram/ml of actinomycin D per ml. Actinomycin D had no detectable effect on antigen expression in tumor cells. (v) The protease inhibitor antipain inhibited the actinomycin D-enhanced expression without causing significant cell damage but did not modify the transient enhanced expression of antigen when cells were seeded in the absence of actinomycin D. These results indicate that in transformed cells antigen expression can be enhanced in at least two ways.

Anal infections caused by herpes simplex virus.

Herpes simplex infections of the perianal skin and anal canal are not uncommon, as evidenced by the present series of 16 cases, but have rarely been reported in the literature of the past. They are caused by the HSV-2 virus, which is also associated with genital lesions. There is abundant evidence that anogenital herpes is a venereal disease. Anal herpes is most commonly transmitted by anal intercourse. When the infection is present inside the anal canal, especially in a primary attack, the pain can be quite dibilitating. The diagnosis can usually be made on clinical grounds by recognizing the typical vesicles or aphthous ulcers, together with inguinal lymphadenopathy. The disease is self-limiting, but may be recurrent. Asymptomatic homosexuals may represent a large reservoir of the disease, which appears to be on the increase in our society. Cytology, immunofluorescence, viral cultures and serologic tests can be used for laboratory confirmation of the diagnosis. Newer methods of treatment with vaccine containing heat-inactivated virus, and use of photoinactivation following topical application of heterotricyclic dyes, show promise.

Necrotizing encephalitis in skunks caused by Herpes simplex virus.

Herpes simplex virus was isolated from the brain of a wild skunk (Mephitis mephitis) which had clinical neurological disease. In the brain of this skunk and in brain of skunks inoculated intracerebrally, there were areas of necrosis in the grey matter of the cerebral cortex and to a lesser extent in the brain stem. Intranuclear inclusions occurred in neurons and glial cells with vascular cuffing by mononuclear cells and a few neutrophils. Skunks inoculated intravenously had extensive focal necrosis in the liver and adrenal glands.

Persistent infection of human lymphoid and myeloid cell lines with herpes simplex virus.

Herpes simplex virus (HSV) type 1 replicated and persisted in human T, B, and myeloid cell lines with different patterns of viral replication and various effects on cell growth. T cell line CEM supported the replication of HSV for over 400 days without detectable differences in cell growth as compared with uninfected cells. HSV persisted in B cell line NC37 and myeloid cell line K562 for up to 222 and 374 days, respectively, but led to a significant decrease in the number of viable cells by 7 weeks of infection. The average number of cells producing infectious virus was very low in these cell lines (range, 0.5 to 2.7+) compared with a larger proportion of cells exhibiting HSV antigens by immunofluorescence (range, 24 to 58%). In contrast, null cell line LAZ 221 failed to replicate HSV even though the viral infection led to a cessation of cell growth.

Efficacy of herpes simplex virus type 1 immunization in protecting against acute and latent infection by herpes simplex virus type 2 in mice.

ICR mice were immunized with herpes simplex virus type 1 (HSV-1) and later challenged with HSV-2 by footpad inoculation. Both immunized animals and age-matched, nonimmunized controls were observed for ascending neurological disease and latent infection of spinal ganglia resulting from the HSV-2 challenge. Control animals had a 78% incidence of acute and latent infection compared with a 1.7% incidence in immunized mice. The data show immunity to HSV-1 is protective against both acute and latent infection by HSV-2.
