Abstract
Herpes simplex virus type-1 (HSV-1) can cause severe ocular infection and blindness. We have previously shown that the HSV-1 VC2 vaccine strain is protective in mice and guinea pigs against genital herpes infection following vaginal challenge with HSV-1 or HSV-2. In this study, we evaluated the efficacy of VC2 intramuscular vaccination in mice against herpetic keratitis following ocular challenge with lethal human clinical strain HSV-1(McKrae). VC2 vaccination in mice produced superior protection and morbidity control in comparison to its parental strain HSV-1(F). Specifically, after HSV-1(McKrae) ocular challenge, all VC2 vaccinated- mice survived, while 30% of the HSV-1(F)- vaccinated and 100% of the mock-vaccinated mice died post challenge. VC2-vaccinated mice did not exhibit any symptoms of ocular infection and completely recovered from initial conjunctivitis. In contrast, HSV-1(F)-vaccinated mice developed time-dependent progressive keratitis characterized by corneal opacification, while mock-vaccinated animals exhibited more severe stromal keratitis characterized by immune cell infiltration and neovascularization in corneal stroma with corneal opacification. Cornea in VC2-immunized mice exhibited significantly increased infiltration of CD3+ T lymphocytes and decreased infiltration of Iba1+ macrophages in comparison to mock- or HSV-1(F)-vaccinated groups. VC2 immunization produced higher virus neutralization titers than HSV-1(F) post challenge. Furthermore, VC-vaccination significantly increased the CD4 T central memory (TCM) subsets and CD8 T effector memory (TEM) subsets in the draining lymph nodes following ocular HSV-1 (McKrae) challenge, then mock- or HSV-1(F)-vaccination. These results indicate that VC2 vaccination produces a protective immune response at the site of challenge to protect against HSV-1-induced ocular pathogenesis.

Abstract
Herpes Simplex Virus Type 2 (HSV-2) is one of the most prevalent sexually transmitted viruses and is a known risk factor for HIV acquisition in the Female Genital Tract (FGT). Previously, we found that curcumin can block HSV-2 infection and abrogate the production of inflammatory cytokines and chemokines by genital epithelial cells in vitro. In this study, we investigated whether curcumin, encapsulated in nanoparticles and delivered by various in vivo routes, could minimize inflammation and prevent or reduce HSV-2 infection in the FGT. Female mice were pre-treated with curcumin nanoparticles through oral, intraperitoneal and intravaginal routes, and then exposed intravaginally to the tissue inflammation stimulant CpG-oligodeoxynucleotide (ODN). Local intravaginal delivery of curcumin nanoparticles, but not intraperitoneal or oral delivery, reduced CpG-mediated inflammatory histopathology and decreased production of pro-inflammatory cytokines Interleukin (IL)-6, Tumor Necrosis Factor Alpha (TNF-α) and Monocyte Chemoattractant Protein-1 (MCP-1) in the FGT. However, curcumin nanoparticles did not demonstrate anti-viral activity nor reduce tissue pathology when administered prior to intravaginal HSV-2 infection. In an alternative approach, intravaginal pre-treatment with crude curcumin or solid dispersion formulations of curcumin demonstrated increased survival and delayed pathology following HSV-2 infection. Our results suggest that curcumin nanoparticle delivery in the vaginal tract could reduce local tissue inflammation. The anti-inflammatory properties of curcumin delivered to the vaginal tract could potentially reduce the severity of HSV-2 infection and decrease the risk of HIV acquisition in the FGT of women.

Abstract
Complete genome sequences of 19 strains of monkey B virus (Macacine alphaherpesvirus 1; BV) isolated from several macaque species were determined. A low level of sequence variation was present among BV isolates from rhesus macaques. Most variation among BV strains isolated from rhesus macaques was located in regions of repetitive or quasi-repetitive sequence. Variation in coding sequences (polypeptides and miRNAs) was minor compared to regions of non-coding sequences. Non-coding sequences in the long and short repeat regions of the genome did however exhibit islands of conserved sequence. Oral and genital isolates from a single monkey were identical in sequence and varied only in the number of iterations of repeat units in several areas of repeats. Sequence variation between BV isolates from different macaque species (different BV genotypes) was much greater and was spread across the entire genome, confirming the existence of different genotypes of BV in different macaque species.

Abstract
A chronic ulcerative and eosinophilic dermatitis occurred in 20 captive cheetahs ( Acinonyx jubatus) with persistent feline herpes virus 1 (FHV1) infection. Affected animals had erythematous, ulcerated plaques primarily on the face and forelegs in sites of contact with lachrymal and salivary secretions. The dermatitis was characterized by dense infiltrates of eosinophils and plasma cells and pseudoepitheliomatous hyperplasia. Rare keratinocytes within the lesions had nuclei with marginated chromatin and small eosinophilic inclusions composed of herpes virus nucleocapsids. Virus isolated from lesions was confirmed to be FHV1. Lesions persisted and progressed unless removed by cryoexcision. The occurrence of this unusual reaction to FHV1 in approximately 5% of captive North American cheetahs suggests a species propensity for a Th2-dominant response to herpes virus infection. This atypical immune reaction may indicate a heritable trait or modulation of the immune response by other factors such as chronic stress.

Abstract
In 2007, we detected human herpes simplex virus type 1, which caused stomatitis, in a juvenile confiscated eastern lowland gorilla (Gorilla beringei graueri) that had a high degree of direct contact with human caretakers. Our findings confirm that pathogens can transfer between nonhuman primate hosts and humans.

Abstract
The ongoing global spread of "exotic" farm animals, such as water buffaloes, which carry their native sets of viruses, may bear unknown risks for the animals, into whose ecological niches the former are introduced and vice versa. Here, we report on the occurrence of malignant catarrhal fever (MCF) on Swiss farms, where "exotic" water buffaloes were kept together with "native" animals, i.e. cattle, sheep, and goats. In the first farm with 56 water buffaloes, eight cases of MCF due to ovine herpesvirus-2 (OvHV-2) were noted, whereas additional ten water buffaloes were subclinically infected with either OvHV-2 or caprine herpesvirus-2 (CpHV-2). On the second farm, 13 water buffaloes were infected with CpHV-2 and two of those succumbed to MCF. In neither farm, any of the two viruses were detected in cattle, but the Macaviruses were present at high prevalence among their original host species, sheep and goats, respectively. On the third farm, sheep were kept well separated from water buffaloes and OvHV-2 was not transmitted to the buffaloes, despite of high prevalence of the virus among the sheep. Macavirus DNA was frequently detected in the nasal secretions of virus-positive animals and in one instance OvHV-2 was transmitted vertically to an unborn water buffalo calf. Thus, water buffaloes seem to be more susceptible than cattle to infection with either Macavirus; however, MCF did not develop as frequently. Therefore, water buffaloes seem to represent an interesting intermediate-type host for Macaviruses. Consequently, water buffaloes in their native, tropic environments may be vulnerable and endangered to viruses that originate from seemingly healthy, imported sheep and goats.

Abstract
Herpes simplex virus type 1 (HSV1) is widely used as a gene delivery vector in a variety of laboratory animals. In a recent study, a thymidine-kinase-inactive (replication-conditional) HSV1 used as a delivery vector was lethal in naked mole rats, whereas mice infected with the identical virus showed no adverse effects. This result prompted us to undertake a controlled comparative histologic study of the effect of HSV1 infection on naked mole rats and mice. Replication-competent and replication-conditional HSV1 caused widespread inflammation and necrosis in multiple organ systems of naked mole rats but not mice; naked mole rats infected with replication-defective virus showed no adverse effects. We conclude that the lethality of HSV1 for naked mole rats is likely the result of overwhelming infection, possibly in part due to this species' natural lack of proinflammatory neuropeptides at the initial site of infection.

Abstract
A bottlenose dolphin, stranded in the Canary Islands in 2001 exhibited non-suppurative encephalitis. No molecular detection of cetacean morbillivirus (CeMV) was found, but a herpesviral-specific band of 250 bp was detected in the lung and brain. The sequenced herpesviral PCR product was compared with GenBank sequences, obtaining 98% homology (p-distance of 0.02) with Human herpesvirus 1 (herpes simplex virus 1 or HSV-1). This is the first report of a herpes simplex-like infection in a stranded dolphin.

Abstract
With the emergence of the AIDS epidemic over the last 2 decades and the more recent identification of Kaposi sarcoma-associated herpesvirus (KSHV, Human herpesvirus 8), the genera of rhadinoviruses have gained importance as a family of viruses with oncogenic potential. First recognized in New World primates more than 30 y ago, the rhadinoviruses Saimiriine herpesvirus 2 and Ateline herpesvirus 2 have well-described transforming capabilities. Recently several new species-specific rhadinoviruses of Old World primates have been described, including retroperitoneal fibromatosis herpesvirus and rhesus rhadinovirus (Cercopithecine herpesvirus 17). Molecular analysis of these viruses has elucidated several functionally conserved genes and properties shared with KSHV involved in cellular proliferation, transformation, and immune evasion that facilitate the oncogenic potential of these viruses. This review examines the comparative pathobiology of KSHV, discusses the role of macaque rhadinoviruses as models of human disease, and outlines the derivation of specific pathogen-free animals.

Abstract
A juvenile orangutan (Pongo pygmaeus pygmaeus) died after 8 days of diarrhea and vomiting. Necropsy showed petechial hemorrhages in the skin, the myocardium, and the peritoneal membranes. The lungs were hyperemic and edematous, and the liver and spleen were enlarged. Histologic changes consisted of interstitial pneumonia, hepatitis, and splenic hyperplasia. Numerous eosinophilic intranuclear inclusion bodies were visible in pulmonary epithelial cells, hepatocytes, and splenic endothelial cells. Electron microscopic examination revealed herpesvirus in hepatocyte nuclei. Polymerase chain reaction of liver tissue demonstrated the presence of a herpes simplex virus-1.

Abstract
This report documents a case of spontaneous, fatal, and likely recrudescent human herpesvirus type 1 (HHV-1) infection in a captive white-handed gibbon (Hylobates lar) confirmed by polymerase chain reaction (PCR). An approximately 44-year-old, captive, female, white-handed gibbon with a history of recurrent conjunctivitis and occasional seizures became acutely weak, disoriented, and ataxic. A postictal state was suspected by caretakers and veterinary staff, and euthanasia was ultimately elected because of lack of clinical improvement with supportive care. No significant abnormalities were detected at necropsy. Histologically, sections of cerebrum and midbrain contained minimal to mild, multifocal lymphoplasmacytic meningoencephalitis with numerous intranuclear viral inclusions within astrocytes and some neurons. The presumptive diagnosis of HHV-1-induced encephalitis was strengthened by nested PCR amplification of a segment of the herpesvirus DNA polymerase gene. Sequences from this region have been found to be unique to each herpesvirus species, thus identifying HHV-1 as the likely etiologic agent in this case. Positive HHV-1 serology from several years before the terminal episode suggested that the disease was most likely due to recrudescence of latent HHV-1 infection.

Abstract
Here we describe the unusual finding of herpesvirus pneumonia in a 7-d-old infant baboon (Papio hamadryas anubis). This animal had been separated from its dam the morning of its birth and was being hand-reared for inclusion in a specific pathogen-free colony. The baboon was presented for anorexia and depression of 2 d duration. Physical examination revealed a slightly decreased body temperature, lethargy, and dyspnea. The baboon was placed on a warm-water blanket and was given amoxicillin-clavulanate orally and fluids subcutaneously. The animal's clinical condition continued to deteriorate despite tube feeding, subcutaneous fluid administration, and antibiotic therapy, and it died 2 d later. Gross necropsy revealed a thin carcass and severe bilateral diffuse pulmonary consolidation. Histopathology of the lung revealed severe diffuse necrotizing pneumonia. Numerous epithelial and endothelial cells contained prominent intranuclear herpetic inclusion bodies. Virus isolated from lung tissue in cell culture was suspected to be Herpesvirus papio 2 (HVP2) in light of the viral cytopathic effect. Real-time polymerase chain reaction (PCR) analysis and DNA sequencing of PCR products both confirmed that the virus was HVP2. This case is interesting because the age at onset suggests perinatal transmission at or immediately after birth, and the disease course suggests inoculation of the virus into the respiratory tract.

Abstract
An outbreak of herpesvirus caused the death of four of five common marmosets (Callithrix jacchus) in a private colony. Gross lesions included acute ulcerative gingivitis, glossitis, and enlarged mandibular lymph nodes. Histologically, all fatal cases showed meningoencephalitis and eosinophilia with intranuclear inclusion bodies in neurons and glial cells. A herpes simplex-like virus was cultured from the brain and was identified as herpes simplex type 1 virus or a closely related virus by immunofluorescence. Serologic testing (complement fixation test) indicated that the surviving adult female was serologically positive for more than 4 yr and that the offspring she produced was seronegative. The most likely source of the outbreak was the owner who mouth fed hand-raised offspring.

Abstract
Seroepidemiological surveys were performed on neutralizing antibody to bovine herpesvirus 2 (BoHV-2) among cattle in Japan. A total of 1,819 sera were collected from cattle in 27 prefectures from 1997 to 1998. Antibodies were detected in only 18 sera collected from 4 prefectures. However, the most prevalent areas of the infection were found in two islands located in the subtropical zone. Additional 353 sera were collected in three including these islands in 1999-2001. The antibody-positive rates in the farms in these islands ranged from 10% to 81.1%. It was confirmed that BoHV-2 was prevalent in these areas. However, the infection seemed to be latent, because no diseases have been noticed. This is the first report showing the presence of BoHV-2 infection among cattle in Japan.

Abstract
An outbreak of classical herpetic infection causing vesicoulcerative stomatitis in a family group (eight animals) of Callithrix jacchus is described. In all eight infected animals, human herpesvirus 1 (HHV-1) was identified as the causative agent. This was confirmed by histologic, immunohistologic, and molecular biologic investigations, as well as by virus isolation. The clinical picture, the macroscopic appearance, and the histologic results indicated a herpes infection as the cause of mortality. Alterations of the oral mucous membranes were erosive to ulcerative with typical intranuclear inclusions. Immunohistologic and molecular biologic techniques clearly identified the HHV-1 virus and excluded other possible primate herpesviruses such as B-virus, SA8, HVP-2, and Herpes tamarinus. The significance of this herpesvirus infection for colony management is discussed.

Abstract
Phocid herpesvirus type 1 (PhHV-1) is an alpha-herpesvirus that causes significant morbidity and mortality among young and immunocompromised harbour seals (Phoca vitulina) and therefore represents a major problem for seal rehabilitation centres. Consequently, there is a need for a safe and effective PhHV-1 vaccine. We tested an ISCOM-based recombinant PhHV-1 gB vaccine alone (gB) or with the addition of recombinant PhHV-1 gD (gBD) for (i). immunogenicity and protective efficacy against feline herpesvirus (FHV) infection in cats and (ii). their immunogenicity in seals. The FHV-cat model was chosen based on the close antigenic relationship between PhHV-1 and FHV. Upon challenge, all vaccinated (gB and gBD) cats excreted significantly less FHV (P<0.01) and gBD vaccinated cats showed less weight loss (P=0.05) than the mock-vaccinated cats. However, adding gD to the gB vaccine did not result in significantly better protection. Based on these data, immunogenicity studies in seals under rehabilitation were performed with the gB vaccine only. To this end, gB vaccine was tested at two different doses (20 or 40 microg). PhHV-1 specific antibody titres and in vitro proliferative T cell responses were measured in all seals upon vaccination. No differences were observed in antibody titres between seals vaccinated with either 20 or 40 microgB, but the higher gB concentration did result in higher specific proliferative T cell responses (P<0.01). Based on the close antigenic relationship between PhHV-1 and FHV, the safety and efficacy data in the FHV-cat model, and the immunogenicity data in the vaccinated seals, the gB based vaccine is expected to be safe and effective in protecting against PhHV-1 related disease in harbour seals.

Abstract
Beef cattle from a herd in north Alabama were examined because of an outbreak of nonfatal skin disease characterized by discrete circumscribed areas of inflammation that developed on the skin from the neck to the hips. Areas of inflammation, which tended to be superficial, underwent necrosis and scabbed over. The scabs eventually dropped off leaving discrete, round, whitish, hairless lesions that were 1.2 to 2.5 cm diameter. Because clinical signs were consistent with those expected with pseudo-lumpy skin disease (PLSD) caused by bovine herpesvirus type 2 (BHV-2), samples from 16 representative animals were submitted for BHV-2 testing. All 16 animals were seropositive for BHV-2, but the virus could not be isolated from skin biopsy specimens or buffy coat samples. Results of a polymerase chain reaction assay incorporating primers designed to amplify 2 DNA sequences from BHV-2 were positive for 3 of the 10 cattle, suggesting that skin lesions in these cattle were a result of PLSD. Our findings suggest that PLSD may be more common and widespread in the United States than suggested by the frequency with which BHV-2 has been isolated from cattle with PLSD-like skin lesions.

Abstract
Malignant catarrhal fever (MCF. corrizza contagiosa) is an invariably fatal communicable disease in cattle, whose causative agent is the ovine herpes virus-2, or the alcelaphine herpes virus-1. In one feed-lot family farm, 34 calves out of 100 became ill at the rate of one to four calves per week, and all of them subsequently died over a period of 4 months. Most of the initial cases were manifested clinically as the head and eye form, but most of the entire clinical spectrum of forms (the respiratory, intestinal and nervous forms) characteristic for MCF were observed as this epidemic progressed. Very few calves died without showing any specific signs of MCF. Pathological examinations revealed characteristic obliterative arteriovasculitis in the brain of calves with nervous signs, typical of MCF. Polymerase chain reaction (PCR) testing revealed 100% homology between the 238 bp hemi-nested PCR fragment and the ovine herpes virus-2 sequences. Based on the clinical signs, epidemiological data, pathological, and histopathological findings, and the PCR results, it was concluded that MCF occurred on the farm. The fact that sheep and goats were housed in close proximity on the same farm reinforced this diagnosis.

Abstract
A multiplex polymerase chain reaction (PCR) method coupled with a restriction analysis of PCR products (PCR with restriction fragment length polymorphism) was developed for the simultaneous detection of bovine herpesvirus 1, bovine herpesvirus 2, and bovine herpesvirus 4 infections. The specificity, sensitivity, and practical diagnostic applicability of this method were evaluated. This assay may be also adapted to the diagnosis of suid herpesvirus 1 and equine herpesviruses 1 and 3 and could become a powerful diagnostic tool.

Abstract
The most common viral disease of cats worldwide is the infection with feline herpesvirus 1 (FeHV-1). This infection may be followed by Herpetic stromal keratitis (HSK), which is supposed to have an immunopathological basis. Experiments using herpes simplex viruses (HSV) in mouse models indicated that HSK may be treated by topical application of the interleukin 10 (IL-10) gene. The objective of this study was the construction of human herpes simplex virus type 1 (HSV-1)-based amplicon vectors expressing feline interleukin genes and delivery of these genes into cells of feline origin. HSV-1-based amplicon vectors encoding either the enhanced green fluorescent protein, the feline IL-6 or the feline IL-10 under control of the HSV-1 immediate-early 4/5 promotor were constructed, packaged into amplicon particles, transduced into feline cells, and tested for RNA synthesis and biological activity. Feline cells were successfully transduced by HSV-1-based amplicon particles and RNA specific for the transgene was detected already at 2h post transduction, with a maximum at 24h. The recombinant feline IL-10 was functionally active as demonstrated by the reduction of both IL-12 p40 and interferon-gamma-mRNA production in Pansorbin stimulated feline peripheral mononuclear cells. Similarly, the recombinant feline IL-6, which was secreted into the supernatant of transduced cells, was able to support the growth of the IL-6-dependent murine B cell hybridoma 7TD1. HSV-1-based amplicon particles are able to transduce cells of feline origin with genes encoding biologically functional feline IL-10 or IL-6. It will be of high interest to study the effects of these tools in vivo.

Abstract
An adult pygmy African hedgehog developed acute posterior paresis attributed to a prolapsed intervertebral disc diagnosed by C-T scan. Corticosteroid therapy resulted in prompt resolution of the ataxia, but 2 weeks later the animal became anorexic and died. Macroscopically, the liver was stippled with punctate off-white foci which were confirmed microscopically to be foci of necrosis. Numerous hepatocytes contained intranuclear inclusions and syncytial cell formation was also present. A herpes virus was isolated and identified by fluorescent antibody and polymerase chain reaction studies as herpesvirus simplex type 1. To our knowledge, this is the first report of herpes infection in the African hedgehog and the first time herpes simplex has been identified as a cause of disease in insectivores.

Abstract
A serological study was done to establish the occurrence and determine the prevalence of two important respiratory tract pathogens, bovine respiratory syncytial virus (BRSV) and bovine herpesvirus-4 (BHV-4), in cattle in Ethiopia. Prevalence rates for specific antibodies of 92.5% and 22.3% were recorded for BRSV and BHV-4, respectively. The presence of antibodies against these viruses in cattle from Ethiopia is recorded for the first time in this report. Our data suggests diseases caused by these viruses occur in Ethiopia but, perhaps because disease signs are not specific, they have not been recognized in the past.

Abstract
Bovine herpes mammillitis was diagnosed in a dairy herd with udder and teat skin lesions. Clinical symptoms seen in 6 cows consisted of round dry areas at the teats as well as large red and painful areas with crust formation at the teats, the teat basis and the udder. Diagnosis was verified by demonstrating numerous virus particles with the typical herpes structure and by BHV-2 serum neutralization test. Prevalence of BHV-2 in the herd was determined by using BHV-2 SNT at 7 occasions during a period of 15 months. The relatively low BHV-2 SNT-titres as well as the seasonal increase of BHV-2 titres and seroprevalence in the month of September were indicative of a chronic and latent BHV-2 infection in the herd.

Abstract
OBJECTIVE To evaluate duration of immunity in cats vaccinated with an inactivated vaccine of feline panleukopenia virus (FPV), feline herpesvirus (FHV), and feline calicivirus (FCV). ANIMALS 17 cats. PROCEDURE Immunity of 9 vaccinated and 8 unvaccinated cats (of an original 15 vaccinated and 17 unvaccinated cats) was challenged 7.5 years after vaccination. Specific-pathogen-free (SPF) cats were vaccinated at 8 and 12 weeks old and housed in isolation facilities. Offspring of vaccinated cats served as unvaccinated contact control cats. Virus neutralization tests were used to determine antibody titers yearly. Clinical responses were recorded, and titers were determined weekly after viral challenge. RESULTS Control cats remained free of antibodies against FPV, FHV, and FCV and did not have infection before viral challenge. Vaccinated cats had high FPV titers throughout the study and solid protection against virulent FPV 7.5 years after vaccination. Vaccinated cats were seropositive against FHV and FCV for 3 to 4 years after vaccination, with gradually declining titers. Vaccinated cats were protected partially against viral challenge with virulent FHV. Relative efficacy of the vaccine, on the basis of reduction of clinical signs of disease, was 52%. Results were similar after FCV challenge, with relative efficacy of 63%. Vaccination did not prevent local mild infection or shedding of FHV or FCV. CONCLUSIONS Duration of immunity after vaccination with an inactivated, adjuvanted vaccine was > 7 years. Protection against FPV was better than for FHV and FCV. CLINICAL IMPLICATIONS Persistence of antibody titers against all 3 viruses for > 3 years supports recommendations that cats may be revaccinated against FPV-FHV-FCV at 3-year intervals.

Abstract
Antibodies were detected against bovine herpesviruses 1 (BHV 1) and 2 (BHV 2) in Asian elephants (Elephas maximus) using the passive hemagglutination (PHA) test. The study was conducted during May to December 1994 using sera collected from zoological gardens and national parks in India. Four (4%) of 109 elephant sera had PHA titers ranging from 1:8 to 1:32 against BHV 1. Twenty-five (23%) of the 109 elephant sera had PHA titers ranging from 1:8 to 1:64 against BHV 2. Asian elephants appear to be better reservoirs for herpesviruses which are serologically related to BHV 2.

Abstract
OBJECTIVE To compare nested polymerase chain reaction (PCR), virus isolation (VI), and fluorescent antibody (FA) testing to detect feline herpesvirus (FHV) in cats with naturally acquired conjunctivitis or respiratory tract disease, or both. SAMPLES Swab and microbrush specimens from the conjunctiva and throat were taken from 46 cats, allotted to 3 groups (conjunctivitis only, respiratory tract disease and conjunctivitis, and clinically normal). PROCEDURE Cells from microbrush specimens were digested and herpesvirus DNA was amplified, using a double round of PCR. Products were detected by use of agarose gel electrophoresis. The VI and FA tests were performed in routine manner. RESULTS Of 16 cats with conjunctivitis only, conjunctival specimens from 8 and throat specimens from 8 were FHV positive by PCR. None had positive results of VI or FA testing. Of 15 cats with respiratory tract disease and conjunctivitis, conjunctival specimens from 13 and throat specimens from 12 were FHV positive by PCR. A conjunctival specimen from 1 cat and throat specimens from 3 cats were FHV positive by VI. A conjunctival specimen from 1 cat was FHV positive by FA testing. Of 15 clinically normal cats, conjunctival and throat specimens from 2 cats were FHV positive by PCR; neither conjunctival nor throat specimens from these cats were FHV positive by VI or FA testing. CONCLUSION For cats with respiratory tract disease and conjunctivitis, or with conjunctivitis only, nested PCR was more sensitive at detecting FHV than was VI or FA testing. CLINICAL RELEVANCE Nested PCR is a more sensitive test than the currently available VI and FA tests for identifying FHV in cats with conjunctivitis.

Abstract
An approximately 1-year-old domestic rabbit showed severe neurologic signs with circling and turning somersaults. Histologically, a nonsuppurative meningoencephalitis with neuronal cell necrosis and numerous intranuclear inclusion bodies in neurons and glial cells was found. Electron microscopic examination revealed herpesvirus particles in affected cells. A human herpes simplex virus was identified by means of immunocytochemistry and in situ hybridization as the causal agent and was further classified as herpes simplex virus 1 by polymerase chain reaction analysis. Because encephalitis is easily induced in rabbits by experimental infection with herpes simplex virus, the source of infection is suspected to be a human with herpes labialis who had close contact with the rabbit.

Abstract
We constructed a recombinant baculovirus expressing feline herpesvirus type I (FHV-1) gD in insect cells (Sf9 cells). The expressed product was identified as FHV-1 gD by a panel of monoclonal antibodies specific for the FHV-1 gD, and had an apparent molecular mass of approximately 49 kDa, which was less than that of the authentic FHV-1 gD. When the FHV-1 gD protein were expressed in Sf9 cells and CRFK cells in the presence of tunicamycin, the FHV-1 gD exhibited a molecular mass of 41 kDa. It was shown that the gD protein was transported to the surface of recombinant virus-infected Sf9 cells when examined by membrane-immunofluorescence analysis, and that the gD expressed on the surface of Sf9 cells adsorbed feline erythrocytes. Mice inoculated with a lysate of Sf9 cells expressing FHV-1 gD induced antibodies with virus-neutralizing and hemagglutination-inhibition activities. Therefore, the expressed gD appears to be biologically authentic. These data suggested that recombinant FHV-1 gD produced in Sf9 cells may be a useful immunogen as a feline vaccine.

Abstract
The thymidine kinase region of feline herpesvirus 1 (FHV 1) genome in ocular/nasal swabs from cats with clinical manifestations of upper respiratory disease was amplified by nested polymerase chain reaction (nested PCR). Two primer pairs were prepared for nested PCR. FHV 1 DNA in ocular/nasal swabs was extracted using instaGene-DNA purification matrix. Nested PCR for the FHV 1 culture supernatants was ten times as sensitive as single PCR. On comparing viral isolation with single PCR and nested PCR for the detection of FHV 1 in ocular/nasal secretions, of 5 samples that yielded infectious virus in cell culture, 3 (60%) were positive in single PCR and 5 (100%) were positive in nested PCR. When 22 ocular/nasal swabs that did not yield FHV 1 were assayed, 3 were negative in both single PCR and nested PCR, 2 were positive in both single and nested PCR and 17 were positive in only nested PCR. Thus, FHV 1 was detected in 19/22 (86.4%) by the nested PCR and in 2/22 (9%) by single PCR. These results show that nested PCR is 4.8 (24 positive samples/5 positive samples) times as sensitive as single PCR.

Abstract
This report describes a new technique for obtaining cerebrospinal fluid from the living mouse (SJL/NBom) in a model of herpes simplex virus encephalitis which is also applicable to other mouse models. The puncture technique was performed in living animals which had been infected with Herpes Simplex Virus Type I strain F in the living animal. The cisterna magna was micro-surgically prepared: The neck muscles were dissected microscopically down to the dura which subsequently was punctured by a glass micropipette. This newly developed minimally invasive technique was performed in a group of living animals (n = 20) and results compared with those of a second group of perfusion fixed animals (n = 20). For the first time, repeated cerebrospinal fluid punctures of individual, living animals are possible. This is of great value for the assessment of new therapeutic and diagnostic strategies in experimental research using mouse models. In addition, this refined methodology significantly reduces the number of experimental animals.

Abstract
The contagious coryza is an acute disease in cats, which is caused by feline calicivirus (FCV) and feline herpesvirus type-1 (FHV-1). FCV appears to be isolated more frequently from cats than FHV-1. This review summarizes the current knowledge about FCV and about the clinic, epidemiology, and pathogenesis of the disease induced. Particular problems of immunoprophylaxis of infection with FCV are also discussed.

Abstract
Bovine herpes mammillitis virus or bovine herpesvirus type 2 (BHV-2) causes ulcerative lesions on the teats and udders of infected cows. Since no commercial vaccine is available for this disease, we investigated certain experimental BHV-2 vaccines against this virus in infected guinea pigs. Vaginally infected guinea pigs get severe, self-limiting vaginal infections characterized by erythema and swelling and the production of measurable vaginal virus titers. Two vaccine approaches were investigated: vaccination with wild-type (WT) virus by the subcutaneous route, and vaccination either subcutaneously or intravaginally with a thymidine kinase (TK) deficient (TK-) virus. The TK- strain was prepared by passage of BHV-2 in the presence of the potent TK-dependent antiviral agent 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-methyluracil (FMAU). The antiviral activity of FMAU against the virus in plaque reduction assays changed from 0.05 to 2 microM at the same time that the TK activity of the mutant virus decrease to 7% of WT virus TK activity. Subcutaneous vaccination of guinea pigs with WT and TK- viruses did not induce vaginal infection. Primary vaginal infection (vaccination) with the TK- virus led to greatly reduced lesion severity compared to vaginal infection with the WT virus. However, the amount of vaginal virus titers recovered during these primary infections was similar for both TK- and WT viruses, indicating that both viruses had equal infecting potential. Thirty days after vaccination the animals were re-infected intravaginally with WT virus. The vaccinated animals showed dramatically reduced lesion severity and low recoverable virus titers compared to age-matched nonvaccinated animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Fifteen bovine herpesvirus-1 (BHV-1)-negative calves were vaccinated intramuscularly with 10(7.4) plaque-forming units of a double-deletion BHV-1 mutant (IBRV(NG)dltkdlgIII), and 6 remained as nonvaccinated controls. Thirty days after vaccination, the animals were challenged by nasal instillation of 10(8.2) CCID50 of a virulent BHV-1 strain (Cooper). The vaccinated calves were protected against wildtype virus challenge as demonstrated by clinical evaluation. Most of the vaccinates developed only a mild rhinitis (lasting an average of 6.5 days) with almost no systemic symptoms, whereas the controls developed a serious illness characterized by rhinitis (mean = 11.5 days), conjunctivitis, hyperthermia, apathy, loss of appetite, and dyspnea. The vaccinates also shed significantly less virus and for a shorter period of time (mean = 5.5 days) than the controls (mean = 9 days). Thirty days after vaccination, the vaccinates were negative in an anti-gIII specific blocking enzyme-linked immunosorbent assay (ELISA), despite the fact that most of them had developed neutralizing antibodies (serum neutralization titers ranging from 1:2 to 1:16). Seroconversion to gIII was detected as early as 7 days postinfection (dpi). Fourteen days after the challenge, all the animals exposed to wildtype BHV-1 had developed anti-gIII antibodies and were positive in this differential serologic test. Six controls plus 8 vaccinates kept in isolation were still positive to gIII when tested at 75 dpi. The use of the IBRV(NG)dltkdlgIII strain in conjunction with an anti-gIII specific blocking ELISA kit represents a powerful tool for BHV-1 control/eradication programs.

Abstract
Some SCID mice survived primary infection with herpes simplex virus 1 without the development of peripheral lesions but established coculture-positive ganglionic latency when a low dose of a wild-type strain was inoculated intracutaneously. The latency was also evidenced by the development of the fatal zosteriform skin lesions and the isolation of the virus during pregnancy. We consider that the viral entry into neurons without successive replication, rather than the arrest of the lytic infection within the cells, is an important mechanism in the establishment of latency.

Abstract
There are two traditional ways to modify a virus for immunization: (1) kill the virus or (2) use a live, attenuated virus. There are three modern ways to prepare vaccines: (1) extract and purify a part of the virus that is immunogenic, (2) synthesize a polypeptide immunogen piece of the virus, or (3) use recombinant deoxyribonucleic acid or gene splicing to prepare an immunogenic portion of the virus. The last three produce subunit vaccines that can be made to contain no deoxyribonucleic acid. They are not infectious and are likely to be nononcogenic. Using recombinant deoxyribonucleic acid techniques, a vaccine for bovine papillomavirus has been prepared. This is in clinical trials and probably will be licensed for use in cattle in 1988. A vaccine for herpes simplex virus has been prepared using glycoprotein D from the surface of the virus. This immunizes animals but it has not reached clinical trials in humans.

Abstract
Young male white Swiss mice were fed control diet or diet supplemented with 20 or 10 parts per million (ppm) of T-2 toxin for two or three weeks. These mice then were inoculated with herpes simplex virus type 1 (HSV-1) (9.6 x 10(6) plaque forming units) intraperitoneally. To compare the effects of T-2 toxin against a known immunosuppressive drug, cyclophosphamide was injected intraperitoneally at 150 mg/kg, 24 hours after treatment with HSV-1, into mice fed the control diet. Mice were necropsied and tissues were collected for microscopic and virologic examination. White Swiss mice which consumed a daily diet containing 20 ppm of T-2 toxin for two or three weeks were highly susceptible to HSV-1 infection and 27 of 36 (75%) died as a result of extensive hepatic and adrenal necrosis. Although HSV-1 was isolated from livers and brains of mice fed 20 ppm of T-2 toxin for two or three weeks, there was little or no inflammatory response found in the adrenals, livers, spinal cords, brains, or ganglia. The necrotizing encephalomyelitis observed in control mice was absent. High levels of dietary T-2 toxin appeared to be more immunosuppressive than cyclophosphamide because only one mouse died after treatment with HSV-1 and cyclophosphamide. Mice treated with cyclophosphamide had changes in brain, spinal cord, spleens, thymus, and bone marrow which were similar to those fed 20 ppm of T-2 toxin and infected with HSV-1, however, liver lesions were much less severe. HSV-1-infected mice on a diet with 10 ppm T-2 toxin had lesions of intermediate severity when compared with HSV-1-infected mice fed a diet with 20 ppm T-2 toxin and HSV-1-infected mice on control diets. Necrosis was less extensive in the livers and adrenals. The infrequent isolation of virus from liver and brain was consistent with the lack of intranuclear inclusion bodies and a more marked inflammatory response. Ten ppm of dietary T-2 toxin only depressed bone marrow and splenic red pulp to a mild or moderate degree. This may have enhanced the necrotizing encephalomyelitis observed in mice killed on days 6 and 8 after HSV-1 infection. Liver lesions were mild and those of the adrenals were moderate in mice fed control diet. The rare isolation of HSV-1 from the liver and brain and the findings of a moderate to severe necrotizing encephalomyelitis in these mice was consistent with an essentially functional immune system.
