Summary The major inverted repeat of 7319.5 base pairs is present at an internal site in the varicella-zoster virus genome and at one terminus. A DNA sequence of 7747 base pairs containing the repeat was determined and analysed. The G + C content of the repeat is not uniform, and is significantly higher than that of adjacent unique regions. The repeat contains a G + C-rich reiterated sequence, an A + T-rich sequence with the potential of forming a hairpin structure which may form part of an origin of DNA replication, and three open reading frames predicted to encode primary translation products with approximate molecular weights of 140 000, 30 000 and 20 000. The possibility is discussed that the expression of other open reading frames near the genome termini may depend upon genome conformation.

We describe three cases of patients with concomitant acute medullary or brainstem multiple sclerosis (MS) lesions and detectable spinal fluid varicella-zoster virus DNA. Herpes simplex virus PCR was also positive in two of the patients. One patient was re-punctured 2 weeks following the relapse, with negative results. The PCR findings greatly delayed correct diagnosis and treatment in all three patients. Based on our cases, we propose that inflammatory medullary and brainstem lesions could result in viral leakage, and possibly viral reactivation, from destroyed sensory neurons, yielding false-positive cerebrospinal fluid PCR results. As this can have diagnostic and therapeutic consequences, further studies are warranted to evaluate the clinical relevance of these findings.. Reference:. Torkildsen Ø, Power Ø, Storstein A.

More than 500 hospital employees and 209 patients were exposed to varicella zoster virus (VZV) as a consequence of 22 uncontrolled hospital introductions that occurred over a period of 34 months. Five introductions of varicella were by hospital employees who acquired the infection outside the hospital. Successful infection control of VZV requires an accurate definition of the susceptible population and the limitation of transmission. Individuals with prior VZV infection are epidemiologically not at risk for developing clinical illness. Serologic screening of hospital employees with uncertain prior VZV history is effective in identifying those at risk of developing the infection. A prior history of intimate exposure to VZV does not imply immunity in the absence of clinical illness.. ...

Humoral and cellular immune responses to whole varicella-zoster virus (VZV) antigen and the VZV proteins glycoprotein I (gpI) and nonglycosylated protein p170 were evaluated in healthy children and adults given lyophilized live-attenuated varicella vaccine. Children received one dose of vaccine containing 950 pfu, whereas adults received two doses of 2500 pfu. After one year, the antibody titers of adult vaccinees to whole VZV and to gpI were significantly higher than those of children. Antibody titers to whole VZV, gpI, and p170 were lower among both vaccine populations than titers in naturally immune individuals, but vaccinees who seroconverted initially retained detectable VZV antibodies. Using T lymphocyte proliferation to measure cellular immunity, we found the mean (+/- SE) transformation index to whole VZV antigen to be 4.1 +/- 0.96 in children tested at one year, a mean significantly lower than the mean of 12.7 +/- 3.39 in adults and 13.0 +/- 1.67 in naturally immune subjects. These observations

Varicella zoster virus (VZV) is a highly neurotropic, exclusively human herpesvirus. Primary infection causes varicella (chickenpox), wherein VZV replicates in multiple organs, particularly the skin. Widespread infection in vivo is confirmed by the ability of VZV to kill tissue culture cells in vitro derived from any organ. After varicella, VZV becomes latent in ganglionic neurons along the entire neuraxis. During latency, virus DNA replication stops, transcription is restricted, and no progeny virions are produced, indicating a unique virus-cell (neuron) relationship. VZV reactivation produces zoster (shingles), often complicated by serious neurological and ocular disorders. The molecular trigger(s) for reactivation, and thus the identity of a potential target to prevent it, remains unknown due to an incomplete understanding of the VZV-neuron interaction. While no in vitro system has yet recapitulated the findings in latently infected ganglia, recent studies show that VZV infection of human neurons in

Several vaccinia virus (VV)-varicella-zoster virus (VZV) recombinants expressing glycoprotein I (gpI) of VZV were isolated from the Prague strain of VV. One of these, v46, was inoculated intraperitoneally into mice. Groups of mice were bled 4 and 8 weeks later and their sera were examined for anti-VZV and anti-VV antibodies by ELISA. At 4 weeks, all mice inoculated with the three largest virus doses (107, 106 and 105 p.f.u.), and at 8 weeks all mice inoculated with the four highest virus doses (107, 106, 105 and 104 p.f.u.), had developed both anti-VV and anti-VZV antibodies. Antibodies were also detected in a high proportion of mice infected with lower doses of virus and in some instances VZV antibodies were present in the absence of VV antibodies. None of the animals inoculated in parallel with either a thymidine kinase-negative mutant of the original VV or diluent alone developed antibody reactive with VZV. The specificity of the reaction was assessed further by Western blotting using anti-gpI

Cytomegalovirus (CMV), Epstein Barr virus (EBV) and varicella-zoster virus (VZV) are common herpesviruses frequently acquired in childhood, which establish persistent, latent infection and are likely to impact the developing immune system. Little is known about the epidemiology of CMV and EBV infections in contemporary UK paediatric populations, particularly whether age at infection differs by ethnic group. Children enrolled in the Born in Bradford Allergy and Infection Study had a blood sample taken and a questionnaire completed at 12 and 24 months of age. Ordered logistic regression quantified associations between ethnicity and other risk factors and age at CMV/EBV/VZV infection (|12 months, 12-24 months, uninfected at 24 months). Pakistani children (n = 472) were more likely to be infected with CMV and EBV at a younger age than White British children (n = 391) (CMV: adjusted odds ratio (OR) 2.53, 95% confidence interval (CI) 1.47-4.33; EBV: adjusted OR 2.16, 95% CI 1.43-3.26). Conversely, Pakistani

VZV gE is a multifunctional protein, involved in cell-cell fusion and cell-to-cell spread of viral particles and secondary envelopment of the cytoplasmic virions in the trans-Golgi network (9, 26, 27, 48). VZV gE has unique characteristics compared to gE in the other alphaherpesviruses. We have shown that, in contrast to these other viruses, VZV gE is required for VZV replication (25, 30) and that VZV gE has a nonconserved N-terminal region of the ectodomain that is essential for VZV replication (4). Importantly, specific VZV gE functional motifs are necessary for T-cell and skin tropisms involved in VZV pathogenesis (4, 31).. Given the importance of gE for VZV replication and pathogenesis, we investigated in detail the role of VZV transactivators and cellular transcriptional factors in the regulation of the VZV gE promoter in vitro and in vivo. We found that the major VZV transactivator, IE62 (38-40), is the viral regulatory protein with the most potent effect on the gE promoter compared to ...

Varicella zoster virus (VZV) typically causes chickenpox upon primary infection. In rare cases, VZV can give rise to life-threatening disease in otherwise healthy people, but the immunological basis for this remains unexplained. We report 4 cases of acute severe VZV infection affecting the central nervous system or the lungs in unrelated, otherwise healthy children who are heterozygous for rare missense mutations in POLR3A (one patient), POLR3C (one patient), or both (two patients). POLR3A and POLR3C encode subunits of RNA polymerase III. Leukocytes from all 4 patients tested exhibited poor IFN induction in response to synthetic or VZV-derived DNA. Moreover, leukocytes from 3 of the patients displayed defective IFN production upon VZV infection and reduced control of VZV replication. These phenotypes were rescued by transduction with relevant WT alleles. This work demonstrates that monogenic or digenic POLR3A and POLR3C deficiencies confer increased susceptibility to severe VZV disease in ...

Varicella-zoster virus (VZV) is the etiological agent of chickenpox and shingles. Due to the viruss restricted host and cell type tropism and the lack of tools for VZV proteomics, it is one of the least-characterized human herpesviruses. We generated 251 monoclonal antibodies (MAbs) against 59 of the 71 (83%) currently known unique VZV proteins to characterize VZV protein expression in vitro and in situ. Using this new set of MAbs, 44 viral proteins were detected by Western blotting (WB) and indirect immunofluorescence (IF); 13 were detected by WB only, and 2 were detected by IF only. A large proportion of viral proteins was analyzed for the first time in the context of virus infection. Our study revealed the subcellular localization of 46 proteins, 14 of which were analyzed in detail by confocal microscopy. Seven viral proteins were analyzed in time course experiments and showed a cascade-like temporal gene expression pattern similar to those of other herpesviruses. Furthermore, selected MAbs ...

1. ABSTRACT Varicella zoster virus (VZV) is the herpesvirus which causes the childhood disease varicella, also known as chickenpox, and the adult disease herpes zoster, also known as shingles. These distinct diseases are separated by a lengthy period of latency, often lasting decades, in which the virus resides within the ganglia of the host. VZV latency and reactivation from it have, for the most part, been extraordinarily difficult to examine. This is due to the lack of a good animal model for the VZV latent state, the inability to experimentally reactivate VZV under any circumstances and the caveats and problems encountered in examining human ganglionic tissue. However, insights into features of the molecular events of VZV latency have been gleaned from its pathogenesis and from recent advances in molecular probing of human and animal ganglia. Evidence suggests that the latent VZV genome may express transcripts unlike those of closely related herpesviruses, and some evidence suggests an ...

Purpose : VZV keratitis is generally accepted to be an immune response rather than an active viral infection. Consequently, current treatment paradigms generally recommend steroids rather than antiviral agents. The purpose of this investigation is to determine the prevalence of positive polymerase chain reaction (PCR) in suspected cases and to identify predictive or associated factors. Methods : In this retrospective analysis, we identified 22 patients who presented to Geisinger Eye Institute with a clinical diagnosis of acute VZV keratitis and who underwent corneal swab and PCR for VZV. Univariate analysis of eyes positive (group 1) and negative (group 2) for VZV was performed to identify differentiating factors. Results : All participants had a history of VZV rash and all but one had pseudodendrites at the time of swab. Thirteen of 22 eyes (59.1%) had positive PCR for VZV. Mean time between rash and first ocular sign was 1.39 months (range -1 to 6.75) in group 1 and 10.63 months (range 0.1 to ...

Our analysis of IFN-α and IL-1α in VZV-infected and uninfected skin xenografts revealed a subtle interaction between VZV and epidermal cell cytokine responses. Type I interferons, IFN-α, and to a lesser extent, IFN-β, are the predominant mediators of innate antiviral activity. Constitutive IFN-α/β expression occurs in some cells or tissues, allowing an immediate antiviral response (13). IFN-α/β activation is induced by the Jak/Stat pathway when ligands bind to IFN-α/β receptors and stimulate transcription of the IFN regulatory factors (IRFs) (8). IRF3 and IRF7 are crucial for maximal expression of IFN-α/β (14, 15). Constitutive IFN-α/β signaling is thought to sustain IRF7 expression and enhance IFN-α/β production in a positive feedback loop in response to viral infection (16). Most viruses have mechanisms to inhibit synthesis of IFNs or evade downstream antiviral effects in order to allow viral spread before adaptive immunity develops. HSV, a human alphaherpesvirus closely ...

Precipitin antigen was prepared from cultures infected with V-Z virus. Five separate antigens were identified. Reactions with radiolabeled antigen were detected by autoradiography. Partial purification of antigens could be accomplished in a discontinuous sucrose gradient, yet too little antigen was recovered from DEAE to make this a practicable purification method. Most of the antigenic activity was eluted from G-200 Sephadex. Antigens were identified by their degree of chemical stability. The α antigen was the only one which was stable at pH 3. The β antigen was destroyed by CsCl or DOC. DOC released the γ Δ, and ε antigens from the infectious viral particle.. ...

Shingles is a viral infection which is medically recognized as herpes zoster. The natural remedies for shingles can effectively treat this viral infection. The varicella zoster virus is considered to be responsible for causing this disease. Additionally, this same virus causes chicken pox. The medicines for chicken pox do not eliminate the virus completely causing herpes zoster lately. Moreover, the herpes zoster disease is a short lived but irritating disease, and often occurs many years after the initial infection. The natural remedies for shingles can help a person to relieve this irritating disease. The herpes zoster virus becomes latent in the body without causing symptoms for many years. Moreover, this virus may remain in the non-neuronal satellite cells of dorsal root, autonomic ganglion or cranial nerve of the body, and causes herpes zoster lately. The natural remedies for shingles are very helpful in treating the herpes zoster virus by relieving the symptoms of the disease.. The very ...

Varicella zoster virus (VZV) is a herpes virus that causes the chicken pox in children and shingles in adults. VZV first enters the body either through the respiratory tract or the eyes, and later infects the nervous system. Symptoms of fever and general discomfort are noticed between 10-21 days after initial exposure to the virus. A characteristic rash with red, spotted lesions will then appear in several stages, often spreading from the head downwards to the arms and legs. The rash will be more severe when seen in adults than in children.. Symptoms are most common in the winter and early spring. The disease may be spread through the air or by direct contact with infected individuals at any time until their rash has dried into crusted lesions. After symptoms clear, VZV remains inactive (latent) in nerves and results in lifetime immunity for most people. Reactivation later in life results in shingles (herpes zoster), which occurs in 50% of people by age 85. Shingles is most common in the elderly ...

Studies into the impact of vaccination against the varicella zoster virus (VZV) have increasingly focused on herpes zoster (HZ), which is believed to be increasing in vaccinated populations with decreasing infection pressure. This idea can be traced back to Hope-Simpsons hypothesis, in which a persons immune status determines the likelihood that he/she will develop HZ. Immunity decreases over time, and can be boosted by contact with a person experiencing varicella (exogenous boosting) or by a reactivation attempt of the virus (endogenous boosting). Here we use transmission models to estimate age-specific rates of reactivation and immune boosting, exogenous as well as endogenous, using zoster incidence data from the Netherlands (2002-2011, n=7026). The boosting and reactivation rates are estimated with splines, enabling these quantities to be optimally informed by the data. The analyses show that models with high levels of exogenous boosting and estimated or zero endogenous boosting, constant ...

The most striking finding of this study is the observation that VZV infection is associated with a 58-fold (95% CI: 40-85) increased risk of acquiring invasive GAS disease in children. It is not clear why chickenpox infection increases the risk for GAS infection so dramatically. One possibility is that invasive disease occurs as a consequence of the increased rate of superficial skin infection caused by the chickenpox lesions causing breakdown in the skin barrier. This is supported in part by the observation that the majority of chickenpox-associated infections occurring in this study had a soft tissue focus. However, the risk of invasive GAS infection at sites not directly related to skin was also increased, which suggests that other mechanisms predisposing to invasive infection are important. VZV infection itself may cause a predisposing immune aberration or may allow invasion via another less apparent portal, such as lesions on the oral mucosa or the respiratory tract. In favor of an immune ...

Simply put, Shingles is an attack on the bodys immune system. Shingles, also known as herpes zoster, is a viral infection that causes a painful skin rash which often include blisters. The blisters most commonly appear in a stripe like pattern, entering at the roots of nerves and follows them to the skin. Shingles is caused by a reactivation of the varicella zoster virus, also known as chicken pox. The chicken pox virus lies dormant for years, sometimes even decades, waiting to be reactivated. Approximately one in three Americans will experience Shingles in their lifetime. Typically, Shingles affect the elderly and the immunocompromised. As we age, our immune systems ability to fight off various illnesses naturally diminishes. Others who are fighting autoimmune disorders, being treated for cancer, or that have HIV are also at risk for developing the virus. Although rare, low risk healthy adults can develop shingles. Fortunately, they usually have an easier time recovering from the effects of ...

Shingles is a painful viral infection caused by the varicella zoster virus. This is the same virus that causes chicken pox. It isnt life threatening, but it does cause a painful rash. The shingles rash can appear anywhere on your body, but it usually appears as a band of blisters from the middle of your back around the side of the chest to the breastbone. Anyone who has had chicken pox can contract shingles. The virus lies inactive in nerve tissue near your spinal cord and brain. The virus may reactivate years later as shingles.. It is unknown why the virus is sometimes reactivated in the body. Experts believe that a weakened immune system could one explanation. As you grow older, your immune system becomes weaker. Shingles is more common in people over the age of 50. The risk also increases with age.. Shingles can also happen in younger people. This is more common when the immune system has been compromised by HIV/AIDS, cancer, cancer treatments, long use of steroids, or drugs that suppress ...

Now heres a kicker. The shingles vaccine contains live, weakened [attenuated] varicella -zoster virus. It is 14 times as potent as the chicken pox vaccine. Putting this potency into a more aged body that may have less defenses doesnt make sense to me.. Ive heard of elderly people getting shingles after having the vaccine. It isnt fail safe and doesnt reduce the risk of lingering pain if shingles does erupt. Since all vaccines are suspect until theyve been monitored for decades for long term dangers, this new vaccine is only 50% effective.. It is not suggested for people with medical conditions suppressing their immune systems such as organ transplant patients. The vaccine is also the most expensive at 200.00.

The virus lies dormant, lurking inside your body, and can become reactivated at any time. It sure sounds like something out of a science fiction movie, but the varicella zoster virus, which causes chickenpox and shingles, does just that. According to the Centers for Disease Control and Prevention, shingles affects about 1 million people in the United States each year. Once a person is infected with the varicella zoster virus, it remains in the nerve cell bodies even after the initial infection is past.. Unsightly shingles symptoms include a tender skin rash, usually on one side of the body. The initial rash forms blisters, which scab over in about a week. Additional symptoms may include chills, headache and fever.. Any area of the body can be affected, but the most common areas of occurrence are on the side of the body from the mid-back to the lower spine, says physician Bruce Ruben, MD, medical director of Encompass HealthCare in Michigan. Although it can occur at all ages, the incidence of ...

The term shingles refers to a condition caused by the varicella zoster virus, the same virus that causes chicken pox disease. After a person has had the chicken pox, the virus remains dormant, residing in nerve cells. Later on, as a result of many different factors, the virus may reactivate and leave the nerve cell and this is what causes herpes zoster, or shingles.. Reactivation usually occurs as a result of immune function abnormalities. Age, the presence of disease such as rheumatoid arthritis, or the use of immunosuppressive drugs all are risk factors.. Symptoms of shingles consist of an early prodrome or time before the storm. A patient will experience flu-like symptoms, headache, and possibly a low grade fever and chills.. Shortly thereafter, the patient will notice an itching, burning, uncomfortable sensation. This discomfort usually takes place on the chest or back, but it may also occur on the abdomen, head, face, neck, or an arm or leg.. Swelling of the lymph nodes near the area of ...

When a person becomes the victim of chicken pox, he gets rid of this disease within 10-15 days. Marks of chicken pox left behind the disease disappear after 5-6 months.

We identified 13 studies involving 69,916 participants. The largest study included 38,546 participants. All studies were conducted in high-income countries and included only healthy Caucasian individuals ≥ 60 years of age without immunosuppressive comorbidities. Ten studies used live attenuated varicella zoster virus (VZV) vaccines. Three studies tested a new type of vaccine not yet available for clinical use. We judged five of the included studies to be at low risk of bias.. The incidence of herpes zoster, at up to three years of follow-up, was lower in participants who received the vaccine than in those who received a placebo: risk ratio (RR) 0.49; 95% confidence interval (CI) 0.43 to 0.56, risk difference (RD) 2%, number needed to treat to benefit (NNTB) 50; GRADE: moderate quality evidence. The vaccinated group had a higher incidence of mild to moderate intensity adverse events. These date came from one large study that included 38,546 people aged 60 years or older.. A study including 8122 ...

Good questions. The chickenpox virus was originally thought to be related to the much more dangerous smallpox virus, but in the early 1900s it was realized that it is not at all like smallpox. Chickenpox, or varicella, is a member of the herpesvirus family of virues. That means it is related to Epstein-Barr virus which causes mono, and herpesvirus which causes fever blisters and other things. As far as I can tell (Im looking at an introduction to the history of virology from 1978) the guys who first described the chickenpox virus were E. Paschen, 1919; EE Tyzzer, 1906; von Bokay 1909. In 1954 Weller discovered that chickenpox and shingles are caused by the same virus (sorry this isnt more useful). Chicken pox generally breakout in epidemic form. For instance, it is believed that 90% of susceptible people (people who havent had chicken pox before) will get it when they are exposed to the virus. It will often run through a school or daycare or house very rapidly. The good thing about chickenpox ...

January 12, 2018 /AccessWire/ - LAWRENCE, MA / ACCESSWIRE / January 12, 2018 / The goal of the Centers for Disease Control and Preventions immunization programs is to see a reduction in the appearance of a disease, but sometimes just the opposite occurs, states Frank Magliochetti, Parcae Capitals managing partner. With a B.S. in Pharmacy, Frank Magliochettis participation in Northeastern Universitys Masters of Toxicology Program provides the foundation for his expertise in pain management and disease control, which is why a 39% rise in Shingles over an 18-year period drew Mr. Magliochettis concern. Lingering dormant in the body following both infection and vaccination, the Varicella Zoster virus responsible for Chickenpox, can be reactivated, emerging as the Herpes Zoster Virus, or Shingles. To combat such re-emergent diseases, breakthrough pharmaceutical solutions are paramount.. Scientists and researchers have sought to discover why the Zoster virus is prone to make an appearance later ...

In northern China (Jilin, Liaoning, Beijing, Shanxi and Inner Mongolian provinces), all clinical samples from varicella patients since 2009 belonged to clade 2 [28, 31, 33]. However, three clade 1 or 3 VZV strains circulating before 2000 were identified in Beijing by Loparev [2]. We speculate that the three clade 1 or 3 strains, which were either imported or random cases, were not the predominate clades in light of the current studies. In western China, 120 VZV strains including four varicella and 116 zoster samples were described in Xinjiang. The results showed that four varicella strains belonged to clade 2 and 116 zoster strains were distributed into 3 clades: 75 in clade 2, 40 in clade 5, and one in clade 1 or 3. Geography might cause multiple clade strains to co-circulate because it borders Gansu province, where clade 2 strains predominate. Additionally, Southern Xinjiang borders Pakistan and India, where clade 5 strains have been circulating [34, 35]. Northern Xinjiang borders Russia, ...

Varicella-Zoster disease (VZV) is a herpesvirus that becomes latent in sensory neurons after primary infection (chickenpox) and subsequently may reactivate to cause zoster. repression that is associated with latency of herpes simplex virus the prototypic alpha herpesvirus. Latency has been defined as the reversible nonproductive infection of a cell Amyloid b-peptide (25-35) (human) by a replication-competent virus (1). Several viruses have Amyloid b-peptide (25-35) (human) developed strategies to establish latency in the infected host to prevent their elimination by the host immune response. Varicella-Zoster virus (VZV) is an alpha herpesvirus that becomes latent in dorsal root ganglia (DRG) after primary infection and subsequently may reactivate to cause zoster. It is essential to understand the molecular mechanisms governing VZV latency and reactivation as approximately 15% of the human population will develop zoster (2 3 and possibly experience postherpetic neuralgia a debilitating pain ...

Herpes zoster (shingles) is caused by reactivation of the varicella-zoster virus that has been dormant since primary infection (i.e., chickenpox). It is characterised by pain in the area of the affected nerve, and crops of clustered vesicles (small fluid-filled spots) in the same area. Pain may occur days before the rash appears, or no rash may appear at all, which makes diagnosis difficult. Incidence is higher with age, and severity of symptoms is also much greater with age..

Immediate Care centers, also known as urgent care facilities, provide an alternative to emergency room service that is useful in many cases. They help patients who need quick attention but arent suffering from a life-threatening injury or illness. For example, doctors commonly advise people who have developed a case of shingles to seek immediate care if they cannot get a quick appointment with their own primary care physician. Since shingles are so painful, people typically seek fast help even if they have not been instructed to.. Shingles can develop in individuals who have had chickenpox since the varicella-zoster virus never leaves the body. It only becomes dormant. The disorder causes a rash with inflammation and small blisters, and usually, significant pain. The rash develops on the skin along nerve lines since the condition actually is an infection of the nerves as well as of the skin.. A shingles vaccination is available, but it usually is only administered to people age 50 and older. ...

Whitemill Medical Centre is ...

The risk of varicella and herpes zoster in immunocompromised individuals necessitates the development of a safe and effective varicella-zoster virus (VZV) vaccine. live (< 0.005) vaccine, and that of perforin mRNA in the animals that received the inactivated vaccine i.d. (< 0.005). Importantly, raises in the manifestation of IFN- (= 0.025), granzyme B (= 0.004), and perforin (> 0.05) mRNAs were observed in the animals immunized i.d. with 1,995 PFU of inactivated vaccine relative to those immunized s.c. with the same dose. The proportion of animals expressing IFN- mRNA mirrored the proportion expressing IFN- protein (correlation coefficient of 0.88). VZV glycoprotein-specific and virus-neutralizing antibodies were produced with no significant intergroup variations. A booster i.d. administration of the 399-PFU dose of heat-inactivated vaccine enhanced the antibody reactions. These results demonstrate that i.d. administration of an inactivated VZV vaccine can be an efficient mode of immunization ...
