Herpes simplex viruses (HSV) are among the most widespread causative agents of human viral infections. HSV-2 is one of the commonest causes of genital disease, while HSV-1 is associated primarily with orolabial ulceration; however, recent changes in HSV epidemiology showed an increase in genital and neonatal herpes particularly caused by HSV-1. The main purpose of this study was to assess the seroprevalence of HSV-1 and HSV-2 in a random population in Siena (central Italy) in 2000, 2005 and 2013-2014 and in Bari (southern Italy) in 2005...

An estimated 417 million people worldwide ages 15 to 49 are infected with herpes simplex virus type 2 (HSV-2), the most common cause of genital ulcer disease. Some individuals experience frequent recurrences of genital lesions, while others only have subclinical infection, yet all risk transmitting infection to their intimate partners. A vaccine was developed that prevents shingles, which is a recurrent infection caused by varicella-zoster virus (VZV), a closely related member of the Herpesviridae family. The success of the VZV vaccine has stimulated renewed interest in a therapeutic vaccine for genital herpes...

PROBLEM: Herpes simplex virus 1 (HSV-1) commonly causes orolabial infection, but can also infect the genital mucosa. In contrast, HSV-2 is usually genital. Genital herpes can transmit the virus vertically to the fetus during pregnancy. We sought to estimate the prevalence of HSV-1/2 on the maternal and fetal sides of the placenta. METHOD OF STUDY: Placental tissues were collected from pregnant women seen at the Rio Grande University Hospital. HSV-1 and HSV-2 were detected by nested PCR...

INTRODUCTION: At the onset of the 20th century, ancient clinical observations of cancer epidemics in Bantu populations of Sub-Saharan Africa were discovered. They were reported from 1914 to 1960, but remained unexplained. In 1983, in San Francisco, Calif., USA, cancer epidemics were related to infections by the human immunodeficiency virus type 1 (HIV-1) known as AIDS disease. Yet since 1996, it is known that HIV-1 strains are not the only ones involved. In Sub-Saharan Africa, recurrent orobuccal herpes simplex virus type 1 (HSV-1) and genital recurrent herpes simplex virus type 2 (HSV-2) appeared many times prior to infection by HIV-1...

Genital ulcers are among the seven syndromes of sexually transmitted infections (STIs) identified in Côte d'Ivoire. Ulcerative STIs present a public health problem because of their frequency and their role in the spread of HIV. Our objective was to investigate the epidemiological characteristics of genital ulcers observed in the STI center of the National Institute of Public Hygiene in Abidjan. This cross-sectional, descriptive and analytical study examined cases seen at the center in 2008 through 2010. We retrospectively reviewed all files of clients aged 10 and older who sought care for the first time at the STI center and received a clinical diagnosis, confirmed by the laboratory, of a STI...

INTRODUCTION: Various forms of penile foreskin cutting are practised in Papua New Guinea. In the context of an ecological association observed between HIV infection and the dorsal longitudinal foreskin cut, we undertook an investigation of this relationship at the individual level. METHODS: We conducted a cross-sectional study among men attending voluntary confidential HIV counselling and testing clinics. Following informed consent, participants had a face-to-face interview and an examination to categorize foreskin status...

A defining characteristic of alphaherpesviruses is the establishment of lifelong latency in host sensory ganglia with occasional reactivation causing recurrent lytic infections. As an alternative to rodent models, we explored the use of an immortalized cell line derived from human dorsal root ganglia. HD10.6 cells proliferate by virtue of a transduced tetracycline-regulated v-myc oncogene. In the presence of doxycycline, HD10.6 cells mature to exhibit neuronal morphology and express sensory neuron-associated markers such as neurotrophin receptors TrkA, TrkB, TrkC, and RET and the sensory neurofilament peripherin...

OBJECTIVES: Genital herpes simplex virus-2 (HSV-2) shedding in pregnant women in association with neonatal herpes infection has been widely studied but there is limited evidence of its association with pregnancy outcomes. METHODS: In this retrospective observational study, we included a subgroup of pregnant women who were enrolled in a randomized control behavioural intervention study that was conducted in South Africa in 2008-2010. In pregnancy, women had a HIV rapid test done and a genital swab taken to test for curable STIs and HSV-2 DNA...

The high prevalence of herpes simplex virus 2 (HSV-2) infections in humans necessitates the development of a safe and effective vaccine that will need to induce vigorous T-cell responses to control the viral infection and transmission. We designed rAd-gD2rAd-gD2▵UL25rAd-▵UL25 to investigate whether recombinant replication-defective adenoviruses vaccine could induce specific T cell responses and protect mice against intravaginal HSV-2 challenge compared with FI-HSV-2. The recombinant adenovirus-based HSV-2 showed higher reductions in mortality and stronger antigen-specific T cell responses compared with FI-HSV-2 and the severity of genital lesions in the mice immunized with rAd-gD2▵UL25 was significantly decreased via eliciting IFN-γ-secreting T responses compared with rAd-gD2 and rAd-▵UL25 group in present study...

Herpetic whitlow is caused by herpes virus (type1 or 2) during primary infection or as result of autoinoculation. Commonly, it is caused by HSV-2 in adults with positive history for genital infection. We report a rare case of herpetic whitlow that should be kept in mind by physicians in recurrent cases of fingers infection. Advanced diagnostic techniques as PCR are required to help clinicians to achieve a definite diagnosis and to choose the right treatment.

Herpes simplex virus (HSV) causes significant morbidity on the human population through such clinical syndromes as cold sores, genital herpes, herpes stromal keratitis, and encephalitis. Attempts to generate efficacious vaccines to date have failed. We have recently described the use of a conditionally replication-competent HSV-1 vector to immunize mice against a lethal challenge of HSV-1. The unique feature of this vaccine vector is that its replication is tightly controlled and can only occur in the presence of local heat and the presence of a small molecule inducer (an antiprogestin)...

The patient is a 52-year-old African American man with a past medical history of HIV infection (on antiretroviral therapy, CD4 count 399 cells/µL, and undetectable HIV viral load) and recurrent genital herpes. While on valacyclovir, the patient presented with four tumorous lesions on the perineum and scrotum. A biopsy specimen stained positively with HSV-1 and HSV-2 immunostains and displayed a lymphoplasmacytic infiltrate. The patient received foscarnet and imiquimod for two weeks with minimal improvement...

REVIEW
Dinesh Jaishankar, Deepak Shukla
Etiology, transmission and protection: Herpes simplex virus-2 (HSV-2) is a leading cause of sexually transmitted infections with recurring manifestations throughout the lifetime of infected hosts. Currently no effective vaccines or prophylactics exist that provide complete protection or immunity from the virus, which is endemic throughout the world. Pathology/Symptomatology: Primary and recurrent infections result in lesions and inflammation around the genital area and the latter accounts for majority of genital herpes instances...

Background.: Genital herpes simplex virus type 2 (HSV-2) infection causes recurrent lesions and frequent viral shedding. GEN-003 is a candidate therapeutic vaccine containing HSV-2 gD2∆TMR and ICP4.2, and Matrix-M2 adjuvant. Methods.: Persons with genital herpes were randomized into 3 dose cohorts to receive 3 intramuscular doses 21 days apart of 10 µg, 30 µg, or 100 µg of GEN-003, antigens without adjuvant, or placebo. Participants obtained genital swab specimens twice daily for HSV-2 detection and monitored genital lesions for 28-day periods at baseline and at intervals after the last dose...

BACKGROUND: Herpes simplex virus (HSV) is a common human pathogen that causes a variety of diseases, including oral-labial, genital lesions and life-threatening encephalitis. The antiviral nucleoside analogues such as acyclovir are currently used in anti-HSV therapies; however, clinical overuse of these drugs has led to the emergence of drug-resistant viral strains. Hence, there is an urgent need to develop new anti-HSV agents. METHODS: To identify novel anti-HSV-1 compounds, we screened the LOPAC small scale library of 1280 bioactive compounds to identify inhibitors of HSV-1-induced necroptosis...

Homo sapiens harbor two distinct, medically significant species of simplexviruses, herpes simplex virus (HSV)-1 and HSV-2, with estimated divergence 6-8 million years ago (MYA). Unexpectedly, we found that circulating HSV-2 strains can contain HSV-1 DNA segments in three distinct genes. Using over 150 genital swabs from North and South America and Africa, we detected recombinants worldwide. Common, widely distributed gene UL39 genotypes are parsimoniously explained by an initial >457 basepair (bp) HSV-1 × HSV-2 crossover followed by back-recombination to HSV-2...

The herpes simplex virus (HSV) UL16 gene is conserved throughout the Herpesviridae and encodes a poorly understood tegument protein. The HSV-1 UL16 protein forms complexes with several viral proteins, including UL11, gE, VP22, and UL21. We previously demonstrated that HSV-2 UL21 was essential for virus propagation due to the failure of DNA-containing capsids (C capsids) to exit the nucleus. We hypothesized that if a UL16/UL21 complex was required for nuclear egress, HSV-2 lacking UL16 would have a phenotype similar to that of HSV-2 lacking UL21...
