Background: Herpes simplex virus (HSV) is a widely distributed human pathogen that is known for its ulcerative lesions at the infection site. HSV can cause persistent infection in the host that is often followed by a period of latency within the neurons. Considering the high rate of HIV infection in South Africa, it is important to assess the seroprevalence of HSV with a focus to determine the epidemiological association between HSV-DNA and HIV-1 in the population. Methods: A total of 44 sera samples were screened for HSV and HIV-1 using the highly sensitive enzyme-linked immunosorbent assay (ELISA). The ELISA positive samples were characterized using polymerase chain reaction (PCR) to confirm the positivity of both viruses and to further differentiate HSV into HSV-1 and -2. Thereafter, the samples were analysed for relatedness using phylogenetic analysis. Results: Of the 44 samples, 36 (81.8%) were positive for HIV-1, while 35 (79.5%) were positive for HSV when screened with ELISA kits. The PCR results, with the use of type specific primers, showed that 4/35 (11.4%) samples were specific for HSV-1 while 30/35 (85.7%) were specific for HSV-2. Statistical analysis performed using the chi-squared goodness-of-fit test showed that there is a significant relationship between HSV-2 and HIV-1 transmission. Conclusions:There is a significant relationship between HSV-2 and HIV-1 in the study population. Our study shows that some of the HSV-2 isolates are not related to the clinical isolate SD90e from South Africa, suggesting diversity in HSV-2 viral transmission.

Conclusions: The prevalence of HSV in the population is high with an increased HSV-2 infection in women. Our study shows that some of the HSV-2 isolates are not related to the clinical isolate SD90e from South Africa, suggesting diversity in HSV-2 viral transmission.

ABSTRACTVirus-encoded proteins that impair or shut down specific host cell functions during replication can be used as probes to identify potential proteins/pathways used in the replication of viruses from other families. We screened nine proteins from herpes simplex virus 1 (HSV-1) for the ability to enhance or restrict human immunodeficiency virus type 1 (HIV-1) replication. We show that several HSV-1 proteins (glycoprotein M [gM], US3, and UL24) potently restricted the replication of HIV-1. Unlike UL24 and US3, which reduced viral protein synthesis, we observed that gM restriction of HIV-1 occurred through interference with the processing and transport of gp160, resulting in a significantly reduced level of mature gp120/gp41 released from cells. Finally, we show that an HSV-1 gM mutant lacking the majority of the C-terminal domain (HA-gM[Δ345-473]) restricted neither gp160 processing nor the release of infectious virus. These studies identify proteins from heterologous viruses that can restrict viruses through novel pathways.IMPORTANCEHIV-1 infection of humans results in AIDS, characterized by the loss of CD4+T cells and increased susceptibility to opportunistic infections. Both HIV-1 and HSV-1 can infect astrocytes and microglia of the central nervous system (CNS). Thus, the identification of HSV-1 proteins that directly restrict HIV-1 or interfere with pathways required for HIV-1 replication could lead to novel antiretroviral strategies. The results of this study show that select viral proteins from HSV-1 can potently restrict HIV-1. Further, our results indicate that the gM protein of HSV-1 restricts HIV-1 through a novel pathway by interfering with the processing of gp160 and its incorporation into virus maturing from the cell.

Type-specific serologic assays for herpes simplex virus (HSV) types 1 and 2 based on glycoprotein G-1 (gG-1) (HSV-1) and gG-2 (HSV-2) discriminate between antibodies against HSV-1 and HSV-2. We previously developed a Western blot assay using gG-1 and gG-2 expressed in baculovirus, performed extensive validation studies, and determined that it was both sensitive and specific for type-specific detection of HSV antibody. Here we report that, among a cohort of Thai military recruits, the serostatus of some individuals changed from positive to negative over time (6.6% among those ever positive for HSV-1, and 14.9% among those ever positive for HSV-2). We tested a subset of these specimens in three other gG-based assays: an enzyme-linked immunosorbent assay, an immunoblot strip assay, and a Western blot assay. Positive-to-negative shifts occurred in every assay; the frequency of the shifts ranged from 6.1% to 21.2% of the specimen sets tested. There was only limited agreement among the assays concerning which individuals lost reactivity. This inaccuracy, exhibited by all of the assay protocols, was not predicted by validation studies employing specimens from cross-sectional studies and was most pronounced in HSV-2 testing. This argues for the inclusion of serial blood specimens in serologic assay validation procedures.

The Russian kits «HSV-1-Fluorogen-screen» and «HSV-2-Fluorogen-screen» have been developed for the determination of antibodies M and G to herpes simplex virus types 1 and 2 by the immunofluorescence reaction. The kits were used to examine the positive and negative standard «EKOlab» panels sera and showed 100% sensitivity and specificity of the developed tests. 125 samples of blood serum from people with clinical diagnoses such as herpetic, cytomegalovirus infections, pyelonephritis, conjunctivitis and central nervous system damage were tested in parallel with using the enzyme-linked immunosorbent assay systems from different manufacturers and the developed tests «HSV-1-Fluorogen-screen» and «HSV-2-Fluorogen-screen». A high degree of matching of results with comparison sets was observed in examined samples. The developed diagnostics can be successfully used in clinical practice both for screening and for verification of results of the diagnosis of herpesvirus infections caused by herpes simplex virus types 1 and 2.

Background Herpes infections are common infections among populations. Herein, a cross-sectional study was used to determine the seroprevalence of herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) IgG antibodies and their association with potential infection risk factors among Jordanians. Methods A total of 759 serum samples were collected (January to February 2020) and analyzed for HSV-1 and HSV-2 IgG antibodies by enzyme-linked immunosorbent assay. Estimates for population seropositivity were determined by weighting the age-specific seroprevalence by the size of the population in each age stratum. Results The population estimate for HSV-1 seroprevalence was 75.3%. After adjustment for possible confounders, regression analysis revealed higher seroprevalence with increase in age ( p < 0.005) and low household income ( p = 0.002). The population estimate for HSV-2 seroprevalence was 2.9%. No significant differences in HSV-2 seroprevalence were observed in association with age, gender, family size, educational level, and socioeconomic status, likely due to low seropositivity. Conclusions Jordanians have high HSV-1 and low HSV-2 seroprevalence. Periodical studies might be needed to evaluate changes in HSV-1 and HSV-2 seroprevalence over time. This study provides essential epidemiological data for Jordan and the Middle East and North Africa region.
