Abstract: Peganum harmala L. (Zygophylaceae) has been used in a variety of practical applications in medical science. Our objective in the current study was to determine the effects of the seed extract on Herpes simplex virus type 1 (HSV-1) replication in Vero cells. Different concentrations (100, 500, 571, 667, 800 and 1000 µg/ml) of the extract were examined. Experiments were carried ...

OBJECTIVE Serological evaluation of herpes simplex virus infections during pregnancy. METHODS 2991 serum samples were obtained during 1st, 2nd, and 3rd trimester from 997 pregnant women. Baculovirus expressed glycoproteins gG1 (HSV-1) and gG2 (HSV-2) were used as antigens in ELISA for HSV-1 and HSV-2 IgG and IgA antibodies. RESULTS The prevalence of HSV-1 gG1 antibodies was 70% and that of ...

Herpes infections are among the most common sexually transmitted diseases and are the most common cause of genital ulcer disease in the United States. This study addresses the changing distribution of herpes simplex virus type 1 (HSV-1) and HSV-2 in patients presenting for evaluation of herpetic infections. Viral culture results from the University of Kentucky Clinical Microbiology Laboratory w...

BACKGROUND Neonatal herpes simplex virus (HSV) is a serious, life-threatening infection that is usually acquired during birth from contact with infected maternal genital secretions. Primary maternal HSV gingivostomatitis is a rare occurrence during pregnancy, and HSV type 1 (HSV-1) neonatal disease after primary maternal HSV gingivostomatitis during pregnancy has not been reported in detail. ...

OBJECTIVES Herpes simplex virus types 1 and 2 (HSV-1/2) may have adverse consequences on HIV type 1 infection. We quantified the frequency of HSV reactivations in highly active antiretroviral therapy (HAART)-treated adults with HIV, and compared it with that in HAART-naïve patients. SETTING 2 academic hospital sites in Toronto, Canada. PARTICIPANTS Asymptomatic HAART-naive (n=44) or treated...

BACKGROUND Herpes simplex virus (HSV) has two types: HSV-1 and HSV-2. Both infect epithelial cells and establish latent infections in neurons causing an infection that persists for life. Information on age- and gender-specific seroprevalence of HSV-1 and HSV-2 is valuable for understanding HSV transmission dynamics and designing population-based prevention and intervention programs for HSV. How...

Herpes Simplex Virus (HSV) is the most common cause of non-epidemic, acute focal central nervous system infection. HSV type 1 (HSV-1 or Human Herpes Virus-1 [HHV-1]) is commonly associated with oropharyngeal infections, keratoconjunctivitis, and infections of the central nervous system, whereas HSV type 2 (HSV-2 or HHV-2) commonly produces genital infections. Severe disseminated HSV infection m...

OBJECTIVE To establish risk factors for the presence of HSV-2 and HSV-1 infections in pregnant women. DESIGN, POPULATION, AND SETTING: A prospective study of 3306 women attending the antenatal department Westmead Hospital, Sydney, between June 1995 and April 1998. METHODS Women completed a self administered questionnaire to establish risk factors for the presence of HSV-2 and HSV-1. Sera were...

During lytic herpes simplex virus (HSV) infections, the HSV virion host shutoff protein (UL41) accelerates the turnover of host and viral mRNAs. Although the UL41 polypeptides from HSV type 1 (HSV-1) strain KOS and HSV-2 strain 333 are 87% identical, HSV-2 strains generally shut off the host more rapidly and completely than HSV-1 strains. In a previous study, we identified three regions of the ...

Thirty-seven bacterial clones producing human recombinant monoclonal antibody Fab fragments (rFabs) reactive to herpes simplex virus (HSV) antigens were selected from a human combinatorial antibody library constructed in a phage-display vector by a panning procedure against an HSV lysate. Thirty-four of the HSV-specific rFabs were able to specifically recognize HSV-infected cells in indirect im...
