Introduction: Herpes Simplex Virus type 1 (HSV-1) is the virus that most often infects oral cavity. HSV-1 in latent phase migrates to trigeminal ganglion after primary infection and can reactivate cause recurrent intraoral herpes (RIH). The recurrence of RIH multifactorial triggered by decreased immunity, fatigue, hypersensitivity, stress, ultraviolet. Case: Three male patients came Oral Diseas...

Encephalitides, an acute infection of the brain parenchyma, are characterized by fever, headache and altered consciousness. Neurological deficits and focal or generalized epileptic seizures may also be seen. There are important differences in clinical presentations between encephalitides caused by viruses. While some viral encephalitides, such as Herpes simplex virus type-1 (HSV type-1) encepha...

A replication-defective mutant of herpes simplex virus 2 (HSV-2) was engineered by replacing the ICP8 gene of HSV-2 strain 186 with an ICP8-lacZ fusion gene from the herpes simplex virus 1 (HSV-1) HD-2 mutant strain. The resulting virus, HSV-2 5BlacZ, is defective for growth in Vero cells but is capable of growth in a cell line that expresses HSV-1 ICP8. In Vero cells, the mutant virus is defec...

Background: Herpes simplex virus (HSV) encephalitis is the most common cause of sporadic encephalitis, with significant morbidity and mortality that are effectively reduced by antiviral treatment. Herpes simplex infection in pregnant women rarely results in encephalitis. The most common symptoms of a pregnant woman with herpes simplex infection are colds and skin vesicles. Herpetic encephalitis...

We present a case of primary disseminated herpes simplex virus type 2 (HSV-2) cutaneous disease in a 22-year-old male. We discuss the immune response to HSV-2 infection as well as the extragenital manifestations of HSV-2 observed in immune-competent and immune-suppressed persons.

  Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

The susceptibilities of varicella-zoster virus (VZV) and herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) to 17 nucleoside analogs were compared by a plaque reduction assay with human embryonic lung fibroblast cells. The susceptibility of VZV to certain nucleoside analogs was different from that of HSV-1. Against VZV the 5-halogenovinyl-arabinosyluracils were the most potent of the compou...

Selective inhibition of herpes simplex virus (HSV) type 1 replication but not of HSV type 2 replication by (E)-5-(2-bromovinyl)2'-deoxyuridine (BVDU) was utilized to differentiate clinical isolates of these viruses. BVDU (0.7 microgram/ml) reduced HSV type 1 PFU by an average of 2.74 log10, but had no effect on the plaque-forming ability of HSV type 2 isolates. The incorporation of BVDU into th...
