Trigeminal neuritis usually is caused by an inflammatory reaction to herpes simplex virus, which often resides within the gasserian ganglion of the trigeminal nerve. Transaxonal movement of the virus between the ganglion and peripheral nerves within the oral cavity has been documented [1 , 2]. The virus can be isolated from the painful aphthous ulcers within the oral cavity and the typical cold...

Herpetic keratitis which is resulted from herpes simplex virus type I, is considered the most common cause of corneal blindness that needs being diagnosed and treated in order to prevent irreversible eye effects. The best method to diagnose it is molecular method which has high sensitivity and exclusivity. The current study was done on 25 eye samples collected from patients referred to the Feyz...

Cerebellar disorders due to herpes simplex virus (HSV) infection are rare and always associated with herpes simplex encephalitis. We report 2 cases of severe primary acute cerebellitis caused by HSV type 1 that were identified by nested polymerase chain reaction performed on cerebrospinal fluid samples.

Unlike amantadine (1-adamantanamine), tromantadine (N-1-adamantyl-N-[2-(dimethyl amino)ethoxy]acetamide hydrochloride) inhibits herpes simplex virus type 1 (KOS strain)-induced cytopathic effect and virus replication with limited toxicity to the cells. Vero and HEp-2 cells tolerated up to 2 mg of tromantadine per 2 X 10(6) cells for 24-, 48-, or 96-h incubation periods with little change in cel...

Computer techniques were used to locate related segments of amino acid sequences in the thymidine kinases of vaccinia virus and of herpes simplex virus type 1 and in porcine adenylate kinase. As determined by a procedure that evaluates triply aligned sequences, the probability that the similarities among the segments described here arose by chance was no greater than 0.001. Because the sequence...

herpes simplex virus 1 (hsv-1) unspliced 8.3 latency associated transcript (lat), which located in the long repeat sequences, has been shown to contain at least 16 open reading frames (orf: a-p). one of these orf, orf p, maps almost entirely antisense to hsv-1 neurovirulence gene, icp34.5. both orf p and icp34.5 are located in the long repeat and are antisense overlapping genes. therefore, in o...

A herpes simplex virus type 1 strain isolated from a recurrent lesion of the nose reacted with monoclonal antibodies recognizing a type 2-specific site on glycoprotein D but not with monoclonal antibodies recognizing other type 2-specific sites. DNA sequence analysis of the glycoprotein D gene of the isolate revealed a single nucleotide alteration which changed the codon for asparagine to one e...
