The purpose of this study was to determine whether acyclovir resistance in mice infected with herpes simplex virus could be overcome by using high doses of acyclovir or vidarabine alone or by using a combination of the two drugs. The results indicate that the mice infected intracerebrally were refractory to acyclovir alone but responded to vidarabine or a combination of vidarabine and acyclovir...

The effects of 2,2'-O-cyclocytidine (CC) and acyclovir (ACV) on latent herpes simplex virus (HSV) in trigeminal ganglia were studied in an in vitro model using reactivation of HSV type 1 (HSV-1) as a model. It was shown that both CC (10 micrograms/ml) and ACV (2.5 micrograms/ml) significantly inhibited the reactivation of the latent HSV-1 in infected ganglia. The effect of CC (25 micrograms/ml)...

Hinze, Harry C. (University of Wisconsin, Madison), and Duard L. Walker. Variation of herpes simplex virus in persistently infected tissue cultures. J. Bacteriol. 82:498-504. 1961.-Cultures of human conjunctiva, HeLa, and KB cells infected with herpes simplex virus (HF strain) were cultured for prolonged periods in medium containing low levels of antibody. After continuous culture of the infect...

Recent work has demonstrated that following the clearance of infection a stable population of memory T cells remains present in peripheral organs and contributes to the control of secondary infections. However, little is known about how tissue-resident memory T cells behave in situ and how they encounter newly infected target cells. Here we demonstrate that antigen-specific CD8(+) T cells that ...

The Ile du Grand Connétable nature reserve is a rocky island off the Northern Atlantic coast of South America that hosts a unique population of Magnificent Frigatebirds (Fregata magnificens, Pelecaniformes). A high chick mortality, associated with nodular proliferative lesions, involving featherless areas, such as legs, neck, eyelids, and beak, was recorded during a consecutive 2 yr and affecte...

Infection of cells in G1 phase with herpes simplex virus (HSV) prevents their progression into S phase (de Bruyn Kops, A., and Knipe, D. M., 1988, Cell 55, 857-868). We have examined G1-phase events in infected cells to determine whether this effect was the result of inhibition of G1 phase progression or of entry into S phase. We observed that HSV infection decreased pRb phosphorylation and ind...

The recent association between Zika virus (ZIKV) infection during pregnancy and fetal microcephaly has led to a renewed interest in the mechanisms by which vertically transmitted microorganisms reach the fetus and cause congenital disease. In this Opinion article, we provide an overview of the structure and cellular composition of the human placenta and of the mechanisms by which traditional 'T...

The serological distinction between herpesviruses of oral or genital origin has been unequivocally shown by Schneweis (26), Plummer (21), and others (3, 20). Biological studies on the characterization of the 2 viruses have, in general, supported the idea of 2 discrete clusters. The 2 types behave differently in tissue culture held under particu lar conditions (5, 14, 15, 23) and the behavior of...

Bilateral mesiotemporal hyperintensity on T2-weighted and fluid-attenuated inversion recovery MR images of a patient with a clinical syndrome of encephalitis is considered to be a classic finding for herpes simplex virus infection. We report a case of neurosyphilis with identical MR imaging abnormalities and a similar clinical presentation. Because syphilis is not routinely tested for, awarenes...

Foscarnet is used to treat herpes viruses, including drug-resistant cytomegalovirus (CMV) and herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2). There are some reports of intravenous foscarnet-induced penile and vulvar ulceration. The authors report a case of the development of severe penile ulcers after the initiation of intravenous foscarnet therapy.
