Adult mice were inoculated intracerebrally with herpes simplex virus type 2 (HSV-2), and perfused at days 5, 8, 81, 108, and 130 after infection. Trigeminal ganglia and roots were dissected out and embedded in paraffin. Four 35S-labelled DNA probes that contained immediate-early (ICP-0, ICP-4), delayed-early (thymidine kinase; TK), or late (morphological transforming region; MTR) genes were prepared. In situ hybridization methods or an immunoperoxidase antigen method using HSV-2 antibody were applied to serial sections. During acute infection, use of each of the 4 probes (ICP-0, ICP-4, TK, MTR) gave hybridization signals in a distribution similar to that of antigen. During latent infection, only the ICP-0 probe gave hybridization signals overlying neurons, while in adjacent sections, the other probes (ICP-4, TK, MTR) did not show signals. No antigen was detected during latency. Hybridization signals were also demonstrated in nuclei of neurons during latency using a non-radioactive ICP-0 probe labelled with a steroid hapten. These results suggest that the transcription of the HSV-2 genome is restricted during latency, with transcript localization to nuclei of neurons as has been described in latent HSV-1 infection. Evidence for latent ganglionic infection by in situ hybridization in this model is consistent with that obtained by ganglionic explanation and by reactivations induced by immunosuppression.

D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D006561	Herpes Simplex	A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)	Herpes Simplex Virus Infection
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012668	Trigeminal Ganglion	The semilunar-shaped ganglion containing the cells of origin of most of the sensory fibers of the trigeminal nerve. It is situated within the dural cleft on the cerebral surface of the petrous portion of the temporal bone and gives off the ophthalmic, maxillary, and part of the mandibular nerves.
