A small-animal model of genital herpes simplex virus (HSV) infection has not been available for investigating the pathogenesis of disease in males. Male Hartley guinea pigs were inoculated on the medial thigh with 10(5)-10(6) plaque-forming units of HSV type 2. Animals developed vesicular lesions in the genital area, including the penis. Transient urinary retention, hindlimb paralysis, and acute urethral shedding of HSV also occurred. During acute infection, virus was detected in neural and genital tissue homogenates, including the peripheral nerve, lumbosacral dorsal root ganglia (DRG), spinal cord, brain, vas deferens, epididymis, testes, seminal vesicle, and prostate. Recurrent disease developed in all animals. Persistent virus was detected in DRG but rarely in the vas deferens, seminal vesicle, epididymis, and testes. This model produces disease similar to that seen in men and should prove useful for studying the pathogenesis and immunology of male genital HSV type 2 infections.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D010413	Penis	The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.

D012008	Recurrence	The return of a sign, symptom, or disease after a remission.	Recrudescence,Relapse,Recrudescences,Recurrences,Relapses
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D005727	Ganglia, Spinal	Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.

D005837	Genitalia, Male	The male reproductive organs. They are divided into the external organs (PENIS; SCROTUM; and URETHRA) and the internal organs (TESTIS; EPIDIDYMIS; VAS DEFERENS; SEMINAL VESICLES; EJACULATORY DUCTS; PROSTATE; and BULBOURETHRAL GLANDS).
