The role of the latency-associated transcript (LAT) in control of recurrent herpes simplex virus type 2 (HSV-2) infection was investigated by examining whether LAT concentration in vitro during productive infection or in ganglia during latency correlated with the frequency of recurrent genital herpes. Clinical HSV-2 isolates from frequent or infrequent recurrent genital disease produced comparable amounts of glycoprotein D and infected cell polypeptide 0 RNA, but the isolate from frequent disease produced about seven times more LAT. The guinea pig model of genital herpes was used to determine whether the quantity of LAT produced during acute infection in vitro correlated with recurrence phenotype; the frequency of recurrent disease was similar for the 2 clinical isolates. Likewise, there was no correlation between the recurrence phenotype of individual animals and LAT concentration in their ganglia. Thus, while absence of LAT may impair HSV reactivation and recurrence, once a threshold concentration is exceeded, LAT has no further effect on recurrence frequency.
