On histology of penile and preputial epithelium, lymphoid aggregates may be identifiable. The inflammatory response in the female tract is similar and also non-specific, beginning neutrophilic and becoming a mixed infiltrate by the sixth week of infection. Infiltrates often surround the uterine glands in the stratum spongiosum and mast cells decline in number. By the twelfth week, cellularity has returned to normal. | On histology of penile and preputial epithelium, lymphoid aggregates may be identifiable.
