A 62-year-old man comes to the physician because of a growth on his penis that has been gradually increasing in size over the last year. He was diagnosed with HIV 10 years ago. He has been divorced for 25 years and has had “at least 30 sexual partners” since. Physical examination shows a nontender 2.5-cm ulcerated lesion with an erythematous base on the dorsum of the glans. There is firm left inguinal lymphadenopathy. A biopsy of the lesion shows small uniform basophilic cells with central necrosis that invade into the corpus cavernosum. This patient's condition is most likely associated with which of the following pathogens?
