Final answer:
Neonatal conjunctivitis can be caused by Chlamydia or Gonorrhea, which can be passed from mother to baby during childbirth.
Step-by-step explanation:
Neonatal conjunctivitis can be caused by two sexually transmitted infections: Chlamydia and Gonorrhea. Chlamydial conjunctivitis is caused by the bacterium Chlamydia trachomatis, while gonococcal conjunctivitis is caused by the bacterium Neisseria gonorrhoeae. Both infections can be passed from mother to baby during childbirth, leading to eye infections in newborns.
