Question Baby continued to have conjunctivitis despite therapy!

A newborn with bacterial conjunctivitis is treated with IV cefotaxime. Isolates grown on chocolate agar containing lysed blood show that the gonococcus is sensitive to cefotaxime. 1 week later, the neonate continues to have purulent discharge from his eyes. What is the likely cause?

A. Herpes simplex virus
B. Staphylococcus aureus
C. Chlamydia trachomatis of types D-K
D. Chemical irritation from silver nitrate
E. Chlamydia trachomatis of types A-C

Default not the most sophisticated mnemonic, but it works...

Chlamydia trachomatis....my mnemonic...

a, b and C = Conjunctivitis

D - K for "urethritis" (so, I use the word D__K )

L = lymphogranuloma venereum

Correct Answer

Chlamydial serovars D-K cause genital infections. These infections can be passed to neonates who pass through infected birth canals. When the mother has chlamydia, uterine contractions during parturition not only provide the force to deliver the newborn into the world, they also may pry the tiny newborn's eyelids open and thus expose the conjunctiva to the chlamydia-infested mucosa of their mother's birth canal. Hello world! Ahhh! My eyes!

So in this situation, chlamydia serovars D-K can cause anacute conjunctivitis. This stands in contrast to trachoma, which is a chronic conjunctivitis (mainly occurring in Africa) caused by chlamydia serovars A-C.
