We are grateful to Dr. Delta for bringing to our attention these additional reports of listeriosis in infancy. These cases add further substance to the purpose of our paper: (1) Listeriosis in infancy is not as uncommon as might appear from sporadic, isolated case reports. (2) There may be a common denominator of the disease useful to the clinician and epidemiologist. (3) "Standard" antibiotic therapy for neontal sepsis may not be the treatment of choice.
