Branhamella catarrhalis conjunctivitis.

Eleven cases of Branhamella catarrhalis conjunctivitis have been reported. In four recent studies that examine the microbial etiology of ophthalmia neonatorum, B catarrhalis was identified only twice in 1,299 cases. However, diagnosis by Gram stain in some and previous antibiotic therapy in others may have resulted in underdiagnosis of B catarrhalis and inaccurate diagnosis as gonococcal ophthalmia.
