A two and half year old female child was admitted to the out patient department of V.M. Medical College, Solapur, with complaints of rhinitis, intermittent fever (100- 103F) and bilat­eral conjunctival mucopurulent profuse discharge of four days duration. Clinical examination revealed-conjunctival conges­tion and chemosis associated with mild oedema of both the eye lids, while, cornea, iris, anterior chamber and pupil by torch light examination did not reveal any apparent abnormality.

Gram and Giemsa stained smears from the inflammed conjunctivae showed abundance of polymorphonuclear leucocytes and a few gram positive bacilli. Conjuctival swab and scrap­ing were inoculated on common culture media. The colony smears showed gram positive bacilli while Albert's staining revealed 3-4 mm long slender bacilli studded with character­istic metachromatic granules. Subculture on Loffler's serum slope showed moist, confluent growth while potassium tellu­rite agar revealed greyish black, 1-2 mm sized circular low convex colonies. The morphological features of the colony smears were identical with that of the primary smear.

Glucose, sucrose and starch were fermented by the strain when tested in Hiss serum water, while phosphatase and urease tests were negative when compared with the positive and negative controls. The in vivo animal pathogenicity tests confirmed that the present isolate belonged to the gravis variant of Corynebacterium diphtheriae

Though Corynebacterium xerosis has been isolated from healthy and inflammed conjunctiva [1],[2] isolation of the patho­genic species of Corynebacterium diphtheriae has been rarely. reported [3],[4],[5] The present case manifested with catarrhal conjunctivitis and since there was no clinical evidence of diphtheritic pathology at the regular sites, the patient was discharged after local treatment. Subsequent follow up was not possible. The case is being reported for its unusual presentation and to our knowledge, such a case has not been described in Indian literature.
