Isolation and characterisation of nocardia from clinical specimens.

Sixteen isolations of nocardia of which 12 were from pulmonary infections, one from wound infection, one from mycetoma and 2 from eye infections were studied from June, 1989 to May, 1990. The importance of Gram's stain findings of primary smear is being highlighted. The nocardia species were identified utilising the morphological characters including acid fastness and cultural and biochemical characters. Notable among the isolates were Nocardia brasiliensis, one each from mycetoma and pulmonary infection, which are rare in South India and Nocardia asteroides from a case of endophthalmitis probably of endogenous origin.
