Speciation and susceptibility of Nocardia isolated from ocular infections.
Twenty Nocardia spp. isolated from ocular infections were identified by 16S rRNA gene sequencing and susceptibility was determined using the E-test (AB Biodisk, Sweden). Species distribution among the 20 isolates was as follows: Nocardia levis (n = 7), Nocardia farcinica (n = 3), Nocardia abscessus (n = 2), Nocardia brasiliensis (n = 2), Nocardia amamiensis (n = 2), Nocardia puris (n = 1), Nocardia beijingensis (n = 1), Nocardia otitidiscaviarum (n = 1) and Nocardia thailandica (n = 1). All isolates were sensitive to amikacin. Eighteen (90%) isolates were sensitive to tobramycin, 11 (55%) to ciprofloxacin and gatifloxacin, and seven (35%) to azithromycin and clarithromycin. Molecular methods are useful for the identification and for the detection of Nocardia species that have not so far been reported in human infections.
