This is probably the first report of the association of P.?inflatipes with an ophthalmological infection. This fungus has been reported as the aetiological agent of an invasive infection accompanying severe aplastic anaemia in a child. Other cases of human infections of Phaeoacremonium species included subcutaneous abscess, arthritis, infected cysts and disseminated infections [20]. Sequences obtained in this study were of good quality. A few ambiguities were resolved by proofreading the electropherograms and repeating the sequencing. Variability between sequences was controlled by using the consensus TRIB1 sequence of both forward and reverse strands. There exists no clear-cut unanimous definition of bacterial genus or species by rRNA gene sequence comparisons, although 16S rRNA gene sequence-based classification has become the reference standard. Various texts report different values used to define a species, from a range of about 0.5�C1% difference (99�C99.5% similarity or 0 to see more (unpublished data from this laboratory). Our results show the usefulness of DNA sequence-based classification over conventional phenotypic characterization of microbial pathogens. Its use can also lead to the identification of novel pathogens, such as Ralstonia mannitolilytica and Phaeoacremonium inflatipes. However, in this study, speciation was not achieved for some samples. This could be because of the presence of more than one species in the sample (streptococci and Enterobacteriaceae) or the BTK inhibitor limited range of reference sequences in the GenBank database (Sphingomonas and Chryseobacterium). Ribosomal RNA gene sequence analysis and PCR have successfully identified both common and unusual microbial pathogens of the eye. In the case of isolates obtained by routine culture, the method has confirmed (Streptococcus sp., Enterobacteriaceae, Pseudomonas aeruginosa) or corrected (Ralstonia mannitolilytica) the identification made phenotypically. The greater advantage of this technique, however, lies in its capability to identify bacteria that may be difficult or impossible to culture (Haemophilus influenzae, Mycobacterium sp.). This information is invaluable in arriving at an accurate clinical diagnosis which could translate to improved clinical outcomes.
