Sequences matching input query are shown below. Original reference, patient identifier, isolate name, partial treatment histories and accession number are indicated. Complete treatment histories, when available, can be accessed by clicking the isolate name. Sequences may additionally be downloaded in the fasta format, or viewed as individual or composite alignments using the options above. If the user wishes to view individual alignments of isolates for which there are multiple clones, the user can choose to view either an alignment of consensus sequences derived from the clones or an alignment of each clone as well as a consensus sequence.
