Long-Term Shedding of Influenza Virus, Parainfluenza Virus, Respiratory Syncytial Virus and Nosocomial Epidemiology in Patients with Hematological Disorders
Fig 3
Phylogenetic tree of parainfluenza virus sequences from the fusion gene was constructed with MEGA version 5.05 using the maximum likelihood method.
Patient numbers are indicated, reference sequences for parainfluenza virus type 3 selected from GenBank are indicated by their accession numbers. Bar indicates 0.1 nucleotide substitutions per site. Bootstrap values greater than 60 are displayed on branch nodes. Patient numbers of long-term virus shedding patients are indicated in bold.
