Comparison of conventionally and BED-estimated incidence: effect of long term infections.

<p>PY, person-years; CI, 95% confidence interval; LT, long-term infections. Adjustments were done as recommended by Welte et al. 2009 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0014748#pone.0014748-Welte1" target="_blank">[reference 17]</a>.</p

Phylogenetic relationship of the complete HBV genomic sequences of 4 long term care facility (LTCF) A residents with newly diagnosed HBV infection and representative HBV genotype A (n = 29) and D (n = 6) strains.

<p>Representative HBV genotype A and D strains were retrieved from GenBank and CDC's sequence database. The 4 LTCF A residents are shown by the solid boxes.</p

Phylogenetic relationship of the HIV sequences of 6 LTCF A residents with HIV infection (4 newly diagnosed), 23 reference US subtype B sequences, and one reference subtype C sequence (the outgroup).

<p>The 6 LTCF A residents are shown by the solid boxes. The tree was derived from a nucleotide alignment of the 1497-bp <i>pro-pol</i> region. Trees were inferred from 3 different phylogenetic analysis methods (neighbor-joining, maximum likelihood, and Bayesian inference) which independently showed that 2 sequences (COB 2 and COB 3) consistently cluster together with high bootstrap/statistical support (99/100/1.0 respectively). These two sequences show a pairwise nucleotide identity of 99.3%.</p
