Figure 1

Phylogeny of invasive multidrug resistant S. Typhimurium strains isolated from HIV-infected adults (A+) and children (C+) and HIV-uninfected children (C−) in Blantyre, Malawi, from the period 2002 to 2008 including the epidemic strain D23580. The phylogram also includes the reference gastroenteritis strain SL1344 and the invasive, chloramphenicol-susceptible, pre-epidemic strain A130 as outgroups. A clade consisting isolates from 2006 and 2008 only is highlighted in red. The scale bar value 0.2 represents expected substitutions per site.
