Age distribution by species

Age distribution by species

Figure 2 shows the age distribution of bacteraemia reports for A. calcoaceticus/baumannii and A. lwoffii in 2008. While A. lwoffii was more frequently reported amongst children (less than 15 years) than A. calcoaceticus/baumannii, it was less frequently reported amongst those patients aged 15 years and over. The risk factors for A. calcoaceticus/baumannii infection include the use of invasive procedures (such as ventilator or cannula use) and broad-spectrum antibiotics and admission to Intensive Care Units (including neonatal ICUs)[1].

The distribution of A. calcoaceticus/baumannii shows peaks in the very young (less than one year) and the elderly (greater than 64 years), possibly as these age groups are more likely to require treatment in an ICU in comparison to other ages.
