“…However, they have some limitations in identifying co-infections and dynamics of polymicrobial populations. These communities consist of bacteria, fungi, and viruses all potentially contributing to infection and inflammation ( Lu et al, 2011 ; Charlson et al, 2012a , b ; Delhaes et al, 2012 ; Fodor et al, 2012 ; Filkins et al, 2012 ; Carmody et al, 2013 ; Cui et al, 2013 ; Harrison et al, 2013 ; Huang et al, 2013 ; Dawood et al, 2014 ; Fitzpatrick et al, 2014 ; Goffard et al, 2014 ; Lim et al, 2014 ; McCullers, 2014 ; Mounier et al, 2014 ; Purcell et al, 2014 ; Willger et al, 2014 ; Wurzel et al, 2014 ). In addition, the majority of fungal species are difficult to cultivate or uncultivable on usual culture media as well as new or unknown pathogens ( Bittar et al, 2008 ; Chabé et al, 2011 ; Paniz-Mondolfi et al, 2012 ).…”
