Multiple Factor Analysis of the phages host range, infection property, source of isolation, and bacterial host characteristics. a MFA ordination of quantitative variables. b and c The contribution of each quantitative variable to dimensions 1 and 2 of the MFA. c MFA ordination of qualitative variables. e and f The contribution of each qualitative variable to dimensions 1 and 2 of the MFA. Quantitative variables include antibiotic resistance, plaque size, host range, EOP value, phages latency period, and burst size- quantitative data were scaled. Qualitative variables include plaque morphology, source and location of isolation, and Pulsed-field Gel Electrophoresis (PFGE) type of the host
