(a–e) FCV viral shedding and strain patterns of individual cats within each of the five colonies

In each colony cats are broadly divided into three groups, consistent shedders (C) positive on ≥75% occasions; intermittent shedders (I) positive on <75% occasions; non-shedders (N) never positive for FCV. For all colonies coloured squares represent FCV isolated, viral strain identified and viral titre (expressed as log₁₀ TCID₅₀ per 0.1 ml sample); empty square (□) represents no FCV isolated; grey square () represents FCV isolated but no strain information available; grey square () represents mixed FCV infection with two distinct viral strains; ns indicates that cat was not sampled; ^* Indicates cat was not part of the colony at the time of sampling; na represents cat was FCV positive but viral titre was not available; ^aFeHV-1 isolated. For individual colonies: (3a) Colony A, black square () is strain A1 and orange square () is strain A2; (3b) Colony B, brown square () is strain B1, green square () is strain B2, and blue square () is strain B3; (3c) Colony C, purple square () is strain C1; (3d) Colony D, red square () is strain D1, and blue square () is strain D2, recombinant virus is cat 24; (3e) Colony E, pink square () is strain E1 and yellow square () is strain E2.
