Figure 2.

Distribution of feline foamy virus (FFV) and feline leukemia virus (FeLV) log10 proviral loads (pVLs) in blood and oral specimens from singly or dually infected cats. FFV (A) and FeLV (B) pVLs were measured by quantitative PCR of mono- and co-infected domestic cats from Brazil. Mono- and co-infected cat samples for each retrovirus and in peripheral blood mononuclear cell (PBMC) or buccal specimens are presented. Horizontal lines above each graph depict statistical comparisons between the pVL of specific animal groups or specimen types (Student’s t tests), with associated probability (p) values shown. Ellipses in (B) represent different groups of FeLV infection outcome (regressive or progressive).
