Table 2. Prevalence of mosquito infection, determined by PCR performed using mosquitoes’ head-thoraces, by blood meal source (A) and mosquito species (B), and results of mixed effects logistic model on mosquito infection status (C).
| A | Prevalence of mosquito infection by blood meal source | |||

| End | 23.1 (25/108) | 25.0 (7/28) | 21.1 (4/19) | |
| B | Prevalence of mosquito infection by mosquito species* | |||
