Table 1.
Prevalence of Polychromophilus melanipherus and haemoplasmas in southern and eastern bent-winged bats by blood smear and/or PCR. All bats are adults unless otherwise indicated. n = sample size. NT = not tested due to insufficient blood volume collected. Intensity of infection = mean number of organisms observed/bat following a 10 min scan of the slide under oil immersion.
