Table 2 Comparison among polymerase chain reaction (PCR), immunohistochemical (IHC) and histopathological (HE) methods for Leishmania detection versus canine skin biopsies from different anatomical locations in 29 naturally infected dogs

From: Comparison of paraffin-embedded skin biopsies from different anatomical regions as sampling methods for detection of Leishmaniainfection in dogs using histological, immunohistochemical and PCR methods

Skin region PCR + (%) IHC + (%) HE + (%)
Ear 21a (72.4%) 14b (48.3%) 12b (41.4%)
Nose 19a (65.5%) 11b (37.9%) 5c (17.2%)
Abdomen 14a (48.3%) 11a (37.9%) 5a (17.2%)
  1. Each data point is associated a one letter (a, b or c). Data with the same letters means no statistical difference. Otherwise, different letters means statistical difference. Each line: Letters a, b, c, represent statistical analysis considering the three methods together. Different letter were used to significant differences, chi-square test (p < 0.05).
