The comparison of the Butzler medium, filtration technique and their association with isolation of Campylobacter ssp

Abstract

Campylobacter was isolated in 178 out of 622 stool samples (200 porcine, 220 bovine, and 202 canine). From these 178 samples, the microorganism was identified in 64 samples (36%) isolated only in Butzler selective medium (BSM), 34 samples (19%) using filtration technique (FT), and in 80 samples (45%) using both BSM and FT. Comparison of the proportion of positivity using both techniques showed a significant value (c2 = 9,184; p > 0.001); BSM (36%) being more efficient than FT (19%). The use of both techniques yielded the highest isolation positivity (45%).
