Comparison of polycarbonate and cellulose acetate membrane filters for isolation of Campylobacter concisus from stool samples

Diagn Microbiol Infect Dis. 2013 Aug;76(4):549-50. doi: 10.1016/j.diagmicrobio.2013.05.002. Epub 2013 Jun 3.

Abstract

One thousand seven hundred ninety-one diarrheic stool samples were cultivated for Campylobacter spp. We found a high prevalence of Campylobacter concisus with use of a polycarbonate filter (n = 114) compared to a cellulose acetate filter (n = 79) (P < .0001). The polycarbonate filter is superior to the commonly used cellulose acetate filter for detection of C. concisus.

Keywords: Campylobacter concisus; Campylobacter jejuni; Cellulose acetate membrane filter; Diarrhea; Polycarbonate membrane filter.
