PCR analysis of DNA extracted from gastrointestinal tissues, using C. lanienae-specific primers. Representative results for one fecal DNA-positive animal using C. lanienae-specific primers (CLAN76F/CLAN521021R, 920 bp). C. lanienae-like DNA was detected in the cecum, colon, and feces. No DNA was detected in samples from the stomach, liver, or duodenum. S: stomach, L: liver, D: duodenum, Ce: cecum, Co: colon, F: feces. Data were replicated in three separate experiments.
