Biotyping of thermophilic Campylobacter spp. isolated from poultry in and around Anand city, Gujarat, India

Abstract

Aim: To study the prevalence of different biotypes of thermophilic Campylobacter spp. in the study area. Materials and Methods: A total of 150 samples comprising 90 chicken and 60 caecal content were collected from retail meat market and processed for isolation of Campylobacter spp. 52 Campylobacter isolates obtained from raw poultry meat (6) and caecal content (46) were subjected to biotyping using Lior's biotyping scheme. Results: Among the 52 Campylobacter isolates studied, 60.46 % isolates were identified as Campylobacter jejuni Biotype I and 39.53% were C. jejuni Biotype II, whereas 83.33 % were C. coli Biotype I and 16.66 % C. coli Biotype II. No other biotypes were identified. Conclusions: The present study revealed that C. jejuni Biotype I was more prevalent than Biotype II whereas in case of C. coli, Biotype I was more prevalent than Biotype II providing basis for further epidemiological study.
