Campylobacter is one of the major causes of gastroenteritis in humans resulting in more than 10,000 hospitalization and treatment cost exceeding 1.7 million (Mead et al. 1999). It is a self limiting disease and does not require antimicrobial treatment. But in rare cases where there is systemic involvement and in immunocompromised individuals, macrolides and fluoroquinolones are the drug of choices. Understanding the population genetics is important in identifying the sources and vehicles of contaminations for better understanding of the epidemiology and safeguarding the public health.
Isolates of Campylobacter from two different production systems (conventional and antibiotic free) and different geographic locations are included.
