    • Abstract: Campylobacter spp. are Gram-negative, spiral, thermophilic, motile bacteria, which require microaerophilic environment for growth. They have restricted carbohydrate catabolism, but have well-developed mechanism of acquiring micronutrients instead. A common problem, especially in developing countries, is campylobacteriosis, mostly caused by Campylobacter jejuni. The major reason of this disease is the increasing

The drug resistance of these bacteria has been on the increase since the 1980s, leeding to their multi-drug resistance. Selective pressure, present mainly in the hospital environment, contributed to this phenomenon. However, also outside
