Gram stain revealed the presence of curved Gram-negative rods (Fig. 1A). BA and CHOC under aerobic conditions and Brucella blood agar + 5% sheep blood (BBA), belo horizonte medium (BHM), Campylobacter selective agar and Campylobacter blood free selective agar under micro-aerophilic conditions (6% O2 and 7,2% CO2) at 35Co. Bacterial growth was observed on the BBA and BHM plates (small golden colonies) (Fig. 1B and C). MICs are demonstrated in Fig. 1d.
