RESUMEN
In this study, in vitro activity of tigecycline (TIG) and ertapenem (ERT) against clinical isolates of Brucella melitensis and the effect of different media on in vitro test results were investigated. The in vitro effects of TIG and ERT to 38 B. melitensis isolates were comparatively investigated in brucella agar and 5% sheep blood agar. MIC value of ERT was 0.032 µg/mL in 23 of 38 and 20 of 38 isolates on blood and brucella agar, respectively. Minimum inhibitory concentration values of TIG were substantially different ranging between 0.064-0.25 µg/mL on blood agar. However, MIC values of TIG were similar on brucella agar with 0.25 µg/mL in 15 of 38 isolates and 0.5 µg/mL in 10 of 38 isolates. In conclusion, although ERT and TIG were effective against B. melitensis isolates in vitro, further studies are needed in order to determine the use of these novel drugs in treatment of brucellosis.

Crimean Congo haemorrhagic fever (CCHF) has been an emerging tick-borne infection in some parts of Turkey since 2002, with a number of fatalities. Many of the initial non-specific symptoms of CCHF can mimic other common infections. Additionally, the seasonal pattern of the epidemic, and the waning attention of healthcare workers to the yearly index cases caused some delays in appropriate patient care and treatment. Between March 2004 and August 2008, 140 confirmed adult cases were evaluated retrospectively for initial diagnosis and treatment delays. This study clearly demonstrated that there are particular delays (4.8 days) in the referral system to initiate effective antiviral treatment in the tertiary-care centre which significantly affect fatality rates (P>0.05). A large number of patients (n=95, 68%) received an initial misdiagnosis of various infections other than CCHF. In conclusion, continuous medical education regarding CCHF in the epidemic area is essential in order to achieve a better survival rate from this deadly infection.
