Our results suggest that the nosocomial occurrence of IRAB is strongly related to an ICU stay and duration of hospital stay, and that IRAB occurrence may be favored by the selection pressure of previously used antibiotics.

41 Brucella strains isolated from blood and cerebrospinal fluid cultures were identified to species level and biotypes detected. All of the isolates were Brucella melitensis: 2 strains of B. melitensis biotype-1 and 39 strains of B. melitensis biotype-3. In vitro activities of these strains were detected by the E test method. According to the 90% minimal inhibitory concentration (MIC90) values, the most active agent was doxycycline (MIC90 0.064 microg/ml), followed by ciprofloxacin (MIC90 0.25 microg/ml), trimethoprim-sulfamethoxazole and ceftriaxone (MIC90 0.38 microg/ml). Rifampin exhibited the highest MIC90 value (0.75 microg/ml).

Brucellosis should be considered in the diagnosis of scrotal diseases in endemic areas. A conservative approach is usually adequate for managing brucellar epididymoorchitis. However, infertility problems may develop in these patients. Well-designed further investigations are needed to explain the relationship between brucellar epididymoorchitis and infertility in man.
