ABSTRACT

Brucellosis remains endemic in many countries including Saudi Arabia. The disinfection of objects and surfaces contaminated with Brucella spp is not difficult, but we encountered a situation in which the organism survived the decontamination and liquefaction procedure adopted for AFB culture. A sputum specimen from a patient was sent for TB culture and the BACTEC MGIT 960 system isolated an organism identified as Brucella spp. The blood cultures and the serological testing had confirmed this case to be brucellosis. Isolation of Brucella spp from sputum samples is rare; this case appears to be the first of its kind. As the clinical presentation of TB may mimic brucellosis and vice versa, we recommend that handling specimens from all cases of undiagnosed PUO should be done with care because of the possibility that it may contain either of these organisms.

ABSTRACT

In this report we present a case of a young lady with abdominal abscesses and septicemia caused by Mycobacterium chelonae complex. Identification of the organism and initiation of the appropriate antimicrobial therapy was delayed, resulting in significant morbidity and multiple hospital admissions. Gram staining of these organisms from blood culture can be easily overlooked or confused with either debris or diptheroids. We concluded that detection of Gram-positive rod colonies should prompt an acid-fast stain to distinguish diphtheroids from rapidly growing mycobacteria in immunosuppressed patients.
