Breast Abscess as a Complication of Human Brucellosis
ABSTRACT Breast abscess caused by human brucellosis is extremely rare. A 46-year-old woman received the diagnosis of brucellosis with positive serologic tests. Two weeks after the onset of symptoms, the case was complicated by vertebral (L5-S1) abscess which was treated by surgical drainage. One month after the diagnosis of brucellosis, the patient noticed a mass in her left breast. Breast palpation revealed a painless, mobile, round mass that was hypoechoic on ultrasound imaging. Purulent material was obtained by needle aspiration. Besides treatment of the breast abscess by needle aspiration, brucellosis was successfully controlled by prolonged antimicrobial treatment.

ABSTRACT: We report the microbiological, biochemical, and molecular characterization of an unusual Brucella strain (BO1) isolated from a breast implant wound in a 71-year-old woman with clinical symptoms consistent with brucellosis. Initial phenotypic analysis, including biochemical and antimicrobial susceptibility testing, cellular fatty acid analysis, and molecular analysis based on DNA-DNA reassociation and the presence of multiple copies of IS711 element suggested that the isolate was a Brucella-like organism, but species determination using microbiological algorithms was unsuccessful. Furthermore, molecular data based on 16S rRNA gene sequencing and multilocus sequence analysis demonstrated that BO1 was an unusual Brucella strain and not closely related to any currently described Brucella species. However, comparison with equivalent sequences in Ochrobactrum spp. confirms that the isolate is much more closely related to Brucella than to Ochrobactrum spp., and thus the isolate likely represents an atypical and novel strain within the genus Brucella.Journal of clinical microbiology 02/2008; 46(1):43-9.

ABSTRACT: Brucellosis is an endemic zoonosis seen in a variety of geographical locations such as the Middle East and Latin American and Mediterranean countries. Brucellosis is hyper-endemic in Saudi Arabia with an incidence of 5.4 per 1000 per year. Breast involvement very rarely occurs as a focal complication of brucellosis. We report six cases of breast brucellosis retrieved from the files of the patients. Fine needle aspiration (FNA) was performed on all patients. In all cases direct smears were made at the patient's side for assessment of sample quality. Cytospin and cell block preparation was done and Gram, periodic acid-Schiff and Ziel-Nelson stains were done on all samples. Microbiological analysis included routine fungal and bacterial culture for tuberculosis. Age range was 20 to 48 years with a median of 22 years. Two patients gave history of raw milk ingestion, one was lactating, and one patient was pregnant. Cytomorphologic features of brucellosis in the breast include an abscess-like background with granulomatous inflammation. Cytology of the patients presented with breast abscess showed predominant neutrophilic infiltrate compatible with acute pyogenic inflammation. Culture was positive for B. melitensis in all cases. Brucellosis should be kept in mind in the differential diagnosis of breast abscess in endemic areas where ingestion of unpasteurized milk and milk products is common. Needle aspiration establishes a preliminary diagnosis and has the advantage of material submission for microbiologic cultures and provides focal treatment along with long-term combined antibacterial treatment for the control of systemic infection.The Journal of Infection in Developing Countries 05/2009; 3(4):255-9.
