Background: Infections caused by Prevotella bivia, a gram-negative anaerobic bacillus, are rare, with no reported cases in Japan. We present a novel case of scrotal abscess in a Japanese patient co-infected with Prevotella bivia and Streptococcus agalactiae. Case Presentation: A 41-year-old uncontrolled diabetic man complained of swelling and pain in the scrotum. On examination, computed tomography revealed an abscess of 5-cm diameter in the scrotum. Then, the abscess was incised and drained. He was treated with cefazolin empirically. Prevotella bivia and Streptococcus agalactiae were identified in the pus cultures obtained from the abscess. However, the susceptibility tests for Prevotella bivia could not be submitted. Seven days following admission, the pain reduced, and the drainage slowed. The patient was discharged on day 14 when cefazolin was discontinued and oral amoxicillin (750 mg/day) was started. Amoxicillin was continued until day 42; improvement was confirmed. Conclusion:To the best of our knowledge, this case is the first report of Prevotella bivia in Japan. We suggest that cephem antibiotics such as cefazolin may be effective against Prevotella bivia in Japan.

Prevotella bivia: A Rare Cause of Zuska’s Breast Disease

Zuska's breast disease is a rare disorder leading to recurring subareolar abscess typically in obese patients with a history of smoking. The pathophysiology is a combination of ductal obstruction from squamous metaplasia and infection usually by anaerobic and gram-positive bacteria. Zuska's breast disease does not have a single standardized treatment partly attributed to the lack of physician awareness of the disorder. The initial management should include smoking cessation, anaerobic and gram-positive antibiotic coverage, and drainage of abscesses if present.

“…Once thought to be relatively harmless with pathogenic potential only attributed to the toxigenic clostridia and Bacteroides fragilis, have emerged in major life-threatening infections including bacteremia, puerperal breast abscess and non-puerperal breast abscesses where they account from between 1-17% cases [9][10][11]. Boucher et al [10] reported P. bivia pure culture in a patient with non-puerperal breast abscess after flucloxacillin empiric therapy 500mg/6 hours for 2 days. AST results showed resistance to clindamycin but susceptible to amoxicillin-clavulanate, piperacillin-tazobactam, imipenem, and metronidazole.…”

The propensity to develop resistance to antibiotics has accounted for the predominance of Bacteroides and Prevotella in infections due to anaerobic bacteria. The observed differences in resistance pattern across geographical boundaries underscored the timeliness for this study to review data on antibiotic susceptibility and resistance markers amongst Bacteroides and Prevotella to β-lactams, lincosamide and nitroimidazole from selected hospitals in Lagos, Nigeria from 1992-2011. Bacteroides, mostly B. fragilis were the sole anaerobic gram negative bacilli in peritonitis following lower abdominal surgery and bloodstream infections, while Prevotella bivia and P. melaninogenica were more frequent in periodontal abscess, pelvic inflammatory disease and chronic suppurative otitis media. The MIC range and MIC90 of the anaerobes for the antibiotics does not indicate changes in group resistance to antibiotics though isolated cases were recorded. While clear cut patterns were not established for other species, B. fragilis resistance increased for amoxicillin-clavulanic acid from 18.2% in 1992-1996 to 31.4% in 2006-2011 and from 27.3% in 1992-1996 to 34.3% in 2006-2011 for cefoxitin. In contrast, decrease susceptibility was obtained against clindamycin (54.5% in 1992-1996 to 22.9% in 2006-2011). Similarly, 22.7% of B. fragilis strains have the cepA and/or cfxA gene in 1992-1996 compared to 32.1% in 2006-2011. While not all isolates with cepA and/or cfxA genes were resistant to the β-lactams, all isolates carrying the ermF or nim genes were resistant to the lincosamide (clindamycin) or nitroimidazole (metronidazole) respectively. The presence of antibiotics resistance genes can be used in tracking resistance amongst species of Bacteroides and Prevotella. With emerging new technologies, gene screening may prove more effective and reliable for therapeutic decisions for anaerobic bacterial infections especially since the genes can be screened from the infective exudates. This will eliminate the need for culture and antibiotic susceptibility testing for this group of fastidious microorganisms.

Nonpuerperal breast abscess due to Prevotella bivia

Abstract: Contrary to puerperal abscess, nonpuerperal breast abscess is often caused by anaerobic bacteria; polymicrobial aerobic‐anaerobic infections are also frequent. Empiric first‐choice treatment with broad‐spectrum antibiotics should be considered.
