“…The study of Wenocur et al (19) reported as in this work that the isolate was susceptible to penicillin. Unlike many Gram-positive bacteria, Leuconostoc species commonly demonstrate high-level resistance to vancomycin, with preserved sensitivity to most other antibacterial agents (22). A recent study (15) reported a case of Leuconostoc acute endophthalmitis.…”

Purpose: Endodontic infections are polymicrobial. This study was undertaken to characterize and perform an antimicrobial susceptibility test on Leuconostoc sp. isolated from acute endodontic infections in Ouagadougou, Burkina Faso. Methods:A cross-sectional descriptive study was conducted at Ouagadougou, Burkina Faso, from June to October 2014. A questionnaire form was used to collect the clinical data. Biochemical standard techniques were used to isolate bacteria, and identification was made by API 20 Strep gallery. Antimicrobial susceptibility was carried out by the diffusion method on a solid medium. Results:The age group of 19-40 years (67.7%) was more significant among the 93 patients included in the study. Acute cellulitis was accounted for 66.7% while acute apical periodontitis was observed in 33.3% of cases. Two exudate samples were positive to Leuconostoc sp. showing 100% sensitivity to lincosamides (lincomycin and clindamycin). On the other hand, they were 100% resistant to trimethoprimsulfamethoxazole, 50% resistant to the macrolides (spiramycin and erythromycin), and the 3 rd generations of cephalosporins (cefotaxime, cefuroxime, cefixime, and ceftriaxone). Conclusion:Leuconostoc sp. was associated with acute endodontic infections and an opportunistic pathogenic bacterium. The primary objective of the treatment of endodontic infection is to eliminate biofilms by a chemomechanical treatment. Dentists must avoid the overuse of antibiotics to prevent the emergence of antibiotic-resistant bacterial strains.

“…Leuconostoc can cause endocarditis, urinary tract infections, meningitis, intraabdominal infections, bacteremia, and septicemia. Central venous catheters and total parenteral nutrition are risk factors for infections with Leuconostoc, while newer findings showed that previous antibiotic treatment with vancomycin is not a risk factor for Leuconostoc infections [ 3 , 7 , 10 ]. In most cases, Leuconostoc showed good sensitivity to carbapenems (imipenem, meropenem), gentamicin, tobramycin, chloramphenicol, and the more recent daptomycin [ 3 ].…”

We present a 64-year-old man who was treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemoimmunotherapy for mantle cell lymphoma and developed purulent meningitis, probably caused by Leuconostoc sp. The patient had severe hypogammaglobulinemia, which is a possible complication of rituximab therapy. To our knowledge and after reviewing the available medical literature, this is the first described case of purulent meningitis caused by Leuconostoc sp. in a patient with mantle cell lymphoma that appeared after treatment with the R-CHOP protocol. The diagnosis of purulent meningitis was based on clinical, laboratory and cytological cerebrospinal fluid findings, in addition to blood culture results in which we isolated Leuconostoc sp. The patient was treated with meropenem with full recovery.

“…Although, there is an important caveat clinicians must consider when using vancomycin antibiotic therapy. When dealing with IE caused by Leuconostoc, vancomycin is not a suitable option for treatment [1]. Leuconostoc is a genus of Gram positive, catalase and oxidase negative, cocci placed within the family of leuconostocaceae [1,2].…”

“…It was previously believed that this bacterial species was non-pathologic in nature until recently published reports revealed the infectious potential of the Leuconostocspecies in many patient populations [2]. Although there have been previously reported sensitivity panels for this organism, it has a high level of intrinsic vancomycin resistance and therefore merits a higher index of suspicion when discussing endocarditis [1]. The case presented here serves to remind clinicians of the devastating potential of untreated infective endocarditis and to raise awareness for the possibility of infection with the typically non-pathogenic Leuconostoc species.…”
