“…According to other studies, B. licheniformis may or may not be susceptible to b-lactam antibiotics (Blue et al, 1995;Weber et al, 1988) but it is usually susceptible to carbapenems, glycopeptides, aminoglycosides, quinolones, chloramphenicol, peptolides and fusidic acid. B. licheniformis has also been found to be resistant to penicillin, fosfomycin, macrolides and nitroimidazoles (Ameur et al, 2005;Santini et al, 1995). Our patient was initially treated with b-lactam antimicrobials but the treatment was changed to the use of quinolones and then teicoplanin due to persistence of the bacteraemia.…”

Species of the genus Bacillus are a common laboratory contaminant, therefore, isolation of these organisms from blood cultures does not always indicate infection. In fact, except for Bacillus anthracis and Bacillus cereus, most species of the genus Bacillus are not considered human pathogens, especially in immunocompetent individuals. Here, we report an unusual presentation of bacteraemia and mediastinitis due to co-infection with Bacillus subtilis and Bacillus licheniformis, which were identified by 16S RNA gene sequencing, in a patient with an oesophageal perforation. Case ReportA 71-year-old male visited the emergency department with chest pain that was first noticed after swallowing tablets 3 h before admission. The pain progressively worsened and was associated with dyspnoea. On examination, his heart rate was 95 beats min 21 , respiratory rate was 30 breaths min 21 , blood pressure was 130/70 mmHg, body temperature was 36 u C and arterial O 2 saturation was 94 %. His medical history included a mild drinking habit and past pulmonary tuberculosis. He was also taking medicine for chronic obstructive pulmonary disease (COPD). The results of laboratory tests performed on admission were haemoglobin 14.3 g dl 21 , white blood cell (WBC) count 9.76610 9 cells l 21 (73.7 % segmented neutrophils, 15.9 % lymphocytes, 3.1 % monocytes, 6.6 % eosinophils), Creactive protein (CRP) ,0.3 mg dl 21 and creatine kinase myocardial band (CK-MB) 2.2 mmol l 21 . A computed tomography (CT) scan of the chest showed a pleural effusion in the left lower lobe and an oesophageal perforation was suspected. We believe that the tablets were the cause of this. Sputum and blood were cultured and empirical antimicrobial therapy with ceftriaxone, clindamycin, and gentamicin was administered. The next day, the pain continued, the CRP had increased to 12.57 mg dl 21 and his body temperature was 38.4 u C. A chest tube was inserted and blood-tinged fluid was drained. Over time, the CRP increased steadily to 29.53 mg dl 21 . Three sets of blood cultures and culture of the pleural fluid from the chest tube were performed. On day 4, the patient underwent an exploratory thoracotomy. In the mediastinum, pus and inflammatory tissue were observed and the pus was cultured; however, no oesophageal perforation was found. At the end of the operation, a chest tube was inserted and pus-containing fluid was drained.Colonies identified as members of the genus Bacillus were isolated from blood and pleural fluid cultured on days 1 and 2 and subcultures were performed on blood agar. Subsequently, the antimicrobial regimen was changed to moxifloxacin and clindamycin. After hospitalization, the patient had a persistent fever above 38 u C and the CRP remained high at 26.07 mg dl 21 .The subcultures grew various colonies of Gram-positive bacilli and the cultures taken on day 1 grew transparent, spreading colonies (designated colony 1). All three sets of blood cultures taken on day 2 grew two kinds of colonies: transparent, spreading colonies (designated colony 2) and ...

“…infections, most involving B. cereus [7][8][9], this is the first to specifically identify B. licheniformis as the infectious agent. B. licheniformis is a gram-positive, facultative anaerobic, spore-forming bacillus that is ubiquitous in nature [10].…”

“…It was necessary to establish, however, that the sepsis was due to B. licheniformis, especially since Bacillus sp. bacteria have been regarded as simple contaminants or as non-pathogenic, apart from Bacillus anthracis [10]. From the 1980s on, however, there have been several cases of B. licheniformis septicemia in adult patients presenting with various risk factors [6,[10][11][12][13][14][15][16][17].…”

“…B. licheniformis produces a glutamate polymer, which is responsible for the characteristic mucous aspect of its colonies and for the formation of a biofilm around central catheters. These may be responsible for the lingering characteristic of the septicemia and the possible relapses despite adequate treatment [10].…”

“…Although B. licheniformis may or may not be susceptible to beta-lactam antibiotics [12,19], it is usually susceptible to carbapenems, glycopeptides, aminoglycosides, quinolones, chloramphenicol, peptolides and fusidic acid [10,12,17] but resistant to penicillin, fosfomycin, macrolides and nitroimidazoles. In this case, amoxicillin, cefotaxime and vancomycin were effective against B. licheniformis.…”

Nosocomial infections in neonatal intensive care units are a preoccupying issue. Bacillus sp. can be pathogenic in immuno-compromised hosts, including premature infants. Central catheters and mechanical ventilation are potential sources of infection. We report for the first time a case of Bacillus licheniformis bacteremia in a premature infant. Recovery necessitated treatment with vancomycin and cefotaxime in combination with removal of the central catheter.
