Coryneform bacteria belonging to the genus Brevibacterium have emerged as opportunistic pathogens. Of the nine known species of Brevibacterium isolated from human clinical samples, Brevibacterium casei is the most frequently reported species from clinical specimens. We report the first case of B. casei brain abscess in an immunocompetent patient successfully treated by surgery and antimicrobial therapy.

Enrichment and elective culture for methylotrophs from sediment of the River Thames in central London yielded a diversity of pure cultures representing several genera of Gram-negative and Gram-positive bacteria, which were mainly of organisms not generally regarded as typically methylotrophic. Substrates leading to successful isolations included methanol, monomethylamine, dimethylamine, trimethylamine, methanesulfonate and dimethylsulfone. Several isolates were studied in detail and shown by their biochemical and morphological properties and 16S rRNA gene sequencing to be Sphingomonas melonis strain ET35, Mycobacterium fluoranthenivorans strain DSQ3, Rhodococcus erythropolis strain DSQ4, Brevibacterium casei strain MSQ5, Klebsiella oxytoca strains MMA/F and MMA/1, Pseudomonas mendocina strain TSQ4, and Flavobacterium sp. strains MSA/1 and MMA/2. The results show that facultative methylotrophy is present across a wide range of Bacteria, suggesting that turnover of diverse C(1)-compounds is of much greater microbiological and environmental significance than is generally thought. The origins of the genes encoding the enzymes of methylotrophy in diverse heterotrophs need further study, and could further our understanding of the phylogeny and antiquity of methylotrophic systems.

Brevibacteria are part of the normal flora of the skin and adjacent structures, but have been increasingly encountered in humans as opportunistic pathogens and have been isolated from various clinical specimens, generally causing infections in immuno-compromised patients. We present a case of a port-a-cath-related bacteraemia caused by Brevibacterium casei in a woman with a prior history of bilateral breast cancer. The clinical outcome was favourable.

Endophthalmitis is a serious post-traumatic ocular complication that can lead to loss of vision. We report a case of acute post-traumatic endophthalmitis following a penetrating injury caused by an unusual organism, Brevibacterium casei . The patient was successfully treated with intravitreal antibiotics like ceftazidime and vancomycin, along with topical cefazolin and tobramycin. Brevibacterium casei can be added to the list of rare bacteria causing endophthalmitis and should be kept in mind by clinicians as a potential source of pathology.

The susceptibility patterns of 480 isolates representing six recently defined species of coryneform bacteria (Corynebacterium amycolatum [n = 101], Corynebacterium auris [n = 48], Corynebacterium glucuronolyticum [n = 86], Brevibacterium casei [n = 50], Dermabacter hominis [n = 49], and Turicella otitidis [n = 146]) to 17 antimicrobial agents were determined by an agar dilution method. Most significantly, for C. amycolatum strains the MICs at which 90% of isolates are inhibited were > or = 32 micrograms/ml for nearly all agents. However, all 480 strains examined were susceptible to glycopeptide antibiotics.

We report a case of relapsing peritonitis in a 33-year-old woman on automated peritoneal dialysis. End-stage renal disease was secondary to systemic lupus erythematosus complicated with lupus nephritis. The organism isolated was Brevibacterium casei that was not readily identified, delaying appropriate management with an extended antibiotic course. Definite management of B casei peritonitis was peritoneal dialysis catheter removal.

Brevibacterium has been reported as a rare cause of implanted-device infection. In two cases of recurrent Brevibacterium casei bacteraemia associated with infection of surgically implanted intravascular devices, relapse occurred 2 and 5 months, respectively, after completion of therapy with vancomycin via the infected catheter. A second intravenous antibiotic therapy course by the antibiotic-lock technique led to bacteriological cure in one patient. Molecular typing results demonstrated that the recurrent bacteraemia was caused by the same strain. Implanted-device removal may be necessary, in addition to appropriate antibiotics, for successful management of such infections.

Journal of Applied Microbiology Jan 2009To study the evolution of rind microbial communities in Fontina PDO cheese.
AIMS
To study the evolution of rind microbial communities in Fontina PDO cheese.
METHODS AND RESULTS
Four batches were examined for their surface microflora during ripening, carried out in two different maturing caves, at Ollomont and Pré-Saint-Didier, Aosta Valley region, Northwest of Italy. Culture-dependent methodologies were combined with culture-independent analysis (PCR-DGGE). Yeasts were found to increase from 10(3) to 10(6) CFU cm(-2) in 28 days, with consequent rise of surface pH, which allowed the growth of salt-tolerant bacteria, in particular coryneforms which reached 10(9) CFU cm(-2) at the end of 3 months. Coagulase-negative cocci and lactic acid bacteria reached 10(7) CFU cm(-2) in the same period. Debaryomyces hansenii and Candida sake were the species more constantly present throughout the whole maturing process. As early as after 1 day since manufacture, Lactococcus lactis subsp. lactis and Streptococcus thermophilus were detected on cheese rinds. Arthrobacter nicotianae, Brevibacterium casei and Corynebacterium glutamicum were found after 7-28 days.
CONCLUSIONS
According to cluster analysis of DGGE profiles, the maturing environment seemed to influence the dynamics of microbial groups on Fontina surfaces.
SIGNIFICANCE AND IMPACT OF THE STUDY
These results represent a first picture of micro-organisms colonizing Fontina PDO rinds. Further studies are in progress to better understand the origin of this surface microflora and to formulate surface starters.
