Corynebacterium diphtheriae and Corynebacterium ulcerans are rarely isolated from clinical samples in Belgium. A case of toxigenic C. ulcerans in a woman is described, which confirms that this pathogen is still present. During investigation of the patient's cats, only a non-toxigenic toxin-bearing C. diphtheriae strain was detected.

A monoclonal antibody to the lipopolysaccharide of Moraxella bovis is described. In an indirect fluorescent-antibody test, this monoclonal antibody reacted with 39 of 39 strains of M. bovis tested and did not react with 26 nonfermenting gram-negative coccobacilli other than M. bovis. When used in an indirect fluorescent-antibody test, it proved useful for rapid and easy identification of M. bovis.

The authors report a fatal case of Corynebacterium sp. endocarditis. Corynebacterium spp. are non-sporulating, pleomorphic Gram-positive bacilli. In particular the authors have identified a species of Corynebacterium very closely related to C striatum. This is C simulans. The authors were able to identify the genus and species using various phenotypic tests. Highlighted here is the importance o...

A 28 year old man with no underlying disease developed a cavity and multiple nodules in the lung from which Corynebacterium equi was isolated. He experimented with organic solvents and microorganisms including Corynebacterium species for several years. Computed tomography of his pulmonary lesions revealed that these nodules were related to the bronchial tree. Histologically, the lesions were co...

Corynebacterium species other than Corynebacterium diphtheriae rarely cause infections in human but rather reside in flora, however they have been reported to cause opportunistic infections in both immunocompromised and immunecompetent patients. Here we report for the first time a case of an elderly female patient presenting with a fatal urosepsis caused by a recently defined pathogen, Coryneba...

The gas chromatography-mass spectrometry technique was employed to characterize n-decane oxidation products of Corynebacterium strains 7E1C and 269 (SNAM Progetti collection) after 73 h of incubation at 35 C. Corynebacterium 7E1C accumulated consistent amounts of esters of long chain acids with long chain alcohols, mainly decyldecanoate as well as products with mono- and diterminal carboxylic f...

Corynebacterium phoceense strain MC1 (= CSUR P1905 = DSM 100570) is a novel Corynebacterium species isolated from the urine of a kidney transplant recipient as a part of a culturomics study. Corynebacterium phoceense is a Gram-positive, sporogenous, strictly aerobic, and nonmotile coccobacillus. Here we describe strain MC1 and provide its complete annotated genome sequence according to the taxo...

The adhesion of Corynebacterium renale, Corynebacterium pilosum, and Corynebacterium cystitidis to various epithelial cell layers of bovine urinary bladders was examined. Adhesion was most efficient to the urinary sediment epithelial cells and the superficial cells immediately before shedding, followed by the remaining superficial cells and intermediate cells in this order, and least efficient ...

A total of 102 strains received as Corynebacterium 'group JK' were characterized by SDS-PAGE of their whole-cell proteins. Numerical taxonomy based on the protein pattern absorbance profiles indicated that 91 of the strains formed a cluster. Seventy strains isolated in the UK were identified as group JK, indicating the increasing detection of this group as opportunistic pathogens. Fine differen...

Mycobacterium bovis, the causative agent of the bovine tuberculosis (bTB), mainly affects cattle, its natural reservoir, but also a wide range of domestic and wild mammals. Besides direct transmission via contaminated aerosols, indirect transmission of the M. bovis between wildlife and livestock might occur by inhalation or ingestion of environmental substrates contaminated through infected ani...
