ABSTRACT
Dermatophytic mycetoma of the scalp is a rarity, especially when not associated with tinea capitis. Here, we report a case of dermatophytic mycetoma of the scalp, that was not associated with tinea capitis, caused by an atypical Microsporum audouinii strain. To our knowledge, this is the second reported case, thirty-eight years after the first that was published in 1980.

Microbial culturomics, which investigates microbial diversity by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA identification, allowed to identify five new species within the Bacillus genus. Bacillus massiliglaciei strain Marseille-P2600T, Bacillus mediterraneensis strain Marseille-P2384T, Bacillus massilinigeriensis strain Marseille-P2366T, Bacillus tuaregi strain Marseille-P2489T and Bacillus phocaeensis strain SIT16T are each the type strain of the corresponding bacterial species. These strains, the genomes of which are described here, are facultative anaerobic Gram-positive bacilli. Here, we describe the main characteristics of each bacterium and present their complete genome sequence and annotation.
ABSTRACT
The biochemical-based Carba NP test has been evaluated to detect carbapenemase-producing Enterobacteriaceae (n = 193) directly from spiked blood cultures. It was able to rapidly detect KPC (n = 50), IMP (n = 27), VIM (n = 37), NDM (n = 33) and OXA-48-like producers (n = 46) with sensitivity and specificity of 97.9% and 100%, respectively. This cost-effective technique may be implemented in any microbiology laboratory and offers a reliable test for an early identification of carbapenemase-producing Enterobacteriaceae directly from blood culture that could be useful for the management of infected patients.
