"Corynebacterium diphtheriae" is the classical etiological agent of diphtheria and the type strain of the genus "Corynebacterium." While diphtheria of the respiratory tract became rare with the introduction of vaccination programs in industrialized countries, even today several thousand cases per year are reported to the World Health Organization. This shows that diphtheria is not completely eradicated and that reservoirs exist. The book summarizes the latest advances made in understanding "C. diphtheriae" and the closely related species "Corynebacterium ulcerans" and" Corynebacterium pseudotuberculosis." Topics addressed are genomics of toxigenic corynebacteria, host-pathogen-interaction, detection, surveillance and treatment as well as application aspects.

Corynebacteria are a diverse group Gram-positive bacteria found in a range of different ecological niches such as soil, vegetables, sewage, skin, and cheese smear. Some, such as Corynebacterium diphtheriae, are important pathogens while others, such as Corynebacterium glutamicum, are of immense industrial importance. In fact, C. glutamicum is one of the biotechnologically most important bacterial species in use today with an annual production of more than two million tons of amino acids, mainly L-glutamate and L-lysine. Due to its industrial importance, C. glutamicum has been studied extensively over the years, and the publication of the C. glutamicum genome sequence in 2003 provided renewed impetus to these studies. To date, the complete genome sequences of four different species have been published, and sequencing of at least two more species is ongoing. These genomic data have enabled a dramatic improvement in our understanding of the corynebacterial genome architecture, metabolic p
