Sporadic cases of infection with non-toxigenic Corynebacterium diphtheriae (C. diphtheriae) isolates have been reported in regions covered by the Diphtheria-Tetanus-Pertussis vaccine, but no information describing the whole genome of non-toxigenic strains collected in China is available.

Diphtheria remains a major public health concern with multiple recent outbreaks around the world. Moreover, invasive non-toxigenic strains have emerged globally causing severe infections. A diphtheria epidemic in the former Soviet Union in the 1990s resulted in ~5000 deaths. In this study, we analysed the genome sequences of a collection of 93 C. diphtheriae strains collected during and after this outbreak (1996 – 2014) in a former Soviet State, Belarus to understand the evolutionary dynamics and virulence capacities of these strains.

The study was performed for development of macro and micro morphological characters of Aspergillus isolated from groundnut seeds, groundnut cake and soil using cultural and microscopoic methods. Fungus colonies was inoculated in different media like Potato Dextrose Agar (PDA) and Yeast Extract Sucrose (YES) Agar and compared with standard cultures.
