ABSTRACT
Corynebacterium ulcerans is an emergent pathogen infecting wild and domesticated animals worldwide that may serve as reservoirs for zoonotic infections. In this study, we present the draft genome of C. ulcerans strain 03-8664. The draft genome has 2,428,683 bp, 2,262 coding sequences, and 12 rRNA genes.
ABSTRACT
Corynebacterium ulceransis a pathogenic bacterium infecting wild and domesticated animals; some infection cases in humans have increased throughout the world. The current study describes the draft genome of strain 04-3911, isolated from humans. The draft genome has 2,492,680 bp, 2,143 coding sequences, 12 rRNA genes, and 50 tRNA genes.
ABSTRACT
Here, we present the draft genome of toxigenicCorynebacterium ulceransstrain 04-7514. The draft genome has 2,497,845 bp, 2,059 coding sequences, 12 rRNA genes, 46 tRNA genes, 150 pseudogenes, 1 clustered regularly interspaced short palindromic repeat (CRISPR) array, and a G+C content of 53.50%.
ABSTRACT
BACKGROUND: One difficulty of self-sustainability is the quality assurance of native products. This research was designed to study the risks and critical control points in the collection, handling and marketing of Brazil nuts from native forests and urban fairs in the Brazilian Amazon by characterisation of morphological aspects of fungi and posterior identification by molecular biology and determination of aflatoxins by high-performance liquid chromatography. RESULTS: Several corrective actions to improve product quality were found to be necessary in both sites. Growth of fungi was observed in 95% of fragments of Brazil nuts from both sites during the between-harvest period. Aflatoxin levels indicated that, although fungal growth was observed in both sites, only Brazil nuts from the native forest showed a high risk to human health (total aflatoxin level of 471.69 µg kg(-1)). CONCLUSION: This study has shown the main issues related to the process design of Brazil nuts, supporting the necessity for research on new strategies to improve the quality of nuts. Also, the habit of eating Brazil nuts stored throughout the year may represent a risk to farmers.

Here, we report the whole-genome sequences of two ovine-pathogenic Corynebacterium pseudotuberculosis isolates: strain 3/99-5, which represents the first C. pseudotuberculosis genome originating from the United Kingdom, and 42/02-A, the second from Australia. These genome sequences will contribute to the objective of determining the global pan-genome of this bacterium.

Corynebacterium pseudotuberculosis causes disease in several animal species, although distinct biovars exist that appear to be restricted to specific hosts. In order to facilitate a better understanding of the differences between biovars, we report here the complete genome sequence of the equine pathogen Corynebacterium pseudotuberculosis strain 1/06-A.
