The sheep industry in Brazil is an important economic activity, and with the increasing global demand for sheep meat there is a great interest in the monitoring of the herd health, and serum reference ranges are basic tools for veterinary clinical pathology assays. Mineral elements correspond to 2-5.5% of the body of vertebrates, holding different functions in their physiology. The objective of this study was to obtain reference intervals of the electrolytes magnesium, phosphorus, chloride and calcium for the Dorper and Saint Ines sheep breeds. Sera samples were collected from 487 clinically healthy sheep, 146 from Dorper and 341 from Santa Ines breed. Electrolytes were measured using commercial kits. Data were analyzed taking the race, sex and age variables in account, and reference ranges were established. The results revealed significant statistical differences in reference ranges obtained for the electrolytes calcium and magnesium concerning the variable race, and for the electrolyte phosphorus in the variable age and, when compared with reference values already published, proved the existence of significant differences.
BackgroundThe evolution of Next-Generation Sequencing (NGS) has considerably reduced the cost per sequenced-base, allowing a significant rise of sequencing projects, mainly in prokaryotes. However, the range of available NGS platforms requires different strategies and software to correctly assemble genomes. Different strategies are necessary to properly complete an assembly project, in addition to the installation or modification of various software. This requires users to have significant expertise in these software and command line scripting experience on Unix platforms, besides possessing the basic expertise on methodologies and techniques for genome assembly. These difficulties often delay the complete genome assembly projects.ResultsIn order to overcome this, we developed SIMBA (SImple Manager for Bacterial Assemblies), a freely available web tool that integrates several component tools for assembling and finishing bacterial genomes. SIMBA provides a friendly and intuitive user interface so bioinformaticians, even with low computational expertise, can work under a centralized administrative control system of assemblies managed by the assembly center head. SIMBA guides the users to execute assembly process through simple and interactive pages. SIMBA workflow was divided in three modules: (i) projects: allows a general vision of genome sequencing projects, in addition to data quality analysis and data format conversions; (ii) assemblies: allows de novo assemblies with the software Mira, Minia, Newbler and SPAdes, also assembly quality validations using QUAST software; and (iii) curation: presents methods to finishing assemblies through tools for scaffolding contigs and close gaps. We also presented a case study that validated the efficacy of SIMBA to manage bacterial assemblies projects sequenced using Ion Torrent PGM.ConclusionBesides to be a web tool for genome assembly, SIMBA is a complete genome assemblies project management system, which can be useful for managing of several projects in laboratories. SIMBA source code is available to download and install in local webservers at http://ufmg-simba.sourceforge.net.
The number of draft genomes deposited in Genbank from the National Center for Biotechnology Information (NCBI) is higher than the complete ones. Draft genomes are assemblies that contain fragments of misassembled regions (gaps). Such draft genomes present a hindrance to the complete understanding of the biology and evolution of the organism since they lack genomic information. To overcome this problem, strategies to improve the assembly process are developed continuously. Also, the greatest challenge to the assembly progress is the presence of repetitive DNA regions. This article highlights the use of optical mapping, to detect and correct assembly errors in Corynebacterium pseudotuberculosis. We also demonstrate that choosing a reference genome should be done with caution to avoid assembly errors and loss of genetic information.

Although the authors maintain that the test procedures and results in the manuscript are valid and that they were not bound by a written contract with the product manufacturer, the authors have requested that the manuscript be withdrawn from publication in response to a cease publication demand from the product manufacturer specifying errors in the test methodology and results and contending that the study had been conducted pursuant to an arrangement with a distributor to perform product validity testing and that permission to publish an article based on such testing had not been obtained.
We present here the genome sequence of the attenuated Corynebacterium pseudotuberculosis strain T1. The sequencing was performed with an Ion Torrent Personal Genome Machine platform. The genome is a circular chromosome of 2,337,201 bp, with a G+C content of 52.85% and a total of 2,125 coding sequences (CDSs), 12 rRNAs, 49 tRNAs, and 24 pseudogenes.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
