Optimization of 16S rRNA gut microbiota profiling of extremely low birth weight infants

MP Biomedicals
27 Feb 2020

Infants born prematurely, particularly extremely low birth weight infants (ELBW), have altered gut microbial communities. There is a requirement to optimally characterize microbial profiles in this at-risk cohort, via standardization of methods, particularly for studying the influence of microbiota therapies (e.g. probiotic supplementation) on community profiles and health outcomes. Profiling of faecal samples using the 16S rRNA gene is a cost-efficient method for large-scale clinical studies to gain insights into the gut microbiota and additionally allows characterization of cohorts where sample quantities are compromised. To this end, the bacterial DNA extraction protocol from ELBW infant faeces was optimized by testing three different DNA extraction methods.

FastDNA SPIN Kit for Soil™

MP Biomedicals

Isolate Pure DNA from Cells Present in Soil or Other Environmental Samples! Thorough lysis in seconds of any microorganism present in environmental samples. Ready-to-use DNA for quantitative and qualitative characterization of microbial soil communities. Excellent reproducibility for an optimum assay-to-assay consistency. Total removal of humic acids and PCR inhibitors for a successful investigation of microbial diversity. The FastDNA™ SPIN Kit for Soil is designed to efficiently isolate bacterial, fungal, plant and animal genomic DNA from soil and environmental samples. Up to 500 mg soil are processed by the FastPrep®-24 5G or and any bead beating homogenizers with the Lysing Matrix E tubes designed to efficiently lyse all microorganisms including difficult sources such as eubacterial spores and endospores, gram positive bacteria and yeast. The released DNA is purified by a silica-based spin filter method and is suitable for PCR and other downstream applications.

DNA / RNA Extraction and PurificationPurified DNA and RNA are required for numerous downstream molecular biology applications. Consequently, the importance of high-quality DNA/RNA extraction and purification equipment cannot be underestimated. Many purification kits are available and are typically optimized for nucleic acid type and source, including plasmid DNA, genomic DNA, mRNA, RNA and viral nucleic acid purification kits. Automated extraction and purification of nucleic acids can be implemented with magnetic bead separator instruments or high-throughput purification workstations. Find the best DNA/RNA extraction and purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
