Summary
Rhinovirus (RV) genotyping is now more consistent and scalable with rhinotypeR, an R package automating sequence analysis. This tool improves reproducibility for molecular surveillance of these common respiratory pathogens.
Area of Science:
- Virology
- Bioinformatics
- Computational Biology
Background:
- Rhinoviruses (RVs) are common respiratory pathogens, but their genetic typing is inconsistent across studies.
- Current methods for RV genotyping are fragmented, hindering reproducibility and scalability.
Purpose of the Study:
- To introduce rhinotypeR, an open-source R package for standardized and automated rhinovirus genotyping.
- To provide a reproducible and transparent workflow for molecular surveillance of RVs.
Main Methods:
- Developed rhinotypeR, an R package integrating alignment, distance calculation, genotype assignment, and visualization.
- Applied standardized, species-specific thresholds for genotype assignment (10.5% for HRV-A/C, 9.5% for HRV-B).
- Validated the package using a dataset covering over 90% of known RV types.
Main Results:
- rhinotypeR accurately reproduced genetic distances with high correlation (r=1.000, p=0.001) compared to existing tools.
- Achieved 80% agreement with previous genotype assignments, with discrepancies mainly near classification thresholds.
- Viral load (Ct values) did not appear to drive assignment discrepancies.
Conclusions:
- rhinotypeR offers a consolidated, automated framework for consistent rhinovirus genotyping.
- The package enhances reproducibility and scalability for molecular surveillance of RVs.
- rhinotypeR is available via Bioconductor for research and public health applications.

Cis-regulatory Sequences
11.9K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Sequences
295
Sequences are fundamental mathematical objects consisting of ordered lists of numbers that follow a specific rule or pattern. Sequences are critical in various mathematical concepts, including calculus, series, and number theory. They can model real-world phenomena such as population growth, financial investments, and physical processes like the diminishing height of a bouncing ball.Each number in a sequence is referred to as a term. Typically, the terms are denoted as a1, a2, a3,…, where...

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Arithmetic Sequences
243
An arithmetic sequence is a structured arrangement of numbers where each term is derived by adding a constant value, known as the common difference, to the previous term. This consistent pattern allows for the efficient computation of any term within the sequence as well as the cumulative sum of multiple terms. The formula for finding the nth term of an arithmetic sequence is:Here, aₙ represents the nth term of the sequence, a is the first term, d is the common difference, and n is the...

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H
6.8K
All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Geometric Sequences
289
In systems where values diminish by a constant proportion at each stage, the resulting sequence follows a geometric structure. Each new value in the sequence is obtained by applying a fixed multiplier to the preceding term. This regular, proportional decline type is often used to represent processes involving gradual loss, such as energy dissipation or reduction in amplitude over time.When analyzing the total effect of such a process across unlimited iterations, the series of values is referred...
