Abstract
ARG-ANNOT (Antibiotic Resistance Gene-ANNOTation) is a new bioinformatic tool that was created to detect existing and putative new antibiotic resistance (AR) genes in bacterial genomes. ARG-ANNOT uses a local BLAST program in Bio-Edit software that allows the user to analyze sequences without a Web interface. All AR genetic determinants were collected from published works and online resources; nucleotide and protein sequences were retrieved from the NCBI GenBank database. After building a database that includes 1,689 antibiotic resistance genes, the software was tested in a blind manner using 100 random sequences selected from the database to verify that the sensitivity and specificity were at 100% even when partial sequences were queried. Notably, BLAST analysis results obtained using the rmtF gene sequence (a new aminoglycoside-modifying enzyme gene sequence that is not included in the database) as a query revealed that the tool was able to link this sequence to short sequences (17 to 40 bp) found in other genes of the rmt family with significant E values. Finally, the analysis of 178 Acinetobacter baumannii and 20 Staphylococcus aureus genomes allowed the detection of a significantly higher number of AR genes than the Resfinder gene analyzer and 11 point mutations in target genes known to be associated with AR. The average time for the analysis of a genome was 3.35 ± 0.13 min. We have created a concise database for BLAST using a Bio-Edit interface that can detect AR genetic determinants in bacterial genomes and can rapidly and easily discover putative new AR genetic determinants.

Gut microbiome recovery after antibiotic usage is mediated by specific bacterial species

TL;DR: Functional and growth analysis showed that microbiome recovery is supported by enrichment in carbohydrate degradation and energy production capabilities, and the ability of RABs to promote microbiome recovery with synergistic effects, providing a two orders of magnitude boost to microbial abundance in early time-points and faster maturation of microbial diversity.

Distribution of class 1 integrons in historic and contemporary collections of human pathogenic Escherichia coli.

TL;DR: The occurrence of class 1 integrons in human pathogenic E. coli is described in three isolate collections involving three periods from the last 100 years and the results compared with three established methods.

Whole Genome Sequencing of Extended-Spectrum- and AmpC- β-Lactamase-Positive Enterobacterales Isolated From Spinach Production in Gauteng Province, South Africa.

TL;DR: In this paper, the presence of multidrug-resistant (MDR) extended-spectrum β-lactamase- (ESBL) and/or AmpC β-Lactamases (AmpC) producing Enterobacterales in irrigation water and associated irrigated fresh produce was investigated.

Detection and characterisation of 16S rRNA methyltransferase-producing Pseudomonas aeruginosa from the UK and Republic of Ireland from 2003-2015.

TL;DR: In this article , 16S rRNA methyltransferase (16S RMTase) genes were identified using two multiplex PCRs, and whole-genome sequencing (WGS) was used to identify other antibiotic resistance genes, sequence types (STs) and the genetic environment.

An Acinetobacter non-baumannii Population Study: Antimicrobial Resistance Genes (ARGs).

TL;DR: In this paper, a comparative study of the resistomes of A. non-baumannii pathogens based on information available in published articles and genome sequences was performed. But the current information about antibiotic resistance genes in the different A.non-baumANNii species has not yet been studied as a whole.

Antibiotic resistance is ancient

TL;DR: Target metagenomic analyses of rigorously authenticated ancient DNA from 30,000-year-old Beringian permafrost sediments are reported and show conclusively that antibiotic resistance is a natural phenomenon that predates the modern selective pressure of clinical antibiotic use.
