Muy buen trabajo! Solo una aclaración: las más de 500 entradas del virus en España corresponden a toda la primera ola, no al mes de febrero. En este mes fueron muchas menos. Identificamos 6 ó 7, pero seguro que es una infraestructura.

CompBio method developers: software that only runs on your computer and is not available via a repository like CRAN, PyPI, Bioconductor, is not a proper research output —
just like a set of scribbled notes on your desktop is not the same as a preprint or a paper.
Finish the job.

Multidrug-resistant Gram-negative bacterial infections

Nenad Macesic, Anne-Catrin Uhlemann, Anton Peleg

Review in @thelancet.bsky.social

doi.org/10.1016/S014...
Figure 1 Mechanisms of action of key antibiotics for the treatment of multidrug-resistant Gram-negative bacterial infections

Several classes of antibiotics are available for the treatment of multidrug-resistant Gram-negative bacterial infections. Their mechanisms of action focus on key aspects of bacterial cell function, such as inhibiting cell wall synthesis (ie, β-lactams and fosfomycin) and function (ie, polymyxins), protein synthesis (ie, aminoglycosides and tetracyclines), folic acid synthesis (ie, trimethoprim and sulphonamides), and DNA replication (ie, fluoroquinolones). Because of increasing antimicrobial resistance, novel antibiotics have been developed to overcome some of these mechanisms; for example, by inhibiting antibiotic modification (ie, β-lactamase inhibitors) or by altering entry pathways (ie, cefiderocol, which enters via iron transporters). DHF=dihydrofolic acid. PABA=para-aminobenzoic acid. THF=tetrahydrofolate. Figure 2 Diagnostic testing of multidrug-resistant Gram-negative bacteria

Diagnosis of multidrug-resistant Gram-negative bacterial infections involves both species identification and antibiotic susceptibility testing. Although clinical microbiology laboratories have undergone automation of these processes and have seen the introduction of proteomic methods, such as MALDI-TOF, delays in turnaround time remain and might affect patient outcomes. New biochemical, molecular (eg, PCR), automated microscopy, and hybridisation-based rapid diagnostics now allow faster detection of antimicrobial resistance, including by testing clinical samples directly. Emerging technologies are seeking to improve both the speed of testing and provide more detailed information regarding the underlying mechanisms of antimicrobial resistance. MALDI-TOF=matrix-assisted laser desorption/ionisation time-of-flight. Figure 3 Summary of new antibiotic agents for the treatment of multidrug-resistant Gram-negative bacterial infections

Green=antibiotic is reliably active in vitro and guideline recommended. Yellow=variable activity; antibiotic might be effective if in vitro susceptibility is shown, clinical data might be lacking to support routine use. Red=not recommended, likely absence of in vitro susceptibility. IV=intravenously. *Administered simultaneously via Y-site administration. †Administration was studied in combination with imipenem–cilastatin. Figure 4 Summary of IDSA and ESCMID guidelines for the treatment of multidrug-resistant Gram-negative bacterial infections

3GCephR-E=third-generation cephalosporin-resistant Enterobacterales. AmpC-E=β-lactamase producing Enterobacterales. CRAB=carbapenem-resistant Acinetobacter baumannii. CRE=carbapenem-resistant Enterobacterales. DTR-P aeruginosa=difficult-to-treat resistant-Pseudomonas aeruginosa. ESBL-E=extended-spectrum β-lactamase-producing Enterobacterales. ESCMID=European Society for Clinical Microbiology and Infectious Diseases. IDSA=Infectious Diseases Society of America. MBL=metallo-β-lactamase. UTI=urinary tract infection.

Five years ago (Sunday 12 Jan 2020), five sequences of the new coronavirus were officially shared via GISAID, on a dedicated page revealed by a link on the GISAID homepage. ▫️1/

screenshot of the new webpage: 

[Title] Newly discovered betacoronavirus, Wuhan 2019-2020

A previously unknown betacoronavirus was detected in patients during an outbreak of respiratory illnesses, including atypical pneumonia, that started mid-December 2019 in the city of Wuhan, the capital of Central China's Hubei Province.
The newly discovered coronavirus is similar to some of the betacoronaviruses detected in bats, but it is distinct from SARS-CoV and MERS-CoV.
The genome of the newly discovered CoV consists of a single, positive-stranded RNA that is approximately 30k nucleotides long. The overall genome organization of the newly discovered CoV is similar to that of other coronaviruses. The newly sequenced virus genome encodes the open reading frames (ORFs) common to all betacoronaviruses, including ORF1 ab that encodes many enzymatic proteins, the spike-surface glycoprotein (S), the small envelope protein (E), the matrix protein (M), and the nucleocapsid protein (N), as well as several nonstructural proteins.

Our review is out in Nature Reviews Genetics! rdcu.be/d5AY2

We show how phylogeny-based methods can resolve the problem of non-independence in genomic datasets.

These methods must be considered an essential part of the comparative genomics toolkit.
