Ja, aber sie sind zu klein, dass man es hรถrt.

There are a few open questions, though.
E.g. how does it work? In nearly half of the experiments host range didn't increase, there seem to be several factors.
Also, how broad a host range can you get? They tested on 59 isolates, but are they representative of the full range of strains?

It would be nice to be able to create phage preparations in the lab that have a high chance to work against unknown bacterial strains.

So far, matching a strain to an infection is time-consuming and success is not assured.
So there could be a way to broad-spectrum phage preparations here.

Experimental phage evolution results in expanded host ranges against antibiotic resistant Klebsiella pneumoniae isolates - Nature Communications Ghatbale et al. adapted a co-evolutionary technique to develop Klebsiella pneumoniae phages to be highly active longitudinally against K. pneumoniae clinical isolates, including drug resistant isolate...

I like this new phage paper by Ghatbale et al.

It appears that host range and killing power of phages targeting antibiotic-resistant bacteria strains can increase in lab evolution.

The narrow host range of phages is a serious issue in using them clinically against resistant infections. ๐Ÿงช

Which is simply not true, especially not in election results.

Social Democrats in Denmark suffer sweeping election losses PM Mette Frederiksenโ€™s centre-left party loses control of Copenhagen for first time in more than 100 years

I can't fathom why right-wing extremists are such a potent journalist honeypot. Another odd example in here: modest right-wing gains get a prominent spot at the top, while the major upset in copenhagen is further down and we are never really told where most of the other votes went. ๐Ÿคทโ€โ™‚๏ธ

Codonobdella is a genus of leech found in the depths of Lake Baikal - there are three different species, and unlike most leeches which feed on vertebrate animals, Codonobdella is a parasite of amphipods
