Many times when susceptibility testing is done for P. aeroginosa, a scenario similar to shown in the picture is encountered.
We see that TZP has produced a D shape on the IPM side. This might look very similar to the phenomenon seen in gram positive ICR strains. So what is it?
Published data says that this result is most likely due to
inducible expression of the P. aeruginosa AmpC beta-lactamase.
Certain enteric
(Serratia, Providencia, Citrobacter, Enterobacter, Morganella) and non-enteric organisms (P. aeruginosa, Aeromonas) can up-regulate expression of
their chromosomally-encoded ampC genes in response to sub-inhbitory concentrations of certain
b-lactam antibiotics

1/ Happy Friday!
Today I am celebrating #scicomm! As of this week, I have contributed 21 articles to the @ASMicrobiology Bugs & Drugs blog! Here's a recap of some of these articles for those who love clinical #microbiology
#IDTwitter @ASCLS @CUAnschutz #MedEd @JClinMicro
2/ First, just a quick note on writing for @ASMicrobiology. Volunteering my time to write has been one of the highlights of the last 2 yrs for me! So grateful for the amazing Bugs & Drugs team, especially @JulieMarieWolf @JClinMicro @ScienceInTheDMV who took a chance on me.
#Publichealth piece discussing the yellow fever outbreak of 2015/16 in Africa & highlighting the amazing work of researchers working on fractional #vaccine dosing. It's an amazing story, full of impressive characters.…

1/I want to take some time to share findings from our semi-recent PETACS study. This was a wonderful collaboration between @COpedsID faculty, survey designers, and #microbiologists across the US.
@JClinMicro @ASMicrobiology #ASMClinMicro…
2/ First, I want to emphasize that this project highlights many of the reasons I chose to pursue a #PhD in clinical & translational science. As a long-time microbiologist, I can say that the clinical lab doesn't often have a seat at the clinical effectiveness / research table.
3/ This project focuses on the tracheal aspirate culture- a diagnostic process that is greatly limited by contamination with normal respiratory flora, and which lacks consensus or standardization across labs and hospitals. @ASCLS @ASMicrobiology @ASCP_Chicago

#MicroRounds (Day 733): Hypothetical case: a parent hears their child use the toilet but not flush (typical behavior!).

But upon entering the bathroom they're horrified to see this worm in the bowl with their kid's poop! How freaked out should they be?? #ASMClinMicro #IDTwitter A split picture: a tangled skinny worm (thinner than a stran
Cont.: Here's some additional information (from your friendly neighborhood parasitology lab).
1) Yes, it's actually a worm.
2) You zoom in close and see this on one of the ends of the worm... A split, three pronged brown worm.
#MicroRounds: If you see this worm in your toilet: relax. It didn't come from a person!

Ok, sort of weird to say...but today I'm dedicating some time to SPIT (formally known as #Saliva). It's the super hot topic this week in the ever-changing #COVID19 diagnostic landscape we are living in, so let's take a quick peek at some of the evidence out there (thread)
I completely understand the importance of testing saliva, particularly as it relates to lack of supplies and resources. It can be a feasible option that basically eliminates HCW risk of infxn during collection. It can also save supplies: no swabs, media, possibly fewer reagents.
First paper is here: DOI: 10.1128/JCM.01659-20
-53 paired samples from OP and/or NP swabs, and saliva were collected
-Standard RNA extraction methods were used for the swab samples, a quick extraction method was used for saliva. Handling high-viscosity samples is discussed.

Antibiotic testing. Let's go.

Tentatively calling this #tweetorial "Antibiotic testing: why and how and huh?"

Important caveat: this is a HUGE topic. I’m mostly going to focus on 1) basic rationale and 2) laboratory methods. And 3) try not to say anything wrong/misleading!
Question #1: Why would a person want to know if bacteria A is resistant to antibiotic B?
And the answer is ...

All are legit answers! But it's very situation dependent and you'd have different reasons for each. Let’s go through them.
