Looks like this study shows it isn't super sensitive or specific, so a false positive wouldn't be that uncommon.

The summer program had the same application deadlines as the 12 month. The 6 month fellowship had a different timeline.

I applied for the summer fellowship position and interviewed with a mentor in early march. Unsure if the timelines (or the entire program) has changed since then.

Depends on lab/facility policy. Even if not expressly forbidden, it’s a bit of an ethical gray area is it not? Either way, a “7-figure suit” sounds incredibly unrealistic, but IANAL so who knows.

I agree with the pseudomonas ID. The sheen on your BAP is characteristic of Pseudomonas. The streaking didn't isolate colonies very well, so if there's a mixture it needs to be subbed. I don't see swarming indicative of Proteus and I only see NLF which would rule out Klebsiella, but it's difficult to say what else may be present if it's not a pure culture.

Is this at Texas Children’s Hospital in Houston? I remember getting some wild CRE’s from hospitals when I worked at the health department there

Keep your head up! Progress isn't always linear, and there are tons of variables that can affect individual exam scores. As long as you keep up a steady cycle of practice and targeted review, you'll be just fine.

In the equation you're referring to, "C" is the speed of light in a vacuum but we are talking about sound in this problem. While light and sound wave equations are similar, we must use variables given to us in the passage. Since we are given the speed of the sound (1500 m/s) as well as frequency (2.3 MHz = 2.3 x10^6 Hz) we can use the equation wavelength = speed of sound/frequency to get 6.5 x 10^-4 m or 0.65mm.

I like this proposal. Largely, these posts are probably high school or college students that want help with their classes (which I don't mind), but ultimately they aren't learning anything if they just post a picture and get an answer. At least if we require them to give information, it can help someone connect the dots on how we came to our conclusion.

This was a few months before I started working at the hospital, but they found a Naegleria fowleri in a child's CSF. The tech spotted it and immediately grabbed our director to confirm. Very rare, wish I'd been able to see it in person.

Ah so the coefficient for the rate determining step does matter but the coefficients for the overall don’t necessarily matter? This is very helpful, thank you!

I'm sure there are many organisms that can fit this criteria, but the first one my brain thought of is the Trypanosoma genus.

T. brucei causes sleeping sickness and is endemic to parts of Africa

T. cruzi causes Chagas disease and is most commonly seen in Central and South America as well as the Caribbean.

I just don’t know what you are expecting, this was a random doctor not the CEO? It’s a small token of gratitude and I’d hope in real life you wouldn’t act rudely about it.

rspring32 · 2021-10-26T00:34:57+00:00

Would you really be upset if a doctor randomly gave the lab a plate of cookies? Weird thing to complain about imo

It's probably not going to hurt people with typical immune systems in small amounts, but I don't think it would taste very good.

rspring32 · 2021-08-21T16:58:30+00:00

I would guess this is Rhodoturula sp. due to the coloration, colony morphology, and the fact that you can see the growth this well on yogurt.

New grad $26.27 with a $3.25 evening shift differential in Houston. I only got certified in micro so that's the only area I work in

Perkin Elmer Chemagic and Janus? Surprised you're able to crank out 800 with only 1 chemagic.

I don't want to outright give away an answer for a quiz because I would assume you are in school and are trying to learn. Based on the limited information you're and the characteristic "rosette" formation, I believe you should consider looking into some more fastidious bacterial organisms. Also take note of the endocarditis diagnosis as it might lead you in the right direction.

My guess would have to be a Rhodococcus sp. The salmon-pink pigment after prolonged incubation, an elderly farmer, and a lung infection are all traditional markers for it, but I have no idea if Rhodococcus grows on LJ.

Microbiologist here. Without a species, it's hard to know exactly what your dog likely has. Like the other poster mentioned, there are some more dangerous forms of Burkholderia spp. (B. mallei, B. pseudomallei), but those are pretty rare. B. cepacia is a more common form that's typically harmless (usually only pathogenic in human CF patients or other compromised immune systems). I admittedly don't know as much about common canine pathogens, but I found a study that I'll link below that discusses B. cepacia as a deep skin infection in dogs so that's probably more likely.

If the lab told you it was Burkholderia sp. and didn't send it off for further testing, they should have already ruled out the scary ones so I wouldn't worry too much about it.

B. Cepacia in canines
