Answer to Case 724
Answer to theParasite Case of the Week 724:Giardia duodenalistrophozoites and cysts.Florida Fan eloquently described the characteristic motility pattern ofGiardiatrophozoites: " Beautiful autumn leaves falling in the wind in a sliding side to side motion. " He also notes that "Giardiatrophozoites and cysts can present a little challenge to parasitologists at times. Most of us are used to see the typical kite-shaped trophozoite with its nuclei, sucking disks and flowing flagella. When these trophozoites turn sideways, we may see only ạ leafy profile, and when they stand on their tails they will look like the kid nex...

The Nuns, The Sisters, and The Golf Course
Kind of a weird title, no? I promise this will become clear as you read this post.
As I write this we are in the middle of a pandemic. There isn’t a lot to do because there is a mildly enforced stay-at-home order in place in New Hampshire. It doesn’t say you can’t go to work or get exercise, but you have to try to keep your distance from others. The virus that is the subject of this pandemic is a nasty creature. But I’m not going to talk about that in this post. Maybe another day.

Answer to Case 573
Answer to theParasite Case of the Week 573:Giardia duodenalis(a.k.a.G. lamblia, G. intestinalis) cystsThis is the third time I ' ve seen this finding in an anal pap smear - each time it was an unexpected, incidental finding. Despite this being a stain not commonly used in the parasitology laboratory, all of the key morphologic features including the nuclei, central axonemes, and curved median bodies, can be seen.

Answer to Case 571
Answer:Giardia duodenalis(a.k.a.G. lamblia, G. intestinalis) trophozoites with " falling leaf " or " tumbling " motility. Note that this is quite different than the " spiraling " motility ofChilomastix mesnili and the " jerky " motility ofPentatrichomonas hominis - two other flagellates - both non-pathogns - that may be seen in human stool specimens.As pointed out by Florida Fan, the motility is further enhanced by dark field videography, which makes everything more interesting. Thanks again to Idzi for the very cool videos!Santiago gave us further information on howGiardiatrophozoites move in the intestine to at...

Answer to Case 555 - Parasites and the Number Five
Wow - we received so many excellent comments on how parasites and the number 5 go together!

Campylobacteriosis in New Zealand
The following background information on campylobacteriosis in New Zealand is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. [1-2] (primary references available on request)
The incidence of campylobacteriosis exceeds that of any other reportable disease in New Zealand. In fact, Campylobacteriosis accounted for 42.5% of all notified cases of infectious disease in 2010. Highest rates are reported during late spring and early summer (November to January). Rates on South Island are correlated with lower socio-economic level, proportion of persons ages 25 to 44 and density of fresh food outlets...

aka Tropical Travel Trouble 009
The diagnosis of HIV is no longer fatal and the term AIDS is becoming less frequent. In many countries, people with HIV are living longer than those with diabetes. This post will hopefully teach the basics of a complex disease and demystify some of the potential diseases you need to consider in those who are severely immunosuppressed. While trying to be comprehensive this post can not be exhaustive (as you can imagine any patient with a low ...

A medical student who has just returned from their elective in Nepal presents with 1 week of bloody diarrhoea. He has been in the lowlands and stayed with a family in the local village he was helping at. It started three days before he left and he decided to get home on the plane in the hope it would settle. He is now opening his bowels 10x a day with associated cramps, fevers and has started feeling dizzy.

Living with two active kittens
This morning, after re-reading the last bit of Dr. Biswas’ EBV-MM thesis, I began looking at another area of research, concerning myeloma, of course. But then I decided to take a break and write a KITTEN POST. The kittens are asleep right now, so I have some time to do that…
Let’s see. We let the kittens out of their quarantine room on Saturday, December 30, 2017. They had been in that room, full of games and a floor-to-ceiling cat tower, since the beginning of November, when we first brought them home. It took almost two months for them to get their clean bill of health: no more giardia (!), no more ear mites,...

Got diarrhea? The latest trend in fashionable nonsense is “ raw water ”
In pseudoscience, appeals to nature are everywhere. It’s not surprising, then, that there is profit to be made selling “raw” (i.e., untreated) water at very high prices for its nonexistent health benefits, those benefits all claimed to be due to the “naturalness” of the water. I can’t help but note that cholera, Giardia, amoebic dysentery, and a wide variety of waterborne illnesses prevented by modern water treatment techniques are all very, very “natural."

Dendritic cells, miR-29b, and multiple myeloma
Life is very complicated these days. This morning, after consulting with the vet, I discovered that our giardia-ridden kittens will have to undergo a second cycle of treatment, which will begin next week. This means that they will have to spend another month holed up in their luxurious quarantine, poor dears! I am spending almost all of my free time with them…playing with them, feeding them, holding them, cleaning up, sterilizing, and being SUPER CAREFUL whenever I handle anything at all in the quarantine room.
Mind you, it may sound like it, but I’m not complaining. Not at all!!! I mean, just look at that fa...
