A Super Ager, Fauja Singh, ran his 1st marathon at age 89, and 8 more after that through age 101. How does he die at age 114 years? Hit by a car. apnews.com/article/olde...

Beautiful representation of feather follicles from a chickadee. A happy accident from the histology lab. They are not supposed to be sectioned obliquely but it makes them look pretty interesting in an abstract sort of way. 🪶

Submit your case for the Wildlife Pathology Workshop at #WDA2025 📅 Deadline for slide submission: June 9 🔬 Focus: Gross & histopathology of wildlife cases 📍 Held during the WDA Annual Meeting #VeterinaryPathology #WildlifeHealth #OneHealth wda2025.com/event/wda-an...

With 1,000 dairy herds affected by avian influenza and the disease regularly changing, the absence of this program is going to hurt. www.reuters.com/business/hea...

California is no stranger to domoic acid, but this year it's much worse much earlier. Stranded pinnipeds often exhibit listlessness, head bobbing, disorientation and seizures. Mortality rates are estimated to be ~25% www.fisheries.noaa.gov/feature-stor... #VetMed #MarineMammal #VetPath

Well, shit. This is going to cost us a lot more than the money saved. For the price of 38 Abrams tanks, #FAO has gotten a hell of a lot done with support from the U.S. kbhbradio.com/funding-term... #VetMed #AnimalHealth #OneHealth

This seems a bit obvious, but it's a very cool illustration of the idea. I tried to figure out where it was first published, but all I found were many social media posts with the image. Guilty!

The future is a web of branching paths, and each choice opens up new possibilities as it closes others. This is as true for a civilization as it is for an individual. The more our collective intelligence can inform each choice, the better our chances of finding paths through to a beautiful future.

Not a new article, but it's worth posting again just in case you missed it. Bullfrogs are normally tadpoles for 2 or 3 years. Something disrupted this one's metamorphosis so it just kept on growing! I love the references for scale! #frogs #wildlife www.americanscientist.org/blog/from-th...

If only we had a vaccine for ignorance. But, wait! We do!! Or, at least we did. Unfortunately, critical thinking and education, it would seem, are passé. www.nbcnews.com/health/healt...

An exhibitionist egret on display. These courtship threads beat millinery any day. Populations of common #egrets (and other spp.) were once decimated so we could put their nuptial plumes in women’s hats. Goshen Swamp, Liberty Co, Georgia. #birds #wildlife #NaturePhotography #Photography

These are some crazy kidneys! You don't have to be a pathologist to think these lesions are beautiful! I have suspicions as to pathogenesis, but histo will tell. 9-yo dog. Clinicians susp granulomatous osteomyelitis of lumbar v but no gross lesions were evident. #pathsky #vetpath #RenalPath

It's that time of year again! The #egrets are getting frisky. My parents are lucky enough to have a rookery in their backyard. Common egret, Liberty Co, #Georgia #birds #nature #wildlife #NaturePhotography #Nikon #swamp

Here's a case you don’t see every day! A hepatic sarcoma in a rat caused by tapeworm larvae. Taenia taeniaformis infestation with chronic inflammation and spindle-cell proliferation paves the way for neoplastic transformation. Nature is weird sometimes! #skypath #vetpath #parasites

I should have mentioned that RFK is the other well known cat who had a tapeworm larvae in his brain. This cat will survive. Luckily, he's not likely to seek a career in politics. That was a pretty big hole in his brain! #VetPath #Histopathology #Parasites bsky.app/profile/ucpa...

Coolest biopsy of the week! A coenurus from the brain of a cat. This tapeworm larvae has multiple invaginated scolices. The cat was doing well when discharged 7 days post op. #VetPath #PathSky #Parasites #Histopathology

The great-tailed grackle. My most favorite of all the grackles. Look at that tail! Look at that beak! He is seems pretty proud of the whole package. Woodland, CA. I wonder how long before they try to change the name to Quiscalus americanus. #birds #wildlifephotography #naturephotography

Looking for opinions on this (alleged) ovarian mass from a garter snake. I presume the amphophilic material is redundant basement membrane. Could this be a granulosa cell tumor? We have seen those in snakes (incl garter snakes) but this one is odd. #pathsky #vetpath #veterinary #tumor #repro

What's your diagnosis? American crow with a lesion on the back of the shank. I've seen this bird every day for a week and a half. #VetPath #AvianDisease #Veterinary #DermPath

Normally we go to Lake Solano (Yolo Co, California) to see the migrator waterfowl, especially the buffleheads and goldeneye. This day the #RiverOtters were putting on more of a show. #mammals #WildlifePhotography #Nikon #wildlife

A new kind of box #fish? Nope! It's much more interesting. This fishy cell has been stained with an antibody specific for rabies. They don't call it neurotropic for nothing! Antigen fills the cytoplasm but spares the nucleus creating a stark contrast betw the two.🧪 #histopath #PathSky #VetPath

It's a couple of years old but this is a great review of #rabies #virus #pathogenesis and #immune evasion. A student's question on antibody response prompted me to dig a little deeper in the literature. Who doesn't appreciate a good review article? onlinelibrary.wiley.com/doi/full/10....

It's "What Is Your Diagnosis?" Wednesday! What are your differential diagnoses for a flock of 20,000 Bovans Brown laying hens that experienced a 2-week period of increasing mortality starting at 54 weeks of age? Full case: doi.org/10.2460/javm...

A beautiful cleared example of Fascioloides magna that was submitted to the vet school. The large liver fluke leads to condemnation of beef livers and can cause significant disease in sheep and goats. I see it in white-tailed #deer, who don't seem affected. #veterinary #parasitology #trematode

Here is an awesome case from our #histopathology conference this morning! Lung from a #macaque. What's your dx? The residents hate it when I say, "It's a classic". But it is! 😊 #VetPath #PathSky #lung #parasites

FFS! Do NOT start calling this "Zombie Deer Disease"!! It is chronic-wasting disease (CWD). It's bad enough without giving screwball false impressions to the public. #deer #CWD #Veterinary #prion #SciComm www.11alive.com/article/life...

Last night friends asked me about the genetic test for intervertebral disk #disease (IVDD) in #dogs. I'm proud to say this comes from my department. Fibroblast growth factor 4 (FGF4) retrogene insertion on chromosome 12 (CFA12) #Science #VetPath #neurology journals.sagepub.com/doi/10.1177/...

I had originally shared a link to this article with my infectious disease class last year. Viruses are cool in all kinds of ways. David Goodsell makes them works of art. 🧪 www.science.org/content/arti... #science #InfectiousDisease #Viruses #ScienceArt

One of my favorite #birds. Like many #neotropical migrants, numbers of prothonatary #warblers are declining due to #HabitatLoss. The #cypress swamp where I took this photo was clear cut last year. It's just a big muddy hole now. #nature #wildlife. #WildlifePhotography

I must have been born with some lesion in that part of my brain. Anyone who has heard me singing at karaoke night would agree. 🙃 bsky.app/profile/scif...

When I was a resident we received a #parrot w/ #Chlamydia. The owner told us the ref vet said the bird prob got it from sexual contact with a person! 😂 Sounds dangerous! I hope our students now learn the difference between C psittaci and C trachomatis! 😬 #InfectiousDisease #Veterinary #bacteria

Come to Davis for the West Coast #Veterinary #Pathology Conference, May 2-3! We've got great speakers lined up, and we will have some fantastic cases for you to learn from. I promise it will be worth the trip. davisthompsonfoundation.org/event/great-... #VetPath #ReproPath #Theriogenology

We identified spatiotemporal clusters of #Chlamydia buteonis infection in raptors in Northern California. Cases were concentrated in winter near Sacramento. Uncertain why the spatial clustering occurs. #hawks #epidemiology #InfectiousDisease #Veterinary avmajournals.avma.org/view/journal...

I see many cases of #Chlamydia buteonis in #hawks @ UC Davis. I NEVER diagnosed it in 10 years of cases from the southeastern US. I'm sure I wasn't just missing cases in the SE. The hepatosplenomegaly and dark liver are profound. Airsaculitis is variable. #VetPath #Veterinary #InfectiousDisease

Chaperones help correct misfolding of #proteins and facilitate degradation of irreparable proteins. However, their interaction with #prions has some interesting results that may initially seem counterintuitive. Nice paper on the subject. 🧪 #TSE #CWD www.sciencedirect.com/science/arti...

Check out the massive numbers of #microsporidia in these sections! How many times have you had to search for #Encephalitozoon cuniculi? This is E. pogonae in #kidney of a bearded dragon. The lizards know how to grow Encephalitozoon. #PathSky #VetPath #Veterinary #Parasitology #Histopathology

My wife asked me to post this. She is a Deputy Director at California Office of Emergency Services (CALOES). Please share if you are connected to any folks in the LA area. Includes links to resources for those impacted by CA fires. #LosAngeles #Fire #CALOES www.ca.gov/lafires/

A dark morph red-tailed hawk for any (other) birding pathologists out there. A small lesion is on the left aspect of the cere. Apparent case of avian pox. Often self-limiting, but it can severely damage the rhamphotheca of raptors. Cedarville, CA #vetpath #birds #wildlife #InfectiousDisease

I saw a tundra swan yesterday with extreme cervical kyphosis. I don't know what might have caused it, but the bird was flying well. But it had a strange profile.

I took this photo of a sidewinder ages ago when I was doing my PhD in Tucson.  It was a good time to put my telephoto lens to use.  They are the fastest #rattlesnake. Most bites in AZ are due to the more common western diamondbacks. #wildlife #wildifephotography #nature #snakes #herps

AL amyloid in nasal mucosa of a horse. There was some disagreement in rounds over the papillomatous proliferation of the mucosa. I assumed it was just induced by edema and the pressure of the amyloid. Others thought it was strange with no ready explanation. #vetpath #PathSky #veterinary

All the other #ducks had beak envy. The lamellae along the edge of this northern shoveler's large bill are adaptations that help it filter food items from the water. Yolo County, California, USA #birds #waterfowl #wildlife #nature #WildlifePhotography

What's your dx? Laryngeal mass in a dog. We don't see too many of these in veterinary medicine. I'm curious if the MD's think it's a slam dunk without IHC. #PathSky #VetPath #Veterinary #RespiratoryPathology #Pathology

Here is a cool #histopathology slide to take your mind off the worries of the world! Eurytrema procyonis (a fluke for those wondering) in the pancreatic duct of a #raccoon. This #trematode is pretty well host adapted and is usually an incidental finding. #VetPath #PathSky #Parasite

Every year during the wildfires in our area, I look at the ash on the hood of my car and wonder whose house that once was. Did it belong to a friend of mine? Are they hurt?

Everybody seems to have a weekday theme, so I'm calling this wormy Wednesday! This is a very nicely cleared Fascioloides magna from a cow. I think the branching structures are the intestinal tract. Even flukes can be beautiful! #parasite #parasitology #veterinary #trematode

This #Canada goose sticks a perfect landing. My photography tribute to our cousins up North. I am sorry our family is so dysfunctional! Woodland, California, May 2024 #birds #wildlife #Wildlife #waterfowl

I am excited to begin my #OneHealth class for the undergraduates today. I'm working hard to inspire some of these kids to tackle these problems when they graduate. It's the least I can do, since my generation (and previous gen's) left such a mess for them. #Veterinary #WildlifeHealth #teaching

#MarineMammal harassment is an ever increasing problem. I photographed this jack ass at Children's Pool Beach. The #SeaLion was too boring for him while she was asleep, so he started poking her with the selfie stick. Apparently he's never seen a bite wound from a sea lion! #wildlife #nature

More images of the so-called Bullwinkle #deer from our paper a few years ago. The disease is relatively infrequent; many of our cases started w/ images posted on social media. Mannheimia granulomatis infection. journals.sagepub.com/doi/10.1177/... #PathSky #vetpath #CitizenScience #veterinary
