Join us for an intensive 4-day session on concepts in general pathology.
This medal has only been awarded 13 times since 1980 to eminent veterinary pathologists. It is highly fitting that Maja Suter is the first female recipient of the Olafson Medal.
Dr. John Cullen will provide an overview of the liver of domestic animals in health and disease with an emphasis on dogs and cats.
It was organized by Dr. Carlos Gonzalez from Andres Bello University, and sponsored by the Latin Comparative Pathology Group (the Latin-American Division of the Foundation).
Learn about glomerular pathology, glomerular ultrastructure, and pathology of tubulointerstitial disease.
The meeting was held at Texas A&M Galveston Campus in October, 2017. Annual dinner at Landry's!
It was held at the Universidad National de Colombia in Bogota, Colombia in August, 2017.
The Foundation held a 3-day course at the Veterinary School of the Universidad Mayor de San Marcos, in the San Borja District of Lima in August, 2017.
We are currently having problems with our bookstore, and we are sorry for the inconvenience. Please call the Main Office at 847-367-4359 to place all orders, and they will be shipped immediately. This problem should be resolved within the month.
The Foundation is proud to make Noah's Arkive, a searchable
collection of veterinary pathology images, available online at
no cost. Special thanks to the University of Georgia for transferring
the database and image collection to the Foundation!
The main goal of these Diagnostic Exercises is to provide interesting cases, focusing on the gross pathological lesions and associated histopathologic or cytologic findings. This material can be of great use for veterinary students, in-training pathologists, and ACVP diplomates alike.
There will be one contribution per month of the year; anyone may contribute. To do so, please contact Dr. Vinicius Carreira at vinicius.carreira@gmail.com to identify a convenient date for your submission and to receive templates to be used. Spots will be filled out on a first-come first-served basis.

New today in Noah - from new contributor Dr. Jenee Odani at the Hawaiian State Diagnostic Laboratory.
Tissue from a pig.
Morphologic diagnosis: Focal vesicular dermatitis of the snout.
Cause: Porcine picornavirus (Seneca Valley Virus)
Comment: Well, this has the potential to make for a bad day!
SVV results in vesicles on the snouts and coronary bands of pigs of all ages with occasional piglet mortality reported. It has been reported in reported in many countries including the United States, Canada, Australia, Italy, New Zealand and Brazil. Obvious and important ruleouts include Porcine rhabdovirus (VS), Porcine aphthovirus (FMD), Porcine calicivirus (VE), Porcine enterovirus (Swine vesicular disease).

Tissue from a duck.
Morphologic diagnosis: Hepatic amyloid
Comment: (From www.askjpc.org/wsco/wsc_showcase.php?id=175)
....Among birds, amyloidosis has been reported in most orders, but is particularly common in captive Anseriformes where incidences may be almost 80% in ducks and 50% in geese and swans examined at necropsy. In approximately 60-70% of amyloidosis cases in Anseriformes, an associated chronic inflammatory or infectious disease, such as mycobacteriosis, fungal disease, or enteric parasites, can be identified. It has also been associated with bumblefoot in Pekin ducks and can be induced experimentally in ducks and chickens with injections of a variety of bacterial and adjuvant components. The cases in which systemic amyloidosis is present without inflammation may be considered idiopathic or a result of nonspecific stresses associated with environmental conditions. For example, a study in white Pekin ducks free of chronic disease and parasites showed that increased crowding corresponded to increased rate and incidence of development of amyloidosis. Amyloidosis has been seen in approximately 20% of avian mycobacteriosis cases overall, and in up to 50-60% of the cases in Anseriformes.

Morphologic Diagnosis: Gastric foreign body obstruction, ceramic egg
Name the condition: Mistaken prey identity
Comment: Black rat snakes are egg-eaters, and will go to great heights to rob a birds nest. I have found them at heights of 50 feet (and I doubt they go there for the view). They frequently raid chicken houses and in this caes a duck rearing facility that used ceramic eggs to induce laying behavior or to study endocrine fluctuations. Snakes will ingest other round objects mistaken for eggs, such as light bulbs, rocks and golf balls. Differentials for a swollen stomach in a snake should include cryptosporidiosis and neoplasia (especially pyloric adenocarcinoma). Photos courtesy Dr. Lauren Powers.
New today in Noah from the AFIP Archive from I believe the collection of David Dodd and one that was taken when I was three years old. I don't know anything about this entity, and I hope someone can fill in the blanks for us....
Tissue from a sheep.
Name the condition: Wool cysts
New in Noah from Dr. Helen Acland of the University of Pennsylvania.
Tissue from a chicken.
Morphologic diagnosis: Hepatic lipidosis, fracture, and hemorrhage; fatty liver-hemorrhagic syndrome
Comment:This syndrome is most often seen in backyard chickens on an abundant, poorly balanced diet.
"Cheepers sure does love her french fries...."
