As we trudged knee-deep through the course of this year, we witnessed dramatic adjustments in our life. In scientific measurement terms, we experienced a “shift-ton” of change. Many human and pet viral strains arise from genetic mutations, processes commonly referred to as “shift and drift.” Antigenic drift represents subtle changes that occur through transcription errors. […]

In some parts of the country, fall has arrived. Unfortunately, in South Texas, we never really make the transition to fall colors, pumpkin spice, or crisp sunrises. What we settle for instead, is cooling weather and decreasing hordes of blood thirsty mosquitoes. These aerial vampires not only cause intense irritation and itching from bites, they […]
Continue ReadingAnother Shrimp FAD?
In our last podcast, we introduced our listeners to the basics of farmed Pacific white shrimp. But, with any commercial livestock operation comes increased risk of disease. The first disease we discussed was infectious hypodermal and haematopoietic necrosis virus (IHHNV). First reported this year, IHHNV was not the first shrimp FAD to occur in the […]

When we discuss foreign animal diseases, we usually think of mammals, with the occasional bird outbreak. But, in the field of veterinary medicine, we treat all species. Texas has extremely varied geographic terrain, allowing many different species to call this home. Farmed Pacific white shrimp offers a sustainable source of fresh shrimp to many areas […]

Vacation season draws to a close. School will soon start back. Many people enjoyed a relaxing getaway, and perhaps stayed in a nice hotel. In the recent outbreak of pneumonia in Atlanta, Georgia, we are reminded that occasionally people come home from vacation with more than a tan and some great memories. This particular type […]

Imagine a beautiful summer evening. You are sitting in your chair, listening to the birds and watching deer move in. Such a peaceful, serene, relaxing evening. Now, imagine the same idyllic scene with no deer. North American cervids are at risk of epizootic hemorrhagic disease virus (EHDV). As an Orbivirus, family Reoviridae, it comes as […]
Continue ReadingThreat From the South:VSV
The US is currently battling another foreign animal disease outbreak. Last week, vesicular stomatitis virus (VSV) was identified in two horses in south Texas and one in New Mexico. Summer breezes bring vectors up from Mexico. With low mortality, our greatest concern with VSV is its resemblance to important foreign animal diseases (FADs) like foot […]

We are going to step back from the normal informational post and test your foreign animal disease (FAD) knowledge. This post’s onus stems from my recent trip to Plum Island Animal Disease Center. I was struck by each disease’s clinical signs, and how easily I would have mis-diagnosed a FAD in practice.

The Chinese Nei Ching text dating back more than 4000 years (2700 BCE), attributes malaria to the machinations of three demons: one carrying a hammer, another a bucket of water, and one, a stove. While this helped explain the headaches, chills, and fevers then, today, vaccine researchers might be tempted to count a higher number […]
