Welcome to the National Animal Disease Center, a government research facility in Iowa where 43 scientists work with pigs, cows and other animals, pushing to solve the bird flu outbreak currently spreading through U.S. animals — and develop ways to stop it.
That’s where scientists work with more dangerous germs, including the H5N1 bird flu.
About 660 people work at the campus — roughly a third of them assigned to the animal disease center, which has a $38 million annual budget.
They were already busy with a wide range of projects but grew even busier this year after the H5N1 bird flu unexpectedly jumped into U.S. dairy cows.
Despite the spread in different animals, scientists were still surprised this year when infections were suddenly detected in cows — specifically, in the udders and milk of dairy cows.
It’s not unusual for bacteria to cause udder infections, but a flu virus?
Amy Baker, a researcher who has won awards for her research on flu in pigs, is now testing a vaccine for cows.
Baker and other researchers also have been working on studies in which they try to see how the virus spreads between cows.
AMES, Iowa (AP) — It appears to be a simple farm at first glance. Fields that are fenced in are .ted with cows. In the distance is a milking barn with a tractor parked next to it. However, the buildings there resemble modern universities rather than cow pastures, and the people who work there are not farmers.
Greetings from the National Animal Disease Center! This government research facility located in Iowa houses forty-three scientists who work with pigs, cows, and other animals in an effort to find a solution to the bird flu outbreak that is currently sweeping across the U.S. S. animals, and devise strategies to put a stop to it.
Tests on a cow vaccine intended to halt the virus’s further spread are especially crucial since they may lower the likelihood that it will eventually spread to people and cause a serious illness.
The US. s. Ames, a college town 45 minutes north of Des Moines, hosted the Department of Agriculture facility when it first opened its doors in 1961. Situated a few miles east of Ames’s low-lying downtown, the center spans 523 acres (212 hectares) on a pastoral landscape.
It is a serene location with a lengthy past. There, scientists have created vaccinations over the years to protect pigs and cattle from a number of diseases, such as brucellosis and hog cholera. Additionally, research conducted there during the 2009 H1N1 flu pandemic, also referred to as the “swine flu,” demonstrated that the virus was limited to pigs’ respiratory tracts and that pork was safe to eat.

There aren’t many locations in the U.S. with that capacity. s. have,” stated Webby, who has been working on the cow vaccine project with the Ames facility.
There are ninety-three buildings on the campus, one of which is a high-containment laboratory building. Its exterior is modeled after a contemporary megachurch, but inside are divided hallways and rooms, some of which house diseased animals. Scientists use more pathogenic bacteria there, such as the H5N1 bird flu. There is also a testing center, which is a “for animals” version of the CDC labs in Atlanta that identify uncommon (and occasionally frightening) new human infections, and a three-story office building housing researchers studying animal diseases.
The campus employs about 660 people, with the animal disease center accounting for about one-third of them and having an annual budget of $38 million. They were already extremely busy with a variety of projects, but this year they became even more so when the H5N1 bird flu unexpectedly spread throughout the U.S. s. milking cows.
The director of the center, Mark Ackermann, remarked, “It’s just amazing how people just dig down and make it work.”.
Since its discovery in 1959, the virus has spread widely and proven to be a highly deadly threat to domesticated poultry and migratory birds. As this was going on, the virus changed, and over the last few years, it has been found in an increasing number of animals, including polar bears, sea lions, dogs, and cats.
This year, infections in cows—more precisely, in the udders and milk of dairy cows—were unexpectedly discovered, shocking scientists despite the fact that the infections had spread to other animals. Although udder infections are frequently caused by bacteria, a flu virus?
As a general rule, we consider influenza to be a respiratory illness, according to researcher Kaitlyn Sarlo Davila of the Ames facility.
The Ames center was brought into the picture when the virus started showing up in cows, although the majority of the disease’s research has been done at a USDA poultry research center in Athens, Georgia.
Amy Baker, a virologist who has been recognized with awards for her studies on pig flu, is currently conducting trials on a cow vaccine. She stated that preliminary results should be available shortly.
Although the work is still in its early stages, USDA spokesperson Shilo Weir called it promising. There isn’t currently a licensed bird flu vaccination in use in the U.S. s. Weir stated that although vaccines for poultry are being researched, eradicating the virus would be difficult and uncertain with such a method.
Baker and other scientists have also been conducting studies to try and figure out how the virus spreads amongst cows. Scientists and animal caregivers are doing that work in the high-containment building, where they are outfitted with protective gear including respirators.
The experiment sprayed the virus into the udders and teats of two nursing cows after exposing four yearling heifers to a mist containing the virus. The first four infected cows showed minimal signs of illness. The other two grew increasingly ill, exhibiting decreased appetite, decreased lactation, and thick, yellowish milk.
According to health investigators’ understanding, the virus primarily spread through exposure to milk containing high levels of the virus. From there, it could spread through shared milking equipment or other means. However, Webby noted that it has occasionally been challenging to obtain comprehensive information from dairy farms, so it was crucial to complete the work.
“We didn’t really know how the virus was circulating, at best we had some good hunches,” he continued.
Scientists from the USDA are working on a different project, testing the blood of calves that drank raw milk for infections.
The virus was probably circulating for months before it was formally reported in Texas in March, according to a study done by the Iowa Center and several universities.
In addition, a novel and uncommon gene combination found in the bird flu virus was detected in the cows. According to Tavis Anderson, one of the study’s lead investigators, scientists are attempting to determine whether this gene combination allowed the virus to spread to or among cows.
Researchers at Ames anticipate years of work, either way.
In addition, Anderson asked, “Do they (cows) have their own unique influenzas? Can it go from a cow back into wild birds? Cow into a human? Cow into a pig?”. I believe the key research question, or at least one of them, is to comprehend those dynamics.
