The H5N1 bird flu in dairy and commercial poultry is low in the United States, but scientists continue to classify the way the virus spreads to the farm, and this week, two new information is shining more light on the potential spread of dairy products.
In the last 30 days, the US Department of Agriculture (USDA) has only reported only one detection. poultryTwo detections in Dairy Cows with a group of game bird farms in Pennsylvania and a group of California and Arizona.
The decrease in US detection seems to be part of a seasonal decline. New monthly Update The World Animal Health Organization (WOAH), which deals with the activities of June, said that the occurrence of poultry has decreased, but reported in 15 months, especially in Europe, new outbreaks of wild birds are increasing.
In the early stages of H5N1 in dairy cows, the movement of infected cows and contaminated equipment was considered to play a big role in the spread of viruses. However, despite the curb that moves dairy cows among the states, the onset continued to occur and strengthened biological security measures for farms, raising intense scientific investigations on continuous questions and other contribution factors.
The flight sequence stirs a new buzz
Earlier this week, Raj Rajnarayanan, MSC, and PHD, the calculators of the College of Osteoporosis of the New York Technology Research Institute of Arkansas State University, have recently uploaded the H5N1 sequence samples of California’s House of Representatives in October, and have a global initiative with all influence. It was uploaded to in GISAID, and Global Initiative about his observation discovered his observation. X. Like the virus spreading to the cow, the virus belonged to the B3.13 lower type of 2.3.4.4b clad.
Rajnarayanan said in a subsequent post, “As a result of finding avian influenza in the house Paris, the insect shows that the virus can move mechanically around the farm.” There is no evidence of spreading H5N1 to humans or animals, but another reason for strengthening farm biology security! “
MIKE COSTON, the cause of all paramedics who have recorded bird flu science development for decades on his news blog Bird flu diaryA mail Yesterday showed that in 2006, the hit flies found near poultry in Japan could be carried with viruses, contacting infected materials and spreading with feet or body.
“We are not talking classically ‘Infected“Paris, polluted flies can be one of many contributors who have contributed to the spread of the HPAI virus,” he wrote, and pointed out the latest prefrint studies that proposed a blow in the Japanese crane colonies, allowing the virus from the feces of dead birds or infected birds.
Coston also mentioned that ferry -stick animals such as rodents and poultry dust were proposed as other contributors. “And the ability to slow or include these development speeds will still be limited until we deal with how HPAI spreads between the wild and the farm.”
‘Milk Coaching’ in the path of cow wired infection
In other developments, a Chinese research team, which studied experimental infections related to the transmission of other inoculation paths and dairy cattle, found that the transmission of the entrance taxi could be a method of infecting the H5N1 virus at first. The team announced the results early this month. National Science Review.
They are replicated by the virus delivered through the nose only in the mouth and only in the respiratory tract of the dairy cattle, but the inoculation to the wired is replicated only on the wire.
Since some nursing cows are “stealing milk” through self -monitoring or mutual care, the enlistment may be a path in which H5N1 first infects the wire, the team said. The calf was also able to spread the virus through nursing. Researchers include high levels of poetic acid receptors in small oral tissues, which can promote viral infections through contaminated feeds and water and promote efficient replication that can last for several days.
In other experiments, the researchers tested two vaccines, H5 fire -activated vaccines and Haymaglutinin -based DNA vaccines in lactation cattle. They found that both of them were directly wired and gave full protection of H5N1 after the high -dose virus challenge.
