The highly pathogenic avian influenza (HPAI) H5N1 virus clade 2.3.4.4b has caused the death of millions domestic birds and thousands wild in USA since January 2022 (refs.
Abstract Highly pathogenic avian influenza (HPAI) viruses cross species barriers and have the potential to cause pandemics. In North America, HPAI A(H5N1) related goose/Guangdong 2.3.4.4b hemagglutinin phylogenetic clade infected wild birds, poultry, mammals. Our genomic analysis epidemiological investigation showed that a reassortment event in bird populations preceded single bird-to-cattle transmission episode. The movement of asymptomatic cattle has likely played role spread within United...
Infections with the highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b virus have resulted in death of millions domestic birds and thousands wild U.S. since January, 2022. Throughout this outbreak, spillovers to mammals been frequently documented. Here, we report detection HPAI dairy cattle herds across several states The affected cows displayed clinical signs encompassing decreased feed intake, altered fecal consistency, respiratory distress, milk production abnormal milk....
Salmonella Dublin infections in heifer-raising operations (HROs) cause animal health and economic losses for these represent a pathogen source dairy farms obtaining replacement heifers from HROs. To improve control of S. Dublin, we (i) developed mathematical model transmission on HRO, (ii) evaluated the vaccine effectiveness cleaning improvements controlling infection, (iii) influence infection strategies HRO's operating income. We modified Susceptible-Infected-Recovered-Susceptible spread...
<title>Abstract</title> We investigated the impact of influenza A-H5N1 virus infection in a dairy herd. Clinical disease, which lasted for about three weeks, was recorded 20.0% (777/3,876) adult cows. Milk losses ~900 kg per cow were affected cows during 60 day-post-outbreak period. Seroprevalence 89.4% (570/637) herd, with 76.1% (485/637) seropositive animals being subclinically infected. Clinically presented an increased risk death (6 times) and premature herd removal (3.6 times), when...
Abstract Objective To analyze the results and metadata of canine, feline, equine respiratory PCR panel assays performed at New York State Animal Health Diagnostic Center inform veterinary diagnostic sample submission. Methods This retrospective study reviewed laboratory data from routine submissions to for panels January 1 through December 31, 2023. Associations were compared between variables using χ 2 tests independence or Fisher exact tests. Results A total 1,902 (705 189 1,008 equine)....
Brucella canis is a zoonotic bacterial pathogen of dogs that notoriously difficult to diagnose and treat. Humans can become infected with B when an pet dog brought into their home. Our objectives were describe the clinical presentation outcomes in treated for evaluate performance quantitative serologic canine multiplex (CBM) assay monitoring treatment response.Diagnostic records from Animal Health Diagnostic Center at Cornell University retrospectively reviewed (2017-2022) underwent repeat...
Thirty-four Holstein calves from multiple farms were found recumbent during the neonatal period with no detectable neurologic, infectious, or metabolic abnormalities. Most did not survive beyond 6 wk of age. The objective this study was to conduct a genome-wide association and pedigree analysis determine if genetic origin plausible. There 101,917 DNA markers for 18 affected 26 unaffected family controls available analysis. Genome-wide association, homozygosity screening, parental based...
Twenty-eight lactating dairy cattle in New York State were exposed to botulism toxin; 12 died and 16 recovered but never returned full productivity. Pieces of a raccoon carcass found the total mixed ration on first day outbreak. Clinical signs included anorexia, decreased milk production, tongue tone, profound weakness, recumbency. Clostridium botulinum type A (BoNT/A) was detected rumen contents from 2 deceased cows via matrix-assisted laser desorption/ionization time-of-flight mass...
Salmonella Dublin is a zoonotic, multi-drug-resistant bacteria. It host adapted in cattle, and carrier animals shed bacteria feces milk, acting as reservoir for the herd. causes septicemia young calves, who present with high fever, increased respiratory effort acute death. Diagnosing an acutely infected calf requires aseptic collection of blood culture sample, storage at room temperature or incubator, overnight delivery to veterinary diagnostic laboratory. Diagnosing post-mortem submission...
