Influenza A pandemic (H1N1) 2009 virus continues to rapidly spread worldwide. In 2009, pandemic (H1N1) 2009 infection in a domestic cat from Iowa was diagnosed by a novel PCR assay that distinguishes between Eurasian and North American pandemic (H1N1) 2009 virus matrix genes. Human-to-cat transmission is presumed.
After porcine epidemic diarrhea virus (PEDV) was detected in the United States in 2013, we tested environmental samples from trailers in which pigs had been transported. PEDV was found in 5.2% of trailers not contaminated at arrival, , suggesting that the transport process is a source of transmission if adequate hygiene measures are not implemented.
4 simultaneous Markov chains over 2 million generations, sampled every 100 generations, and ended with a calculation of a 50% majority rule consensus tree. On the phylogenetic tree, sequences of Estonian isolate group together with those of other E. multi-locularis isolates from different countries and were clearly separated from those of all other species… (More)
Porcine epidemic diarrhea virus (PEDV) was identified in the United States (U.S.) swine population for the first time in April 2013 and rapidly spread nationwide. However, no information has been published regarding the minimum infectious dose (MID) of PEDV in different pig models. The main objective of this study was to determine the oral minimum… (More)
Porcine deltacoronavirus (PDCoV) was detected in feces from diarrheic sows during an epidemic of acute and transmissible diarrhea. No transmissible gastroenteritis virus or porcine epidemic diarrhea virus was detected. The PDCoV USA/IA/2014/8734 from the herd was sequenced for full-length genomic RNA to further characterize PDCoV in U.S. swine.
BACKGROUND The emergence in humans of pandemic (H1N1) 2009 (pH1N1) with similarities to swine influenza viruses (SIVs) caused much concern for both human and animal health as potential for interspecies transmission was initially unknown. OBJECTIVES The goal of this study was to develop a real-time RT-PCR test for the detection and differentiation of 2009… (More)
A unique porcine circovirus type 2 capsid protein (ORF2) sequence was detected in swine samples submitted to the Iowa State University Veterinary Diagnostic Laboratory. The complete genome sequences of four viruses, one from Mexico and three from the United States, were determined to further characterize this novel PCV2 genotype.
The complete genome of sapelovirus A, formerly known as porcine sapelovirus (PSV), from a diarrheic pig was sequenced for the first time in the United States (designated PSV USA/IA33375/2015). It shares 87.8% to 83.9% nucleotide identities with other reported PSV strains globally and is most closely related to Asia PSV strains.
Since July 2015, vesicular lesions affecting growing pigs and sows accompanied with neonatal mortality have been reported in multiple U.S. states. Senecavirus A has been consistently detected from these cases. The complete genome sequences of 3 recent U.S. Senecavirus A isolates were determined to further characterize this virus.
