We report for the first time in the United States the identification of a swine pasivirus (SPaV) strain with a genomic sequence identity of less than 80% to other SPaVs reported in Europe and China, using a next-generation sequencing (NGS) technique in sow tissues collected from an animal study conducted in 2001, suggesting virus circulation in domestic swine.

A porcine parainfluenza virus type 1 (species Porcine respirovirus 1 ) cell culture isolate, USA/MN25890NS/2016, was obtained from porcine nasal swabs, and its complete genome sequence (GenBank accession number MF681710) was determined to help further characterize this virus.

Avian-pathogenic Escherichia coli (APEC) is the causative agent of colibacillosis, a disease that affects all facets of poultry production worldwide, resulting in multimillion dollar losses annually. Here, we report the genome sequence of an APEC O18 sequence type 95 (ST95) strain associated with disease in a chicken.

Neonatal meningitis Escherichia coli (NMEC) is a common agent of neonatal bacterial meningitis, causing high neonatal mortality and neurologic sequelae in its victims. Here, we present the complete genome sequence of NMEC O18 (also known as NMEC 58), a highly virulent (O18ac:K1, ST416) strain.

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.

A high-passage rabbit kidney RK-13 cell line (HP-RK-13[KY], originally derived from the ATCC CCL-37 cell line) used in certain laboratories worldwide is contaminated with noncytopathic bovine viral diarrhea virus (ncpBVDV). On complete genome sequence analysis, the virus strain was found to belong to BVDV group 1b.

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.

Colibacillosis, caused by avian pathogenic Escherichia coli (APEC), is a significant disease, causing extensive animal and financial losses globally. Because of the significance of this disease, more knowledge is needed regarding APEC's mechanisms of virulence. Here, we present the fully closed genome sequence of a typical avian pathogenic E. coli strain belonging to the serogroup O78.
