In January 2014, approximately 9 months following the initial detection of porcine epidemic diarrhea (PED) in the USA, the first case of PED was confirmed in a swine herd in south-western Ontario. A follow-up epidemiological investigation carried out on the initial and 10 subsequent Ontario PED cases pointed to feed as a common risk factor. As a result, several lots of feed and spray-dried porc...

in this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. the model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. by using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. ...

The full-length genome sequence of a variant porcine epidemic diarrhea virus (PEDV) strain, CH/GDZQ/2014, was determined. The isolate was a variant strain with a relatively far relationship with the PEDV strains previously identified in the same area between 2011 and 2012 and was genetically distinct from the CV777-based vaccine strain currently being used in China.

Epidemic keratoconjunctivitis is usually caused by infection with an adenovirus, generally type 8 (Hanna, Jawetz, Mitsui, Thygeson, Kimura, and Nicholas, I957). As this is a DNA virus it might be expected to respond to treatment with 5-iodo-2'-deoxyuridine (IDU) which acts by interfering with the normal synthesis of DNA, thus preventing replication of DNA-containing viruses (Herrmann, I 96 I; S...

Porcine epidemic diarrhea virus (PEDV) strain CHYJ130330 was isolated from southern China and shown to be highly virulent when inoculated into neonatal pigs. This report describes the complete genome sequence of CHYJ130330. These data will provide important insights into the variation of PEDV in China.

In March of 2014, a variant of novel porcine epidemic diarrhea virus (PEDV) was first identified in South Korea and found to be most closely related to the U.S. variant strain OH851. The complete genome of the KOR/KNU-1406/2014 strain was sequenced and analyzed to investigate the U.S.-strain-like variant circulating in South Korea.

To investigate the evolutionary process by which porcine epidemic diarrhea virus (PEDV) in the United States hypothetically descended from strains in China, we analyzed PEDV-positive samples collected in China during January 2012-July 2013. Recombination in 2 strain sublineages was likely associated with identification of PEDV in the United States in 2013.

Nationwide porcine epidemic diarrhea virus (PEDV) outbreaks occurred in late 2013 in the Republic of Korea, resulting in an expansion of genomic data for Korean PEDVs. However, the data available for Korean PEDVs before 2013 are insufficient. Therefore, we sequenced and analyzed the complete genome of a Korean PEDV strain, KUPE21, which was isolated in the early 2000s.

Porcine epidemic diarrhea virus (PEDV) has continued to cause sporadic outbreaks in Thailand since 2007. Previously, PEDV in Thailand was a new variant containing an insertion and deletion in the spike gene. Herein, full-length genome sequences are reported for two variants of PEDV isolates from pigs displaying diarrhea in Thailand.
