Appearance of reassortant European avian ‐origin H1 influenza A viruses of swine in Vietnam
Summary Three subtypes—H1N1, H1N2 and H3N2—of influenza A viruses of swine (IAVs‐S) are currently endemic in swine worldwide, but there is considerable genotypic diversity among each subtype and limited geographical distribution. Through IAVs‐S monitoring in Vietnam, two H1N2 influenza A viruses were isolated from healthy pigs in Ba Ria‐Vung Tau Province, Southern Vietnam, on 2 December 2016. BLAST and phylogenetic analyses revealed that their HA and NA genes were derived from those of European avian‐like H1N2 IAVs‐S that contained avian‐origin H1 and human‐like N2 genes, and were particularly closely rel...

Detection of bovine coronavirus in nasal swab of non ‐captive wild water deer, Korea
Summary Bovine coronavirus (BCoV) is a causative agent of respiratory and enteric diseases in cattle and calves. BCoV infection was also evident in captive wild ruminants. Recently, water deer are recognized as the most common wildlife to approach farmhouses and livestock barns in Korea. Therefore, we investigated 77 nasal swab samples from non‐captive wild water deer (Hydropotes inermis) between November 2016 and September 2017 and identified three samples positive for coronavirus, indicating potential for respiratory shedding. The full genomic sequences of the water deer coronavirus were closely related to BCoV (>9...

Rapid specific and visible detection of porcine circovirus type 3 using loop ‐mediated isothermal amplification (LAMP)
In this study, a rapid and specific assay for the detection of porcine circovirus type 3 (PCV3) was established using loop‐mediated isothermal amplification (LAMP). Four primers were specifically designed to amplify PCV3. The LAMP assay was effectively optimized to amplify PCV3 by water bath at 60°C for 60 min. The detection limit was approximately 1 × 101 copy in this LAMP assay. Compared to porcine circovirus type 2 (PCV2), both gE and gD genes of pseudorabies virus (PRV) and porcine parvovirus (PPV), the LAMP assay showed a high specific detection of PCV3. A visible detection method was developed using SYBR Green...

Spatio ‐temporal patterns of foot‐and‐mouth disease transmission in cattle between 2007 and 2015 and quantitative assessment of the economic impact of the disease in Niger
This study provided also a first report on economic losses associated with FMD. From 2007 to 2015, 791 clinical FMD outbreaks were reported from the eight regions of Niger, with the number of outbreaks per region ranging from 5 to 309. The statistical analysis revealed that three regions (Dosso, Tillabery and Zinder), the months (September, corresponding to the end of rainy season, to December and January, i.e., during the dry and cold season), the years (2007 and 2015) and the density of contact were the main predictors of FMD occurrence. The quantitative assessment of the economic impacts showed that the average total co...

Phylogenetic analysis of ORF5 and ORF7 of porcine reproductive and respiratory syndrome (PRRS) virus and the frequency of wild ‐type PRRS virus in México
In this study, a total of 8,126 serum samples were obtained from 275 technified and semi‐technified farms belonging to 30 of the 32 states of Mexico and representative of the eight regions of the country. Anti‐PRRSv antibodies against the PRRS vaccine and an isolated wild Mexican virus were tested by ELISA. Antibodies were found in 15%–49% of the tested sera, with 2.4%–9.8% against the vaccine and 7.7%–26% against the wild virus. The PRRSv virus was detected by RT‐PCR in 77 of the 1,630 pooled samples tested, representing seven of the eight geographic regions into which the Mexican Republic is divided. The comp...
