- summary: A striking change in the expected relative or absolute abundance of viral RNA of a given sense may provide clues as to the mode of viral replication in vitro or of viral pathogenesis in vivo. However, in many experiments, particularly with samples obtained in vivo, viral RNA may not be of sufficiently high concentration to allow detection by this technique.

- flesch: 38
- summary: The assay was designed to detect all known RSV strains and to differentiate RSV subgroups A and B. Primers (MTH1 and MTH2B) were selected using Primer Express software v2.0 (Applied Biosystems Inc., Foster city (CA), USA) and a dataset of 45N gene sequences available from the NCBI database (Table 1) to amplify 84 bp for both RSV A and RSV B. RSV subgroups No significant differences in RSV viral load were observed between patients with single infections versus co-infections, or between patients requiring oxygen versus patients who did not.

In the case the sensitivity of the test might be ameliorated through further studies, the RT-LAMP could be extremely useful, due to its low costs and rapidity, in those situations where the Table 2 Results obtained on the samples tested with RT-nPCR (PCR) and LAMP and evaluated with agarose gel electrophoresis (LAMP GEL) and hydroxynaphtol blue dye (LAMP HNB detection of FCoV must be repeated over time and on a high number of cats (e.g. breeding catteries).

However, in both assays the relative peak-height provides information on the viral load compared to that of the internal control and between multiple virus detections.

- summary: On the basis of the significant genetic differences between the reference and the Elmo/02-like CCoVs our tentative proposal is to designate the new genotype identified as CCoV type I, and to designate the reference strains, such as Insavc-1 and K378, as CCoVs type II. In a previous study, sequence analysis of CCoVs detected in faecal samples collected from dogs with diarrhoea revealed multiple nucleotide substitutions accumulating over a fragment of the M gene (Pratelli et al., 2001) .

- summary: The CCoV fluorogenic RT-PCR assay, which targeted the ORF5 (M gene), was more sensitive than a conventional RT-PCR assay targeting the same gene, showing a detection limit of 10 copies of CCoV standard RNA, and was linear from 10 to 10(8) copies, allowing quantitation of samples with a wide range of CCoV RNA loads. Several RT-PCR based methods have been developed for detecting CCoV RNA in the faeces of dogs, but none of these were designed to be quantitative (Bandai et al., 1999; Naylor et al., 2001; Pratelli et al., 1999 Pratelli et al., , 2002c .

- summary: In addition, serologic assays to detect antibodies to RTV in rats have historically used mouse TMEV strains as antigens, exploiting the antigenic cross-reactivity of these viruses with RTV (Easterbrook et al., 2008; Pritchett-Corning et al., 2009) . In the presence of 1 × 10 6 copies/ng of RTV genomic RNA, the TMEV standard curves were similar to those generated from the standard dilutions alone (Fig. 5A) .

Incorporating a second consensus primer into the assay produced a multiplex PCR that provided Orthopoxvirus generic and variola-specific products with variola virus DNA.

- summary: Although the influenza A/H1N1/2009 virus is likely to become the predominant influenza A type encountered in most countries, seasonal influenza A types may also co-circulate (Kelly et al., 2009) and in some countries sporadic H5N1 infections may still occur (WHO report of Avian influenza, 2009). Determining the subtype of influenza virus is important as it has implications for patient management and infection control (Meijer et al., 2009; Beigel and Bray, 2008; This panel contained examples of seasonal influenza A, H1N1 and H3N2, the influenza A/H1N1/2009 and numerous avian A/H5N1 viruses.

Furthermore, we compared the seroprevalence of CVB3 NtAbs in pre-school children and healthy adults, and found that only 11.94% of pre-school children were NtAbs positive which suggested that most children were naive to CVB3 infection; while there is much higher positive rate in adults (60%) indicating that most adults have experienced CVB3 infection during childhood.

- flesch: 41
- summary: The expression of ARV proteins σC, σA, and σNS was also reduced markedly, suggesting that suppression of virus replication is due to down-regulation of these ARV proteins by ubiquitin-proteasome system. A recent report demonstrated that p53 regulates bax expression and translocation into the mitochondria leading to cytochrome c release into the cytoplasm, activating the caspase pathway that finally leads to cell apoptosis (Chulu et al., 2007) .

The CV777 strain of PEDV, kindly provided by Maurice Pensaert at Ghent University (Merelbeke, Belgium), was used in all of our experiments after being adapted to Vero E6 cells, as previously described (Hofmann and Wyler, 1988) .

- summary: In contrast to conventional singleplex real time RT-PCR, the triplex real time RT-PCR that we have developed in this present study can be used to monitor PHEV genotypes and potentially to identify new variants if test results cannot be explained as expected. The sensitivity of the triplex rRT-PCR was determined through 10fold serial dilutions of RNAs of known PHEV genotypes (15SW1362 for G123 and G13, and 15SW25049 for G3) and plasmids pCR 2.1-15SW1582-N for G123, pCR 2.1-15SW1362-NS2 for G13, and pCR 2.1-15SW25049-NS2 for G3 in duplicate.

- summary: The M protein of PEDV protrudes from the viral envelope, and is considered a superior diagnostic antigen compared with other PEDV proteins (Shenyang et al., 2007) . The nucleotide sequence of the PEDV M gene exhibits low homology (around 50%) with the M gene of other coronaviruses; however, its sequence is highly conserved among different PEDV strains Arndt et al., 2010) .

Although many attempts have been made either to improve the antigen-producing properties of existing permanent bovine leukosis virus (BLV) expressing cell lines or to generate corresponding new lines (Graves and Ferrer, 1976; Mamoun et al., 1981; Altaner et al., 1985; Altanerova et al., 1989; Wagner et al., 1995) , the cell line FLK/BLV still is the one that is used mainly for BLV antigen production for commercial diagnostic test kits.

- date: 2015-03-23
- words: 3465
- flesch: 39
- summary: Previous studies used silver and gold electrodes as QCM biosensors (Kim et al., 2014; Su et al., 2000) ; however, gold electrodes produce more consistent results because the surface is less rough than that of silver (Su et al., 2000) . Many studies have used the QCM biosensor to detect pathogenic microorganisms such as Vibrio cholerae, Bacillus anthracis, malaria, Salmonella Typhimurium, Leishmania infantum, and canine influenza virus (Cabral-Miranda et al., 2014; Carter et al., 1995; Cooper et al., 2001; Hao et al., 2009; Ittarat et al., 2013; Kim et al., 2014; Salam et al., 2013) .

- date: 2010-08-04
- words: 2774

- summary: En et al. (2008) described a LAMP system for PRV detection but that LAMP system could not differentiate between swine infected with wild-type PRV and swine vaccinated with PRV gE-deleted. The use of LAMP is described for determining whether swine are infected with wild-type PRV or have been vaccinated with PRV gE-and remain uninfected by wild-type strains.

- date: 2017-06-17
- words: 6663
- flesch: 36
- summary: Drying time for enteric virus surface sampling is highly variable and dependent on factors including volume of virus suspension and desiccation (Table 1) . For instance, stainless steel is a hydrophilic (contact angle of 58.2°in water, surface energy of 50.3 mJ/m 2 ) and negatively charged surface in which microorganisms have been shown to develop irreversible attachment within one minute potentially making surface recovery more difficult (Mafu et al., 1990; Mafu et al., 1991) .

- date: 2009-12-17
- words: 4171
- flesch: 40
- summary: In that case, two consequences will be obvious: first, a reservoir of H1N1 virus in the swine population poses an elevated risk for human infection via aerosol transmission from clinically ill pigs, and second, dramatic economic losses for the pork industry due to direct disease related costs as well as indirect market losses. Although the 2009 H1N1 is related genetically to swine influenza viruses, human infection has not been connected to pig exposure.

- date: 2017-03-21
- words: 5022
- flesch: 43
- summary: Conventional RT-PCRs amplifying hypervariable regions (HVRs 1–2 and 3) of the IBV S1 gene were developed and amplificates used for nucleotide sequence-based typing of IBV field strains in Egyptian chickens directly from clinical samples. No RT-PCR amplicates were obtained from two further samples that showed Cq values <32 in IBV RT-qPCR; failure to amplify IBV S1-specific RNA from these samples may be related to advanced RNA degradation.
