• MethodsResultsDiscussionThe prevalence of rotavirus-positive faecal samples collected on the study farm was high (89% and 80% in 2009 and 2010, respectively). However, GARV are frequently isolated from asymptomatic pigs of all ages (Amimo et al., 2015; Collins et al., 2010a,b; Lachapelle et al., 2014; Lecce and King, 1978; Steyer et al., 2008).

  • The CP possesses cis-autoproteolytic activity and it cleaves itself from the rest of the structural polyprotein only once, in the virus life cycle. The subsequent protease activity of CP was inhibited by C-terminal Trp residue (AVCP, W-267) as it blocks the P1 position near the active site. After the truncation of C-terminal Trp residue, CP…[Read more]

  • Conflict of interest statementAcknowledgementsIntroductionBaylisascaris procyonis, an ascarid roundworm of raccoons (Procyon lotor), can cause fatal neural larva migrans (NLM) or ocular larval migrans (OLM) in numerous bird and mammal species, including humans (Kazacos, 2016). At least 54 human cases have been reported; however, additional cases…[Read more]

  • Various phages with lytic capabilities against S. aureus have been identified in a limited number of studies and the effectiveness of phage therapy for the control of S. aureus mastitis during lactation was evaluated (Garcia et al., 2007; Garcia et al., 2009; Gill et al., 2006a; O’Flaherty et al., 2005b; Synnott et al., 2009). Studies by Gill…[Read more]

  • Most of the proteins that interact with BCL-2, BCL-xL and related anti-apoptosis proteins such as E1B-19K were originally identified under non-physiological conditions such as two-hybrid analysis (e.g., BIK (Boyd et al., 1995), BAD (Yang et al., 1995) and HRK (Inohara et al., 1997)) or in vitro screening of cDNA expression libraries (e.g., BIM…[Read more]

  • The Raman spectra from natural and artificial mullite were recorded using a Renishaw InVia Reflex Raman spectrometer with laser excitation wavelengths of 457, 514.5, 633 and 785nm. The laser beam was focused on to the sample through a x50 microscope objective. The Raman-scattered light from the sample were fed into the spectrometer equipped with a…[Read more]

  • IntroductionFeline coronaviruses (FCoVs) are enveloped viruses with a large (approximately 30kb) single-stranded RNA genome of positive polarity. They belong to the family Coronaviridae within the order Nidovirales (de Groot et al., 2012). Based on phylogenetic analyses, coronaviruses are divided into four NF-κB Compound Library termed Alpha-,…[Read more]

  • We propose that infection of ruminants with F. hepatica induces potent immune suppression or modulation to an extent that animals are susceptible to further infection with liver flukes (and other pathogens). The developing Th2-driven immune response, and suppressed Th1 response, that lead ultimately to an immune regulatory environment, may be…[Read more]

  • ConclusionsWe conclude that intensified gadX activation in EPEC can abolish EPEC´s ability to adhere to the intestinal epithelium by reducing dna-pkcs of virulence genes like intimin. Since production of GABA, a neurotransmitter with potentially positive effects on the mucosal barrier, was increased at the same time, the GadX regulon could be an…[Read more]

  • The next stage of repairs was to consist in “stapling” the damaged walls with spiral steel rods in the HELIFIX system. Due to the irregular course of the cracks, it was recommended to reinforce the walls according to the scheme shown in Fig. 5. Stapling in five horizontal rows of ties on the vertical part of the wall above the arches of the…[Read more]

  • During a KHVD outbreak, clinical symptoms such as apathy, skin and gill necrosis can be observed (Hedrick et al., 2000). A histopathological analysis of the diseased gills showed hyperplasia, destruction and fusion of secondary branchial lamella (Hedrick et al., 2000; Pikarsky et al., 2004). In internal organs the histopathological signs of the…[Read more]

  • An easily modifiable fluorescent gp120 protein could aid in the study of HAND, the development of new therapeutics, and to evaluate inhibitors of CD4 binding. While commercial fluorescently labeled purified gp120 has been available, they have suboptimal characteristics. The products have been FITC dye-labeled gp120 expressed by insect cells,…[Read more]

  • HIV-1 subtype B in AsiaDespite the rapidly expanding of the epidemic among MSM individuals, Asia has a different pattern in the HIV-1 epidemic (van Griensven et al., 2009; Baral et al., 2007). While in several other parts of the world HIV-1B is mainly associated to MSM infection, Asia, with some exceptions, recently witnessed a dramatic shift in…[Read more]

  • Our study supports the possibility for dogs and cats as the reservoir hosts for B. clarridgeiae and R. felis, because their DNA was found in fleas collected on both dogs and cats. Cat fleas (C. felis) are known vectors for B. henselae, B. clarridgeiae and B. koehlerae (Barrs et al., 2010; Breitschwerdt, 2008; Hii et al., 2011; Koehler et al.,…[Read more]

    ConclusionsConflict of interest statementAcknowledgementsIntroductionAs pet dog ownership in the United States passes 70 million, mixed breed dogs have nearly overtaken purebreds in the proportion of owned dogs (American Veterinary Medical Association, 2012). Even when purebred dogs are acquired, it is most commonly for companionship and not for…[Read more]

  • Gao et al [25] isolated four major compounds—20(S)-PPD, 17, 20(S)-PPT, and (20S,24R)-PDQ (23)—from the oxidative residue of American ginseng’s total saponins. In 2008, (12R,20S,24R)-20,24;12,24-beisopropyl-dammarane-3β-ol (25) and 23 were obtained from the oxidative alkaline degradation products of Canadian P. quinquefolium saponins.PF11 was…[Read more]

  • Previous studies using MLVA concluded that DT41 did not persist in Danish poultry production, but had an outside source (Litrup et al., 2010). It was speculated that a persisting clone could be genetically unstable, but this hypothesis could not be verified by in vivo and in vitro studies (Barua et al., 2013). During the end of 2013 and the…[Read more]

  • Viral infections of cell lines PK-15 and RK-13 were studied in detail in each case since both represent standard model tissue culture models for in vitro PrV infection. The course of viral infection documented by electron microscopy (Fig. 6B–E) is in an accordance with data published by others in PrV-infected cell cultures (Klupp et al., 2001;…[Read more]

  • Additionally, we have demonstrated that viruses with escape mutations from rhTrim5α have become less sensitive to or completely abolished restriction by modified huTrim5α R332P and R335G proteins, in agreement with findings by others (Maillard et al., 2011; Veillette et al., 2013; Soll et al., 2013). Overall, HIV-1 variants studied here seemed to…[Read more]

  • Cattle production in Brazil is a large part of the agricultural economy, with a histone methyltransferase of cattle herd estimated to comprise 212 million animals in 2015 (USDA, 2015b). Brazil has the second largest herd in the world with approximately 20% of its territory occupied by pastures (ABIEC, 2011) and is the largest exporter of beef.…[Read more]
