Computational analysis of the receptor binding specificity of novel influenza A/H7N9 viruses

tailieu.vn

To date, it is not clear how the mutations of influenza viruses lead to the shift of host specificity, the increase of pathogenicity, and the ability of airborne transmission [8], all of which are taken as requirements for avian in- fluenza to cause pandemics. Su et al. Similarly, Pan et al. and Kannan et al. investigated the binding prefer- ences of A/H1N1 HA protein for different host cell re- ceptors, giving insight into the virulence enhanced by the HA mutation D222G [18, 19].

Genomic content of chemosensory genes correlates with host range in wood-boring beetles (Dendroctonus ponderosae, Agrilus planipennis, and Anoplophora glabripennis)

A recent study included the genomic annotations of the ORs of these two species in a large-scale analysis [53], but we here reanalyze them alongside the other che- mosensory genes in the context of host specificity. A previous study of the antennal transcriptome of D.. Our present study of the genome yielded a total of 254 chemosensory genes (Additional file 1: Table S1), of which 153 gene models.

DNA barcoding of black cherry aphid Myzus cerasi (Fabricus, 1775) (Hemiptera: Aphididae) populations collected from Prunus avium and Prunus cerasus

tailieu.vn

Likewise, Myzus cerasi samples collected mainly from Prunus avium and Prunus cerasus in Europe formed two major clades referring to two host-specific subspecies and the average genetic divergence of COI sequences between two clades was reported to be 0.2% (Rakauskas et al., 2014). However, contrary to the opinion on host specificity, oligophagous or polyphagous feeding patterns of black cherry aphid should be reassessed if we take into consideration that all the M.

Habitat structure and host plant specialization drive taxonomic andfunctional composition of Heteroptera in postfire successional habitats

tailieu.vn

Bugs show a wide range of host specificity towards their host plants, ranging from species feeding on a single plant (monophagous), a genus, or a family (oligophagous) to those that are highly polyphagous, feeding on multiple plant families (Carver et al., 1991). Torma et al . In the short term, fire reduces vegetation biomass, simplifies habitat structure (Keeley et al., 2012), and drives changes in faunal composition (Kelly and Brotons, 2017). the use of burnt vegetation (Bros et al., 2011).

Use of bacteriophages as a target specific therapy against food borne pathogens in food industry - a review

tailieu.vn

Phages offer an extreme specificity to target their bacterial host, one of the most significant advantages of bacterial pathogen biocontrol and because of their inherent host specificity, phages harbor a targeted antimicrobial approach without affecting the. Phages are consumed regularly via various foods because they form part of the natural microbial flora found in foods.. Postharvest controlling of the bacterial pathogens is a complex process.

The Insects - Outline of Entomology 3th Edition - Chapter 13

tailieu.vn

If all host–parasite relationships are examined, some of the factors that govern host-specificity can be identified:. the stronger the life-history integration with that of the host, the greater the likelihood of monoxeny;. the greater the vagility (mobility) of the parasite, the more likely it is to be polyxenous;. the number of accidental and secondary parasite species increases with decreasing ecological specializa- tion and with increase in geographical range of the host, as we saw earlier in

Prediction of pathogenicity genes involved in adaptation to a lupin host in the fungal pathogens Botrytis cinerea and Sclerotinia sclerotiorum via comparative genomics

tailieu.vn

In the broad host-range pathogen Coleosporium ipomoea, it has been postulated that isolates may narrow in host range towards host-specificity as they co-evolve with their respective hosts [19]..

A generalized approach to predicting protein-protein interactions between virus and host

tailieu.vn

Prediction models of virus-host PPIs. The performance of the prediction models were evalu- ated by several measures: sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), Matthews correlation coefficient (MCC) and the area under the ROC curve (AUC), which are defined as follows. RFAT: relative frequency of amino acid triplets. FDAT: frequency difference of amino acid triplets between virus and host proteins. AC: amino acid composition.
