Exploring the Dynamics of Virulent and Avirulent Aphids: A Case for a "Within Plant" Refuge [PDF]
, 2021 The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is an invasive pest that can cause severe yield loss to soybeans in the northcentral United States. A tactic to counter this pest is the use of aphid-resistant soybean varieties. However, the occurrence of virulent biotypes can alter plant physiology and impair the use of this management ...

Helicobacter pylori virulence factors in duodenal ulceration: A primary cause or a secondary infection causing chronicity [PDF]
, 2006 Reports from countries with a high prevalence of Helicobacter pylori. (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration, suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It

Identification and characterisation of enteroaggregative Escherichia coli subtypes associated with human disease [PDF]
, 2020 Enteroaggregative E. coli (EAEC) are a major cause of diarrhoea worldwide. Due to their heterogeneity and carriage in healthy individuals, identification of diagnostic virulence markers for pathogenic strains has been difficult.

The evolution of virulence in RNA viruses under a competition-colonization trade-off [PDF]
Bull Math Biol, 2010, 2010 RNA viruses exist in large intra-host populations which display great genotypic and phenotypic diversity. We analyze a model of viral competition between two different viral strains infecting a constantly replenished cell pool, in which we assume a trade-off between the virus' colonization skills (cell killing ability or virulence) and its local ...

Passaging of a Newcastle disease virus pigeon variant in chickens results in selection of viruses with mutations in the polymerase complex enhancing virus replication and virulence [PDF]
, 2010 Some Newcastle disease virus (NDV) variants isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) do not show their full virulence potential for domestic chickens but may become virulent upon spread in these animals.

Effect of efflux pump inhibition on Pseudomonas aeruginosa transcriptome and virulence [PDF]
, 2017 Efflux pumps of the resistance-nodulation-cell-division (RND) family increase antibiotic resistance in many bacterial pathogens, representing candidate targets for the development of antibiotic adjuvants.

Is methicillin-susceptible Staphylococcus aureus (MSSA) CC398 a true animal-independent pathogen?
Journal of Global Antimicrobial Resistance, 2022 Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) belonging to ST398 has been widely described in animals. In parallel, methicillin-susceptible (MSSA) ST398 isolates causing severe infections in humans have recently emerged as animal ...

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]
, 2018 Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

Pathogenesis and virulence of flavivirus infections
Virulence, 2021 The Flavivirus genus consists of >70 members including several that are considered significant human pathogens. Flaviviruses display a broad spectrum of diseases that can be roughly categorised into two phenotypes – systemic disease involving haemorrhage
