Evolution of virulence in malaria [PDF]
Journal of Biology, 2008 The pathogenesis of severe malarial disease is not yet fully understood. It is clear that host immunopathology plays a central role, and a recent paper in BMC Evolutionary Biology suggests that the ability of the parasite to stimulate interleukin-10 production is a major factor and speculates on its impact on the coevolution of host and parasite.

Temporal dynamics of the fecal microbiota in veal calves in a 6-month field trial
Animal Microbiome, 2020 Background Little is known about maturation of calves’ gut microbiome in veal farms, in which animals are confined under intensive-farming conditions and the administration of collective antibiotic treatment in feed is common.

Extensive genomic diversity and selective conservation of virulence determinants in enterohemorrhagic Escherichia coli strains of O157 and non O157 serotypes [PDF]
, 2007 Background: Enterohemorrhagic Escherichia coli (EHEC) O157 causes severe food-borne illness in humans. The chromosome of O157 consists of 4.1 Mb backbone sequences shared by benign E.

Animals, 2021 Antibiotics are major disruptors of the gastrointestinal microbiota, depleting bacterial species beneficial for the host health and favoring the emergence of potential pathogens. Furthermore, the intestine is a reactor of antibiotic resistance emergence,

Frontiers in Microbiology, 2021 Poultry and poultry meat are important contributors to the global antimicrobial burden. Unregulated and illegal use of extended-spectrum cephalosporins (ESC) in this sector has long been identified as a major cause of massive spread of ESC-resistant ...

When is a bacterial “virulence factor” really virulent? [PDF]
, 2016 ABSTRACTBacterial traits that contribute to disease are termed ‘virulence factors’ and there is much interest in therapeutic approaches that disrupt such traits. However, ecological theory predicts disease severity to be multifactorial and context dependent, which might complicate our efforts to identify the most generally important virulence factors ...

The distribution of plasmids that carry virulence and resistance genes in Staphylococcus aureus is lineage associated. [PDF]
, 2012 BACKGROUND: Staphylococcus aureus is major human and animal pathogen. Plasmids often carry resistance genes and virulence genes that can disseminate through S. aureus populations by horizontal gene transfer (HGT) mechanisms. Sequences of S.

IsaB Inhibits Autophagic Flux to Promote Host Transmission of Methicillin-Resistant Staphylococcus aureus. [PDF]
, 2015 Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a major nosocomial pathogen that is widespread in both health-care facilities and in the community at large, as a result of direct host-to-host transmission.
