Clonal Origin, Virulence Factors, and Virulence [PDF]
Infection and Immunity, 2000 The recent report from Picard et al. regarding extraintestinal Escherichia coli infections provides new insights into the relationships between clonal origin, virulence factor repertoire, and virulence (1). That clonal origin was only secondarily associated with virulence in this study was suggested by the finding that although mouse lethality was more

Virulence of enterococci [PDF]
Clinical Microbiology Reviews, 1994 Enterococci are commensal organisms well suited to survival in intestinal and vaginal tracts and the oral cavity. However, as for most bacteria described as causing human disease, enterococci also possess properties that can be ascribed roles in pathogenesis.

Parasite variation and the evolution of virulence in a Daphnia-microparasite system [PDF]
, 2008 Understanding genetic relationships amongst the life-history traits of parasites is crucial for testing hypotheses on the evolution of virulence. This study therefore examined variation between parasite isolates (the bacterium Pasteuria ramosa) from the ...

The central metabolism regulator EIIAGlc switches Salmonella from growth arrest to acute virulence through activation of virulence factor secretion [PDF]
, 2014 The ability of Salmonella to cause disease depends on metabolic activities and virulence factors. Here, we show that a key metabolic protein, EIIAGlc, is absolutely essential for acute infection, but not for Salmonella survival, in a mouse typhoid fever ...

A Relevant Wound-Like in vitro Media to Study Bacterial Cooperation and Biofilm in Chronic Wounds
Frontiers in Microbiology, 2022 Biofilm on the skin surface of chronic wounds is an important factor in the pathology, inhibiting wound healing. The polymicrobial nature of these infected wounds and bacterial interactions inside this pathogenic biofilm are the keys for understanding ...

Evolution, 1994 Why do parasites harm their hosts? Intuition suggests that parasites should evolve to be benign whenever the host is needed for transmission. Yet a growing theoretical literature offers several models to explain why natural selection may favor virulent parasites over avirulent ones.

Role of glucose and CcpA in capsule expression and virulence of Streptococcus suis [PDF]
, 2011 Streptococcus suis is one of the most important pathogens in pigs and is also an emerging zoonotic agent. After crossing the epithelial barrier, S. suis causes bacteraemia, resulting in meningitis, endocarditis and bronchopneumonia.

Virulence Attributes of Low‐Virulence Organisms [PDF]
Infectious Diseases in Obstetrics and Gynecology, 1994 The vast majority of infections involving female pelvic structures arise from organisms that are members of the normal flora. In addition, exogenous organisms that invade through the lower genital tract must interact with organisms that are part of the host′s flora.
