The objective of this study was to estimate heritabilities for and genetic correlations among different pathogen-specific mastitis traits. The traits were unspecific mastitis, which is all mastitis treatments regardless of the causative pathogen as well as mastitis caused by Streptococcus dysgalactiae, Escherichia coli, coagulase-negative staphylococci (CNS), Staphylococcus aureus and Streptoco...

The acquisition of a virulence plasmid is sufficient to turn a beneficial strain of Rhodococcus bacteria into a pathogen.

OBJECTIVE Bacteria- and fungus-binding mesh traps and inactivates bacteria and fungus, which makes it interesting, alternative, and wound filler for negative pressure wound therapy (NPWT). The aim of this study was to compare pathogen-binding mesh, black foam, and gauze in NPWT with regard to granulation tissue formation and ingrowth of wound bed tissue in the wound filler. METHODS Wounds on ...

Probiotic microorganisms have attracted a growing interest for prevention and therapy of gastrointestinal disorders. Many probiotic strains have been shown to inhibit growth and metabolic activity of enteropathogenic bacteria as well as their adhesion and invasion to intestinal cells. In the present study, we evaluated the interference of bacteria-free supernatants (BFS) of cultures belonging t...

Vibrio parahaemolyticus is a food-borne pathogen that naturally inhabits both marine and estuarine environments. Free-living protozoa exist in similar aquatic environments and function to control bacterial numbers by grazing on free-living bacteria. Protozoa also play an important role in the survival and spread of some pathogenic species of bacteria. We investigated the interaction between the...

Pathogen-induced reorganization of the host cell cytoskeleton is a common strategy utilized in host cell invasion by many facultative intracellular bacteria, such as Shigella, Listeria, enteroinvasive E. coli and Salmonella. Shigella is an enteroinvasive intracellular pathogen that preferentially infects human epithelial cells and causes bacillary dysentery. Invasion of Shigella into intestinal...

Bacteremia in immunocompromised hosts often arises from their endogenous intestinal flora. We produced experimental endogenous bacteremia by administering cyclophosphamide and ampicillin to conventional and specific-pathogen-free mice. The frequencies of bacteremia and mortality in the conventional mice were significantly higher than for the specific-pathogen-free mice. Pseudomonas aeruginosa w...

Background & Aims: Acinetobacter spp. are non-fermenting gram-negative coccobacilli that have emerged in recent three decades as major causes of nosocomial infections. Acinetobacter baumannii is the most common pathogen causing a wide spectrum of infections. Acinetobacter infections are difficult to treat, due to both the intrinsic resistance of the pathogen and its ability to readily acquire n...
