Infections with bacteria of the species YERSINIA PSEUDOTUBERCULOSIS.

A human and animal pathogen causing mesenteric lymphadenitis, diarrhea, and bacteremia.

Infections with bacteria of the genus YERSINIA.

A species of gram-positive, asporogenous bacteria that was originally isolated from necrotic areas in the kidney of a sheep. It may cause ulcerative lymphangitis, abscesses, and other chronic purulent infections in sheep, horses, and other warm-blooded animals. Human disease may form from contact with infected animals.

Infections with bacteria of the genus CORYNEBACTERIUM.

A species of the genus YERSINIA, isolated from both man and animal. It is a frequent cause of bacterial gastroenteritis in children.

A genus of gram-negative, facultatively anaerobic rod- to coccobacillus-shaped bacteria that occurs in a broad spectrum of habitats.

The etiologic agent of PLAGUE in man, rats, ground squirrels, and other rodents.

The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.

An acute infectious disease caused by YERSINIA PESTIS that affects humans, wild rodents, and their ectoparasites. This condition persists due to its firm entrenchment in sylvatic rodent-flea ecosystems throughout the world. Bubonic plague is the most common form.

Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. What is sometimes called polymeric adhesin (BIOFILMS) is distinct from protein adhesin.
