Actinomycosis vs. Actinobacillosis — What's the Difference?

Actinomycosis is a rare infectious bacterial disease caused by Actinomyces species. The name refers to ray-like appearance of the organisms in the granules.

Actinobacillosis is a zoonotic disease caused by Actinobacillus.It is more commonly associated with animals than with humans.One of the most common forms seen by veterinarians is mouth actinobacillosis of cattle, due to Actinobacillus lignieresii. The most prominent symptom is the swelling of the tongue that protrudes from the mouth and is very hard at palpation ("wooden tongue").

An inflammatory disease of cattle, hogs, humans, and other mammals, caused by actinomyces and characterized by lumpy tumors of the mouth, neck, chest, and abdomen. Also called lumpy jaw.

(pathology) A zoonotic disease, most commonly associated with animals, caused by the Actinobacillus bacteria, and which forms radiating structures in the tissues

(pathology) An infectious bacterial disease of cattle and swine, sometimes transmitted to man, characterized by the formation of painful abscesses in the mouth, lungs, or gastrointestinal tract, caused by Actinomyces israelii, Actinomyces gerencseriae, and Propionibacterium propionicum.

A chronic infectious disease of cattle and man due to infection with actinomycetes, especially by Actinomyces bovis in cattle and by Actinomyces israeli or Arachnia propionica in man. It is characterized by hard swellings usually in the mouth and jaw. In man the disease may also affect the abdomen or thorax. Called also lumpy jaw or big jaw.

Disease of cattle that can be transmitted to humans; results from infection with actinomycetes; characterized by hard swellings that exude pus through long sinuses
