Brucella abortus enters phagocytes that invade human and animal innate defenses which in turn, cause chronic disease in the host. The liver and spleen are the mainly affected areas of the body. [3] Farm workers and veterinarians are the highest risk individuals for acquiring the disease due to their close proximity to the animals.
Brucellosis [4] is a zoonosis caused by ingestion of unpasteurized milk from infected animals, or close contact with their secretions. [5] It is also known as undulant fever, Malta fever, and Mediterranean fever. [6] The bacteria causing this disease, Brucella, are small, Gram-negative, nonmotile, nonspore-forming, rod-shaped (coccobacilli ...
Brucellosis caused by B. abortus best fits the characteristics of the plague described in Oedipus Rex. Although the disease progression of brucellosis in modern times may make it seem unlikely, it was at least one agent in what may have been a multicomponent plague, along with Salmonella enterica serovar Typhi or another pathogen, or possibly ...
He discovered Brucella abortus in 1897, which came to be known as Bang's bacillus. Bang's bacillus was the cause of the contagious Bang's disease (now known as Brucellosis) which can cause pregnant cattle to abort, and causes undulant fever in humans.

Direct contact with infected animal [33] Oral, by ingestion of unpasteurized milk or milk products [33] Brucellosis: mainly fever, muscular pain and night sweats. doxycycline [33] streptomycin or gentamicin [33] Campylobacter jejuni: Fecal–oral from animals (mammals and fowl) [33] [48]
Brucella suis is a bacterium that causes swine brucellosis, a zoonosis that affects pigs. The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis, and may even affect joints and other organs. [1] The most common symptom is abortion in pregnant susceptible sows at any stage of ...
Salmonella, a type of bacteria, is a leading cause of foodborne illness, hospitalizations and deaths in the U.S., according to the Centers for Disease Control and Prevention.
She proved that Bacillus abortus (called Brucella abortus) caused the disease brucellosis (undulant fever or Malta fever) in both cattle and humans, which led to the pasteurization of milk in the US in 1930. Evans was the first woman president elected by the Society of American Bacteriologists.
