Chronic Brucellosis involves muscle aches, easy fatigability, fever and depression.

Human Brucellosis is acquired from ingesting infected milk or milk products from cattle milk and is caused by brucella abortus. Occasionally acquired via respirations and veterinarians can catch it through skin abrasions.
