False-colour transmission electron micrograph (TEM) of the bacteria Brucella abortus, the species causing brucellosis in cattle & humans. Individual bacterium are Gram-negative, spherical or rod-shaped. B. abortus is unable to establish itself in immature animals, but invades the udder & uterus in cows & the testis in bulls. Symptoms include sickness, loss of appetite & general weakness, leading to chronic fever & swelling of lymph nodes. Transmission to man occurs through direct contact with an infected animal (goats, pigs & sheep are also affected) or through drinking contaminated milk. Magnification: X 10,000 at 35mm size.
