Brucella melitensis is the most pathogenic; B abortus is associated with less frequent infection and a greater proportion of subclinical cases. The virulence of B suis strains for humans varies but is generally intermediate.Moreover, what is the natural source of Brucella spp?
Brucella spp. are the cause of brucellosis, which is a zoonosis transmitted by ingesting contaminated food (such as unpasteurized milk products), direct contact with an infected animal, or inhalation of aerosols.

They are nonmotile, nonencapsulated, and nonsporing; they grow aerobically or microaerophilically but do not grow anaerobically. Brucella abortus, Brucella suis, Brucella melitensis, Brucella ovis, Brucella canis, and Brucella neotomae are the species of Brucella and their natural reservoirs.How does Brucella reproduce?
In animals, Brucella are usually spread through contact with infected birthing tissues and fluids (e.g., placenta, aborted fetuses, fetal fluids, vaginal discharges). The bacteria can also be found in the milk, blood, urine and semen of infected animals.Can brucellosis cause infertility in humans?

While uncommon, transmission may also occur via tissue transplantation or blood transfusions.Is brucellosis an STD?
Canine brucellosis is a contagious bacterial infection caused by the bacterium, Brucella canis (B. canis). Infected dogs usually develop an infection of the reproductive system, or a sexually transmitted disease. Different species of Brucella infect sheep, goats, cattle, deer, elk, pigs, and other animals.Why is it called Q fever?
…an infectious disease caused by bacteria called Coxiella burnetii that affects both humans and animals.

Brucellosis is an infectious disease caused by bacteria from the genus Brucella. In the United States, brucellosis is much less common, with only 100-200 human cases reported each year. This decrease in cases in the United States is felt to be due to effective animal vaccination programs and milk pasteurization.
