The bacteria are often spread through contact with aborted fetuses, placentas, or vaginal discharges. In the United States, wildlife reservoirs like bison and elk in the Yellowstone area maintain the pathogen, occasionally transmitting it back to livestock. Zoonotic Transmission and Human Health

Brucella abortus is a Gram-negative, facultative intracellular bacterium that primarily targets cattle and serves as a major etiological agent of . This zoonotic disease is a critical global concern, causing significant economic losses in the livestock industry and posing a persistent public health threat to humans. While some countries have successfully eradicated the pathogen, it remains endemic in regions including Latin America, the Middle East, Africa, and parts of Asia. Impact on Livestock

Informative Paper: Brucella abortus and Its Global Impact Introduction abortus

Infected animals frequently experience decreased fertility and retained placentas.

In its primary host, cattle, B. abortus typically localizes in the reproductive tract. The hallmark clinical signs of infection include: The bacteria are often spread through contact with

Contagious abortion, often occurring in the last trimester of pregnancy, is the most common sign.

Even with treatment, relapse occurs in 5–15% of cases due to the presence of "persister" cells that remain metabolically active within protective intracellular niches. Current Control and Prevention Strategies This zoonotic disease is a critical global concern,

Reduced milk production and the birth of weak calves further compound agricultural losses.
