Abortus «2024»

In its primary host, cattle, B. abortus typically localizes in the reproductive tract. The hallmark clinical signs of infection include:

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

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

In humans, it can cause a debilitating, chronic illness characterized by undulant fever, joint pain, and fatigue.

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 In its primary host, cattle, B

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

Humans typically acquire B. abortus through direct contact with infected animals or the consumption of . This zoonotic disease is a critical global concern,

Efforts to manage B. abortus focus on surveillance, diagnostic testing, and vaccination.
