Study Notes
Brucellosis Ranking and Transmission
-
Brucellosis is a significant zoonotic disease, though its precise ranking among all zoonotic diseases varies depending on the metric used (incidence, mortality, etc.).
-
In cattle, brucellosis primarily spreads through contact with infected reproductive fluids (e.g., during mating or abortion).
-
Brucellosis in cattle does not commonly manifest as [missing information needed to complete this point. The question requires a list of options from which to determine which is not a symptom].
-
Humans primarily contract brucellosis through direct or indirect contact with infected animals or their products (e.g., unpasteurized dairy products, contact with infected tissues).
-
The persistence of Brucella in the environment is largely due to its resistance to environmental stressors, allowing it to survive for extended periods outside a host.
Brucellosis Clinical Signs and Diagnosis
-
In cows, the most common indicator of brucellosis is abortion or reproductive problems.
-
A primary diagnostic method for brucellosis involves serological tests (detecting antibodies in blood samples).
-
In infected bulls, reduced fertility or orchitis (inflammation of the testicles) is most frequently observed.
Brucellosis Treatment
-
The 'LA-OTC' treatment regimen involves long-acting antibiotics (specifics regarding the antibiotics are not provided).
-
Vaccination is a non-antibiotic intervention primarily aimed at preventing brucellosis infection.
