Scientific name
Brucella abortus, Brucella melitensis, Brucella canis, Brucella ovis, Brucella neotomae, Brucella microti
Strain of Brucella that typically affects humans is ________ but B. suis, B. abortus, and B. canis all have zoonotic ability
Brucella melitensis
Seen with severe cases
CNS and lining of heart affected
Eradication program in the U.S.
Cooperative State Federal Brucellosis Eradication Program
Licensed vaccine used in nonpregnant female cattle 4-12 months of age

Brucella is usually spread through contact with infected
birthing tissues and fluids
Brucellosis is a bacterial disease caused by various Brucella species, which mainly infect
cattle, swine, goats, sheep, and dogs
Species involved
cattle, swine, goats, sheep, dogs, deer, elk, humans
Disease is transmitted from animals to humans by
consuming unpasteurized milk and dairy, consuming undercooked meat, or skin penetration
Brucellosis is considered one of the most serious disease of livestock due to
damage done by the infection
Major damage
decreased milk production, weight loss, loss of young, infertility, and lameness
Arrange ______ for exposed and potentially infected animals
diagnostic workups, necropsies, or both
Common flu-like symptoms seen
fever, sweats, headaches, back pain, physical weakness
_____- like symptoms
flu-like symptoms
Humans generally acquire the disease through direct contact with
infected animals, eating or drinking contaminated animal products, or inhaling airborne agents
bacteria can be found in
milk, blood, urine, semen
Aborted cattle fetuses show
necrosis of cotyledons
most common complication/morbidity
osteoarticular involvment
Antemortem skin lesions are
papulonodular and maculopapular eruptions with erythema nodosum-like lesions
PCR is very reliable at determining Brucella in ______ but it's expensive so less common
peripheral blood and tissues
Apparent lowering of fertility with
poor conception rates, retained afterbirths with resulting uterine infections, and (occasionally) enlarged, arthritic joints
Management
proper sanitation, PPE, and herd management
Brucellosis also known as
remitting fever, undulant fever, Mediterranean fever, Maltese fever, Gibraltar fever, Crimean fever, goat fever, Bang disease
It can affect many different organs including
repro system, liver, heart, CNS
Detection of Brucella species by culture can sometimes be unsuccessful so ______ is preferred
serological testing
Serious disease due to rapidity of ______ and it being ______
spread, zoonotic
The primary human serological test used in lab settings is the
standard agglutination test
True or False: recommended to not use a singular antibiotic to treat but instead a combo or staggering
true
Geographic location
worldwide but mostly eradicated in U.S.
