Brucella Flashcards
Brucella species cannot tolerate high temperature (60 °C) and low pH (pH: 4).
T
Rose-Bengal test is used for the detection of antibodies against brucellae
T
Brucellae can be detected by staining in the placenta of aborted foetuses in the case of
brucellosis
T
Humans can acquire brucellosis from raw milk

F
Undulant fever, malaise, inappetence, fatigue, and muscle and joint pains can be the clinical
sings of human brucellosis
T
Brucella species are generally zoonotic agents
T
Brucella are facultative IC agents
T
Brucella is generally a notifiable disease
T
Among Brucella species Brucella melitensis is the most pathogenic species for humans
T
More than one serological test must be carried out from one serum sample at the same time
in the case of serodiagnostics of brucellosis
T
Brucellosis is generally a notifiable disease
T
Brucellosis is a chronic disease
T
Brucella species are gram-negative, fastidious, coccoid rod-shaped bacteria
T
There is a serological relationship among some brucella species, because of the same
polysaccharides in the cell wall
T
Worldwide distribution is characteristic for brucellosis
T
Köster staining is used for staining of brucellae
T
Brucella can be both acute or chronic in humans
T
Brucella melitensis is endemic in Mediterranean area
T
Brucella species are widely distributed all over the world
T
Brucella species are serologically uniform
F
Brucella species need cysteine or cystine as an additive for the culture
F
Brucella species are not zoonotic agents
F
Susceptibility of humans to different Brucella species is different
T
Consumption of raw milk is an important route of human Brucella infection
T
Brucella need chocolate agar to culture
F
There is a close antigenic relationship between B. ovis and B. melitensis
F
B. suis is a zoonotic agent
T
Brucella ovis needs CO2 to culture
T
Brucella are Gram-positive and Kster-positive bacteria
F
The antigens of Brucella are uniform
F
The majority of the Brucella species can infect humans
T
Brucella are not fastidious bacteria, they can be cultured on simple nutrient agar
F
Brucella species are non-motile, Gram-negative, small coccoid rods
T
There is a serological relationship among B. abortus, B. melitensis and B. ovis, because of the
same surface polysaccharides
F
There are no brucellosis-free countries in the world
F
Most of the Brucella species are zoonotic agents
T
There is close antigenic relationship between Brucella bovis and Brucella ovis
F
Brucella suis is a zoonotic agent
T
Brucella canis is stained red as a result of Kster-staining
F
Brucella species are not fastidious bacteria, we can use nutrient agar in diagnostic work
F
There is a strong relationship in antigenic structure of Brucella canis and Brucella ovis
T
Fetus, fetal membrane and blood sample from the dam must be send to the diagnostic
institute in abortion case
T
Human brucellosis was described for the first time by David Bruce in Malta Island in 1886
T
Brucella abortus stains red as a result of Köster-staining
T
There is a strong relationship in the antigenic structure of B. melitensis and B. suis
T
All of the Brucella species are zoonotic agents
F
Vaccination is a regularly used prevention method in the brucellosis free countries of EU
F
In the case of a same serum sample it is advisable to carry out more serological tests for the
detection of antibodies against Brucella species, because different serological tests can show
different results
T
Rev I. is an inactivated vaccine strain
F
There are no differences in serological features of Brucella species with veterinary
importance
F
Brucella are facultative intracellular bacteria
T
With Köster-staining all Brucella are positive
F
Sheep and goat are the reservoirs for Brucella
F
Hungary is Brucella free
F
Humans are resistant to Brucella melitensis
F
Raw milk consumption can be the source of human brucellosis
T
Vaccination against brucellosis is common in the EU
T
False?
Attenuated vaccine strains can cause abortion in pregnant animals
T
Focal necrosis and inflammation are seen in fetuses aborted due to Brucella
T
Brucella is an obligate pathogen
T
F? Facultative IC pathogen?
Brucella are a notifiable disease
T
Brucella can be found on the mucous membranes of the genital tract
T
All Brucella can be stained with Köster staining
F
There will be cross-reactions between S-type colonies in case of Brucella
T
Brucellosis is found in most parts of the world.
T
In sexually immature animals, Brucella multiplies in the lymph nodes
T
Brucellosis is usually introduced by infected asymptomatic animals.
T
Abortion caused by brucellosis is followed by retained fetal membranes
T
An attenuated vaccine is used in Hungary for prevention of B. melitensis
F
Brucella has average resistance
T
Brucella is seen only in the northern hemisphere
F
