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

Brucella suis can cause severe abortion in cattle
F
Farmed pigs are regularly vaccinated against brucellosis in Europe in order to prevent infection from wild boars
F
vaccination only allowed with rev 1 for brucella melitensis in sheep and goats
Stock exchange is the only safe eradication method in case of swine brucellosis

herd replacement is same
B. suis biotype 2 is widespread in wild swine population all over the world

worldwide yes and boars
Swine brucellosis can be treated successfully with antibiotics
F
Brucella suis was isolated by Sir David Bruce as a first time in 1886 in Malta Island
F
pou ton malaka ton diko mas to suis
Maintaining host of swine brucellosis are reindeer, hare and small rodents
F
wild boars
Brucellosis in swine causes abortion at any time of the pregnancy
T
Chronic cases of brucellosis cause lameness in both boars and sows
T
Calves can be infected with brucellae during pregnancy if the cow is infected
F
The maintaining host of Bruecella abortus is the goat and the sheep
F
Calves can be born with Brucella
F
Brucellosis of cattle is mainly limited to the genital tract
F
In the case of bovine brucellosis abortion usually occurs after fifth month of gestation
T
The S19 strain is an inactivated B. melitensis strain, which can be used for brucellosis
F
ABR test cannot be used to test colostrum
T
Bovine brucellosis is a self-limiting disease
T
Bovine brucellosis was described for the first time by Sir David Bruce in 1886
F
In ABR (Abortus bang ring/Brucella milk ring) test, we detect brucella antigens in the milk
T
S19 vaccine is a live vaccine, which can cause abortion in pregnant cows
T
Cattle are generally infected with Brucella per os
T
Bovine brucellosis is widespread within the EU
F
Infected cattle can be recognized by detecting Brucella in blood with ELISA
T
Antibodies against Brucella abortus are detected in the ABR test
T
Male calves may be vaccinated with vaccines containing live attenuated strains, without any side effects
F
Calves shows clinical sign after weaning when infected young with brucellosis
F
Bovine brucellosis is seen in most European countries
F
If young calves are infected with brucellosis, the bacteria remain in the lymph nodes until maturity
T
Histophilus somni and Actinobacillus seminis can cause similar lesions in the genitals of rams as Brucella ovis
T
Brucella ovis mainly causes abortion, clinical signs in males are rare
F-the other way
Agar gel diffusion test and ELISA are used for the detection of infection with Brucella ovis
T
Brucella ovis can cause ascending infection of the genital tract
T-in rams
Sometimes abortion can be seen in the case of brucellosis of sheep caused by B. ovis
T
Infectious epididymitis is caused by B. ovis
T
You can get B. ovis free only with stock exchange
F-test and remove
Ewes are lifelong carriers of Brucella ovis
F
AGID can be used to diagnose brucellosis in sheep
T
B. melitensis can disappear spontaneously from sheep and goat
T
Herd replacement is the only method of eradication of B. melitensis in a goat herd
F
Brucella melitensis is an obligate pathogenic bacterium in sheep and goat
T
Brucella melitensis is sporadic in Hungary
F
Sheep and goats can be infected per os with Brucella melitensis
T
Self-limiting nature of brucellosis caused by Brucella melitensis is strong
T
Antibodies against Brucella melitensis can be detected in small ruminants all over Europe
F
B. melitensis brucellosis is strongly self-limiting
T
Goats and sheep are primary hosts of B. melitensis
T
Brucella suis can infect dogs
T
Dogs and cats can be infected with brucella abortus without any clinical signs
T
Brucella abortus can infect dogs
T
Brucella canis can infect humans
T
Hemoculture is a good diagnostic tool in the diagnostic work of canine brucellosis
T
Abortion due to canine brucellosis occurs in final phase of pregnancy
T
Canine brucellosis differs from other brucella infections since it’s a long-term active infection
T
Canine brucellosis can cause iridocyclitis
T
Abortion usually occurs in the late phase of pregnancy in case of canine brucellosis
T
Epididymitis and orchitis are typical clinical signs of canine brucellosis
T
Attenuated vaccines are widely used for the prevention of canine brucellosis
F
Strong self-limitation can be seen in the case of canine brucellosis
F
In case of brucellosis, horses suffer from bursitis and they can rupture
T
In case of brucellosis hares can maintain their own infectious cycle, and do not need to be infected by cattle
T
Reindeers are important in maintaining and infecting swine herds with B. suis
