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

T herd replacement is same

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

T worldwide yes and boars

Swine brucellosis can be treated successfully with antibiotics

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

Chronic cases of brucellosis cause lameness in both boars and sows

Calves can be infected with brucellae during pregnancy if the cow is infected

The maintaining host of Bruecella abortus is the goat and the sheep

Calves can be born with Brucella

Brucellosis of cattle is mainly limited to the genital tract

In the case of bovine brucellosis abortion usually occurs after fifth month of gestation

The S19 strain is an inactivated B. melitensis strain, which can be used for brucellosis

ABR test cannot be used to test colostrum

Bovine brucellosis is a self-limiting disease

Bovine brucellosis was described for the first time by Sir David Bruce in 1886

In ABR (Abortus bang ring/Brucella milk ring) test, we detect brucella **antigens** in the milk

S19 vaccine is a live vaccine, which can cause abortion in pregnant cows

Cattle are generally infected with Brucella per os

Bovine brucellosis is widespread within the EU

Infected cattle can be recognized by detecting Brucella in blood with ELISA

**Antibodies** against Brucella abortus are detected in the ABR test

Male calves may be vaccinated with vaccines containing live attenuated strains, without any side effects

Calves shows clinical sign after weaning when infected young with brucellosis

Bovine brucellosis is seen in most European countries

If young calves are infected with brucellosis, the bacteria remain in the lymph nodes until maturity

Histophilus somni and Actinobacillus seminis can cause similar lesions in the genitals of rams as Brucella ovis

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

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

Infectious epididymitis is caused by B. ovis

You can get B. ovis free only with stock exchange

F-test and remove

Ewes are lifelong carriers of Brucella ovis

AGID can be used to diagnose brucellosis in sheep

B. melitensis can disappear spontaneously from sheep and goat

Herd replacement is the only method of eradication of B. melitensis in a goat herd

Brucella melitensis is an obligate pathogenic bacterium in sheep and goat

Brucella melitensis is sporadic in Hungary

Sheep and goats can be infected per os with Brucella melitensis

Self-limiting nature of brucellosis caused by Brucella melitensis is strong

Antibodies against Brucella melitensis can be detected in small ruminants all over Europe

B. melitensis brucellosis is strongly self-limiting

Goats and sheep are primary hosts of B. melitensis

Brucella suis can infect dogs

Dogs and cats can be infected with brucella abortus without any clinical signs

Brucella abortus can infect dogs

Brucella canis can infect humans

Hemoculture is a good diagnostic tool in the diagnostic work of canine brucellosis

Abortion due to canine brucellosis occurs in final phase of pregnancy

Canine brucellosis differs from other brucella infections since it’s a long-term active infection

Canine brucellosis can cause iridocyclitis

Abortion usually occurs in the late phase of pregnancy in case of canine brucellosis

Epididymitis and orchitis are typical clinical signs of canine brucellosis

Attenuated vaccines are widely used for the prevention of canine brucellosis

Strong self-limitation can be seen in the case of canine brucellosis

In case of brucellosis, horses suffer from bursitis and they can rupture

In case of brucellosis hares can maintain their own infectious cycle, and do not need to be infected by cattle

Reindeers are important in maintaining and infecting swine herds with B. suis
