PathogenThis section has been translated automatically.
- Brucella abortus (pathogen of M. Bang = Febris undulans bovina): The main host is the cattle (causes a feverish general infection there).
- Brucella melitensis (causative agent of Malta fever = Mediterranean fever, Febris mediterranea, Febris undulans melitensis, Bruce septicaemia, wave fever): Main hosts are sheep and goats.
- Brucella suis (porcine brucellosis suis): the main host is the pig.
Occurrence/EpidemiologyThis section has been translated automatically.
B. abortus: Occurs worldwide, especially in temperate and tropical areas where cattle breeding is practised.
Brucella melitensis: Mediterranean, Africa, South America.
B. suis: North America.
EtiopathogenesisThis section has been translated automatically.
Clinical featuresThis section has been translated automatically.
Incubation period 2-6 weeks. A prodromal stage with uncharacteristic general symptoms is followed by the stage of bacteremia with typical, but not obligatory, wave-like temperature spikes (undulating fever): fever slowly rising to 38-40 °C over 5-7 days, followed by an equally slow decline. These episodes can be repeated for weeks or months. In addition, hepatosplenomegaly, headaches, aching limbs and possibly gastrointestinal symptoms. The skin may show extremely varied, more or less generalized exanthema, macular, papular, psoriasiform, hemorrhagic, erythema exudativum multiforme.
In the subsequent stage of organ manifestation, formation of granulomas in lymph nodes, liver, bones and other organs. Rarely in the skin as uncharacteristic, ulcerating nodules, plate-like infiltrates, ecthymata-like efflorescences.

TherapyThis section has been translated automatically.
Therapy of choice: Doxycycline 200mg/day p.o. + Rifampicin 600-900mg/day p.o. over 6 weeks
Alternative: Combination of tetracycline (e.g. tetracycline Wolff) 2 g/day for 3-6 weeks and streptomycin (e.g. strepto-fatol) 1 g/day i.v. or i.m. for 2 weeks. For mild infections monotherapy with tetracyclines is sufficient.
Alternatively: Doxycycline 2 times/day 100 mg p.o. instead of tetracycline.
In children under 12 years of age: Trimethoprim/Sulfamethoxazol (e.g. Cotrimox-Wolff Saft 1/2-2 measuringsl. depending on age) for 4 weeks. Combination of this therapy with rifampicin (e.g. Eremfat) 10-15 mg/kg bw/day p.o. is recommended. Treatment with rifampicin alone is not recommended due to rapid development of resistance.
Progression/forecastThis section has been translated automatically.
With therapy in the acute phase (start of therapy during the first 3 months) the chances of recovery are 90-100%, later 60-80%.
If therapy is started late, it is often not possible to eliminate the pathogens completely; chronic, long lasting courses with recurrent flare-ups of the disease are possible. In approx. 5% of the treated cases, relapses due to persistent sensitive pathogens occur, so that a new therapy attempt with the existing regime may be possible (antibiogram!).
