Chapter2:CurrentTreatmentApproaches

2.1Antibiotics

Theprimarytreatmentforcaninebrucellosisisantibiotictherapy.Variousantibiotics,includingtetracyclines,fluoroquinolones,aminoglycosides,andtrimethoprim-sulfamethoxazole,haveshownefficacyagainstBrucellacanis.Combinationtherapywithmultipleantibioticsisoftenrecommendedtoenhancetreatmentsuccessandreducetheriskofresistancedevelopment.However,treatmentdurationistypicallyprolonged,rangingfrom4to6weeks,duetotheintracellularnatureofthebacteriumandthepersistenceofinfectioninreproductivetissues.

2.2SurgicalIntervention
