Study Notes
- Brucellosis is a contagious disease affecting cattle, goats, pigs, and humans, characterized by endometritis and abortion in cattle.
- Three species of Brucella cause brucellosis: B. abortus in cattle, B. melitensis in goats, and B. suis in pigs. All are Gram-negative bacilli.
- Infection in cattle can occur by ingestion, coitus, and contact with infected materials.
- After infection, bacteraemia occurs and the organisms are disseminated throughout the body, localizing in various organs such as lymph nodes, spleen, uterus, mammary glands, liver, testicles, prostate, seminal vesicles, joints, and bone marrow.
- During pregnancy, infection localizes in the placenta, leading to fetal death and abortion due to necrosis and interference with fetal circulation.
- Gross lesions in brucellosis include a dull and granular appearance of maternal caruncles and fetal cotyledons in the placenta, edematous inter-cotyledonary areas filled with brown exudate, and an edematous, sero-fibrinous, or sanguinous fetus with bronchopneumonia, suppurative or hemorrhagic gastroenteritis, and hyperplasia of the lymph nodes.
