Abstract: In order to explore the histopathological characteristics of Salmonella infection in female rabbits, 6 dead female rabbits with depressed, shortness of breath and aborted from a large-scale rabbit farm in Henan province were examined. Endometrial bleeding, stillbirth, and hyperemia and congestion on the surface of heart, liver, spleen, lung and kidney were found by anatomical examination. The isolated pathogen was identified as Salmonella by isolation culture, morphological observation, serological typing, PCR identification, sequencing analysis and pathogenicity test. It was found that the myocardial fibers were bent or arranged disordered, liver cell granular degeneration or steatosis, lung extensive congestion, suppurative hysteritis, endometritis and other organs hyperemia by histopathological observation. The results of drug sensitivity test showed that the pathogens were sensitive to chloramphenicol, cephalosporins, penicillins, quinolones, tetracyclic, polypeptide, β-lactam and sulfa antibiotics, and had certain resistance to aminoglycoside (butamicana). In this study, Salmonella was successfully isolated from rabbits, the histopathological and drug sensitivity analysis of the infected female rabbits were carried out, which provides a basis for better prevention and control of rabbit salmonellosis.
