摘要
[ Objective] This paper aimed to sum up the clinical symptoms, pathological changes, diagnosis and control method of swine streptococ- cicosis. [Method] III and dead pigs were dissected and organs such as liver, kidney, spleen and lung were aseptically took to inoculate in sheep blood agar, respectively, with bacteria isolated and purified to Gram staining and microscopy. [ Result] It was positive in Gram staining and hemoly- sis ting was formed on the sheep blood agar; the bacteria could ferment sucrose, sorbital, glucose, mannose, lactose and hydrolyze sodium hippu- rate. [ Conclusion] Through drug sensitive test, it indicated that swine streptococcus suis was highly sensitive to cephalosporin, ciprofloxacin and penicillin, and showed resistance to kanamycin, oxytetracycline, streptomycin and gentamicin.
