肉犊牛沙门氏菌肺炎的诊治

Diagnosis and Treatment of Salmonella Pneumonia in Calves

为找出重庆丰都县和四川自贡市肉牛场肉犊牛肺炎的病原,从肉犊牛的鼻分泌物和肺组织共分离到29株细菌,经形态特性及生化试验,结合临床症状及病理变化,鉴定为沙门氏菌.用临床上常用的21种抗菌素纸片对分离菌进行药敏试验,结果显示所分离的沙门氏菌对头孢曲松等大部分头孢类药物、氨曲南和亚胺培南敏感性极高.临床上采用头孢曲松及壮观霉素进行治疗,效果良好.

Twenty‐nine strains of bacteria were isolated from the nasal secretions and lung tissues collected by the cattle farms of Fengdu of Chongqing and Zigong of Sichuan .They were identified as Salmonella through morphological observation and biochemical tests and based on clinical signs and pathological chan‐ges .Antibiotic sensitivity tests were made of the strains with 21 kinds of antibiotic disks which are .com‐monly used in the clinics .The isolated Salmonella strains were shown to be highly sensitive to the cepha‐losporin drugs such as ceftriaxone ,aztreonam and imipenem .Satisfactory effects were obtained when ceph‐alosporin and spectinomycin were used clinically to treat sick calves .
