Although the pathogenicity of Pasteurella multocida for psittacines (parrots and their relatives) has been documented in several case reports, the associated pathologic syndromes have not been well defined nor have the isolates been characterized. In addition, the prevalence of P. multocida in psittacines has not been determined. Three hundred twenty-eight psittacines (253 clinically healthy and 75 clinically ill) were cultured for P. multocida. Pasteurella multocida was not isolated from the pharynx, choana, or cloaca of psittacines. However, in five dead psittacines submitted for necropsy, P. multocida was isolated. These isolates were characterized, and all belonged to either somatic serotype 3 or 4,7. Pasteurella multocida somatic serotype 3 was isolated from psittacines with septicemia, whereas P. multocida somatic serotype 4,7 was isolated from psittacines with cutaneous lesions. The majority (four out of five) of the P. multocida isolates belonged to the subspecies multocida, and all isolates were susceptible to penicillin G, sulfisoxazole, gentamicin, erythromycin, tetracycline, and trimethoprim-sulfamethoxazole but resistant to streptomycin. DNA fingerprints demonstrated that isolates belonging to the same somatic serotype were genetically related. The isolate from a cockatiel that had been caught by a cat belonged to somatic serotype 3 and was not genetically related to the other two isolates belonging to this somatic serotype.
尽管多杀性巴氏杆菌对鹦鹉类（鹦鹉及其近亲）的致病性已在多篇病例报告中有记载，但相关的病理综合征尚未得到明确界定，分离株也未被鉴定。此外，鹦鹉类中多杀性巴氏杆菌的流行情况尚未确定。对328只鹦鹉（253只临床健康，75只临床患病）进行了多杀性巴氏杆菌培养。未从鹦鹉的咽、后鼻孔或泄殖腔中分离出多杀性巴氏杆菌。然而，在送交尸检的5只死亡鹦鹉中，分离出了多杀性巴氏杆菌。对这些分离株进行了鉴定，所有分离株均属于体细胞血清型3或4,7。从患有败血症的鹦鹉中分离出了体细胞血清型3的多杀性巴氏杆菌，而从患有皮肤病变的鹦鹉中分离出了体细胞血清型4,7的多杀性巴氏杆菌。大多数（5株中的4株）多杀性巴氏杆菌分离株属于多杀亚种，所有分离株对青霉素G、磺胺异恶唑、庆大霉素、红霉素、四环素和甲氧苄啶-磺胺甲恶唑敏感，但对链霉素耐药。DNA指纹图谱显示，属于相同体细胞血清型的分离株在基因上相关。一只被猫捕获的鸡尾鹦鹉的分离株属于体细胞血清型3，与属于该体细胞血清型的其他两个分离株在基因上不相关。
