【摘要】 2001年冬季,福建省大部分地区猪群出现无名出血高热疾病,其临床表现为仔猪高热稽留、极度呼吸困难及相当高的病死率;怀孕母猪发生一过性高热及流产率显著升高,应用抗菌素治疗效果差。对收集的22份典型病料进行病原分离和鉴定,结果从36％病料中观察并分离到链球菌,27％的病料中观察并分离到附红细胞体,而且混合感染比较严重,其中以伴发猪繁殖与呼吸综合征、猪瘟居多。共分离出6株猪繁殖与呼吸综合征病毒,2株衣原体,1株猪伪狂犬病毒,还分离到2株不明病原。说明该病的流行并非由单一病原引起,而是由多种病原混合感染的结果。更多还原

【Abstract】 In the winter of 2001, an epidemic so called "infectious respiratory syndrome" in swine herds occurred in the most areas of Fujian Province; Affected piglets showed continued fever, severe dyspnea and high morbidity rate; Infected pregrant sow displayed temporary fever, high abortion rate. Antibiotics treatment did not reach satisfactory effect. Twenty two clinical samples were collected and preliminary etiological diagnoses were made by means of bacteria dyeing, animal inoculating, antibody detection, virus isolation and reverse transcription-polymerase chain reaction. The results show that: (1) the swine infected streptococcus suis and Epery fhrozoon suis accounted for 36% and 27%, respectively. (2) Mixed infection was commonly happened in these diseased animal, in the most cases occurred with PRRSV (Porcine reproductive and respiratory syndrome virus) and classical swine fever virus; six of PRRSV strains, two chlamydiae, one pseudorabies virus, and two of unknown viral pathogens were isolated from these samples. It indicated that the syndrome is not caused by single pathogen but several interactive pathogens.更多还原
