猪附红细胞体人工感染小鼠的病理学试验

附红细胞体是寄生于人、猪以及其他动物的红细胞表面、血浆以及骨髓内的一群多形态微生物.猪附红细胞体病缺乏特征性临床症状和病理变化,使发病率和死亡率大大升高,给养殖户造成很大经济损失.本试验旨在研究猪附红细胞体病对小鼠血液生理指标的影响,及对小鼠各脏器的致病程度,为附红细胞体病的诊断及深入研究提供基础试验依据.     

猪败血性链球菌与附红细胞体混合感染病例

猪败血性链球菌病是猪链球菌感染引起的一种急性败血性传染病,猪附红细胞体病是由猪附红细胞体寄生于猪红细胞而引起的一种散在的热性、溶血性传染病.本文以某猪场这2种病混合感染病例为题材,从发病基本情况、临床症状、剖检变化、实验室检验、防治措施等6个方面对该混合感染病例做了详尽的阐述.

附红细胞体自然感染猪血液生化指标的检测

附红细胞体 ( Eperythrozoon)是寄生于人畜血液、红细胞及骨髓中的一群微生物。附红细胞体病( Eperythrozoonosis)简称附红体病 ,本病危害的严重性主要表现在感染畜种基本齐全 ,病原分布逐年扩大 ,临床病例逐步增多 ,从 1 92 8年至今的 70多年中 ,在世界范围内已有 30多个国家发生此病。由于该病在多数情况下呈潜伏状态 ,临床发病的不显现性 ,并没有引起人们的足够重视。近年来 ,随着附红细胞体病临床病例的增多 ,家畜附红细胞体感染的暴发流行 ,影响畜牧业发展 ,对人类健康造成威胁 ,才逐渐被国内外学者关注。本试验在前人研究的基础上 ,…     

Pathogenicity of Eperythrozoon suis alone and when mixed with Babesia trautmanni in experimentally-infected pigs

The pathogenicity of a single infection with Eperythrozoon suis and of a mixed infection of E. suis and Babesia trautmanni in experimentally-infected pigs, was described. In the pigs with a single infection, parasitaemia of E. suis was observed 4 days after blood inoculation. Although parasitaemia with this parasite was also observed on the 4th day in a mixed infection, the parasitaemia of B. trautmanni was not noted until 14 days after inoculation at a period when that of E. suis had started to fall. No parasitaemia was observed in any of the pigs in the splenectomized and unsplenectomized uninoculated control animals. The pigs carrying either single or mixed infections had pyrexia and their temperatures were consistently higher than those of the control animals. Infected pigs also showed anaemia with significant decline in Pcv, Hb and RBC values. The total WBC count rose in the infected pigs and the rise was more pronounced in pigs carrying E. suis alone. In addition, it was only in pigs infected by E. suis alone that a decline in the percentage of neutrophils and a rise in percentage lymphocytes was observed.     

Indirect hemagglutination for Eperythrozoon suis detection in experimentally and spontaneously infected swine

Ten splenectomized and non-splenectomized pigs were experimentally infected with E. suis bearing red blood cells in order to determine the antibody response. All animals were monitored for antibody titer by indirect hemagglutination over a period of 80-290 days postinfection. Latent E. suis infection only yielded a detectable antibody titer in one pig. Acutely infected pigs had a titer ranging up to 1:640. Maximum antibody response lasted only 2 months and dropped below the level of detection of our assay within 2 to 3 months. At this time, the clinical symptoms could reappear and antibodies were again detectable. However, no booster effect was observed with this second outbreak. We also determined the antibody frequency in 138 pigs from 16 herds in Southern Germany. Pigs from only 4 out of 6 clinically positive herds had antibody titer against E. suis. 20 out of 78 pigs of the clinical positive herds demonstrated a detectable E. suis antibody titer. In 10 herds that were asymptomatic and presumed uninfected all 80 pigs were serologically negative for E. suis.     

Exploratory study of Mycoplasma suis (Eperythrozoon suis) on four commercial pig farms in southern Brazil

Mycoplasma suis (Eperythrozoon suis) was detected by PCR and Southern blot in 186 pigs (121 sows, 61 piglets and four boars) on four farms in southern Brazil. DNA was extracted from blood samples and a 16S rRNA gene fragment of M suis was amplified by PCR; Southern blot analysis was then performed on all the samples. Twenty-two of the sows (18.2 per cent) were positive by PCR, and 40 (33.1 per cent) were positive by Southern blot; only one piglet and one boar were positive. The packed cell volume and total plasma protein of the pigs and their PCR and Southern blot results were not significantly different on the four farms, but higher proportions of the pigs were positive by Southern blot than by PCR (P<0.05). The packed cell volume and total plasma protein concentrations of the M suis positive and negative sows were not significantly different.
