利用细菌分离培养方法和PCR方法对天峻县快尔玛乡某养殖户中2只病死绵羊组织进行检测,经细菌分离培养未分离到可疑病原,用PCR方法检测2只病死绵羊肺脏及1号羊脾脏,均为绵羊肺炎支原体阳性。综合临床症状、常规检测以及PCR检测结果,诊断为羊群感染了绵羊肺炎支原体,从而导致了传染性胸膜肺炎。 相似文献

A microbiological study of the mycoplasma flora in the respiratory tracts of cattle and goats in selected regions of Tanzania is described. In the examination of cattle, mycoplasmas were isolated from 60 (17.8%) of the 338 examined lung samples, 8 (47.1%) of the 17 lymph nodes, 4 (13.3%) of the 30 pleural fluid samples and 4 (3.9%) of the 103 nasal swabs examined. All the isolates were identified as Mycoplasma mycoides subsp. mycoides, Small Colony type except for one isolate from pleural fluid which was identified as Mycoplasma arginini. M. mycoides subsp. mycoides, Small Colony type was isolated from samples originating from Dodoma, Iringa, Mbeya, Morogoro and Shinyanga regions where outbreaks of contagious bovine pleuropneumonia had been reported. In the examination of goats, mycoplasmas were isolated from 54 (34.0%) of the 159 examined lung samples, 41 (18.1%) of the 226 nasal swabs and 4 (40.0%) of the 10 pleural fluid samples. The species demonstrated were Mycoplasma capricolum subsp. capripneumoniae, M. mycoides subsp. mycoides, Small Colony type Mycoplasma ovipneumoniae and M. Capricolum subsp. arginini. The isolation of M. capripneumoniae in the Coast and Morogoro regions confirmed the presence of contagious caprine pleuropneumonia in the regions. 相似文献

Mycoplasmas isolated from the nasal cavity of sheep in a ram test station were examined to determine their identity and prevalence. Specimens were obtained for mycoplasmal culture in 1980, 1982, and 1983 from 558 sheep, and mycoplasmas were isolated from 630 specimens from 320 sheep (57.3%). The isolates were characterized and differentiated into groups on the basis of sensitivity to digitonin, fermentation of glucose, and hydrolysis of arginine. Isolates in some groups were further characterized by use of additional diagnostic media, and their identity was confirmed by agglutination or growth inhibition with antiserum prepared from reference mycoplasmas. Of the 320 sheep with mycoplasmas, 293 had Mycoplasma ovipneumoniae, 12 had M arginini, and 1 had M capricolum. Two sheep had Acholeplasma spp, and 3 sheep had unidentified Mycoplasma spp. The remaining 9 sheep had M ovipneumoniae in combination with Acholeplasma spp (n = 3), M arginini (n = 3), M capricolum (n = 2), and an unidentified Mycoplasma spp (n = 1). The biochemical reactions of the M ovipneumoniae from the 293 sheep were similar, but varied in the degree of growth and fermentation in the basal medium containing glucose. The high prevalence of M ovipneumoniae indicated that it may be commensal in the upper respiratory tract of healthy sheep. 相似文献

青海省互助某羊场藏系绵羊发生肺炎疾病,为了快速准确诊断藏羊肺炎发病的致病病原微生物,及时防控和治疗,采集病死绵羊肺样品,利用PCR分子生物学方法进行鉴定与生物信息学分析。经过分子鉴定,此羊场引发肺病的病原是绵羊肺炎支原体(Mycoplasma ovipneumoniae, MO);测序结果显示样品中鉴定的为同一株病原,鉴定的菌株的16S rRNA基因与参考序列EU265779的同源性达到99.86%。同时遗传进化树显示,鉴定的菌株与GenBank中的绵羊肺炎支原体聚成一大支,其关系最近,在进化角度证实此次鉴定的确实为绵羊肺炎支原体。结果表明,此羊场引发肺炎疾病的病原是绵羊肺炎支原体,提示要对羊群进行相关的病原学研究和流行病学调查,为针对性地对细菌性病原进行对症治疗提供参考。 相似文献

Mycoplasma ovipneumoniae NCTC 10151(T) and four new isolates from UK sheep flocks were compared. Only glucose and pyruvate were used as energy sources by the five strains: glucose was the best energy source for the type strain, pyruvate supported better growth of the new strains. Whole cell protein patterns and antigenic profiles showed high similarity between all five strains. The new isolates fell into two groups in ELISA tests. Serum samples from 30 pneumonic sheep were assessed for M. ovipneumoniae infection and Mycoplasma arginini co-infection. Fourteen (out of 30) serum samples were positive for M. ovipneumoniae both by ELISA and immunoblotting. Twelve antigenic proteins of M. ovipneumoniae were detected in infected serum samples: the antigen patterns were unique, with between one and at least seven occurring in any one sample. All serum samples were designated as negative for M. arginini antibodies by both ELISA and immunoblotting. 相似文献
