Indirect haemagglutination tests on sera from 757 South American camelids (alpacas, llamas and vicunas) carried out in the Andean region of Peru, revealed evidence of exposure mainly to Mycoplasma mycoides subspecies mycoides LC. The incidence of detectable antibodies to this mycoplasma in 554 alpacas was 5.0 per cent and in 141 llamas 15.6 per cent. Antibody to Mycoplasma capricolum and the F38 biotype was detected in 0.9 per cent and 0.2 per cent of alpacas, respectively. In a group of 62 vicunas only one reactor to both M m mycoides LC and M capricolum was observed. No reactors to M mycoides subspecies capri or M agalactiae were observed in the flocks examined. Antibodies to mycoplasma were also detected in nine out of 10 goat flocks tested. The incidence of antibodies to M m mycoides LC was 13.8 per cent, 3.8 per cent for M capricolum and 1.8 per cent for the F38 biotype. In a group of 110 sheep, six reactors (5.5 per cent) to M m mycoides LC and one (0.9 per cent) to F38 were observed. The implications of these results are discussed in relation to the involvement of mycoplasmas in existing disease in camelids in Peru.
在秘鲁安第斯地区对757只南美骆驼科动物(羊驼、美洲驼和小羊驼)的血清进行的间接血凝试验显示,主要存在感染丝状支原体丝状亚种LC的证据。在554只羊驼中,可检测到针对这种支原体抗体的发生率为5.0%,在141只美洲驼中为15.6%。分别在0.9%和0.2%的羊驼中检测到了针对山羊支原体和F38生物型的抗体。在一组62只小羊驼中,仅观察到1只对丝状支原体丝状亚种LC和山羊支原体均呈反应阳性。在所检查的畜群中,未观察到对丝状支原体山羊亚种或无乳支原体呈反应阳性的动物。在检测的10个山羊群中,有9个也检测到了支原体抗体。针对丝状支原体丝状亚种LC的抗体发生率为13.8%,针对山羊支原体的为3.8%,针对F38生物型的为1.8%。在一组110只绵羊中,观察到6只(5.5%)对丝状支原体丝状亚种LC呈反应阳性,1只(0.9%)对F38呈反应阳性。本文结合支原体在秘鲁骆驼科动物现有疾病中的作用对这些结果的意义进行了讨论。
