The presence of infection with Mycoplasma species in association with lung consolidation, environmental temperature and relative humidity was investigated in 410 clinically healthy fattening lambs from five different feedlots in Extremadura (southwestern Spain). Isolates of Mycoplasma species were obtained (n= 117), including Mycoplasma ovipneumoniae (n = 18) and Mycoplasma arginini (n = 99). Two seasonal periods were identified. The first period, which included February, March, September, October, and November, had an average temperature of 17.5 ± 4.7 °C and a relative humidity of 61.3 ± 15.8%. The second seasonal period, which included the months from April to August, had an average temperature of 22.9 ± 5.5 °C and a relative humidity of 48.4 ± 10.7%. Most Mycoplasma species were isolated from the second seasonal period, indicating that higher temperatures and lower relative humidity favour the presence of Mycoplasma species. M. arginini was also associated with lung consolidation.
在西班牙西南部埃斯特雷马杜拉的五个不同饲养场的410只临床健康的育肥羔羊中，研究了支原体感染与肺实变、环境温度和相对湿度之间的关系。获得了支原体分离株（n = 117），包括绵羊肺炎支原体（n = 18）和精氨酸支原体（n = 99）。确定了两个季节期。第一个季节期包括2月、3月、9月、10月和11月，平均温度为17.5±4.7°C，相对湿度为61.3±15.8%。第二个季节期包括4月至8月，平均温度为22.9±5.5°C，相对湿度为48.4±10.7%。大多数支原体分离株是在第二个季节期分离到的，这表明较高的温度和较低的相对湿度有利于支原体的存在。精氨酸支原体也与肺实变有关。
