In countries with professional pig husbandry in stables, the prevalence of livestock-associated (LA) methicillin-resistant (MRSA) on farms has remained high or has further increased in recent years. Simple measures to reduce LA-MRSA among pigs have not yet been successfully implemented. The aim of this pilot study is twofold: first, to examine how the LA-MRSA status of LA-MRSA positive fattening pigs at the date of housing changes over the fatting period on straw bedding and, second, whether this change could be influenced by the quality of cleaning and disinfection (C&D). For this purpose, 122 animals are individually tested for LA-MRSA carriage at five sequential time points comparing pigs housed on a farm using straw bedding plus C&D ( = 59) vs. straw bedding plus simple cleaning ( = 63). At the time of housing, all animals in both groups are LA-MRSA positive. This status changes to 0% in the group with simple cleaning until the end of fattening and 28% in the C&D group. LA-MRSA in environmental and air samples is also reduced over the fattening period. The results indicate that keeping pigs on straw might be one way to reduce LA-MRSA during the fattening period with simple cleaning appearing to be more beneficial than C&D. Further investigations are necessary to determine the influencing factors more precisely.
在有专业猪舍养殖的国家，近年来农场中与家畜相关的（LA）耐甲氧西林金黄色葡萄球菌（MRSA）的流行率一直居高不下或进一步上升。尚未成功实施降低猪群中LA-MRSA的简单措施。这项试点研究的目的有两个：第一，研究在育肥期内，采用稻草垫料饲养时，LA-MRSA阳性育肥猪在入栏时的LA-MRSA状态如何变化；第二，这种变化是否会受到清洁和消毒（C&D）质量的影响。为此，在五个连续时间点对122头动物进行LA-MRSA携带情况的个体检测，比较采用稻草垫料加C&D的农场饲养的猪（n = 59）和采用稻草垫料加简单清洁的猪（n = 63）。入栏时，两组所有动物的LA-MRSA均为阳性。在简单清洁组，直到育肥结束时该状态变为0%，而在C&D组为28%。在育肥期内，环境和空气样本中的LA-MRSA也有所减少。结果表明，在育肥期采用稻草饲养猪可能是减少LA-MRSA的一种方法，简单清洁似乎比C&D更有益。需要进一步调查以更精确地确定影响因素。
