The nose is not enough: Multi‐site sampling is best for MRSP detection in dogs and households
Abstract Background Following recovery from meticillin‐resistant Staphylococcus pseudintermedius (MRSP) infection of any type, dogs may continue to carry MRSP asymptomatically on skin and mucosae, contributing to the spread of this multidrug‐resistant, veterinary hospital‐associated pathogen with zoonotic potential to others and into the environment ...

通过不同清洗方法对膜通量恢复效果的评价以及对污染膜和各步清洗后对膜表面和断面形貌的观察,对膜生物反应器工艺中的膜污染特征和膜污染进行了研究。结果表明,清水冲洗能消除纤维膜之间淤积的污泥和膜表面松散的污染层,次氯酸钠可以清除膜表面的微生物和有机污染物,而硫酸和柠檬酸能清除膜上的无机物垢。在膜外表面的污染物主要为生物膜和凝胶层污染,而膜内表面的污染物主要为滋生的微生物和无机污染物。对应各步清洗后膜通量的恢复,可以推出,在试验的工艺条件下,无机物污染对膜过滤阻力的影响较大。在此基础上 ...
