Novel sequence types and low levels of antimicrobial resistance associated with clinical mastitis in sheep flocks across Scotland.

This research paper aimed to demonstrate that mammary secretions provided by sheep farmers across Scotland from cases of clinical mastitis are free from environmental contamination, as well as to provide information on the major bacterial causes of disease and levels of antimicrobial resistance. Mastitis represents one of most significant diseases of small ruminant production worldwide. and coagulase-negative Staphylococcal species are common pathogens isolated from cases of sheep mastitis.

Understanding the release, migration, and risk of heavy metals in coal gangue: An approach by combining experimental and computational investigations.

The lack of understanding on the environmental fate and implications of heavy metals in coal gangue (CG) has restrained its utilization. Conventional extraction methods provide empirical measures of heavy metal speciation, lacking a detailed description of bound strength, which limits long-term risk assessment. In this study, the releasing and migrating behavior of six heavy metals (Cd, As, Pb, Ni, Cu, and Cr) were investigated through an approach by combining experimental and computational investigations.
