Further, the LCHNPs show much better antibacterial potency against both gram-positive e.g., Staphylococcus aureus (S. aureus) and gram-negative e.g., Pseudomonas putida (P. putida) bacteria even in dark especially, with the lowest ever reported MIC value (e.g., 1 μg ml−1) against the P. putida bacterial strain and exhibit ROS mediated antibacterial proficiency.
Usually, they are characterized by high specificity to only Staphylococcus aureus cell wall components; however, some of them are also able to lyse cells of other staphylococci, e.g., Staphylococcus epidermidis-human pathogen of growing importance and also other groups of bacteria.
-- An increase in global resistance rates in many bacterial species responsible for both community- and healthcare-related infections, e.g., staphylococci, enterococci, gonococci, and enterobacteria (including E. coli, Salmonella spp and Shigella spp), Pseudomonas spp, Acinetobacter spp, and Mycobacterium tuberculosis) [ 1, 5- 7].
Hospital infections with multiresistant bacteria, e.g., Methicillin-resistant Staphylococcus aureus (MRSA), cause heavy financial burden worldwide.
Another difficulty encountered when studying CM risk factors is that risk factors for one mastitis etiologic agent, e.g. Staphylococcus aureus mastitis, may be different from the risk factors for mastitis caused by other etiologies, e.g., coliform mastitis.
Compounds 7a and 7c presented the most potent inhibitory activities against Gram-positive bacteria (e.g., Staphylococcus aureus 4220), Gram-negative bacteria (e.g., Escherichia coli 1924), and the fungus Candida albicans 7535, with MICs of 2.1 or 4.1 μmol/L.
Furthermore, antibody fragments and other 'affinity proteins' with capacity to specifically bind a certain protein, e.g. Staphylococcus aureus protein A-based affibodies, have been surface-displayed on staphylococci as initial efforts to create whole-cell diagnostic devices.
