The present invention relates to several methods to detect gram positive mastitis pathogens in a small sample of bovine milk by luminescence using a combination of specific reagents giving a “cow side” “in-stall” indication of the presence or absence of gram positive mastitis pathogens within a short period of time.

The present invention provides methods, assays, compositions, formulations, and constructs, particularly lytic peptide constructs, which relate to and are based on the activity and use of blood components, particularly serum albumin and lysozyme, and their activity and use to enhance or synergize with the bacterial killing effect of anti-bacterial lytic proteins and peptides.

In the present invention, the influence by flora of the skin on dermatitis is examined by analyzing Tmem79-knockout model mice, and a bacterium having a suppressive effect on dermatitis is identified, and the present invention relates to a pharmaceutical composition derived from such a bacterium, containing as active components one or more substances selected from: (a) a bacterial cell of an ampicillin-sensitive bacterium, or a constituent component of the bacterium; (b) a culture supernatant of an ampicillin-sensitive bacterium, or a purified product from the culture supernatant; (c) an extract of an ampicillin-sensitive bacterium; and (d) a metabolite of an ampicillin-sensitive bacterium.

A method for distinguishing among a first group of microorganisms belonging to a first taxon of Gram negative bacteria, the first group of bacteria exhibiting a mechanism of resistance to a treatment; a second group of microorganisms belonging to a second taxon of Gram negative bacteria, the second taxon of bacteria being different than said first taxon, and exhibiting a mechanism of resistance to a treatment identical to the mechanism of the first group; and a third group of Gram negative bacteria that is not resistant to the treatment.

Various embodiments disclosed herein provide for reagents and methods for rapidly isolating viable microbial cells, including S. pneumoniae, from positive blood culture samples. The resulting microbial pellet can be used for both identification and growth-based methods such as antimicrobial susceptibility testing. The buffers described herein may contain a base solution, non-ionic detergents, thiols, and optionally, ammonium chloride. The disclosed methods provide a process for rapidly isolating and concentrating viable microorganism(s) from PBC samples using only one sample preparation tube and centrifugation while removing cellular debris from the mammalian blood cells that may interfere with identification methods.

Provided is a diagnostic kit for determining infection with Methicillin-Resistant Staphylococcus aureus (MRSA) in a specimen, and a method for determining the infection with MRSA using the diagnostic kit is performed by visually observing a color change after LAMP reaction, and the color change is caused by a change in a magnesium concentration and confirmed using a specific dye compound which sensitively reacts with magnesium ions. The amplification of the MRSA DNA is performed using the loop-mediated isothermal amplification (LAMP), so that the diagnostic kit has advantages of being conveniently used anytime and anywhere and quickly diagnosing.
