Summary of "'Biofilm Clippers'- enzyme formulation for bovine mastitic biofilm therapy."

Mastitis is one of the most important diseases that are threatening modern dairy farms. Biofilms of mastitic teat canal have serious clinical implications because of colonized pathogens having the ability to construct an extracellular polymeric substance (EPS) with increased tolerance to antimicrobials leads to difficulty in eradicating the infection. In this study, we investigated the synergistic biofilm disruptive effect of a combination of carbohydrate hydrolases targeting extracellular polysaccharides of biofilm matrix and we termed it as 'Biofilm Clippers (BC)'. Our findings demonstrate that the BC formulation exhibits intense biofilm-disrupting activity against Staphylococcus aureus biofilms. The results of the study showed that BC enables activity equivalent to physiologically achievable concentrations in disrupting biofilms of S. aureus in vitro. The synergistic anti-biofilm activities of BC on S. aureus biofilms demonstrated that the biofilm matrix is predominant of complex polysaccharides. Further, the confocal microscopic analysis demonstrates that the BC formulation is highly effective compared to the single treatment of either of the enzymes in disrupting the biofilm. To the best of our knowledge, this is the first report on the synergistic anti-biofilm activity of a class of enzyme formulation against mastitic biofilm mass. Even though a small study showed a promising effect on mastitic teat canal, further extensive investigation on a large number of bovines for mastitis therapeutic potential of this BC-derived product is now warranted.

Medical and Biotech [MESH] Definitions

A COAGULASE-negative species of STAPHYLOCOCCUS found on the skin and MUCOUS MEMBRANE of warm-blooded animals. Similar to STAPHYLOCOCCUS EPIDERMIDIS and STAPHYLOCOCCUS HAEMOLYTICUS, it is a nosocomial pathogen in NICU settings. Subspecies include generally antibiotic susceptible and BIOFILM negative capitis and antibiotic resistant and biofilm positive urealyticus isolates.

High molecular weight mucoproteins that form a protective biofilm on the surface of EPITHELIAL CELLS where they provide a barrier to particulate matter and microorganisms. Membrane-anchored mucins may have additional roles concerned with protein interactions at the cell surface.

The type species of DELTARETROVIRUS that causes a form of bovine lymphosarcoma (ENZOOTIC BOVINE LEUKOSIS) or persistent lymphocytosis.

The type species of LENTIVIRUS, subgenus bovine lentiviruses (LENTIVIRUSES, BOVINE), found in cattle and causing lymphadenopathy, LYMPHOCYTOSIS, central nervous system lesions, progressive weakness, and emaciation. It has immunological cross-reactivity with other lentiviruses including HIV.

A species of PESTIVIRUS causing systemic infections including BOVINE VIRUS DIARRHEA-MUCOSAL DISEASE and BOVINE HEMORRHAGIC SYNDROME in cattle and some other cloven-hoofed animals. There are several strains and two biotypes: cytopathic (rare) and non-cytopathic. The severity of disease appears to be strain dependent. Cytopathogenic effects do not correlate with virulence as non-cytopathic BVDV-2 is associated only with Hemorrhagic Disease, Bovine.
