Relationship between milk lactoferrin and etiological agent in the mastitic bovine mammary gland

Abstract

Bovine mastitis is one of the most deleterious diseases for dairy herds and is mainly caused by contagious and environmental bacterial pathogens. Among contagious bacteria, Staphylococcus aureus is the most prevalent, whereas the main environmental mastitis pathogens are Streptococcus uberis and Escherichia coli. Bovine lactoferrin (bLF) is an approximately 80-kDa glycoprotein present in milk that participates in the innate response of the mammary gland against bacterial infection. The objectives of the current study were to analyze potential changes in bLF milk concentration, which would constitute a response of the mammary gland toward mastitis induced by different etiologic agents, and to evaluate a possible relation between this response and pathogen susceptibility to bLF. Microbiology analysis and bLF quantification in milk from different bovine mammary gland quarters were performed. Infected quarters presented greater concentrations of bLF compared with those from microbiologically negative quarters. Analysis of individual pathogen contributions showed that most of this increase was attributable to Strep. uberis intra-mammary infection. The ability of mammary gland cells to synthesize bLF in response to Strep. uberis chal...Continue Reading

Bacterial Cell Wall Structure (ASM)

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
