“…Another important field for biomedical application of bacteriocins from B. thuringiensis (morricin, kurstacin, kenyacin, entomocin and tolworthcin) is animal health. These bacteriocins were included in the study to determine their antagonism against pathogenic strains of S. aureus isolated of milk from diseased cows mastitis, confirming an high antibacterial activity (Barboza-Corona et al, 2009). Also these bacteriocins are effective against pathogens isolated from bovine clinical and subclinical mastitis, because it inhibit the growth of multiantibiotic resistance bacteria such as Staphylococcus agnetis, Staphylococcus equorum, Streptococcus uberis, Brevibacterium stationis and Brachybacterium conglomeratum (León-Galván et al, 2015).…”

Bacteriocins are potent antimicrobial peptides produced by every bacterial and archeal species reported to date. The most studied are bacteriocins produced by lactic acid bacteria (LAB) and many species of Bacillus. Knowledge on the classification, biosynthesis and transport of these peptides is changing continually because the discovery and characterization of new bacteriocins increases, thus, the research reports increase at the same rate. The bacteriocins are considered the most promising molecules with enormous possibilities and realities for the design of improved antibiotics possessing specific characteristics, mostly against antibiotic resistant bacteria. Here, current information on the generalities, classification proposals, biosynthesis and transport systems involved in the bacteriocins secretion is review. Finally, this review will focus on the new approaches for its application in veterinary medicine and human health.

“…This assessment demonstrated that all bacteria isolated were susceptible to the five bacteriocins, mainly to Morricin 269 and Kurstacin 287 followed by Kenyacin 404, Entomocin 420 and Tolworthcin 524. It is important to remark that S. aureus strains tested were mainly resistant to traditional antibiotics used in the mastitis treatment (Barboza-Corona et al 2009a).…”

Bacillus thuringiensis is the most important entomopathogenic microorganism, owing to its insecticidal crystal proteins (Cry) that are nontoxic to the human beings and represent the hallmark of this bacterium. Most of the studies performed with this microorganism are focused to understand the role of Cry proteins in toxicity, mainly because these components constituted the toxic molecules of its commercial products. B. thuringiensis produces several metabolites with potential applied uses, in particular, chitinolytic enzymes and bacteriocins are two types of proteins produced by different subspecies of this microorganism that could expand the perspective of application of this extraordinary bacterium. In this chapter, we review the different kinds of chitinases that are synthesized by B. thuringiensis, their roles in nature, and their applications in environment, agriculture and food industry. Additionally, we analyze bacteriocins of B. thuringiensis reported to date, how to enhance their production, and the methods for screening the bacteriocin activity. Finally, the future challenges and prospects of the antimicrobial peptides as biopreservatives, antibiotics, and nodulation factors are showed.

“…Also, AMPs produced by S. aureus, S. epidermidis and Streptococcus gallolyticus have been tested against strains of both S. aureus and Streptococcus species isolated from bovine mastitis (Varella et al, 2007;Pieterse et al, 2008). Finally, B. thuringiensis AMPs have showed inhibitory action against S. aureus isolates from bovine mastitis (Barboza-Corona et al, 2009). From a non antimicrobial medical perspective, AMPs such as cinamicin may have different biomedical applications, because this peptide inhibits the function of phospholipase A2 and the angiotensin converting enzyme, which are involved in the immune system and in maintaining blood pressure in humans, respectively; so that they could be used in inflammatory processes and in blood pressure regulation (Ennahar et al, 2000) ( Table 2).…”
