Application of toxic antibacterial agents is considered necessary to control prevalent fresh water microorganisms that grow in evaporative cooling water systems, but can adversely affect the environment and human health. However, natural antibacterial water chemistry has been applied in industrial cooling water systems for over 10 years to inhibit microorganisms with excellent results. The wate...

When a patient does not respond to antimicrobial agents (hereinafter, antibacterial agents), the drugs should not be changed before an attempt is made to discover the reason for ineffectiveness. 1 First, it is more practical to imagine the possibility that pneumonia-like infiltration may have occurred by a cause other than pathogenic microorganisms. In other words, a differential diagnosis such...

The antibacterial therapeutic area has been described as the perfect storm. Resistance is increasing to the point that our hospitals encounter patients infected with untreatable pathogens, the overall industry pipeline is described as dry and most multinational pharmaceutical companies have withdrawn from the area. Major contributing factors to the declining antibacterial industry pipeline incl...

We determined the in vitro antibacterial activity of ciprofloxacin against Vibrio cholerae O139 recently isolated from cholera patients in India. Ciprofloxacin showed excellent antibacterial activity against the O139 strains, and ciprofloxacin-resistant O139 strains were not observed. The lack of incidence of ciprofloxacin resistance in O139 strains may be because O139 strains appeared comparat...

− The aim of this research was to investigate the industrial application of Zanthoxylum schinifolium. Antibacterial activities of the n-hexane, methylene chloride (MC), ethyl acetate, and butanol fractions of Z. schinifolium were tested against Escherichia coli, Staphylococcus aureus and Helicobacter pylori. Among the fractions, the n-hexane and MC fractions showed the stronger antibacterial ac...

Actinopyga lecanora, a type of sea cucumber commonly known as stone fish with relatively high protein content, was explored as raw material for bioactive peptides production. Six proteolytic enzymes, namely alcalase, papain, pepsin, trypsin, bromelain and flavourzyme were used to hydrolyze A. lecanora at different times and their respective degrees of hydrolysis (DH) were calculated. Subsequent...

Substituted thiazolo ring-fused 2-pyridones, called pilicides, possess novel antibacterial properties and inhibit pilus assembly in Uropathogenic Escherichia coli. Recently, a small number of oxygen analogues of active pilicides have shown maintained ability to disrupt pilus assembly. Here an improved methodology for the synthesis of oxazolo ring-fused 2pyridones is presented, allowing dihydro ...
