Smart active antibiotic nanocarriers with protease surface functionality can overcome biofilms of resistant bacteria

Coexistence of antibiotic-producing and antibiotic-sensitive bacteria in biofilms is mediated by resistant bacteria.

Antibiotic-sensitive bacteria have been found to coexist with antibiotic-producing bacteria in biofilms, but little is known about how the former develop in such an environment. Here we isolated pyocyanin-sensitive bacteria belonging to the genus Brevibacillus from a biofilm derived from soil extract and based on the preestablished biofilm of a pyocyanin producer, Pseudomonas aeruginosa strain ...

Antibiotic resistance of bacteria in biofilms.

Bacteria that adhere to implanted medical devices or damaged tissue can encase themselves in a hydrated matrix of polysaccharide and protein, and form a slimy layer known as a biofilm. Antibiotic resistance of bacteria in the biofilm mode of growth contributes to the chronicity of infections such as those associated with implanted medical devices. The mechanisms of resistance in biofilms are di...

Impacts of Antibiotic-Resistant Bacteria

Public Health Implications of Antibiotic-Resistant Bacteria Associated with Suya Spices in Nigeria

Background: The emergence and re-emergence of antibiotic-resistant foodborne bacteria call for concerted efforts, especially in developing countries. Spices have been employed traditionally to improve the aroma and flavour of foods; however, they could  serve as reservoirs for the spread of potential pathogenic organisms. This study aims to investigate the public health implications of antibiot...

SCREENING FOR ANTIBIOTIC RESISTANT BACTERIA IN URINE SAMPLES

Chronic urinary tract infections are often caused by antibiotic resistant bacteria. In some of these cases, prediction of the most effective antibiotic (s) may urgently be needed. This can not be achieved unless the nature and patterns of the resistance to antibiotics among the pathogenic bacteria has been described earlier. The urine samples that reached the laboratory of Shaheed Mustafa K...
