Antibacterial and wound healing potential of biosynthesized zinc oxide nanoparticles against carbapenem-resistant Acinetobacter baumannii: an in vitro and in vivo study.

Carbapenem-resistant Acinetobacter baumannii denotes a significant menace to public health, and it mandates an urgent development of new effective medications. Here, we aimed to estimate the efficiency of the zinc oxide nanoparticles (ZnO NP) biosynthesized from Arthrospira maxima (Spirulina) both in vitro and in vivo. Carbapenem-resistant A.

Potential antivirulence and antibiofilm activities of sub-MIC of oxacillin against MDR S. aureus isolates: an in-vitro and in-vivo study.

Background: Multi-drug resistant Staphylococcus aureus is one of the most common causes of nosocomial and community-acquired infections, with high morbidity and mortality. Treatment of such infections is particularly problematic; hence, it is complicated by antibiotic resistance, and there is currently no reliable vaccine. Furthermore, it is well known that S.

Antimicrobial activity of bacteriocins produced by Enterococcus isolates recovered from Egyptian homemade dairy products against some foodborne pathogens.

The increasing mandate for fresh-like food products and the possible hazards of chemically preserved foods necessitate the search for alternatives. Bacteriocins represent a promising food biopreservative. In the present study, one hundred enterococci isolates recovered from Egyptian raw cow milk and homemade dairy products were screened for bacteriocin production.

Production and immobilization of alpha-amylase from Bacillus subtilis.

Alpha-amylase production by Bacillus subtilis was studied under different cultivation conditions. The maximum alpha-amylase production occurred after an incubation period of 48 h, temperature 40 degrees C and pH 7.5.
