Antibacterial and antioxidant activities of crude aerial part extracts of Satureja Punctata (Benth) Briq

This study evaluates the antimicrobial and antioxidant activities of the crude extract of an aerial part of Satureja punctata (Benth.) Briq. The dried aerial part of S. punctata (Benth.) Briq was extracted separately using aqueous, ethanol and n-hexane. The antibacterial activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa was assessed using disc diffusion method, and the minimum...

In vitro assessment of Leuconostoc mesenteroides zinc nanoparticles against Salmonella serovars recovered from broilers chickens

Salmonella serovars are responsible for a variety of acute and chronic diseases in poultry. Leuconostoc mesenteroides probiotic can exert antimicrobial activity by producing diverse fermentative metabolites with bactericidal or bacteriostatic activities such as lactic and acetic acids, fatty acids, hydrogen peroxide or diacetyl and antimicrobial proteins such as bacteriocins and peptidoglycan hydrolase enzymes. This...

Antibiotic resistance genes in diarrheagenic Escherichia coli (DEC) isolated from livestock organic wastes in Ouagadougou, Burkina Faso

Diarrheagenic Escherichia coli (DEC) are often disseminated through the fecal matter of livestock and waste products including slurry and manure. The study aimed to characterize archived DEC recovered from cattle fecal matter, manure and slurry for quinolone resistance and extended spectrum beta-lactamases (ESBLs) with focus on trends in antimicrobial susceptibility patterns. The susceptibility of the bacteria was...
