The compound exhibited good antibacterial effect towards gram negative species when compared to the standard ciprofloxacin. At the same time the analogue was retaining antibacterial activity towards gram positive species when compared to standard ciprofloxacin. The molecular docking studies showed a good correlation between their

spreading around. The article starts off by expressing the valid point of the spreading of harmful diseases. A 12-year-old boy named Omar Rivera‚ from Brooklyn‚ died after getting infected by a disease. This disease was Methicillian Resistant Staphylococcus Aureus‚ otherwise known as MRSA. This bacterium is resistant to one of the most potent drug classes in the current antibiotic arsenal. Because of these dangerous bacteria’s developing resistance to antibiotics‚ it puts the risk of mortality higher

Some bacteriocins produced by lactic acid bacteria‚ such as nisin‚ inhibit not only closely related species but are also effective against food-borne pathogens and many other gram-positive spoilage microorganisms. For this reason‚ bacteriocins have attracted considerable interest for use as natural food preservatives in recent years (Rattanachaikunsopon et al.‚ 2010). Since bacteriocins are isolated from foods such as meat and

Control by Antibiotics and Antiseptics Lab Report Georgia State University Introduction The fact that each bacterial species‚ and even some of their respective strains‚ responds uniquely to a given antimicrobial makes it necessary to have methods‚ which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By

Certainly‚ the high adaptability of B.subtilis to environmental changes and insults stands at the basis of its success‚ not only in its character but also in marketable applications.

The solvents that were used in the experiment were ethanol and water to extract the seeds of moringa (Moringa oleifera) and the pods of soursop (Annona muricata) with a ratio of 1:50 and 1:10 and a concentration of 50‚ 100‚ 150 and 200 μL.

numbers of B. cereus in a food is indicative of active growth and proliferation of the organism and is consistent with a potential hazard to health. The diagnosis of B. cereus can be confirmed by the isolation of more than 105 B. cereus organisms per gram from epidemiologically implicated food‚ but such testing is often not done because the illness is relatively harmless and usually self-limiting 1.
