To date there are no clear criteria to determine whether a microbe is susceptible to biocides or not. As a starting point for distinguishing between wild-type and resistant organisms, we set out to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) distributions for four common biocides; triclosan, benzalkonium chloride, chlorhexidine and sodium hy...

Chronic Helicobacter pylori disease is reduced with Allium vegetable intake. This study was designed to assess the in vivo anti-H. pylori potential of a variety of garlic substances. The garlic materials all showed substantial but widely differing anti-H. pylori effects against all strains and isolates tested. The MICs (range, 8 to 32 microg/ml) and minimum bactericidal concentrations (MBCs) (r...

More than 20% of the world's biodiversity is located in Brazilian forests and only a few plant extracts have been evaluated for potential antibacterial activity. In the present study, 705 organic and aqueous extracts of plants obtained from different Amazon Rain Forest and Atlantic Forest plants were screened for antibacterial activity at 100 microg/ml, using a microdilution broth assay against...

Hexane, chloroform, ethyl acetate and methanol extracts of Azima tetracantha were screened for their antimicrobial activity against human pathogenic bacterial and fungal strains. Antimicrobial activity was carried out by disc diffusion method, determination of minimum inhibitory concentrations (MIC), minimum bacterial concentrations (MBC) and minimum fungicidal concentrations (MFC) against thre...

Biofilms cause chronic infections that are difficult to treat because of the resistance microorganisms inside them. The goal is assess killing potential cefotaxime against Escherichia coli in biofilms obtained from clinical isolates kept microbiology laboratory Dr. Soetomo Surabaya Hospital. study was conducted by experimental design. Two steps challenged bacterial applying planktonic state and...
