Antimicrobial Activity of Aflatoxins

Journal of Bacteriology, 1967
Antimicrobial activity of a crude aflatoxin preparation and of aflatoxin B 1 was studied. They were found inactive against common gram-positive and gram-negative bacteria at a concentration of 100 μg/ml. Both samples of aflatoxin did, however, exhibit antimicrobial activity, though narrow and limited, against ...

Antimicrobial Activity of Heparin

Journal of Clinical Microbiology, 1980
Single clinical isolates of eight species of microorganisms were incubated in solutions of heparin and brain heart infusion broth at various concentrations to determine the possible antibacterial effect of heparin. At heparin concentrations ranging from 12.5 to 400 U/ml, the effect on Escherichia coli, Pseudomonas aeruginosa ...

Antimicrobial activity of spices

International Journal of Antimicrobial Agents, 1999
Spices have been shown to possess medicinal value, in particular, antimicrobial activity. This study compares the sensitivity of some human pathogenic bacteria and yeasts to various spice extracts and commonly employed chemotherapeutic substances. Of the different spices tested only garlic and clove were found to possess antimicrobial activity.

Antimicrobial Activity of Chlormerodrin

Journal of Pharmaceutical Sciences, 1979
A radiochemical study for antimicrobial activity of chlormerodrin was performed using some commonly occurring nonpathogenic and pathogenic microorganisms. Chlormerodrin concentrations of 15-35 and 20-45 microgram/ml of the culture medium were microbiostatic and microbicidal, respectively.

Antimicrobial activity ofo-carboranylalanine

Amino Acids, 1999
Functionalized polyhedral carboranes, including amino acid analogs, have unique physicochemical properties and are used as experimental anticancer agents. However, our current knowledge on their effect in nonmammalian biological systems is limited. We investigated the activity spectrum in vitro of o-carboranylalanine (o-Cba), considered to be a highly ...

Antimicrobial Activity Methods

2023
Plant extracts are widely utilized for their antimicrobial effect, alone or in combination with traditional drugs. However, the current global lack of harmonization on the assays used to investigate their biological effect makes the result comparison very challenging. In the present chapter, we highlight the variables used for the antimicrobial testing,

Antimicrobial Activity of Tibezonium (TBZ)

Chemotherapy, 1977
The activity in vitro of tibezonium (Rec 15-0691), a new 1,5-benzodiazepine derivative, has been investigated. The drug was found active especially against Streptococcus, Diplococcus and Corynebacterium strains which are agents of oropharyngeal diseases.

Antimicrobial activity of Evodia elleryana

Fitoterapia, 2000
The methanol extracts of Evodia elleryana, leaves, stem wood, stem bark, root wood and root bark were partitioned (petrol, dichloromethane, ethyl acetate). All obtained fractions showed a broad spectrum of antibacterial activity, while none were active against tested moulds.

Antimicrobial activity of ultrasonic cleaners

Journal of Hospital Infection, 2005
This study assessed the antimicrobial activity of two cleaning solutions and tap water after varying periods of use in one ultrasonic cleaner. Testing involved filling the cleaner's tank and a centred glass beaker with the same test solution. An aluminium foil strip test first determined that no significant differences in cavitational activity existed ...

Antimicrobial activity of quaternized heteroxylans

World Journal of Microbiology and Biotechnology, 1994
A series of quaternized D-xylan polysaccharides, differing in the structural features of their macromolecular backbone, were tested for antimicrobial activity against Staphylococcus aureus, Enterococcus faecalis, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Serratia marcescens and Saccharomyces cerevisiae.
