Kinetics of antimicrobial activity

The Journal of Pediatrics, 1986
Assessment of antimicrobial activity from standard in vitro minimum inhibitory and minimum bactericidal concentration determinations alone is incomplete. Rate of bacterial killing, effect of increasing concentration, sub-MIC effects, and degree of suppression of bacterial growth after limited exposure (post-antibiotic effect) more precisely describe ...

Antimicrobial activity of obioactin

Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1984
A newly developed enzyme-hydrolyzed toxoplasma-hyperimmune bovine serum preparation, Obioactin , was examined for its anti-microbial and related actions against heterologous protozoa, bacteria, and viruses both in-vivo and in-vitro. An appreciable efficacy of Obioactin in a combination with nifurtimox, Lampit was observed in experimental Trypanosoma ...

Antimicrobial activity of cecropins

Journal of Antimicrobial Chemotherapy, 1996
The lytic peptides, cecropins, were originally isolated from the haemolymph of the giant silk moth, Hyalophora cecropia and possess antibacterial and anticancer activity in vitro. This study investigated the antimicrobial activity of these peptides against human pathogens using standardised assay techniques, and the activity of cecropin B on outer and ...

Antimicrobial activity of antiproteinases

Biochemical Society Transactions, 2001
Low-molecular-mass neutrophil elastase inhibitors have been shown to be important in the control of lung inflammation. In addition to inhibiting the enzyme neutrophil elastase, these low-molecular-mass compounds (10 kDa) have been shown to have other activities.

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,
