abstract objective: shallots are important part of the diet for many people and there is long-held belief in their health enhancing properties. the aim of this study was to determine antifungal activity of shallot against reference fungal strains. methods: alcoholic and aqueous extracts of shallot (allium hirtifolium) were tested for in vitro antifungal activities against aspergillus fumigatus,...

Background: Mentha piperita L. essential oils have different antibacterial activity. In the present study, we investigated the effect of &gamma–irradiation on the antibacterial activities of Mentha piperita L. essential oils in vitro and in vivo systems. Materials and Methods: The aerial parts of peppermint were irradiated in a cobalt60 source with 0, 10 and 25 kGy absorbed doses. Then, t...

23 We compared the efficiency of different drug susceptibility testing methods to detect 24 the rifampin (RIF) heteroresistance in Mycobacterium tuberculosis. Our data revealed 25 that broth dilution method found more resistance than MGIT (P=0.046) for low 26 resistance group. Similarly, broth dilution method was more sensitive to detect RIF 27 heteroresistance in subpopulation with slow grow r...

INTRODUCTION Microbiology laboratories must provide accurate blood culture reports with rapid turnaround time (TAT) to effectively manage patients with sepsis. In this study three methods are compared for reporting blood culture results: a manual method that included use of a serum separator tube (SST), the conventional manual, and an automated method for identification and susceptibility (ID/A...

A method was devised to test the growth-promoting ability of a broth medium. The "dilute to extinction" method determines the inoculum required to develop heavy turbidity in a broth with overnight incubation. A statistical method using Poisson distribution was used to show that a single Haemophilus cell can develop heavy turbidity in an optimal broth. The dilute to extinction method was used to...

In this study, we have evaluated the broth microdilution method (BMM) for susceptibility testing of Mycobacterium tuberculosis. A total of 43 clinical isolates of M. tuberculosis and H37Rv as a control strain were studied. All isolates were tested by the proportion method and the BMM for isoniazid (INH), rifampicin (RIF), streptomycin (STR), and ethambutol (ETM). The proportion method was carri...

We compared the efficiencies of different drug susceptibility testing methods in detecting rifampin (RIF) heteroresistance in Mycobacterium tuberculosis. Our data revealed that the broth dilution method found more resistance than MGIT did (P=0.046) for the low-resistance group. Similarly, the broth dilution method was more sensitive in detecting RIF heteroresistance in subpopulations with low g...

The biosynthetic peptide dolastatin 10 is currently in phase I and II cancer clinical trials. We evaluated the antifungal spectrum of dolastatin 10 and four structural modifications. In broth macrodilution assays, the peptides were fungicidal for American Type Culture Collection strains and clinical isolates (including fluconazole-resistant strains) of Cryptococcus neoformans but no other yeast...
