قرارگیری میکروارگانیسم ها در ساختاری به نام بیوفیلم موجب حفاظت سلول ها در برابر ترکیبات ضد میکروبی شده و مقابله با این ساختار ها را دشوار می نماید. از آن جا که میکروارگانیسم های مولد بیوفیلم عامل بسیاری از مشکلات در صنعت و پزشکی می باشند، دستیابی به شیوه های جدید برای حذف و مهار این ساختار ها ضروری است. در این پژوهش 17 گیاه انتخاب و تاثیر عصاره های الکلی آن ها بر باکتری های staphylococcus aure...

Aiming to develop a DNA marker specific for Bacillus anthracis and able to discriminate this species from Bacillus cereus, Bacillus thuringiensis, and Bacillus mycoides, we applied the randomly amplified polymorphic DNA (RAPD) fingerprinting technique to a collection of 101 strains of the genus Bacillus, including 61 strains of the B. cereus group. An 838-bp RAPD marker (SG-850) specific for B....

Food poisoning laboratories identify Bacillus cereus using routine methods that may not differentiate all Bacillus cereus group species. We recharacterized Bacillus food-poisoning strains from 39 outbreaks and identified B. cereus in 23 outbreaks, B. thuringiensis in 4, B. mycoides in 1, and mixed strains of Bacillus in 11 outbreaks.

Genome features of the Bacillus cereus group genomes (representative strains of Bacillus cereus, Bacillus anthracis and Bacillus thuringiensis sub spp. israelensis) were analyzed and compared with the Bacillus subtilis genome. A core set of 1381 protein families among the four Bacillus genomes, with an additional set of 933 families common to the B. cereus group, was identified. Differences in ...

Fifty nine samples of raw milk, 60 samples of pasteurized milk, 24 cream, 39 butter, 27 curd, 19 peda, 21 paneer and 20 skim milk powder samples were analyzed for the presence of different Bacillus species and a total of 182 isolates were obtained. The isolates were identified as Bacillus subtilis (51), Bacillus megaterium (39), Bacillus cereus (28), Bacillus licheniformis (32), Bacillus coagul...

The identification of Bacillus anthracis involves its differentiation from other aerobic sporeformers, particularly Bacillus cereus. Smith et al. (1952), in a study of aerobic sporeforming bacteria, concluded that B. anthracis is a pathogenic variety of B. cereus. They also stated that strains of B. anthracis which had lost their virulence could not be differentiated from B. cereus. This appare...
