BACKGROUND One major problem of ABE (acetone, butanol and ethanol) fermentation is high oxygen sensitivity of Clostridium acetobutylicum. Currently, no single strain has been isolated or genetically engineered to produce butanol effectively under aerobic conditions. In our previous work, a symbiotic system TSH06 has been developed successfully by our group, and two strains, C. acetobutylicum TS...
Tyrophagus putrescentiae (Schrank, 1781) is an emerging source of allergens in stored products and homes. Feces proteases are the major allergens of astigmatid mites (Acari: Acaridida). In addition, the mites are carriers of microorganisms and microbial adjuvant compounds that stimulate innate signaling pathways. We sought to analyze the mite feces proteome, proteolytic activities, and mite-bac...
باسیلوس سرئوس در شیر خشک نوزادان: یک مطالعه در اداره کل آزمایشگاههای کنترل غذا و داروی وزارت بهداشت
Background: Bacillus cereus spores distribute widely in nature and can be isolated from different kinds of foods. This bacterium can produce diarrhea and emetic enterotoxins and syndromes. As infants are known to be more susceptible to B. cereus infection due to their incomplete intestinal flora and fast growth of this bacterium during consumption, it is very important to investigate the presen...
مقدمه: Bacillus cereus باکتری غذازاد و اسپورداری است که اغلب در فرآوردههای غذایی مانند گوشت، سبزیجات، سوپ، برنج، شیر و سایر فرآوردههای لبنی میتواند تکثیر نماید. استفاده از اسانسهای گیاهی از جمله اسانس آویشن شیرازی و دارچین به عنوان نگهدارندههای طبیعی برای غذا رشد بسیاری از باکتریهای بیماریزا را مهار میکنند. هدف: هدف از این تحقیق ارزیابی اثر ضدمیکروبی اسانس دارچین و آویشن شیرازی علیه ب...
Fatal sepsis during chemotherapy-induced neutropenia is the most severe complication of which physicians must be keenly aware. Common bacterial pathogens in neutropenic patients usually include gram-positive cocci such as coagulase-negative staphylococci, Staphylococcus aureus, Enterococcus species, and gram-negative rods such as Escherichia coli, Klebsiella species, Enterobacter species, and P...
This article reports the results of studying three novel bacteriophages, JL, Shanette, and Basilisk, which infect the pathogen Bacillus cereus and carry genes that may contribute to its pathogenesis. We analyzed host range and superinfection ability, mapped their genomes, and characterized phage structure by mass spectrometry and transmission electron microscopy (TEM). The JL and Shanette genom...
materials and methods two-hundred pasteurized (n = 100) and nonpasteurized (n = 100) cheese samples were collected. the initial isolation was performed on pemba specific medium. antibiotic susceptibility testing was performed using several antibiotic disks, according to the guidelines of the clinical laboratory and standards institute. specific primers amplifying the hbla enterotoxin-encoding g...
The Bacillus cereus emetic pathotype is responsible for important food-borne intoxications. Here, we describe the complete genome sequence of bacteriophage Deep-Blue, which is able to infect emetic strains of B. cereus Deep-Blue is a 159-kb myophage of the Bastille-like group within the Spounavirinae.
Bacillus cereus C1L, a plant growth-promoting rhizobacterium, provides protection against fungal pathogens in monocot plants. To gain new insights into the biocontrol mechanisms used by this rhizobacterium, we determined the complete genome sequence of B. cereus C1L. One chromosome and three plasmids were identified with a total size of ~6.0 Mb.
The Bacillus cereus group bacteriophage TsarBomba, a double-stranded DNA Myoviridae, was isolated from soil collected in Saratov, Russia. TsarBomba was found to be similar to Bacillus phages BCP78 and BCU4, and to have a wide host range among Bacillus cereus group species.
