Opportunistic pathogens are a worldwide cause of mortality and morbidity, and infections with intrinsically antibiotic-resistant pathogens have a large clinical, social and economic impact. Bacteria belonging to the Burkholderia cepacia complex (Bcc), ubiquitous in natural and industrial environments, are notorious pathogens for individuals with cystic fibrosis (CF). In addition, Burkholderia c...

Phagocytosis, which is essential for the immune response to pathogens, is initiated by specific interactions between pathogens and cell surface receptors expressed by phagocytes. This study identifies triggering receptor expressed on myeloid cells 2 (TREM-2) and its signaling counterpart DAP12 as a molecular complex that promotes phagocytosis of bacteria. Expression of TREM-2-DAP12 enables nonp...

The study was carried out to isolate and identify the common Bacteria causing respiratory tract infections among patients attending Aminu Kano Teaching Hospital between August and October, 2011, and the current sensitivity patterns of the isolated bacteria to common commercially antibiotic prepared disc. Fourty three (43) bacterial pathogens were isolated from two hundred (200) samples collecte...

background: there is a conserved portion in the 16s rrna gene of bacteria which can be amplified by the universal pcr method. this fragment is 996 bp in length. in this method, only one set of universal primers is used for the amplification of the conserved region of the 16s rrna gene, in common bacterial pathogens. therefore, using the universal pcr method, these bacteria are detectable only b...

Here, we review sexually transmitted diseases (STDs) caused by pathogenic bacteria and vaginal infections which result from an overgrowth of opportunistic bacterial microflora. First, we describe the STDs, the corresponding pathogens and the antimicrobials used for their treatment. In addition to the well-known diseases caused by single pathogens (i.e., syphilis, gonococcal infections, and chla...

For as long as the human blood-brain barrier (BBB) has been evolving to exclude bloodborne agents from the central nervous system (CNS), pathogens have adopted a multitude of strategies to bypass it. Some pathogens, notably viruses and certain bacteria, enter the CNS in whole form, achieving direct physical passage through endothelial or neuronal cells to infect the brain. Other pathogens, incl...

there is a long period between harvested beets and their transfer to the sugar factory. sugar beet crop is damaged and injured during harvest and transport which provides a suitable place for various saccharoliytic microorganisms growth in terms of temperature, moisture, ph and glucose concentration. in this study, samples were randomly selected from the roots stored in spring 2010 and also the...

The emergence of antibiotic-resistant bacteria is a pressing public health concern, highlighting the need for alternative approaches to control bacterial infections. Promising include development therapeutic vaccines and utilization innate immune activation techniques, which may prove useful in conjunction with antibiotics, as well other antibacterial modalities. However, should be fast self- o...

this study has been done to survey of solvent system effect on extraction of grape seed extract and its antimicrobial properties. for this purpose, grape seed extracts were extracted with six different solvent systems. minimum bactericidal concentration (mbc) of extract on six spoilage and food-born pathogens was determined. the results indicated that mbc of different extracts have no significa...

The beverage industry has been a heavy producer of organic pollution. The major contaminants found in waste are biodegradable organic compounds, volatile organic compounds, toxic metals, and recalcitrant xenobiotics, suspend solids, nutrients (Nitrogen and Phosphor) Microbial pathogens and parasites. Activated sludge flocs contain a wide range of microorganisms such as bacteria, Fungi, yeast, v...
