Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...

The Gram stain classifies most bacteria into one of two groups, Gram-negative or Gram-positive, based on the composition their cell walls [...]

background lactoferrin is a multipurpose protein of the transferrin domestic. it is a spherical glycoprotein with a molecular weight of about 80 kda which is widely found in secretory discharges, such as milk, saliva, tear, and nasal secretions. lactoferrin is also found in secondary granules of polymorphonuclear leukocytes (pmn) and is released by some acinar cells. it also shows antibacterial...

 SUST, ICERIE. Abstract: — In this paper, we describe a research method that generates Bangla word clusters on the basis of relating to meaning in language and contextual similarity. The importance of word clustering is in parts of speech (POS) tagging, word sense disambiguation, text classification, recommender system, spell checker, grammar checker, knowledge discover and for many others Nat...

gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. this study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. enriched and specific media used for isolation of bacteria. identification of isola...
