Escherichia coli (E. coli) is a Gram-negative, facultative anaerobic, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded animals. Most of the E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination [1,2]. The harmless strains are part of the no...

in recent years due to changes in lifestyle and eating behavior of the human populations, disease caused by contaminated food has increased significantly. listeria monocytogenes, escherichia coli o157:h7 and salmonella enteric are three of the most important food borne bacterial pathogens and can lead to food borne diseases. also today wide spread of resistance to antibiotics among bacteria occ...

The gastrointestinal tract of the human and other mammals is populated by a vast and diverse group of microbes in a composite manner (Frank and Pace, 2008; Ito, 2005). Bacteria are the major population of the alimentary tract and this native microflora is commonly designated the gut microflora (Ito, 2005). Microbial flora present in the microenvironment of the gastrointestinal tract performs se...

CONTEXT Diarrhea is a common disease across the world. According to WHO, every year about two billion cases of diarrhea are reported in the world. It occurs mainly in the tropical regions and is a main cause of morbidity and mortality, particularly in young children and adults. EVIDENCE ACQUISITION One of the major causes of diarrheal diseases is bacteria; detection of pathogenic bacteria is ...

oscillating magnetic field pulses on the survival of certain selected pathogenic microorganisms of potatoes. The less resistant of the tested microorganisms proved to be the Ervinia carotovora and Streptomyces scabies bacteria. The tested fungus Alternaria solani proved to be the most resistant. When treating bacteria, it was found that their number was reduced by over 3 orders of magnitude, an...

Vibrio parahaemolyticus is a food-borne pathogen that naturally inhabits both marine and estuarine environments. Free-living protozoa exist in similar aquatic environments and function to control bacterial numbers by grazing on free-living bacteria. Protozoa also play an important role in the survival and spread of some pathogenic species of bacteria. We investigated the interaction between the...

conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...

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...
