Background Nasal epithelial cells are the first line of defence against invading microbes. In everyday life, we are constantly exposed to variety of bacteria and viruses, but not every exposure leads to a development of pro-inflammatory responses of nasal epithelium. Although triggering of an individual PRR is known to induce cell responses, it has become clear that the ultimate profile of cyto...
objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...
The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...
background and objectives: pathogen reduction technologies are among methods to eliminate transfusion transmitted infections. mirasol method using riboflavin in combination with ultraviolet rays is one of them. the aims of this study were to investigate the effectiveness of mirasol method to inactivate some model pathogens as well as examination of the sensitivity of plasma proteins after treat...
Controlling the microbiological quality of water is important for its uses. Microbiological requirements of drinking water ensure the absence of coliforms, but may indicate the potential presence of other potentially pathogenic microorganisms and viruses of fecal origin. A total of 36 water samples, representing the drinking water of the whole city of Aradan, Semnan, Iran, were randomly collect...
Viruses are dominant entities in the biosphere and parasitize all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In marine, soil and animal-associated environments, virus particles consistently outnumber cells by one to two orders of magnitude. It is estimated that 10 quintillion (1030) viral particles ...
screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...
background considering the high prevalence of bacterial vaginosis and its association with urinary tract infection in women and treatment of gynecologic problems occur when a high recurrence of bacterial vaginosis is often treated with antibiotics. objectives the purpose of this study was to investigate the inhibitory effect of lactobacillus reuteri on pathogenic bacteria isolated from women wi...
Probiotics are considered as living drugs that can reduce antibiotic consumption and increase human health development. Meanwhile, probiotics can adjust intestinal microflora, inhibiting the growth of pathogenic bacteria, antimicrobial agents, stimulate the immune system, balance of bile acids and ultimately inhibit the growth and reduce the number of harmful bacteria in the digestive system. ...
Plant diseases caused by numerous pathogens such as bacteria, viruses, and fungi are responsible for substantial economic losses in the agricultural industry worldwide. Specific, sensitive, efficient diagnostic tools have been developed worldwide to mitigate prevent pathogenic threat. The revolutionized from classical methods more advanced molecular approaches enzyme-linked immunosorbent assay ...
