Nanomaterials are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects.  The present report signifies a contribution to the study of the toxic effects of silver nanoparticles on   E. coli cells, which is a model organism of anthropogenic pollution. The toxicity of nanoparticles depends on their chemical and surface properties, shape and ...

The microorganisms have been usual noted as the major cause of delayed wound healing. Pseudomonas aeruginosa is the most common pathogen causing these infections. Silver nanoparticles (AgNPs) show ample antibacterial activities. In present study, the effect of AgNPs alone and in combination with tetracycline investigated on inoculated wounds with Pseudomonas aeruginosa in mice. Twenty mice anes...

Background: Bacterial resistance to the commonly used antibacterial agents is an increasing challenge in the medicine, and a major problem for the health care systems; the control of  their spread  is a constant challenge for the hospitals. Objectives: In this study, we have investigated the antimicrobial activity of the Zinc Oxide nanoparticles against clinical sample; Yersinia intermedia bact...

It is known that the major etiologic agent of pseudomembranous colitis in man is Clostridium difficile. With respect to traditional use of almond paste in the treatment of infantile diarrhea, we studied the effects of the aqueous extract of Amygdalus communis (AEAC) on the growth and toxin production of Clostridium difficile in culture medium and the rabbit ligated ileal loop. Three groups...

OBJECTIVES The efficacy of rifampicin-loaded polymeric microspheres (RPLGA) delivered to guinea pigs infected with Mycobacterium tuberculosis (H37Rv) was compared with a daily dose of nebulized rifampicin suspension. METHODS Aerosol-infected animals were subjected to multiple dose or single dose treatment with RPLGA, PLGA microspheres or micronized rifampicin suspension aerosols. For comparis...

nanomaterials (nms) are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects.  the present report signifies a contribution to the study of the toxic effects of silver nanoparticles (ag nps)  on   e. coli cells, which is a model organism of anthropogenic pollution. the toxicity of nanoparticles depends on their  chemical and surface prope...

the present study investigates the possibility of enriching adult artemia franciscana with singular or combined administration of pediococcus acidilactici and fructooligosaccharide (fos). the experiment was conducted in a completely randomized design with four treatments, including synbiotic, p. acidilactici +fos (t1), probiotic, p. acidilactici (t2), prebiotic, fos (t3) and control (t4). to ev...

Background: Bacterial blight pathogen (Xanthomonas axonopodis pv. cyamopsidis) of clusterbean causes considerable damage every year during Kharif season and sometimes become very severe, which results in heavy loss grain yield. Methods: On the basis vitro studies, most effective botanical, antibiotic fungicide at highest concentration were used as individual its combinations field experiment tw...
