interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (hcl). the aim of the present study is to apply yeast strain for secreting human ifnα2b fol...

Background: Leishmania is a pathogenic parasite which infects mononuclear cells in vertebrate hosts. Different strategies have been taken to develop immunity against Leishmania . DCs loaded with immunogenic antigen have resulted in different levels of Th1-type immune response and cytotoxic T lymphocytes (CTL) activity. Objective: To evaluate the potency of DCs primed with soluble Leishmania mex...

conclusions based on our findings, p. aerugionsa is a major causative agent of wound infections and amikacin could be considered as a more effective antibiotic for treatment of the burned patients. background nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. objectives this study was conducted to evaluate the ...

Epitope tagging has proven a useful method for monitoring recombinant proteins expressed in either prokaryotic or eukaryotic cells. For this purpose, the epitope should not be present on any of the host cell’s proteins, it should not interfere with either structure or function of the tagged protein, and the corresponding antibody must be of high specificity and affinity. To this day, only a few...

Colistin resistance in Acinetobacter spp. is increasing, resulting potentially untreatable nosocomial infections. Plasmid-mediated colistin of particular concern due to its low fitness cost and potential transferability other bacterial strains species. This study investigated the mechanism a clinical nosocomialis isolate from Cape Town, South Africa. A colistin-resistant A. was identified blood...

the biodegradation of secondary amines is particularly important due to their propensity for conversion either chemically or microbiologically to n-nitrosamines which are potent carcinogens. in this research, a weak gram-positive organism was isolated from river and identified as mycobacterium. this mycobacterium grows slowly and effectively utilizes piperazine as the sole source of organic, ca...
