Enhancing the natural toxicity of Salmonella Typhimurium towards tumours

Biofilm formation by Salmonella enterica serovar Typhimurium colonizing solid tumours.

Systemic administration of Salmonella enterica serovar Typhimurium to tumour bearing mice results in preferential colonization of the tumours and retardation of tumour growth. Although the bacteria are able to invade the tumour cells in vitro, in tumours they were never detected intracellularly. Ultrastructural analysis of Salmonella-colonized tumours revealed that the bacteria had formed biofi...

inhibitory effects of several essential oils towards salmonella typhimurium, salmonella paratyphi a and salmonella paratyphi b

plant essential oils are natural products extracted from plants and because of their antimicrobial properties can be used as natural additives in foods. they are also useful for decontamination of food-borne pathogens and can be a safe additive in foods. the antimicrobial activities of essential oils belonging to saturiea hortensis, thymus vulgaris, mentha polegium, cuminum cyminum, lavandula o...

Separation of Salmonella Typhimurium Bacteria from Water Using MWCNTs Arrays

In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...

Innate secretory antibodies protect against natural Salmonella typhimurium infection

The production of IgA is induced in an antigen-unspecific manner by commensal flora. These secretory antibodies (SAbs) may bind multiple antigens and are thought to eliminate commensal bacteria and self-antigens to avoid systemic recognition. In this study, we addressed the role of "innate" SAbs, i.e., those that are continuously produced in normal individuals, in protection against infection o...
