Bacteria pathogenicity

Common definitions of the term disinfection usually aim at its medical aspects related to transmissible diseases and to the killing or irreversible inactivation of the disease-causing organisms by use of chemical agents or physical procedures. This includes the destruction of infectious or other undesirable bacteria, pathogenic fungi or vimses and protozoa on surfaces or any inanimate objects (Block, 1993, Harke, 1987). Thus, disinfection of water, air or surfaces should produce a... 

CNC Antistat 2 is a quaternary ammonium bromide. It is a light colored amber solution. It may be used on cotton, wool, viscose and beraberg. Textiles treated with CNC Antistat 2 are resistant to mildew and decomposition by bacteria. Pathogenic organism are inhibited by the bacteriostatic qualitites imparted to fabrics. 

If host invasion is a dead-end for trophozoites of E. histolytica, what has maintained the invasive phenotype in a fairly competitive population of intestinal microorganisms One possibility is that the invasive phenotype confers other adaptive advantages. The release of proteolytic enzymes and cytolytic factors may enhance degradation and uptake of nutritional molecules from host or bacteria. Pathogenicity and invasiveness not only correlate with the release of specific virulence factors but also enhanced phagocytosis. With controversial exceptions, only pathogenic (potentially invasive) isolates have been successfully weaned to long-term and stable axenic culture. 

The primary sources of bacteria in water are human and animal wastes, seepage or discharge from septic tanks, sewage treatment facilities, and natural soil and plant bacteria. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. The EPA requires that aU public water suppliers regularly test for coliform bacteria and deliver water that meets the EPA standards. The EPA Maximum Contaminant Level (MCL) for coliform bacteria in drinking water is zero total cohforms per 100 mL of water (56).

The task of disinfectants is to kill or irreversibly inactivate infectious or other undesirable bacteria, pathogenic fungi, or viruses on surfaces or inanimate objects. Sanitizers are applied to reduce the number of living bacteria, fungi or viable viruses on inanimate surfaces, in water or in the air. Disinfectants and sanitizers may additionally have cleaning properties, but contrary to the large number of normal industrial and institutional cleaning products they contain microbicides.
