Parasites Eggs, biofilm and heavy metals. A.K.
The eggs of the ascaris suum of the pig cannot be destroyed with bleach or chlorine, because they support a PH of 2 to 11.5, these eggs can remain in the soil for up to 5 years without being destroyed, the worms carry a shell, and this shell It is covered by a mucosa called biofilm. To be more resistant and protect the worm, this biofilm needs heavy metals, and if the body has heavy metals that the worms can use, they will be more resistant and difficult to eliminate.
Definition of BIOFILM
can be defined as a set of microorganisms adhered to a surface, encapsulated in a hydrated polymeric matrix that is collectively called "matrix" or "extracellular polymeric substance" (EPS). The matrix is synthesized by the microorganisms themselves and is made up of approximately 95% water, together with polysaccharides, proteins, nucleic acids, minerals, etc. (Carpentier and Cerf, 1993; Costerton et al., 1995). Bacterial biofilms represent a prokaryotic survival strategy. The main function of a biofilm matrix is to allow bacteria to remain united and protected against external changes such as fluctuations in humidity, changes in temperature, the action of disinfectant products, the presence of antibiotics, antibodies, bacteriophages, etc.; in addition to providing the microorganisms with a concentration of necessary nutrients and facilitating the elimination of bacterial residues (Davey and O'toole, 2000; Hall-Stoodley and Stoodley, 2005). The structure of a biofilm is conditioned by biological, physical and chemical factors. Those factors include hydrodynamic forces, the viscosity of the medium in which it is formed, and the composition of the matrix. A biofilm can contain one or more bacterial species, where the adhesion and metabolic remains of one species can serve for the development of other species. These characteristics allow biofilms to develop on hydrophobic, hydrophilic, biotic or abiotic surfaces, which present a hydrated environment; and if it is not abundant, that they can conserve a minimum presence of nutrients necessary for their development (Marshall, 1992; Sauer et al., 2003). The ability to form biofilms does not seem to be restricted to some specific groups of microorganisms and it is considered that under suitable environmental conditions, the vast majority of bacteria can exist within biofilms (Donlan, 2002; Thomas and Nakaishi,
