2002 | Phenotypical and molecular differentiation among resistant and susceptible Pseudosuccinea columella stumps to Hepatic Fasciola.
Main author: Alfredo Gutiérrez Amador.

The work has high scientific novelty and originality since it allows, for the first time in our country, establishing phenotypical and molecular differentiation among resistant and susceptible mollusks of any species, which contributes in a decisive way to the cognizance and subsequent control of Hepatic Fasciola. A remarkably original aspect was the demonstration of the existence of phenotypical and molecular markers related to the resistance and susceptibility of Pseudosuccinea columella to Hepat ic Fasciola. We consider that these discoveries have a high social impact due to the damages caused by the presence of these trematodes in the country's cattle population and even by its incidence in human beings.

Another important aspect is that this study allows recognizing the resistant populations from the susceptible populations, without needing to proceed to their testing, and it also allowed determining the resistance mechanism. All these aspects also place the work as a methodological document for the subsequent identification of other congeners. The work has been published in a prestigious magazine, and has been endorsed by Dr. André Théron, honorable researcher from the National Center for Scientific Research in France.
