Influencia de Salmonella pullorum y S. gallinarum en la producción avícola y la salud pública

The quality of the food we consume has become one of the main public health problems worldwide, since it is the gateway for pathogens and vectors for the transmission of various diseases. It was estimated that 17.9% of diseases transmitted by food consumption are related to poultry, and 19% of these diseases are associated with contamination by Salmonella enterica. Salmonellosis is an invasive disease that greatly affects highly vulnerable populations (children, the elderly and immunocompromised), causing the need for hospitalization and sometimes death. Worldwide, it is estimated that annually there are more than 94 million people affected by gastroenteritis caused by the intake of poultry contaminated with Salmonella, as well as more than 155,000 deaths. However, the origins of this strain: Salmonella enterica and others with a greater pathogenic scope are closely influenced by the control of two strains with little action in the human population: S. polloroum and S. gallinarum. The near disappearance of these two serovars prompted the colonization of strains more resistant to antibiotics and more harmful to humans.
