La salmonela reduce en un 29% la ganancia de peso en los pollos de engorde. El tratamiento con bacteriófagos de estas investigadoras colombianas baja la presencia de salmonelas entre un 70% y un 100%. (dedesign021 | Shutterstock.com)
La necesidad de suprimir el uso de antibióticos preventivos en la cría de pollos de engorde abre una gran oportunidad para alternativas de control naturales como la que propone un grupo de investigadoras colombianas a partir de virus bacteriófagos.
Pese a que su nombre da a entender que “fagocitan” o comen bacterias, en realidad los virus bacteriófagos las infectan para reproducirse dentro ellas, llegando a provocar en muchos casos su destrucción. Ese parasitismo natural microbiano, conocido hace más de un siglo y retomado en los últimos años, es la base de propuestas biotecnológicas que prometen un abanico amplio de ventajas para la agroindustria.
