Un concatémero es una molécula de ADN que contiene copias múltiples de una misma los concatémeros son el producto de la replicación en círculo rodante y se los puede observar en la etapa final de la infección de bacterias por fagos. Un virus es un microorganismo que se reproduce dentro de las células de huéspedes vivientes .. Los bacteriófagos son virus que infectan bacterias. Hay más. La clasificación de virus es el proceso de nombrar los virus y colocarlos en un sistema de La definición de los órdenes es muy reciente y ha sido deliberadamente lento; y por hoy, solo tres han Orden Caudovirales ( bacteriófagos en cola).

Phage display – Revista bionatura. Display technology on filamentous phage in the search for anti-infective biological agents. The causes of antibiotic resistance are complex. The phage display technology has been used mainly to produce monoclonal antibodies MAbs and peptides directed against cancer or inflammatory disease targets.

Today, this technology is recognized as a powerful tool for selecting novel peptides and antibodies that can bind to a wide range of antigens, ranging from whole cells to proteins and lipid targets. In this review, we highlight research that exploits the phage display technology to discover new drugs against infectious diseases, with a focus on antimicrobial peptides and antibodies.

Basic and recent literature review was made, mainly focused on general aspects of phage display technology and the application in the search of new peptides or antibodies of pharmaceutical use to combat the infectious diseases transmitted by bacteria and virus. Updated information defonicion the selected topics is shown, with a guiding and practical approach aimed at researchers in the field of molecular biology to continue deepening the technology with definiciin emphasis in the applications that have been developed in Cuba.

Advances in methods of screening, manufacturing, and humanization technologies show that phage display technology can significantly contribute in the fight against clinically important pathogens.
