“…There are two types of bacteriophages relative to the host -specific, i.e., those infecting a limited number of strains of one type of bacteria, and polyvalent ones. Polyvalent phages are able to infect not only certain strains of one species of bacteria, but also different species and/or genera and groups of bacteria (Sovinska, Korotyeyeva, & Andriychuk, 2017;Sovinska, Petrenko, & Andriychuk, 2015). This ability of certain bacteriophages can be the key in combating dangerous bacterial pathogens in various areas of our lives, including medicine, agriculture and the food industry (Drulis-Kawa, Majkowska-Skrobek, Maciejewska, 2015; Halawa, 2023;Faidiuk, 2015).…”
