Protein profiles of bacteriophages of the family Myoviridae-like induced on M. haemolytica.


ABSTRACT: The aim of study was to isolate, characterize and analyse the protein profiles of Myoviridae-like bacteriophages obtained from M. haemolytica using MALDI TOF mass spectrometry. The material consisted of the M. haemolytica reference strain ATCC® BAA410, reference serotypes A1, A2, A5, A6, A7, A9, and A11, and wild-type isolates of serotype A1. Bacteriophage morphology was examined with a transmission electron microscope. The proteins were separated in SDS-PAGE and two-dimensional electrophoresis and characterized by MALDI-TOF. Among the phages obtained, seven were specific for strains A1, A2, A5, A6, A7 and 25, and PHL-1 was specific for the BAA410 strain. The protein profiles for the phages were very similar to one another, but differed from the reference phage in that they lacked protein fractions with molecular weights of 22.9, 56.3 and 73.1 kDa. 2D electrophoresis revealed significant differences in the size of proteins and their localization in the pH gradient. The most similar profiles were observed in phages specific for strains BAA-410 and A6. In all profiles two main spots were observed in the molecular weight range from 44 to 70 kDa at pH?
