The current vaccines are based on live-attenuated Mmm strains and present problems with temperature stability, duration of immunity and adverse reactions, thus new vaccines are needed to overcome these issues.
‘We used a reverse vaccinology approach to identify 66 Mmm potential vaccine candidates. The selection and grouping of the antigens was based on the presence of specific antibodies in sera from CBPP-positive animals. The antigens were used to immunize male Boran cattle (Bos indicus) followed by a challenge with the Mmm strain Afadé.
‘Two of the groups immunized with five proteins each showed protection after the Mmm challenge (Groups A and C; P < 0.05) and in one group (Group C) Mmm could not be cultured…
