Serological variation among Polish isolates of Yersinia ruckeri

tom 54

nr 3

One hundred and twenty-six isolates of Yersinia ruckeri originating from different species of fish were collected: 122 from rainbow trout (Oncorhynchus mykiss; Walbaum), three from pike (Esox lucius L.), and one from carp (Cyprinus carpio L.). The O- serotyping of the isolates were carried out for the first time in Poland by microplate agglutination assays according to the Davies procedure. Three O-serotypes were determined: O1, O5, and O7. Serotypes O2 and O6 have not been recognised. Almost all isolates were represented by serotype O1, which originated only from rainbow trout showing classical clinical signs of enteric redmouth disease. The strains representing serotype O5 were only collected from pike and serotype O7 from carp and rainbow trout showing no clinical signs of the diseases.

A panel of four monoclonal antibodies (MAbs) was used to study the immunological profile of Rice yellow mottle virus (RYMV) genus Sobemovirus. Serological profiles of 35 representative isolates of RYMV from Borno, Gombe, Kaduna, Kano, Niger, Sokoto and Zamfara states in Northern Nigeria. All the RYMV isolates were classified into three major serogroups (SG1, SG2 and SG3) and further separated into six subgroups (Sg1a, Sg1b, Sg2a, Sg2b, Sg3a and Sg3b). The results demonstrate a significant serological variability among RYMV isolates in Northern Nigeria. The hierarchical analysis of the serological profiles data revealed high viral load in Kano, Kaduna and Gombe states, these show they are suitable locations for strategic RYMV diagnostic and field epidemiological studies.
