Prevalence of myxozoans in swim bladders of carp determined by sequencing clones of non-specific myxozoan PCR products. Site numbers refer to carp culture sites in Table 1 and include sites without SBI (1, 2), sites with mild SBI (3, 4) and sites with strong SBI pathology (5, 6); pooled data from 8–17 fish per site (see Table 1); 50 clones were sequenced per site; numbers refer to percentage of clones per species; myxozoan taxa that did not represent at least 5% of clones at one of the sites were excluded.
