Phenotyping of E. coli serotypes associated to oedema disease

Table 4 Serotypes of E. coli demonstrated in faecal samples collected from apparently healthy weaners in a herd severely affected by oedema disease caused by E. coli serotype O139.

Serotype	O139	O8	O98	O149	O157	O?
*Samples*
35	2	3	4	4	1	21
(%)	5.7%	8.6%	11.4%	11.4%	2.9%	60.0%

The two isolates of E. coli O139 were obtained from two survivors in a litter affected by oedema disease. These isolates belonged to the same BPT that previously had been demonstrated in pigs from the herd affected by oedema disease. The diagnostic panel included 18 of the most common pathogenic serotypes in the country
