内容記述
Diarrheagenic Escherichia coli (E. coli) in suckling rabbit causes collibacillosis, which is characterized by sever yellow diarrhea, poor growth and high mortalities. This study was undertaken to investigate the prevalence of diarrheagenic E. coli in suckling rabbits in Egypt. Additionally, expression of some virulence-associated genes in the isolated E. coli serotypes were examined using the polymerase chain reaction. Finally, antibiogram of the identified E. coli serotypes was also investigated. E. coli could be isolated from 40% of the examined samples collected from diseased suckling rabbits having yellowish diarrhea. Cecum harbored the highest incidence of E. coli followed by stomach, liver, heart and spleen. Four serogroups could be identified including E. coli O109:H2, O15:H-, O103:H2 and O8:H-. Isolated pathogenic E. coli serogroups harbored different virulent factors responsible for diarrhea. Additionally, isolated E. coli serogroups showed marked low sensitivity or even resistance to the most common used antibiotics in Egypt.
