One thousand six hundred day old poults were randomly divided into four pens of 400 poults each. Twenty-five percent of the birds in pens 3 and 4 were inoculated orally, with Eschericia coli (E. coli) 0111ab. Ten percent of the poults in pen 2 were inoculated, intratracheally with 10°EIDso of Newcastle disease virus (NDV), A1.315/12 and 10 percent of the poults in pen 3 (previously exposed to E. coli 0111ab) were also inoculated with NDV. A total of 19 E. coli 0111ab recoveries, was made out of 200 birds that were exposed to E. coli in pens 3 and 4. Sampling of the liver was superior to sampling of either the caecal junction or the yolk sac in E coli recoveries. Airsacculitis was first observed in birds dying at 3 weeks of age, but the severity of lesions was maximum at 7 to 10 weeks of age. High mortality and morbidity observed in the commercial farms in epizootics of concurrent infections of E. coli and NDV, were not observed in this study.
