The highest amount of viral RNA, x10(10) copies/microl, in the feces was the one from the cloacal swab collected at *To whom correspondence should be addressed.

    This case study, carried out on 8 turkey farms located in the Centre and Pays de la Loire regions, aimed to show reflexion tracks about factors associated with appearance of non specific enteritis during the starter period ( d). Weekly measurements of environmental parameters, water quality, water and food consumption were made. The farming hygienic practices were also observed in order to A retrospective study was conducted to determine the occurrence of poult enteritis syndrome (PES) in Minnesota from January to December PES is an infectious intestinal disease of young turkeys between 1 day and 7 wk of age and is characterized by diarrhea, depression, and lethargy with pale intestines and/or excessively fluid cecal contents.

Transmissible enteritis, or "bluecomb", has been a major problem In the turkey Industry for many years. InPeterson and Hymas (76) stated that "Bluecomb is perhaps the greatest mystery malady of the poultry world." In this was probably still true.

Coronaviral enteritis has been identified in turkeys in the USA, Canada, Brazil, Italy, UK, and Australia.

After 7 days the birds became depressed and anorexic, had diarrhoea which in some cases was frothy, tended to huddle around a source of heat and constantly chirped.
