The effect of bacterial endotoxin injection was studied in growing pullets of different ages. Commercial chicks were divided into 5 groups according to age. Bacterial endotoxins (E. coli and S. typhimurium) were injected intravenously and rectal temperature was measured over a period of 300 min. 2. The results showed no significant effect of age on the febrile response induced by bacterial endotoxins, but a slight tendency towards a reduced fever peak was observed with increasing age. The response latency also increased with age.769-774engendotoxinaginganimalanimal diseasebird diseasechickenEscherichia colifeverinjectionmicrobiologypathogenicitypathophysiologyphysiologySalmonella typhimuriumAgingAnimalChickensEndotoxinsFeverInjectionsPoultry DiseasesSupport, Non-U.S. Gov'tArtigo10.1080/00071669208417518Acesso restrito2-s2.0-00269179725713558572926669
