Abstract

In this work alterations were checked histopatologicas in the intestinal mucous membrane of chicks, caused by the challenge with Salmonella Enteritidis soon after a treatment with Lactobacillus spp. in first day of life. Two hundred and eighty-eight chicks were divided into six groups of 48 each (A, B, C, D, E and F), receiving treatment or not, at different moments of challenge. Statistically there were carried out analyses of linear and quadratic regression for the measures of the height of the villi. The lesions presented in the villi were necrosis, edema and congestion. The reduced length of intestinal villi (< 86.80% in the first challenge and < 88.56% in the second challenge) and the accentuated histopathological lesions (edema, congestion and necrosis), always observed after challenges with S. Enteritidis, subsequently recuperated independent of treatment with Lactobacillus spp. Little beneficial action of Lactobacillus spp. faced with Salmonella Enteritidis challenges could be observed, despite clearly defined regenerative capacity of intestinal villi after challenge with Salmonella Enteritidis independent of treatment.

KEY WORDS: Histopathology lesions, poultry, probiotic, villus.
