Modifications hématologiques chez des poulettes infectées par <em>Salmonella</em> Paratyphi A

Salmonella species are capable of producing changes in the white and red blood cells of the affected animals. For instance, pigeons infected with Salmonella typhimurium showed leukocytosis within the first twenty-one days post-infection (7). A group of cockerels injected with 50 mg/kg body weight of Salmonella gallinarum endotoxin intravenously produced severe hypochromic anemia, leukocytosis and increased phagocytic activity of leukocytes (10). In another investigation Asheg et al. (2) experimentally infected a set of day-old chicks orally with 2 x 102 cfu/mL of Salmonella enteritidis PT4 and recorded a significant (P < 0.05) increase in the peripheral lymphocyte count on day 21 post-infection (p.i.), while a significant increase was observed on day 27 p.i. for chicken orally infected with 2 x 108 cfu/mL.
