Expression of circulating leucocytes before, during and after myiasis by Dermatobia hominis in experimentally infected rats Expressão de leucócitos na circulação sangüínea antes, durante e após miíase por Dermatobia hominis em ratos experimentalmente infectados
Expression of circulating white blood cells was investigated in rats (Rattus norvegicus) experimentally infected with larvae of Dermatobia hominis, the human bot fly. Leucocytes were counted prior to infection (control group) as well as at 6, 10, 15, 20 and 28 days post-infection (dpi) and at 7, 15,...
