Abstract
MENDIOLA, JUDITH et al. Efecto de la digestión en la concentración de inmnuglobulina G en la ingesta de hembras de Boophilus microplus repletas. Rev Cubana Med Trop [online]. 1997, vol.49, n.3, pp. 161-166. ISSN 1561-3054.
In the present paper it was determined the concentration of immunoglobulin G in extracts from gut of female Boophilus microplus engorded during the first 7 days of the second stage of continual digestion by using the simple radial immunodiffusion technique. It was also measured the concentration of hemoglobin by spectrophotometric methods. The analysis of correlation between both variables made during the study was positive and significant for p < 0.05. The analysis of simple variance and the application of Duncan's test resulted in a marked reduction of the concentrations of hemoglobin in the gut from the 5th day of study, which is connected with the beginning of the active process of oviposition, and in an important decrease of the concentration of immunoglobulin from the 7th day of the study. Though there is a trend to diminish in the concentrations of both blood proteins, the proteolysis of the IgG by gut extracts could not be produced in vitro.
