Pathology of Anopheles stephensi after infection with Plasmodium berghei berghei. II. Changes in amino acid contents.
Infection with Plasmodium berghei results in the disease of a relatively high percentage of mosquitoes depending on the experimental conditions. The damage caused by the parasites may be so severe that the host dies. It can also become manifest for instance in a change in the amino acid content of the mosquito homogenate. The amino acid content of mosquitoes fed on a glucose solution, normal mouse blood, or the blood of infected mice was analysed qualitatively and quantitatively over a period of 14 days. The amino acids lysine, phenylalanine, proline, threonine, and tyrosine are always found in higher concentrations in infected mosquitoes. The content of leucine (and/or isoleucine) increased from the 6th day and glutamic acid from the 9th day compared to the controls. Lower concentrations were found for alanine, aspartic acid, glycine, and serine as compared to uninfected mosquitoes. Further investigations on this subject might help to find the causes for the susceptibility or resistance of individual mosquitoes to plasmodia.
