Application of AID to the calcium-regulated protein phosphatase, calcineurin, revealed functions in host and vector stages of parasite development.
One isolate from such an area in Zambia, T. parva Chitongo, was compared for virulence with T. parva Muguga, isolated from an area exhibiting a continuous presence of all vector stages in East Africa.
In addition, our study demonstrates the feasibility of using genetically modified P. falciparum to study host-parasite interactions in the vector stages of development.
Among them, differentiation in the insect vector stages [20] and inside the mammalian cell [9], as well as energy metabolism [19], seem to be of relevance.
Markers of apoptosis have been described in both the vertebrate and vector stages of the malaria parasite [14] [17] although, as discussed by Arambage and colleagues [18], conflicting results have emerged from different laboratories, particularly regarding apoptosis in erythrocytic stages.
Density of immature vector stages at breeding sites, as measured by larval dipping (Silver 2008).
Evidence of an effect of larvivorous fish on the density of immature vector stages in water bodies was variable.
Larvivorous fish may cause a reduction in the percentage of breeding sites positive for immature vector stages (five studies, unpooled data, low quality evidence).
However, this stockpiling of heme may be related to a lack of heme availability in the upcoming insect vector stages of parasite development.
These substrates are so important that they are necessary for the culture of vector stages in T. cruzi and can ensure survival during starvation conditions [ 11, 12].
