Which stages of Plasmodium are likely to be found in the stomach of a female Anopheles. Which has just taken a blood meal from a patient of malaria?
1 Merozoites, trophozoites and gametocytes
2 Sporozoites, trophozoites and gametes
3 Merozoites, gametocytes and zygotes
4 Gametocytes, ookinetes and gametes
Explanation:
Plasmodium is known to infect the red blood cells in mammals like humans, birds, reptile etc. - It causes a infectious disease known as malaria and transmitted by female anopheles. - The merozoites infect red blood cells. The ring stage trophozoites mature into schizonts, which rupture releasing merozoites. Some parasites differentiate into sexual erythrocytic stages such that gametocytes.

Which is the characteristic feature of ookinete?
1 It have microtubules
2 It have more mitochondria and ribosomes
3 It have contractile fibres
4 It is non-motile
Explanation:
An ookinete is the motile zygote that forms when the microgamete (derived from the male gametocyte) fertilizes the macrogamete (derived from the female gametocyte) during the sexual reproduction of certain sporozoans such as Plasmodium. - The ookinete penetrates through the epithelial cells lining the midgut of the mosquito where it differentiates in to an oocyst.

What conditions are optimum for activation of gametogenesis in Plasmodium in stomach/ alimentary canal of femal Anopheles?
1 High temperature
2 Presence of enzymes
3 Less temperature
4 Blood in stomach
Explanation:
Both Anopheles and Plasmodium are sensitive to temperature because mosquitoes are ectotherms, each life stage is dependent on temperature in the development and mortality rate. - Temperature is particularly critical, for example, at temperatures below $20^{\circ} \mathrm{C}$ Plasmodium falciparum cannot complete its growth cycle in the Anopheles mosquito and thus can not be transmitted.

Incubation period of Plasmodium falciparum is:
1 10 days
2 12 days
3 16 days
4 28 days
Explanation:
The incubation period of Plasmodium falciparum is the shortest period compared with all the other Plasmodium species. - Incubation periods of 9-14 days for the immune and 6-14 days for the non-immune have been reported for Plasmodium falciparum.
