About this work

Description

A detailed cinematographic record of the classic laboratory technique for dissecting a mosquito to detect malaria parasites. The film describes the oocyst and sporozoite phases of the life-cycle of the malaria parasite within the mosquito before demonstrating how the mosquito's salivary glands are pressed out and prepared for examination so that sporozoites can be identified, and the way in which the stomach is removed and the oocysts are detected. 2 segments.

Contents

Segment 1 Opening credits. There is a shot of a female anopheles atroparvus species of mosquito feeding on blood from a human arm, the means whereby malaria is transferred. Diagrams show the anatomy of the mosquito and the lifecycle of the malaria parasite. Intertitle: Technique of Dissection: 1) removal of salivary glands. The technique is shown. Special dissection needles are shown; the mosquito is killed and made ready for dissection. Time start: 00:00:00:00 Time end:00:04:35:02 Length: 00:04:35:02
Segment 2 The salivary glands are pressed out into a drop of saline; the sporozoitesa re-examined under the microscope. 2) removal of stomach. This is done on a slide and oocystes are seen. Commentary explains the oocyst rate and sporozoite - the latter is the strongest indicator of field malaria. Time start: 00:04:35:02 Time end: 00:09:27:24 Length: 00:04:52:22
