Detection and identification of cyclops in well’s water, Jabal Awliya locality, Khartoum, Sudan 2021

Background: Dracunculus medinensis or "Guinea-worm" is the parasitic worm that causes Dracunculiasis disease. The Cyclops (Meso and Micro Cyclops), which is only spread through drinking from water sources in endemic areas, carries this worm. This study aimed to detect and identify Cyclops in wells water, Jabal Awliya locality Khartoum state, Sudan 2021 Methods: This is a cross sectional study held in Jabal Awliya locality which is located in Khartoum state Sudan from 2021-2022. The locality is one of the seven localities in the state which is considered as the main gate for the refugees from South Sudan, Chad and Ethiopia where Dracunculus medinensis has not been eradicated yet. The population is 274,321. Results: A total of 264 samples were collected,132 from well’s water and 132 from post wells water sources. Well’s water contamination with cyclops was found to be 2.4% while post well’s contamination was found to be 8.9%. The species reported by microscopy are: Afrocyclops, Mesocyclops and Microcyclops. Significant statistical difference between well’s and post well’s contamination was found (p-value 0.02). Conclusions: In conclusion, it is apparent that well’s water as well as dam water are contaminated with copepods (Afro-, Meso- and Microcyclops). Hence Residents in the research regions are at hazard for Dracunculus infection whenever larvae make their way to the water sources since mesocyclops and microcyclops are recognized Guinea worm vectors. Since no apparent water treatment system has been found in the areas under study, it is crucial that water sources in this area be treated before consumption in order to reduce the risk of illness.  Awareness by the worm as well as the disease should be raised in order to ensure that the larvae from the hosts will not be carried to the wells.
