    Non-Typhoidal Salmonella species and Escherichia coli as Proxy Indicators of Environmental Contamination: Coliform Count and Isolation in Kilteawlaelo Health and Demographic Survey Site of Tigray Region, Ethiopia
    (Mekelle University, 2023-11-28) Goitom Eyasu
    Fecal-oral pathogens are transmitted from feces to new hosts through environmentally mediated pathways. Poor management of animal faeces and limited understanding of zoonotic pathogens from manure are common problems in Ethiopia. Animal feces have been assumed as less hazardous to human health and are neglected in the ongoing global water, sanitation, and hygiene (WaSH) program. This study aimed to determine counts of coliform and E. coli counts from faeces, hand plates, Boot socks, and drinking water; and isolate non-typhoidal salmonella species from the above sample types with the goal of providing biological for inclusion of animal faeces management in WaSH. A crosssectional study was carried out in 2020 and 2023 in randomly selected livestock owning 106 households living in the Kilteawlaelo Health and Demographic Survey Site (HDSS). From each household cattle feces, boot sock, hand plate, and drinking water samples were collected. The mean CFU/ml of E. coli in Boot socks (307005) was higher than that of water (47427), and feacal (18757) samples. The overall mean CFU/ml of coliforms in Boot socks (228137) was higher than in feces (14735) and water (11857). Many E. coli and coliforms were also counted from the hand plate of each household. The rate of isolation of Non typhoidal Salmonella species was 25.47% (27) from the boot sock samples, 19.8 % (21) of fecal samples, 12.3% (13) of the hand plates, and 9.4 % (10) of the water samples. This study gave evidence of fecal infectious bacteria circulating between the source and various vehicles in the study area. The recommendations forwarded were; public education and support on proper WaSH intervention, further study on virulence and genetic characteristics of the bacteria, and the existing WaSH program shall be reframed to include animals as WASH intervention (Water, Animals, Sanitation, and Hygiene)
