The Bacteria and Parasite Patterns in Flies Do Not Associate With the Prevalence of Fly Vector-Borne Diseases at the Dairy Farm

Abstract

The fly is the vector of several intestinal diseases. It can transmit pathogenic agents, including bacteria such as Salmonella, Shigella, Escherichia coli, Staphylococcus, as well as parasites such as Entamoeba histolytica, Balantidium coli and Giardia lamblia. The dairy farm is one of the sites where the flies are commonly found. This study analyzed the association of the bacteria and parasites pattern in flies and the prevalence of fly vector-borne diseases at the dairy farm. The fly samples were collected at the Rembangan Dairy Farm, and the bacteria and parasite were identified at the Laboratory of Microbiology and Parasitology, Faculty of Medicine, University of Jember. The prevalence data of fly vector-borne diseases were collected from the Public Health Centers around the study site as the secondary data. Bacteria identification using selective media found only E. coli, but no parasite was observed in the samples. We found diarrhea, typhoid, and dysentery as fly vectorborne diseases. Statistical analysis using chi-square resulted in p=0.072, meaning no significant association of the bacteria and parasites pattern in flies and the prevalence of fly vector-borne diseases at the dairy farm. The use of secondary data for disease prevalence could be a limitation of the study. Further study by directly examines the samples from fly vector-borne diseases is needed to draw a definite conclusion
