The Potential Amoebicidal Effect of Some Milk forms as an Inhibitor for Entamoeba histolytica Viability Isolated from Diarrhea

Abstract

Milk includes numerous compounds such as lacto-peroxidase, lactoferrin, immunoglobulin G, secretory immunoglobulin A, and Lysozymes The invasive trophozoites of E. histolytica are capable to inhabit host tissues and provoke diseases such as intestinal colitis. The objective of the study was to compare different forms of milk’s effect on E. histolytica trophopzoite by measuring protein concentration in vitro using a spectrophotometer and number of trophozoite by microscopy. For this purpose, E. histolytica trophozoites were exposed to several types of milk (human, sheep, cattle, goats, and formula) at concentrations of 6, 12, 18, and 24% for each type after 8, 16, and 24 hours of incubation. According to the findings, sheep and goat milk had lower total protein concentrations after 8 hours than other types of milk when compared to the control group. After 16 hours of incubation, raise the milk concentration to 24%   leading to a reduction in the formula milk's total protein concentration to 5g/l. after 8 and 16 hours of incubation, sheep milk and cattle have significantly lower total protein concentrations (24% vs. 8%), respectively. The action of formula and human milk is increased by 24-hour incubation. Increase the trophozoite inhibition percentage compared to metronidazole in human milk, which was followed by sheep and cattle milk with respective values of 60.9%, 56.1%, and 46.3% respectively. Human milk, goat and formula milk had the greatest inhibitory activity after incubation 24hrs. at 24%.the extent of amoebicidal activity of milk was shown to depend on incubation period and concentration of milk.
