Serum zinc and copper levels in relation to parasitic infestations

ABSTRACT

One hundred child in Adlia primary school at Sharkia Governorate were subjected to full history, clinical examination, stool and urine analysis for parasitic eggs and cysts. Estimation of serum zinc and copper levels using atomic absorption - spectrophotometry was done. The commonest parasitic infestation was Entamoeba histolytica [29 percent] followed by Enterobius vermicularis [16 percent], Schistosoma mansoni [13 percent] and Giardia lamblia [11 percent.] There was a significant decrease in serum zinc levels among children infested with parasites versus those who were parasites free. In Schistosoma mansoni infection there was very high significant decrease in the mean serum zinc level. The serum copper levels were higher among children infested with parasites compared to those without parasites, but this difference was not significant
