Trace Element Levels in Naturally Infected Dogs with Giardiasis
As a well-known protozoan zoonotic giardiasis has manifested itself with various clinical findings in mammal species including human and dogs. Absorption of some essential biochemical elements required to growth has interrupted in giardiasis being tight relationship with malnutrition. Thus, the aim of the present study was to determine the serum trace element levels in dogs infected with giardiasis. For this purpose, totally 16 dogs enrolled in the study and 8 of these had diarrhoea compatible with giardia (infected group) and others were grouped into healthy. Diagnosis of giardia was performed by microscopical evaluation of cysts and supported by rapid test from faecal samples. In the infected group, copper (Cu), magnesium (Mg) and zinc (Zn) levels had significant differences to healthy control. Giardia infected dogs had a significant increase in Cu and significantly reduces in Mg and Zn levels. It was thought that unclear mechanism of decreased Zn levels might be related to elevated Cu involving enzyme systems. And also, malabsorption and diarrhoea were proposed mechanism for altered Mg levels, which could counteract by blocking of intestinal absorption. Consequently, Cu, Mg and Zn levels were affected in giardiasis and the addable of these elements to the treatment should be revealed by further studies.
