The copper element showed significant difference between patients and controls with lower average of concentration in seropositive patients than the control. Non-significantly difference was found for this element between females and males of both control and patient groups (p>0.05). Non-significantly difference was found in Mg, Zn and Fe levels between patients and control groups. Such results indicate the significance of additional knowledge of the mineral homeostasis and the regulatory processes during toxoplasmosis infection. T. gondii INTRODUCTION problem,etiatsl deficiency exceed 50% in developing In infection, similar to other intracellular countries and can also be seen in developed world pathogens, innate immune response is the first line (Watson , 2010). defense that is important in restricting parasite Copper is another trace elements required for many dissemination while adaptive immetunael function is creutciaall important metabolic processes, it binds to many Cu- for the suppression of parasite growth and long-term dependent enzymes like cytochrome c oxidase and defense against infection (Khan , 2019; Sasai , tyrosinase. Similar to etzianlc, copper is important for 2018). In immune-competent patients infected with maintaining and improving of immune system response toxoplasmosis, it is mostly has no signs or mild symptoms (Salman, 2014; Stafford , 2013). and provides non-specific symptoms such as enlarged Decreased concentration of these elements may affect the lymph nodes, stiff neck, painful swallowing, fever, activities of innate and adaptive immune system cells, myalgia, and abdominal pain (Waree, 2008). through decreased cell number and/or impaired their Trace elements are micronutrients which are needed in function. eStuaclh effect may trigger raised morbidity and low concentration and play important functions for mortality to microbial, viral as well as parasitic infections human body. Several trace elements (as zinc, copper, (Stafford , 2013). magnesium andetiraoln) modulate the function of the This research aims to compare the levels of certain trace immune system and effect on host susceptibility to elements in immunocompetent patients with chronic infection (Rivera , 2003). toxoplasmosis and healthy individuals. Magnesium used for many biochemical functions in the subjects: body such as synthesis of proteins , lipids and antioxidant MATERIALS AND METHODS glutathione, regulation of blood pressure and control of Sixty of both sexes Iraqi immunocompetent blood glucose level, although Mg deficiency is not patients who were seropositive in toxoplasmosis test in common, this can occur because of the low dietary intake , addition to 82 healthy individuals for control (who have alcohol abuse, or diuretic drugs using (Al-Fartusie & no toxoplasmosis), were participated in this study. These Mohssan, 2017). cases were collected during the period from September Zinc is act as important cofactor for over than three 2019 to January 2020.The patients and healthy thousand metalloenzymes and proteins such as copper/ individuals (control) have been of different geographic zinc –superoxide dismutase (SOD) and metallothionin residencies and different age groups, ranged between 23 (Weisse&t aCl arver, 2018). There is increasing evidence of -70 years old. Each participant was provided with pathogen-specific protective effects of zinc (Astiazarán informed consent. Cases have IgM positive, and cases García , 2015). used currently trace elements supplementation were Iron is important component of many proteins such as excluded. Five milliliters of blood samples were obtained hemoglobin and myoglobin which have a role in from all participations in sterile conditions.

For optimal functioning, the Calorimetrically using immune systemet anleeds important micronutrients and commercial diagnostic kits (Labkit, Spain for Mg and LTA, trace elements, including zinc, copper, magnesium and Italy for Zn, Fe and Cu), 4 trace elements were analysed iron (Stafford , 2013).Deficiency in micronutrients for their concentrations in the sera of all cases by and infectious diseases frequently occur together and has absorption spectrophotometry. complicated interactions. This combination is more observed in people living in developing countries, STATISTICAL ANALYSIS especially in rural regions (Salman, 2014).

The average Zn concentration in seropositive patients Zinc deficiency is a rising public health concern. Zinc was lower than in controls (figure 2). However, non- deficiency was reported to be due to malabsorption and significantly difference was found between patient and insufficient intake, and was associated weithalgrowth,
