CAFETERIA DIET CONTAINING 16% FAT, CAUSES LITTLE VARIATION IN PARASITEMIA AND MORTALITY OF FEMALES C57BL / 6 MICE WITH CEREBRAL MALARIA CHRISTIANE LIMA MACHADO(IC)( 1 ), ANA CRISTINA M.

Introduction: The obesity in humans is increasing every year due to lifestyle changes. Obesity is associated with insulin resistance, dyslipidemia, steatosis hepatitis and cardiovascular diseases. Several obesity models have been used to research the relationship between obesity and diseases. One model is used to diet-induced obesity (DIO), which is developed after feeding mice with highfat diet (HF diet). It is very similar to human obesity that is result of food overconsumption and sedentary lifestyle. The relation among obesity and diabetes or cardiac diseases is well established, but, the role of obesity in the course of infectious diseases is still poorly understood. Malaria is a tropical disease that causes lots of deaths worldwide. Thus, the aim of this work was to establish a model of DIO and to evaluate whether the influences of DIO in parasitemia and mortality of female mice during the course of cerebral malaria infection in obese mice. Methodos and Results: C57BL/6 female mice, 4-6 weeks age, were given ad libitum water and standard chow high-fat diet (HF) that contained 16% of fat. Food consumption and body weight were monitored every week. Obesity was proved by Lee Index and measurement of perigonadal fat pad weight. After 16 weeks, control C57BL/6 female mice, and HF group were infected with Plasmodium berghei-ANKA (5 x 10 6 iRBCs/mL). Parasitemia was evaluated daily after infection in all of groups by collecting a small fraction of mice‟s tail blood and spreading it in a slide and stained with Giemsa solution. The percentage of infected red blood cells (iRBCs) was evaluated in comparison to total RBCs. Mortality curve was elaborated according to the number of mice dying from infection in each day after the inoculation of Pb-ANKA. Female C57BL/6 DIO mice showed the significant fat accumulation. The parasitemia and the mortality was not significant between obese and control, but we
observed a tendency to lower parasitemia in obese and higher mortality rate when compared to control ones. Conclusions: We conclude that this DIO model is able to induce obesity in females C57BL / 6, but slightly alters the course of infection.Experiments using diet with higher amounts of lipids are being evaluated to see if the course of infection is changed significantly Financial support: FAPEMIG
