MICROBIOLOGICAL PROFILE OF LOCALLY PREPARED FRESH FRUIT JUICES IN ADAMA TOWN, EAST SHOWA, ETHIOPIA

Abstract: Fresh fruits are essential components of the human diet and there is a considerable evidence of the health and nutritional benefits associated with the consumption of fresh fruits. However, during processing, contamination from raw materials, equipment or food handlers could be easily transferred to the final product of fruit juices resulting in food-borne illnesses. Thus, this study was conducted with the aim of determining the microbiological quality of fresh fruit juices prepare...

FREQUENCIES OF ABO AND RH-D BLOOD GROUP ALLELES AMONG STUDENTS OF FOUR ETHNIC GROUPS IN MECHARA SECONDARY AND PREPARATORY SCHOOL,WEST HARARGHE, OROMIA

Abstract: Frequencies of ABO and Rh-D blood groups vary worldwide and are not found in equal numbers even among different ethnic groups. Some variations may even occur within one ethnic group in different geographical areas. Therefore, this study was conducted to determine the frequencies of ABO and Rh-D blood group phenotypes, alleles and genotypes among Students of Oromo, Amhara, Argoba and Somali ethnic groups in Mechara Secondary and Preparatory School,West Hararghe, Oromia. A total of 4...

GENOTYPIC AND ALLELIC FREQUENCIES OF ABO AND Rh BLOOD GROUPS AMONG STUDENTS OF BUTAJIRA PREPARATORY SCHOOL, GURAGE ZONE, SOUTHERN NATIONS,NATIONALITIES AND PEOPLES’ REGIONAL STATE, ETHIOPIA.

Abstract: Genotypic and allelic frequencies of ABO and Rh blood group systems are known to vary worldwide geographically and from one population to another. The aim of the present study was to determine the genotypic and allelic frequencies of ABO and Rh blood group systems and to determine the predominant blood groups among Butajira Preparatory School students, Gurage zone, Southern Nations, Nationalities and Peoples’ State, Ethiopia. A total of 400 Students, with the age group 18-24 year...

ANTIMICROBIAL AND ANTIOXIDANT ACTIVITIES OF CRUDE EXTRACTS OF STINGLESS BEE HONEY AND PROPOLIS ON SOME SELECTED HUMAN BACTERIAL PATHOGENS

Abstract: Stingless bees produce honey (locally named as tazma mar) and propolis that are different from the Apis mellifera honey and propolis in terms of composition. The aim of this study was, therefore, to evaluate the antibacterial and antioxidant activities of honey and propolis from stingless bee in vitro against selected human bacterial pathogens. The crude extracts of stingless bee honey and its propolis were prepared using absolute ethanol, methanol and distilled water. Total phenol...
