Identification was done microscopically, biochemically by different biochemical tests(IMVIC) and serologically. The incidence of E. coli in raw milk samples was 47%. Also, theserological identification of E. coli isolates revealed that O26 is the most predominant serogroup bypercentage of 21.3%. E. coli pose the greatest threat to human health because of its growing resistanceto antibiotics. Antimicrobial susceptibility testing (AST) was done by disc diffusion method against 10antimicrobials and the results revealed that E. coli isolates were highly resistant to amoxicillinclavulanate,ampicillin, cefotaxime and ceftazidime with percentages of 89.4%, 89.4%, 100.0% and100.0%, respectively. However, they were highly sensitive to chloramphenicol, ciprofloxacin andtetracycline with percentage of 100.0%, 100.0% and 93.6% respectively. In addition, 89.4% of E. coliisolates showed multi drug resistance (MDR). The ability of bacteria for adherence to food surfacesand biofilm formation is a source of food contamination that affect food safety and industry.

The response to powdery mildew disease was studied in a conditioned glass house and natural infection in the open field. Individual plants were scored and classified as resistant or susceptible according to a specific scale. The tested local wheat cultivars showed susceptible responses at both seedling and adult stages, while the Amigo cultivar was susceptible at seedling stage and resistant at adult stage. The F2 plants of all tested crosses were susceptible at seedling stage and resistant at the adult stage. Obtained results revealed that the inheritance of resistance is ruled by a single gene in the crosses Amigo/Sids12 and Amigo/Misr2; and by two recessive genes in Amigo/Gemmeiza 11 cross. The inheritance of resistance in F2 populations of Amigo/Sakha 95, and Amigo/Giza 171 crosses is controlled by two dominant genes, while in Amigo/Gemmeiza 12, Amigo/Sakha 94 and Amigo/Misr1 crosses is conditioned by two incompatible dominant genes.

However, the content of these compounds can differ between cultivars. The aim of the current study was to evaluate the antioxidant, antimicrobial and anti-inflammatory properties of three olive leaves cultivars (Picual, Shemlali and Tofahy) commonly cultivated in Egypt. Furthermore, determine their cytotoxicity for safety use in food applications. Three olive leaves cultivars were extracted with water and yield of extract was determined in each cultivar, the antioxidant activities, anti-inflammatory, cytotoxic and antimicrobial activity of 7 pathogenic bacteria, 1 yeast and 2 fungi species were determined. Of all the extracts tested, Picual had the highest content of each of phenolic (TPC) and flavonoid (114.79±4.19 µg GAE/mg,118.69±2.07 µg CE/g extract, respectively) and exhibited strong antioxidant potential in scavenging DPPH. Antibacterial potential method was against Escherichia coli ATCC25922, Escherichia coli BA12296,Klebsiella pneumonia ATCC12296, Salmonella spp., Staphylococcusaureus EMCC1351, Streptococcus mutans EMCC1815, Bacilluscereus EMCC1006, ClostridiumperfringensEMCC1574. Antifungal activities of: Aspergillusniger EMCC72, AspergillusparasiticusEMCC886T and Candidaalbicans EMCC15, were evaluated and the minimum inhibitory concentration (MIC) of all cultivars values for bacteria and yeast ranged from 12.5 to 100 mg/ml. The extracts from Picual, Tofahy and Shemlali of 5µg/ml had the highest anti-inflammatory effect. Cytotoxicity results indicated high safety use of the three olive leaves cultivars.
