Abstract The use of antibiotics as growth promotors to enhance animal production is banned in many countries around the world due to antimicrobial resistance. There is a need therefore, for new alternatives to antibiotics in medicine and veterinary medicine practices. The antibacterial activity of clove oil and some antibiotics were tested in vitro against three isolates of E. coli {1 avian pathogenic (E. coli 6.2) and 2 non-pathogenic (E. coli 6.1 and E. coli X)}, Salmonella enteritidis and Salmonella spp., by disk diffusion and minimum inhibitory concentration (MIC) methods. All bacteria tested showed intermediate susceptibility to clove oil using disk diffusion method except the non-pathogenic E.coli 6.1. The inhibition zones measured were 0mm, 12mm, 13mm, 15mm and 15mm for E. coli 6.1, E. coli 6.2, E. coli X, Salmonella enteritidis and Salmonella spp., respectively. E. coli 6.1 was resistant to Ampicillin, and Lincomycin with multi antibiotic resistance (MAR) index of 0.2. E. coli 6.2 was resistant to Ampicillin, Doxycyclin and Lincomycin with MAR index of 0.3. E. coli X was resistant to Ampicillin and Colistin with MAR index of 0.2. Salmonella enteritidis was resistant to Amoxycillin/Clavulinic acid, Ampicillin and Lincomycin with MAR index of 0.3. Salmonella spp was susceptible only to Neomycin but was resistant to 9 out of 10 antibiotics with very high MAR index of 0.9. The MICs of clove oil were 6.25mg/ml for the avian pathogenic E. coli and 3.12mg/ml for non-pathogenic E. coli and Salmonella spp. and 12.5mg/ml for Salmonella enteritidis. It is concluded that clove oil has promising antibacterial activity and more studies are needed to investigate its in vivo activity as alternative to antibiotics in poultry arabic 13 English 85

Background: Pseudomonas aeruginosa is one of the most invasive organism that causes severe tissue damage in diabetic foot ulcers. A major problem in P. aeruginosa infection because of that it is commonly exhibits a high degree of resistance to antimicrobial agents .To improve appropriate antimicrobial therapy and reduce the incidence of antibiotics resistant bacteria, information on the antibiotic susceptibility to this bacterium is urgently needed. Therefore, the aim of this study was to isolate and determinate the antimicrobial susceptibility of the P. aeruginosa in diabetic foot ulcers patients. Methods: This study was carried out over the period between June 2014 to April 2015 at Tripoli Medical Center. A total of 120 bacterial isolates were cultured onto bacteriological media such as nutrient agar, MacConkey agar and blood agar. Identification of retrieved bacterial isolates was done using standard diagnostic microbiological laboratory methods and antibiogram was determined by VITEK ® 2 compact automated system. Results: Twenty one strains of P. aeruginosa from 120 diabetic foot ulcers were detected. P. aeruginosa isolates exhibited multidrug resistance to Ampicillin, Augmenting, Cefuroxime, Cefoxitin, Cefazolin, Ceftriaxone, Trimethoprim/sulfamethzole, Piperacillin. However, all isolates of P. aeruginosa were 100 % sensitive to Imipenem. Conclusion: P. aeruginosa infections of diabetic foot ulcers patients have multi-drug resistant. Imipenem is the empirical antibiotic of the choice. Key words: Pseudomonas aeruginosa, diabetic foot ulcer, antibiotics resistance arabic 17 English 114

Background: During the last three decades there are many viral infections emerging and re-emerge with high socio-economic and public health impacts worldwide. The Coronavirus Severe Acute Respiratory Syndrome (SARS-CoV-2) emerged in China in late December 2019. Later, on 30th Jan 2020, the World Health Organization (WHO) has constituted the COVID-19 as a public health emergency of international concern (PHEIC). arabic 15 English 86
