As little is known about the blood profile of camels in Libya, this article is the first of a 4-part series describing the biochemical and haematological blood profile in Libyan camels. Part 1 of these manuscripts determines the values of enzymes, metabolites, electrolytes and haematological indices in the blood of Libyan camels, parts 2-4 evaluates the effects of breed, gender and age respectively on these values. In this study, blood samples were collected from sixty six camels of three different breeds, different ages and with both sex. The blood of the studied camels showed (i) average values of Potassium (K), Calcium (Ca), Magnesium (Mg), Phosphorus (Ph), Haemoglobin (Hb), Packed Cell Volume (PCV) and White Blood Cell (WBC) counts (ii) low values of Sodium (Na), Iron (Fe), total proteins, albumin, globulin, creatinine, cholesterol, triglycerides, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), and low serum activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and amylase (AMS) enzymes and (iii) high values of glucose, urea, Red Blood Cell (RBC) counts, Erythrocyte Sedimentation Rate (ESR) and Mean Corpuscular Haemoglobin Concentration (MCHC). The finding of this study was documented and compared with the findings of similar studies performed elsewhere. arabic 25 English 134

The objective of this study was to evaluate the effect of nisin in combination with different types of packaging on the survival of Listeria monocytogenes in ready-to-eat low-fat turkey bologna. Bologna was inoculated with L. monocytogenes exposed to 1 of 6 treatments: 3 packaging treatments (100% CO2, air, vacuum), each with and without nisin. Bologna was refrigerated and sampled 9 times over 42 d. Nisin reduced initial L. monocytogenes populations by 1.5 to 2 log cycles and 100% CO2 packaging prevented outgrowth throughout 42 d of storage, whereas non-CO2 packaging displayed a 2-log increase in population during storage. Nisin (500 IU/mL) combined with 100% CO2 was effective in reducing Listeria and preventing outgrowth on bologna over 42 d of refrigerated storage.

Peste des Petits Ruminants (PPR) is considered one of the most important transboundary animal diseases (TADs) with socio-economic impacts on national and international levels. During 2015-2016 a total of 690 serum samples were collected from unvaccinated domestic ruminants of which 555 sheep, and 135 goats representing teen provinces distributed in four Libyan branches (Green Mountain, Benghazi, West Mountain and Sabha). The sample were analysed at IZSAM, Teramo, Italy, by using competitive ELISA, IDvet innovative diagnostics (IDvet, 310 rue Louis Pasteur-34790 Grabels, France). The overall sero-prevalence rate (SPR) of PPR antibodies was estimated to be 41% (95% CL: 36% to 46%) among sheep and 39% (95% CL: 28% to 45%) among goat. A chi-square test was used to evaluate the probability of differences observed among SPR of infection. The results showed that the SPR of PPR was significantly (P= 0.015) higher in adult animals 41% (95% CL= 37%-46%) than in the young 24% (95% CL= 17%- 32%). The highest SPR 75% (95% CL= 61%-85%) was recorded in Sabha province (Southern Libya) which highlighted statistically difference (P= 0.00001). The preliminary results of the present study could be useful to better focus on specific area of Libya to improve understand and evaluate the risk factors for disease spreading and to plan disease control activities as requested by FAO/OIE (PPR Global Control and Eradication Strategy). arabic 19 English 100
