The main objective of this study was to assess glomerular filtration rate (GFR) in the camels (Camelus dromedarius) under free water access and dehydration conditions (after a 34 days-period of water deprivation) using plasma exogenous creatinine clearance without urine collection. Trials were carried out on six nonpregnant, non-lactating and healthy female camels. Creatinine was administered as an IV bolus at a dose of 16 mg/kg body weight. Blood samples were collected at predetermined times over 24 h post-injection. Plasma creatinine concentration was analysed using Jaffé method. Creatinine clearance was calculated by pharmacokinetic analysis using a non-compartmental approach. Water deprivation induced a significant 15%- decrease in body weight but did not affect haematocrit and total plasma proteins. Mean corpuscular volume increased and red blood cells number decreased in dehydrated conditions. Dehydration produced a significant 30%-increase in plasma creatinine and mean residence time and a significant 20%-decrease in GFR. In conclusion, water deprivation decreased glomerular filtration and plasma exogenous creatinine clearance test could be used as a practical method for GFR assessment in dromedary camel in field conditions.

To fight animal rabies, Moroccan veterinary authorities organize annual dog mass vaccination campaigns using Rabivac vaccine, an inactivated adjuvanted cell culture veterinary rabies vaccine. Two experiments were undertaken to assess the efficacy and immunogenicity of Rabivac.The first experiment involved 13 caged dogs (8 vaccinated and 5 negative controls). Dogs were bled at day 0 (D0) and at days D7, D14, D21, D28, D35, D49, D56, D64, D70, D77, D84, D91, D98, D105, D112, and D119 post-vaccination. At D121, a virulent challenge was performed. After 70 days monitoring period, seven out of eight vaccinated dogs survived the challenge (one dog succumbed to a mesenteric torsion accident) and four out of five controls succumbed. All vaccinated dogs seroconverted and the control dogs remained negative. The second experiment consisted in a field study involving 919 owned dogs randomly selected in eight Moroccan districts located in different parts of the country. The dogs were identified and vaccinated by the parenteral route and bled on the vaccination day (D0) and on D30.Ninety-two percent of dogs developed a positive rabies virus neutralizing antibody response to vaccination and 24% were positive at D0, suggesting that dogs were previously vaccinated. The increase in rabies antibody titers was highly significant in all districts. No significant difference seemed occurring between the geographical status (rural, semiurban, or urban) of the districts on the results obtained.Rabivac is efficacious both in experimental and field conditions. This supports its use in dog mass vaccination campaigns.

In Morocco, the tomato borer T. absoluta was found for the first time in April 2008 in the region of Nador, and then spread rapidly in all tomato producing regions. Since this finding, efforts have been made by professional and technical departments of the Ministry of Agriculture and Fisheries to deal with this pest. The action plan (2008-2009) was based on monitoring, control engineering approaches as part of an IPM program, education, supervision and production of information materials and training. To encourage farmers to adopt integrated pest management approach against this pest, grants have been established by the Ministry of Agriculture and Fisheries for the acquisition of the insect-proof screens and pheromones capsules for mass trapping. And, The ONSSA authorized new pesticides to fight against T. absoluta in cultures of tomato and potato. This strategy has been evaluated following which, an action plan for 2010-2011 was defined. This action plan has the same basis as the previous campaign while emphasizing pest monitoring in tomato crops in open fields, strengthening the education program and supervision for farmers and launching a program to monitor pesticide residues in tomatoes. During the 2010-2011 campaign, the tomato borer remained under control. © 2012 The Authors. Journal compilation © 2012 OEPP/EPPO.
