In order to determine the statute of the broiler turkey farms (n= 20) with respect to the contamination by Salmonella, three visits were paid to each livestock buildings. A batch of 10 pools of 5 droppings per breeding by visit were collected (n= 600) and analyzed. All Salmonella (n= 62) isolates were serotyped, confirmed by the presence of virulence gene (invasion) and tested for the resistance to 15 antimicrobial agents by the agar diffusion method. In parallel, an analytical study was carried out to investigate risks factors of Salmonella contamination in these farms. The rate...

Prevalence, diversity and antimicrobial resistance of Salmonella enterica and Pseudomonas aeruginosa isolates from spring Water in a rural area of northwestern Morocco. Biodiversitas 22: 1363-1370. The persistence and diversity of serotypes belonging to pathogens in environmental waters including surface and groundwater have been widely documented and that the aquatic environment represents a relatively stable environment for these microorganisms. Study was carried out on the prevalence, diversity, and antibiotic resistance of Salmonella enterica and Pseudomonas aeruginosa isolates taken from 102 samples of spring water in a rural region of Northwestern Morocco (Rabat-Sale-Zemour-Zaer) collected for two seasonal campaigns between March 2010 and June 2011. The search and identification of S. enterica and P. aeruginosa were carried out according to ISO 19250 and ISO 16266 methods respectively. The serotyping of S. enteri...

This network consists of three groups of water areas and covers almost the entire study site. With the help of the method of Piper diagram, the waters of different origins are easily differentiated

Also come a rise demand which results from the demographic growth, of the improvement of the living conditions, the exploitation of spring water, the development of various industries and the extension of irrigation. This book,therefore, provides the hydro-biological analysis of water sources of Morocco's Rabat region.In order to highlight an assessment of physicochemical, metallic and bacteriological quality of the spring water in this area.Part of this work iS devoted to followed the quality of spring waters physico-chemical, metallic and bacteriological parametres)and other part devoted the anthropic activities and factors which can deteriorate these water resources.The various methods used in this work should help to make the light on this type...

At the level of Morocco, the waste produced by hospitals has risen sharply in the regions most affected by the virus, such as the Rabat-Sale-Kenitra region (15.05% of recorded cases). The objective of this study is to perform a descriptive statistical analysis and to evaluate the generation rates of MPW generated during the treatment of the coronavirus pandemic, with reference to a large health care hospital in the region, in order to enable decision-makers to adopt responses in terms of regular and continuous management of MPW. The Moulay Abdellah hospital in Sale has a bedding capacity allocated to the COVID-19 patient of 110 beds with a Average Occupation Rate (AOR) of 100% and an average production of 13tons per month. The study showed that the averag...
