Current Research Projects & Grants
- “KIP Project: The Perception of Students in Rural Schools towards Women”
The aim of this study is to explore the perception of students enrolled in Lebanese rural schools towards the role of women in their communities and the perceptions of women themselves about their status in these communities.
- “Freshwater Diversity Identification for Europe – FREDIE”
The project targets biological research on freshwater fishes. It is funded by the Leibniz Association Joint Initiative for Research and Innovation, Germany.
- “Geographic, ecological and behavioral studies of the Lebanon mountain viper Montivipera bornmuelleri (Werner, 1898)”
Montivipera bornmuelleri is an endemic viper species described for the first time in Lebanon by Werner (1898). It is found mostly in Lebanese mountains from 1800 meters and higher with some records of this species in Syria. This species has been red-listed by the International Union for the Conservation of Nature (IUCN, 2014) as endangered species (EN) due to its limited geographic range, which is estimated to be less than 20,000 km2.
Previous studies were conducted earlier on this snake species in Sannine and Makmel Mountains between 1800 and 2200 m altitude. The habitat differences and associated reptiles species between Sannine and Makmel Mountains have raised some questions that require a more detailed study of the habitat structures in the two localities and future comparisons with habitats in the new regions to be studied.
Further work is required in this proposed study to investigate other geographic localities (e.g. Mount Hermon and the Anti-Lebanon). The ecological study of Montivipera bornmuelleri will be expanded to include a survey of new geographic locations, detailed examination of its habitat structure, spatial behavior and home range using telemetry, diet, defensive, predatory and territorial behaviors and their implications for the interaction with the local human community.
This study is carried out by Professor Souad Hraoui-Bloquet (Professor, Faculty of Sciences II, Lebanese University), Dr. Nisreen Alwan and Dr. Riyad Sadek (Assistant Professor, Biology Department, American University of Beirut).
- “A review of Brucellosis in dairy-based food products”
The consumption of dairy-based foods may play an important role in the transmission of various food-borne diseases. Among those diseases is brucellosis, which is considered by the Food and Agriculture Organization (FAO), the World Health Organization (WHO) and the Office International des Epizooties (OIE), as one of the most wide-spread zoonotic diseases of domestic and wild animals throughout the world. Brucellosis is a “re-emerging” disease leading to substantial economic loss as well as considerable human morbidity. It is a disease caused by several species of the genus Brucella. Brucella is a genus of Gram-negative, non-motile, non-spore forming, aerobic chemo-organotrophic, catalase-positive bacteria. Brucella organisms are coccobacilli and occur typically as intracellular parasites. Brucella is a fastidious organism, which needs specific requirements for its growth.
Based on host preferences and pathogenicity, the genus Brucella has been divided into six species: B. abortus, B. canis, B. melitensis, B. neotomae, B. ovis and B. suis. Out of these six species, only B. abortus and B. melitensis are the major pathogenic species in human beings and animals. Brucellosis can be transmitted to human beings by direct contact with materials contaminated with the organism, consumption of unpasteurized milk and milk products, and inhalation of infectious aerosols, especially by workers in abattoirs and microbiology laboratories. The most common signs and symptoms of this disease are undulant fever, weakness, chills, headache, depression and weight loss, which can persist from days to years.
Recent advances in taxonomy, isolation methods, bacterial typing, and molecular and cell biology have extended our knowledge. This review offers an up-to-date introduction to the organism with a description of virulence determinants. A detailed account of diagnosis, epidemiology and outbreaks, transmission and clinical symptoms, treatment and control of Brucellosis will be provided.
