This study was aimed to investigate the prevalence toxigenic fungi and mycotoxines, a total no. of 90 samples representing various types of animal and poultry feedstuffs were collected from different localities in Egypt; Alexandria, Beheira, New Valley, Assiut and Cairo, The results showed that 78 with a percentage of 86.7% of samples were contaminated with different fungal species, the fungal load was ranged from 0.4 to 12 x 10³ cfu/gram among different samples, Aspergillus was the most common genus being isolated from all mycologically positive samples with total count of 101900 colonies per gram matching 83.84% of total fungal population. 16 species of Aspergillus; which A. flavus and A. niger were the most common colonizing 72.2% and 56.6% of samples matching 15.8% and 41.7% of total fungal count. Penicillium appeared in 50% of samples accounting for 13.1% of total fungal population. Also in the present study 13 feedstuff samples were analyzed for mycotoxin contamination. These samples were mycologically positive yielding low (40-600 cfu/g) or high number of fungal colonies (1280-4920 cfu/g). A. flavus and A. niger were the dominant species in these samples, aflatoxin B1 at level of 0.851 and 1.363 ug/kg were detected in 2 samples; respectively. Aflatoxin B2 at a level of 0.479 ug/kg was also detected in 1 sample. Levels of Aflatoxins in the positive samples (AFB1 and AFB2) are below the recommended limit for animal feedstuff ingredients for beef cattle (20 ug/kg). From previously mentioned data, it was clear that feedstaffs of animal and poultry in Egypt represented hazardous source of toxigenic fungi which harm animal and poultry health, decrease their production, and could be serious sources of human illness, so regular screening in animal and poultry feedstaffs in Egypt is a good practice in order to control and overcome their presence and dangers.

Keynote: Phytochemical Analysis and Neuroprotective activity of PEDALIUM MUREX LINN Leaves against Bacterial Cell Wall Content LIPOPOLYSACCHARIDE-Induced Endotoxemia
Time : 10:30
Mrs. Gomathi Swaminathan, M.Pharm., is perusing part-time Ph.D in The Tamil Nadu Dr. M.G.R Medical University, Chennai, Tamilnadu, India and is a full-time faculty of J. K. K. Nattraja College of Pharmacy, Kumarapalayam, Tamilnadu, India. Her field of doctoral and research work is primarily on herbal phytoconstituents and medicines for neurodegenerative disorders. She has published 20 research articles in various national and international journals and has received many best poster and oral presentation awards, young scientist award in various national and international conferences.
Neurodegenerative diseases (ND) are threatening worldwide. Huge number of behavioural changes are associated with ND such as depression, anxiety, memory loss, stress and so on. Effective drugs need to cure the ND from nature. In this present study, we had evaluated the phytochemical analysis and neuroprotective activity of Pedalium murex Linn (PM) leaves against bacterial cell wall content Lipopolysaccharide (LPS)-induced endotoxemia in rats. Two compounds were isolated from 90% v/v of ethanol extract of Pedalium murex Linn (EEPM) named as PM I, PM II. Spectral data of isolated compounds strongly suggested that PM I showed the structural similarities with 4´, 5, 7- trihydroxy flavone may be Apigenin and PM II showed the structural similarities with 3,5,7-Trihydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one which may have the presence of kaempferol. The data of our present study revealed that LPS significantly decreases the food, water intake and body mass which was recovered EEPM treated rats. EEPM attenuated or completely abolished the symptoms of depression and anxiety. Antioxidant enzymes includes SOD, CAT, GR, GPX levels were decreased in LPS-treated rats, which was recovered by EEPM treated rats. Histopathological results also support the neuroprotective effect of EEPM against LPS-induced neurodegeneration. We may conclude that EEPM may be a potential candidate for LPS-induced brain damage which may be attributed to the presence of potent antioxidants in EEPM
