Abstract: Viability and survive of bifidobacteria strains under acidic environnement are the most important criteria for selection as probiotic. Twelve bifidobacterial strains isolated from calves faecal and eight from infant faecal during the milk-feeding period were tested for viability and resistance to acidity. These viability of bifidobacteria were examined at 0,7,14 and 21 days when the counts were variable, ranging between 5 to 6.5 log cfu/ml.Specific growth rate(μ) and generation time of Bifidobacterium strains were determined. Acid tolerance was determined by introducing the strains of Bifidobacterium in skimmed milk at pH=4.3 and enumerating during storage at 4°C.All strains showed ability to resist under SGF and bile salt but BC are more resistance and showed superior survival abilities and resistance to acidity than BI strains. Our result suggest that strains resistant to acidity seem to be suitable for food and biotechnological industry.

| Authors | : | Minal B Engavale || Meghshree V Deshmukh |
Abstract:Biosensors have been developed and used in a wide variety of ways like environmental monitoring of pollutants, detection of biological components in health care management etc. Fabrication of biosensors is not only a labour intensive process but also a very expensive one. The present study aims at developing a rapid, cost and labour effective, multi analytic microfluidic chip that can be used for the detection of markers responsible for any disease condition. One such marker uric acid, that is responsible for Gout a kidney disorder, was detected on the developed platform. The chip can also facilitate multi-analysis of a single sample on a miniaturized platform using flow through systems. The prepared device contains Sodium alginate beads with the entrapped Urease enzyme which detects the uric acid at Micron level. The entire device is established on small chip sized area (2 cm x 3cm) utilizing less volume of sample and reagents. The device is cost effective and rapid in its action.
Key words: Microfluidics, PDMS, Biosensor, Urease.

| Authors | : | Rasel Barua || H. M. Abdullah Al Masud || Md. Nuruddin Mahmud || Mohammad Abdul Hakim |
Abstract: Probiotics are a group of microbes that may help directly in enhancing resistance against human intestinal pathogens and in the prevention of gastrointestinal disorders. This study aimed to isolate Lactobacillus spp. from various raw goat milk samples for their probiotic properties. A total of 16 isolates were primarily screened from the collected goat milk samples. Only 3 isolates were found to exhibit remarkable inhibitory activity against multiple pathogenic bacteria. These probiotic strains were analyzed to elucidate their cultural, morphological and biochemical features, and were identified as Lactobacillus bulgaricus, Lactobacillus casei subsp. casei, and Lactobacillus helveticus.

| Title | : | Comparative Analysis of the Effectiveness of Sand Fly Traps with Different Baits |
| Country | : | Kenya |
| Authors | : | Mong'are samuel || Ng'ang'a Zipporah || Ngumbi Philip || Johnstone Ingonga || Ngure Peter |
Abstract: Sand flies are small haematophagous insects that transmit Leishmania parasites. Infection with Leishmania parasites results in diseases known as leishmaniases which can be grouped into three main forms: cutaneous, mucocutaneous and visceral leishmaniases. The CDC light trap is the standard surveillance technique used to determine sand fly densities in a given locality, although this technique has been hampered by several logistic issues. Therefore, this study sought to use host blood, urine and ripe fruits as baits in a modified trap to come up with a cheap device for sand fly surveillance. This study also aimed at identifying the sand fly species attracted to this new device.

Abstract: The pink stem borer Sesamia cretica is considered the most serious corn borer in Egypt and attacks young maize plants shortly after emergence devours the whorl leaves and may kill the growing points, causing dead hearts. Infested corn plants with S. cretica (larval stage) collected from the field and transferred to the laboratory. The larvae of S. cretica were reared on maize pieces. Then these larvae were fed on Bt corn to investigate the efficiency of Bt corn on biological aspects of 1st and 2nd larval instars and on histopathological effects on 4th instar larvae of pink corn borer S. cretica compared with non Bt corn under laboratory conditions. Results recorded that the Bt corn is more effective on 1st and 2nd instar larvae due to the larval mortality percent estimated by 100.0%. Bt corn showed highly histopathological disturbance in the epithelium of mid gut of 4th instar larvae.

Abstract: The discharge of textile azo dyes to the environment is an issue of health concern and can harm especially the aquatic ecosystem. The use of microorganisms has been reported to be effective approach for remediation. Five bacterial isolates with the capability of decolourizing textile dyes were isolated from textile effluent and identified as Bacillus thuringiensis (Isolate A2, B6), Bacillus badius (Isolate B5, B9), Bacillus aneurinolyticus (Isolate C2) by different morphological, physiological and biochemical tests. Physicochemical parameters such as temperature, pH and inoculum concentration were optimized for the decolourization process. The optimum temperature, pH and inoculum size for the decolourization of three experimental dyes (Novacron Orange FN-R, Novacron Red FN-R, Terasil Green) were found 30 to 35 °C, 7.0 to 8.0, and 10% (v/v) respectively.

Abstract: Objective: Stevens –Johnson Syndrome and toxic epidermal necrolysis are two most severe forms of acute drug reactions that are associated with significant morbidity and mortality. An expeditious identification of the offending drug is necessary for the early withdrawal as well as prevention of recurrence of such life threatening illness. The objective of our study was to identify the demography, offending agents, morbidity and mortality of SJS and TEN.
