Agrobacterium mediated transformation of two peanut (Arachis hypogaea L.) explants using Na⁺/H⁺ antiporter gene to generate transgenies to resist salinity stress
(BRAC University, 2018-07)Peanut is one of the most popular sources of healthy addible oil. Its susceptance to various biotic and abiotic stresses is limiting crop production worldwide. Salinity is prior to them. Moreover, it is strictly monocious ... -
Analysis and comparison between the Genome of CRISPR bacteriophages
(Brac University, 2019-12)Viruses that infect bacteria are called bacteriophages or shortened as phages. Like all viruses, Phages are absolute parasites, although carry all the information to direct their reproduction in an appropriate host, they ... -
Analysis of enteric pathogenicity of multidrug-resistant Pseudomonas spp. isolated from commercial UHT milk
(2018-09)Pseudomonas is a kind of bacteria that has the ability to develop resistance to antibiotics rather rapidly over several generations. This resistance present in some strains makes Pseudomonas a very difficult to treat once ... -
Analysis of factors influencing successful Agrobacterium-mediated genetic transformation in two Bangladeshi peanut (Arachis hypogaea L.) varieties BINA Chinabadam-2 and BINA Chinabadam-6 using embryonic leaflet explant
(BRAC University, 2014-03)Peanut (Arachis hypogaea L.) is an important crop both for its nutritional value and for its oil content in the seeds. But this economically important crop is susceptible to both biotic and abiotic factors that hamper its ... -
Analysis of factors influencing successful Agrobacterium-mediated genetic transformation in two different explants of peanut (Arachis hypogaea L.) variety BINA Chinabadam-2
(BRAC University, 2014-03)Peanut (Arachis hypogaea L.) is a nutritious oil-seed crop. It has low productivity due to its susceptibility towards many biotic and abiotic factors. It has incompatibility towards conventional breeding techniques, thus ... -
Analysis of Vaginal Candidiasis Prevalence among Bangladeshi women in relation to menstrual hygiene and other risk factors: A cross-sectional study
(Brac University, 2022-09)Vaginal candidiasis, which is an infection of the female reproductive system, continues to be a leading risk factor of morbidity, which negatively impact the physical and mental health of women worldwide. As the second ... -
Anti-bacterial effect of essential oil extracted from homegrown Origanum vulgare L and Azadirachta indica tree on pathogenic bacteria
(Brac University, 2022-10)Antibiotic resistance has been on the rise for many years now. Multidrug resistance patterns in Gramnegative and Gram-positive bacterial strains are difficult to cure and might even be untreatable with conventional ... -
The antibacterial activities of Peppermint oil, Mustard oil and Clove oil on Klebsiella pneumonia, Acinetobacter baumannii, and Pseudomonas taetrolens
(Brac University, 2022-03)Bacteria are getting highly resistant to antibiotics throughout the time and are getting harder to treat. This project focused on up to which percentage an essential oil can inhibit a multi-drug resistant pathogen, and ... -
Antibiogram patterns of staphylococcus aureus obtained from packaged meat, milk and milk products, fruits and vegetables of various supermarkets in Dhaka city
(BRAC University, 2017-06)Staphylococcus aureus is the third most common food borne pathogen in the world. It is highly virulent and produces 20 different types of enterotoxins and it is recently being noticed that Staphylococcus aureus isolated ... -
Antibiotic resistance in commercially available probiotics in Bangladesh
(Brac University, 2022-04)“Probiotic” can be defined as live microorganism with the ability to promote health befits in the host body when consumed in adequate amount. It is well known that probiotics improve intestinal health, boost immune ... -
Antimicrobial activities of Aloe vera leaf and clove extracts, their comparison with commercial antibiotics and molecular analysis of genes involved with multidrug resistance in bacteria
(BRAC University, 2017-06)The need for new, potent antimicrobial agents from natural sources is increasing because of the growing cases of multidrug resistance in clinically relevant organisms. The purpose of this study was to investigate in vitro ... -
Antimicrobial activities of lactoferrin extracted from commercially available milk samples
(BRAC University, 2017-08)Lactoferrin, an iron-binding glycoprotein with multifunctional properties is crucial to strengthening the immune system and also useful for commercial applications. The protein’s iron-binding capacity makes it undoubtedly ... -
Antimicrobial activities of Terminalia chebula, Terminalia arjuna and Swertia chirayita against multidrug resistant Pseudmonas aeruginosa and comparison of their activities with locally available antibiotics.
(BRAC University, 2017-10)The continuous emergence of resistant bacteria is endangering the efficacy of antibiotics across the globe. The antibiotic resistance crisis has been occurring due to the overuse and misuse of these medications. However, ... -
Antimicrobial activity of lactic acid bacteria against pathogens causing food borne diseases
(BRAC University, 2016-08)Food borne diseases are quite prevalent in the current situation of the world. Adulteration and contamination of food lead to occurrence of several food borne diseases, which can be fatal, especially for infants. Moreover, ... -
Are the lakes and rivers in Dhaka city safe for recreational water activities?
