(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?
(BRAC Univeristy, 2018-07)Unplanned urbanization can lead to contamination of the surface waters with industrial and fecal pollutants. Fecal organisms can cause a number of diseases to humans in case of skin contact or accidental ingestion. The ... -
Are the lakes and rivers of Dhaka city safe for water-based recreation? A case study of Salmonella spp.
(Brac University, 2019-04)Unplanned urbanization, defective sewerage system and lack of public concern can result in contamination of surface water bodies. As these water bodies are a major part of diurnal and recreational activities, contamination ... -
Are the lakes and rivers of Dhaka city safe for water-based recreation? A case study of Salmonella spp.
(Brac University, 2018-11)Over the past years, surface water bodies have been contaminated due to unplanned urbanization, industrialization and defective sewerage systems. As these water bodies are a major part of diurnal and recreational activities, ... -
Assessing the interspecies and intraspecies diversity of Cas1 and Cas3 proteins of the CRISPR-Cas system in vibrio cholera and Escherichia coli strains
(Brac University, 2021-12)Cholera is an extremely virulent waterborne disease caused by the ingestion of food or water contaminated with pathogenic strains of Vibrio cholerae. On the other hand, pathogenic strains of E. coli, particularly Shiga-toxin ... -
Assessment on the microbial status of potable/ drinking water in Dhaka city and the comparative analysis of different regions of the city on antibiotic resistance
(2022-01)Dhaka City is home to nearly 22,478,000 people, but accessible drinking water sources are limited. Moreover, the minimal available water sources are polluted, rendering the Dhaka City population victim of water-borne ... -
