Genomic analysis of the correlation between CRISPR self-targeting spacers and prophage-related pathogenicity in Vibrio cholerae and Staphylococcus aureus
(Brac University, 2024-10)The interactions between bacteria and phages are intricate and dynamic, manifesting through two main life cycles: the lytic cycle, in which phages destroy their hosts via cell lysis, and the lysogenic cycle, where phage ... -
RISK 6 transcriptomic signature for diagnosis and treatment monitoring of extrapulmonary tuberculosis
(Brac University, 2024)Diagnosing extrapulmonary tuberculosis (EPTB) is challenging due to the diverse clinical manifestations of the disease and the requirement for invasive sampling and specialized processing. Moreover, current methods lack ... -
Biomedical waste analysis
(Brac University, 2024-10)The potential for biomedical waste to transmit infectious illnesses and include microorganisms resistant to antibiotics makes it a severe problem. The purpose of this study was to determine the microorganisms like ... -
Biomedical waste in healthcare: a comprehensive study on microbial analysis, radioactive analysis and prevalence of opportunistic bacteria
(Brac University, 2024-10)Proper biomedical waste (BMW) management is one of the crucial steps in ensuring public health. Covid 19 has given an emergence to maintain proper waste management. Microbial analysis and radioactivity tests are two ... -
An immunoinformatics approach to design a Novel mRNA vaccine against West Nile Virus
(Brac University, 2023-07)The West Nile Virus ( WNV) is a mosquito-transmitted flavivirus that causes a variety of ailments, from mild febrile illnesses to potentially lethal neuroinvasive encephalitis (Caren Chancey 1, 2015). The virus, which was ... -
Study of oxidative stress on growth and survivability comparison in between laboratory microorganisms and industrial wastewater microorganisms
(Brac University, 2023-07)Oxidative stress is one of the most common occurrence on microorganisms whether they are in natural environments, or chemically stressed environments, which typically causes natural cell apoptosis in microbes. ROS or ... -
Study of antibacterial activities of Azadirachta indica (Neem), Ocimum sanctum (Tulsi), and Punica granatum (Pomegranate peel) against vibrio cholerae
(Brac University, 2022-02)As multidrug-resistant (MDR) strains of Vibrio cholerae are emerging at an alarming rate, it has become a matter of importance to find and evaluate the already existing alternates to synthetic antibiotics. For several ... -
