The emergence of antimicrobial resistance genes over the years and their geographic bias
(Brac University, 2022-09)Antimicrobial agents have played a very intrinsic role in human and animal health since the beginning of the world. However, our irresponsibility has made this life saver, equally deadly. This study shows how much AMR has ... -
Decoding the role of uncharacterized Helicobacter Pylori proteins on differentially expressed genes in GC Pathogenesis
(Brac University, 2024-09)Gastric cancer (GC) is one of the most frequent and deadly cancers worldwide. Helicobacter pylori (H. pylori), a GC-associated bacterium, is critical to gastric pathogenesis. However, the specific molecular mechanisms ... -
Detection and characterization of antibiotic resistant and biofilm producing clinical isolates of Acinetobacter baumannii
(Brac University, 2024-08)Acinetobacter baumannii is an opportunistic pathogen that affects persons with weakened immune systems and causes nosocomial infections due to its antibiotic resistance. Because of the global proliferation of multidrug ... -
Effectiveness of microbial culture supernatants against multi-drug resistant microbes
(Brac University, 2022-09)The experiment started with collecting microorganisms from different sources like soil samples from 10 different places and storing them on CMCA, & SA, and MRS agar for yogurt samples from 7 different places. Among the ... -
Resuscitation of bacterial biofilm by sunlight: effects on different enteropathogenic bacteria
(Brac University, 2021-08)It is an established fact that most bacteria go through motile and sessile form during its lifetime. This transition has significant roles in seasonal outbreaks of certain bacterial diseases and bacterial pathogenesis. ... -
Helicobacter pylori and immune evasion in gastric carcinogenesis
(Brac University, 2024-10)Helicobacter pylori is found in approximately half of the global population, often without causing any symptoms of disease. Its infection is a significant public health concern and has been extensively researched for its ... -
Assessment of the antimicrobial sensitivity of Acinetobacter baumannii collected from the environment of neonatal ward of a rural hospital of Bangladesh
(Brac University, 2024-08)Background: Healthcare associated infection caused by multi drug resistant Acinetobacter baumannii is not only becoming increasingly prevalent in hospital settings but also becoming a huge challenge for the healthcare ... -
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 ... -
