A comparative study of Environment Risk Assessment (ERA) guidelines of developing and developed countries including Bangladesh
(Brac University, 2021-05)Genetically Engineered (GE) plants are the demand of time for increased demand of food. According to the report of International Service for the Acquisition of Agri-biotech Applications (ISAAA), a total of 29 countries ... -
Comparison of genotypic and phenotypic method for detection of Enterotoxigenic Escheichia coli isolated from diarrheal patients
(BRAC University, 2010-11)Enterotoxigenic Escherichia coli (ETEC) is one of the main causes of childhood diarrhea and in travelers in developing countries . ETEC expresses one or both of two different enterotoxin subtypes : heat-stable toxins ... -
Comparison of Lipopolysaccharide (LPS) specific IgA and IgG avidity maturation between Vivotif Vaccinees and naturally infected enteric patients in Bangladesh
(BRAC University, 2014-08)Enteric fever, primarily caused by Salmonella enterica serovar Typhi and Paratyphi, is a potentially life-threatening systemic disease. Characterized by fever, malaise and diffused abdominal pain, it can lead to delirium, ... -
Comparison of memory B-Cell immune responses among different age groups after oral cholera vaccination
(BRAC University, 2011-12)Infection with Nbrio cholerae Olcauses dehydrating diarrhea, although it is now treatable disease with low case-fatality in settings with appropriate medical care . However, cholera continues to impose considerable ... -
Comparison of Xpert MTB/RIFAssay with smear microscopy and culture for the detection of pulmonary tuberculosis
(BRAC University, 2017-10)Tuberculosis (TB) remains one of the world’s most serious diseases, leading to more than one million deaths each year. The emergence of drug-resistant strains of Mycobacterium tuberculosis poses a threat to tuberculosis ... -
Correlation between the prevalence of plasmids and AMR genes in the environmental isolates of different bacterial species
(2023-07)Bacterial gene transfer is responsible for spread of antibiotic resistance in bacteria and evolution of bacteria which can be a threat of virulence as well play role in maintenance. Horizontal gene transfer (HGT) is the ... -
Correlation of mutations with the minimum inhibitory concentrations of isoniazid drug among isoniazid-resistant Mycobacterium tuberculosis isolates in Bangladesh
(Brac University, 2023-08)Tuberculosis is still one of the major causes of mortality in the globe. Isoniazid (INH), a first-line medication used to treat tuberculosis is becoming increasingly resistant. With the rise of INH resistance we need more ... -
Degradation of dyes used in textile Industries by bacteria isolated from local textile effluents
(BRAC University, 2017-06)The effluent discharges from textile processing industries contain a significant amount of unreacted dyes. Release of these dyes into the environment causes toxic effects to the environment. The application of microorganisms ... -
