Arsenic and cadmium in food-chain in Bangladesh--an exploratory studyArsenic contamination of tubewell water is a major public-health problem in Bangladesh. In the recent years, the use of shallow and deep tubewell water for irrigation and the use of excess amount of cheap fertilizers and...
Molecular typing of Vibrio cholerae O1 isolates from Thailand by pulsed-field gel electrophoresisThe aim of the present study was to genotypically characterize Vibrio cholerae strains isolated from cholera patients in various provinces of Thailand. Two hundred and forty V. cholerae O1 strains, isolated from patients with c...
Successful treatment of rotavirus-induced diarrhoea in suckling mice with egg yolk immunoglobulinThe role of specific immunoglobulins at mucosal sites in imparting protection against disease, such as rotavirus-associated diarrhoea, is well-established. Oral immunoglobulin therapy with egg yolk-derived anti-rotavirus immunoglobulins has previously ...
Lymphocytes in the intestine: role and distributionOnce a pathogen penetrates the surface epithelium, the process of immune activation begins. The pathogen is transported across the intestinal epithelium by M cells and presented to the underlying lymphocytes in Peyer's patches b...
Rapid detection of haemophilus influenzae type b in Bangladeshi children with pneumonia and meningitis by PCR and analysis of antimicrobial resistanceA polymerase chain reaction (PCR) assay with primers from bexA gene was compared with culture for he detection of Haemophilus influenzae ype b (Hib) in clinical samples from children with pneumonia and meningitis. Of 20...
A modified routine analysis of arsenic content in drinking-water in Bangladesh by hydride generation-atomic absorption spectrophotometryThe high prevalence of elevated levels of arsenic in drinking-water in many countries, including Bangladesh, has necessitated the development of reliable and rapid methods for the determination of a wide range of arsenic concentrati...
Importance of Escherichia coli strains producing verotoxinsThe production of a heat-labile protein unrelated to cholera toxin was described in the 1960s in studies of Escherichia coli isolated from animals. However, it was not until 1982 when Riley et al. reported an outbreak ...
Immunization Divide: who do get vaccinated in BangladeshThis paper examines inequalities in the use of, and access to, vaccination service in Bangladesh by analyzing national and small area-based datasets. The analysis showed that female children had a lower immunization coverage than...
Emergence of multidrug-resistant salmonella gloucester and salmonella typhimurium in BangladeshInfections due to non-typhoid Salmonella, resistant to antibiotics, have recently emerged as an important health problem worldwide. Antibiotic resistance was studied by the disc-diffusion method among 3,876 (2.78%) non-typhoid Salmonella isolates&...
Prevalence and risk factors of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus infections among drug addicts in BangladeshThis cross-sectional study investigated the prevalence and risk factors of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections among 266 drug users attending a drug-addiction treatment cent...
Analysis of human rotavirus G serotype in Bangladesh by enzyme-linked immunosorbent assay and polymerase chain reactionDistribution of human rotavirus G serotype was investigated by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) with faecal specimens obtained from children with diarrhoea in Bangladesh. By ELISA, subgroup and...
Severity of cholera during concurrent infections with other enteric pathogensIn a clinic-based case-control study in Bangladesh we evaluated whether children with diarrhoea due to V. cholerae O1 in association with other enteric pathogen(s) are likely to manifest more severe disease as indicated by deve...
Evaluation of a probe hybridisation serotyping method for group A rotavirusSerotype-specificity and sensitivity of oligonucleotide probes to serotype human rotavinises was assessed. Probes could detect as little as 63 ng of homologous RNA and none reacted with as much as 100 ng of hcterologous RNA....
Production of mucinase and neuraminidase and binding of Shigella to intestinal mucinProduction of mucinase and neuraminidase by Shigella spp. and their ability to bind to mucin was investigated. All four species of Shigella produced these enzymes. Virulent and avirulent pairs of Shigella did not differ in ...
Isolation of enterotoxigenic Vibrio cholerae non-01 from the Buriganga river and two ponds of Dhaka, BangladeshVibrio cholerae 01 is usually considered the most toxigenic member of the Vibrionaceae and V. cholerae non-01 isolated from the environment is non-toxigenic. In our survey of the pollution of some aquatic environments in and...
