“…In accordance with studies conducted in Turkey and Italy, the prevalence of ETBF in Kolkata was almost equal in children with diarrhea and controls [23], [24]. However, reports from Vietnam, Turkey, Apache Indians in USA and Bangladesh, showed that the prevalence of ETBF was significantly high in cases and controls [25]–[27]. The highest prevalence of ETBF has been documented in countries such as Turkey (25%), Sweden (23%), Italy (17%), and in apache region of Arizona-USA (12%).…”

“…We observed that the co-infection rate of ETBF with other pathogens was 4% in children with diarrhea, which is almost similar to the findings from Vietnam [27] or with higher age group patients from Bangladesh and Turkey [7], [23]. The significantly associated pathogens found with ETBF include enteropathogenic E. coli (EPEC), Shigella spp, Campylobacter spp., Salmonella spp., Clostridium difficile, Entameoeba histolytica , C ryptosporidium , Giardia spp.…”

Although we screened for all these pathogens, we found no significant association between ETBF and other pathogens.…”

Case-Control Study on the Role of Enterotoxigenic Bacteroides fragilis as a Cause of Diarrhea among Children in Kolkata, India

A total of 874 fecal specimens (446 diarrheal cases and 428 controls) from diarrheal children admitted in the Infectious Diseases Hospital, Kolkata and age and sex matched asymptomatic subjects from an urban community were assessed for the prevalence of enterotoxigenic Bacteroides fragilis (ETBF). Isolates of B. fragilis were tested for the presence of enterotoxin gene (bft) by PCR. The detection rate of ETBF was 7.2% (63 of 874 specimens) that prevailed equally in diarrheal cases and controls (7.2% each; 32 of 446 cases and 31 of 428 controls). Male children up to one year age group was significantly (p<0.05) associated with ETBF infection as compared to children > 2 years of age in cases and controls. In 25 ETBF isolates, the bft gene was genotyped using PCR-RFLP and only two alleles were identified with prevalence rate of 40% and 60% for bft-1 and bft-3, respectively. All the ETBF isolates were susceptible for chloramphenicol and imipenem but resistant to clindamycin (48%), moxifloxacin (44%) and metronidazole (32%). Resistance of ETBF to moxifloxacin (44%) and metronidazole is an emerging trend. Pulsed-field gel electrophoresis (PFGE) revealed that majority of the ETBF isolates are genetically diverse. In the dendrogram analysis, two clusters were identified, one with ETBF resistant to 5–8 antimicrobials and the other cluster with metronidazole and moxifloxacin susceptible isolates from diarrheal cases. To our knowledge, this is the first detailed report on ETBF from India indicating its clinical importance and molecular characteristics.

“…The methods for isolation and identification of the diarrheal pathogens: rotavirus A, diarrheagenic E. coli, Shigella spp, Salmonella spp, Vibrio cholerae and enterotoxigenic Bacteroides fragilis, have been published in detail previously and are briefly described below. [18][19][20] For group A rotavirus: stool samples were analyzed for rotavirus A by using the IDEA rotavirus enzyme-linked immunosorbent assay kit (DAKO Ltd, Ely, UK), according to the instructions of the manufacturer. This test is a qualitative enzyme immunoassay for the detection of rotavirus (group A) in human fecal samples.…”

Group A rotavirus, diarrheagenic Escherichia coli, Shigella spp, and enterotoxigenic Bacteroides fragilis play an important role in causing diarrhea in children in Hanoi, Vietnam. Epidemiological factors such as lack of fresh water supply, unhygienic septic tank, low family income, lack of health information, and low educational level of parents could contribute to the morbidity of diarrhea in children.
