RS1 satellite phage promotes diversity of toxigenic Vibrio cholerae by driving CTX prophage loss and elimination of lysogenic immunity. - Infection and immunity
In El Tor biotype strains of toxigenic Vibrio cholerae, the CTXϕ prophage often resides adjacent to a chromosomally integrated satellite phage genome, RS1, which produces RS1ϕ particles by using CTX prophage-encoded morphogenesis proteins. RS1 encodes RstC, an antirepressor against the CTXϕ repressor RstR, which cooperates with the host-encoded LexA protein to maintain CTXϕ lysogeny. We found that superinfection of toxigenic El Tor strains with RS1ϕ, followed by inoculation of the transductants into the adult rabbit intestine, caused elimination of the resident CTX prophage-producing nontoxigenic derivatives at a high frequency. Further studies using recA deletion mutants and a cloned rstC gene showed that the excision event was recA dependent and that introduction of additional copies of the cloned rstC gene instead of infection with RS1ϕ was sufficient to enhance CTXϕ elimination. Our data suggest that once it is excised from the chromosome, the elimination of CTX prophage from host cells is driven by the inability to reestablish CTXϕ lysogeny while RstC is overexpressed. However, with eventual loss of the additional copies of rstC, the nontoxigenic derivatives can act as precursors of new toxigenic strains by acquiring the CTX prophage either through reinfection with CTXϕ or by chitin-induced transformation. These results provide new insights into the role of RS1ϕ in V. cholerae evolution and the emergence of highly pathogenic clones, such as the variant strains associated with recent devastating epidemics of cholera in Asia, sub-Saharan Africa, and Haiti.Copyright © 2014, American Society for Microbiology.

High prevalence of noroviruses among hospitalized diarrheal patients in Bangladesh, 2011. - Journal of infection in developing countries
Norovirus is not usually investigated in diarrheal patients in Bangladesh which may account for the many cases where no pathogens are identified.Stool specimens collected from diarrheal patients from three hospitals in Bangladesh during 2011 were investigated for norovirus RNA using real-time RT-PCR assay with norovirus type specific primers and probes.Of the 257 stool specimens tested, 28.4 % were norovirus positive. GII (71.2%) was the predominant strain followed by GI (20.5%), GI+GII (6.8%) and GIV (1.4%). Half of the norovirus positive stools (n=37) were co-infected with other pathogens.Continued surveillance of norovirus together with other viral and bacterial pathogens in hospitalized gastroenteritis patients as well as in the community will further elucidate the role and burden of different pathogens in diarrheal diseases.
Epidemiology and genetic diversity of human astrovirus infection among hospitalized patients with acute diarrhea in Bangladesh from 2010 to 2012. - Journal of clinical virology : the official publication of the Pan American Society for Clinical Virology
Globally, human astroviruses (HAstVs) have emerged as another common cause of non-bacterial acute gastroenteritis. Limited data exist on the epidemiology and genetic diversity of HAstVs in Bangladesh.We describe the epidemiology of HAstV-associated diarrhea among hospitalized patients, including HAstV genotypes, clinical symptoms and co-infecting pathogens.Stool samples were collected from an ongoing diarrhea etiology surveillance during 2010-2012. HAstV was detected using RT-PCR and positive samples were subsequently tested for other common viral and bacterial pathogens. Phylogenetic analysis was performed and genotyped HAstV sequences were compared with previously reported Bangladeshi HAstV strains.Of 826 fecal specimens, HAstV was detected in 26 cases (3.1%) and the majority of these cases (92%) was observed in children under 3 years of age. For 6 out of the 26 cases (23%) no other co-infecting pathogens were observed, whereas for the 20 remaining cases (77%) a variety of other known enteric viral and bacterial pathogens were observed. Based on the overlap region between ORF1b (RdRp) and ORF2 (capsid), five different genotypes (HAstV-1, -2, -3, -5 and -6) were identified circulating during the study period, with HAstV-1 being the predominant type. Genetic analysis revealed that HAstV-1 strains detected in this study were distantly related (<90% similarity of the capsid protein on the nt level) with HAstV-1 strains previously reported from Bangladesh.Our study provides an epidemiological overview and genetic diversity of HAstVs associated with acute diarrhea in Bangladesh.Copyright © 2013 Elsevier B.V.

Novel intergenotype human norovirus recombinant GII.16/GII.3 in Bangladesh. - Infection, genetics and evolution : journal of molecular epidemiology and evolutionary genetics in infectious diseases
Noroviruses (NoVs) are one of the major etiological agents of acute gastroenteritis in all age groups. In this study, we identified an intergenotype NoV recombinant strain in the fecal specimens of two male infants with acute diarrhea in Bangladesh. Phylogenetic analysis showed that the identified strains were recombinant NoV strains with a GII.3 capsid and a GII.16 polymerase gene. The recombination breakpoint was located in the ORF1/ORF2 overlap region. To the best of our knowledge this is the first report of a NoV recombinant GII.16/GII.3 strain worldwide.Copyright © 2013 Elsevier B.V. All rights reserved.
Tobacco use among health care workers in southwestern Saudi Arabia. - BioMed research international
The present study targeted health care workers (HCWs) in Governmental Hospitals and Primary Health Care Centers in Abha City, southwestern Saudi Arabia. An anonymous self-report questionnaire was used to assess tobacco use and the reasons for smoking. The present study included 736 HCWs. The overall prevalence of tobacco use amounted to 26.3% (14.8% current and 11.5% former users). In a binary logistic regression analysis, males were found significantly more prone to smoke compared to females (aOR = 3.081, 95% CI: 2.004-4.739). Similarly, parental history of tobacco use was found to be a significant risk factor (aOR = 1.540, 95% CI: 1.040-2.278). Among current users, 89.9% were interested in quitting and 66.1% tried before to quit. The prevalence of smoking among HCWs in the present study, besides being a public health problem, represents a potential barrier in involving this group as a first line for tobacco control. There is a need for a national intervention programme in the country in a tailored manner for HCWs to control tobacco use parallel to the running national program for public. These interventions should begin early in basic medical education and to be applied continually during one's medical career.
Breast cancer knowledge and related behaviors among women in Abha City, southwestern Saudi Arabia. - Journal of cancer education : the official journal of the American Association for Cancer Education
Breast cancer is the most common malignancy among women in Saudi Arabia. A cross-sectional study was conducted on 1,092 women attending urban primary health care centers in Abha City southwestern Saudi Arabia about breast cancer knowledge, attitudes, and related practices. Only 22.0% heard about mammography, and 41.5% heard about breast self-examination (BSE). More than half of the women in the study identified changes occurring in case of breast cancer and identified risk factors. Only 8.3% were examined by clinical breast examination (CBE), 6.2% were examined by mammography, and 29.7% performed BSE. The study points to the insufficient knowledge of women and the low practice of BSE, CBE, and mammography. Public awareness should be enhanced by all available means including mass media, schools, social gatherings, and waiting areas in primary health care centers. There is an urgent need for continuing medical education programs for health care workers in the region concerning breast cancer.
A novel norovirus recombinant strain GII.4/GII.21 in Bangladesh, 2011. - Virus genes
We identified a novel inter-genotype recombinant norovirus strain, Dhaka85/2011/BGD, collected from a stool specimen of a nine-month-old infant who was hospitalized with diarrhea. Molecular investigation and phylogenetic analysis classified its RNA polymerase gene as GII.4-like, which commonly circulates in humans. The capsid gene was classified as GII.21-like, most likely originated from water. The discovery of this novel strain is an illustration of the enormous diversity among the norovirus strains, especially in developing countries and has important implications for future vaccine strategies.
Factors influencing stillbirth in bangladesh: a case-control study. - Paediatric and perinatal epidemiology
Studies on a limited scale in urban settings of Bangladesh report stillbirth rates that do not specifically provide information on the situation of underprivileged slum populations. This study aims to estimate the prevalence of, and risk factors associated with, stillbirth in a developing population.A case-control study was conducted on women having a singleton birth between November 2008 and April 2009 in 34 slum areas in Dhaka. Data were collected on 231 women with stillbirth (cases) and 464 women having livebirth (controls). This study utilised the records of the Manoshi programme and supplemented it with data obtained through interview of the women.The stillbirth rate was 26 per 1000 total births, of which 62% occurred during the intrapartum period. Obstetrical complications contributed to 61.4% of stillbirths. Illiterate women [odds ratio (OR) 1.6 [95% confidence interval (CI) 1.1, 2.2]], women aged ≥35 years (OR 2.9 [95% CI 1.5, 25.5]), preterm delivery (OR 5.2 [95% CI, 3.2, 8.5]), prolonged labour (OR 2.8 [95% CI 1.6, 4.6]) and failure of labour progress (OR 2.4 [95% CI 1.1, 5.5]) were significant maternal risk factors, while decreased fetal movement, fetal malpresentation and fetal distress were the fetal risk factors associated with stillbirth.Risk factors associated with stillbirths are amenable to intervention. There is an urgent need to educate pregnant women about risk factors for stillbirths during antenatal visits. Encouraging women to deliver at health facilities and better management of obstetrical complications may help reduce the burden of stillbirths in Bangladesh.© 2012 Blackwell Publishing Ltd.
Preliminary study of the immunostimulating activity of an ayurvedic preparation, Kanakasava, on the splenic cells of BALB/c mice in vitro. - Pharmaceutical biology
Immunostimulant plays an important role to prevent infections when defensive capacity of body is impaired, commonly occur with aging, cancer, diabetes, and sepsis. Kanakasava (KNK) is a polyherbal ayurvedic preparation used since ancient times for the treatment of respiratory diseases and to improve immunity.The present study evaluated the immunostimulating potential of KNK.The immunostimulating activity of KNK was evaluated by measuring immunoglobulin M (IgM) production and splenocyte proliferation in vitro. BALB/c mice splenocytes were treated with 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, and 4% (v/v) of KNK, and the cells were subcultured at 37°C, humidified atmosphere containing 5% CO(2) for 120 h. The production of IgM in cultured supernatants were determined by an enzyme-linked immunosorbent assay (ELISA) and the proliferations of cells were measured by the 3-(4,5-dimethylthiazol-2-y)-2,5-diphenylterazolium bromide (MTT) method.KNK at the doses of 0.25, 0.5, 0.75, 1, and 1.5% (v/v) significantly augmented polyclonal IgM production (1.211, 1.260, 1.274, 1.180, and 1.028 µg/mL, respectively) compared to control (0.246 µg/mL). Similarly, the same doses stimulated the proliferation of splenocytes as well (Abs. 0.270, 0.281, 0.368, 0.328, and 0.301, respectively, measured at 570 nm) compared to untreated cells (Abs. 0.137). The activity of KNK was not retarded by the treatment of cells with polymixin B. Thus, our results demonstrate that KNK possesses immunostimulating potential that acts through the induction of lymphocytes for proliferation and IgM production.KNK may be useful for strengthening immune responses in case of insufficient or impaired immunity.
Role of Shrimp Chitin in the Ecology of Toxigenic Vibrio cholerae and Cholera Transmission. - Frontiers in microbiology
Seasonal plankton blooms correlate with occurrence of cholera in Bangladesh, although the mechanism of how dormant Vibrio cholerae, enduring interepidemic period in biofilms and plankton, initiates seasonal cholera is not fully understood. In this study, laboratory microcosms prepared with estuarine Mathbaria water (MW) samples supported active growth of toxigenic V. cholerae O1 up to 7 weeks as opposed to 6 months when microcosms were supplemented with dehydrated shrimp chitin chips (CC) as the single source of nutrient. Bacterial counting and detection of wbe and ctxA genes were done employing culture, direct fluorescent antibody (DFA) assay, and multiplex-polymerase chain reaction methods. In MW microcosm, the aqueous phase became clear as the non-culturable cells settled, whereas the aqueous phase of the MW-CC microcosm became turbid from bacterial growth stimulated by chitin. Bacterial chitin degradation and biofilm formation proceeded from an initial steady state to a gradually declining bacterial culturable count. V. cholerae within the microenvironments of chitin and chitin-associated biofilms remained metabolically active even in a high acidic environment without losing either viability or virulence. It is concluded that the abundance of chitin that occurs during blooms plays an important role in the aquatic life cycle of V. cholerae and, ultimately, in the seasonal transmission of cholera.
