A 6-year retrospective study of bloodstream Salmonella infection and antibiotic susceptibility of Salmonella enterica serovar Typhi and Paratyphi in a tertiary care hospital in Dhaka, Bangladesh
AbstractObjectivesBloodstream infections (BSI) are a serious cause of morbidity and mortality worldwide. Emerging antimicrobial drug resistance among bacterial pathogens causing BSI can limit therapeutic options and complicate patient management. This retrospective study was conducted to determine trends in Salmonella BSI and antibiotic susceptibility patterns over 6 years (2008–2013) in a tertiary care hospital in Dhaka, Bangladesh.MethodsA total of 3584 blood samples were collected from patients with clinically diagnosed enteric fever at Dhaka Medical College Hospital, Dhaka from January 2008 to December 2013. Isolates of Salmonella enterica serovars Typhi and Paratyphi were identified by standard microbiological and biochemical procedures.ResultsA total of 168 isolates of S. enterica serovar Typhi and 160 isolates of S. enterica serovar Paratyphi were found. The average prevalence rate of Salmonella in the blood was 9.15%. Young patients, neonates, and elderly individuals were more prone to Salmonella infection than other patients, and females were more susceptible to Salmonella septicemia than males. Among Salmonella spp. isolates, 20.92% were multidrug resistant and showed high resistance against amoxicillin, trimethoprim–sulfamethoxazole, ciprofloxacin, nalidixic acid, and chloramphenicol. Resistance rates to cefipime, cefixime, and ceftriaxone are increasing slowly. Among Salmonella spp. isolates, 57.01% showed extended-spectrum β-lactamase production capability.ConclusionSpecific antibiotic utilization strategies such as antibiotic restriction, combination therapy and usage according to standard antimicrobial susceptibility testing may help decrease or prevent the emergence of resistance and incidence of BSI
A signature-based data security and authentication framework for internet of things applications
Internet of things (IoT) is the next big revolution in modernized network technologies connecting a massive number of heterogeneous smart appliances and physical objects. Owing to these technologies' novelty, various issues are characterized by security concerns are the most prioritized issue. A review of existing security approaches highlights that they are very particular about the solution towards a specific attack and cannot resist any unknown attacker. Therefore, this manuscript presents a novel computational model that introduces a unique authentication process using a simplified encryption strategy. The simulated study outcome shows that the proposed system offers efficient security and efficient data transmission performance in the presence of an unknown adversary. Hence, the study outcome exhibits better effects than frequently used security solutions when implemented in a vulnerable IoT environment
Evaluation of the performance of gum guar varieties in north eastern Karnataka, India
The climatic situation in north eastern parts of Karnataka (except Bidar district) is almost similar to that of Rajastan. There is considerable area under rainfed situations and guar being a highly drought and temperature tolerant summer annual legume crop, there is hope for guar as an alternate and contingent crop during drought year in this region. With this objective effort were made to introduce, evaluate and to identify suitable gum guar varieties for North eastern parts of Karnataka. Ten gum guar varieties developed, released and cultivated in Rajasthan, Haryana and Gujarat state were evaluated in Agricultural Research Stations (ARS) located in Bidar, Gulbarga, Yadgiri, Bellary and Raichur districts of Karnataka during Kharif 2013-14. At Bidar, the top entry with respect to yield was HG-884 (679.00 Kg/ Ha), Variety RGC-1031 (793.00 Kg/Ha) performed well with respect to seed yield in Gulbarga district. Genotypes GAUG-13 (614.00 Kg/Ha) and RGC-986 (501.00 Kg/Ha) recorded higher seed yield respectively, in Bellary and Yadgiri district. At Raichur GAUG-13, recorded highest seed yield of 1432.00 Kg/Ha. Over the locations genotype GAUG-13 recorded highest seed yield of 759.00 Kg/Ha followed by HG-884 (700.40 Kg/Ha) and RGC-986 (696.60 Kg/Ha). The varieties tested exhibited considerable significance differences among themselves at four locations, except at one location (Agricultural Research Station, Bheemarayanagudi, Yadgir district).

Bacterial Community Profiling of Tropical Freshwaters in Bangladesh
Seasonal and spatial variations in the bacterial communities of two tropical freshwater sources in Bangladesh, Lake Dhanmondi in central Dhaka, and a pond in the outskirts of Dhaka, were assessed and compared using PCR-DGGE and deep sequencing of 16S rRNA genes, as well as heterotrophic enrichments using water samples collected at nine different time points during 1 year. Temporal and spatial variations of common aquatic bacterial genera were observed, but no clear seasonal variations could be depicted. The major bacterial genera identified from these two sites were members of the Proteobacteria, Cyanobacteria, Actinobacteria, Bacteroidetes, Chlorobi, Chloroflexi, Verrucomicrobia, and Firmicutes. Among the proteobacterial groups, members of the α-, β-, and γ- Proteobacteria predominated. γ- Proteobacteria belonging to the Escherichia coli/Shigella group even the diarrheagenic pathotypes of E. coli e.g., EPEC and ETEC were detected in most samples throughout the year, with no apparent correlations with other microbial groups. The other pathotypes, EHEC, EAEC, and EIEC/Shigella spp. were also detected occasionally. This study represents the first thorough analysis of the microbial diversity of tropical freshwater systems in Bangladesh.publishedVersio
