Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a novel evolutionary divergent RNA virus, is responsible for the present devastating COVID-19 pandemic. To explore genomic signatures, we comprehensively analyzed 2,492 complete and/or near-complete genome sequences of SARS-CoV-2 strains reported from across globe to GISAID database up 30 March 2020. Genome-wide annotations revealed 1,516 nucleotide-level variations at different positions throughout entire SARS-CoV-2. Moreover,...
Abstract The emerged novel coronavirus severe acute respiratory syndrome 2 (SARS‐CoV‐2) has created a global health crisis that warrants an accurate and detailed characterization of the rapidly evolving viral genome for understanding its epidemiology, pathogenesis, containment.

Infecting millions of people, the SARS-CoV-2 is evolving at an unprecedented rate, demanding advanced and specified analytic pipeline to capture mutational spectra. In order explore mutations deletions in spike (S) protein - most-discussed we comprehensively analyzed 35,750 complete S protein-coding sequences through a custom Python-based pipeline. This GISAID-collected dataset until 24 June 2020 covered six continents five major climate zones. We identified 27,801 (77.77% sequences) mutated...
The increasing antimicrobial resistance in Providencia stuartii (P. stuartii) worldwide, particularly concerning for immunocompromised and burn patients, has raised concern Bangladesh, where the significance of this infectious opportunistic pathogen had been previously overlooked, prompting a need investigation. two strains P. SHNIBPS63 SHNIBPS71) isolated from wound swab critically injured patients were found to be multidrug-resistant showed all 22 antibiotics tested as well revealed...
Abstract The microbiome of the anaerobic digester (AD) regulates level energy production. To assess diversity and composition in different stages digestion, we collected 16 samples from AD cow dung (CD) origin. were categorized into four groups (Group-I, Group-II, Group-III Group-IV) based on production (CH 4 %), sequenced through whole metagenome sequencing (WMS). Group-I (n = 2) belonged to initial time whereas Group-II 5), Group-IV 4) had 21–34%, 47–58% 71–74% CH , respectively....
Foot-and-mouth disease virus (FMDV) serotype A exhibits a higher degree of genetic and antigenic diversity resulting in frequent vaccine failure due to serological mismatch between the heterologous strains. Currently, knowledge on molecular basis relationships among FMDVs is limited; nevertheless, intratype variation mutation(s) widely considered as main hurdle appropriate FMD development. Here, we studied variations four FMDV isolates, BAN/GA/Sa-197/2013 (BAN-197), BAN/CH/Sa-304/2016...

An immuno-informatics approach along with comparative genomic was applied to design multi-epitope-based peptide vaccine against SARS-CoV-2 combining antigenic epitopes S, M and E proteins. The tertiary structure predicted, refined validated using advanced bioinformatics...
Abstract Background The next-generation sequencing (NGS) technology facilitates in-depth study of host-pathogen metatranscriptome. We, therefore, implicated phylodynamic and transcriptomic approaches through NGS to know/understand the dengue virus (DENV) origin host response with fever. Methods In this study, blood serum RNA was extracted from 21 patients 3 healthy individuals. Total data were analyzed for phylogenetic, phylodynamic, differential express gene (DEG), ontology (GO) using...
The novel coronavirus, SARS-CoV-2, has caused the most unfathomable pandemic in history of humankind. Bangladesh is also a victim this critical situation. To investigate genomic features pathogen from Bangladesh, first complete genome virus very recently been published. Therefore, long-awaited questions regarding possible origin and typing strain(s) can now be answered. Here, we endeavor to mainly discuss published reports or online-accessed data (results) those issues present comprehensive...
Pseudomonas aeruginosa (P. aeruginosa) stands out as a key culprit in the colonization of burn wounds, instigating grave infections heightened severity. In this study, we have performed comparative whole genome analysis difficult to treat extensively drug resistant P. isolated from patient order elucidate genomic diversity, molecular patterns, mechanisms and genes responsible for conferring antimicrobial resistance virulence.
Fowl cholera (FC) caused by Pasteurella multocida is a highly contagious bacterial disease of global importance for poultry production. The severity and incidence FC P. may vary considerably depending on several factors associated with the host (including species age infected birds), environment, strain. This study aimed to investigate genetic diversity multidrug-resistant strains isolated from outbreaks in laying hens commercial farms Bangladesh.We collected 57 samples suspected FC,...
Foot-and-mouth disease (FMD) in cloven-hoofed animals is considered an economically devastating endemic countries like Bangladesh, where the livestock sector contributes to a greater portion of nation’s economy. The causative agent disease, foot-and-mouth virus (FMDV), equipped with higher mutational frequency challenges efficacy existing vaccine and control measures. This study, including 32 districts 71 outbreaks reveal epidemiological patterns trends FMDV over past 10 years (2012–2021),...
