Highly pathogenic avian influenza (HPAI) H5N1 and low (LPAI) H9N2 viruses have been recognized as threats to public health in Bangladesh since 2007. Although live bird markets (LBMs) implicated the transmission, dissemination, circulation of these viruses, an in-depth analysis dynamics transmission at human–animal interface has lacking. Here we present evaluate epidemiological findings from active surveillance conducted among poultry various production sectors 2008 2016. Overall, prevalence...
In Bangladesh rhesus macaques (Macaca mulatta) are found in forested habitats and urban areas. From 2005 to 2010, we investigated the distribution of throughout country. Populations were estimated by line transect, point sampling direct counting. A total 37 groups 16 localities recorded Overall, group size areas ranged from 22 91 individuals, with a mean 41.3 ± 16.7. Rhesus mostly near Hindu communities. Nearly five times as many (n= 176) observed Overall natural varied 10 78 30.2 10.9. Of...
Highly pathogenic avian influenza A(H5N8) clade 2.3.4.4 virus emerged in 2016 and spread to Russia, Europe, Africa. Our analysis of viruses from domestic ducks at Tanguar haor, Bangladesh, showed genetic similarities with other wild birds central Asia, suggesting their potential role the genesis A(H5N8).
Highly pathogenic H5N1 and low H9N2 influenza viruses are endemic to poultry markets in Bangladesh have cocirculated since 2008. circulated constantly the markets, whereas highly occurred sporadically, with peaks of activity cooler months. Thirty isolated from were characterized by antigenic, molecular, phylogenetic analyses. clades 2.2.2 2.3.2.1 live bird only. Phylogenetic analysis 30 isolates revealed multiple introductions Bangladesh. There was no reassortment between local genotype,...
Highly pathogenic avian influenza H5N1 viruses were first isolated in Bangladesh February 2007. Subsequently, clades 2.2.2, 2.3.4.2 and 2.3.2.1a identified Bangladesh, our previous surveillance data revealed that by the end of 2014, circulating exclusively comprised clade 2.3.2.1a. We recently determined status conducting live poultry markets waterfowl wetland areas from 2015 through 2016. Until April 2015, persisted without any change genotype. However, June we a new genotype viruses,...
In 2011, avian influenza surveillance at the Bangladesh live bird markets (LBMs) showed complete replacement of highly pathogenic (HPAI) H5N1 virus clade 2.2.2 (Qinghai-like lineage) by HPAI 2.3.2.1. This clade, which continues to circulate in and neighboring countries, is an intra-and interclade reassortant; its HA, polymerase basic 1 (PB1), (PA), nonstructural (NS) genes come from subclade 2.3.2.1a; 2 (PB2) comes 2.3.2.1c; NA, nucleocapsid protein (NP), matrix (M) gene 2.3.4.2. The H9N2...
Background: Tuberculosis (TB) remains one of the deadliest communicable diseases. is caused by Mycobacterium tuberculosis and classified as Pulmonary (PTB) Extra (EPTB). EPTB account for 15-20 % cases tuberculosis. diagnosis challenging due to inadequate sample volume, pauci-bacillary nature unusual clinical presentation. There are number tests available but conventional microscopy has low sensitivity although culture gold standard method, it takes longer time yielding positive result. On...
The study was carried out to assess the mammalian diversity and conservation in Baraiyadhala National Park between October 2021 June 2023 spanning a total of 78 field days. Field data were collected following combination different methods including transect walk, night survey, mist netting camera trapping. Ten automated, infrared sensor traps set up at 48 trap station for 14 months covering 2793 Fifty-five species mammals recorded which 41.82% rare, followed by 29.09% common, 16.36% uncommon...
H9N2 avian influenza viruses are continuously monitored by the World Health Organization because they endemic; continually reassort with H5N1, H7N9 and H10N8 viruses; periodically cause human infections. We characterized carrying internal genes from highly pathogenic H7N3 viruses, which were isolated chickens or quail live-bird markets in Bangladesh between 2010 2013. All of used this study carried mammalian host-specific mutations. studied their replication kinetics normal bronchoepithelial...
Since November 2008, we have conducted active avian influenza surveillance in Bangladesh. Clades 2.2.2, 2.3.4.2, and 2.3.2.1a of highly pathogenic H5N1 viruses all been identified Bangladeshi live poultry markets (LPMs), although, since the end 2014, exclusively from clade 2.3.2.1a. In June 2015, a new reassortant virus (H5N1-R1) was identified, containing haemagglutinin, neuraminidase, matrix genes circulating Bangladesh 2011, plus five other Eurasian-lineage low A (LPAI) viruses. Here...
To explore relationship among perceived stress regarding loneliness, interpersonal trust and institutional of expatriates during the early COVID-19 period (from 30th March to May 2020).Data from 21,439 were extracted COVIDiSTRESS global survey. The outcome variable was stress. explanatory variables age, (interpersonal institutional). Pairwise correlation, structural equation modelling used determine variables.The majority female (73.85%), married (60.20%), had college degree (47.76%),...
Influenza virological surveillance was conducted in Bangladesh from January to December 2021 live poultry markets (LPMs) and Tanguar Haor, a wetland region where domestic ducks have frequent contact with migratory birds. The predominant viruses circulating LPMs were low pathogenic avian influenza (LPAI) H9N2 clade 2.3.2.1a highly (HPAI) H5N1 viruses. Additional LPAIs found both LPM (H4N6) Haor wetlands (H7N7). Genetic analyses of these strongly suggested long-distance movement along the...
Abstract The H9N2 influenza viruses that have become established in Bangladeshi live poultry markets possess five gene segments of the highly pathogenic H7N3 avian virus. We assessed replication, transmission, and disease potential three chickens New World quail. Each virus replicated to high titers transmitted by airborne route contacts both species. Infected showed no signs, differed their quail were more susceptible than shed after transmission for 10 days. Consequently, are a threat...
Activity pattern of white-breasted waterhen (Amaurornis phoenicurus) was studied during May 2007 to April 2008 at Jahangirnagar University Campus, Savar, Dhaka, Bangladesh. They spent most the daily time (35.46%) for foraging and feeding. Hiding second highest activity (26.75%) while moving, preening, calling, resting activities changing other wetland birds constituted 11.33%, 8.59%, 6.13%, 5.20% 5.12%, respectively. Breeding season lasted from February July with breeding found in (9.41%)....
In Bangladesh, free-range duck farms provide opportunities for the generation of novel influenza A viruses as evidenced by emergence an unusual A(H1N7) virus in 2023. Continued surveillance such environments potential with properties remains a priority.
Migratory birds play a major role in spreading influenza viruses over long distances. We report highly pathogenic avian A(H5N6) migratory and resident ducks Bangladesh. The were genetically similar to detected wild China Mongolia, suggesting migration-associated dissemination of these zoonotic pathogens.
From April 2018 to October 2019, we continued active surveillance for influenza viruses in Bangladeshi live poultry markets (LPMs) and Tanguar Haor, a wetland region of Bangladesh where domestic ducks have frequent contact with migratory birds. The predominant virus subtypes circulating the LPMs were low pathogenic avian (LPAI) H9N2 clade 2.3.2.1a highly (HPAI) H5N1 H5N1-R1 genotype, like those found previous years. Viruses H5N1-R2 which previously reported as co-circulating genotype LPM,...
