Insights Into the Resistome of Bovine Clinical Mastitis Microbiome, a Key Factor in Disease Complication

Abstract: Bovine clinical mastitis (CM) is one of the most prevalent diseases caused by a wide range of resident microbes. The emergence of antimicrobial resistance in CM bacteria is well-known, however, the genomic resistance composition (the resistome) at the microbiome-level is not well characterized. In this study, we applied whole metagenome sequencing (WMS) to characterize the resistome of the CM microbiome, focusing on antibiotics and metals resistance, biofilm formation (BF), and quorum sensing (QS) along with in vitro resistance assays of six selected pathogens isolated from the same CM samples. The WMS generated an average of 21.13 million reads (post-processing) from 25 CM samples that mapped to 519 bacterial strains, of which 30.06% were previously unreported. We found a significant (P = 0.001) association between the resistomes and microbiome composition with no association with cattle breed, despite significant differences in microbiome diversity among breeds. The in vitro investigation determined that 76.2% of six selected pathogens considered "biofilm formers" actually formed biofilms and were also highly resistant to tetracycline, doxycycline, nalidixic acid, ampicillin, and chloramphenicol and remained sensitive to metals (Cr, Co, Ni, Cu, Zn) at varying concentrations. We also found bacterial flagellar movement and chemotaxis, regulation and cell signaling, and oxidative stress to be significantly associated with the pathophysiology of CM. Thus, identifying CM microbiomes, and analyzing their resistomes and genomic potentials will help improve the optimization of therapeutic schemes involving antibiotics and/or metals usage in the prevention and control of bovine CM.

Potential and economic feasibility of solar home systems implementation in Bangladesh

Abstract: Solar home systems (SHSs) are the real hope for electrification of the off-grid areas in Bangladesh by utilizing the solar energy in renewable and sustainable basis. This paper demonstrates the solar energy prospect, the present status and dissemination schemes of SHSs in off-grid and coastal areas of Bangladesh by several government and Non-government organizations (NGOs). The country has an average daily solar radiation ranges between 4–6.5 kWh/m2. Currently, more than 3.8 million SHSs of capacity range 10–135 Wp (watt peak) with a total capacity of 150 MW have been disseminated in rural and isolated areas in Bangladesh. In this paper, ten case studies of capacity 20 Wp, 30 Wp and 42 Wp were investigated to evaluate economic viability at two randomly selected villages in Sirajgonj district and Jessore district, Bangladesh. The analysis showed that the SHSs for small business enterprise and household with small income generation are economically viable rather than only household lighting.

Drivers, enablers, and barriers to prosumerism in Bangladesh: A sustainable solution to energy poverty?

Abstract: The concept of prosumers is well-established in the literature, but the role of a functioning prosumer in the least developed world has not yet been clarified. This paper attempts to show how prosumerism has evolved in Bangladesh, a pioneer, least developed country. It provides an insight into a functional prosumer-based renewable off-grid direct current (DC) network from the socioeconomic point of view, also reveals an operational peer-to-peer electricity trading system within this network. Prosumerism and its diverse impacts on the rural community are discussed. Along with the positive evolution of prosumerism, some barriers, drivers and enablers are explained with examples. Some negative impacts are also anticipated, but these can be overcome by implementing proper procedures in well-defined stages. Results show that prosumerism can improve the quality of life and greater socioeconomic awareness in least developed countries like Bangladesh. Prosumerism can be adopted in other similar countries by making long-term plans and learning from existing implementation in order to attain global sustainability. In addition, difficulties can be avoided with better planning and through commitment to research, aiming to improve general living standards.
