Crimean-Congo hemorrhagic fever (CCHF) has been reported from all provinces of Pakistan. Little is known about the seasonal variations in the disease and its association with weather conditions. In this study, we explored time-series data about monthly number of CCHF admissions (2007-2010) in three public sector hospitals of Quetta-the capital city of Baluchistan province of Pakistan. Cosinor analysis was carried out to investigate seasonality in the data. To assess the effect of average monthly ambient temperature (°C) on disease, a distributed lag nonlinear model (DLNM) was applied...

Orf is a DNA parapoxvirus transmitted to humans by contact with infected goats and sheep. Many complications have been reported after Orf infection including erythema multiforme. A few cases of auto-immune bullous dermatosis complicating Orf disease have been reported to date, usually characterized by tense blisters eruptions with or without mucosal involvement, linear deposition of C3, IgG and/or IgA along the basement membrane and negativity of indirect immunofluorescence analysis and ELISA assays (performed in 4 of 11 reported cases) against target antigens of bullous pemphigoid, mucous membrane pemphigoid or epidermolysis bullosa acquisita, except one case of mucosal pemphigoid with antilaminin-332 antibodies...

Farm animal genetic resources are threatened worldwide. Participation in markets, while representing a crucial way out of poverty for many smallholders, affects genetic management choices with associated sustainability concerns. This paper proposes a contextualized study of the interactions between markets and animal genetic resources management, in the case of sheep markets in Ouagadougou, Burkina Faso. It focusses on the organization of marketing chains and the valuation of genetic characteristics by value chain actors...

Ethanol is an important target for the renewable production of liquid transportation fuels. It can be produced biologically from pyruvate, via pyruvate decarboxylase, or from acetyl-CoA, by alcohol dehydrogenase E (AdhE). Thermophilic bacteria utilize AdhE, which is a bifunctional enzyme that contains both acetaldehyde dehydrogenase and alcohol dehydrogenase activities. Many of these organisms also contain a separate alcohol dehydrogenase (AdhA) that generates ethanol from acetaldehyde, although the role of AdhA in ethanol production is typically not clear...

The protein AdhA from the cyanobacterium Synechocystis sp. PCC 6803 (hereafter Synechocystis) has been previously reported to show alcohol dehydrogenase activity towards ethanol and both NAD and NADP. This protein is currently being used in genetically modified strains of Synechocystis capable of synthesizing ethanol showing the highest ethanol productivities. In the present work, mutant strains of Synechocystis lacking AdhA have been constructed and tested for tolerance to ethanol. The lack of AdhA in the wild-type strain reduces survival to externally added ethanol at lethal concentration of 4% (v/v)...

Cyanobacteria are photoautotrophic microorganisms, which are increasingly being used as microbial cell factories to produce for example ethanol directly from solar energy and CO2. Here we analyzed the effects of different salt concentrations on an ethanol-producing strain of Synechocystis sp. PCC 6803 that over-expresses the pyruvate decarboxylase (pdc) from Zymomonas mobilis and the native alcohol dehydrogenase (adhA). Moderate salinities of 2% NaCl had no negative impact on ethanol production, whereas the addition of 4% NaCl resulted in significantly decreased ethanol yields compared to low salt conditions...

Thermoanaerobacter ethanolicus is a promising candidate for biofuel production due to the broad range of substrates it can utilize and its high ethanol yield compared to other thermophilic bacteria, such as Clostridium thermocellum. Three alcohol dehydrogenases, AdhA, AdhB and AdhE, play key roles in ethanol formation. To study their physiological roles during ethanol formation, we deleted them separately and in combination. Previously, it has been thought that both AdhB and AdhE were bifunctional alcohol dehydrogenases...

Here, we report a pH- and thermo-responsive fluorescent nanomaterial of functionalized reduced graphene oxide (rGO) with cross-linked polymer produced via catechol-boronate diol binding mechanism. When conjugated with the hydrophobic dye boron dipyrromethane (BODIPY), this material can act as a dual-responsive nanoplatform for cells imaging. 2-Chloro-3',4'-dihydroxyacetophenone (CCDP)-quaternized-poly(dimethylaminoethyl methacrylate-co-N-isopropylacrylamide) [C-PDN] was cross-linked with BODIPY and 4-chlorophenyl boronic acid (BA)-quaternized-poly(ethylene glycol)-g-poly(dimethylaminoethyl methacrylate-co-N-isopropylacrylamide) [BB-PPDN]...

Thermoanaerobacterium saccharolyticum has been engineered to produce ethanol at ∼90% theoretical yield and titer of 70 g/L. Its ethanol-producing ability has drawn attention to its metabolic pathways, which could potentially be transferred to other organisms of interest. Here we report that the iron-containing AdhA is important for ethanol production in the high-ethanol strain of T. saccharolyticum (LL1049). A single-gene deletion of adhA in LL1049 reduced ethanol production by ∼50%, whereas multiple gene deletions of all annotated alcohol dehydrogenases except adhA and adhE did not affect ethanol production...

A fluorescent dye and a photothermal agent were grafted onto a cationic polymer for rapid and simple bacteria detection in liquid and solid phase based fluorescence on/off. The integrated poly(vinylpyrrolidone) (PVP) backbone with catechol and bromoethane moieties possesses unique optical properties due to the presence of boron dipyrromethane (BODIPY) and near infared NIR-responsive IR825 (F-PVP). The cationic segments showed distinct fluorescence quenching patterns after interaction with gram-positive and gram-negative bacteria via polyion complex interactions...

Regional surveys were carried out in different parts of North West Pakistan among domestic animals (N=57,921) including pets and livestock identifying cases of traumatic myiasis (n=1037). A total of four surveys focused general livestock population during Eid ul Adha (Eid surveys; incidence=1.21%) while another four surveys (Miscellaneous surveys; incidence=7.34%) targeted animal population brought to veterinary hospitals and dispensaries. Timeframe spanned four years from 2012 to 2015. Maggots were sampled and location of the wound was recorded for each host...

Freshwater mussels (Bivalvia, Unionida) fulfil important ecosystem functions and are one of the most threatened freshwater taxa globally. Knowledge of freshwater mussel diversity, distribution and ecology in Peninsular Malaysia is extremely poor, and the conservation status of half of the species presumed to occur in the region has yet to be assessed. We conducted the first comprehensive assessment of Peninsular Malaysia's freshwater mussels based on species presence/absence and environmental data collected from 155 sites spanning all major river catchments and diverse habitat types...

The optimization of synthetic pathways is a central challenge in metabolic engineering. OptSSeq (Optimization by Selection and Sequencing) is one approach to this challenge. OptSSeq couples selection of optimal enzyme expression levels linked to cell growth rate with high-throughput sequencing to track enrichment of gene expression elements (promoters and ribosome-binding sites) from a combinatorial library. OptSSeq yields information on both optimal and suboptimal enzyme levels, and helps identify constraints that limit maximal product formation...

OBJECTIVES: To investigate the roles of adhS, which encodes the AdhS subunit of membrane-bound alcohol dehydrogenase (mADH) in Gluconobacter oxydans DSM2003, and to rationally improve mADH activity. RESULTS: adhS was identified and overexpressed in G. oxydans DSM2003. Its overexpression promoted the AdhA subunit which serves as the primary dehydrogenase transfer from the periplasmic space to the periplasmic surface of the membrane thereby increasing the amount of active mADH and thus enhancing mADH activity up to 1...

Biofuel offers a promising solution to the adverse environmental problems and depletion in reserves of fossil fuels. Higher alcohols including 3-methyl-1-butanol were paid much more attention as fuel substitute in recent years, due to its similar properties to gasoline. In the present work, 3-methyl-1-butanol production in engineered Corynebacterium glutamicum was studied. α-Ketoisovalerate decarboxylase gene (kivd) from Lactococcus lactis combined with alcohol dehydrogenase gene (adh2, adhA, and adh3) from three organisms were overexpressed in C...
