[Q]: Bacterial and viral co-infections of the respiratory tract are life-threatening and present a global burden to the global community. Staphylococcus aureus, Streptococcus pneumoniae, and Streptococcus pyogenes are frequent colonizers of the upper respiratory tract. Imbalances through acquisition of seasonal viruses, e.g., Influenza A virus, can lead to bacterial dissemination to the lower respiratory tract, which in turn can result in severe pneumonia. In this review, we summarize the current knowledge about bacterial and viral co-infections of the respiratory tract and focus on potential experimental models suitable for mimicking this disease. Transmission of IAV and pneumonia is mainly modeled by mouse infection. Few studies utilizing ferrets, rats, guinea pigs, rabbits, and non-human primates are also available. The knowledge gained from these studies led to important discoveries and advances in understanding these infectious diseases. Nevertheless, mouse and other infection models have limitations, especially in translation of the discoveries to humans. Here, we suggest the use of human engineered lung tissue, human ex vivo lung tissue, and porcine models to study respiratory co-infections, which might contribute to a greater translation of the results to humans and improve both, animal and human health.

[Q]: Food security in the Middle East is directly affected by a challenging combination of ongoing destructive conflicts, a global economic downturn, widespread poverty, high population growth, corruption, intolerance, and the potentially damaging consequences of climate change. Many Arab countries demonstrate nearly all the features of those countries classified as poor, less developed, or failing to achieve the eight Millennium Goals. Even the economies of the richer oil-exporting countries in the Region have been seriously damaged by the downturn in oil and gas prices as new sources come on stream elsewhere and demand falls as a result of renewable sources of energy becoming available. Climate change predictions for the Region are worrisome even if most of the environmental commitments made by countries at the UN Climate Change Conference in Paris at the end of 2015 are delivered. Large parts of the Region already suffer from periods of extreme temperatures and shortages of fresh water, so harsher conditions of higher temperatures and weather extremes pose special problems for inhabitants and policymakers, with heightened geopolitical risks and uncertainties. Agriculture is especially vulnerable. Modern agricultural technologies with improved cultivars and livestock breeds must displace poor agricultural and pastoral practices. Larger-scale, bettercapitalised production units are required with policy shifts to remove marketdistorting subsidies, tariffs, and other regulatory impedances. Agricultural "roadmaps" are needed to encourage the most appropriate crops and maintain livestock in the most appropriate places. The trading of meat, dairy products and many types of crops to water-poor regions can be regarded as an efficient way to 261 redistribute water. In unsettled times, food security requires protection of foodproducing, food-processing, and food-distribution industries are protected along with research and development facilities, and the maintenance of skilled personnel. There are doubts as to whether agencies of the United Nations, other international agencies, donor countries and charities are able to provide adequate humanitarian aid and humanitarian intervention to enable safeguarding of displaced peoples and ensuring the resumption of normal peaceful conditions essential for food security to be guaranteed. Promises of aid funds must become reality, followed by the establishment of functional supply and transport networks, and rapid transition to self-reliance thereafter. Food security and social stability are inextricably linked. The solution to the food-security problems in the Region ultimately lies in the actions of governments, businesses and individuals. Governments need embedded scientific and technological expertise, strong civil-society institutions, integrity, and a particular focus on high-quality education.

[Q]: Bats are known reservoirs for numerous emerging infectious diseases, occupy unique ecological niches, and occur globally except for Antarctica. Given their impact on human and agricultural health, it is critical to understand the mechanisms underlying immunocompetence in this reservoir host. To date, few studies have examined immune function in the Order Chiroptera, particularly among natural colonies of bats. The phytohemagglutinin (PHA) skin test has been widely used to measure delayed-type cellular immune response in a wide variety of vertebrates, and has been routinely employed in immunoecological studies. Although this test is frequently described as a measure of T cell proliferation, recent studies indicate it may represent a combination of immune responses. In mammals, the immune response is differentially, temporally and spatially regulated, therefore, we characterized the infiltrating leukocyte response to the PHA skin test in bats by examining a time-series of histological sections from PHA and saline injection areas in 41 Brazilian free-tailed bats (Tadarida brasiliensis). Results suggest that bats exhibit diverse leukocyte traffic within 6 h, and up to 24 h following subcutaneous PHA injection. There was a significant presence of lymphocytes and neutrophils, as well as eosinophils, basophils, and macrophages observed in the PHA-injected tissues, compared with saline-injected control tissues. We observed a highly significant negative correlation between the number of lymphocytes and neutrophils in PHA-injected tissue, with peak lymphocyte response at 12 h, and peak neutrophil response at 24 h post-injection. These results indicate substantial variation in the immune response of individuals, and may aid our understanding of disease emergence in natural populations of bats.
