To investigate the occurrence and molecular features of ESBL-producing and colistin-resistant Escherichia coli isolates recovered from healthy food-producing animals in Pakistan.

A total of 153 E. coli isolates were recovered from 250 faecal samples collected from livestock and poultry. The antibiotic susceptibility, resistant determinants and mobile genetic elements were determined for all the isolates. The clonal relatedness was analysed by MLST. Plasmids harbouring, localization and transferability of mcr-1 gene were carried out by Southern hybridization, S1-PFGE and transconjugation.

Out of 153 E. coli strains, 49.01% isolates were ESBLs producers, whereas 18.95% were resistant to colistin and 84.31% of the isolates. Multidrug resistance was found in 84% of the isolates. The ESBL-producing E. coli in buffaloes, cattle, sheep, goat and broilers faecal samples were 60%, 74%, 54%, 50% and 68%, respectively. Among the ESBLs genes, bla

was the most prevalent group detected in 98.66%, while only mcr-1 o association with MGEs, co-harbouring the virulence factors, as determined in the current study, is a severe threat to livestock and the human community as it has horizontally and food web transferability.

Antimicrobial resistance can be transferred from animals to humans by direct contact or via the food chain and environment. The prevalence and co-occurrence of ESBL and colistin resistance genes from food-producing animals is rare in Pakistan. To our knowledge, this is the first report to find ESBLs and mcr-1-harbouring E. coli from the faecal samples of the healthy food-producing animals in Pakistan. The presence of ARGs in association with MGEs, co-harbouring the virulence factors, as determined in the current study, is a severe threat to livestock and the human community as it has horizontally and food web transferability.Climate change will lead to more frequent and more severe fires in some areas of boreal forests, affecting the distribution and availability of late-successional forest communities. These forest communities help to protect globally significant carbon reserves beneath permafrost layers and provide habitat for many animal species, including forest-dwelling caribou. Many caribou populations are declining, yet the mechanisms by which changing fire regimes could affect caribou declines are poorly understood. We analyzed resource selection of 686 GPS-collared female caribou from three ecotypes and 15 populations in a ~600,000 km2 region of northwest Canada and eastern Alaska. These populations span a wide gradient of fire frequency but experience low levels of human-caused habitat disturbance. We used a mixed-effects modeling framework to characterize caribou resource selection in response to burns at different seasons and spatiotemporal scales, and to test for functional responses in resource selection to burn avaf burns and severely burned areas suggests that caribou will experience increasing winter habitat loss as fire frequency and severity increase. Our results highlight the potential for climate-induced alteration of natural disturbance regimes to affect boreal biodiversity through habitat loss. We suggest that management strategies prioritizing protection of core winter range habitat with lower burn probabilities would provide important climate-change refugia for caribou.Animal migration (round-trip, predictable movements) takes individuals across space and time, bringing them into contact with new communities of organisms. In particular, migratory movements shape (and are shaped by) the costs and risk of parasite transmission. Unfortunately, our understanding of how migration and parasite infection interact has not proceeded evenly. Although numerous conceptual frameworks (e.g. mathematical models) have been developed, most empirical evidence of migration-parasite interactions are drawn from pre-existing empirical studies that were conducted using other conceptual frameworks, which limits our understanding. Here, we synthesise and analyse existing work, and then provide a roadmap for future (especially empirical) studies. First, we synthesise the conceptual frameworks that have been developed to understand interactions between migration and parasites (e.g. migratory exposure, escape, allopatry, recovery, culling, separation, stalling and relapse). Second, we highlight current challenges to studying migration and parasites empirically, and to integrating empirical and theoretical perspectives, particularly emphasizing the challenge of feedback loops. Finally, we provide a guide to overcoming these challenges in empirical studies, using comparative, observational and experimental approaches. Beyond guiding future empirical work, this review aims to inspire stronger collaboration between empiricists and theorists studying the intersection of migration and parasite infection. Such collaboration will help overcome current limits to our understanding of how migration and parasites interact, and allow us to predict how these critical ecological processes will change in the future.The above article, published online on 29 January 2022 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal's Editor in Chief Steve Long, and John Wiley & Sons Ltd. The retraction has been agreed because of an error the authors of the paper detected in the R code they used in running the rates of change (RoC) analysis. It was discovered after publication that the R code used in the analysis only picked a single pollen site for each rainforest region, despite the authors´ intention to reconstruct RoC for each rainforest region based on multiple pollen sites. Accordingly, the conclusions of this manuscript are based only on the RoC of single pollen records from each rainforest region, and so are insufficient for a robust and accurate analysis of RoC for each rainforest. The article pages have been replaced by the Retraction Statement and the article condensed accordingly. REFERENCE Adeleye, M. A., Connor, S. E., Herbert, A., & Haberle, S. G. (2022).

VRK2 is also expressed in the brain; however, its molecular function in the central nervous system is mostly unknown. Many genome-wide association studies (GWASs) have reported that VRK2 is a potential candidate molecule for neuropsychiatric diseases such as schizophrenia in humans. However, the pathophysiological relationship between VRK2 and neuropsychiatric disorders has not been fully investigated. In this study, we evaluated vrk2-deficient (vrk2-/- ) zebrafish and found that vrk2-/- female zebrafish showed aggressive behavior and different social preference compared with control (vrk2+/+ ) zebrafish, with low gamma-aminobutyric acid (GABA) content in the brain and high density of neuronal dendrites when compared to vrk2+/+ zebrafish. These findings suggest that female vrk2-/- zebrafish were indeed a model of malbehavior characterized by aggression and social interaction, which can be attributed to the low levels of GABA content in their brain.Lichen Sclerosus is a chronic-relapsing inflammatory skin disease usually involving the anogenital region lacking a resolutive therapy. Potent to high-potent topical corticosteroids are considered to be the standard first-line treatment. The objective of this preliminary study is to evaluate the efficacy of injecting Hybrid Cooperative Complexes of Hyaluronic Acid (HCC) in the treatment of Vulvar Lichen Sclerosus (VLS). Twenty-female patients (range 21-78 years) with histopathologic diagnosis of lichen sclerosus and good general conditions were enrolled. Patients underwent HCC infiltration every month, for three times. Patients had been assessed at baseline (T0) and after 1 and 6 months from treatment (T1 and T2, respectively). Clinical evaluation was executed in every visit. Itching, burning sensation, pain and dyspareunia were reported by a patient at T0, T1, and at T2. The effectiveness of the treatment on patients' quality life and sexual life was assessed using the Dermatology Life Quality Index (DLQI) at T0 and at T2. During or after the treatment no complications or side-effects were observed. All patients had a significant reduction in most symptoms after 1 and 6 months of HCC treatment. The reduction of patients with itching (p ≤ 0.001), pain (p = 0.031), burning sensation (p = 0.004) at 6 months is significant. The analysis of DLQI scores revealed a significant improvement in patients' quality of life. The DLQI mean score (±SD) at baseline and at follow-up was 5.89 ± 3.68 and 3.42 ± 2.36 (p = 0.002), respectively. Our preliminary study has demonstrated the safety and tolerability of HCC infiltrations in patients with VLS, and the effectiveness of HCC in reducing symptoms and, thus, to improve patient Quality of Life.

To assess readiness among primary public health facilities in Kenya to provide pre-referral antimalarials for severe malaria.

Nine national surveys of randomly selected primary public health facilities undertaken bi-annually between 2017 and 2021 were analysed. The outcomes included the availability of pre-referral antimalarial drugs at the health facilities and health worker knowledge of recommended pre-referral treatment for severe malaria.

A total of 1540 health workers from 1355 health facilities were interviewed. Injectable artesunate was available at 46%, injectable quinine at 7%, and artemether at 3% of the health facilities. None of the facilities had rectal artesunate suppositories in stock. A total of 960 (62%) health workers were trained on the use of injectable artesunate. 73% of the health workers who had ever referred a child with severe malaria were aware that artesunate was the recommended treatment, 49% said that intramuscular injection was the preferred route of administration, and 60%) monitoring of the entire referral process.The interest in potentiality and functionality of probiotic yeasts from fermented foods has increased drastically over the years. In many fermented foods and beverages, lactic acid bacteria and yeasts exist synergistically by stimulating their growth and survival. Probiotic strains of lactic acid bacteria are more widely studied than potential probiotic yeasts. Saccharomyces cerevisiae variety boulardii is the only commercialized probiotic yeast, which are extensively studied. This review article provides information on the presence of potential probiotic yeasts in some traditional fermented foods and beverages.Effective conservation requires understanding the processes that determine population outcomes. Too often, we assume that protected areas conserve wild populations despite evidence that they frequently fail to do so. Without large-scale studies, however, we cannot determine what relationships are the product of localized conditions versus general patterns that inform conservation more broadly. Leopards' (Panthera pardus) basic ecology is well studied but little research has investigated anthropogenic effects on leopard density at broad scales. We investigated the drivers of leopard density among 27 diverse protected areas in northeastern South Africa to understand what conditions facilitate abundant populations. We formulated 10 working hypotheses that considered the relative influence of bottom-up biological factors and top-down anthropogenic factors on leopard density. Using camera-trap survey data, we fit a multi-session spatial capture-recapture model with inhomogenous density for each hypothesis and evaluated support using an information theoretic approach.
