Genome sequencing has become a powerful tool for studying emerging infectious diseases; however, genome sequencing directly from clinical samples (i.e., without isolation and culture) remains challenging for viruses such as Zika, for which metagenomic sequencing methods may generate insufficient numbers of viral reads. Here we present a protocol for generating coding-sequence-complete genomes, comprising an online primer design tool, a novel multiplex PCR enrichment protocol, optimized library preparation methods for the portable MinION sequencer (Oxford Nanopore Technologies) and the Illumina range of instruments, and a bioinformatics pipeline for generating consensus sequences...

Although the recent Zika virus (ZIKV) epidemic in the Americas and its link to birth defects have attracted a great deal of attention, much remains unknown about ZIKV disease epidemiology and ZIKV evolution, in part owing to a lack of genomic data. Here we address this gap in knowledge by using multiple sequencing approaches to generate 110 ZIKV genomes from clinical and mosquito samples from 10 countries and territories, greatly expanding the observed viral genetic diversity from this outbreak. We analysed the timing and patterns of introductions into distinct geographic regions; our phylogenetic evidence suggests rapid expansion of the outbreak in Brazil and multiple introductions of outbreak strains into Puerto Rico, Honduras, Colombia, other Caribbean islands, and the continental United States...

Transmission of Zika virus (ZIKV) in the Americas was first confirmed in May 2015 in northeast Brazil. Brazil has had the highest number of reported ZIKV cases worldwide (more than 200,000 by 24 December 2016) and the most cases associated with microcephaly and other birth defects (2,366 confirmed by 31 December 2016). Since the initial detection of ZIKV in Brazil, more than 45 countries in the Americas have reported local ZIKV transmission, with 24 of these reporting severe ZIKV-associated disease. However, the origin and epidemic history of ZIKV in Brazil and the Americas remain poorly understood, despite the value of this information for interpreting observed trends in reported microcephaly...

Maize lethal necrosis (MLN) has emerged as a serious threat to food security in sub-Saharan Africa. MLN is caused by coinfection with two viruses, maize chlorotic mottle virus (MCMV) and a potyvirus, often sugarcane mosaic virus (SCMV). To better understand dynamics of MLN and to provide insight into disease management, we model the spread of the viruses causing MLN within and between growing seasons. The model allows for transmission via vectors, soil and seeds, as well as exogenous sources of infection. Following model parameterisation, we predict how management affects disease prevalence and crop performance over multiple seasons...

Tetanus, an almost forgotten but serious disease Tetanus is the systemic consequence of a local infection with Clostridium tetani, that produces toxin which spreads in the systemic circulation. In developed countries, it is extremely rare. Women born before 1950 are a group at risk due to lower prevalence of immunisation. This report describes a case of tetanus. The patient is a previously healthy 82-year-old woman. She presented to primary care with a complaint of stiffness in the neck and jaw. A physical exam and basic laboratory tests were normal apart from a slightly increased blood pressure...

REVIEW

Global rollout of the new antituberculosis drug bedaquiline has been slow, in part reflecting concerns about spread of bedaquiline resistance. Acquired resistance to bedaquiline is especially likely in patients with extensively drug-resistant (XDR) tuberculosis. However, the very high mortality rates of patients with XDR not receiving bedaquiline, and promising cohort study results, suggest these patients also have greatest need for the drug. In this Personal View, we argue that resistance concerns should not forestall use of bedaquiline in patients with XDR tuberculosis...

Population density is a key driver of disease dynamics in wildlife populations. Accurate disease risk assessment and determination of management impacts on wildlife populations requires an ability to estimate population density alongside management actions. A common management technique for controlling wildlife populations to monitor and mitigate disease transmission risk is trapping (e.g., box traps, corral traps, drop nets). Although abundance can be estimated from trapping actions using a variety of analytical approaches, inference is limited by the spatial extent to which a trap attracts animals on the landscape...

The spread of neurofibrillary tangle (NFT) pathology through the human brain is a hallmark of Alzheimer's disease (AD), which is thought to be caused by the propagation of "seeding" competent soluble misfolded tau. "TauC3", a C-terminally truncated form of tau that is generated by caspase-3 cleavage at D421, has previously been observed in NFTs and has been implicated in tau toxicity. Here we show that TauC3 is found in the seeding competent high molecular weight (HMW) protein fraction of human AD brain. Using a specific TauC3 antibody, we were able to substantially block the HMW tau seeding activity of human AD brain extracts in an in vitro tau seeding FRET assay...

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a prevalence of 1 million persons worldwide. The fibrosis spreads from affected alveoli into contiguous alveoli and leads to death by asphyxiation. We previously discovered that the IPF lung harbors fibrogenic mesenchymal progenitor cells (MPCs) that serve as a cell of origin for disease-mediating myofibroblasts. In a prior genomewide transcriptional analysis, we found that IPF MPCs displayed increased expression of S100 calcium-binding A4 (S100A4), a protein linked to cancer cell proliferation and invasiveness...

Pituitary adenomas represent one of the most common types of intracranial tumors, accounting for 10-20% of intracranial tumors. While their macroscopic appearance and anatomical location are relatively homogeneous, pituitary tumors differ widely, generating a variety of neurological and endocrine clinical sequelae. Treatment options include hormone suppressive medical therapy, microscopic or endoscopic neurosurgical resection, radiosurgery, radiation therapy, or observation depending on the biochemical profile and the clinical status of the patient...

The deposition of immune complexes (IC) in tissues induces a "type III hypersensitivity" that results in tissue damage and underlies the pathogenesis of many autoimmune diseases. The neutrophil is the first immune cell recruited into sites of IC deposition and plays a critical role in shaping the overall tissue response. However, the mechanism by which IC initiate and propagate neutrophil infiltration into tissue is not known. Here, using intravital multiphoton joint imaging of IC-induced arthritis in live mice, we found that the complement C5a receptor (C5aR) was the key initiator of neutrophil adhesion on joint endothelium...

INTRODUCTION: Despite meticulous surgery and proper adjuvant treatment, outcome of oral squamous cell carcinoma remains unpredictable. This shows that there may be other factors which should be considered while prognosticating these patients. Many a times there is spread of disease beyond the gross margin which can alter the margin status. We hypothesized that microscopic spread beyond gross disease may portend a poor prognosis. METHOD: This is a retrospective study of prospectively collected data of 1025 treatment naïve oral squamous cell carcinoma patients...

Laron syndrome (LS) is a unique model of congenital IGF-I deficiency. It is characterized by dwarfism and obesity, and is caused by deletion or mutations of the growth hormone receptor (GH-R) gene. It is hypothesized that LS is an old disease originating in Indonesia and that the mutated gene spread to South Asia, the Middle East, the Mediterranean region and South America.

Keith W Jarosinski
Interindividual spread of herpesviruses is essential for the virus life cycle and maintenance in host populations. For most herpesviruses, the virus-host relationship is close, having coevolved over millions of years resulting in comparatively high species specificity. The mechanisms governing interindividual spread or horizontal transmission are very complex, involving conserved herpesviral and cellular proteins during the attachment, entry, replication, and egress processes of infection. Also likely, specific herpesviruses have evolved unique viral and cellular interactions during cospeciation that are dependent on their relationship...

BACKGROUND: An outbreak of Zika virus infection was detected in Singapore in August, 2016. We report the first comprehensive analysis of a national response to an outbreak of Zika virus infection in Asia. METHODS: In the first phase of the outbreak, patients with suspected Zika virus infection were isolated in two national referral hospitals until their serum tested negative for the virus. Enhanced vector control and community engagement measures were deployed in disease clusters, including stepped-up mosquito larvicide and adulticide use, community participation in source reduction (destruction of mosquito breeding sites), and work with the local media to promote awareness of the outbreak...

Animal models of neurodegeneration induced by neuronal expression of truncated tau protein emerge as an important tool for understanding the pathogenesis of human tauopathies and for therapy development. Here we highlight common features of truncated tau models and make a critical assessment of possible pitfalls in their analysis. Particularly, the amount of soluble tau oligomers, which are suspected to be neurotoxic agents participating on the spreading of pathology inside the brain, may be overestimated due to a post-lysis oxidative tau oligomerization...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

The visual system is involved in different ways in migraine. Visual auras are the most common form of migraine aura. It may consist of positive or negative visual symptoms and cortical spreading depression is felt to be the phenomenon that underlies it. Even in migraine without aura, vision it is not totally excluded given that one of the major criteria for the diagnosis of migraine is photophobia. In persistent visual aura, patients refer symptoms defined as visual snow and television static. In retinal migraine unilateral decreased vision or complete visual loss occurs...
