Tsetse flies (Glossina spp.) transmit parasitic African trypanosomes (Trypanosoma spp.), including Trypanosoma congolense, which causes animal African trypanosomiasis (AAT). AAT detrimentally affects agricultural activities in sub-Saharan Africa and has negative impacts on the livelihood and nutrient availability for the affected communities. After tsetse ingests an infectious blood meal, T. congolense sequentially colonizes the fly's gut and proboscis (PB) organs before being transmitted to new mammalian hosts during subsequent feedings...

Recent pandemics and rapidly spreading outbreaks of infectious diseases have illustrated the interconnectedness of the world and the importance of improving the international community's ability to effectively respond. The Centers for Disease Control and Prevention (CDC), building on a strong foundation of lessons learned through previous emergencies, international recognition, and human and technical expertise, has aspired to support nations around the world to strengthen their public health emergency management (PHEM) capacity...

Water on Earth-in our oceans, rivers, lakes, and wetlands-might seem plentiful, but water that is clean and safe enough to drink actually isn't so abundant. Nearly one in ten people still lacks access to safe water worldwide, according to the World Health Organization. In some of the world's most remote and impoverished communities, people live with no taps, showers, flushing toilets, or nearby springs, making it difficult to keep water supplies safe from bacteria, chemicals, and particulates. Moreover, access to clean drinking water isn't just a problem in the developing world; groundwater in developed countries is typically used far more quickly than it is being replenished...

Cystic echinococcosis (CE), a widespread, complex zoonosis, causes chronic disease associated with high morbidity. The pastoral Turkana people of Kenya have one of the highest prevalence rates of CE in the world. Between 1983 and 2015, a CE control program in the Turkana region used ultrasound (US) screening surveys and surgical outreach visits to evaluate CE prevalence and treat those with the disease. As the gold standard modality for diagnosing CE, US reveals a great deal of information about the disease in affected populations...

The identification of host-specific bacterial and viral communities associated with diverse animals has led to the concept of the metaorganism, which defines the animal and all of its associated microbes as a single unit. Here we sequence the viruses found in the gut (i.e., the gut virome) of the marine invertebrate model system, Ciona intestinalis subtype A, in samples collected one year apart. We present evidence for a host-associated virome that is distinct from the surrounding seawater and contains some temporally-stable members...

Access to effective services is imperative to address the many health and mental health disparities that lesbian, gay, bisexual, and transgender (LGBT) people face. This population, however, remains underserved and often ill-served in health care environments. Furthermore, interactions between system- and individual-level dimensions of access create barriers to service engagement. Within much of the extant literature surrounding health care barriers among LGBT people, the rich narratives and varied experiences of LGBT community members from diverse backgrounds have often been excluded...

We describe our ethics-driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis-sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would-be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP) values...

The TRACK-II program is a multi-site, community-based randomized controlled trial evaluating an intervention to assist mothers living with HIV (MLH) in disclosing their HIV status to their young children. Many participants-both mothers and children-reported significant depression and/or suicidal ideation, a phenomenon that presented ethical challenges. This article focuses on participants at one site (Atlanta). Through the vignette of "Jordan," we describe ethical challenges that may arise when faced with the responsibility of maximizing participants' safety while maintaining the boundaries of the researcher role...

The study of life and living organisms and the way in which these interact and organize to form social communities have been central to my career. I have been fascinated by biology, neurology, and neuropathology, but also by history, sociology, and art. Certain current historical, political, and social events, some occurring proximally but others affecting people in apparently distant places, have had an impact on me. Epicurus, Seneca, and Camus shared their philosophical positions which I learned from. Many scientists from various disciplines have been exciting sources of knowledge as well...

Triclosan (TCS) is an emerging organic contaminant in the environment. Here, the anoxic bio-degradation of TCS in microbial fuel cells (MFCs) was explored. It was found that anoxic biodegradation of TCS could be achieved in MFC, and the removal rate of TCS was accelerated after reactor acclimation. After 7 months of operation, 10mg/L TCS could be removed within 8days in MFCs. Fluorescence microscopy results revealed that the microbe cells in the reactors were intact, and the microbes were in active state. Flow cytometry test showed that the proliferation of inoculated microbe was higher in MFC effluent than that in TCS solution...

An increasing amount of carbon-based nanomaterials (CNM) (mostly fullerenes, carbon nanotubes and graphene) has been observed in aquatic systems over the last years. However, the potential toxicity of these CNM on aquatic ecosystems remains unclear. This paper reviews the existing literature on the toxic effects of CNM in aquatic organisms as well as the toxic effects of CNM through influencing the toxicity of other micro-pollutants, and outlines a series of research needs to reduce the uncertainty associated with CNMs toxic effects...

OBJECTIVES: Oral history (OH) and digital storytelling (DST) have been used in a range of ways in public health, including educating populations about health-protecting practices, advocating for improved clinical care and reflecting on public health efforts to combat infectious disease. Yet, these methods are rarely recognized for their potential to contribute to public health research and practice. The aim of this article is to assess how OH and DST have been used in the health fields and to provide examples of ways that these methods have contributed to work in several domains of public health...

Microbiome analyses of soils and microcosm experiments depend on conditions that include sterilization in order to perform experimental manipulation of microbial communities. Still, they should represent conditions close to nature. When using metal contaminated soils, sterilization methods might alter metal availability. Here, four typical metal contaminated substrates were analyzed, representing different contamination histories and soil types. They included two very poor substrates, as they are often found at metal contaminated sites...

In this paper, we explore the increasing activity around labor rights for South African community health workers (CHWs). Contextualizing this activity within broader policy and legal developments, we track the emergence of sporadic mobilizations for decent work (supported by local health activist organizations) and subsequently, the formation of a CHW union. The National Union of Care Workers of South Africa (NUCWOSA) was inaugurated in 2016, hoping to secure formal and secure employment through government and the consequent labor and occupational health protections...

The Amazonian catfish, Panaque nigrolineatus have several physiological adaptions enabling the scraping and consumption of wood (xylivory), facilitating a detritivorous dietary strategy. Composed of lignocellulose, wood is a difficult substrate to degrade and as yet, it is unclear whether the fish obtains any direct nutritional benefits from wood ingestion and degradation. However, there are numerous systems that rely on microbial symbioses to provide energy and other nutritional benefits for host organisms via lignocellulose decomposition...

Cohabitation of microbial communities with the host enables the formation of a symbiotic relationship that maintains homeostasis in the gut and beyond. One prevailing model suggests that this relationship relies on the capacity of host cells and tissues to remain tolerant to the strong immune stimulation generated by the microbiota such as the activation of Toll-like receptor 4 (TLR4) pathways by lipopolysaccharide (LPS). Indeed, gut microbial LPS is thought to be one of the most potent activators of innate immune signaling and an important mediator of the microbiome's influence on host physiology...

Background: Non-communicable diseases (NCDs) kill 40 million people each year. The management of chronic respiratory NCDs such as chronic obstructive pulmonary disease (COPD) is particularly critical in Italy, where they are widespread and represent a heavy burden on healthcare resources. It is thus important to redefine the role and responsibility of respiratory specialists and their scientific societies, together with that of the whole healthcare system, in order to create a sustainable management of COPD, which could become a model for other chronic respiratory conditions...

Background: Methicillin-resistant Staphylococcus aureus (MRSA) infection is associated with increased morbidity, mortality, and financial burdens. Phenotyping methods are used to classify MRSA as either health care MRSA (HA-MRSA) or community-associated MRSA (CA-MRSA). Recent studies suggested the phenotyping methods are not always reliable, based on a lack of concordance with genotyping results. Objective: In this study, concordance of classification methods based on clinical characteristics or antibiotic susceptibility compared to the gold standard genotyping was assessed in the classification of MRSA...

INTRODUCTION AND HYPOTHESIS: This formative qualitative follow-up study addresses validity concerns in the Dabat Incontinence and Prolapse (DABINCOP) study, which aimed to determine the prevalence of pelvic floor disorders in north-west Ethiopia. A pilot study using a questionnaire validated by pelvic exam showed severe underreporting of clinically relevant pelvic organ prolapse (POP). The objective of the follow-up study was to explore the reasons behind the underreporting and to gather information to strengthen the sensitivity and local relevance of the questionnaire to be employed in the main study...
