BACKGROUND: Although the burden of infectious diseases has decreased dramatically due to advances in health care, disease prevention and numerous public health efforts and innovations, zoonotic diseases continue to pose a problem in terms of both existing and emerging diseases. These risks are of particular concern in rural areas, in which there is more contact with animals for occupational and recreational purposes. As a rural and agricultural state, South Dakota has a large percentage of its population at risk of exposure to zoonotic diseases through their substantial contact time with animals...

Rotavirus (RV) is highly endemic inside and outside hospital-settings. Immunocompromised children and adults are at risk of complicated rotavirus gastroenteritis (RVGE), but general rotavirus disease severity in this group remains poorly described and rotavirus testing is not routinely performed beyond infancy. We assessed rotavirus disease among immunocompromised hospitalized patients. METHODS: Rotavirus infections at a Dutch tertiary-care centre were identified from 5-year laboratory records...

Due to the close genetic background, high similarity of physiology, and susceptibility to infectious and metabolic diseases with humans, rhesus macaques have been widely used as an important animal model in biomedical research, especially in the study of vaccine development and human immune-related diseases. In recent years, high-throughput sequencing based immune repertoire sequencing (IR-SEQ) has become a powerful tool to study the dynamic adaptive immune responses. Several previous studies had analyzed the responses of B cells to HIV-1 trimer vaccine or T cell repertoire of rhesus macaques using this technique, however, there are little studies that had performed a comprehensive analysis of immune repertoire of rhesus macaques, including T and B lymphocytes...

Transmissibility is the defining characteristic of infectious diseases. Quantifying transmission matters for understanding infectious disease epidemiology and designing evidence-based disease control programs. Tracing individual transmission events can be achieved by epidemiological investigation coupled with pathogen typing or genome sequencing. Individual infectiousness can be estimated by measuring pathogen loads, but few studies have directly estimated the ability of infected hosts to transmit to uninfected hosts...

Cytokines are known to play important roles in a wide range of pathologic conditions spanning all organ systems in every species studied. As our knowledge of the physiology of individual cytokines expands and our ability to measure multiple cytokines in smaller biological samples increases, we gain more insight into the significance and function of each cytokine and the importance of cytokine networks. Previous studies that reported measurements of cytokine concentrations from serum or plasma in dogs with infectious, autoimmune, metabolic, endocrine, and neoplastic diseases yield an appreciation for the complexity of cytokine control and potential applications for cytokine measurements in the diagnosis, prognosis, and therapy of a variety of disease conditions...

Brucellosis is an infectious and contagious disease that profoundly impacts public health. However, in many countries, disease prevention is restricted to the vaccination of calves, and there is no prophylactic strategy for pregnant heifers and cows. The aim of this study was to evaluate the safety of the rough strain vaccine against brucellosis in pregnant cattle. Crossbred cows (N = 96) at three gestational periods (early, mid, or late pregnancy) were randomly allocated into the vaccine treatment group or to the control group...

Poliovirus (PV) is the causative agent of poliomyelitis, a crippling human disease known since antiquity. PV occurs in two distinct antigenic forms, D and C, of which only the D form elicits a robust neutralizing response. Developing a synthetically produced stabilized virus-like particle (sVLP)-based vaccine with D antigenicity, without the drawbacks of current vaccines, will be a major step towards the final eradication of poliovirus. Such a sVLP would retain the native antigenic conformation and the repetitive structure of the original virus particle, but lack infectious genomic material...

Epigenetic regulation is based on a network of complexes that modulate the chromatin character and structure of the genome to impact gene expression, cell fate, and development. Thus, epigenetic modulators represent novel therapeutic targets used to treat a range of diseases, including malignancies. Infectious pathogens such as herpesviruses are also regulated by cellular epigenetic machinery, and epigenetic therapeutics represent a novel approach used to control infection, persistence, and the resulting recurrent disease...

OBJECTIVES: Shotgun sequencing in increasingly applied in clinical microbiology for unbiased culture-independent diagnosis. While software solutions for metagenomics proliferate, integration of metagenomics in clinical care, requires method standardisation and validation. Virtual metagenomics samples could underpin validation by substituting real samples and thus we sought to develop a novel solution for simulation of metagenomics samples based on user-defined clinical scenarios. METHODS: We designed the Microbial Metagenomics Mock Scenario-based Sample Simulation (M3S3) workflow, which allows users to generate virtual samples from raw reads or assemblies...

Solid organ transplant (SOT) recipients are especially at risk of developing infections by multidrug resistant (MDR) Gram-negative bacilli (GNB), as they are frequently exposed to antibiotics and the healthcare setting, and are regulary subject to invasive procedures. Nevertheless, no recommendations concerning prevention and treatment are available. A panel of experts revised the available evidence; this document summarizes their recommendations: (1) it is important to characterize the isolate's phenotypic and genotypic resistance profile; (2) overall, donor colonization should not constitute a contraindication to transplantation, although active infected kidney and lung grafts should be avoided; (3) recipient colonization is associated with an increased risk of infection, but is not a contraindication to transplantation; (4) different surgical prophylaxis regimens are not recommended for patients colonized with carbapenem-resistant GNB; (5) timely detection of carriers, contact isolation precautions, hand hygiene compliance and antibiotic control policies are important preventive measures; (6) there is not sufficient data to recommend intestinal decolonization; (7) colonized lung transplant recipients could benefit from prophylactic inhaled antibiotics, specially for Pseudomonas aeruginosa; (8) colonized SOT recipients should receive an empirical treatment which includes active antibiotics, and directed therapy should be adjusted according to susceptibility study results and the severity of the infection...

One of the most pressing contemporary health care challenges consists in rethinking antibiotic use to contrast the increase of multidrug resistant bacteria. Drawing on an ethnographic fieldwork in an Intensive Care Unit that adopts a nonconforming policy of antibiotic stewardship, this article analyzes doctor-doctor interaction concerning infectious disease diagnosis and antibiotic treatment. By analyzing examples of medical decision-making from a corpus of video-recorded morning briefings, we focus on physicians' stance-taking toward the ward's nonconforming policy and illustrate how it is contingently situated along a continuum from strong commitment to overt resistance...

Enrofloxacin (EF) is a veterinary drug for respiratory, gastrointestinal and urinary tract infections. Parenteral administration at doses higher than the manufacturer recommended dosage has induced cartilage lesions in juvenile mammals and poultry. In elasmobranchs EF is commonly used for the treatment of infectious diseases, however only one study has been performed previously to evaluate pharmacokinetics and the potential chondrotoxicity of a fluoroquinolone in adult skates. In present study juvenile lesser spotted dogfish (Scyliorhinus canicula, Linnaeus, 1758) were treated with low (LD, 5mg/kg) and high dose (HD, 10mg/kg) of EF daily via intramuscular injection for 15 consecutive days, as indicated in a recognized treatment...

In this report, we discuss an unusual case of pulmonary lymphomatoid granulomatosis (LYG), a rare form of angiocentric and angiodestructive lymphoproliferative disorder. This disease is thought to be caused by Epstein-Barr virus-induced lymphoproliferation. A 39-year-old male with no signi ficant past medical history presented with flu-like symptoms. Upon further evaluation, laboratory studies noted pancytopenia, and a chest X-ray showed bilateral nodular densities. A computerized tomography (CT) scan demonstrated bilateral pulmonary nodules and splenomegaly...

Canine parvovirus (CPV) is an important and highly prevalent pathogen of dogs that causes acute hemorrhagic enteritis disease. Here, we describe a rapid method for the construction and characterization of a full-length infectious clone (rCPV) of CPV. Feline kidney (F81) cells were transfected with rCPV incorporating an engineered EcoR I site that served as a genetic marker. The rescued virus was indistinguishable from that of wild-type virus in its biological properties.

PURPOSE: Acute diverticulitis (AD) is a highly prevalent disease in Spain. Its chronic-recurrent appearance and high rate of relapse mean that it has a major epidemiological and economic impact on our health system. In spite of this, it has not been studied in any great depth. Reassessing its etiopathology, recent studies have observed that it is an inflammatory disease-not, as classic theories had postulated, an infectious one. In the light of these findings, the suitability of antibiotics for its treatment has been reconsidered...

Regulated erroneous protein translation (adaptive mistranslation) increases proteome diversity and produces advantageous phenotypic variability in the human pathogen Candida albicans. It also increases fitness in the presence of fluconazole, but the underlying molecular mechanism is not understood. To address this question, we evolved hypermistranslating and wild-type strains in the absence and presence of fluconazole and compared their fluconazole tolerance and resistance trajectories during evolution. The data show that mistranslation increases tolerance and accelerates the acquisition of resistance to fluconazole...
