Porcine reproductive and respiratory syndrome virus (PRRSV) infection was diagnosed in 6 Göttingen minipigs (Sus scrofa domestica) with severe interstitial pneumonia. The virus was defined as a North American (NA) subtype virus, which is common in the commercial pig population and might be derived from a widely used attenuated live-virus vaccine in Europe. The ORF5 sequence of the isolated PRRSV was 98% identical to the vaccine virus. The affected pigs were part of a lung transplantation model and received tacrolimus and steroids as well as irradiation or CD8 antibody for immunosuppression...

Primary ciliary dyskinesia (PCD) is a rare genetic disorder caused by structural and/or functional impairment of cilia throughout the whole body. Early diagnosis of PCD is important for the prevention of long‑term sequelae, however early diagnosis is a challenge due to the phenotypic heterogeneity of PCD. In the current study, the patient with PCD was diagnosed at nine years old following several efforts to control intractable airway symptoms. The patient experienced a chronic productive cough beginning in early childhood and had multiple episodes of pneumonia and otitis media with effusion and sinusitis...

Streptococcus suis is a previously neglected, newly emerging multidrug-resistant zoonotic pathogen. Mobile genetic elements (MGEs) play a key role in intra- and interspecies horizontal transfer of antimicrobial resistance (AMR) determinants. Although, previous studies showed the presence of several MGEs, a comprehensive analysis of AMR-associated mobilome as well as their interaction and evolution has not been performed. In this study, we presented the AMR-associated mobilome and their insertion hotspots in S...

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory tract infections in infants and young children. There are no licensed RSV vaccines available, and the few treatment options for high-risk individuals are either extremely costly or cause severe side effects and toxicity. Immunomodulation mediated by a novel formulation consisting of the toll-like receptor 3 agonist poly(I:C), an innate defense regulator peptide and a polyphosphazene (P-I-P) was evaluated in the context of lethal infection with pneumonia virus of mice (PVM)...

Health care associated infections are the most frequent adverse event accompanying healthcare delivery worldwide. Of these, respiratory tract infections, including ventilator-associated pneumonia (VAP), have been recognized as the most common infections in acute hospitals. Sparse anecdotal and epidemiologic data from intensive care units (ICU) and infectious diseases physicians, as well as several publications in this field, suggest that the etiology of VAP in Georgia is most likely Klebsiella pneumoniae. This review article discusses the challenges of infection control in the Georgian health care system, with a focus on VAP...

Although community-acquired pneumonia remains a major public health problem, murine models of bacterial pneumonia have recently facilitated significant preclinical advances in our understanding of the underlying cellular and molecular pathogenesis. In vivo mouse models capture the integrated physiology and resilience of the host defense response in a manner not revealed by alternative, simplified ex vivo approaches. Several methods have been described in the literature for intrapulmonary inoculation of bacteria in mice, including aerosolization, intranasal delivery, peroral endotracheal cannulation under 'blind' and visualized conditions, and transcutaneous endotracheal cannulation...

In 2015, a novel influenza A(H1N1) virus was isolated from a boy in China who had severe pneumonia. The virus was a genetic reassortant of Eurasian avian-like influenza A(H1N1) (EA-H1N1) virus. The hemagglutinin, neuraminidase, and matrix genes of the reassortant virus were highly similar to genes in EA-H1N1 swine influenza viruses, the polybasic 1 and 2, polymerase acidic, and nucleoprotein genes originated from influenza A(H1N1)pdm09 virus, and the nonstructural protein gene derived from classical swine influenza A(H1N1) (CS H1N1) virus...

A known case of primary Sjogren's syndrome with chronic kidney disease presented with respiratory symptoms and subsequent altered sensorium. Chest imaging suggested cavitating lung lesions in both the lungs. Serum c-ANCA was positive without any upper respiratory tract involvement or active urinary sediments. Treatment with appropriate anti-microbials produced no improvement in the respiratory or neurological parameters. MRI brain revealed tell-tale signs of CNS vascultis. A diagnosis of GPA was made as per European Medical Agency algorithm and the patient was started on immune-suppressants to which there was dramatic response...

Intravenous ceftaroline fosamil (Zinforo™), a prodrug that is rapidly converted to its active metabolite ceftaroline, is approved for use in adults and children (from 2 months of age) with complicated skin and soft tissue infections (cSSTIs) or community-acquired pneumonia (CAP). In several multinational trials, ceftaroline fosamil was an effective and generally well tolerated treatment in adult and paediatric patients with cSSTIs or CAP. In the phase 3 CANVAS trials, ceftaroline fosamil treatment was noninferior to vancomycin plus aztreonam in adults with cSSTIs...

Infections (including sepsis, meningitis, pneumonia and tetanus) stand as a major contributor to neonatal mortality in Haiti (22%). Infants acquire bacteria that cause neonatal sepsis directly from the mother's blood, skin or vaginal tract either before or during delivery. Nosocomial and environmental pathogens introduce further risk after delivery. The absence of cohesive medical systems and methods for collecting information limits the available data in countries such as Haiti. This study seeks to add more information on the burden of severe bacterial infections and their etiology in neonates of Haiti...

Fungal infections are recognized in an increasing number of patients with immunological deficits and are associated with high rates of mortality (Brown et al., 2012a). In this pilot-study, a rapid Real time PCR (fuPCR) was designed for the detection and differentiation of fungal pathogens in clinical specimens of haematological patients. The fuPCR, targeting the internal transcribed spacer region 2 (ITS2) of rDNA region, is comprised of seven multiplex reactions, which were shown to be specific and sensitive for a comprehensive spectrum of clinically relevant fungal species...

BACKGROUND: Global childhood mortality rates remain high. Millennium Development Goal 4 focused efforts on reducing rates by two-thirds between 1990 and 2015. In Ethiopia, child mortality rates dropped 71 % from 1990 to 2015, however it is estimated that 184,000 Ethiopian children die each year. There is limited information about pediatric hospital admissions in Ethiopia. Our aims were to examine the temporal relationship of mortality to admission, describe the demographics, and identify cause mortality of children admitted to the Zewditu Memorial Hospital (ZMH)...

BACKGROUND: Over 300 million patients undergo surgery worldwide each year. Postoperative morbidity - particularly respiratory complications - are most frequent and severe among high-risk patients undergoing major abdominal surgery. However, standard treatments, like physiotherapy or supplemental oxygen, often fail to prevent these. Preliminary research suggests that prophylactic continuous positive airways pressure (CPAP) can reduce the risk of postoperative respiratory complications...

Human metapneumovirus (hMPV) is a paramyxovirus that causes respiratory tract infections ranging from mild upper airway infection to severe pneumonia. Patients with haematological disease, especially haematopoietic stem cell transplantation (HSCT) recipients, are more likely to develop more severe infections. We describe three cases of hMPV infection in HSCT patients. The most reliable diagnostic procedure for hMPV is multiplex ligation-dependent probe amplification (MLPA) on a nasopharyngeal swab. Sensitivity and specificity of MLPA to detect hMPV is high and time to diagnosis is short...

Interferon regulatory factor-7 (IRF-7) is involved in pulmonary infection and pneumonia. Here, a synthetic strategy that combined quantitative structure-activity relationship (QSAR)-based virtual screening and in vitro binding assay was described to identify new and potent mediator ligands of IRF-7 from natural products. In the procedure, a QSAR scoring function was developed and validated using Gaussian process (GP) regression and a structure-based set of protein-ligand affinity data. By integrating hotspot pocket prediction, pharmacokinetics profile analysis and molecular docking calculations, the scoring function was successfully applied to virtual screening against a large library of structurally diverse, drug-like natural products...

Mycoplasma pneumoniae (M. pneumoniae) is an important causative pathogen of community-acquired pneumonia in children. Rapid and reliable laboratory diagnosis of M. pneumoniae infection is important so that appropriate antibiotic treatment can be initiated to reduce the misuse of drugs and resistance rates. Anti-M. pneumoniae immunoglobulin M (IgM) is an indicator of recent primary infection, but can persist for several months after initial infection. It has been suggested that anti-M. pneumoniae immunoglobulin A (IgA) can be a reliable indicator for recent M...
