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...

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...

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...

A previously healthy 66-year-old woman living in the Mid-Atlantic USA presented to the hospital with lethargy, ataxia and slurred speech. 2 weeks prior she had removed a tick from her right groin. She reported malaise, fevers, diarrhoea, cough and a rash. Physical examination revealed a maculopapular rash on her chest, and lung auscultation revealed bi-basilar rales. Laboratory tests were remarkable for hyponatraemia, leucopenia and thrombocytopenia. Chest X-ray demonstrated bilateral pleural effusions with pulmonary oedema...

BACKGROUND: Vitamin E has influenced the immune system in laboratory studies. Dozens of animal experiments have found that vitamin E offered protection against infections caused by viruses and bacteria. Previously, significant heterogeneity was found in the effect of vitamin E supplementation on pneumonia in humans. The aim of this study was to examine how the effect of vitamin E on pneumonia risk depends on age. METHODS: Secondary analysis of the Alpha-Tocopherol, Beta-Carotene Cancer Prevention study in Finland, 1985-1993, was performed...

Pneumococcal pneumonia remains a clear unmet medical need for adults worldwide. Despite advances in vaccine technology, vaccination coverage remains low, putting many people at risk of significant morbidity and mortality. The herd effect seen with paediatric vaccination is not enough to protect all older and vulnerable people in the community, and more needs to be done to increase the uptake of pneumococcal vaccination in adults. Several key groups are at increased risk of contracting pneumococcal pneumonia, and eligible patients are being missed in clinical practice...

Community-acquired pneumonia is a major public health problem worldwide. In recent years, there has been an increase in the frequency of resistance to the antimicrobials such as β-lactams or macrolides which have habitually been used against the causative pathogens. Solithromycin, a next-generation macrolide, is the first fluoroketolide with activity against most of the frequently isolated bacteria in community-acquired pneumonia, including typical and atypical bacteria as well as macrolide-resistant Streptococcus pneumoniae...

OBJECTIVE: Red cell distribution width (RDW) is associated with mortality in patients with community-acquired pneumonia (CAP). However, little is known about the effect of changes in RDW during treatment on mortality. Thus, the objective of this study was to evaluate the association between RDW changes and mortality in hospitalized patients with CAP. METHODS: Retrospective analyses were performed using medical records of patients hospitalized for CAP from April 2008 to February 2014...

The Spl proteases are a group of six serine proteases that are encoded on the νSaβ pathogenicity island and are unique to Staphylococcus aureus. Despite their interesting biochemistry, their biological substrates and functions in virulence have been difficult to elucidate. We found that an spl operon mutant of the community-associated methicillin-resistant S. aureus USA300 strain LAC induced localized lung damage in a rabbit model of pneumonia, characterized by bronchopneumonia observed histologically. Disease in the mutant-infected rabbits was restricted in distribution compared to that in wild-type USA300-infected rabbits...

Citrobacter koseri is a motile, gram-negative rod traditionally known to cause infection in individuals with significant comorbidities and immunocompromised status. While most cases represent nosocomial infections, rarely community-acquired infections have been reported. We present a previously healthy man in his 60s with C. koseri pneumonia who was subsequently found to have underlying pulmonary adenocarcinoma, illustrating the need for further investigation for immunodeficiency and/or intrapulmonary pathology...

Pleuromutilins are antibiotics that selectively inhibit bacterial translation and are semisynthetic derivatives of the naturally occurring tricyclic diterpenoid pleuromutilin, which received its name from the pleuromutilin-producing fungus Pleurotus mutilus Tiamulin and valnemulin are two established derivatives in veterinary medicine for oral and intramuscular administration. As these early pleuromutilin drugs were developed at a time when companies focused on major antibacterial classes, such as the β-lactams, and resistance was not regarded as an issue, interest in antibiotic research including pleuromutilins was limited...
