In Vietnam, intensive shrimp farms heavily rely on a wide variety of antibiotics (ABs) to treat animals or prevent disease outbreak. Potential for the emergence of multi-resistant bacteria is high, with the concomitant contamination of adjacent natural aquatic habitats used for irrigation and drinking water, impairing in turn human health system. In the present study, quantification of AB multi-resistant bacteria was carried out in water and sediment samples from effluent channels connecting a shrimp farming area to the Vam Co River (Long An Province, Vietnam)...

BACKGROUND: Pleural infection is a common complication of pneumonia associated with high mortality and poor clinical outcome. Treatment of pleural infection relies on the use of broad-spectrum antibiotics, since reliable pathogen identification occurs infrequently. We performed a feasibility interventional clinical study assessing the safety and significance of ultrasound (US)-guided pleural biopsy culture to increase microbiological yield. In an exploratory investigation, the 16S rRNA technique was applied to assess its utility on increasing speed and accuracy versus standard microbiological diagnosis...

INTRODUCTION: Pakistan has one of the highest burdens of pneumococcal diseases in the world, but unfortunately studies in this demanding research area are limited in the region. Pneumococcal surface protein A (PspA) is the next generation pneumococcal vaccine candidate as the protein locates on the Streptococcus pneumoniae surface. Its gene, pspA, might be encoded by all pneumococci, and the protein has proven immunogenicity. The molecular characterization of PspA, pneumococcal serotype distribution and antibiotic susceptibility are important for regional diversity studies...

We report a case of Hodgkin's lymphoma presenting as an endobronchial mass in a 40-year-old man with history of 8 months of non-specific symptoms like cough, fatigue and weight loss. Initially he was treated with broad-spectrum antibiotics for suspicion of pneumonia without recovery. Radiographic work-up showed cavitary consolidation of the upper lobe of the left lung, followed by bronchoscopy which showed obstructing mass of the upper lobe of the left lung mimicking primary lung carcinoma. Immunohistochemical staining of the specimen was suggestive of Hodgkin's lymphoma...

Streptococcus pneumoniae is a leading cause of pneumonia and a significant economic burden. Antibiotic-resistant S. pneumoniae has become more prevalent in recent years and many pneumonia cases are caused by S. pneumoniae that is resistant to at least one antibiotic. The ubiquitin ligase natural killer lytic-associated molecule (NKLAM/RNF19b) plays a role in innate immunity and studies using NKLAM-knockout (NKLAM-KO) macrophages have demonstrated that NKLAM positively affects the transcriptional activity of STAT1...

BACKGROUND: Bacterial contamination of cord blood (CB) represents a safety risk for transplantation patients. CB sterility testing at Canadian Blood Services' Cord Blood Bank is performed using a 1:1 mix of CB-derived plasma and red blood cells (RBCs). Culture bottles of an automated culture system, which lack antimicrobial neutralization properties, are used for bacterial screening of CB. This process is unsuitable for CB-containing antibiotics, potentially resulting in false-negative results...

The plasmid-located colistin resistance gene ( mcr - 1 ) confers low-level resistance to colistin, a last-line antibiotic against multidrug-resistant Gram-negative bacteria. Current EUCAST/CLSI recommendations require the use of a broth microdilution (BMD) method in cation-adjusted Mueller-Hinton (CA-MH) for colistin susceptibility testing, but approximately 15% of all MCR-1-producers classify as sensitive in this medium. Here we report on an improved calcium-enhanced Mueller-Hinton (CE-MH) medium that permits simple and reliable determination of mcr-1 -producing Enterobacteriaceae Colistin susceptibility for 50 mcr-1 -encoding isolates of E...

Objectives: The role of protease-activated receptor 1 (PAR1) in the pathogenesis of pneumonia and sepsis is ambiguous given the existing literature. As PAR1 is classically activated by the coagulation-based protease thrombin and leads to vascular leakage, our hypothesis was that PAR1 blockade with SCH79797 would be therapeutically beneficial in an experimental model of murine Gram-negative pneumonia. Methods: In this study, we administered SCH79797 via the intrapulmonary route 6 h after the establishment of Escherichia coli pneumonia and observed a significant improvement in survival, lung injury, bacterial clearance and inflammation...

OBJECTIVES: The majority of children with community acquired pneumonia (CAP) are primarily evaluated in community hospital emergency departments (EDs); however, studies on the management of pediatric CAP have largely targeted care provided in free-standing children's hospital EDs or inpatient settings. The objectives of this study were to examine whether implementation of a CAP pathway within three community hospital EDs and inpatient units improved process measures related to appropriate laboratory testing and antibiotic prescribing, and to compare performance on these measures between the community hospitals and a free-standing children's hospital...

PURPOSE OF REVIEW: Hospital-acquired and ventilator-associated pneumonia (VAP) are frequent causes of infection among critically ill patients. VAP is the most common hospital-acquired bacterial infection among mechanically ventilated patients. Unfortunately, many of the nosocomial Gram-negative bacteria that cause VAP are increasingly difficult to treat. Additionally, the evolution and dissemination of multi- and pan-drug resistant strains leave clinicians with few treatment options. VAP patients represent a dynamic population at risk for antibiotic failure and under-dosing due to altered antibiotic pharmacokinetic parameters...
