A major concern of phage therapy is the emergency of phage-resistant mutants. This limitation can be overcome by the combined use of phages and antibiotics. It has been shown that the combination of antibiotics and phages is an alternative that cannot only be effective at reducing bacterial numbers, but also to contribute to the management of resistance levels. However, this view has only been discussed with regard to antibiotic resistance and not to control phage-mutant emergence. In our study we compared not only the resistance of the bacteria to the four antibiotics tested with and without phages addition, but also the resistance to the phages in the presence and absence of antibiotics...

INTRODUCTION: Splenic abscesses are rare in immunocompetent adults. Despite advances in diagnosis and treatment, these abscesses are still potentially life threatening. Various factors have been reported to predispose otherwise immunocompetent adults to splenic abscesses. Splenectomy was once considered the "gold standard" treatment. However, the trend is shifting to a conservative approach. CASE DESCRIPTION: We describe seven cases of splenic abscess in immunocompetent adults, the cause of which ranged from tuberculosis to salmonella and was as rare as Plasmodium vivax...

Infective endocarditis (IE) may be accompanied by the production of a broad spectrum of autoantibodies, including antineutrophil cytoplasmic antibodies (ANCA). ANCA detection creates difficulties in the differential diagnosis of IE, especially in relation to kidney injury, the determination of the mechanism of which is important for choosing a treatment policy and estimating a prognosis. The paper describes a clinical case of a 57-year-old man who was found to have higher proteinase-3 (PR-3) ANCA titers along with the symptoms of anemia, purpura, and kidney injury during his hospitalization; echocardiography revealed vegetation on the aortic valve...

Sepsis and septic shock are common life-threatening pathologies associated with high mortality and substantial costs for healthcare system. Clinical guidelines and bundles for the management of patients with sepsis have recently been updated. Herein, we review the history of sepsis and related conditions definitions from the first consensus conference in 1991 to nowadays, the epidemiologic data resulting from worldwide studies on incidence and mortality, the diagnostic approaches including the microbiological assessment of infection and the use of several prognostic and diagnostic biomarkers and finally we review the main therapeutic measures as the intravenous immunoglobulin therapy and the administration of appropriate antibiotic treatment to provide patients with sepsis a favourable outcome in the antibiotic-resistance era...

OBJECTIVES: The impact of antimicrobial therapy on the outcome of patients with colonized catheters and no bacteraemia has not been assessed. We assessed whether targeted antibiotic therapy was related for having poor outcome (PO) in patients with positive cultures of blood drawn through a non-tunneled central venous catheter (CVC) and without concomitant bacteraemia. METHODS: We performed a retrospective study in which we selected adult patients with positive blood cultures drawn through a CVC and negative peripheral vein blood cultures...

Sepsis should be defined as life-threatening organ dysfunction caused by a dys-regulated host response to infection. Continuous renal replacement therapy (CRRT) is one of the methods for the clinical treatment of sepsis. For patients undergoing CRRT, rational antimicrobial therapy is very important for the control of patient's infection. However, during CRRT, there is no clear guideline for the dose adjustment of antibiotics. In this paper, we analyzed the effect of CRRT combined with antibiotics on sepsis treatment in China and abroad, and discussed its effect on antibiotic clearance, and provided reference for clinical work...

OBJECTIVES: The current clinical standard for local antibiotic depot is polymethylmethacrylate (PMMA) beads. Unfortunately, these are not ideal and negative pressure wound therapy (NPWT) reduces their limited effectiveness. Recently, a chitosan sponge has been shown to be an effective carrier of antibiotics. Since it acts as a delivery vehicle with increased wound contact area instead of an antibiotic depot, it may be more effective. The objectives of this study are to determine if 1) a chitosan sponge would be more effective than PMMA beads as a local antibiotic delivery device and 2) the chitosan sponge remains an effective method of delivery when used in conjunction with NPWT...

Extracellular capsules constitute the outermost layer of many bacteria, are major virulence factors, and affect antimicrobial therapies. They have been used as epidemiological markers and recently became vaccination targets. Despite the efforts to biochemically serotype capsules in a few model pathogens, little is known of their taxonomic and environmental distribution. We developed, validated, and made available a computational tool, CapsuleFinder, to identify capsules in genomes. The analysis of over 2500 prokaryotic genomes, accessible in a database, revealed that ca...

Sexually transmitted infections (STIs) can impair sexual health. Surveillance and study data were used to provide an overview over STIs in Germany. We estimated 3900 new HIV diagnoses in 2015. Of newly diagnosed infections, 57% were attributed to men who have sex with men (MSM). It was further estimated that there were 3200 new HIV infections and 84,700 people living with HIV in 2015. A total of 6834 syphilis infections were recorded in 2015, which corresponds to an increase of 149% since 2009. The incidence in men was 16-times higher than in women...

Firstly described in the 19th century by Sir William Osler, the mycotic aneurysm (MA) is a rare entity characterized by an abnormal arterial dilation, which is potentially fatal, and is associated with the infection of the vascular wall. Elderly patients are mostly involved, especially when risk factors like chronic diseases, immunosuppression, neoplasia, and arterial manipulation are associated. The authors report the case of a young male patient diagnosed with an aortic aneurysm of infectious origin in the presence of repeated negative blood cultures...

Mycobacterium tuberculosis (Mtb) primarily infects lung macrophages. However, recent study has shown that Mtb also infect and persist in dormant form inside the bone marrow mesenchymal stem cells (BM-MSCs) even after successful antibiotic therapy. However, the mechanism(s) by which Mtb survives in BM-MSCs is still not known. Like macrophages, BM-MSCs do not contain a well-defined endocytic pathway, which is known to play a central role in the clearance of internalized mycobacteria. Here, we studied the fate of virulent and avirulent mycobacteria in Sca-1(+)/CD44(+) BM-MSCs...

BACKGROUND: As a novel biomarker of inflammation, procalcitonin (PCT) has proven useful to guide antibiotic therapy in intensive care unit (ICU). However, there are controversial on mortality. The aim of this study was to evaluate the utility of PCT-guided antibiotic therapy in critically ill adults and determine whether studies are sufficient. METHODS: A systematic search in PubMed, Embase and Cochrane was performed. We included only randomized controlled trials which compared the safety and efficacy between PCT-guided or standard antibiotic therapy groups in ICU adults...
