The treatment of leishmaniasis still relies on drugs with potentially serious adverse effects. Herein, we tested a topical formulation of bacterial cellulose (BC) membranes containing Diethyldithiocarbamate (DETC), a superoxide dismutase 1 inhibitor. Leishmania-infected macrophages exposed to BC-DETC resulted in parasite killing, without pronounced toxic effects to host cells. This outcome was associated with lower SOD1 activity and higher production of superoxide and cytokine mediators. Topical application of BC-DETC significantly decreased lesion size, parasite load and the inflammatory response at the infection site, as well as the production of both IFN-γ and TNF...

The sacroiliitis accounts for about 1.5% - 10% of all cases of septic arthritis and it is strongly associated with gynaecological infections, pelvic trauma or drug abuse (3.4% - 12.8% of cases occur during the postpartum period). Early diagnosis is difficult because the symptoms are nonspecific in pregnancy and in the postpartum period, making the delay of treatment a serious risk of irreversible damage to the joint and development of post-infectious complications. The authors describe the case of a 37-year-old puerperal woman presented to hospital, weeks after urgent caesarean section, with endometritis, post-anesthetic epidural hematoma and secondary infectious postpartum sacroiliitis...

Combating antimicrobial resistance is one of the most serious public health challenges facing society today. The development of new antibiotics or alternative techniques that can help combat antimicrobial resistance is being prioritised by many governments and stakeholders across the globe. Antimicrobial photodynamic therapy is one such technique that has received considerable attention but is limited by the inability of light to penetrate through human tissue, reducing its effectiveness when used to treat deep-seated infections...

BACKGROUND: Septic arthritis is a serious joint disease often caused by Staphylococcus aureus (S. aureus). Receptor for Advanced Glycation End products (RAGE) has an important role in several infections. We sought to investigate the role of RAGE in staphylococcal septic arthritis and sepsis in mice. METHODS: Wild-type (WT) and RAGE deficient (RAGE-/-) mice were intra-articularly or intravenously inoculated with an arthritic or septic dose of S. aureus LS-1 strain...

BACKGROUND: In heroin injectors, there have been a number of outbreaks caused by spore-forming bacteria, causing serious infections such as anthrax or botulism. These are, most likely, caused by injecting contaminated heroin, and our aim was to develop a filter that efficiently removes these bacteria and is also likely to be acceptable for use by people who inject drugs (i.e. quick, simple and not spoil the hit). METHODS: A prototype filter was designed and different filter membranes were tested to assess the volume of liquid retained, filtration time and efficiency of the filter at removing bacterial spores...

The therapeutic use of bacteriophages has seen a renewal of interest blossom in the last few years. This reversion is due to increased difficulties in the treatment of antibiotic-resistant strains of bacteria. Bacterial resistance to antibiotics, a serious problem in contemporary medicine, does not implicate resistance to phage lysis mechanisms. Lytic bacteriophages are able to kill antibiotic-resistant bacteria at the end of the phage infection cycle. Thus, the development of phage therapy is potentially a way to improve the treatment of bacterial infections...

Carbapenems are a class of last-resort antibiotics; thus, the increase in bacterial carbapenem-resistance is a serious public health threat. Acinetobacter baumannii is one of the microorganisms that can acquire carbapenem-resistance; it causes severe nosocomial infection, and is notoriously difficult to control in hospitals. Recently, a machine-learning approach was first used to analyze the genome sequences of hundreds of susceptible and resistant A. baumannii strains, including those carrying commonly acquired resistant mechanisms, to build a classifier that can predict strain resistance...

BACKGROUND: Propionibacterium (P) acnes infection of the shoulder after arthroplasty is a common and serious complication. Current detection methods for P acnes involve anaerobic cultures that require prolonged incubation periods (typically 7-14 days). We have developed a polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) approach that sensitively and specifically identifies P acnes in tissue specimens within a 24-hour period. METHODS: Primers were designed to amplify a unique region of the 16S rRNA gene in P acnes that contained a unique HaeIII restriction enzyme site...

Multidrug-resistant bacterial infections of the gastrointestinal tract pose a serious public health concern. High levels of antibiotic drug resistance, along with the potential for antibiotics to precipitate disease or alter the gut microbiome has prompted research into alternative treatment methods. Evidence suggests that bacteriophage therapy delivered per os may be well-suited to target such infections. Areas covered: Herein, we discuss the specific advantages and challenges of using orally administered phage therapy...

Potentially life-threatening infections require immediate antibiotic therapy. Most early stage antibiotic treatment for these infections is empirical, that is, covering a range of possible target bacteria while awaiting culture results. Empirical antibiotic regimens need to reflect the epidemiology of most likely causative bacteria, type of infection and patient risk factors. Summary data from relevant isolates in similar patients help to identify appropriate empirical regimens. At present, such data are mostly presented as hospital or other aggregate antibiograms, showing antimicrobial susceptibility testing results by bacterial species...

The available literature data give evidence that viral infection is the main cause underlying the development of inflammatory nasopharyngeal pathology in the children. According to ICD-10, nether acute nor chronic adenoiditis should be considered as a self-consistent nosological entity. Acute adenoiditis is usually regarded as a form of acute nasopharyngitis (J02) or acute respiratory viral infection (J06.9) whereas chronic adenoiditis is commonly referred to as representing other chronic diseases of the tonsils and adenoids (J 35...

In the course of influenza A virus (IAV) infections, a secondary bacterial infection frequently leads to serious respiratory conditions provoking high hospitalization and death tolls. Although abundant pro-inflammatory responses have been reported as key contributing factors for these severe dual infections, the relative contributions of cytokines remain largely unclear. In the current study, mathematical modelling based on murine experimental data dissects IFN-γ as a cytokine candidate responsible for impaired bacterial clearance, thereby promoting bacterial growth and systemic dissemination during acute IAV infection...

There are 264 primary immunodeficiencies (PIDs), most of which are rare. They are caused by complement deficiencies, defects in phagocyte function, impaired T-cell function, and/or impaired B-cell function with antibody deficiencies. Most patients with PIDs will present, at varying ages, with frequent infections. These infections can be common respiratory tract infections such as otitis media or pneumonia, or they can be unusual bacterial, fungal, or parasitic infections. Neonatal screening for severe combined immunodeficiency syndrome, one of the most common and serious PIDs, is now performed in most US states, but many PIDs manifest and are detected after birth...
