Brucella abortus is an intracellular bacterial pathogen and an etiological agent of the zoonotic disease known as brucellosis. Brucellosis can be challenging to treat with conventional antibiotic therapies and, in some cases, may develop into a debilitating and life-threatening chronic illness. We used multiple independent assays of in vitro metabolism and intracellular replication to screen a library of 480 known bioactive compounds for novel B. abortus anti-infectives. Eighteen non-cytotoxic compounds specifically inhibited B...

BACKGROUND: According to expert opinions, gentamicin should be administered as an adjunct to penicillin against severe group B streptococcal (GBS) infections. Whether the adjunct is important is of particular interest for elderly patients. Not only is the risk of aminoglycoside nephrotoxicity higher in elderly persons, but their immune defence to bacterial infections may also be impaired. METHOD: Time-kill assays with human blood products, such as serum, neutrophilic granulocytes (opsonophagocytic assays) and whole blood from healthy, elderly volunteers were performed to evaluate the effect of gentamicin in combination with penicillin...

Elizabethkingia meningoseptica, formerly Chryseobacterium meningosepticum usually causes neonatal meningitis and is a rare cause of nosocomial meningitis in adults. E. meningoseptica is resistant to most antibiotics, and the use of inactive drugs as empirical therapy may contribute to poor outcome in many patients. Vancomycin, alone or in combination with rifampicin, has been successful in the treatment of meningitis in infants1. We present a case of E. meningoseptica meningitis in an adult who was treated initially with intravenous vancomycin and oral rifampicin, but did not respond to the treatment...

Purpose: Bacterial pneumonia is a common lung infection caused by different types of bacteria. Azithromycin (AZI), an azalide antibiotic, is widely used to manage pneumococcal infections. Studies have shown that antibiotics in nanocarriers may lead to increased antibacterial activity and reduced toxicity. The aim of this work was to valuate in vitro antibacterial performance azithromycin-Eudragit RS100 nano-formulations against Streptococcus pneumoniae and Staphylococcus aureus. Methods: AZI-Eudragit RS100 nanoparticles were prepared via electrospinning technique and the in vitro antibacterial performance against S...

Increasing evidence(s) have indicated that epithelial to mesenchymal transition (EMT) at the advanced stage of liver cancer, not only has the ability to self-renew and progress cancer, but also enables greater resistance to conventional chemo- and radio-therapies. Here, we report that ascochlorin (ASC), an isoprenoid antibiotic could potentiate the cytotoxic effect of doxorubicin (DOX) on HCCLM3, SNU387, SNU49, and SK-Hep-1 hepatocellular carcinoma (HCC) cells, which had a predominantly mesenchymal signature with low expression of E-cadherin but high expression of N-cadherin...

Antibiotic adjuvant therapy represents an exciting opportunity to enhance the activity of clinical antibiotics by co-dosing with a secondary small molecule. Successful adjuvants decrease the concentration of antibiotics used to defeat bacteria, increase activity (in some cases introducing activity against organisms that are drug resistant), and reduce the frequency at which drug-resistant bacteria emerge. We report that 5-alkyloxytryptamines are a new class of broad-spectrum antibacterial agents with exciting activity as antibiotic adjuvants...

The study was undertaken to describe the profile of patients and the characteristics of all multidrug-resistant gram-negative bacteria (MDR-GNB) and to assess mortality. We examined 138 patients with bloodstream infections (BSIs) caused by MDR-GNB. Clinical characteristics, antibiotic therapy, and in-hospital mortality were analyzed. Survivor and nonsurvivor subgroups were compared to identify predictors of mortality. The in-hospital mortality rate was 25.4%. Univariate analysis revealed that comorbidities and inadequate initial antimicrobial treatment could increase risk of death...

We report a case of a 77-year old male who developed a fulminant erysipelas and sepsis, caused by Myroides odoratimimus. Selecting the optimal antibiotic therapy for the treatment of infections with M. odoratimimus is challenging due to limited clinical experience with this micro-organism and its reported multidrug-resistance. Review of previous studies concerning in vitro antibacterial susceptibility and clinical experience with M. odoratimimus resulted in six case reports describing bacteremia, soft tissue and bone infections, pneumonia and urinary tract infections...

Worrying levels of bacterial resistance have been reported worldwide involving the failure of many available antibiotic treatments. Multidrug resistance (MDR) in Gram-negative bacteria is often ascribed to the presence of multiple and different resistance mechanisms in the same strain. RND efflux pumps play a major role and are an attractive target to discover new antibacterial drugs. Areas covered: This review discusses the prevalence of efflux pumps, their overexpression in clinical scenarios, their polyselectivity, their effect on the intracellular concentrations of various antibiotics associated with the alteration of the membrane permeability and their involvement in pathogenicity are discussed...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a significant cause of morbidity and mortality, complicating the medical course of approximately 10% of mechanically-ventilated patients, with an estimated attributable mortality of 13%. To treat VAP empirically, the American Thoracic Society currently recommends antibiotic therapy based on the patients' risk of colonisation by an organism with multidrug resistance. The selection of initial antibiotic therapy in VAP is important, as inappropriate initial antimicrobial treatment is associated with higher mortality and longer hospital stay in intensive care unit (ICU) patients...

Selective immunoglobulin A deficiency (SIgAD) is the most common primary antibody deficiency. Although more patients with SIgAD are asymptomatic, selected patients suffer from different clinical complications such as pulmonary infections, allergies, autoimmune diseases, gastrointestinal disorders and malignancy. Pathogenesis of SIgAD is still unknown, however, a defective terminal differentiation of B-cells and defect in switching to IgA-producing plasma cells are presumed to be responsible. Furthermore, some cytogenic defects and monogenic mutations are associated with SIgAD...
