Empiric initial antibiotic therapy of bacterial infections is based primarily upon the susceptibility of the most common causative pathogens. The purpose of this study was to provide susceptibility data on six bacterial species known to cause ear, nose and throat (ENT) infections. A total of 1066 isolates collected during a nationwide laboratory-based surveillance study were analysed. All Streptococcus pyogenes isolates were penicillin (PEN)-susceptible, indicating that natural penicillins can still be recommended as the first-line treatment for group A streptococcal tonsillopharyngitis...

The molecular pathways that regulate the tissue repair function of type I interferon (IFN-I) during acute tissue damage are poorly understood. We describe a protective role for IFN-I and the RIG-I/MAVS signaling pathway during acute tissue damage in mice. Mice lacking mitochondrial antiviral-signaling protein (MAVS) were more sensitive to total body irradiation- and chemotherapy-induced intestinal barrier damage. These mice developed worse graft-versus-host disease (GVHD) in a preclinical model of allogeneic hematopoietic stem cell transplantation (allo-HSCT) than did wild-type mice...

We report two cases of bacteremia due to Clostridium difficile from two French hospitals. The first patient with previously diagnosed rectal carcinoma underwent courses of chemotherapy, and antimicrobial treatment, and survived the C. difficile bacteremia. The second patient with colon perforation and newly diagnosed lung cancer underwent antimicrobial treatment in an ICU but died shortly after the episode of C. difficile bacteremia. A review of the literature allowed the identification of 137 cases of bacteremia between July 1962 and November 2016...

Pelvic lymphoceles are an infrequent complication after pelvic surgery and develop shortly after the surgery in most cases. We experienced a case of delayed infection of a lymphocele 6 months after robot-assisted radical prostatectomy (RARP) and pelvic lymphadenectomy. In this case, antimicrobial chemotherapy and percutaneous drainage were effective, and there was no recurrence of the disease. Most urologists do not recognize that infected lymphoceles can develop a long time after surgery; thus, infected lymphoceles should be kept in mind in patients with nonspecific infectious symptoms, regardless of the length of time after surgery...

The number of reported cases of infections due to Capnocytophaga species (spp.) is limited. We herein describe four cases developing bacteremia due to Capnocytophaga spp. during neutropenia after chemotherapy for hematological malignancies. At the onset of bacteremia, 3 of the 4 patients had oral mucositis, and 2 were co-infected with other bacteria. Two patients developed bacteremia while receiving fluoroquinolone as prophylaxis against bacterial infection. Bacteremia resolved with administration of antimicrobial agents in all patients and no recurrences were observed thereafter...

INTRODUCTION: Helicobacter fennelliae is an enterohepatic Helicobacter species causing bacteraemia in immunocompromised hosts. Only a few cases of recurrent H. fennelliae bacteraemia have been reported in Japan and there are no guidelines regarding antimicrobial treatment for H. fennelliae infection. CASE PRESENTATION: H. fennelliae bacteraemia was observed in a patient receiving platinum-based chemotherapy for lung cancer. To prevent recurrence, the patient received antibiotic therapy with cefepime, amoxicillin and doxycycline for 6 weeks, which is similar to the therapy for Helicobactercinaedi bacteraemia...

Global tuberculosis incidence has declined marginally over the past decade, and tuberculosis remains out of control in several parts of the world including Africa and Asia. Although tuberculosis control has been effective in some regions of the world, these gains are threatened by the increasing burden of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis. XDR tuberculosis has evolved in several tuberculosis-endemic countries to drug-incurable or programmatically incurable tuberculosis (totally drug-resistant tuberculosis)...

Quorum sensing (QS) plays an important role in virulence of Pseudomonas aeruginosa, blocking of QS ability are viewed as viable antimicrobial chemotherapy and which may prove to be a safe anti-virulent drug. Bioactive components from Piper betle have been reported to possess antimicrobial ability. This study envisages on the anti-QS properties of ethanolic extract of P. betle leaf (PbLE) using P. aeruginosa PAO1 as a model organism. A marked reduction in swarming, swimming, and twitching ability of the bacteria is demonstrated in presence of PbLE...

Patients with acute leukemia are susceptible to chemotherapy-induced severe myelosuppression, and therefore are at a high risk for febrile neutropenia (FN). In such cases, the use of broad-spectrum antibiotics such as fourth-generation cephalosporins and carbapenems is recommended as first-line antimicrobial treatment; however, the effectiveness of these agents in patients with acute myeloid leukemia (AML) has not been investigated in detail. We retrospectively examined and evaluated the effectiveness of first-line antibiotic treatment regimens for chemotherapy-induced FN in patients with AML in Japanese Red Cross Nagoya Daiichi Hospital...

Tuberculosis is a global health problem that causes the death of approximately 1.5 million people worldwide each year (WHO, p. 1-126, Global Tuberculosis Report, 2015). Treatment of drug-susceptible tuberculosis requires combination antimicrobial therapy with a minimum of four antimicrobial agents applied over the course of 6 months. The first instance of combination antimicrobial therapy applied to tuberculosis was the joint use of streptomycin and para-aminosalicylic acid as documented by the Medical Research Council of the United Kingdom in 1950...

REVIEW
Mohsen Chitsaz, Melissa H Brown
Antimicrobial resistance is a current major challenge in chemotherapy and infection control. The ability of bacterial and eukaryotic cells to recognize and pump toxic compounds from within the cell to the environment before they reach their targets is one of the important mechanisms contributing to this phenomenon. Drug efflux pumps are membrane transport proteins that require energy to export substrates and can be selective for a specific drug or poly-specific that can export multiple structurally diverse drug compounds...

Photodynamic antimicrobial chemotherapy (PACT) uses non-traditional mechanisms (free radicals) and is a highly advocated method with promise of inactivating drug-resistance bacteria for local infections. However, there is no related drug used in clinical practice yet. Therefore, new photosensitizers for PACT are under active development. Here, we report the synthesis of a series of photosensitizers with variable positive charges (ZnPc(TAP)4(n+), n = 0, 4, 8, 12) and their inactivation against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria...

BACKGROUND: Mucositis is one of the most relevant gastrointestinal inflammatory conditions in humans, generated by the use of chemotherapy drugs, such as 5-fluoracil (5-FU). 5-FU-induced mucositis affects 80% of patients undergoing oncological treatment causing mucosal gut dysfunctions and great discomfort. As current therapy drugs presents limitations in alleviating mucositis symptoms, alternative strategies are being pursued. Recent studies have shown that the antimicrobial pancreatitis-associated protein (PAP) has a protective role in intestinal inflammatory processes...

Essential facts Many patients admitted to hospital or receiving care in other settings, including their own homes, are recipients of one or more infusion therapies. Total parenteral nutrition, chemotherapy, parenteral antimicrobial therapy, pain relief and other infusion therapies are increasingly delivered in community settings. While the move away from hospital helps meet patients' lifestyles and clinical needs, it can have implications for patient care and safety.
