Antibiotics have long been of great benefit for people, both in the medical treatment of human disease and in animal food that improves the growth performance and feed utilization during animal production. Antibiotics as in-feed supplements affect all stages of pork production, including the gestation, nursing, growing, and finishing stages, although the effects show stage-dependent differences. However, the use of antibiotics in animal feed has become a worldwide concern. This review describes why sub-therapeutic levels of antibiotic additives in animal feed have become an integral part of animal feeding programs for more than 70 years, particularly in pork production...

The effectiveness of essential oils (EOs), fluconazole (FLU) and mupirocin (MUP) used alone or in combination against mono-species and mixed Candida albicans/Staphylococcus aureus biofilms was examined. An experimentally established dual-species biofilm model, verified by fluorescence microscopy and viable cell counting, was used. Selected commercial EOs were tested: geranium, citronella and clove oils, which have been chemically characterized and found to differ in the content of the main components (qualitative and quantitative)...

Spiramycin is a 16-membered macrolide antibiotic produced by Streptomyces ambofaciens and used in human medicine for the treatment of various respiratory tract and genital infections. Several impurities were detected in spiramycin-fermentation broth, especially impurities D and F, which decreased the separation-extraction yield and increased production cost. Dextrins, as the main carbon source, influence the accumulation of spiramycin and impurities. In this work, two types of dextrin from vendor Y and Z were compared to study their influences on spiramycin production...

Infectious diseases impose serious public health burdens and continue to be a global public health crisis. The treatment of infections caused by multidrug-resistant pathogens is challenging because only a few viable therapeutic options are clinically available. The emergence and risk of drug-resistant superbugs and the dearth of new classes of antibiotics have drawn increasing awareness that we may return to the pre-antibiotic era. To date, lipopeptides have been received considerable attention because of the following properties: They exhibit potent antimicrobial activities against a broad spectrum of pathogens, rapid bactericidal activity and have a different antimicrobial action compared with most of the conventional antibiotics used today and very slow development of drug resistance tendency...

BACKGROUND: Vascularized composite allotransplantation (VCA) is a rapidly expanding field of transplantation and provides a potential treatment for complex tissue defects. Peripheral blood mononuclear cells (PBMCs) shortly incubated with the antibiotic and chemotherapeutic agent mitomycin C (MMC) can suppress allogeneic T cell response and control allograft rejection in various organ transplantation models. MMC-incubated PBMCs (MICs) are currently being tested in a phase I clinical trial in kidney transplant patients...

Failure of the right ventricle (RV) is a serious disease with a poor prognosis and limited treatment options. Signaling by α1-adrenergic receptors (α1-ARs), in particular the α1A-subtype, mediate cardioprotective effects in multiple heart failure models. Recent studies show that chronic treatment with the α1A-subtype agonist A61603 improves function and survival in a model of LV failure. The goal of this study was to determine if chronic A61603 treatment is beneficial in a RV failure model. We used tracheal instillation of the fibrogenic antibiotic bleomycin in mice to induce pulmonary fibrosis, pulmonary hypertension, and RV failure within 2 wk...

Ballast water discharges are potential sources for the spread of invasive and pathogenic aquatic organisms. Ballast waters from six ships docked in the Port of Singapore were tested to determine if indictor organisms fell within proposed standards for ballast water discharge according to regulation D-2 of the Ballast Water Management Convention (BWMC) guidelines. Vibrio species were cultured on media supplemented with beta-lactam antibiotics to determine the presence of antibiotic resistant Vibrio species in the ballast waters of these vessels...

Endophthalmitis, an inflammation of the eye due to perioperative infection, may occur after cataract surgery. Intraocular lenses (IOLs) loaded with an antibiotic have been proposed as an alternative to the conventional postoperative endophthalmitis prophylaxis, since the antibiotic is delivered directly to the target site. In this work, an IOL-based antibiotic releasing system was prepared from a copolymer used in the production of IOLs and a fluoroquinolone used in endophthalmitis prophylaxis (moxifloxacin, MFX)...

REVIEW
Penelope A Bryant, Naomi T Katz
Inpatient management is necessary in many situations, but medical and allied-health treatments are increasingly being used on an outpatient basis to allow patients who would traditionally have been admitted to hospital to remain at home. Home-based clinical management has many potential benefits, including reduced hospital-acquired infections, cost savings, and patient and family satisfaction. Studies in adults provide evidence for the benefits of home-based versus hospital-based intravenous antibiotics, but few studies inform practice in home-based intravenous antibiotic therapy for children...

The extensive, diverse communities that constitute the microbiome are increasingly appreciated as important regulators of human health and disease through inflammatory, immune, and metabolic pathways. We sought to elucidate pathways by which microbiota contribute to inflammatory, autoimmune cardiac disease. We employed an animal model of experimental autoimmune myocarditis (EAM), which results in inflammatory and autoimmune pathophysiology and subsequent maladaptive cardiac remodeling and heart failure. Antibiotic dysbiosis protected mice from EAM and fibrotic cardiac dysfunction...

INTRODUCTION: In recent years, developments in virological tools have led to the easy detection of rhinoviruses and enteroviruses (E/RV). Their detection is very frequent in cases of airway involvement in children and their demonstrated causality. But the morbidity of E/RV in the neonatal period is unknown due to lack of epidemiological data. The objective of this study was to evaluate the incidence and clinical characteristics of these infections in hospitalized neonates. MATERIALS AND METHODS: We retrospectively analyzed the virology specimens of all neonates hospitalized at the Caen University Hospital between 2006 and 2011...

BACKGROUND: Long-term (tunneled cuffed) hemodialysis catheters are frequently used vascular access in renal failure patients. Catheter-related bloodstream infection (CRBSI) is a common complication of long-term hemodialysis catheters, with severe morbidities and high risk of mortality. Management of CRBSI by systemic antibiotics while keeping the catheter in place is not effective. Among the different modalities of CRBSI management are catheter removal (CR) and guidewire exchange (GE) of the catheter...

Mycobacterium leprae, the causal agent of leprosy is non-cultivable in vitro. Thus, the assessment of antibiotic activity against Mycobacterium leprae depends primarily upon the time-consuming mouse footpad system. The GyrA protein of Mycobacterium leprae is the target of the antimycobacterial drug, Ofloxacin. In recent times, the GyrA mutation (A91V) has been found to be resistant to Ofloxacin. This phenomenon has necessitated the development of new, long-acting antimycobacterial compounds. The underlying mechanism of drug resistance is not completely known...

In Staphylococcus aureus, adherence and secretory proteins play chief role in the formation of biofilms. This mode of growth exhibits resistance to a variety of antibiotics and spreads its infections. In the present study, secretary and adherence proteins, Protein-A, Fibronectin-binding protein-A (FnbA) and Rsp (a transcription regulator encoding proteolytic property) expression levels were evaluated at different stages of growth in S. aureus ATCC12600 a drug-sensitive strain and multidrug-resistant strains of S...
