BACKGROUND AND OBJECTIVES: The number of patients with multiresistant bacteria (MRB) in rehabilitation facilities is increasing. The increasing costs of hygienic isolation measures reduce resources available for core rehabilitation services. In addition to the existing lack of care, patients with MRB are at further risk of being given lower priority for admission to rehabilitation facilities. Therefore, the Hygiene Commission of the German Society for Neurorehabilitation (DGNR) attempted to quantify the overall risk for deterioration of rehabilitation care due to the financial burden of MRB...

BACKGROUND: Escherichia coli O157 is an important food-borne pathogen that can cause diarrhoea, hemorrhagic colitis, and hemolytic uraemic syndrome. Enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) and multilocus sequence typing (MLST) are good methods for molecular typing and the extensive use of antibiotics is a contributing factor to the increasing incidence of antimicrobial-resistant for these strains. OBJECTIVES: The aim of this study was to determine the prevalence, antimicrobial resistance, and genetic diversity of E...

The folate receptor (FR) is expressed in a variety of gynecological cancer types. It has been widely used for tumor targeting with folic acid conjugates of diagnostic and therapeutic probes. The cervical KB tumor cells have evolved as the standard model for preclinical investigations of folate-based (radio) conjugates. In this study, a panel of FR-expressing human cancer cell lines-including cervical (HeLa, KB, KB-V1), ovarian (IGROV-1, SKOV-3, SKOV-3.ip), choriocarcinoma (JAR, BeWo) and endometrial (EFE-184) tumor cells-was investigated in vitro and for their ability to grow as xenografts in mice...

The wide abuse of antibiotics has accelerated bacterial multiresistance, which means there is a need to develop tools for rapid detection and characterization of bacterial response to antibiotics in the management of infections. In the study, an electrochemical biosensor based on nanoporous alumina membrane and graphene quantum dots (GQDs) was developed for bacterial response to antibiotics detection. Anti-Salmonella antibody was conjugated with amino-modified GQDs by glutaraldehyde and immobilized on silanized nanoporous alumina membranes for Salmonella bacteria capture...

Opportunistic infections constitute a major challenge for modern medicine mainly because the involved bacteria are usually multiresistant to antibiotics. Most of these bacteria possess remarkable ability to adapt to various ecosystems, including those exposed to anthropogenic activities. This study isolated and identified 21 multiresistant opportunistic bacteria from two polluted rivers, located in Algiers. Cadmium, lead, and copper concentrations were determined for both water samples to evaluate heavy metal pollution...

RATIONALE: Intracranial infection with Acinetobacter baumannii is a tough problem due to the presence of multiresistance and drugs poor penetration through the blood brain barrier (BBB). Tigecycline is effective to cure A baumannii, but it can only be used intravenously which is also difficult to pass BBB. So, it will be a breakthrough if intraventricular (IVT) tigecycline is used in the clinical therapy. However, this treatment has been reported quite rarely until now. PATIENT CONCERNS: We described a case of a 50-year-old male worker whose clinical futures were high fever and cerebral rigidity after neurosurgery...

This study provides an estimate of antimicrobial resistance in intestinal indicator bacteria from humans (n = 97) and food animals (n = 388) in Tanzania. More than 70% of all fecal samples contained tetracycline (TE), sulfamethoxazole (STX), and ampicillin (AMP)-resistant coliforms, while cefotaxime (CTX)-resistant coliforms were observed in 40% of all samples. The average Log10 colony forming units/g of CTX-resistant coliforms in samples from humans were 2.20. Of 390 Escherichia coli tested, 66.4% were resistant to TE, 54...

The infectious diseases caused by multidrug-resistant bacteria pose serious threats to humankind. It has been suggested that an antibiotic targeting LpxC of the lipid A biosynthetic pathway in Gram-negative bacteria is a promising strategy for curing Gram-negative bacterial infections. However, experimental proof of this concept is lacking. Here, we describe our discovery and characterization of a biphenylacetylene-based inhibitor of LpxC, an essential enzyme in the biosynthesis of the lipid A component of the outer membrane of Gram-negative bacteria...

Antimicrobial resistance is one of the greatest threats to human health worldwide. The rate of development of newer antibiotics is much slower than the rate of development of antibiotic resistance. A survey reported that it takes 15 years and US$800 million (including preclinical and clinical costs) to bring a single drug to the market, whereas the reuse of the older drugs for antimicrobial use takes $17 million, thereby circumventing 40% of the overall cost. The first case is a patient with nosocomial pyrexia of unknown origin who was given treatment with tigecycline and cefepime/tazobactam but failed to respond to the same...

The increase in the number of bacterial strains resistant to known antibiotics is alarming. In this study we report the synthesis of novel compounds termed Lipophosphonoxins II (LPPO II). We show that LPPO II display excellent activities against Gram-positive and -negative bacteria, including pathogens and multiresistant strains. We describe their mechanism of action-plasmatic membrane pore-forming activity selective for bacteria. Importantly, LPPO II neither damage nor cross the eukaryotic plasmatic membrane at their bactericidal concentrations...
