The methanolic leaf extract of Newbouldia laevis was subjected to preliminary phytochemical screening and in-vitro antimicrobial tests. The extract revealed the presence of flavonoids, tannins, terpenes, steroidal and cardiac glycosides. The antimicrobial activity of the plant extract was assayed by the agar plate disc diffusion and nutrient broth dilution techniques. Test microorganisms were P...

Over the past two decades, nosocomial infections caused by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella spp. have become a major problem all around the world. This situation is of concern because there are limited antimicrobial options to treat patients infected with these pathogens, and also because this kind of resistance can spread to a wide variety of Gram-negative bacilli. ...

INTRODUCTION Risk factors for nosocomial carbapenem-resistant Klebsiella spp. (CRK) infections were analyzed in this study. METHODOLOGY The incidence, clinical characteristics, risk factors, antimicrobial susceptibility, and outcomes of CRK infections during a seven-year period (2004-2010) were retrospectively analyzed. RESULTS A total of 720 patients were included in the study. Carbapenem ...

Removal of heavy metals from wastewater needs advance chemical technology and is more expensive too. The cheaper alternative for this is the bioremediation using heavy metals resistant microorganisms. In this study, 10 heavy metal resistant bacteria were isolated from oxidation ditch of wastewater treatment plant of Bagmati Area Sewerage Project. These include chromium resistant Staphylococcus ...

INTRODUCTION We evaluated blood culture-proven sepsis episodes occurring in microclusters in very-low-birth-weight infants born in the German Neonatal Network (GNN) during 2009-2010. METHODS Thirty-seven centers participated in GNN; 23 centers enrolled ≥50 VLBW infants in the study period. Data quality was approved by on-site monitoring. Microclusters of sepsis were defined as occurrence of a...

Pyogenic liver abscess (PLA) is the most frequent, potentially life-threatening type of visceral abscess, with an increasing incidence worldwide [1,2]. The etiologies and microbiological spectrum show distinct regional differences around the world. Klebsiella pneumoniae is the most common causative pathogen of PLA in eastern Asian countries [3-5], whereas Streptococcus spp. predominates in Euro...

We investigated the incidence of cases of nosocomial pathogens and risk factors in an intensive treatment unit ward to determine if the number of cases is dependent on location of patients and the colonization/infection history of the ward. A clustering approach method was developed to investigate the patterns of spread of cases through time for five microorganisms [methicillin-resistant Staphy...

We investigated the clinical usefulness of the revised 2010 Clinical and Laboratory Standards Institute (CLSI) breakpoints for Escherichia coli and Klebsiella spp. Of 2,623 patients with bacteremia caused by E. coli or Klebsiella spp., 573 who had been treated appropriately with cephalosporin based on the CLSI 2009 guidelines were enrolled. There were no differences in the rates of treatment fa...

Ampicillin-sulbactam (A/S) and amoxicillin-clavulanic acid (AUG) are thought to be equally efficacious clinically against the Enterobacteriaceae family. In this study, the in vitro activities of the A/S and AUG were evaluated and compared against Escherichia coli and Klebsiella spp. Antimicrobial susceptibility tests were performed by standard agar dilution and disc diffusion techniques accordi...

Background: Neonatal sepsis is a major cause of mortality and morbidity, especially in developing countries. The goal of the present study was to determine the bacterial etiology and antibiotic sensitivity patterns of neonatal sepsis. Methods: This cross sectional study was conducted on 208 neonates admitted with clinically suspected sepsis over a period of 30 months. Sepsis was divided into ea...
