Use of antibiotics as feed additives in poultry production has been linked to the presence of antibiotic resistant bacteria in farm workers, consumer poultry products and the environs of confined poultry operations. There are concerns that these resistant bacteria may be transferred to communities near these operations; however, environmental pathways of exposure are not well documented. We ass...

discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...

BACKGROUND & OBJECTIVES Since the incidence of vancomycin- and methicillin-resistant Gram-positive infections continue to increase, novel antimicrobials such as linezolid and streptogramin may provide new options to treat patients. The aim of this study was to investigate in vitro susceptibility of Enterococcus faecium resistant to glycopeptides, coagulase negative staphylococci and S. aureus r...

  Background and Objective: Reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (CoNS). The objective of the present study was to compare and evaluate the performance of disc diffusion and E test (Epsilometer test) methods for antimicrobial testing of coagulase ne...

Gram-positive pathogens are a major cause of healthcare-associated and community-acquired bacterial infections. Staphylococci (mostly Staphylococcus aureus but also coagulase-negative staphylococci), enterococci, streptococci, and Clostridium difficile are the most important species of clinical interest. Antibiotic resistance issues are common among Gram-positive pathogens, especially among sta...

(2011): Occurrence and characteristics of methicillin resistant Staphylococcus aureus and methicillin resistant coagulase-negative staphylococci in raw milk manufacturing. Czech J. Food Sci., 29 (Special Issue): S11–S16. For monitoring the occurrence of MRSA (methicillin resistant Staphylococcus aureus) and MR-CNS (methicillin resistant coagulase-negative stap...

BACKGROUND Methicillin resistance is a serious health concern since it has spread among Staphylococcus aureus and coagulase-negative Staphylococci (CoNS) that are frequent community and nosocomial pathogens worldwide. Methicillin-resistant strains are often resistant to other classes of antibiotics, making their treatment difficult. Nigella sativa oil is known to be active against Gram-positive...

Staphylococci and streptococci are leading causes of healthcare community-acquired bacterial infections worldwide. Within each genus, virulent species such as Staphylococcus aureus, Streptococcus pyogenes pneumoniae associated with diverse syndromes superficial infection, invasive infection exotoxin production. less coagulase-negative staphylococci viridans common harmless human commensals but ...

Sir, To follow-up our previous finding of reduced polystyrene adherence accompanying the acquisition of linezolid resistance in a clinical bloodstream isolate of methicillin-resistant Staphylococcus aureus (MRSA), we evaluated the polystyrene adherence properties of linezolid-resistant staphylococci obtained from our institution as well as isolates obtained from multiple medical centres through...

The relative frequency of 10 determinants of resistance to macrolides, lincosamides, and streptogramins was investigated by PCR in a series of 294 macrolide-, lincosamide-, and/or streptogramin-resistant clinical isolates of Staphylococcus aureus and coagulase-negative staphylococci isolated in 1995 from 32 French hospitals. Resistance was mainly due to the presence of ermA or ermC genes, which...
