BACKGROUND The emergence of multidrug resistant Staphylococcus aureus strains, including methicillin resistant (MRSA), is a global concern. Treatment of bacterial infections in Uganda's health care settings is largely empirical, rarely accompanied by laboratory confirmation. Here we show the burden, characteristics of MRSA and epidemiology of Panton-Valentine Leukocidin (PVL) positive strains i...

AIMS To compare conventional phenotypic methods for the detection of methicillin and mupirocin resistance in Staphylococcus aureus in routine laboratory practice with reference to an established molecular method. METHODS This study was conducted on a selection of 65 isolates of methicillin resistant Staphylococcus aureus (MRSA) from a burns unit in India which is endemic for MRSA. The Kirby-B...

BACKGROUND Staphylococcus aureus is a harmful pathogen known to express numerous virulence factors and cause severe infections. High levels of methicillin-resistant Staphylococcus aureus (MRSA) strains are one of the important healthcare problems because of the inefficient treatment of these infections. OBJECTIVES The purpose of the current study is to evaluate the incidence of the toxic shoc...

We investigated the effects of adenosine on prolactin (PRL) secretion from rat anterior pituitaries incubated in vitro. The administration of 5-N-methylcarboxamidoadenosine (MECA), an analog agonist that preferentially activates A2 receptors, induced a dose-dependent (1 nM to 1 microM) increase in the levels of PRL released, an effect abolished by 1,3-dipropyl-7-methylxanthine, an antagonist of...

INTRODUCTION Staphylococcus aureus is the etiological agent for a wide range of human infections, and its pathogenicity largely depends on various virulence factors associated with adherence, evasion of the immune system and damage of the host. This study determined the prevalence of methicillin-resistant S. aureus (MRSA) and some selected virulence genes in clinical isolates of S. aureus from ...

This study was undertaken to identify the adenosine receptor (AR) subtypes which down-regulate the proinflammatory activities of human neutrophils, as well as the involvement of adenosine 3',5'-cyclic monophosphate (cAMP) and its relationship to cellular handling of Ca(2+) in mediating these effects. Neutrophils were treated with varying concentrations (0.01-1 microM) of AR agonists operative a...

Activation of the Gi-protein-coupled A3 adenosine receptor (A3AR) has been reported to be involved in the inhibition of tumor cell growth. A3AR is highly expressed in tumor cells whereas lower expression was noted in a variety of normal cells. Recently we showed that A3AR activation in melanoma cells resulted in growth inhibition via a direct anti-proliferative effect which entailed cell cycle ...

BACKGROUND We aimed to investigate the prevalence of disinfectant resistance genes (qacA/qacB,qacC) and the aminoglycosides resistance genes [(aac(6')aph(2''),aph(3')-IIIa,ant(4')-Ia)] in both S. aureus and coagulase-negative staphylococcal strains (CoNS) isolated from surgical site infections. MATERIAL AND METHODS Totally, 130 staphylococcal strains isolated from surgical site infections bet...
