Extended spectrum ?-lactamase (ESBLs), produced by Gram negative organisms, are enzymes capable of hydrolyzing extended spectrum cephalosporins, penicillins and monobactam but inactive against cephamycin and imipenem. Detection of some ESBL strains are missed by Double disc synergy test but detected by three dimensional test. So this study was carried out to see the rate of ESBL producer by three dimensional test and double disc synergy test among Gram negative bacteria. Total 110 Gram negative isolates were studied, among them 30 were wound swab isolates and 80 were laboratory isolates, of which 88(80%) were ESBL producer. Three dimensional tests detected ESBL in 88 (80%) strain whereas 66.36% strains detected by double disc synergy test, so 15 (13.63%) isolates were missed by Double disc synergy test. In this study among the 30 wound swab isolates Three dimensional test detected 26 (86.67%) whereas 14 (46.67) were detected by double disc synergy test and similarly among the 80 laboratory isolates, three dimensional test detected 62 (77.5%) and double disc synergy test detected 59 (73.75%). So, the three dimensional test has been found to be better than Double disc synergy test in the detection of ESBLs. ESBL producing organisms are resistance to most of the antibiotics but 100% sensitive to Imipenem. DOI: http://dx.doi.org/10.3329/pulse.v6i1-2.20328 Pulse Vol.6 January-December 2013 p.12-19

BACKGROUND AND OBJECTIVE: Serum magnesium, an essential trace element involved in processes that regulate cardiovascular function, has been linked to the risk of atherosclerotic cardiovascular disease. However, the…
Background: New devices have recently been developed using various features of the waveform derived from a brachial cuff for noninvasive estimation of central systolic blood pressure (SBP). Central SBP estimated from…
Background: Genetic variants causing diseases with hypertension as a secondary feature have previously been identified. Studies focussing on primary hypertension have utilised common and latterly rare genetic variants…
Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease. Recently, noninvasive and simple morphological and functional methods have been introduced to assess atherosclerotic vascular…
Background: Previous analyses have identified common variants along with some specific genes and rare variants which are associated with risk of hypertension, but much remains to be discovered. Methods and Results…
The noticeable characteristics of the blood vascular structure are the inconsistent viscosity of blood and the stiffness of the vascular wall. If we can control these two factors, we can solve more problems related to…
INTRODUCTION: Familial Mediterranean fever (FMF) is an autoinflammatory fever syndrome distinguished by recurrent attacks of spontaneous peritonitis, pleuritis, fever, and arthritis. It is specifically seen in the…
Accumulating evidence indicates that central blood pressure (CBP) is a better cardiovascular risk predictor than brachial blood pressure (BP). Although more additional benefits of CBP-based treatment above usual…
Introduction: Nonalcoholic fatty liver disease (NAFLD) is associated with vascular dysfunction, one of the signs of which is arterial stiffness. Carotid-femoral pulse wave velocity (PWV), which is considered the gold…
The use of left ventricular assist devices (LVADs), whether for destination therapy or bridge to transplantation, has gained increasing validation in recent years in patients with advanced heart failure. Arrhythmias can…
