Introduction: Enteric fever continues to be a global health problem and isolation of organism from blood is the gold standard for the diagnosis. Objectives: Aim of this study was to find out the usefulness of three different methods such as blood culture, clot culture & Widal test for diagnosis of enteric fever. Materials & Methods: Total number of blood samples collected was 290 from patients ...

INTRODUCTION Although typhoid fever is confirmed by culture of Salmonella Typhi, Widal test is widely used in India but little information exists about its reliability. MATERIALS AND METHODS We examined the performance of Widal test in our hospital for diagnosis of typhoid fever in children. Hundred consecutive pediatric in-patients for whom, the Widal test was requested were grouped into fou...

AIMS To compare the established Widal agglutination assay with an immunoblotting procedure. METHODS 110 sera were used to compare the established Widal agglutination assay with an immunoblotting procedure incorporating lipopolysaccharide (LPS) (O = 9,12) and flagellar (H = d) antigens. RESULTS Antibodies to the LPS antigens were detected in 18 sera by the Widal assay and in 37 by immunoblot...

BACKGROUND The Widal test is the most common, specific and quick diagnostic method available in the world for diagnosis of typhoid fever; however, false negativity is one of the obstructive features of the test. The aim of this study was to evaluate the associated factors with Widal test negativity in an endemic area. METHODS Widal test negativity was retrospectively analyzed among culture-pr...

BACKGROUND AND PURPOSE Widal test is frequently applied for the detection of Salmonella agglutinins to diagnose Salmonella enterica serotype Typhi infection. There are however a number of controversies challenging the diagnostic utility of this test. This study was performed to determine the prevalence of Salmonella agglutinins in patients with other febrile illnesses and healthy blood donors. ...

Isolation of the causative organism from the blood and other body fluids remains the definitive test for the diagnosis of typhoid fever. But this isolation requires ...

Introduction: Typhoid fever the common cause of morbidity and mortality especially in the developing countries where Widal test is routinely used as diagnostic tool to rule out the disease. The diagnostic ability of Widal test is debatable as the test method has a low sensitivity, specificity and positive predictive value (PPV). Therefore, reviewing articles across the world regarding the diagn...

come across cases which are clinically true cases of typhoid fever, but in which curiously enough the Widal reaction remains completely negative during the whole course of the disease, and some of these cases recover. My object in writing this note is to discuss these aberrant negative results in the Widal reaction. In some patients the Widal reaction has been observed to be positive in as high...

BACKGROUND Widal test, which has poor predictive outcomes in predominant typhoid population, is not standard enough to predict accurate diagnosis. This study aims to compare the diagnostic accuracy of Widal test to ELISA using blood culture as gold standard. METHODS The blood samples were collected in Capital Hospital, Kathmandu, Nepal from febrile patients having ≥48 h fever in 3 years study...
