BACKGROUND Staphylococcus aureus is one of the most important contagious bacteria causing subclinical bovine mastitis. This bacterial infection is commonly identified by determine the pathogen in bovine milk samples through conventional technique including coagulase test. However, this test has several disadvantages as low sensitivity, risk of biohazard, cost expensive, and limited preparation ...
Introduction: Nosocomial infections are responsible for the much of the morbidity and mortality found in hospitals. The present study was conducted on 70 bacterial strains isolated from hospitalized patients in various medical units of Baqiyatallah Hospital in Tehran, Iran during a period of 12 months from; March to February 2009. Methods: The bacterial s...
A fully automated method for detecting significant bacteriuria is described which uses firefly luciferin and luciferase to detect bacterial ATP in urine. The automated method was calibrated and evaluated, using 308 urine specimens, against two reference culture methods. We obtained a specificity of 0.79 and sensitivity of 0.75 using a quantitative pour plate reference test and a specificity of ...
68 نمونه سالمونلا - تیغی موریوم (salmonella typhimurium) که از بیماران بخش اطفال بیمارستان سعدی جدا شده بود و برای تولید کلیسین (colicin) مورد آزمایش قرار گرفت . از این تعداد 11 نمونه قابلیت تولید این پروتئین را نشان دادند. این نمونه ها همگی در تست حساسیت به آنتی بیوتیکهای مختلف (antibiotic sensitivity test) و همینطور phage typing تقریبا" یک نوع عمل کرد داشتند و همگی در سروتیپ (serotype) سالمون...
introduction: the suspected water samples contaminated with legionella were enriched with acanthamoebae. small numbers of bacteria (not detectable by culture) can be multiplied in amoebae up to culturable level in co-culture condition. the conventional culture method for legionnaires' disease bacterium always suffers from low sensitivity. this co-culture method can significantly improve culture...
BACKGROUND Peptide nucleic acid (PNA) probes are artificial DNA analogues with a hydrophobic nature that can penetrate the mycobacterial cell wall. We evaluated a FISH method for simultaneous detection and identification of Mycobacterium tuberculosis (MTB) and non-tuberculous mycobacteria (NTM) in clinical respiratory specimens using differentially labeled PNA probes. METHODS PNA probes targe...
BACKGROUND Poor targeting of antimicrobial drugs contributes to the millions of deaths each year from malaria, pneumonia, and other tropical infectious diseases. While malaria rapid diagnostic tests have improved use of antimalarial drugs, there are no similar tests to guide the use of antibiotics in undifferentiated fevers. In this study we estimate the diagnostic accuracy of two well establis...
A PCR-based assay that can simultaneously detect and differentiate five different types of nosocomial bacterial pathogens was developed. Six pairs of selected primers targeting femA (132 bp) and mecA (310 bp) of methicillin-resistant Staphylococcus aureus, gltA (722 bp) of Acinetobacter baumannii, phoA (903 bp) of Escherichia coli, mdh (364 bp) of Klebsiella pneumoniae and oprL (504 bp) of Pseu...
Urinary tract infection is the most common of all pediatric bacterial infections. This study aims to determine efficacy rapid diagnostic tests vs gram stain as against gold standard test (urine culture) and find out validity each screening for early detection urinary in children. A cross-sectional was conducted on children aged between 3- 15 years suspected infections from August 2020 January 2...
BACKGROUND The gold standard for diagnosis of typhoid fever is blood culture (BC). Because blood culture is often not available in impoverished settings it would be helpful to have alternative diagnostic approaches. We therefore investigated the usefulness of clinical signs, WHO case definition and Widal test for the diagnosis of typhoid fever. METHODOLOGY/PRINCIPAL FINDINGS Participants with...
