BACKGROUND Control of brucellosis in livestock, wildlife and humans depends on the reliability of the methods used for detection and identification of bacteria. In the present study, we describe the evaluation of the recently established real-time PCR assay based on the Brucella-specific insertion sequence IS711 with blood samples from 199 wild boars (first group of animals) and tissue samples ...

Objective: To compare serological and molecular assays for detection hepatitis B virus infection. Methods: A total of two hundreds patient were included with age range between 20 years and 60 years. Samples were obtained to detect serological markers of HBV infection using Enzyme linked immunosorbent assay (ELISA) and for HBV DNA quantitation through performing real time polymerase chain reacti...

BACKGROUND AND OBJECTIVES Human Papillomavirus (HPV) infection is a major risk factor for adenocarcinoma of the cervix. The high-risk types of the virus such as HPV16 and HPV18, which possess the E6 and E7 oncogenes, are responsible for approximately 50% of all cervical cancers. A rapid, sensitive and specific test has been proposed for detection of HPV to improve cervical cancer screening prog...

In order to overcome some of the limitations of conventional microbiological techniques in the diagnosis of human brucellosis, a simple PCR-enzyme-linked immunosorbent assay (PCR-ELISA) was developed. After amplification of a 223-bp sequence of a gene that codes for the synthesis of an immunogenetic membrane protein specific for the Brucella genus (BCSP31), the digoxigenin-labeled amplified pro...

Accurate and timely detection is vital for mitigation of tuber yield losses resulting from yam mosaic virus (YMV) infection on yam, a major food security crop in West Africa. The observation, from our previous studies, that the triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA), the most commonly used detection method for YMV, detected the virus in significantly less leaf sa...

Contamination of retail poultry by Campylobacter spp. and Salmonella enterica is a significant source of human diarrheal disease. Isolation and identification of these microorganisms require a series of biochemical and serological tests. In this study, Campylobacter ceuE and Salmonella invA genes were used to design probes in PCR-enzyme-linked immunosorbent assay (ELISA), as an alternative to c...

We compared the usefulness of a polymerase chain reaction (PCR) assay for the early diagnosis of invasive pulmonary aspergillosis with the serodiagnosis of sufficient concentrations of galactomannan using the same serum samples. A patient was treated with prednisolone for the management of hepatitis. Computed tomography (CT) scan of the chest showed the nodular shadow with a cavity containing a...

A microneutralization assay using an ELISA-based endpoint assessment (ELISA-MN) is widely used to measure the serological response to influenza virus infection and vaccination. We have developed an alternative microneutralization assay for influenza virus using a quantitative reverse transcription PCR-based endpoint assessment (qPCR-MN) in order to improve upon technical limitations associated ...

Thesis Abstract Several cytokines are known to be involved in the pathogenesis of non-Hodgkin Lymphomas (NHL). Given importance understanding genetic predisposition NHL, this work was designed study impact IL-10 (-1082 G/A; rs1800896 and -819 C/T; rs1800871), IL-6 (-174 G/C; rs1800795) CD38 (184C/G; rs6449182) gene polymorphisms on susceptibility Egyptians NHL. Both loci IL10 were genotyped usi...

and Implications The ELISA assay is a more rapid and sensitive method for PCR product detection than conventional gel electrophoresis. The PCR/ELISA allows for the processing of numerous samples, is relatively inexpensive and eliminates the need for electrophoretic and photographic equipment as well as the use of potential carcinogens such as ethidium bromide which is utilized in the gel electr...
