background: to study toxoplasmosis in neonates using pcr and serological methods. methods: sera and csf of 104 neonates, hospitalized in infants' ward of taleghani hospital, tehran, iran were examined. the sera were examined for anti toxoplasma gondii lgm and lgg specific antibodies with elisa and ifa techniques, respectively. meanwhile, obtained csfs of the cases were evaluated for the genome ...
Pesticides are used globally for enhancing crop yields. However, their excessive use/misuse, especially in the developing countries, results in widespread food and environmental contamination. Therefore current methods such as gas chromatography and high-performance liquid chromatography have been used successfully, with great sensitivity and reliability, for analysis of many pesticides. Howeve...
Background and purpose: Enteropathogenic Escherichia coli from Enterobacteriaceae family is one of the most common causes of chronic diarrhea in children and infants. Polymerase Chain Reaction (PCR) method is commonly used for detection of enteropathogenic Escherichia coli species, but there are some disadvantages with this method due to the use of gel electrophoresis and staining with ethidium...
Objective: Klebsiella Pneumoniae is one of the most important infection bacteria of the Enterobacteriaceae family. It is also the second factor of hospital bacteremia due to the gram negative bacteria after Escherichia coli. In this research, this bacteria with the private 16SrDNA gene, was identified through PCR-ELISA technique. Materials and Methods: In this method the dNTP labeled with Digox...
The results of examination of 375 bovine serum and 150 bovine milk samples for detection of bovine leukemia virus infection by the immunodiffusion technique were compared with those of an enzyme-linked immunosorbent assay (ELISA). It was concluded that the ELISA is another useful method for the detection of antibodies to bovine leukemia virus in serum and milk. The ELISA provides a quantitative...
Three commercially available diagnostic assays for the detection of antibodies to varicella-zoster virus were evaluated to determine which would be the most suitable for our clinical laboratory. Three different methods were examined: an enzyme-linked immunosorbent assay (ELISA), latex agglutination (LA), and an indirect fluorescent-antibody technique. For the 141 serum specimens tested, the ELI...
