Comparison of a new commercially prepared porphyrin test and the conventional satellite test for the identification of Haemophilus species that require the X factor.

چکیده
A test with a commercially developed porphyrin test agar was examined for the identification of Haemophilus spp. The porphyrin test agar method was compared with the conventional paper strip satellite method in tests with 187 isolates and was found to be easier to perform and interpret, giving a sensitivity of 98.7% and specificity of 94.7%.

Rapid speciation of Haemophilus with the porphyrin production test versus the satellite test for X.
The detection of porphyrins produced from omega-aminolevulinic acid was evaluated for use in speciation of the Haemophilus. Two hundred and forty-eight clinical isolates of nonhemolytic Haemophilus were tested concurrently for porphyrin production and for X and V requirements. The porphyrin production test was more rapid (4 h) and more accurate than the satellite test.
متن کاملThe comparison of PCR technique and API-20E kit with the conventional biomedical methods for the identification of Salmonella species in laboratory
Abstract Bachground and objectives: Salmonella is one of the most important agents of gastrointestinal infection and diarrhea in our country. Misdiagnosis of these bacteria leads to cure failure. The aim of this study was to make a comparison between PCR and the API-20E and conventional biochemical tests carried out for the identification of Salmonella. Material and Methods: In this study 470 s...
متن کاملExpression of Recombinant Coagulation Factor IX in Human Amniotic Membrane-derived Mesenchymal Stem Cells: A New Strategy to Gene Therapy of Hemophilia B
Background: Hemophilia B is an X-linked hereditary disorder of blood coagulation system which is caused by factor IX (FIX) deficiency. Factor IX is a plasma glycoprotein that participates in the coagulation process leading to the generation of fibrin. Replacement of factor IX with plasma-derived or recombinant factor IX is the conventional treatment for hemophilia B to raise the factor IX le...
متن کاملComparison of bacterial biomass and PRP production between different isolation of Haemophilus influenza type-b (Hib) under different culture conditions
Heamophilus influenzae type-b (Hib) is a gram - negative pleomorphic bacterium that causes meningitis infections in children with the age of less than 5 years particularly in two years old infants. In the present study various isolates of Heamophilus influenzae from infants suspected to meningitis were collected, identified, characterized and were used throughout our experiments. Different cult...
متن کاملPhylogenetic Analysis of Beta-Glucanase Producing Actinomycetes Strain TBG-CH22 - A Comparison of Conventional and Molecular Morphometric Approach
Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...
