Objective(s) Some properties of neuraminidase produced by Pseudomonas aeruginosa PAO1 growth in a defined medium (BHI) were examined and evaluated for its features. Materials and Methods The obtained supernatant enzyme of P. aeruginosa PAO1 cultures was used in a sensitive fluorometric assay by using 2'-(4-methylumbelliferyl) a-D-N acetylneuraminic acid as substrate. As hydrolyzing MUN with ...

The urgent need of neuraminidase inhibitors (NI) has provided an impetus for understanding the structure requisite at molecular level. Our search for selective inhibitors of neuraminidase has led to the identification of pharmacophoric requirements at various positions around acyl thiourea pharmacophore. The main objective of present study is to develop selective NI, with least toxicity and dru...

Background: Sialic acid is a component of serum that is elevated in diseases such as diabetes and certain malignancies.  The normal range of SSA concentration and serum neuraminidase activity in different populations are varied, probably due to racial differences. Objective: The purpose of the present study was to obtain the average SSA concentration and serum neuraminidase activity, in an Iran...

background and objectives: the properties of neuraminidase produced by p. aeruginosa strain pao1 during growth in a defined medium (bhi) was examined and compared with some neuraminidase features of k. pneumoniae in this investigation. materials and methods: the enzyme was isolated from concentrated culture supernatants of p. aeruginosa which was used in a sensitive fluorometric assay by using ...

To detect the presence of infectious bronchitis virus (IBV) in infected allantoic fluid (AF) of SPF embryonated eggs rapid hemagglutination (HA) activity after treatment with neuraminidase enzyme was used. Twenty IBV suspected materials were inoculated in SPF embryonated eggs via chorioallantoic cavity. Harvested AFs were treated with neuraminidase enzyme and the presence of IBV was detected by...
