The counterpart of Escherichia coli initiation factor 3(IF-3) was isolated from Caulobacter crescentus, purified to homogeneity, and used in comparative studies on in vitro translation of RNA from the C. crescentus RNA phage Cb5 and of coliphage MS2 RNA. The two phage RNAs are similar in physical properties and analogous in genetic content. The factor, C-IF-3, substitutes for E. coli IF-3 and p...

While translational read-through of stop codons by suppressor tRNAs is common in many bacteria, archaea and eukaryotes, this phenomenon has not yet been observed in the α-proteobacterium Caulobacter crescentus. Based on a previous report that C. crescentus and Escherichia coli tRNA(His) have distinctive identity elements, we constructed E. coli tRNA(His) CUA, a UAG suppressor tRNA for C. cresce...

Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...

A study was done to characterize the shedding of foodborne pathogenic bacteria by Caenorhabditis elegans, evaluate the persistence of worm populations cocultured with foodborne pathogens, and determine if C. elegans disperses ingested pathogens in soil as a result of shedding. Escherichia. coli O157:H7, Salmonella enterica serotype Poona, and Listeria monocytogenes, as well as E. coli OP50, a n...

background: the aim of this study was to determine the prevalence of virulence-associated genes and enterobacterial repetitive intergenic consensus pcr (eric-pcr) analysis of campylobacter spp. isolated from children with diarrhea in iran. methods: a total of 200 stool specimens were obtained from children under 5 years during july 2012 to july 2013. detection of c. jejuni and c. coli was perfo...

Fluorescent amplified fragment length polymorphism (FAFLP) analysis was applied to 276 Campylobacter jejuni strains and 87 Campylobacter coli strains isolated from humans, pigs, cattle, poultry, and retail meats to investigate whether certain FAFLP genotypes of C. jejuni and C. coli are associated with a particular host and to determine the degree of association between FAFLP-defined genotypes ...

introduction: hepatitis c virus (hcv) infection is a major public health problem which influences about 170 million people worldwide. different types of vaccines have been designed using hcv structural proteins to control the viral infection. the core nucleocapsid protein is one of the most conserved proteins and a desirable target for hcv vaccines, especially the protein-based vaccines. in cur...
