Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida  isolates...

Introduction: Mycoplasmas are one of the most serious contaminants of cellular cultures and their biological productions. Mycoplasma diagnosis is conducted on the basis of culture and molecular methods. These methods are different from each other in terms of accuracy, reliability, and sensitivity. This study aimed to trace the mycoplasma contaminations in culture samples using 16S rRNA specific...

in this study, to increase information about the relationship between caprine and ovine isolates of pasteurella multocida, 16s rrna gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. also, capsular type and toxagene presentation was studied in this paper. all isolates, except one, belong to capsular type a, and toxa+ strain distributed among strains were isolated from both...

A bacterial strain, designated BzDS03 was isolated from water sample, collected from Dal Lake Srinagar. The strain was characterized by using 16S ribosomal RNA gene and 16S-23S rRNA internal transcribed spacer region sequences. Phylogenetic analysis showed that 16S rRNA sequence of the isolate formed a monophyletic clade with genera Escherichia. The closest phylogenetic relative was Escherichia...

Background: Phenol is an aromatic pollutant in industrial wastes that in combination with salts is highly toxic for all forms of life. Phenol elimination is the foremost challenge to meet the goal of pollutant-free environment. Objective: The present study was carried out to isolate phenol degrading bacteria which can degrade phenol under saline conditions and...

Correspondence between two distinct genetic traits, 16S rRNA gene sequences and repetitive element-sequence-based BOX-PCR DNA fingerprints, and antibiotic inhibition and resistance phenotypes was explored for a spatially explicit sample of Streptomyces from a prairie soil. There was no correspondence between 16S rRNA gene sequence groups and antibiotic phenotypes. However, 16S rRNA gene sequenc...

concentrations of zn, cu, cr, cd, pb and fe in surface marine sediments of the southern coast of sfax were studied in order to understand current metal contamination at the outlet of a mixed industrial and domestic wastewater effluent discharged into the seawater since 1953. we found that heavy metal concentrations (mg/kg dry weight) in surface marine sediments varied from 42 to 391 for zn, 15 ...
