Rapid detection and differentiation of infectious bronchitis virus (IBV) involved in the disease outbreak is very important for controlling disease and developing new vaccines. In the present study, three regions of the genome of IBV vaccine and field isolates including S1 gene, gene 3 and nucleocapsid (N) gene along with 3' untranslated region (3' UTR) were amplified and subjected to restricti...

background: radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. however, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. in recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. the aim of the current study was to e...

Background and Objective: The healthy people’s fecal flora in the community represents a large potential reservoir. Therefore, the current study aimed to detect antibiotic resistance patterns and virulence factors in Klebsiella pneumoniae isolated from healthy volunteers’ feces. Materials and Methods: Three hundred and fifty stool specimens were collected from sales rep healthy individuals ref...

this is the first description of the polymorphisms of arylalkylamine-n-acetyltransferase (aa-nat) gene in indian goats with different reproductive traits (twinning percentage and age of sexual maturity). based on the important role of aa-nat in reproduction, it is considered as a possible candidate gene for this trait. two novel synonymous snps, c825t (exon2) and c1249t (exon3) were identified....

streptococcus agalactiae is acommensalorganism, but it may cause infection in susceptible hosts. the aim of this study was to evaluate pcr assay compared with conventional culture method for direct detection of streptococcus agalactiae . total of 203 paired low vaginal swabs were collected from women at 35-37 weeks of pregnancy from june 2013 through february 2014 for detection of streptococcus...

salinity is among important soil stresses adversely affecting the process of nitrogen (n) fixation in leguminous plants in different parts of the world. it has been indicated that salinity can inhibit the early stages of nodulation process between bacterium and the host plant including the exchange of signal molecules (nod gene inducers). there has not been any research regarding the effects of...

five common tetracycline resistance genes tet(a), tet(b), tet(m), tet(o) and tet(s) were studied by polymerase chain reaction in 100 bacteria isolated from iranian fish farms. in the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. nine isolates out of 46 aeromonas spp. contained either tet(a/m/s) resistant genes as follows: tet(a) in a. ...
