Nucleotide Sequence of Gene Encoding Capsid Protein VPI of Foot-and-Mouth Disease Virus / Type O1 Iran

Pathogenicity and haemagglutinin gene sequence analysis of Iranian avian influenza H9N2 viruses isolated during (1998–2001)

Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...

The vlhA gene sequencing of Iranian Mycoplasma synoviae isolates

Mycoplasma synoviae expressed variable lipoprotein haemagglutinin (VlhA) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. The aim of this study was sequencing Iranian M. synoviae isolates for the detection of nucleotide variation in the M. synoviae vlhA gene. Using oligonucleotide primers complementary to the single-copy conserved 5´ end...

Nucleotide Sequence Analysis of S1 Gene among Iranian Avian Infectious Bronchitis Viruses Isolated during 2001-2002

Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...

Identification and characterization of a NBS–LRR class resistance gene analog in Pistacia atlantica subsp. Kurdica

P. atlantica subsp. Kurdica, with the local name of Baneh, is a wild medicinal plant which grows in Kurdistan, Iran.  The identification of resistance gene analogs holds great promise for the development of resistant cultivars. A PCR approach with degenerate primers designed according to conserved NBS-LRR (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (R) gene...

Intraspecies Gene Variation within Putative Epitopes of Immunodominant Protein P48 of Mycoplasma agalactiae

P48 protein of Mycoplasma agalactiae is used to diagnose infection and was identified as potential vaccine candidate. According to the genetic nature of mycoplasma and variable sensitivity in P48-based serological diagnosis tests, intra species variation of P48 nucleotide sequence investigated in 13 field isolates of difference province of Iran along with three vaccine strains. Samples were col...
