چکیده

The “in house” PCR method and four commercial PCR kits (designed symbolically as A, B, C, and D) for the detection of Mycoplasma synoviae (MS) in tracheal swabs of infected experimentally SPF chickens were compared. The chickens were inoculated intranasally with 1x10 colour change unit (cfu)/mL of ATCC reference MS strain, and at 4, 7, 14, 28, and 35 d post infection (d.p.i.), the tracheal samples were collected and examined. The methods showed different sensitivities. The commercial test C seemed to be less sensitive (0.5 ng/mL) than the rest of the methods (50 pg/mL). Only the “in house” method and commercial test D detected MS DNA from 7 to 14 d.p.i.; no satisfactory results were obtained with the other kits. Since the methods have shown different sensitivity, their suitability for MS detection seems to be limited.

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...

Molecular detection of Mycoplasma synoviae from backyard and commercial turkeys in some parts of Iran

M. synoviae (MS) is an economically important pathogen and the major cause of airsacculitis and infectious synovitis in turkeys. Infection with this pathogen may remain asymptomatic but can render infected birds susceptible to secondary infections. This study was carried out for the molecular detection of MS infection in commercial and backyard turkey flocks in Tehran, Semnan, Isfahan, Qazvin, ...

Molecular characterization of Mycoplasma synoviae isolates from commercial chickens in Iran

Detection of Mycoplasma synoviae (MS) by culture and polymerase chain reaction (PCR) has been reported from commercial chicken farms in different provinces of Iran. In some reports the phylogenetic analysis of MS isolates based on 16S rRNA and variable lipoprotein hemagglutinin (vlhA) genes have been carried out. The PCR product containing partial 16S rRNA genes of Iranain isolates was sequence...
