Epidemiological survey on Mycoplasma gallisepticum and M. synoviae by multiplex PCR in commercial poultry

Abstract: ABSTRACT.-Buim M.R., Mettifogo E., Timenetsky J., Kleven S. & Ferreira A.J.P. 2009 Mycoplasmas are important avian pathogens, which cause respiratory and joint diseases that result in large economic losses in Brazilian and world-wide poultry industry. This investigation regarding the main species of mycoplasmas, Mycoplasma gallisepticum (MG) and M. synoviae (MS), responsible for the above mentioned conditions, was carried out through PCR Multiplex analysis. One thousand and forty-six (1,046) samples of trachea… Show more

“…A recent study reports that the prevalence of MS and MG on farms in general is 72.7%. The results also indicate the dissemination of mycoplasmas among the farms surveyed, with an increase in the incidence of MS and a reduction in the incidence of MG among commercial poultry farms in Brazil (Buim et al 2009). Report that birds free of MS that are introduced onto a farm with a history of infection may become infected as well due to the perpetuation of the microorganism in the surrounding environment (Fiorentin et al 2002).…”

“…In Brazil, the frequency of infection by MS is greater than that by MG (Reis et al 1973, Mettifogo et al 2002, Buim 2005, Buim et al 2009). Moreover, the prevalence of MS in chickens has increased in the past twenty years (Balen & Fiorentin 1990).…”

“…Previous studies showed high prevalence of MS and IBV in Brazil. Buim et al (2009) found that 55% (16/29) of layer flocks were positive to MS and none to MG by PCR, while Sandri et al (2008) found 43.5% (20/46) positive to IBV by RT-PCR.…”

“…Embora psitacídeos desenvolvam frequentemente sinusite e conjuntivite, não são hospedeiros comuns e a patogenicidade de Mycoplasma nessas aves não está bem elucidada (Phalen et al 2006, Buim et al 2009). Consequentemente é importante sua investigação, já que a ave se torna portadora e imunossuprimida (Bradbury et al 1993), favorecendo ainda, o acometimento por outras enfermidades.…”
