Detecção de Mycoplasma spp. e Ureaplasma diversum em vacas com distúrbios reprodutivos

Abstract: Foram utilizadas 112 amostras de muco vulvovaginal, coletados de vacas com distúrbios reprodutivos, para pesquisa de Mycoplasma e Ureaplasma. Para isolamentos, foram usados meios específicos para micoplasmas (SP-4) e para ureaplasmas. PCR genérica, PCR específica para Mycoplasma bovis e nested-PCR em tubo único para Ureaplasma diversum foram realizados com os DNAs extraídos das amostras. Mycoplasma spp. e U. diversum foram detectados em 12,5 e 25,0%, respectivamente. A PCR genérica resultou em reações positiva… Show more

“…Infectious diseases may be associated with bacterial, viral or parasitic agents. In Brazil, these diseases may commonly include brucellosis, leptospirosis, infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD), ureaplasmosis (BUZINHANI et al, 2007) and neosporosis (MENDES et al, 2009). …”

“…De acordo com Buzinhani et al (2007), as infecções por micro-organismos da classe Mollicutes em animais possuem importância histórica e persistem interferindo na pecuária. São relatadas na literatura aproximadamente 200 espécies de Mollicutes, mas destas apenas algumas são consideradas patogênicas para os animais de produção, principalmente os micoplasmas (Frey 2002).…”

“…In the present study, the presence of mollicutes in vaginal mucus was assessed by cultured samples. However, using polymerase chain reaction (PCR) increased the detection of U. diversum from 25% to 37.5%, which is the percentage of positive samples from cows with reproductive disorders (Buzinhani et al 2007). This indicates that these bacteria may be present in a larger number of cows in the studied DFs.…”

“…Experimental infections and clinical isolates from commercial herds indicate that mollicutes are associated with GVV and significantly affect reproductive efficiency by increasing the number of days of open breeding and the number of repeat breeding cows (Nascimento et al 2005, Buzinhani et al 2007, Gambarini et al 2009). Besides the reproductive tract, U. diversum inhabits all mucosal membranes and causes a subclinical respiratory infection and bronchopneumonia in calves (Brown 2010).…”
