Genetic diversity of emerging hemotropic mycoplasmas in domestic pigs from Brazil

Abstract: Mycoplasma suis and Mycoplasma parvum bind strongly to erythrocytes and may cause clinical hemoplasmosis in swine, affecting several age groups. Mycoplasma spp. infected animals may be asymptomatic carriers and/or show nonspecific clinical signs.In Brazil, information on genetic diversity associated with porcine hemoplasmas (PH) has not been described yet. Therefore, this study has aimed to detect, quantify and characterize the genetic diversity of PH in finishing pigs from technified farms in the state of Goi… Show more

“…Sows, which are older animals, exhibited a higher positive percentage (63.2%) compared with nursery/growing pigs (5.0%). Similar to the results of other studies, the frequency of infection was higher in older animals, including finishing pigs, sows and boars, although porcine haemoplasmas were detectable in pigs of all ages (Fu et al., 2017; Gatto et al., 2019; Sonalio et al., 2021). Also, the association between pig ages and haemoplasma infection has not been well investigated.…”

“…Also, the association between pig ages and haemoplasma infection has not 2019) stated that chronic infection characterized by a low level of parasitaemia seems to be responsible for the differences in the prevalence of M. suis, rather than pig ages. Animals having low parasitaemia may be undetectable by less sensitive diagnostics, such as conventional PCR (Gatto et al, 2019;Sonalio et al, 2021). Apart from that, selection bias may affect the frequency detected during blood collection procedures.…”
