Abstract: Mycoplasma ovis is an emerging zoonotic pathogen with a worldwide distribution and can cause mild to severe hemolytic anemia, icterus, and poor weight gain in animals. Although M. ovis has been described in small ruminants worldwide, data on M. ovis in sheep in Brazil is unknown. The objective of the present study was to present the first report of hemotropic mycoplasma (HM) in sheep from Brazil. We evaluated factors associated with this infection, such age group, tick presence, and anemia. Blood samples were … Show more

“…Although Souza et al (2019) detected a higher percentage of positivity to M. ovis in sheep from the state of Rio Grande do Sul, divergences on climate conditions, herd management, and employed PCR assays used may explain differences on hemoplasma prevalence rates between studies. Additionally, association between anemia (p = 0.5278) or the presence of ticks (p = 0.3089) and M. ovis infection were not found, similar to that reported in previous studies involving sheep (Rjeibi et al, 2015;Souza et al, 2019) and goats (Machado et al, 2017). Moreover, associations between anemia and EPG values > 500 were not found as well.…”

“…Herein, M. ovis was detected in 16.6% of the sampled sheep. Previous studies on the detection of M. ovis in Brazil have reported prevalence rates of 39.30% in goats (Machado et al, 2017), 40-87% in deer (Grazziotin et al, 2011a, b;André et al, 2020) and 78.8% in sheep (Souza et al, 2019).
