Abstract

Highlights: First report of a molecular investigation of M. ovis infection in goats from South America. M. ovis is highly prevalent in goats from northeastern Brazil, mainly in dairy animals. No association between M. ovis infection and the presence of ticks was observed. Anemia was a common find in Mycoplasma- infected animals. Abstract: Although Mycoplasma ovis (formerly Eperythrozoon ovis ) has been described in small ruminants worldwide, data on M. ovis in goats remain scarce. Accordingly, the aims of the present study were to i) determine the prevalence of hemoplasmas in goats, ii) identify the tick species parasitizing the animals, and iii) determine factors associated with infection in five dairy and three beef goat farms from the Paraíba State, northeastern Brazil. Blood samples were obtained from 402 goats. Samples were screened for hemoplasmas using a pan-hemoplasma PCR. The positive samples were confirmed by sequencing. An epidemiological questionnaire was given to each farm owner addressing age, gender, and presence of ticks. A total of 158/402 (39.3%) goats were positive for M. ovis by PCR. Sequencing of PCR positive samples has shown ≥99% identity with multiple M. ovis 16S rDNA sequences deposited in GenBank, including M. ovis isolates from humans. Dairy (OR = 2.15; 95% CI: 1.40–3.32%; P = 0.0004) and anemic goats (OR = 2.33; 95% CI: 1.51–3.71%; P = 0.0001) were more likely to be infected than beef and non-anemic animals, respectively. Amblyomma parvum (49/52, 94.23%) and Rhipicephalus microplus (3/52, 5.77%) were the tick species found parasitizing the animals, with no significant association between the presence of ticks and infection by M. ovis ( P = 0.1164). This is the first reportedly molecular detection of M. ovis infection in goats from South America. In conclusion, M. ovis is highly prevalent in goats from northeastern Brazil, mainly in dairy animals.
