Abstract

Hemoplasma "Candidatus Mycoplasma haemobos" infections in cattle have been reported in East Asia, Europe, and South America, whereas same cases were documented in buffalo and cattle in Southern China. From April 2018 to May 2018, a mycoplasma epidemic was reported in the mountainous area of central China; Boophilus microplus has also been documented, causing severe haematuria in goats and sheep. The infected animals slowly recovered after diminazene aceturate and praziquantel treatment. To determine whether the hemoplasma caused this infection, 67 blood samples (42 from goats, 25 from sheep) and 132 B. microplus samples were collected for PCR and sequence analysis. The results showed that 19 out of the 42 goat blood samples, 10 out of the 25 sheep blood samples, and 70 out of the 132 B. microplus samples (53%) tested positive for "C. M. haemobos". This study provides molecular evidence of "C. M. haemobos" infections in goat and sheep, and that B. microplus harbours "C. M. haemobos".

Keywords: Boophilus microplus; China; goat; sheep; “Candidatus Mycoplasma haemobos”.
