Low haemoglobin (HGB) concentration was significantly associated with any hemoplasma and CMhm infection (χ2 = 9.21, df = 1, P = 0.002 and χ2 = 8.86 df = 1, P = 0.003, respectively) and low haematocrit (HTC) was associated with any hemoplasma infection (P = 0.004, OR = 0.34; 95% CI: 0.13–0.91). Here, CYGB is linked to infection.
