Abstract Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, which can be acquired by oral contact and may cause severe health problems especially for pregnant (congenital toxoplasmosis) and immunocompromised patients. This study aimed to verify the diagnostic significance of hematological parameters and C-reactive protein (CRP) for toxoplasmosis acute detection. A case-control study was carried out between December 2017 and May 2018, in samples of convenience independent of age and sex. The case group was formed by 25 patients with positive anti-Toxoplasma gondii IgG/IgM antibody and the control group was formed by 21 patients with non-positive anti-Toxoplasma gondii IgG/IgM antibody. The results of the hematological parameters and CRP were analyzed in these patients. The patients with Toxoplasma gondii IgM antibody reagent showed higher lymphocytes counting and lower neutrophils counting than the control group. C-reactive protein levels were not different between the groups case and control. ROC curve analysis highlighted that the cut-off value of [ 32.00% for lymphocytes and \ 57.50% for neutrophils were able to produce specificity higher than 90% for IgM antibody detection. The Naı¨ve Bayes classifier was considered suitable (AUC & 0.700)

Introduction Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an intracellular parasite that is the unique specie able to produce the disease in all the hosts (Aguirre et al. 2019). Toxoplasmosis is acquired by oral contact with infecting

forms eliminated in feline feces, who contaminate the soil and the water (Escotte-Binet et al. 2019). The ingestion of raw or undercook meat contaminated with parasite cysts is an important way of acquiring the disease (Paraboni et al. 2019; Sroka et al. 2020), while the congenital transmission is also extensively reported and represents a public health problem (de Melo et al. 20
