Ovine babesiosis is an endemic tick-borne disease of small ruminants in the Middle East, European, and some African and Asian countries, including Turkey. This study assessed whether the endemic status of this disease was stable or instable, which is important for disease control efforts. For this aim, 4115 sheep blood samples were collected from 81 cities in the seven geographical regions of Turkey. The diagnosis of Babesia ovis was made using microscopic and serological techniques. Thin blood smears were prepared from anticoagulated venous blood. Serum samples were screened for specific antibodies using an enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent antibody test (IFAT). Recombinant Babesia ovis secreted antigen 1 (rBoSA1) was used in the ELISA. The antigen slides used in the IFAT were prepared from the B. ovis-infected blood at a high level of parasitemia (5 %). The animals were divided into three groups according to their age: group I (one to six months), group II (6-12 months), and group III (older than one year). The endemic status of B. ovis was determined according to the inoculation rate (h value) calculations. Babesia spp. merozoites were observed in 40 (0.97 %) of the slides. Seropositivity rates were 29.89 % (1230/4115) and 49.16 % (2023/4115) by the ELISA and IFAT, respectively. According to the IFAT results, 31.7 %, 33.6 %, and 52.8 % of the animals were seropositive in groups I, II, and III, respectively. The inoculation rates of the animals indicated that the endemic status of ovine babesiosis was mostly instable throughout the country. Endemic stability was found only in group I from four regions (Central Anatolia, Eastern Anatolia, Aegean, and Mediterranean). Based on these results, the risk of clinical infection due to tick infestation was high when the maternal immunity and non-specific age resistance weakens or disappears. Thus, vaccination is needed to protect sheep against B. ovis infections in Turkey.

Piroplasmosis is an important tick-borne disease in several regions, and can lead to significant economic animal production losses. The current study aimed to systematically examine the incidence of bovine piroplasmosis in Kashgar, Xinjiang, to provide baseline data for the effective prevention and control of this disease among bovines in the region. A total of 1403 bovine blood samples from 12 sampling points were screened via PCR with universal Piroplasma primers targeting the 18S rRNA locus and specific Theileria annulata primers targeting the cytochrome b (COB) gene.

Small ruminant babesiosis remains a neglected disease despite causing significant economic losses to sheep and goat herds in many regions around the world. The pathogenesis and clinical manifestations of ovine babesiosis are well-known, but there is a lack of information regarding caprine babesiosis. Since the discovery of the first Babesia spp.

However, the impact of on goats has remained uncertain, prompting us to investigate its pathogenicity in caprine hosts. Experimental infections using -infected blood inoculation and infected tick infestation, were conducted on spleen-intact (n=5) and splenectomized (n=5) goats.
