“…In our study, the prevalence of theileriosis was found to be 2.01% in large ruminants and 0.34% in small ruminants. In comparison, a study conducted in Lahore, Punjab, reported a higher prevalence of 11.2% in large ruminants [53,54], whereas in the Malakand division, the prevalence was 3.44% in small ruminants and 6.21% in large ruminants [54]. For babesiosis, we reported a prevalence of 2.09% (with 12 positives out of 573 samples) in large ruminants, with higher prevalence (13.89%) again reported in other work across three districts in Punjab, Pakistan [55].…”

Tick-borne diseases affecting domestic animals and humans have increased globally in recent years. Pakistan, in particular, faces a significant economic threat from ticks, where two specific species, Rhipicephalus microplus and Hyalomma anatolicum, act as vectors for various pathogens such as piroplasma, Anaplasma, Ehrlichia, and Rickettsia that pose a significant burden on livestock production in the country. To better understand the risk that tick-borne pathogens (TBPs) pose to livestock in Pakistan, we conducted a cross-sectional study of the occurrence, diversity, and coinfection of these pathogens in small and large ruminants owned by small farms as well as in ticks collected from these animals. We collected blood samples from 224 cattle, 224 buffalo, 69 goats, and 56 sheep, gathered from 112 farms located in seven districts of Punjab, one of Pakistan’s largest province. In addition, we collected a total of 476 ticks attached to these animals. Based on the identification of tick species through morphology and sequence analysis of the 16S rRNA and cytochrome c oxidase subunit 1 (cox1) gene, we confirmed that the most commonly collected tick species were Rh. microplus (38.65% of all individuals), H. anatolicum (31.93%), and Rh. decoloratus (8.40%). Notable pathogens detected in the collected ticks included Theileria annulata (18.4% prevalence), Anaplasma ovis (15.79%), A. centrale (13.16%), and Rickettsia slovaca (13.16%). In blood samples, the most frequently detected pathogens were T. annulata (n = 8), Babesia bovis (n = 7), A. centrale (n = 6), and B. bigemina (n = 5). In some cases, both cattle and buffaloes were found to be coinfected with B. bovis, T. annulata, and A. centrale. These findings provide valuable insights into the circulation of TBPs in livestock and highlight the need for further research on the epidemiological risk that these pathogens pose to ruminants in Pakistan.

“…The prevalence of piroplasma infection in cattle and buffalo in Ismailia, Egypt, according to the current study was 23.9 and 19.5 %, respectively. The findings showed that various researches have noted the varied frequencies of piroplasmosis among cattle and buffalo (Mohsin et al, 2022). The majority of research found that the infection in cattle was higher than in buffalo.…”

Tick-borne diseases (TBDs) are important factors that affect the development of animal husbandry worldwide, in both tropical and subtropical area. The aim of this study is to investigate the prevalence of the Piroplasma species in both Al Gabal al Akhder region in northeastern Libya and Ismailia, Egypt. Blood samples were collected randomly from 748 apparently healthy animals from various localities in Libya and Egypt during the period extending from January 2020 to January 2021. Giemsa-stained thin blood films were used for direct microscopy, conventional PCR was used for molecular identification of the samples. The results showed the prevalence of Piroplasma in Egypt was 23.9% in cattle and 19.5%in buffaloes, while in Libya the cattle was 27.6%, 31% in sheep, and 21% in goats. Real-time PCR in the diagnosis of blood parasites may give better results than conventional PCR.

“…Malignant theileriosis can also be passed down from parent to offspring through vertical transmission (Moudgil et al 2023). The prevalence of the disease peaks during summer months due to favorable ecological conditions and climatic stress, which promote the breeding and proliferation of ticks (Mohsin et al 2022; Irfan et al 2023). Small ruminants, like sheep and goats, are especially vulnerable to tick infestations, resulting in tick-borne blood protozoan diseases such as anaplasmosis, babesiosis, and theileriosis.…”

Ovine theileriosis represents a significant threat to both animal welfare and global agricultural productivity, particularly impacting economically disadvantaged farmers. Vector-borne haemoparasitic diseases like theileriosis have a profound effect on the health of livestock, leading to increased illness and mortality, especially in the coastal regions of Odisha. This research aimed to investigate and comprehend the prevalence, clinical manifestations, hematological and biochemical parameters, as well as molecular aspects of theileriosis in sheep from Kendrapada. Among 148 blood samples collected from Kendrapada sheep across four blocks, 13% tested positive for theileriosis, indicating a notable prevalence. The prevalence rate was highest among sheep aged 1–4 years (19%), followed by those younger than 1 year (17.9%) and older than 4 years (13.3%). Female sheep exhibited a higher prevalence (19%) compared to males (16%). Block-wise prevalence was highest in Aul (27.9%), followed by Marshaghai (19.4%), Kendrapada (16.1%), and Derabish (5.88%). Hematological analysis revealed deviations in parameters such as hemoglobin, total erythrocyte count, total leukocyte count, and mean corpuscular volume, while packed cell volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and differential leukocyte count remained within normal ranges. Significant differences (P < 0.05) were observed in various parameters between Theileria-positive and negative sheep. However, there were no substantial variations noted among different age groups and genders of Theileria-positive sheep. PCR analysis identified an overall incidence of theileriosis at 17.57% in the study population, with sequences closely resembling Theileria luwenshuni isolates. This study confirms the high variability of the 18S small subunit rRNA gene among Theileria spp.
