Abstract
Babesia bovis and B. bigemina are the most common tick-borne parasites that cause bovine babesiosis which effects livestock production, leading to economic losses in tropical and subtropical areas of the world. The aims of this study were to determine the molecular detection, genetic diversity and antigenicity prediction of B. bovis based on spherical body protein 2 (sbp-2) gene and B. bigemina based on rhoptry-associated protein 1a (rap-1a) gene in cattle in Thailand. By PCR assay, the molecular detection of B. bovis and B. bigemina infection revealed levels of 2.58% (4/155) and 5.80% (9/155), respectively. The phylograms showed that B. bovis sbp-2 and B. bigemina rap-1a sequences displayed 5 and 3 clades with similarity ranging between 85.53 to 100% and 98.28 to 100%, respectively, when compared within Thailand strain. Diversity analysis of sbp-2 and rap-1a sequences showed 18 and 4 haplotypes, respectively. The entropy analysis illustrated 104 and 7 polymorphic sites of sbp-2 and rap-1a nucleic acid sequences, respectively, while those of sbp-2 and rap-1a amino acid sequences showed 46 and 4 high entropy peaks, respectively. Motifs analysis exhibited the distribution and conservation among sbp-2 and rap-1a sequences. The continuous and discontinuous B-cell epitopes have also been evaluated in this work. Therefore, our findings may be used to ameliorate the understanding inputs of molecular phylogeny, genetic diversity and antigenicity of B. bovis and B. bigemina Thailand stains.

Molecular Reports of Ruminant Babesia in Southeast Asia. Pathogens 2022; 11:pathogens11080915. [PMID: 36015035 PMCID: PMC9415187 DOI: 10.3390/pathogens11080915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 08/11/2022] [Accepted: 08/11/2022] [Indexed: 11/16/2022] Open
Abstract
The protozoon Babesia is a blood parasite transmitted by hard ticks and commonly parasitizes ruminants such as cattle, buffaloes, goats, and sheep. Babesiosis, the disease caused by Babesia infection, has been considered a potential threat to ruminant production due to the grave and enormous impact it brings. About 125 million ruminants are at risk of babesiosis in Southeast Asia (SEA), a region composed of 11 countries. In recent decades, molecular-based diagnostic platforms, such as polymerase chain reaction (PCR) assays, have been a reliable and broadly employed tool in Babesia detection. In this article, the authors compiled and summarized the molecular studies conducted on ruminant babesiosis and mapped the species, including B. bovis, B. bigemina, B. ovata, Babesia sp. Mymensingh, Babesia sp. Hue, and B. ovis, and determined the host diversity of ruminant Babesia in SEA.

Ticks Tick Borne Dis 2021; 12:101783. [PMID: 34274575 DOI: 10.1016/j.ttbdis.2021.101783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 06/08/2021] [Accepted: 06/24/2021] [Indexed: 10/20/2022]
Abstract
Babesia bigemina is an intra-erythrocytic apicomplexan protozoon which causes an acute as well as chronic disease in cattle and is transmitted by ixodid ticks throughout the world. Due to low sensitivity of microscopy for detection of the parasite, there is a need for developing effective diagnostic tests that can be used to identify carrier animals in endemic areas. In the present study, C-terminal fragment of rhoptry associated protein-1 (RAP-1/CT) and 200 kDa merozoite protein (P200/CT) of B. bigemina were cloned into pET-32a(+) expression vector and expressed in Escherichia coli as thioredoxin-fusion proteins for use in an indirect ELISA. The rRAP-1/CT and rP200/CT showed no cross reactivity with plasma from cattle infected with other common parasites namely Theileria annulata, Trypanosoma evansi, Cryptosporidium parvum and Anaplasma marginale in the standardized ELISA. Examination of 116 blood samples collected from cattle suspected for haemoprotozoan infections revealed that 17 (14.6%), 46 (39.6%), 52 (44.8%) and 53 (45.7%) were positive for B. bigemina by microscopy, nested PCR, rRAP-1/CT based and rP200/CT based indirect ELISA, respectively. The diagnostic sensitivities of rRAP-1/CT and rP200/CT indirect ELISAs were 97.8% and 91.3%, while the diagnostic specificities were 90% and 84.3%, respectively, when nested PCR was taken as a reference test. An almost perfect agreement (Kappa value -0.859) between rRAP-1/CT ELISA and nested PCR results, and a substantial agreement (Kappa value -0.737) between rP200/CT ELISA and nested PCR were noticed. The findings of the present study suggest that rRAP-1/CT is a better diagnostic candidate antigen than rP200/CT for diagnosis of B. bigemina infection and it may be used in an ELISA for surveillance or diagnosis of B. bigemina infection in bovines.

Abstract
Detection of bovine Babesia spp. and Anaplasma marginale is based on the reading of Giemsa-stained blood or organ smears, which can have low sensitivity. Our aim was to improve the detection of bovine Babesia spp. and A. marginale by validating a multiplex PCR (mPCR). We used 466 samples of blood and/or organs of animals with signs and presumptive autopsy findings of babesiosis or anaplasmosis. The primers in our mPCR amplified the rap-1a gene region of Babesia bovis and B. bigemina, and the msp-5 region of A. marginale. We used a Bayesian model with a non-informative priori distribution for the prevalence estimate and informative priori distribution for estimation of sensitivity and specificity. The sensitivity and specificity for smear detection of Babesia spp. were 68.6% and 99.1%, and for A. marginale 85.6% and 98.8%, respectively. Sensitivity and specificity for mPCR detection for Babesia spp. were 94.2% and 97.1%, and for A. marginale 95.2% and 92.7%, respectively. Our mPCR had good accuracy in detecting Babesia spp. and A. marginale, and would be a reliable test for veterinarians to choose the correct treatment for each agent.

Abstract
Ticks are obligate hematophagous ectoparasites considered as vectors of animal diseases, having a huge economic impact in cattle industry. Babesia spp. are tick-borne pathogens that cause a disease called babesiosis in a wide range of animals and in humans. Control of tick infestations is mainly based on the use of acaricides, which have limited efficacy reducing tick infestations, mostly due to wrong usage, and is often accompanied by the selection of acaricide-resistant ticks, environmental contamination, and contamination of milk and meat products. Vaccines affecting both vector and pathogens constitute new control strategies for tick and tick-borne diseases and are, therefore, a good alternative to chemical control. In this chapter we describe the identification of Rhipicephalus (Boophilus) annulatus genes differentially expressed in response to infection with B. bigemina by using suppression-subtractive hybridization (SSH), which allows the identification of differentially expressed genes. The results of the SSH studies are validated by real-time reverse transcription (RT)-PCR. Functional analyses are conducted by RNAi on selected R. annulatus genes to determine their putative role in B. bigemina-tick interactions. Gathered data may be useful for the future development of improved vaccines and vaccination strategies to control babesiosis.

Abstract
A total of 250 blood samples were collected from clinically healthy cattle in five provinces of Philippines. DNA was extracted from the samples and analyzed by nested PCR assays for an epidemiological survey of Babesia bovis and Babesia bigemina infections. Out of the 250 samples, 27 (10.8%) and 16 (6.4%) were positive for B. bovis infection and B. bigemina infection, respectively. Mixed infections were detected in a total of 4 samples (1.6%). Our data provide baseline information regarding the epidemiology of B. bovis and B. bigemina infections in cattle in Philippines, which can be utilized in developing proper strategies for disease control and management.

Abstract
Although Babesia bovis and Babesia bigemina infections cause economic losses in the cattle industry in northern Thailand, there is inadequate information on Babesia isolates present in the area. Therefore, to determine the prevalence and genetic relationship between Babesia isolates, we screened 200 blood samples of cattle from Chiang Rai, Chiang Mai, and Lumpang provinces of northern Thailand. A nested polymerase chain reaction using primers targeting B. bovis spherical body protein 2 (BboSBP2) and B. bigemina rhoptry-associated protein 1a (BbiRAP-1a) genes revealed a prevalence of 12 and 21 % for B. bovis and B. bigemina, respectively, while that of mixed infections was 6.5 % samples. The prevalences of B. bovis in Chiang Rai, Chiang Mai, and Lumpang were 9.5, 3.7, and 25.5 %, respectively. For B. bigemina, the prevalences were 15.8, 12.9, and 39.2 % in Chiang Rai, Chiang Mai, and Lumpang, respectively. Mixed infections with B. bovis and B. bigemina were 6.3 % in Chiang Rai, 1.9 % in Chiang Mai, and 13.7 % in Lumpang. The identical sequences of either BboSBP2 gene or BbiRAP-1a gene were shared among the Babesia isolates in the three provinces of northern Thailand. Further analysis using the internal transcribed spacer gene revealed at least four genotypes for B. bovis and five genotypes for B. bigemina in northern Thailand, while the sequences present great genetic diversities in the different isolates. Overall, we have demonstrated a high prevalence and polymorphism of Babesia parasites in northern Thailand calling for the need to design effective control programs for bovine babesiosis.

Abstract
Babesiosis is a disease with a world-wide distribution affecting many species of mammals principally cattle and man. The major impact occurs in the cattle industry where bovine babesiosis has had a huge economic effect due to loss of meat and beef production of infected animals and death. Nowadays to those costs there must be added the high cost of tick control, disease detection, prevention and treatment. In almost a century and a quarter since the first report of the disease, the truth is: there is no a safe and efficient vaccine available, there are limited chemotherapeutic choices and few low-cost, reliable and fast detection methods. Detection and treatment of babesiosis are important tools to control babesiosis. Microscopy detection methods are still the cheapest and fastest methods used to identify Babesia parasites although their sensitivity and specificity are limited. Newer immunological methods are being developed and they offer faster, more sensitive and more specific options to conventional methods, although the direct immunological diagnoses of parasite antigens in host tissues are still missing. Detection methods based on nucleic acid identification and their amplification are the most sensitive and reliable techniques available today; importantly, most of those methodologies were developed before the genomics and bioinformatics era, which leaves ample room for optimization. For years, babesiosis treatment has been based on the use of very few drugs like imidocarb or diminazene aceturate. Recently, several pharmacological compounds were developed and evaluated, offering new options to control the disease. With the complete sequence of the Babesia bovis genome and the B. bigemina genome project in progress, the post-genomic era brings a new light on the development of diagnosis methods and new chemotherapy targets. In this review, we will present the current advances in detection and treatment of babesiosis in cattle and other animals, with additional reference to several apicomplexan parasites.

Abstract
SUMMARYMolecular detection ofBabesiaspecies in apparently healthy cattle within an endemic region was carried out in order to determine the prevalence of carriers and the geographical distribution ofBabesia bigeminaandBabesia bovisin Maputo Province, Mozambique. Samples from 477 animals at 5 localities were analysed using 2 techniques, the semi-nested hot-start PCR and the reverse line blot (RLB) assay. With the semi-nested hot-start PCR, detection ofB. bigeminaranged between 30% and 89%, and ofB. bovisbetween 27% and 83%. The RLB assay was comparatively less sensitive in this study and detection ofB. bovisranged from 0% to 17%, andB. bigeminawas not detected at all by this technique. Analysis of new sequences of the 18S rRNA gene revealed that the currentB. bigeminaRLB probe is not specific for the identification of isolates in Mozambique. The RLB assay, however, resulted in the detection of 8 other haemoparasite species belonging to the generaBabesia,Theileria,AnaplasmaandEhrlichia. 18S rRNA gene sequences from theTheileriaspp. were identified, and a phylogenic tree constructed with these sequences yielded a heterogeneousT. mutans-like group. In conclusion, infection withB. bigeminaandB. bovisis endemic in Maputo Province, but rates of transmission vary. Furthermore, mixed infections with the haemoparasites responsible for several tick-borne diseases in cattle are common in Mozambique.
