Abstract
The present study aimed to investigate the molecular epidemiology, risk factors, and haemato-biochemical changes in anaplasmosis in Indian dromedary camels. Blood samples collected from 103 camels were analysed using blood smear examination and semi-nested PCR based on the 16s rRNA gene to diagnose anaplasmosis. The prevalence of anaplasmosis was estimated to be 42.72% (95% CI: 33.59-52.37) by PCR assay and 16.5% (95% CI: 10.47-24.95%) by blood smear examination. Phylogenetic analysis of six partial sequences of 16s rRNA gene obtained in the present study indicated the involvement of multiple Anaplasma species, including A. marginale and A. platys, showing genetic similarity with cattle strains. A novel genotype related to A. camelii/A. cinensis/A. platys group was also identified. Hemato-biochemical examination revealed mild anaemia, increased serum urea nitrogen and creatinine levels, and decreased total protein and albumin levels in Anaplasma-positive animals. The infections were largely subclinical in nature, except in one camel that revealed fever, inappetence, and pale mucous membrane and responded well to treatment with oxytetracycline. To our knowledge, this is the first molecular study on camel anaplasmosis in India, indicating a high prevalence of infection and involvement of multiple Anaplasma species with potential risk for interspecies transmission.

Molecular and serological detection of Anaplasma spp. in small ruminants in an area of Cerrado Biome in northeastern Brazil. Ticks Tick Borne Dis 2024; 15:102254. [PMID: 37989016 DOI: 10.1016/j.ttbdis.2023.102254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 08/15/2023] [Accepted: 09/10/2023] [Indexed: 11/23/2023]
Abstract
Anaplasmosis, caused by bacteria of the genus Anaplasma, is an important tick-borne disease that causes economic losses to livestock farms in many countries. Even though Anaplasma spp. have been detected in goats and sheep worldwide, few studies investigate the occurrence and genetic identity of these agents in small ruminants from Brazil. Thus, this work aimed to detect and determine the genetic identity of Anaplasma spp. in small ruminants from the Baixo Parnaíba region, state of Maranhão, northeastern Brazil. For this purpose, blood samples were collected from 161 animals (91 goats; 70 sheep) from 4 municipalities in the Baixo Parnaíba region. Sheep and goat serum samples were subjected to recombinant membrane surface protein (MSP5)-based iELISA. Whole blood samples were subject to DNA extraction and molecular diagnosis using PCR assays for Anaplasma spp. targeting msp1β, msp1α, 16S rRNA and msp4 genes. Positive samples were sequenced and then subjected to Anaplasma marginale msp1α genetic diversity analysis and phylogenetic inferences based on the 16S rRNA and msp4 genes. The serological survey detected the presence of anti-A. marginale IgG antibodies in 18 animals (11.1%): 2.9% (2/70) sheep and 17.4% (16/91) goats. Anaplasma marginale DNA was detected in 2 goats (1.2%) using qPCR based on the msp1β gene. Two distinct A. marginale msp1α strains, namely α β and α β ΓγΓγΓγΓγ were found in the infected goats, each one found in a different animal, both belonging to the H genotype. Phylogenetic analysis based on the 16S rRNA gene showed the sequences positioned in three different clades and grouped with sequences from 'Candidatus Anaplasma boleense', A. platys and A. marginale. Phylogenetic inferences based on the msp4 gene positioned the sequence variants in the A. marginale clade. The present work represents the first molecular detection of sequence variants phylogenetic associated to 'Candidatus Anaplasma boleense' and A. platys and α β and α β ΓγΓγΓγΓγ in goats from Brazil.

Artificial Feeding of Ornithodoros fonsecai and O. brasiliensis (Acari: Argasidae) and Investigation of the Transstadial Perpetuation of Anaplasma marginale. Microorganisms 2023; 11:1680. [PMID: 37512853 PMCID: PMC10385771 DOI: 10.3390/microorganisms11071680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 06/21/2023] [Accepted: 06/26/2023] [Indexed: 07/30/2023] Open
Abstract
Anaplasma marginale is a Gram-negative, obligate intraerythrocytic bacterium that causes bovine anaplasmosis. While hard ticks of the genera Dermacentor and Rhipicephalus can be biological vectors, transmitting this pathogen via saliva during blood meals, blood-sucking insects, and fomites play a role as mechanical vectors. Little is known about the interaction between Anaplasma marginale and Argasidae ticks. Among soft ticks, Ornithodoros fonsecai (Labruna and Venzal) and Ornithodoros brasiliensis Aragão inhabit environments surrounding localities where many cases of bovine anaplasmosis have been reported. Ticks of the species O. fonsecai parasitize bats, while O. brasiliensis can parasitize different vertebrate species. Therefore, the present study aimed to feed third-instar nymphs artificially (N3) of O. fonsecai and O. brasiliensis using blood samples obtained from a calf naturally infected with A. marginale and rabbit blood added to A. marginale-containing bovine erythrocytes, to investigate the ability of these nymphs to acquire, infect and transstadially perpetuate this agent. For the artificial feeding system, adapted chambers and parafilm membranes were used. Nymphs of both tick species were submitted to different replications weighed before and after each feeding. Blood samples and molted ticks were submitted to DNA extraction, quantitative real-time PCR for the msp1β gene to detect A. marginale DNA, while a semi-nested polymerase chain reaction for the msp1α gene was performed for genotyping. Using calf blood naturally infected with A. marginale, among the three artificial feeding replications performed with O. fonsecai and O. brasiliensis nymphs, the DNA of A. marginale was detected in both nymphs after 30-50 days of molting. For artificial feeding with rabbit blood added to bovine erythrocytes containing A. marginale, the DNA of this pathogen was also detected in both nymph species. As for the assay for the msp1α gene, strains were found Is9; 78 24-2; 25; 23; α; and β. It was concluded that nymphs (N3) of O. fonsecai and O. brasiliensis could feed artificially through a parafilm membrane using blood from calves and rabbits infected by A. marginale. The DNA of A. marginale was detected in nymphs fed artificially of both tick species studied after molt. However, further studies are needed to confirm transstadial perpetuation in other instars and their host transmission capacity.

Abstract
Hemoprotozoal diseases are significant health concerns in small ruminants. The present study was conducted to identify and characterize the species of Theileria and Anaplasma in sheep and goats located in different districts of North Gujarat, India. A total of 226 (Banaskantha = 175, Patan = 26, and Bhuj = 25) blood samples were collected from sheep (n = 78) and goats (n = 148), and 46 ticks were collected and identified from sheep and goats. PCR assays were carried out using genus and species-specific primers for Theileria targeting 18S rRNA locus and for Anaplasma targeting the msp5 gene. Overall, 37.2% sheep (29/78) and 10.8% of goats (16/148) were positive for Theileria by PCR, whereas 15.4% of sheep (12/78) and 25.7% goats (38/148) were positive for Anaplasma infection. Moreover, mixed infection was found in 4.4% (10/226) of sheep and goats by PCR. Sanger sequencing of Theileria and Anaplasma positives revealed a high similarity to T. ovis and A. ovis using NCBI blast, respectively. Phylogenetic analyses revealed that the Anaplasma spp. DNA sequences belonged to the A. ovis group and closely associated with the A. ovis nucleotide sequence strain Haibei isolated in China from sheep (GQ483471). The phylogenetic analysis based on the SSU rRNA locus revealed that the Theileria ovis DNA sequences belonged to the T. ovis group and closely related to MW440586 isolated in Kerala, India, from a goat. The majority of ticks (91.3%) were identified as Hyalomma. In conclusion, Theileria ovis and Anaplasma ovis were commonly identified species in sheep and goats and transmitted mainly by Hyalomma ticks in North Gujarat, India, which is important baseline data for future research and control strategies. This is the first report on Theileria and Anaplasma co-infections in sheep and goats from North Gujarat, India.

Abstract
AbstractThe risk of pathogen transmission continues to increase significantly in the presence of tick vectors due to the trade of livestock across countries. In Ghana, there is a lack of data on the incidence of tick-borne pathogens that are of zoonotic and veterinary importance. This study, therefore, aimed to determine the prevalence of such pathogens in livestock using molecular approaches. A total of 276 dry blood spots were collected from cattle (100), sheep (95) and goats (81) in the Kassena-Nankana Districts. The samples were analyzed using Polymerase Chain Reaction (qPCR) and conventional assays and Sanger sequencing that targeted pathogens including Rickettsia, Coxiella, Babesia, Theileria, Ehrlichia and Anaplasma. An overall prevalence of 36.96% was recorded from the livestock DBS, with mixed infections seen in 7.97% samples. Furthermore, the prevalence of infections in livestock was recorded to be 19.21% in sheep, 14.13% in cattle, and 3.62% in goats. The pathogens identified were Rickettsia spp. (3.26%), Babesia sp. Lintan (8.70%), Theileria orientalis (2.17%), Theileria parva (0.36%), Anaplasma capra (18.48%), Anaplasma phagocytophilum (1.81%), Anaplasma marginale (3.26%) and Anaplasma ovis (7.25%). This study reports the first molecular identification of the above-mentioned pathogens in livestock in Ghana and highlights the use of dry blood spots in resource-limited settings. In addition, this research provides an update on tick-borne pathogens in Ghana, suggesting risks to livestock production and human health. Further studies will be essential to establish the distribution and epidemiology of these pathogens in Ghana.

Abstract
The order Rickettsiales in the class Alphaproteobacteria comprises vector-borne pathogens of both medical and veterinary importance. Ticks, as a group, are second only to mosquitoes as vectors of pathogens to humans, playing a critical role in the transmission of rickettsiosis. In the present study, 880 ticks collected from Jinzhai County, Lu'an City, Anhui Province, China in 2021-2022 were identified as belonging to five species from three genera. DNA extracted from individual ticks was examined using nested polymerase chain reaction targeting the 16S rRNA gene (rrs), and the gene fragments amplified were sequenced to detect and identify Rickettsiales bacteria in the ticks. For further identification, the rrs-positive tick samples were further amplified by PCR targeting the gltA and groEL gene and sequenced. As a result, 13 Rickettsiales species belonging to the genera Rickettsia, Anaplasma, and Ehrlichia were detected, including three tentative species of Ehrlichia. Our results reveal the extensive diversity of Rickettsiales bacteria in ticks from Jinzhai County, Anhui Province. There, emerging rickettsial species may be pathogenic and cause under-recognized diseases. Detection of several pathogens in ticks that are closely related to human diseases may indicate a potential risk of infection in humans. Therefore, additional studies to assess the potential public health risks of the Rickettsiales pathogens identified in the present study are warranted.

Abstract
This study aimed to evaluate the frequency of IgG antibodies against A. marginale, the occurrence of this bacterium by qPCR, and the effect of bovine anaplasmosis as a risk factor for clinical cases of retained placenta, mastitis, and abomasal displacement in dairy cattle. For that 179 Holstein cows out of three dairy herds, in the municipality of Sertão, Rio Grande do Sul, Brazil. These cows were on farms that were vulnerable to risk factors that are crucial to susceptibility among these animals to this intracellular hemoparasite. The mean seropositivity for A. marginale from the periods evaluated was 54% on farm A, 69.4% on farm B, and 27.3% on farm C. Molecular diagnosis was performed with qPCR and the mean positivity for A. marginale among the cows on farms A, B, and C in December 2017 was 34.6% (67/179). Infected animals showed clinical cases of retained placenta (6.1%), mastitis (6.1%), and abomasal displacement (0.5%). The association between positivity for anaplasmosis and these clinical cases was assessed through the odds ratio. Our results show that females with a positive qPCR assay for A. marginale had 52.48 times increased probability (OR) to develop clinical cases of retained placenta and mastitis (P < 0.001). These clinical cases negatively impact the productivity of positive females. Thus, implementing preventive and prophylactic control measures to ensure the sanitary quality of the herds is needed to avoid losses due to morbidity and mortality and diminish the economic losses suffered by farmers.

Abstract
Anaplasma marginale is an obligate intracellular Gram-negative bacterium that is parasitic to erythrocytes and is the main agent of bovine anaplasmosis. This disease causes severe anemia and reduces weight gain and milk production, thus giving rise to major economic losses relating to livestock worldwide. The genetic diversity of this bacterium has been characterized based on sequences of major surface proteins (MSPs), especially MSP1α. This has enabled identification of several geographical strains, according to different amino acid sequences. The aim of this study was to investigate the genetic diversity of A. marginale in naturally infected Angus beef cattle during a disease outbreak in southeastern Brazil. Four blood samples were collected over a four-month period from each of 20 animals on a cattle farm in Itú, São Paulo, Brazil. Serum samples were subjected to indirect ELISA to detect anti-A. marginale IgG antibodies. The 80 whole-blood samples obtained were subjected to DNA extraction, quantitative real-time PCR (qPCR) for the msp1β gene, semi-nested PCR (snPCR) for the msp1α gene, cloning of the target fragment and sequencing using the Sanger method. The sequences obtained were analyzed for genetic diversity using the RepeatAnalyzer software. Both iELISA tests, using recombinant MSP5 and the Anaplasma antibody test kit (VMRD), revealed high seroprevalence: 91.25% and 97.5%, respectively. In qPCR, 100% of the samples were positive, with between 103 and 107 DNA copies/μL. In the snPCR based on the msp1α gene, 57.5% (46/80) of the samples were positive. Microsatellite analysis on the 36 sequences obtained showed the presence of genotypes H (58.3%), F (25%), E (19.4%), C (2.7%) and G (2.7%). The RepeatAnalyzer software identified 36 strains in the study region, among which some had not previously been described in the literature (13 27 13 27 13 F; 16 FF; τ 27; 63 29 104 29; LJ1 13 LJ1 13; 16 F 17; 16 F 91). High genetic diversity of A. marginale bacteria was found on this farm in Itú, São Paulo.

Recombinase polymerase amplification (RPA) with lateral flow detection for three Anaplasma species of importance to livestock health. Sci Rep 2021; 11:15962. [PMID: 34354122 PMCID: PMC8342517 DOI: 10.1038/s41598-021-95402-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 07/22/2021] [Indexed: 02/07/2023] Open
Abstract
Anaplasma marginale, A. ovis, and A. phagocytophilum are the causative agents of bovine anaplasmosis, ovine anaplasmosis, and granulocytic anaplasmosis, respectively. The gold standard for diagnosis of post-acute and long-term persistent infections is the serological cELISA, which does not discriminate between Anaplasma species and requires highly equipped laboratories and trained personnel. This study addresses the development of a rapid, isothermal, sensitive, species-specific RPA assays to detect three Anaplasma species in blood and cELISA A. marginale-positive serum samples. Three RPA primer and probe sets were designed targeting msp4 genes of each Anaplasma species and the internal control (GAPDH gene) for each assay. The limit of detection of gel-based or RPA-basic assays is 8.99 × 104 copies/µl = A. marginale, 5.04 × 106 copies/µl = A. ovis, and 4.58 × 103 copies/µl = A. phagocytophilum, and for each multiplex lateral flow or RPA-nfo assays is 8.99 × 103 copies/µl of A. marginale, 5.04 × 103 copies/µl of A. ovis, 4.58 × 103 copies/µl of A. phagocytophilum, and 5.51 × 103 copies/µl of internal control (GAPDH). Although none of the 80 blood samples collected from Oklahoma cattle were positive, the RPA-nfo assays detected all A. marginale cattle blood samples with varying prevalence rates of infection, 83% of the 24 cELISA A. marginale-positive serum samples, and all A. phagocytophilum cell culture samples. Overall, although early detection of three Anaplasma species was not specifically addressed, the described RPA technique represents an improvement for detection of three Anaplasma in regions where access to laboratory equipment is limited.

Molecular detection and phylogenetic analyses of Anaplasma spp. in Haemaphysalis longicornis from goats in four provinces of China. Sci Rep 2021; 11:14155. [PMID: 34238975 PMCID: PMC8266805 DOI: 10.1038/s41598-021-93629-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 06/28/2021] [Indexed: 01/05/2023] Open
Abstract
Anaplasma species, which are distributed worldwide, are gram-negative obligate intracellular tick-borne bacteria that pose a threat to human and animal health. Haemaphysalis longicornis ticks play a vital role as vectors in the transmission of Anaplasma pathogens. However, the Anaplasma species carried by H. longicornis in China are yet to be characterized. In this study, 1074 H. longicornis specimens were collected from goats in four provinces of China from 2018 to 2019 and divided into 371 sample pools. All tick sample pools were examined for the presence of Anaplasma species via nested PCR amplification of 16S ribosomal RNA, major surface protein 4 (msp4), or citric acid synthase (gltA) genes, which were sequenced to determine the molecular and phylogenetic characteristics of the isolates. The overall Anaplasma spp-positive rate of H. longicornis was determined to be 26.68% (99/371). The percentage prevalence of A. phagocytophilum-like1, A. bovis, A. ovis, A. marginale, and A. capra were 1.08% (4/371), 13.21% (49/371), 13.21% (49/371), 1.35% (5/371), and 10.24% (38/371), respectively, and the co-infection rate of two or more types of Anaplasma was 6.47% (24/371). Phylogenetic analyses led to the classification of A. phagocytophilum into an A. phagocytophilum-like1 (Anaplasma sp. Japan) group. Anaplasma bovis sequences obtained in this study were 99.8–100% identical to those of an earlier strain isolated from a Chinese tick (GenBank accession no. KP314251). Anaplasma ovis sequences showed 99.3–99.6% identity to an A. ovis human strain identified from a Cypriot patient (GenBank accession no. FJ460443). Only one msp4 sequence of A. marginale was detected and was grouped with those of other A. marginale isolates, and these A. capra isolates obtained in this present study may be zoonotic. The detection and characterization of four Anaplasma species in H. longicornis in this study have added to the current knowledge of the parasite and provided data on multiple Anaplasma species with veterinary and medical significance from four provinces of China.
