First detection and molecular characterization of Mycoplasma species in camels, cattle, buffalo, and their associated ticks from southern Egypt. INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2025; 130:105750. [PMID: 40210105 DOI: 10.1016/j.meegid.2025.105750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2025] [Revised: 04/06/2025] [Accepted: 04/07/2025] [Indexed: 04/12/2025]
Abstract
Mycoplasma species are wall-less bacteria that infect multiple mammalian orders, including livestock, and are associated with economically significant diseases. In Egypt, molecular data on the presence and diversity of Mycoplasma spp. in camels, cattle, buffalo, and their associated ticks remain limited, despite their potential impact on livestock health and productivity. This study aimed to detect and genetically characterize Mycoplasma spp. in cattle, buffalo, camels, and their associated ticks in southern Egypt. A total of 571 samples (384 ticks, 50 buffalo, 68 cattle, and 69 camels) were screened using PCR targeting the 16S rRNA gene, followed by phylogenetic analysis of representative amplicons. Hyalomma dromedarii, Hyalomma marginatum, and Rhipicephalus annulatus were the tick species collected. Overall, Mycoplasma DNA was detected in 10.3 % of the samples. Mycoplasma ovis-like was identified in 2.9 % of camel blood, 9.4 % of H. dromedarii, 75 % of H. marginatum, and 13.8 % of R. annulatus ticks. Candidatus Mycoplasma haematovis was found in 0.4 % of H. dromedarii, and Mycoplasma wenyonii-like in 13.2 % of cattle and 4 % of buffalo blood. Remarkably, this is the first global detection of M. ovis in camel blood, as well as the detection of M. ovis-like and Ca. M. haematovis in ticks circulating on camels. This study also reports the first detection of M. wenyonii-like in bovines in Egypt and documents M. ovis-like in three tick species parasitizing cattle. The genetic similarities of Mycoplasma sequences from ticks and livestock suggest that these arthropods may serve as potential vectors. These findings highlight the need for additional studies on the zoonotic potential, infectivity, and vector competence of Mycoplasma spp. in Egypt.

[PMID: 38395406 DOI: 10.3168/jds.2023-24395] [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: 11/03/2023] [Accepted: 01/23/2024] [Indexed: 02/25/2024]
Abstract
The bovine hemoplasmas include Mycoplasma wenyonii and Candidatus Mycoplasma haemobos, which are increasingly recognized as infecting cattle throughout the world. Infection with hemotropic mycoplasma has been reported to be widespread in mature dairy cows, but little is known about its prevalence in calves and heifers. The objective of this study was to investigate the prevalence and dynamics of infection with M. wenyonii and C. M. haemobos in calves and replacement heifers on Michigan dairy farms and assess the potential associations between infection status and hematological values. The study was designed as a prospective cross-sectional study with a longitudinal component. A convenience sample of 11 farms agreed to participate and were visited twice between March and September 2022. During the first farm visit, researchers collected blood samples from up to 94 animals per farm distributed among newborn and preweaning calves (n ≤ 31), weaned calves (n = 21), pre-breeding heifers (n = 21), and pregnant heifers (n = 21). During the first visit, blood samples (n = 174) were also collected from a convenience sample of mature cows to confirm the herd infection status. The same calves and heifers were sampled again ∼95 d (±3.0) later. During the first visit, blood samples were collected from 797 calves and replacement heifers, whereas 675 samples were collected during the second visit due to the inability to locate some animals. Detection of M. wenyonii and C. M. haemobos was based on results of real-time PCR. The hematocrit was determined using microcentrifugation, and the concentration of leukocytes using an automated cell counter. In all herds, most mature cows that were sampled tested positive for infection. The within-herd apparent prevalence of hemoplasma in calves and replacement heifers was 100% for both M. wenyonii and C. M. haemobos. The apparent prevalence of hemoplasma in youngstock was associated with age. In calves that were 1 to 6 mo old, the prevalence of infection was 6% to 8% but sharply increased to 31% by 8 mo of age. In older animals, the prevalence remained high, and was almost 100% in animals greater than 17 mo of age. Based on calves and heifers sampled twice, the cumulative incidence varied widely among herds, ranging from 3.7% to 96.0%, and increased with the age of the animals. We found no difference in hematocrit or number of lymphocytes, monocytes, neutrophils, or total leukocytes based on infection status. The number of eosinophils was greater in infected animals. This is the first study to report the prevalence of hemoplasmas in calves and replacement heifers in the United States. It indicates that young calves can be infected with hemoplasmas, but the rate of infection is low. The likelihood of infection increases as animals age, with a notable rise in the proportion of infected heifers occurring by 8 mo old, and the prevalence eventually reaching nearly 100% in older animals. Once infected, heifers appear to remain chronic carriers. Hemoplasma infection alone does not usually lead to the development of clinical signs, and most of the animals remain apparently healthy.

Abstract
The objective of this narrative literature review is to better understand bovine hemoplasmosis, an emerging disease that threatens dairy animal health. Several species of hemotropic mycoplasma are known to infect both animals and humans, and Mycoplasma wenyonii and Candidatus Mycoplasma haemobos are the species that infect red blood cells of cattle. These microorganisms are associated with clinical signs in dairy cattle, but the effects of infection on health and productivity of dairy cows are poorly understood. In this paper, we review information about the epidemiology of bovine hemoplasmosis in different countries, including clinical signs associated with hemoplasmosis in cattle, methods of diagnosis, treatment, possible routes of transmission, risk factors for infection, and disease progression. Although hemoplasmas have been reported to infect cattle in many countries, and methods used to detect these organisms have improved, numerous gaps in knowledge were identified. The pathogenesis of the disease and potential effect on animal health and productivity remain unclear. With this review, we seek to contribute to the understanding of hemoplasmosis in cattle and provide insights for further research to improve disease management strategies and overall animal health in the dairy industry.

Abstract
BACKGROUND Hemotropic mycoplasmas or hemoplasmas are bacteria that attach to the erythrocyte surface and cause bovine hemoplasmosis. Two species, Mycoplasma wenyonii and Candidatus Mycoplasma haemobos, have been identified and shown to be distributed worldwide. However, there is currently no information available on hemoplasmas in cattle in the Republic of Korea. The aim of this study was to investigate the presence of hemoplasmas in Korean native cattle and to evaluate the association between hemoplasma infection and anemia. METHODS One farm was selected, at which blood samples were collected from 104 Korean native cattle [grazing cattle (n = 89) and housed cattle (n = 15)]. Hemoplasmas were detected via polymerase chain reaction analysis and complete blood counts were also performed. RESULTS The overall prevalence of hemoplasmas was 34% (35/104); 20.2% (21/104) for M. wenyonii, 3.8% (4/104) for C. M. haemobos, and 9.6% (10/104) for co-infection. Candidatus Mycoplasma haemobos was detected only in grazing cattle. Of red blood cell (RBC) parameters, C. M. haemobos-infected cattle had lower RBC and hematocrit, and higher mean cell volume than hemoplasma-negative cattle, although none of these differences were statistically significant. This is the first study to report the occurrence of M. wenyonii and C. M. haemobos. Mycoplasma wenyonii is more prevalent than C. M. haemobos in Korean native cattle. The results did not show an association between hemoplasma infection and anemia. CONCLUSIONS Considering the infection rate of hemoplasmas shown in this study, further studies, such as on the pathogenicity and clinical significance of hemoplasmas are necessary.

Acta Parasitol 2023:10.1007/s11686-023-00683-0. [PMID: 37170044 DOI: 10.1007/s11686-023-00683-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 04/24/2023] [Indexed: 05/13/2023]
Abstract
PURPOSE The extensive migration practiced by pastoralists cattle exposes them to a variety of pathogens and vectors which may sometimes lead to severe disease outcomes. Moreover, the synergistic effect of multiple parasitism on the productivity of livestock has been well recognized. This is particularly true where the livestock production system predisposes the animals to constant and heavy infestation with arthropod vectors. METHODS The presences, prevalence and risk factors for hemotropic Mycoplasma (hemoplasma) infection in cattle in Nigeria was investigated using a PCR and sequencing approach. DNA, extracted from 566 cattle blood samples, collected from 10 states from the three agro-ecological zones (AEZs) of Nigeria, from April 2021 to March 2022, were screened for the presences of hemotropic Mycoplasma spp. DNA. RESULTS The DNA of hemoplasmas was detected in 48 out of the 566 (8.5%) samples, 12 (25%) of them were identified as Mycoplasma wenyonii and 19 (38.6%) as 'Candidatus Mycoplasma haemobos'. Coinfection with both species was detected in 17 (35.4%) of the samples. High prevalence and risk of hemoplasmas infection was associated with sex of the cattle (bulls were more affected; p = 0.005) and the packed cell volume (p = 0.009), but not with the age (p = 0.08), breed (p = 0.22), body condition (p = 0.052), source of the samples (p = 0.45) or the AEZs (0.59). This is the first nationwide survey of hemotropic mycoplasmas in cattle in Nigeria using this molecular approach. CONCLUSION Further studies to determine the veterinary and public health significance of these pathogens, which were previously associated with varying degrees of clinical signs and production losses, are recommended in Nigerian cattle.

Abstract
New emerging diseases, including 'Candidatus Mycoplasma haemobos' ('Ca. M. haemobos') and HoBi-like pestivirus in central China has been a huge challenge for ruminant production. From July to September 2022, an abortion outbreak affected 14 goat farms and 11 cattle farms in this area. To investigate whether the two pathogens are associated with the disease, samples were collected: Group 1 included 55 goat blood samples with foetal tissue samples and ticks on the skin; Group 2 included nine healthy goat blood samples; Group 3 included 36 cow blood samples with foetal tissue samples and ticks on the skin; and Group 4 included seven healthy cow blood samples. Then, these samples were analysed by serology, PCR, sequence analysis, and identification. A total of 339 Rhipicephalus (Boophilus) microplus and 61 Haemaphysalis longicornis ticks were identified in Group 1 and Group 3. By molecular detection, 32 'Ca. M. haemobos'-positive amplicons, and 27 HoBi-like pestivirus-positive amplicons were amplified from goats in Group 1; meanwhile, 20 'Ca. M. haemobos'-positive amplicons, and 18 HoBi-like pestivirus-positive amplicons were amplified from foetuses. Statistical significance (P = 0.002) and association (OR=7.556) between the 'Ca. M. haemobos' PCR results of foetus and goat samples were observed, and statistical significance (P = 0.017) and association (OR=4.271) between the HoBi-like pestivirus PCR results of foetus and goat samples were observed. These significances and associations were also observed in Group 3. In addition, coinfections were detected in Group 1 and Group 3. 'Ca. M. haemobos' was detected in both tick species. Further serological results revealed that the frequency of HoBi-like pestivirus was 20.0 % (11/55) in Group 1 % and 30.6 % (11/36) in Group 3 in central China. No ticks, pathogens, or neutralizing antibodies were observed in Group 2 or Group 4. This is the first molecular evidence of 'Ca. M. haemobos' and HoBi-like pestivirus natural coinfections in goats and cows with abortion in China. HoBi-like pestivirus and 'Ca. M. haemobos' can be transferred from goats/cows to their foetuses.

Abstract
Hemoplasma species can cause infection varying from mild to severe in a wide range of hosts, including cattle and water buffalo. Two hemoplasma species, Mycoplasma wenyonii and Candidatus Mycoplasma haemobos, have been reported in cattle and water buffalo from different parts of the world to date. There was a lack of information on the presence and distribution of these pathogens in Turkey despite the negative economic impact on livestock production. This study aimed to develop a duplex PCR assay amplifying the 16S rRNA gene, in order to analyze DNA samples obtained from 297 cattle and 360 water buffaloes, and to determine the molecular prevalence of bovine hemoplasma species in Sivas province. Bovine hemoplasma species were found in 94 of 297 (31.64%) cattle and in 17 of 360 (4.72%) water buffaloes in this study. Randomly selected six positives PCR products (three samples each species) obtained from cattle and water buffaloes were sequenced, and the consensus sequences were uploaded to GenBank. Nucleotide similarity of 96.97-100% was determined between M. wenyonii isolates obtained in this study and those of M. wenyonii isolates present in the GenBank database, whereas C. Mycoplasma haemobos isolates from this study shared 99.04-100% homology with the C. Mycoplasma haemobos isolates uploaded to the GenBank. With the current study, the molecular presence of M. wenyonii and C. Mycoplasma haemobos were documented for the first time in cattle and water buffaloes in Turkey. Considering the rate of prevalence, veterinarians should take precautions against bovine hemoplasma species to protect animal health.

Abstract
Mycoplasma wenyonii and 'Candidatus Mycoplasma haemobos' are bacteria that have been described as significant hemoplasmas that infect cattle worldwide. Currently, three bovine hemoplasma genomes are known. This work aimed to describe the main genomic characteristics and the evolutionary relationships between hemoplasmas, and provide a list of epitopes predicted by immunoinformatics as diagnostic candidates for bovine hemoplasmosis. Thus far, there is no vaccine to prevent this disease that economically impacts cattle production worldwide. Additionally, there is a lack of vaccines against bovine hemoplasmosis. In this work, we performed a genomic characterization of hemoplasmas, including two Mexican strains reported in bovines in the last few years. The generated information is a new scenario about the phylogeny of hemoplasmas. Also, we show genomic features among hemoplasmas that strengthen their characteristic genome plasticity of intracellular lifestyles. Finally, the elucidation of antigenic proteins in Mexican strains represents an opportunity to develop molecular detection methods and diagnoses.
