Torres-Santos PT, Evaristo AMDCF, Santos JR, Collere FCM, Vieira TSWJ, Pereira LCM, Nicola PA, Vieira RFDC, Horta MC. Hemoplasmas in wild rodents and marsupials from the Caatinga Biome, Brazil. Acta Trop 2024; 258:107334. [PMID: 39127138 DOI: 10.1016/j.actatropica.2024.107334] [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: 04/02/2024] [Revised: 07/15/2024] [Accepted: 07/24/2024] [Indexed: 08/12/2024]
Abstract
A total of 231 blood samples from wild mammals belonging to the orders Rodentia (n = 142) and Didelphimorphia (n = 89) were screened by real-time PCR assay (qPCR), being six Rhipidomys sp., 118 Thrichomys laurentius, nine Rattus rattus, four Kerodon rupestris, five Necromys lasiurus, 42 Didelphis albiventris and 47 Monodelphis domestica. Results using qPCR showed that 32 of the total 231 (13.85 %) samples were positive for hemoplasma sequences of the 16S rRNA gene. Sequences from two D. albiventris showed 99.77-99.89 % identity with 'Candidatus Mycoplasma haemoalbiventris' and 99.09 % with 'Candidatus Mycoplasma haemodidelphidis', respectively. Furthermore, one M. domestica and five T. laurentius showed 99.72-99.77 % identity with Mycoplasma sp., and one K. rupestris showed 98.13 % identity with 'Candidatus Mycoplasma haematohydrochaerus'; and from two Rattus rattus showed 99.65-99.89 % identity with Mycoplasma sp. and 'Candidatus Mycoplasma haemomuris'. The 23S rRNA gene sequences obtained from the two D. albiventris showed 100 % identity with 'Ca. M. haemoalbiventris' whereas the sequences from the R. rattus showed only 85.31 % identity with 'Candidatus Mycoplasma haematohydrochaerus'. Two T. laurentius and one K. rupestris showed 84.66-92.97 % identity with 'Candidatus Mycoplasma haemosphiggurus'. Based on phylogenetic and Neighbor-Net network analyses of the 16S and 23S rRNA genes, potential novel species are described. In addition, 'Ca. M. haemoalbiventris' was detected in Didelphis albiventris, and Mycoplasma sp. was detected in Rattus sp. rodents from the Caatinga biome, Brazil.

Abstract
Hemotropic mycoplasmas are bacteria that attaches to erythrocytes surface, which some species presents zoonotic concerns. In the suborder Pinnipedia, genera Otaria and Arctocephalus are prominent in Brazil. This study investigated the occurrence of hemoplasmas in Arctocephalus sp. and Otaria flavescens found dead along the coast of a Southern Brazilian State. DNA from 135 spleen samples were extracted and subjected to conventional PCR protocols, targeting the 16 S rRNA and 23 S rRNA gene. Three (2.22 %) Arctocephalus australis were positive in the 16 S rRNA gene, and no samples amplified in the 23 S rRNA gene. Samples from this study clustered with Zalophus californianus and Arctocephalus tropicalis mycoplasmas on a Bayesian phylogenetic analysis. Genetic diversity analysis suggested distinct genotypes, indicating A. australis as a new host for hemoplasma, and also a potential putative novel hemoplasma genotype. These findings raises future awareness for pinnipeds conservation, and adds Mycoplasma spp. to be taken into consideration when clinically evaluating rescued animals.

Abstract
Hemotropic mycoplasmas (hemoplasmas) are emerging zoonotic pathogens. Micromammals have received little attention as hosts for hemoplasmas despite their ubiquitous presence, high population abundances, and close association with humans. A PCR protocol targeting a fragment of the 16 S rRNA gene and direct sequencing in blood samples of 189 adult specimens and 35 fetuses belonging to three species of Eulipotyphla (shrews) and seven species of Rodentia, captured in three ecologically diverse habitats in North-Eastern Spain (Steppe, High Mountain, Mediterranean) yielded and occurrence of 26%, including 36% of 39 shrews and 23% of 150 rodents. Sequencing revealed the presence of 14 nucleotide sequence types (ntST) among the 56 readable sequences. In general, each ntST was associated with a given host species, although in some cases, the same ntST was sequenced in different species (chiefly rodents). Most ntST were closely related to rodent and/or bat hemoplasmas, but one was identical with Mycoplasma haemocanis/haemofelis, and others can be considered novel genotypes. High sequence diversity was detected in rodents, whereas in the white-toothed shrew (Crocidura russula), 9/11 sequences from two distant areas were identical. Phylogenetic and network analyses classified our sequences in different clades including hemoplasmas of rodents, carnivores, bats, and humans. Twelve of the fetuses (34.2%) of 9/12 litters (75.0%) of shrews and rodents were hemoplasma-positive, indicating frequent vertical transmission. Our study contributes to expanding our knowledge about the distribution, diversity, and transmission of hemoplasmas.

Establishment of molecular diagnostics targeting the 23S ribosomal RNA gene for the detection of Mycoplasma suis infection in Thai domestic pigs. Acta Trop 2023; 238:106759. [PMID: 36403675 DOI: 10.1016/j.actatropica.2022.106759] [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: 09/13/2022] [Revised: 10/27/2022] [Accepted: 11/16/2022] [Indexed: 11/21/2022]
Abstract
Mycoplasma (M.) suis is a pathogenic hemotropic Mycoplasma sp. that causes acute hemolytic anemia or chronic infection in pigs. M. suis infection can be diagnosed using several methods, including molecular diagnosis such as conventional PCR (cPCR) and quantitative PCR (qPCR). In these cases, the common target is the 16S rRNA gene; however, this genetic marker cannot distinguish hemoplasma at the species level owing to high sequence identity. Therefore, the 23S rRNA gene has emerged as another target gene. Other than PCR, the loop-mediated isothermal amplification (LAMP) method can be applied for M. suis. The objective of the present study was to establish cPCR, TaqMan qPCR, and LAMP assays in which the 23S rRNA gene is used to detect M. suis infection in Thai domestic pigs. The analytical sensitivity of cPCR was determined as 7.46 × 104 copies/μl of plasmid DNA, whereas those of qPCR and LAMP were 7.46 × 102 copies/μl. There was no cross reaction with other pathogens in any of the assays. To evaluate the diagnostic performance of the assays, they were tested using 173 samples of genomic DNA. The detection percentage of M. suis infection was 24.86% (43/173; 95% CI: 18.61%-31.89%), 28.32% (49/173; 95% CI: 21.75%-35.66%), and 29.48% (51/173; 95% CI: 22.80%-36.88%) using cPCR, qPCR, and LAMP, respectively. Using qPCR as a reference assay, cPCR showed 81.63% sensitivity, 97.58% specificity, and an almost perfect level of agreement (kappa = 0.823). In comparison, LAMP showed 77.55% sensitivity, 89.52% specificity, and a substantial level of agreement (kappa = 0.662). All assays tested here could be applied in veterinary diagnostic laboratories for monitoring porcine health in the herds. Furthermore, the LAMP assay could be used as a screening test in farm practice without the need for any special equipment.

Expanding the Universe of Hemoplasmas: Multi-Locus Sequencing Reveals Putative Novel Hemoplasmas in Lowland Tapirs ( Tapirus terrestris), the Largest Land Mammals in Brazil. Microorganisms 2022; 10:614.

Abstract
The lowland tapir (Tapirus terrestris) is the largest land mammal in Brazil and classified as a vulnerable species, according to the assessment of the risk of extinction. The present study aimed at investigating the occurrence and genetic diversity of hemoplasmas in free-ranging T. terrestris from the Brazilian Pantanal and Cerrado biomes. Blood samples were collected from 94 living and eight road-killed tapirs, totalizing 125 samples Conventional PCR targeting four different genes (16S rRNA, 23S rRNA, RNAse P, and dnaK) were performed, and the obtained sequences were submitted for phylogenetic, genotype diversity, and distance analyses. The association between hemoplasma positivity and possible risk variables (age, gender, and origin) was assessed. Out of 122 analyzed samples, 41 (41/122; 33.61% CI: 25.84-42.38%) were positive in the 16S rRNA-based PCR assay for hemoplasmas. Positivity for hemoplasmas did not differ between tapirs' gender and age. Tapirs from Pantanal were 5.64 times more likely to present positive results for hemoplasmas when compared to tapirs sampled in Cerrado. BLASTn, phylogenetic, genotype diversity, and distance analyses performed herein showed that the sampled lowland tapirs might be infected by two genetically distinct hemoplasmas, namely 'Candidatus Mycoplasma haematoterrestris' and 'Candidatus Mycoplasma haematotapirus'. While the former was positioned into "Mycoplasma haemofelis group" and closely related to 'Candidatus Mycoplasma haematoparvum, the latter was positioned into "Mycoplasma suis group" and closely related to 'Candidatus Mycoplasma haematobos'. The impact of both putative novel species on tapir health status should be investigated.

Abstract
The Iguaçu National Park (INP) is the largest remnant of Atlantic Forest in southern Brazil, representing an ecological continuum with Argentina. The INP harbours a diverse fauna, with ring-tailed coatis (Nasua nasua Linnaeus, 1976, Carnivora: Procyonidae) in close contact with tourists either begging and/or snatching food from visitors. A potentially novel haemotropic Mycoplasma sp. has been previously detected in the ring-tailed coatis from central-western and southern Brazil. Therefore, the aims of this study were to investigate the occurrence of haemotropic Mycoplasma sp. and tick-borne pathogens in wild ring-tailed coatis from the INP, Foz do Iguaçu municipality, Paraná State, southern Brazil. Blood samples were collected from 18 wild ring-tailed coatis and evaluated by conventional PCR (cPCR) assays for haemotropic Mycoplasma spp. (16S and 23S rRNA), Theileria/Babesia spp. (18S rRNA) and Ehrlichia/Anaplasma spp. (16S rRNA, sodB, dsb and groEL). Eight out of 18 (44.44%; 95% CI: 24.56%-66.28%) animals were positive for haemotropic Mycoplasma spp. All ring-tailed coatis tested negative for Theileria/Babesia spp. and only one out of 18 (5.56%; 95% CI: 0.99%-25.76%) animals tested positive for Ehrlichia/Anaplasma spp. by the 16S rRNA cPCR. Unfortunately, multiple attempts to sequence the 16S rRNA gene of the Ehrlichia/Anaplasma-positive sample have failed. Phylogenetic and network analysis of the hemoplasma 16S and 23S rRNA gene fragments confirmed that animals were infected by a potentially novel haemotropic Mycoplasma sp. previously reported in ring-tailed coatis from Brazil. The name 'Candidatus Mycoplasma haematonasua' is proposed for this novel organism.

Transbound Emerg Dis 2020; 68:3236-3256. [PMID: 33210822 DOI: 10.1111/tbed.13932] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 11/13/2020] [Accepted: 11/14/2020] [Indexed: 12/17/2022]
Abstract
Haemotropic mycoplasmas (haemoplasmas) have increasingly attracted the attention of wildlife disease researchers due to a combination of wide host range, high prevalence and genetic diversity. A systematic review identified 75 articles that investigated haemoplasma infection in wildlife by molecular methods (chiefly targeting partial 16S rRNA gene sequences), which included 131 host genera across six orders. Studies were less common in the Eastern Hemisphere (especially Africa and Asia) and more frequent in the Artiodactyla and Carnivora. Meta-analysis showed that infection prevalence did not vary by geographic region nor host order, but wild hosts showed significantly higher prevalence than captive hosts. Using a taxonomically flexible machine learning algorithm, we also found vampire bats and cervids to have greater prevalence, whereas mink, a subclade of vesper bats, and true foxes all had lower prevalence compared to the remaining sampled mammal phylogeny. Haemoplasma genotype and nucleotide diversity varied little among wild mammals but were marginally lower in primates and bats. Coinfection with more than one haemoplasma species or genotype was always confirmed when assessed. Risk factors of infection identified were sociality, age, males and high trophic levels, and both prevalence and diversity were often higher in undisturbed environments. Haemoplasmas likely use different and concurrent transmission routes and typically display enzootic dynamics when wild populations are studied longitudinally. Haemoplasma pathology is poorly known in wildlife but appears subclinical. Candidatus Mycoplasma haematohominis, which causes disease in humans, probably has it natural host in bats. Haemoplasmas can serve as a model system in ecological and evolutionary studies, and future research on these pathogens in wildlife must focus on increasing the geographic range and taxa of studies and elucidating pathology, transmission and zoonotic potential. To facilitate such work, we recommend using universal PCR primers or NGS protocols to detect novel haemoplasmas and other genetic markers to differentiate among species and infer cross-species transmission.
