Abstract
The genetic structure and evolutionary relationship of Dulong chicken with other native Chinese species remained unclear. In this study, the mitochondrial control region was analyzed in total of 343 samples comprising 59 from Dulong chicken and 284 from 8 other Chinese local breeds revealed 51 mutation sites that defined 42 haplotypes. The maximum genetic variation was observed between the Shimian caoke and Pengxian yellow chickens. Phylogenetic analysis revealed that these local chickens mainly scatter in two southwestern clades. Dulong chickens have close relationship with other native chicken. Finding of this study suggests a single matrilineal lineage of indigenous Dulong chickens.

Phenotypic Characterization of Chinese Rhesus Macaque Plasmablasts for Cloning Antigen-Specific Monoclonal Antibodies. Front Immunol 2019; 10:2426. [PMID: 31681312 PMCID: PMC6798180 DOI: 10.3389/fimmu.2019.02426] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Accepted: 09/27/2019] [Indexed: 11/14/2022] Open
Abstract
Rhesus macaques (Macaca mulatta) are used as a human-relevant animal species for the evaluation of vaccines and as a source for cloning monoclonal antibodies (mAbs) that are highly similar to human-derived antibodies. Although antibody-secreting plasmablasts in humans are well-defined and can be easily isolated for mAb cloning, it remains unclear whether the same phenotypic markers could be applied for isolating antibody-secreting plasmablasts from Chinese rhesus macaques. In this study, we evaluated a series of cell surface and intracellular markers and identified the phenotypic markers of plasmablasts in Chinese rhesus macaques as CD3−CD14−CD56−CD19−CD27−CD20−/lowCD80+HLA-DR+CD95+. After influenza virus vaccination, the plasmablasts in peripheral blood mononuclear cells (PBMCs) increased transiently, peaked at day 4–7 after booster vaccination and returned to nearly undetectable levels by day 14. Antigen-specific enzyme-linked immunosorbent spot (ELISPOT) assays confirmed that the majority of the plasmablasts could produce influenza virus-specific antibodies. These plasmablasts showed transcriptional characteristics similar to those of human plasmablasts. Using single-cell PCR for immunoglobulin heavy and light chains, most mAbs cloned from the CD3−CD14−CD56−CD19−CD27−CD20−/lowCD80+HLA-DR+CD95+ plasmablasts after vaccination exhibited specific binding to influenza virus. This study defined the phenotypic markers for isolating antibody-secreting plasmablasts from Chinese rhesus macaques, which has implications for efficient cloning of mAbs and for the evaluation of plasmablast response after vaccination or infection in Chinese rhesus macaques.

Abstract
Rhesus macaques are raised in almost every Chinese zoo due to their likeability and ease in feeding; however, little is yet known about the genetic diversity of rhesus macaques in captivity. In this study, a 475-base pair nucleotide sequence of the mitochondrial DNA control region was obtained from the fecal DNA of 210 rhesus macaque individuals in captivity. A total of 69 haplotypes were defined, 51 of which (73.9%) were newly identified. Of all haplotypes, seven were shared between two zoos, and 62 haplotypes (89.8%) appeared only in a specific zoo, indicating a low rate of animal exchange between Chinese zoos. Moreover, there was a relatively high level of genetic diversity among the rhesus macaques (Hd = 0.0623 ± 0.0009, Pi = 0.979 ± 0.003, K = 28.974). Phylogenetic analysis demonstrated that all haplotypes were clearly clustered into two major haplogroups-Clade A (southeastern China) and Clade B (southwestern China)-and each major clade contained several small sub-haplogroups. The haplotypes of rhesus macaques from the same zoo were not clustered together for the most part, but scattered among several subclades on the phylogenetic tree. This indicates that the rhesus macaques in most Chinese zoos may originat from a diverse collection of geographical areas. Our results demonstrate that zoos play an important role in the conservation of the genetic diversity of rhesus macaques, as well as provide useful information on the genetic management of captive rhesus macaques.

Abstract
BACKGROUND Entamoeba spp. is one of the most common enteric parasites of humans and animals. PURPOSE However, little information is available regarding prevalence and genotypes of Entamoeba spp. in wild Taihangshan macaques (Macaca mulatta tcheliensis). METHODS In the present study, a total of 458 fecal samples from wild rhesus macaque in Taihangshan mountains area between September 2015 and November 2016, were collected and examined for the presence of six Entamoeba species by PCR amplification of the SSU rRNA gene. RESULTS The overall prevalence of Entamoeba spp. infection was 89.96% (412/458). Four species of Entamoeba detected in our survey were E. chattoni (88.43%), E. hartmanni (79.91%), E. coil (69.87%) and E. dispar (58.30%), and among these, 398 (84.93%) were mixed infections. Phylogenetic analysis revealed that isolates were clustered into four known genotypes. CONCLUSION The present study firstly provides important information about the prevalence and diversity of Entamoeba species infecting wild Taihangshan macaques in China. Enough attention should be paid to monitor the potential interspecies transmission in the region.

Abstract
BACKGROUND The genetic composition of cynomolgus macaques used in biomedical research is not as well-characterized as that of rhesus macaques. METHODS Populations of cynomolgus macaques from Sumatra, Corregidor, Mauritius, Singapore, Cambodia, and Zamboanga were analyzed using 24 STRs. RESULTS The Sumatran and Cambodian populations exhibited the highest allelic diversity, while the Mauritian population exhibited the lowest. Sumatran cynomolgus macaques were the most genetically similar to all others, consistent with an Indonesian origin of the species. The high diversity among Cambodian animals may result from interbreeding with rhesus macaques. The Philippine and Mauritian samples were the most divergent from other populations, the former due to separation from the Sunda Shelf by deepwater and the latter due to anthropogenic translocation and extreme founder effects. CONCLUSIONS Investigators should verify their research subjects' origin, ancestry, and pedigree to minimize risks to biomedical experimentation from genetic variance stemming from close kinship and mixed ancestry as these can obscure treatment effects.

Abstract
BACKGROUND Pliocene uplifting of the Qinghai-Tibetan Plateau (QTP) and Quaternary glaciation may have impacted the Asian biota more than any other events. Little is documented with respect to how the geological and climatological events influenced speciation as well as spatial and genetic structuring, especially in vertebrate endotherms. Macaca mulatta is the most widely distributed non-human primate. It may be the most suitable model to test hypotheses regarding the genetic consequences of orogenesis on an endotherm. METHODOLOGY AND PRINCIPAL FINDINGS Using a large dataset of maternally inherited mitochondrial DNA gene sequences and nuclear microsatellite DNA data, we discovered two maternal super-haplogroups exist, one in western China and the other in eastern China. M. mulatta formed around 2.31 Ma (1.51-3.15, 95%), and divergence of the two major matrilines was estimated at 1.15 Ma (0.78-1.55, 95%). The western super-haplogroup exhibits significant geographic structure. In contrast, the eastern super-haplogroup has far greater haplotypic variability with little structure based on analyses of six variable microsatellite loci using Structure and Geneland. Analysis using Migrate detected greater gene flow from WEST to EAST than vice versa. We did not detect signals of bottlenecking in most populations. CONCLUSIONS Analyses of the nuclear and mitochondrial datasets obtained large differences in genetic patterns for M. mulatta. The difference likely reflects inheritance mechanisms of the maternally inherited mtDNA genome versus nuclear biparentally inherited STRs and male-mediated gene flow. Dramatic environmental changes may be responsible for shaping the matrilineal history of macaques. The timing of events, the formation of M. mulatta, and the divergence of the super-haplogroups, corresponds to both the uplifting of the QTP and Quaternary climatic oscillations. Orogenesis likely drove divergence of western populations in China, and Pleistocene glaciations are likely responsible for genetic structuring in the eastern super-haplogroup via geographic isolation and secondary contact.

Abstract
Because wild rhesus macaque (Macaca mulatta) populations have suffered major declines, there is a growing need to characterize their genetic and population structure in order to protect the genetic integrity of this species. In this study, we genotyped a sample comprising 120 wild rhesus macaques from six sites in Sichuan Province for 30 nuclear microsatellite (STR) loci using an ABI 3130xl genetic analyzer. Bayesian analyses and PCA clearly differentiated monkeys from Heishui from those at other sites. The samples from all six sites exhibited high gene diversity suggesting that the Sichuan wild rhesus macaque populations are not threatened by a lack of genetic diversity. Deviation from Hardy-Weinberg equilibrium was more frequent in the Danba and Heishui populations. This may be due to the more fragmented habitat and less disturbance by humans in this area that foster greater subpopulation structuring than occurs in eastern China. We suggest that this population subdivision is the result of both long-term geographic barriers and human activity.

Abstract
Tibetan macaque (Macaca thibetana) is a threatened primate species endemic to China. Population genetic and phylogenetic analyses were conducted in 66 Tibetan individuals from Sichuan (SC), Huangshan (HS), and Fujian (FJ) based on a 477-bp fragment of mitochondrial DNA control region. Four new haplotypes were defined, and a relatively high level of genetic diversity was first observed in FJ populations (Hd = 0.7661). Notably, a continuous approximately 10 bp-fragment deletion was observed near the 5' end of the mtDNA control region of both HS and FJ populations when compared with that of SC population, and a sharing haplotype was found between the two populations, revealing a closer genetic relationship. However, significant genetic differentiation (FST = 0.8700) and more poor gene exchange (Nm < 1) had occurred among three populations. This study mainly provide a further insight into the genetic relationship between HS and FJ Tibetan macaque populations, but it may be necessary to carry out further study with extra samples from other locations in the geographic coverage of the two subspecies (M. thibetana pullus and M. thibetana huangshanensis).

Abstract
BACKGROUND While rates of gene flow between rhesus and longtail macaque populations near their hybrid zone in Indochina have been quantified elsewhere, this study demonstrates that the inter-specific introgression is not limited to the Indochinese hybrid zone but is more geographically widespread. METHODS Twelve rhesus and longtail macaque populations were analyzed using single nucleotide polymorphic (SNP) loci. RESULTS There is evidence for inter-specific admixture between Chinese rhesus and mainland longtails, with implications for genetic diversity both in the Chinese super-SPF population at the California National Primate Research Center and in other primate facilities. Eastern Chinese rhesus appeared more highly derived than western Chinese rhesus, and allele sharing between longtails and Chinese rhesus was not random with regard to geographic distance, but no significant nuclear genetic differences between eastern and western Chinese rhesus were detected among the 245 genic SNPs assayed. CONCLUSION The implications of this inter-specific admixture for the use of Chinese rhesus and mainland longtail in biomedical research should be considered.
