Complete Mitochondrial Genome of Trichuristrichiura from Macaca sylvanus and Papio papio.

ABSTRACT: Trichuriasis is among the most prevalent worldwide parasitism caused by helminths. For many years, Trichuris spp. have been described with a relatively narrow range of both morphological and biometrical features. The use of the complete mitochondrial genome (mitogenome) is an alternative and powerful molecular method for inferring phylogenies. Here, we present an overview of the contributions of mitogenome for Trichuris spp. from human and non-human primates. In addition, we carry out structural and phylogenetic comparative analyses with genomes of Trichuris species available in public datasets. The complete mt genomes of Trichuris trichiura and Trichuris sp. from Macaca sylvanus and T. trichiura from Papio papio are 14,091 bp, 14,047 bp and 14,089 bp in length, respectively. The three mt genomes are circular and consist of 37 genes-13 PCGs (cox1-3, nad1-6, nad4L, atp6, atp8 and cob), 22 transfer RNA genes (tRNAs), and two rRNAs (rrnL and rrnS). The molecular evidence presented here supports the hypothesis that T. trichiura de M. sylvanus (TMF31) and T. trichiura de P. papio (TPM1) were similar but genetically different with respect to Trichuris sp. from macaques (TMM5). The phylogenetic study also supported the evolution of the different Trichuris species. In conclusion, we suggest the existence of two cryptic species parasitizing M. sylvanus.

Innovation in wild Barbary macaques (Macaca sylvanus).

Project description:Innovation is the ability to solve novel problems or find novel solutions to familiar problems, and it is known to affect fitness in both human and non-human animals. In primates, innovation has been mostly studied in captivity, although differences in living conditions may affect individuals' ability to innovate. Here, we tested innovation in a wild group of Barbary macaques (Macaca sylvanus). In four different conditions, we presented the group with several identical foraging boxes containing food. To understand which individual characteristics and behavioural strategies best predicted innovation rate, we measured the identity of the individuals manipulating the boxes and retrieving the food, and their behaviour during the task. Our results showed that success in the novel task was mainly affected by the experimental contingencies and the behavioural strategies used during the task. Individuals were more successful in the 1-step conditions, if they participated in more trials, showed little latency to approach the boxes and mainly manipulated functional parts of the box. In contrast, we found no effect of inhibition, social facilitation and individual characteristics like sex, age, rank, centrality, neophobia and reaction to humans, on the individuals' ability to innovate.

Asymmetries in mother-infant behaviour in Barbary macaques (Macaca sylvanus).

Project description:Asymmetries in the maternal behaviour and anatomy might play an important role in the development of primate manual lateralization. In particular, early life asymmetries in mother's and infant's behaviour have been suggested to be associated with the development of the hand preference of the offspring. The aim of this study was to investigate the presence of behavioural asymmetries in different behavioural categories of mother-infant dyads of zoo-living Barbary macaques (Macaca sylvanus). The study subjects were 14 Barbary macaques involved in seven mother-infant dyads housed in Parco Natura Viva, Italy. For the mothers, bouts of hand preference for maternal cradling and infant retrieval were collected. For the infants, we focused on nipple preference and hand preference for clinging on mother ventrum. Moreover, we collected bouts of hand preference for food reaching in both groups. No significant group-level bias was found for any of the behavioural categories in either mothers or infants. However, at the individual level, six out of seven mothers showed a significant cradling bias, three toward the right hand and three toward the left hand. Moreover, all infants showed a significant nipple preference, six toward the mother's right nipple, one toward the left nipple. Furthermore, a significant correlation was found between the infant nipple preference and their hand preference for food reaching, suggesting that maternal environment rather than behaviour might affect the development of hand preference in Old World monkeys. Our findings seem partially to add to previous literature on perceptual lateralization in different species of non-primate mammals, reporting a lateral bias in mother-infant interactions. Given the incongruences between our study and previous research in great apes and humans, our results seem to suggest possible phylogenetic differences in the lateralization of mothers and infants within the Primates order.

Complete mitochondrial genome of an olive baboon (Papio anubis) from Gombe National Park, Tanzania.

Project description:The olive baboon (Papio anubis) is the most widely distributed baboon species. We report here on the complete mitochondrial genome of an olive baboon from the south-eastern edge of the species' range from Gombe National Park (NP), Tanzania. The genome (GenBank accession number MG787545) has a length of 16,490?bp and exhibits the typical structure of mammalian mitochondrial genomes. Phylogenetically, the olive baboon from Gombe NP is most closely related to eastern P. anubis, northern P. cynocephalus and P. hamadryas. The data are an important addition to further clarify the phylogeography of baboons and phylogeny of papionins in general.

Trichuris trichiura isolated from Macaca sylvanus: morphological, biometrical, and molecular study.

Project description:BackgroundRecent studies have reported the existence of a Trichuris species complex parasitizing primate. Nevertheless, the genetic and evolutionary relationship between Trichuris spp. parasitizing humans and Non-Human Primates (NHP) is poorly understood. The hypothesised existence of different species of Trichuris in primates opens the possibility to evaluate these primates as reservoir hosts of human trichuriasis and other putative new species of whipworms.ResultsIn this paper, we carried out a morphological, biometrical and molecular study of Trichuris population parasitizing Macaca sylvanus from Spain based on traditional morpho-biometrical methods, PCA analysis and ribosomal (ITS2) and mitochondrial (cox1 and cob) DNA sequencing. Morphological results revealed that Trichuris sp. from M. sylvanus is Trichuris trichiura. Ribosomal datasets revealed that phylogenetic relationships of populations of Trichuris sp. from M. sylvanus were unresolved. The phylogeny inferred on mitochondrial datasets (partitioned and concatenated) revealed similar topologies; Thus, phylogenetic trees supported the existence of clear molecular differentiation between individuals of Trichuris sp. from M. sylvanus appearing in two different subclades.ConclusionsBased on morphological parameters, biometrical measurements, and molecular sequence analysis, we conclude that the whipworms isolated from M. sylvanus were T. trichiura. Further, the evolutionary relationship showed that these worms belonged to two genotypes within the T. trichiura lineage. Since T. trichiura is of public health importance, it is important to carry out further studies to improve the understanding of its hosts range, evolution and phylogeography.

Phylogeography of Barbary macaques (Macaca sylvanus) and the origin of the Gibraltar colony.

Project description:The Barbary macaque (Macaca sylvanus) is the earliest offshoot of the genus Macaca and the only extant African representative, all other species being Asiatic. Once distributed throughout North Africa, M. sylvanus is now restricted to isolated forest fragments in Algeria and Morocco. The species is threatened; the maximum total wild population size is estimated at 10,000 individuals. Relationships among surviving wild subpopulations in Algeria (96 samples) and Morocco (116 samples) were examined by using 468-bp sequences from hypervariable region I of the mitochondrial DNA control region. Twenty-four different haplotypes were identified, differing by 1-26 mutational steps (0.2-5.6%) and 1 insertion. With one exception (attributable to secondary introduction in coastal Morocco), Algerian and Moroccan haplotypes are clearly distinct. However, whereas Moroccan subpopulations show little divergence in hypervariable region I sequences and little correspondence with geographical distribution, there is a deep division between two main subpopulations in Algeria and one marked secondary division, with haplotypes generally matching geographical distribution. Accepting an origin of the genus Macaca of 5.5 million years ago, the Moroccan population and the two main Algerian subpopulations diverged approximately 1.6 million years ago. Distinction between Moroccan and Algerian haplotypes permitted analysis of the origin of the Gibraltar colony of Barbary macaques (68 samples; 30% of the population). It is generally held that the present Gibraltar population descended from a dozen individuals imported during World War II. However, the Gibraltar sample was found to include Algerian and Moroccan haplotypes separated by at least 16 mutational steps, revealing a dual origin of the founding females.

Complete Taiwanese Macaque (Macaca cyclopis) Mitochondrial Genome: Reference-Assisted de novo Assembly with Multiple k-mer Strategy.

Project description:The Taiwanese (Formosan) macaque (Macaca cyclopis) is the only nonhuman primate endemic to Taiwan. This primate species is valuable for evolutionary studies and as subjects in medical research. However, only partial fragments of the mitochondrial genome (mitogenome) of this primate species have been sequenced, not mentioning its nuclear genome. We employed next-generation sequencing to generate 2 x 90 bp paired-end reads, followed by reference-assisted de novo assembly with multiple k-mer strategy to characterize the M. cyclopis mitogenome. We compared the assembled mitogenome with that of other macaque species for phylogenetic analysis. Our results show that, the M. cyclopis mitogenome consists of 16,563 nucleotides encoding for 13 protein-coding genes, 2 ribosomal RNAs and 22 transfer RNAs. Phylogenetic analysis indicates that M. cyclopis is most closely related to M. mulatta lasiota (Chinese rhesus macaque), supporting the notion of Asia-continental origin of M. cyclopis proposed in previous studies based on partial mitochondrial sequences. Our work presents a novel approach for assembling a mitogenome that utilizes the capabilities of de novo genome assembly with assistance of a reference genome. The availability of the complete Taiwanese macaque mitogenome will facilitate the study of primate evolution and the characterization of genetic variations for the potential usage of this species as a non-human primate model for medical research.
