studies on trypanosomes in the taiwan monkey.fifty-three or 9% of 594 taiwan monkeys, macaca cyclopis, were found infected with a trypanosome species. the parasites were recovered from monkey blood in diaphasic blood-agar culture medium with a locke's solution overlay. trypanosomes were found on only a few thick blood smears and no dividing or multiplying forms were found. some of the organisms had a free-flagellum (4.7 microns), an undulating membrane and both ends of the body were pointed. the total length averaged 41.7 microns; nucleus ...19836673131
efficiency of coding in macaque vocal communication.a key characteristic of human language efficiency is that more frequently used words tend to be shorter in length-the 'law of brevity'. to date, no test of this relationship between frequency of use and length has been carried out on non-human animal vocal communication. we show here that the vocal repertoire of the formosan macaque (macaca cyclopis) conforms to the pattern predicted by the law of brevity, with an inverse relationship found between call duration and rate of utterance. this findi ...201020106854
antibodies to epstein-barr virus in a burkitt's lymphoma cell line in taiwan monkeys (macaca cyclopis).the prevalence of taiwan monkeys with antibodies to epstein-barr virus, as detected by the indirect immunofluorescence technique, was lower than that of healthy persons in taiwan.19714324196

infection of newborn taiwan monkeys (macaca cyclopis) with human adenovirus type 12 and simian virus 40.for testing biological response of newborn taiwan monkeys to infection of human adenovirus type 12 (ad12) and simian virus 40 (sv40), 40 newborn taiwan monkeys were inoculated with ad12, ad12, plus sv40, ad12 supplemented with ad12-induced hamster tumor tissue (ad12 tumor) or control specimens (hela or african green monkey kidney cell lysate). among them 26 survived including 8 newborn monkeys inoculated with control specimens. the survivors were observed for 4 years but no tumor was produced. t ...1975181217
experimental transmission of wuchereria bancrofti to monkeys.infective larvae of wuchereria bancrofti from laboratory-raised culex pipiens fatigans and aedes togoi mosquitoes fed on human volunteers in jakarta, indonesia (j strain) and kinmen island, china (k strain) were introduced into taiwan monkeys (macaca cyclopis) by subcutaneous inoculation, by foot puncture, or by permitting infected mosquitoes to feed weekly on the monkeys. some animals were splenectomized and others were treated with varying regimens of immunosuppressants. necropsy was done on m ...1979107818

first discovery of colobine fossils from the early to middle pleistocene of southern taiwan.here we report on two kinds of cercopithecid fossil monkeys (cercopithecinae and colobinae) from the early to middle pleistocene sediments of the chochen (=tsochen) area (tsailiao-chi or shinhua hill), southern taiwan. the fossil specimens include the first fossil record of colobine monkeys from taiwan, where only macaque monkeys now occur. all cercopithecine fossils were identified as macaca cf. macaca cyclopis, the extant taiwan macaque, except for one extremely large isolated upper molar, whi ...201222749256
complete taiwanese macaque (macaca cyclopis) mitochondrial genome: reference-assisted de novo assembly with multiple k-mer strategy.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 strate ...201526125617
non-maternal infant handling in wild formosan macaques of mount longevity, taiwan.in this paper, we present quantitative data on how the social network and sex of infants influence allomothering behaviour among wild formosan macaques, macaca cyclopis. using long-term field data collected from the mount longevity study site in kaohsiung (taiwan), we have tested relevant hypotheses incorporating data on age, rank and reproductive state of infant handlers, and the relationship between handlers and infants. the results support 2 major hypotheses, i.e. those of reciprocity and all ...201526820742
identification of recombination in the envelope gene of simian foamy virus serotype 2 isolated from macaca cyclopis.the full-length sequence of simian foamy virus serotype 2 (sfvmcy-2), isolated from a taiwanese macaque, was determined. sfvmcy-2 was highly related to sfv serotype 1 (sfvmcy-1), an isolate from the same species, except in the putative receptor binding domain (rbd) in env, which contained novel sequences related to sfv serotype 3 (sfvagm-3), isolated from an african green monkey. the results identify a potential region of neutralization in sfvs and demonstrate recombination between genetically d ...201323698303
molecular cloning and characterization of the circumsporozoite protein gene of plasmodium inui isolated from formosan macaques (macaca cyclopis) in taiwan.we characterized the complete nucleic and amino acid sequences of the plasmodium inui circumsporozoite protein (pincsp) gene and analyzed nucleotide diversity across the entire pincsp gene by using 7 field isolates and strains taiwan i and ii obtained from formosan macaques (macaca cyclopis) in taiwan. the length of the circumsporozoite protein ( csp ) gene ranged from 1077 to 1125 bp. size polymorphisms were due to variations in the number of tandem repeat units. the non-repetitive (nr) region ...201021158626
prevalence and molecular characterization of plasmodium inui among formosan macaques (macaca cyclopis ) in taiwan.since the 1970s, no information on simian malaria has been documented in taiwan, an area that is free from human malaria. to update the prevalence of simian malaria, a molecular-based survey was performed. blood samples from 286 formosan macaques ( macaca cyclopis ) were tested for plasmodium species by microscopy and nested polymerase chain reaction. furthermore, the field isolates were characterized by sequencing the 42-kda fragment of the merozoite surface protein 1 (msp-1(42)). of the 286 bl ...201019712012
interactions between visitors and formosan macaques (macaca cyclopis) at shou-shan nature park, taiwan.ecotourism involving feeding wildlife has raised public attention and is a controversial issue, especially concerning nonhuman primates. between july 2002 and april 2005, the behavior of monkeys and tourists was collected through scan samplings, focal samplings and behavior samplings at the shou-shan nature park located in taiwan's second largest city--kaohsiung. in addition, the number of tourists and monkeys was counted in different hours and places within the park. four hundred visitors were ...200919051313
prevalence of antibody reaction with cercopithecine herpesvirus 1 antigen in macaca cyclopis, macaca fascicularis, and papio anubis in taiwan.a total of 284 non-human primate sera were collected between december 2004 and september 2005 and tested by a commercially available dot immunobinding assay for the antibodies to cercopithecine herpesvirus 1, an alphaherpesvirus with high mortality for infected humans.200717976038
within-group female-female agonistic interactions in taiwanese macaques (macaca cyclopis).feeding-related agonism among wild female taiwanese macaques was investigated in two study groups at ecologically diverse sites (fu-shan and ken-ting) to determine whether contest-feeding competition was present in these groups. females that contest for food within a primate group are hypothesized to form dominance hierarchies and tend to be philopatric. in this study we tested 1) whether taiwanese macaque females show higher agonism in a feeding context, 2) whether they exhibit stronger agonism ...200717154380

high incidence of supernumerary nipples and twins in formosan macaques (macaca cyclopis) at mt. longevity, taiwan.a population of formosan macaques at mt. longevity exhibits an unusually high incidence of supernumerary nipples (polythelia: between 1-6 accessory nipples and/or areolae on 33% of adults), as well as a high rate of twinning (about 1% of births). the coexistence of these unusual traits suggests a connection, which is further supported by a tendency for mothers of twins to have accessory nipples and for twins to be born in troops with high incidence of polythelia.200011132113
