Penelitian mengenai jenis-jenis mamalia yang mengunjungi kubangan babi hutan di hutan konservasi PT Tidar Kerinci Agung dan PT Kencana Sawit Indonesia, Solok Selatan, Sumatera Barat telah dilaksanakan dari 15 Juni sampai dengan 8 Desember 2015. Penelitian dilakukan dengan pemasangan tujuh buah perangkap kamera di sekitar kubangan babi hutan. Selama penelitian didapatkan 18 jenis hewan mamalia dari 12 famili dan 5 ordo. Hewan mamalia yang sering mengunjungi kubangan babi hutan yaitu Sus scrofa (481 foto), Macaca nemestrina (476 foto), Sus barbatus (269 foto), Macaca fascicularis (38 foto) dan Muntiacus muntjak (33 foto). Penelitian ini menunjukkan bahwa kubangan babi hutan menarik bermacam-macam jenis mamalia dengan frekuensi kunjungan yang berbeda-beda.

AbstractContrast sensitivity functions reveal information about a subject’s overall visual ability and have been investigated in several species of nonhuman primates (NHPs) with experimentally induced amblyopia and glaucoma. However, there are no published studies comparing contrast sensitivity functions across these species of normal NHPs. The purpose of this investigation was to compare contrast sensitivity across these primates to determine whether they are similar. Ten normal humans and eight normal NHPs (Macaca fascicularis) took part in this project. Previously published data from Macaca mulatta and Macaca nemestrina were also compared. Threshold was operationally defined as two misses in a row for a descending method of limits. A similar paradigm was used for the humans except that the descending method of limits was combined with a spatial, two-alternative forced choice (2-AFC) technique. The contrast sensitivity functions were fit with a double exponential function. The averaged peak contrast sensitivity, peak spatial frequency, acuity, and area under the curve for the humans were 268.9, 3.40 cpd, 27.3 cpd, and 2345.4 and for the Macaca fascicularis were 99.2, 3.93 cpd, 26.1 cpd, and 980.9. A two-sample t-test indicated that the peak contrast sensitivities (P = 0.001) and areas under the curve (P = 0.010) were significantly different. The peak spatial frequencies (P = 0.150) and the extrapolated visual acuities (P = 0.763) were not different. The contrast sensitivities for the Macaca fascicularis, Macaca mulatta, and Macaca nemestrina were qualitatively and quantitatively similar. The contrast sensitivity functions for the NHPs had lower peak contrast sensitivities and areas under the curve than the humans. Even though different methods have been used to measure contrast sensitivity in different species of NHP, the functions are similar. The contrast sensitivity differences and similarities between humans and NHPs need to be considered when using NHPs to study human disease.

Fertilisation and development of IVM non-human primate oocytes is limited compared with that of in vivo-matured (IVO) oocytes. The present study describes the IVM of macaque oocytes with reference to oocyte glutathione (GSH). Timing of maturation, comparison of IVM media and cysteamine (CYS) supplementation as a modulator of GSH were investigated. A significantly greater proportion of oocytes reached MII after 30 h compared with 24 h of IVM. Following insemination, IVM oocytes had a significantly lower incidence of normal fertilisation (i.e. 2PN = two pronuclei and at least one polar body) and a higher rate of abnormal fertilisation (1PN = one pronucleus and at least one polar body) compared with IVO oocytes. Immunofluorescence of 1PN zygotes identified incomplete sperm head decondensation and failure of male pronucleus formation as the principal cause of abnormal fertilisation in IVM oocytes. The IVO oocytes had significantly higher GSH content than IVM oocytes. Cumulus-denuded oocytes had significantly lower GSH following IVM compared with immature oocytes at collection. Cysteamine supplementation of the IVM medium significantly increased the GSH level of cumulus-intact oocytes and reduced the incidence of 1PN formation, but did not improve GSH levels of the denuded oocyte. Suboptimal GSH levels in macaque IVM oocytes may be related to reduced fertilisation outcomes.

Pendahuluan: Plasmodium knowlesi merupakan agen malaria yang mulanya hanya menginfeksi kera, yakni kera ekor panjang (Macaca fascicularis) dan kera ekor babi (Macaca nemestrina). P. knowlesi  telah berkembang untuk menginfeksi secara zoonotik, yaitu ditransmisikan dari hewan kepada manusia oleh vektor nyamuk Anopheles betina. Sejak kejadian endemik malaria knowlesi pertama pada tahun 2004 di Serawak, Malaysia, jumlah kasus infeksi P. knowlesi meluas dan meningkat hingga hampir ke seluruh wilayah di Asia Tenggara, termasuk Indonesia. Peningkatan kasus infeksi P. knowlesi merupakan hasil interaksi yang kompleks antara manusia, agen, dan lingkungan. Faktor individu dan lingkungan merupakan faktor risiko malaria knowlesi. Siklus hidup P. knowlesi sangat singkat dan cenderung menginfeksi semua jenis eritrosit bersama dengan spesies Plasmodium lainnya (infeksi campuran). Morfologi dan gejala klinis P. knowlesi sangat mirip dengan spesies Plasmodium lain, membuatnya sulit didiferensiasi dan turut memengaruhi peningkatan kasus infeksi. Diagnosis malaria knowlesi dengan teknik molekuler PCR merupakan metode yang paling akurat saat ini. Pengobatan terhadap malaria knowlesi harus segera dilakukan untuk mencegah progresivitas menjadi malaria berat hingga kematian. Tujuan: Artikel ini bertujuan untuk mempelajari epidemiologi, faktor risiko, siklus hidup, morfologi, gejala klinis, diagnosis dan tatalaksana terbaru terhadap kasus malaria knowlesi, terutama di Indonesia. Metode: Penulisan artikel menggunakan metode tinjauan pustaka dari berbagai literatur mengenai malaria knowlesi.     Diskusi: Pengetahuan akan epidemiologi, faktor risiko, siklus hidup, morfologi, gejala klinis, diagnosis, dan tatalaksana terhadap kasus malaria knowlesi dapat menambah informasi untuk perkembangan penelitian terhadap distribusi dan pengendalian kasus malaria knowlesi. Artikel ini diharapkan dapat membantu mempercepat target eliminasi malaria di Indonesia pada tahun 2030. Kata Kunci: Infeksi, malaria knowlesi, manusia, Plasmodium knowlesi

Morphological Differences

Comparative chromosome banding analysis and/or fluorescence in situ hybridization (FISH) studies are established approaches to compare human and ape chromosomes. FISH-banding is a relatively new and not routinely applied method suited very well to provide to a better understanding of the evolutionary history of primate and human phylogeny. Here multicolor banding (MCB) applying probes derived from Homo sapiens was used to analyze the chromosomes of Thai crab-eating macaque (Macaca fascicularis). The results agree with those of previous studies in other macaques, e.g. Macaca sylvanus or Macaca nemestrina. This result pinpoints, that morphological differences within the Ceropithecoidae must be founded rather in subchromosomal changes or even in epigenetics than in gross structural alterations.

Forest for special purpose of Aek Nauli is an highland rainforest as habitat for primates and tourism area in Marsose, Sibaganding Village, Simalungun, Lake Toba Geopark in North Sumatra. As an endangered and protected species, siamang (Sympalangus syndactylus syndactylus) in the same habitat as pig-tailed macaque (Macaca nemestrina) and long-tailed macaque (Macaca fascicularis). Nowadays, the siamang population is declining due to the conversion of forest to non-forests, forest fragmentation and illegal trade. Long-tailed macaque and pig-tailed macaque are agricultural pests that are economically harmful to communities around the forest. The primate population data is needed as input for the sustainable management strategy by stakeholders to further preserve forest areas and primate populations. This study was carried out for 3 months from May to July 2018. To determine the number of primate populations performed by the concentrated area method. Estimates of primate populations are: A. Siamangs; 1 group with 3 individuals, population size 0.06. Age structure of population 1 juvenile 1, 2 adults. B. Pig-tailed macaque; 3 groups with 65 individuals, population size 1.1. The age structure is 17 tillers, 17 adolescents and 31 adults. C. Long-tailed macaque; 3 groups with 23 individuals, population size 0.5. Age structure of 5 tillers, 7 adolescents and 11 adults.
