Background and Aim: Worms from nematodes are the most numerous and the most detrimental in elephants. Most adult worms are located in the digestive tract. Nematode infection is at higher risk in young elephants, which caused several cases such as anemia, hypoalbuminemia, enteritis, and even death. This study aimed to determine the morphology and morphometry of adult nematodes on Sumatran elephants in Way Kambas National Park area. Materials and Methods: Nematode samples were obtained from Sumatran elephants' feces (Elephas maximus sumatranus) in Way Kambas National Park, Lampung Province, after being given Kalbazen® containing albendazole 1000 mg at a dose of 10 mg/kg by the veterinarian in charge of the National Park area. For the morphological and morphometric examinations, we used an Olympus BX 51 microscope equipped with Olympus DP 12 camera and were conducted at the Parasitology Laboratory, Faculty of Veterinary Medicine, Universitas Gadjah Mada. The scanning electron microscopic (SEM) analysis was carried out at the Biology Research Center of the Indonesian Institute of Sciences (Lembaga Ilmu Pengetahuan Indonesia). Results: The results of macroscopic observations of the obtained nematodes showed that the nematodes which were found have the characteristics of round, slim, and white color. The size of a female worm was larger than a male worm. Microscopic examination in four anterior papillae indicated that the dorsal lobe in the copulatory bursa was longer than lateral lobe. The result of inspection with the SEM showed a leaf crown consisting of 10 elements, a pair of amphids laterally, and two pairs of papilla in a submedian region. Conclusion: Based on our morphology and morphometry examinations of adult nematodes in Sumatran elephant (E. maximus sumatranus) in Way Kambas National Park area, the adult nematodes which were found are species of Quilonia travancra.

The Many

Sumatran elephants (Elephas maximus sumatranus) is one of the many wild animals been domesticated, but so far there is no criteria for that propose. This research is a prelimenary effort in providing those criteria. This research began in April to May 2013.  The first step was to establish the norm of Suitable range of as many as 17 variables required for upholding the elephant life domestication area.  The Suitable norm range we determined through an exhausted study of previous researchs or literature available.  The next step was to determined the Less Suitable and the Not Suitable norms range for those 17 variables employed, e.i. by deviating by 25% and by 50% from the Suitable norm range respectively. The second step, we employed a Delphi Method in order to validate and refinary the three catagorical norms range of the 17 varibles concerned by mean of asking to some elaphant experts in our country.  We, then applied the deemed criteria to evaluate a practice of ephants management at The Sumatra Elephant Conservation Center (PKG) and the Elephant Response Unit (ERU), Way Kambas National Park. The research results: (1) We obtained the prelimenary criteria  as a rubric for Sumatran elephant domestication, and (2) The elephant nurturing practices at PKG and ERU were Suitable, except for the variables of population density, home range and elephant shading.

Indonesia has a high wealth of  flora and  fauna, wealth is necessary guarded and preserved, one of the wealth fauna owned Indonesia is Sumatran Elephant (Elephas maximus sumatranus) . This study aims to record the daily behavior of Sumatran Elephant (Elephas maximus sumatranus) in Elephant Response Unit Way Kambas National Park Lampung. The method used is focal animal sampling. The method was chosen because it allows the observer to record any behavior that occurs suddenly and quickly by recording animal behavior at certain time intervals. The results obtained from six individual tame elephants that became objects named Karnangin, Aditya, Dona, Wulan, Elena, and Cory consisted of 13 daily behaviors which were dominated by eating. Daily behavior found differences on adult male elephants named Karnangin and Aditya commonly used for patrol activities and when not patrolling. Sumatran elephants need food availability like green plants in their habitat, because less perfect digestion of these animals requires very large amounts of food, 200 - 300 kg of biomass per day for each adult elephant tail or 5-10% of his body weight.Keywords: Daily Behavior, Focal Animal Sampling, Sumatran Elephants

Essential Contribution

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.  It shares its border with 22 of 37 villages surrounding the national park.  Understanding their existence in the wild is a priority, and  wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.  Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.  Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort.  Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.  Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.  Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

AbstractCorn starch/polyvinyl alcohol (PVA)/glycerol composite films incorporated with ε-polylysine were prepared, and their properties were investigated. The Fourier-transform infrared (FTIR) spectroscopy indicated that the interactions happened between the amino group of ε-polylysine and hydroxyl group starch/PVA composite films. X-ray diffraction (XRD) analysis showed that the addition of ε-polylysine decreased the intensity of all crystal peaks. Thermogravimetric (TGA) analysis suggested that ε-polylysine improved the thermal stability of composite films. Scanning electron microscopic (SEM) analysis showed that the upper surface of composite films incorporated with ε-polylysine presented more compact and flat surface. The antimicrobial activity of the composite film progressively increased with the increasing of ε-polylysine concentration (P < 0.05). The tensile strength, elongation at break and water absorption significantly increased, whereas water solubility decreased with the increasing of ε-polylysine concentration (P < 0.05). Therefore, the corn starch/PVA/glycerol composite films incorporated with ε-polylysine had good mechanical, physical and antimicrobial properties and could have potential application as a novel antimicrobial packaging material.

AbstractSchistosomiasis is one of the most devastating parasitic disease in the world. Schistosoma spp. survive for decades within the vasculature of their human hosts. They have evolved a vast array of mechanisms to avoid the immune reaction of the host. Due to their sexual dimorphism, with the female worm lying within the gynecophoric canal of the male worm, it is the male that is exposed to the immediate environment and the soluble parts of the host’s immune response. To understand how the worms are so successful in fending off the immune attacks of the host, comparative analyses of both worm sexes in human serum (with or without Praziquantel) were performed using scanning electron microscopy, transmission electron microscopy, and immunohistochemistry. Further, gene expression analyses of tegument-specific genes were performed. Following the incubation in human serum, males and females out of pairs show morphological changes such as an altered structure of the pits below the surface and an increased number of pits per area. In addition, female schistosomes presented a marked tuft-like repulsion of their opsonized surface. The observed resistance of females to Praziquantel seemed to depend on active proteins in the human serum. Moreover, different expression profiles of tegument-specific genes indicate different functions of female_single and male_single teguments in response to human serum. Our results indicate that female schistosomes developed different evasion strategies toward the host’s immune system in comparison to males that might lead to more robustness and has to be taken into account for the development of new anti-schistosomal drugs.
