“…Although human sparganosis has been reported in neighboring countries such as Myanmar [ 48 ] and India [ 49 ], Spirometra information in Bangladesh is limited, and genetic analysis has not been done on the species. From a heavily infected lion, we successfully extracted the DNA of the spirometriid eggs isolated from fecal samples.…”

“…However, the taxonomy of the genus Spirometra is still unclear, and there is considerable controversy in the literature [ 47 ]. Although S. decipiens from Korea [ 50 ], S. ranarum from Myanmar [ 48 ], and S. erinaceieuropaei from China [ 45 ] were reported and claimed as individual species, some researchers reported S. decipiens and S. ranarum as synonyms of S. erinaceieuropaei [ 51 , 52 ]. In addition to morphological differences, Jeon et al [ 48 ] analyzed the mitochondrial genomes of three Spirometra spp.…”

Introduction: Endoparasites in captive wildlife might pose a threat to public health; however, very few studies have been conducted on this issue, and much remains to be learned, especially in limited-resource settings. This study aimed to investigate endoparasites of captive wildlife in Bangladesh. Perception and understanding of veterinarians regarding one health and zoonoses were also assessed. Materials and Methods: A cross-sectional study was conducted from October 2019 to August 2020. A total of 45 fecal samples from 18 different species of wild animals (i.e., 11 species of mammals: herbivores, carnivores, and omnivores, six birds, and a single reptile species) were collected randomly. Parasitological assessments were done by modified formalin ether sedimentation technique and rechecked by Sheather’s sugar floatation technique. Molecular identification of Spirometra spp. was conducted by amplifying the cytochrome c oxidase 1 (cox1) gene. Questionnaire surveys among 15 veterinarians and an in-depth interview (IDI) with a zoo officer were conducted. Results: Helminths (Spirometra sp., Capillaria sp., Ascaridia/Heterakis, opisthorchiid, strongyles, acuariid, hookworms, roundworms, and unidentified nematode larvae) and protozoa (coccidian oocyst) were identified, and the overall prevalence was 48.9% (22/45). The cox1 sequences (341 bp) of the Bangladesh-origin Spirometra species from lion showed 99.3–99.7% similarity to the reference sequences of Spirometra decipiens (GenBank No: KJ599679.1; MT122766). The majority of study participants (86.6%) agreed about the importance of endoparasite control in zoo animals, and 73.3% expressed that the one health concept should be promoted in Bangladesh. Only 6.7% of veterinarians perceived confidence in diagnosing parasitic diseases and preventing antiparasiticidal resistance. Conclusions: In the present survey, we found a considerable prevalence of endoparasites in captive wildlife. For the first time, zoonotically important S. decipiens from lion was molecularly characterized in Bangladesh. Veterinarian training is required to improve parasite control knowledge and practice. This study highlights the need for routine parasitological assessment, promotion of one health, and improvement of the implementation of current parasite control strategies in zoo animals.

“…4,5 Stimuli-responsive polymers offer significant opportunities for implementing a range of smart, adaptive and dynamic behaviors in response to temperature, light, electromagnetic fields, and chemicals. [6][7][8][9][10][11][12] As one of the most widely used stimuli-responsive materials, thermally responsive poly N-isopropylacrylamide (pNIPAM) has been utilized to create a range of shape-changing structures including grippers, 13,14 propellers, 15,16 and actuators. [17][18][19] When coupled with 3D printing, a high level of customization, tunability and adaptability can be achieved.…”

The distribution of periodic patterns of materials with radial or bilateral symmetry is a universal biological design principle. Amongst the many biological forms, tubular shapes are a common motif in many organisms, and they are also important for bioimplants and soft robots. However, the simple design principle of strategic placement of 3D-printed segments of swelling and nonswelling materials to achieve widely different functionality has yet to be demonstrated. Here, we

“…The mitochondrial DNA (mtDNA) information has been used for classification, phylogenetic reconstruction, taxonomic identification, and population genetics of the order diphyllobothridea [14,15]. Few Spirometra species have been used for genetic variation, taxonomy, and phylogenetic studies by using mtDNA sequences such as cytochrome c oxidase subunit 1 and 3 (cox1 and cox3), NADH dehydrogenase subunit 1, 3, and 4 (nad1, nad3, and nad4) [16][17][18][19][20]. Nevertheless, among the Spirometra species recovered from various carnivorous mammals in Tanzania, there is no detailed molecular information, particularly in the whole mtDNA sequences on Spirometra species.…”

This study was carried out to provide information on the taxonomic classification and analysis of mitochondrial genomes of Spirometra theileri. One strobila of S. theileri was collected from the intestine of an African leopard (Panthera pardus) in the Maswa Game Reserve, Tanzania. The complete mtDNA sequence of S. theileri was 13,685 bp encoding 36 genes including 12 protein genes, 22 tRNAs and 2 rRNAs with absence of atp8. Divergences of 12 protein-coding genes were as follow: 14.9% between S. theileri and S. erinaceieuropaei, 14.7% between S. theileri and S. decipiens, and 14.5% between S. theileri with S. ranarum. Divergences of 12 proteins of S. theileri and S. erinaceieuropaei ranged from 2.3% in cox1 to 15.7% in nad5, while S. theileri varied from S. decipiens and S. ranarum by 1.3% in cox1 to 15.7% in nad3. Phylogenetic relationship of S. theileri with eucestodes inferred using the maximum likelihood and Bayesian inferences exhibited identical tree topologies. A clade composed of S. decipiens and S. ranarum formed a sister species to S. erinaceieuropaei, and S. theileri formed a sister species to all species in this clade. Within the diphyllobothridean clade, Dibothriocephalus, Diphyllobothrium and Spirometra formed a monophyletic group, and sister genera were well supported.
