“…A infecção por ascarídeos é uma das mais importantes para serpentes, a qual pode ser fatal (BECK et al, 2006;RATAJ et al, 2011). A maioria dos ascarídeos tem ciclo de vida indireto e Ophidascaris está entre os gêneros mais conhecidos, o qual pode causar gastrite granulomatosa e caseosa em serpentes, capaz de levar a um mal funcionamento gástrico e regurgitação nesses animais (GREGO et al, 2004;LI et al, 2014;MELLO et al, 2017). A transmissão em cativeiro é rara, mas não pode ser descartada (DIAS et al, 2004), visto que foi o nematódeo mais frequente, assim como o observado por outros autores em C.durissus e B.alternatus (ARAÚJO et al, 1999).…”

“…Some researchers had identified Ophidascaris species. Differential features of lip shape, esophageal length and spicules, tail, the number and arrangement of paracloacal and postcloacal papillae, and egg morphology are commonly used to recognize different species of Ophidascaris [ 9 ]. Ophidascaris durissus had found from Crepitus durissus snake in Brazil [ 6 ], Ophidascaris filaria was found in an Indian python in Sistan [ 10 ], and Ophidascaris excavata was found in the pit viper Gloydius brevicaudus in the Republic of Korea [ 11 ].…”

Aim:The study was conducted to describe the morphology and morphometry of nematode worm in the stomach of Xenochrophis piscator snake macroscopically and microscopically using light and scanning electron microscopy (SEM).Materials and Methods:The sample was 40 nematode worms that have been collected from 60 snakes which slaughtered at snake slaughterhouses in Sidoarjo, Indonesia. The worms (10 male and 10 female) were stained with carmine, and the others were sent to Indonesian Science Institute for ultrastructure observation by SEM. Some of the female worms were immersed in physiological NaCl and incubated to collect the worm eggs.Results:Nematode worm in this study had three lips with almost the same size and it had papillae, so it was included in ascaridoid. The mouth of ascaridoids has three lips, the dorsal bearing two large outer papillae and the each lateroventral with one papilla. The body length and width of the male worm were 70-105 mm and 0.92-1.32, respectively, with head diameter of 0.22-0.28 mm. Dorsal and ventrolateral lips almost have the same size that was 0.10-0.12×0.11-0.13 mm. The length of interlabia was 0.06-0.08 mm, esophagus was 3.21-4 mm, tail was 0.17-0.23 mm, and spicule was 2.12-3.36 mm. The body length and width of the female worm were 85-130 mm and 1.28-1.71 mm, respectively. The head diameter was 0.29-0.38 mm. Dorsal and ventrolateral lips almost have the same size that was 0.13-0.16×0.15-0.19 mm. The interlabial length was 0.08-0.10 mm, esophagus was 3.04-4.67 mm, and tail was 0.22-0.31 mm. The distance of the vulva from the anterior edge was 56-88 mm with an average of 67.35 mm. The eggs have conspicuously pitted with length 0.08-0.09 mm and width 0.07-0.08 mm.Conclusion:Based on the characteristics of morphology and morphometry, the ascaroid worms found on X. piscator snake from Sidoarjo, Indonesia, were O. piscatori.

Members of genus Ophidascaris are common parasitic roundworms in snakes that cause gastric granulomas, adenocarcinomas, intestinal obstruction, death, and serious economic losses in snakes and their products. To identify molecular marker of Ophidascaris baylisi from the Burmese python (Python molurus bivittatus), we amplified internal transcribed spacer (ITS) sequence from this roundworm and analyzed their homology and phylogeny. The amplified ITS sequence length was 1140 bp, comprising the complete ITS1, 5.8S, and ITS2 sequences and a partial 28S sequence. The ITS1+ sequence was homologous (85.8% homology) to the related species Ophidascaris robertsi. The phylogenetic tree revealed a close genetic distance between O. baylisi and O. robertsi, which formed a separate branch within family Ascaridae clade. The results indicated that the identified ITS sequence could be a good molecular marker for further study on the molecular classification and genetic variation of Ophidascaris species.
