Xenochrophis piscatoris a snake that often found in Indonesia, particularly in Java Island.Xenochrophis piscatoris a non-venomous snake and often used for food, traditional medicine and as pets in Indonesia. Snakes can be infected by different types of parasites which are zoonotic. One of the zoonotic helminth infect snakes is acanthocephalan. Acanthocephalan can be transmitted to humans by ingesting snake products. We investigate the incidence of helminthiasis in X. piscator from snakes collector in Tulangan district, Sidoarjo, East Java. Parasites were collected from X. piscator organs. Identification of parasites was in carmine stain using light microscope for examination. Sixty snakes were observed and sixteen snakes were positively infected by adult acanthocephalan (26.67%). Acanthocephalan was found in mesenterium and fascia of X. piscator.

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.

Ascaridiasis can be happened in either broiler or hens that can caused decrease of meat and egg productions. Ascaridiasis is a parasite that is most often found in poultry and cause high economic losses. This research was conducted to determine the anthelmintic effect of calcium hydroxide [Ca(OH)₂] on mortality of Ascaridia galli in vitro. In this research used Ascaridia galli with length 7-11 cm without differentiating their sex. The concentrations of calcium hydroxide [Ca(OH)₂] for immersion the Ascaridia galli were 0,01%, 0,02%, 0,025% and 0,03% as treatment group, respectively. The negative control used aquadest. Observation death A.galli worm and analysis of the data at the 2 hour, 4 hour, 6 hour, 8 hour, 10 hour and 12 hour. The result showed that the increase of concentration increased mortality of Ascaridia galli. Percentage of death worm A.galli at the 12th hour on concentration ,01%, 0,02%, 0,025% and 0,03% was 20%, 55%, 75% and 100%. ANOVA test showed significant difference between control and treatment group (p<0.05). Duncan multiple range test was seen the best treatment was the biggest mortality in concentration of 0,03%.
