Abstract

Toxocariasis is one of zoonosis diseases that caused by Toxocara spp. that is Toxocara canis. Toxocara canis has several stages until it can infect animals and humans, namely the egg stage, larvae first stage (L1), larvae second stage (L2), larvae third stage (L3) to adult worms. Studies about the L2 and L2 tissue of T. canis found in paratenic hosts using Scanning Electron Microscopy (SEM) have not been widely performed. Some of the causes include L2 being not easily to found and identified, so research rarely raises the ultrastructural morphology of L2 and L2 tissues. Knowledge about the ultrastructural morphology of L2 and L2 tissue of T. canis worms is very important to determining the diagnosis, especially the etiological diagnosis. The purpose of this study is to detected morphology of L2 and L2 tissues of T. canis using SEM. Samples from this study is faeces of dogs that infected with toxocariasis and the digestive tract of dogs obtained from dog slaughter houses. The sample is an adult worm of T. canis; the female worm is dissected and taken uterus to collect worm eggs. The results of this study on microscopic and optilab examination showed a difference between L2 and L2 tissue that the length of L2 hatched from embryonic eggs was 390 ìm and with a width of 23.4 ìm at the midpoint of the body. Larvae second stage length from the infected somatic tissue is 410 ìm and the width is 22.5 ìm at the midpoint, and then difference in dorsal lip, cuticles, body ring, cervical alae, buccal capsul, tail.

Abstract

The aim of this research were to determine antigenicity, sensitivity, and specificity of Toxocara canisprotein used as antigen in indirect-ELISA for the detection antibody against the worm in the infected hostin order to proper diagnose kit. The design used was true experimental, with Post-test Only ControlGroups Design. Mouse was immunized with various worm homogenates used to antigenicity, sensitivityand specificity tests of T. canis protein with indirect-ELISA technique. The independence variable werevarious immunogens (homogenates); the dependence variables were antigenicity, sensitivity and specificityvalues interpreted by optical density (OD) value of mouse sera; and controlled variable were mouse strain,feed and retrieval time of sera. The result showed that OD values of mouse sera immunized with T. canisand T.cati homogenate were signicantly difference (p<0.01) as compared to those immunized withAncylostoma spp., Dipylidium caninum and control sera. Using the diagnosis based on the finding ofToxocara, the sensitivity of OD value by ELISA result from mouse sera immunized with Toxocara spp.homogenate were 100%. Using negative OD value by ELISA from mouse sera immunized with Ancylostomaspp. and D. caninum homogenate, the specificity of the test was 87.5%. In conclusion, protein of T.canishas the same antigenicity against anti-T. canis and anti-T. cati sera, but they had the lower antigenicityagainst anti-Ancylostoma spp. and anti-D.caninum sera. As the sensitivity value of 100% and specificityvalue of 87.5%, in detecting antibody against toxocariasis, the possibility of obtaining false positive was12.5%.

Abstract

Fasciolosis is one of the endemic parasitic diseases in Indonesia. Fasciola gigantica is the main species found to infect livestock, especially beef cattle. The purpose of this study was to analyze the morphometry and identify the ultrastructure morphology of the F. gigantica worm isolated from beef cattle in Berau abattoir. The F. gigantica worms were isolated from two cattle breeds, namely Donggala cattle and Bali cattle. Worm was stained by using carmine methode to analyze the morphometric of the worm and scanning electron microscopy to identify ultrastructure morphology. Morphometric of the worm was analysed with the one sample t-test and multidimensional scaling statistical methods. The results of the morphometric analysis showed that F. gigantica from both breeds had significant differences (P<0.05) between the parameters and based on multidimensional scaling analysis had similarities with F. intermedia from Iran. Based on scanning electron microscopy examination showed that F. gigantica from the Donggala cattle breed was infected with type 1 of F. gigantica while F. gigantica from the Bali cattle breed was infected with type 2 of F. gigantica based on ventral sucker, oral sucker, and spine. It can be concluded that F. gigantica found in beef cattle in Berau was type 1 F. gigantica (Donggala cattlebreed) and type 2 F. gigantica (Bali cattle breed) and similar with F. intermedia from Iran.
