Cysticercus tenuicollis (C. tenuicollis) is the larval stage infection of Taenia hydatigena, a common tapeworm of dogs and other Canidae, which has a wide range of intermediate hosts including sheep, goat, cattle, deer, camel, horse, human and other wild ruminants, the disease spreads through a contaminated water, soil and food with feces of infected dogs or other carnivores, T. hydatigena lives in the intestinal of the definitive host (carnivores) and excretes a huge number of eggs with feces daily. The present study conducted to determine the prevalence rate and molecular characterization of C. tenuicollis among sheep and goats in Sulaimani province. A total of 14088 slaughtered animals were inspected postmortem from the new Sulaimani abattoir comprise, which involves 13395 sheep and 693 goats. The selected cysts were preserved in 70% Ethanol for DNA extraction and molecular study,  The mt-CO1 gene was amplified with a conventional polymerase chain reaction (PCR), the PCR product purified and DNA sequencing for reverse and forward strands was determined by a genetic analyzer, the obtained sequences aligned with the DNA sequences of T. hydatigena in Iran, Turkey and Palestine, which deposited in GenBank under the following accession number (JQ710588), (JN827307) and ( KM032284) respectively. The prevalence rate of C. tenuicollis was 2.63% in sheep and 2.58% in goats. This result shows no significant differences of C. tenuicollis between sheep and goats (p>0.05). The nucleotide sequence alignment of cytochrome oxidase subunit 1 (CO 1) gene revealed that the amplified DNA fragment is belong to Taenia hydatigena and Echinococcus granulosus and the nucleotide sequences of T. hydatigena deposited in GenBank under accession number (MH638348). This finding concludes that the amplification of mt-CO1 gene cannot be depended on discriminate hydatid cyst and C. tenuicollis while the partial DNA sequences of mt-CO1 gene are significantly valuable to differentiate C. tenuicollis from hydatid cyst, which is completely different in the pathology and control.

The conglutinating complement absorption test (CCAT) has been used to detect Cysticercus tenuicollis (Taenia hydatigena cysticercus) infection in sheep and goats. Sera from naturally infected sheep and goats showing a titre above 1:40 were considered positive for cysticercosis. Experimentally infected lambs gave a higher antibody response than sheep and goats.

AbstractUrocleidoides ectoparasites are mainly found on fish of the neotropical regions. Although molecular research on monogeneans is available, no genetic data exist characterizing species in the Urocleidoides genus. Some DNA sequences have been efficacious in systematic studies and in the reconstruction of phylogenies of fish parasites. Relevant roles have been given to the sequence of the mitochondrial gene of cytochrome c oxidase I (COI). This study characterized COI sequences of the parasites Urocleidoides malabaricusi and U. cuiabai in trahira fish Hoplias aff. malabaricus of the flood plain of the Upper River Paraná, Brazil. The two species under analysis were distinguished by sequencing and analysing a 420-bp fragment of the COI gene, which suggested the existence of the cryptic species U. malabaricusi.

<p>Thrips are widely reported as pests in vegetable crops. However, the existence of Phlaeothripidae members has a less concern in Indonesia. Phlaeothripidae is the only family of  Tubulifera Suborder and some reports suggested that they had potential to be pests in several crops due to their ability to roll up and to make galls on leaves. The first step in pest management attempt is to identify the pest accurately and quickly, so the pest management can be on target and more efficient. One of the identification methods is the molecular identification using DNA barcoding techniques. This study aimed to characterize and to compare species thrips in banyan, nutmeg, and marine seruni based on their molecular characteristics. This research was conducted in Bogor and Kuningan. The process of molecular characterization consisteds of four steps  DNA total extraction, amplification by using PCR, COI gene sequence, and data analysis.  PCR programme was succesfully to amplified mt<em>COI</em> gene fragment at 710 bp. The length of mt<em>COI </em>gene of <em>Gynaikothrips uzeli, Haplothrips ganglbaueri</em>, and <em>Pseudophilothrips ichini</em> were 704, 686, and 702 bp dominated by A and T bases with nucleotide variation value of 27.8%. This results confirmed that molecular characterization using mt<em>COI </em>gene mitochondrial had successfully supported the morphological data. </p><p><strong>How to Cite</strong></p><p>Kurniawaty, N., Hidayat, P. &amp; Rauf, A.
