Introduction: Intestinalparasite infections still are very common in tropical country such as Vietnam. Therefore evaluation of the prevalence of them should be done. Materials and methods: A crosssectional descriptivestudy were carried out to use the wet mount direct examination, Kato and ELISA technique for evaluation the rate of intestinal parasite infections, interviewed them to reveal their life’s hygenic condition, knowledge and risk behaviour of intestinal parasite infections in 640 patients attending to the in Hue University of hospital. Result: The rate of soiltransmitted intestinal helminth were lower than the foodborne infection of cestode and trematode such as: Taenia solium/saginata 3.64%, Clonorchis sinensis 2.73%. The rate of positive antibody of rare intestinal parasite were Fasciola gigantica 40.68%, E. histolytica/dispar 43.75%, Toxocara canis 32.43%, Gnasthostoma spinigerum 37.5%, Taenia solium 51.43%, Strongyloidesstercoralis 16.67%. Most of people has hygenic life condition with hygenic water available. The popular knowledge of intestinal parasite diseases of transmission, pathology, prevention and treatment were concentrate on oiltransmittedintestinal helminth.There were high rate of platyhelminths infectious behaviourssuch as: eating raw water plant 75.6%, eating raw beef 80.6%, eating raw pork 72.2%, eating raw fish 11.8%, bare foot 34.2%. Conclusions: The result of our study showed that the higher rate of foodborne cestode and trematode than soiltransmittedhelminth correspond tothe hygenic life condition, the knowledge of the diseases and risk behavior of intestinal parasites infection.

Abstract Background Neurocysticercosis caused by Taenia solium when the parasite lodges in the central nervous system, is an important cause of human seizures and mortality in sub-Saharan Africa. The parasite is prevalent in many regions of Uganda. Pigs are intermediate hosts for T. solium, and we evaluated a T. solium control program in pigs, involving vaccination of pigs with the TSOL18 vaccine and treatment with oxfendazole. Methods The study was conducted in two districts of Eastern Uganda involving the rural village communities of Bukedea (intervention area) and Kumi (control area) during 2016–2017. Seven hundred and thirty-four households were enrolled in the study. Pigs in the intervention area received intramuscular immunizations with TSOL18 (Cysvax™) and an oral medication with 30 mg/kg oxfendazole (Paranthic™) at approximately 3-monthly intervals for 18 months. Porcine cysticercosis was evaluated by post-mortem examination. At the beginning of the study, 111 pigs were examined. In an interim evaluation in the intervention area, 55 pigs were evaluated 12 months after starting the project. At the end of the study approximately 3 months after the final intervention, 55 pigs from the intervention area and 56 pigs from the control area were evaluated. Results The prevalence of porcine cysticercosis for the two sites was 16.2% at the beginning of the study (17.2% in the intervention area and 15.1% in the control area) with no statistically significant difference (P = 0.759) between the two study sites. Among the 110 animals assessed from the intervention site (55 at the interim evaluation and 55 at the final evaluation), no pig with viable T. solium cysts was found. There was a statistically significant difference between the prevalence at baseline (17.2%) and at the end of the study (0%) in the intervention area (P = 0.001) and a statistically significant difference between the intervention (0%) and control areas (5.4%) (P = 0.041) at the end of the study. Conclusions Three-monthly concurrent vaccination of pigs with the TSOL18 vaccine and medication with oxfendazole eliminated T. solium transmission by the animals involved in the study. Application of vaccination with medication in pigs has the potential to reduce transmission of T. solium in Uganda and other endemic countries.

Cysticercosis is an infection with larval cysts of the cestodeTaenia solium. Through pathways that are incompletely understood, dying parasites initiate a granulomatous reaction that, in the brain, causes seizures. Substance P (SP), a neuropeptide involved in pain-transmission, contributes to inflammation and previously was detected in granulomas associated with deadT. crassicepscysts. To determine if SP contributes to granuloma formation, we measured granuloma-size and levels of IL-1β, TNF-α, and IL-6 within granulomas inT. crassiceps-infected wild type (WT) mice and mice deficient in SP-precursor (SPP) or the SP-receptor (neurokinin 1, NK1). Granuloma volumes of infected SPP- and NK1-knockout mice were reduced by 31 and 36%, respectively, compared to WT mice (P<.05for both) and produced up to 5-fold less IL-1β, TNF-α, and IL-6 protein. Thus, SP signaling contributes to granuloma development and proinflammatory cytokine production inT. crassicepsinfection and suggests a potential role for this mediator in human cystercercosis.
