“…The studies by Dung (20), Mowlavi (7) and the current study found two species of Lymnaea. Researchers such as Mowlavi and Mansoorian (6, 7), Dung (20), Barkia (4), Afshan (3), Kebapci (19) and the current study authors showed one species of Melanoides, while the study by Ektefa (8) showed two species of this genus. In addition, Mowlavi (7), Mansoorian (22) and Kebapci (19) found a species of Melanopsis in their studies, while Ektefa identified five species (8).…”

“…The reason for difference in the detected snail genera in sampling sites and with other literature was not determined, which may be due to various physicochemical factors such as temperature, hardness, pH, seasonal changes, topography, chemical composition, vegetation, pollution and the size of water bodies (1,3). Researchers such as Barkia in Morocco (4), Afshan in Pakistan (3), Kebapci in Turkey (19), Kucharz in Poland (11), Dung in Vietnam (20), El-Kady in Egypt (21) conducted surveys on fresh water snails in recent years. In Iran, studies by Mansoorian (6), Mowlavi (7) and Ektefa (8) in Khuzestan province are examples of such studies.…”

Background: Some freshwater snails are acting as intermediate hosts for digenetic trematodes. Studies on distribution of freshwater snails are important to determine the transmission patterns of the trematoda. Objectives: The current study aimed to identify medically important snails of Miangran Lake in Izeh, Khuzestan province, Iran. Materials and Methods: Sampling was conducted in fourteen sites around Miangran Lake in 2014. The collected samples were placed in plastic containers containing 70% ethyl alcohol, prior to consideration. The identification was carried out according to shell characteristics. Data were analyzed descriptively. Results: All sampling sites were positive for medically important snails. Overall, nine genera and thirteen species were identified. The most diversity in genus was found in Melanopsis. Five genera of snails detected in the study with known medical importance include: Bithynia spp., Bulinus spp., Lymnaea spp., Melanoides spp. and Melanopsis spp. Melanoides spp. was observed in thirteen and Bellamya spp. was identified in two sites. Also, in this study Melanoides spp., Bulinus spp., and Lymnaea spp. were widespread snails around Miangran Lake. Conclusions: The reason for difference in the detected snail genera in sampling sites may be due to various physicochemical factors. According to the current study, medically important snails exist in Miangran Lake and they could be a source of trematode infections for the local people. Controlling measures after comprehensive studies should be applied.

“…Manure from the husbandry is used to fertilize ponds, so as to stimulate algal growth and subsequently fish growth, and remnants from garden products and fish remains can be fed to dogs, cats or pigs. Mud from fish ponds is used to fertilize gardens or fields (Dung et al 2010). The recirculation of waste material including human and animal manure is conducive for the life cycle of FZT.…”

Most of the second intermediate hosts of FZT species are freshwater fish, except for some cases where estuary fish (mullet) or marine fish (salmon) are hosts.…”

Fishborne zoonotic trematodes (FZT), infecting humans and mammals worldwide, are reviewed and options for control discussed. Fifty nine species belonging to 4 families, i.e. Opisthorchiidae (12 species), Echinostomatidae (10 species), Heterophyidae (36 species) and Nanophyetidae (1 species) are listed. Some trematodes, which are highly pathogenic for humans such as Clonorchis sinensis, Opisthorchis viverrini, O. felineus are discussed in detail, i.e. infection status in humans in endemic areas, clinical aspects, symptoms and pathology of disease caused by these flukes. Other liver fluke species of the Opisthorchiidae are briefly mentioned with information about their infection rate and geographical distribution. Intestinal flukes are reviewed at the family level. We also present information on the first and second intermediate hosts as well as on reservoir hosts and on habits of human eating raw or undercooked fish.

Lantana camara Essential Oils from Vietnam: Chemical Composition, Molluscicidal, and Mosquito Larvicidal Activity

Lantana camara is a troublesome invasive plant introduced to many tropical regions, including Southeast Asia. However, the plant does hold promise as a source of essential oils that may be explored for potential use. Fresh water snails such as Pomacea canaliculata, Gyraulus convexiusculus, and Tarebia granifera can be problematic agricultural pests as well as hosts for parasitic worms. Aedes and Culex mosquitoes are notorious vectors of numerous viral pathogens. Control of these vectors is of utmost importance. In this work, the essential oil compositions, molluscicidal, and mosquito larvicidal activities of four collections of L. camara from north‐central Vietnam have been investigated. The sesquiterpene‐rich L. camara essential oils showed wide variation in their compositions, not only compared to essential oils from other geographical locations (at least six possible chemotypes), but also between the four samples from Vietnam. L. camara essential oils showed molluscicidal activities comparable to the positive control, tea saponin, as well as other botanical agents. The median lethal concentrations (LC50) against the snails were 23.6–40.2 μg/mL (P. canaliculata), 7.9–29.6 μg/mL (G. convexiusculus), and 15.0–29.6 μg/mL (T. granifera). The essential oils showed good mosquito larvicidal activities with 24‐h LC50 values of 15.1–29.0 μg/mL, 26.4–53.8 μg/mL, and 20.8–59.3 μg/mL against Ae. aegypti, Ae. albopictus, and Cx. quinquefasciatus, respectively. The essential oils were more toxic to snails and mosquito larvae than they were to the non‐target water bug, Diplonychus rusticus (24‐h LC50=103.7–162.5 μg/mL). Sesquiterpene components of the essential oils may be acting as acetylcholinesterase (AChE) inhibitors. These results suggest that the invasive plant, L. camara, may be a renewable botanical pesticidal agent.
