Box 27, Monkey Bay, Malawi 2 Department of Environmental Solution Technology, Ryukoku University, Seta-Oe, Otsu, 520-2194 Shiga, Japan 3 Department of Biology, Chancellor College, University of Malawi, P.O. Box 280, Zomba, Malawi Abstract Fish parasites have diverse ecological impacts on fish populations and are presently becoming useful as bio-indicators of fish migration and feeding. Studies of fish parasite in Lake Malawi severely lag behind the strides made in eco-evolutionary studies of its ichthyofauna. Over a period of eleven months from April 2003, we examined more than 1300 Engraulicypris sardella from Lake Malawi for cestode parasites. About 54 % of the fish had infections of between one and eight Ligula intestinalis plerocercoids. The infection occurred throughout the study period (mean prevalence 59 ±13%) but was most prevalent in December and June and was least prevalent in April. The majority of the hosts (78%) had a light parasite burden (one or two). Parasite prevalence increased with age of the fish. Prevalence and infection intensity oscillated closely with periods of peak abundance of zooplankton, the main food of E. sardella and intermediate hosts (copepods) of L. intestinalis. Increased exposure to the parasite with age aggravated by an ontogenetic diet shift from phytoplanktivory to zooplanktivory may be interacting with fluctuations in zooplankton production in driving the trophic transmission patterns of L. -

The carcasses of fish with ligulid larvae were first found in the river-edge areas of Chilgok-bo in Nakdong-gang (River), Korea at early February 2016. This ecological phe- nomena also occurred in the adjacent areas of 3 dams of Nakdong-gang, i.e., Gangjeong-bo, Dalseong-bo, and Hap- cheon-Changnyeong-bo. Total 1,173 fish carcasses were collected from the 4 regions. To examine the cause of death, we captured 10 wondering carp in the river-edge areas of Hapcheon-Changnyeong-bo with a landing net. They were 24.0-28.5 cm in length and 147-257 g in weight, and had 2-11 plerocercoid larvae in the abdominal cavity. Their digestive organs were slender and empty, and reproductive organs were not observed at all. -

Received: 18 August 2020; Accepted: 27 September 2020; Published: 3 October 2020 Abstract: Foodborne parasitoses compared with bacterial and viral-caused diseases seem to be neglected, and their unrecognition is a serious issue. Parasitic diseases transmitted by food are currently becoming more common. Constantly changing eating habits, new culinary trends, and easier access to food make foodborne parasites’ transmission effortless, and the increase in the diagnosis of foodborne parasitic diseases in noted worldwide. This work presents the applications of numerous proteomic methods into the studies on foodborne parasites and their possible use in targeted diagnostics. Potential directions for the future are also provided. Keywords: foodborne parasite; food; proteomics; biomarker; liquid chromatography-tandem mass spectrometry (LC-MS/MS) 1. Introduction Foodborne parasites (FBPs) are becoming recognized as serious pathogens that are considered neglect in relation to bacteria and viruses that can be transmitted by food [1]. The mode of infection is usually by eating the host of the parasite as human food. Many of these organisms are spread through food products like uncooked fish and mollusks; raw meat; raw vegetables or fresh water plants contaminated with human or animal excrement. -
Zoonotic Helminths Affecting the Human Eye Domenico Otranto1* and Mark L Eberhard2
Otranto and Eberhard Parasites & Vectors 2011, 4:41 http://www.parasitesandvectors.com/content/4/1/41 REVIEW Open Access Zoonotic helminths affecting the human eye Domenico Otranto1* and Mark L Eberhard2 Abstract Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

Life Cycle and Larval Forms in Cestodes
GENERAL LIFE CYCLE AND LARVAL FORMS IN CESTODES Generally, cestode life cycles are not as complicated as those of digeneans because they usually do not involve asexually reproductive larval phases. However, most tapeworms also require at least one or two intermediate hosts. Life cycle patterns among the eucestoda are of considerable phylogenetic importance, for they often indicate the membership of particular species in specific orders. Unfortunately, the complete representative developmental patterns of all tapeworm orders are as yet not known. The patterns , some yet incomplete, for the Trypanorhyncha, Tetraphyllidea, Proteocephala, Cyclophyllidea, and Pseudophyllidea, however, are known. Trypanorhynchan life cycle pattern: No complete life cycle is known among the Trypanorhyncha. However, the following pattern, based on the life cycle of Lacistorhynchus tenuis as reported by Riser (1956), gives some indication of how this group develops. Adult Lacistorhynchus tenuis lives in the intestinal spiral valve of sharks. Eggs discharged by the adult tapeworms pass into the sea water and a ciliated larva ,the coracidium , hatches from each egg. The coracidia are ingested by the splash-pool copepod Tigriopus fulvus. The larval stage within the haemocoel of this crustacean is the tailess procercoid. When experimentally fed to fish, the procercoid did not undergo further development, and therefore, the complete life cycle is not known. Tetraphyllidean life cycle pattern: Very little information is available on the life cycles of Tetraphyllideans. Reichenbach-Klinke (1956), has reported that in case of Acanthobothrium coronatum, a parasite of elasmobranchus , developing procercoids occur in small crustaceans, and the next larval stage, plerocercoids occurs in sardines. When the latter are fed to sharks, adult cestodes develop from them. -
Plerocercoid of Ligula Intestinalis (Cestoda: Pseudophyllidea)

Jpn., 72(5): 277-284, December, 1995 Immunocytochemical Evidence for the Presence of Prolactin in the Plerocercoid of Ligula Intestinalis (Cestoda: Pseudophyllidea) By Bo LIU, Hidekazu WAKURI and Ken-ichiro MUTOH Department of Animal Anatomy, Changchun University of Agriculture and Animal Sciences, Xian Road 175, Changchun, Jilin 130062, P.R. China Department of Veterinary Anatomy, School of Veterinary Medicine and Animal Sciences, Kitasato University, Towada, Aomori 034, Japan -Received for Publication, November 9,1995- Key Words: Prolactin, Plerocercoid, Cestode, Nervous system, Immunocytochemistry Summary: Immunoreactivity to prolactin in the nervous system of the plerocercoid of Ligula intestinalis was demonstrated by immunocytochemical method. Numerous PRL immunoreactive perikarya with long varicose fibres were observed in the peripheral nervous system in the worm, mainly in the transversal muscle layer and medullary parenchyma of the midbody. A few fibres were found in the main nerve cords of the central nervous system. PRL positive neurons sent their processes to associate with the main nerve cords. The immunostaining terminals appeared in the subtegument region in the lateral border of the plerocercoid. The result indicates that PRL immunoreactivity is well-developed in the plerocercoid of the cestode. The significance of the localization of prolactin in the worm is discussed. Recent 'years a interest in the neuropeptides in immunoreactivity in the Hymenolepis nana using the platyhelminthes is growing. There are no true human prolactin antibody has been reported endocrine glands and a circulatory system in these (Kumazawa & Moriki, 1986). organisms, and so the neurosecretory (peptidergic) The aim of the present study was to explore the component of the nervous system probably serves an prolactin immunocytochemicalevidence for the pre- important role in the flatworm.
