REVIEW
Zoe C Groom, Aristotle D Protopapas, Vasileios Zochios
Cardiovascular diseases are widely distributed throughout the world. Human parasitic infections are ubiquitous. Tropical parasites are increasingly recognized as causes of cardiovascular diseases. In this review, we address the most frequently reported parasites that directly infect the myocardium, including Trypanosoma cruzi, the protozoal causative agent of American trypanosomiasis (Chagas disease), and Taenia solium, the cestode causative agent of taeniasis and cysticercosis. We also discuss tropical endomyocardial fibrosis, trichinellosis and schistosomiasis...

Khawia sinensis is an important species in freshwater fish causing considerable economic losses to the breeding industry. This is the first mt genome of a caryophyllidean cestode characterised. The entire mt genome of K. sinensis is 13,759 bp in length. This mt genome contains 12 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and two non-coding regions. The arrangement of the K. sinensis mt genome is the same as other tapeworms, however, the incomplete stop codon (A) is more frequent that other species...

A comprehensive literature review shows that 12 types of pathogens, micropredators and parasites are reported to interact with chaetognaths, mostly digenean trematodes, cestodes and nematodes larval stages. Through analysis of 78,152 chaetognaths from a monthly zooplankton time series (Jan 1996-Dec 1998) collected in the Mexican Central Pacific twelve acanthocephalan larvae parasitizing chaetognaths were discovered. This is the first record of an acanthocephalan parasitizing chaetognaths, raising to 13 the types of symbionts known to interact with them (excluding predators)...

Parasites are one of the most serious limiting factors in aquaculture. The Electric catfish Malapterurus electricus was subjected to study the prevalence and mean intensity of parasitic infections throughout the whole year of 2015. Heavy metals accumulation in host fish and parasites were determined in relation to water quality and sediments of two different sites of Lake Manzala (Manzala and Bahr El-Baqar), Egypt. A total of 100 specimens of Electric catfish were collected and examined for the presence of helminth parasites...

Bats are recognized as potential hosts of pathogens exploiting the food chain to reach them as definitive hosts. However, very little is known about their endoparasites, especially for Neotropical bats. In this study, we assessed the helminth fauna associated with 3 insectivorous bat species roosting in the same single hot cave in central Veracruz, Mexico: the ghost-faced bat (Mormoops megalophylla), the naked-backed bat (Pteronotus davyi) and Wagner's mustached bat (Pteronotus personatus). During a period of 1 yr (April 2007-2008), a total of 135 mormoopid bats were collected and examined for helminths...

Anthelmintic drugs require effective concentrations to be attained at the site of parasite location for a certain period to assure their efficacy. The processes of absorption, distribution, metabolism and excretion (pharmacokinetic phase) directly influence drug concentrations attained at the site of action and the resultant pharmacological effect. The aim of the current review article was to provide an overview of the relationship between the pharmacokinetic features of different anthelmintic drugs, their availability in host tissues, accumulation within target helminths and resulting therapeutic efficacy...

Human cystic echinococcosis, an endemic zoonosis in Algeria, is caused by larvae of the cestode Echinococcus granulosus. Parasitic modulation of the immune response allows E. granulosus to persist in intermediate hosts. Previous in vitro and in vivo immunological studies have shown differences in host immune responses according to the status and location of the hydatid cysts in the body. In this study, a proteomic analysis of human hydatid fluids was performed to identify the proteins in hydatid cyst fluids...

Niclosamide, an anthelmintic drug approved by the US Food and Drug Administration against cestodes, is used to treat tapeworm infection. In this study, we show that niclosamide can potentially inhibit signal transducer and activator of transcription 3 (STAT3) in colon cancer cell lines. Combined inhibition of epidermal growth factor receptor and STAT3 by erlotinib and niclosamide synergistically induces apoptosis and antiproliferation in colon cancer cell lines. Our findings suggest that erlotinib and niclosamide combination provides an effective therapeutic approach to improving the prognosis of colon cancer...

Much progress has recently been made towards revising the taxonomic assignments of genera originally classified in the polyphyletic "Tetraphyllidea". Many of these genera, including Echeneibothrium van Beneden, 1850, were accommodated in the order Rhinebothriidea. However, beyond this larger taxonomic action, little work has been conducted on this genus over the last 50 yrs. As a consequence, the criteria employed for characterizing species of Echeneibothrium have lagged behind those typically employed in more modern descriptions of elasmobranch-hosted cestode taxa...

Neem (Azadirachta indica), has been known to be a curative for various ailments and diseases in the traditional Indian medicinal system from times immemorial. A glycolipid sulfonoquinovosyldiacylglyceride (SQDG) isolated from the leaves of neem has been found to be a proactive antibacterial and antiviral agent in previous studies. The current communication pertains to the anthelmintic activity of SQDG in vitro against a model cestode Raillietina spp. The results of efficacy tests showed a paralysis time of 1...

Taenia ovis is a tapeworm that is mainly transmitted between dogs and sheep or goats and has an adverse effect on sheep industry. miRNAs are short regulatory non-coding RNAs, involved in parasite development and growth as well as parasite infection. The miRNA profile of T. ovis remains to be established. Herein, 33 known miRNAs belonging to 23 different families were identified in T. ovis metacestodes using deep sequencing approach. Of them, expression of some miRNAs such as tov-miR-10 and -let-7 was absolutely predominant...

This review analyses the scarce available data on biodiversity and transmission of helminths in Arctic coastal ecosystems and the potential impact of climate changes on them. The focus is on the helminths of seabirds, dominant parasites in coastal ecosystems. Their fauna in the Arctic is depauperate because of the lack of suitable intermediate hosts and unfavourable conditions for species with free-living larvae. An increasing proportion of crustaceans in the diet of Arctic seabirds would result in a higher infection intensity of cestodes and acanthocephalans, and may also promote the infection of seabirds with non-specific helminths...
