Abstract
Neotropical fish amphistomes represent a highly diverse group within the Paramphistomoidea, with wide distribution across major South American hydrological drainages. However, the limited molecular characterization of these taxa has impeded a comprehensive assessment of their evolutionary relationships and the systematic relevance of morphological features in classification schemes. Our study, based on the critical evaluation of the type material of both nominal species of Zonocotyle (type genus of the monotypic Zonocotylidae), and newly collected specimens of Zonocotyle bicaecata from Steindachnerina insculpta (Curimatidae) in the Upper Paraná River basin, Brazil, presents a morphological reappraisal of Z. bicaecata and provides molecular data (28S rDNA, ITS1-5.8S-ITS2 region, and COI mtDNA) to assess its phylogenetic relationships. Our phylogenetic analyses confirm this species belongs to the Paramphistomoidea. The most comprehensive analyses (based on 28S and COI) further indicate a close relationship with other fish amphistomes from the Neotropical region. Additionally, we emphasized the necessity for a new classification within Paramphistomoidea and briefly discussed the host range of Zonocotyle among curimatid fish hosts.

Abstract
Rumen fluke is a parasitosis that infects ruminant animals across a wide geographical range of countries. It is a severe infection in temperate and tropical climate regions of Asia, Australia, Africa, and Europe, which cause significant economic losses. In this review, the available information to date on rumen fluke species infecting cattle and buffaloes in Asian countries is evaluated. The citation search was performed through specific keywords, literature published from 1964 to 2021, retrieved from electronic databases: Scopus, Web of Science, Pub Med, Education Resources Information Center (ERIC), Science Direct, Elsevier, and Google Scholar. Twenty-six (26) rumen fluke species belonging to two families: Paramphistomidae 61.5% (16/26) and Gastrothylacidae 38.4% (10/26), were reported in cattle and buffaloes in fourteen Asian countries. Paramphistomum cervi and Cotylophoron cotylophorum are the most prevalent species with broader distribution in countries than the other genera. The coprological prevalence varies from 0.8% to 98.17% and 0.86% to 78.4% in cattle and buffaloes, respectively. The prevalence of rumen fluke by fluke counts method range between 6.45% to 90.6% and 4.29% to 75.07% in cattle and buffaloes, respectively. The sedimentation method and fluke count are reliable tests for detecting rumen fluke in live and slaughtered animals. In conclusion, the rumen fluke should be considered a critical production disease that affects cattle and buffaloes in Asia. Further studies are necessary to determine the rumen fluke-snail associations, develop diagnostic tests to detect prepatent infections in the definitive host, determine the economic importance of rumen fluke, and determine the efficacy of different anthelmintic in the treatment of patent infections in the definitive host.

Abstract
Zygocotyle lunata inhabits the caecum of birds and mammals from the American continent. This amphistome parasite is easily maintained in the laboratory and serves as a model organism in life-cycle studies, but it has seldom been studied using molecular data. Neither the position of Z. lunata in the superfamily Paramphistomoidea nor the monophyly of the Zygocotylidae has been evaluated with molecular phylogenetic methods. In the present study, adult specimens of Z. lunata obtained experimentally in mice from Brazil were submitted to molecular studies. Partial sequences of nuclear (1261 bp of 28S and 418 bp of 5.8S-ITS-2) and mitochondrial (1410 bp of cytochrome c oxidase 1, cox1) markers were compared with published data. In the most well-resolved phylogeny, based on 28S sequences, Z. lunata clustered in a well-supported clade with Wardius zibethicus, the only other species currently included in the Zygocotylidae, thus confirming the validity of this family. Divergence of 28S sequences between these species was 2.2%, which falls in the range of intergeneric variation (0.9-5.6%) observed in the other two monophyletic groups in the 28S tree, i.e., representatives of Gastrodicidae and Neotropical cladorchiids (Cladorchiidae). Analysis of ITS-2 and two parts of the cox1 gene placed Z. lunata within poorly resolved clades or large polytomies composed of several paramphistomoid families, without clarifying higher-level phylogenetic relationships. The cox1 of a Brazilian isolate of Z. lunata is 99.6% similar to a Canadian isolate, confirming the pan-American distribution of the species. Finally, our phylogenetic reconstructions of Paramphistomoidea revealed a complex scenario in the taxonomic composition of some amphistome families, which highlights a need for further integrative studies that will likely result in rearrangements of traditional morphology-based classifications.

Molecular classification of rumen fluke eggs in fecal specimens from Suphanburi Province, Thailand, based on cytochrome C oxidase subunit 1. VETERINARY PARASITOLOGY- REGIONAL STUDIES AND REPORTS 2020; 20:100382.

Abstract
Rumen fluke infections have been known to cause paramphistomiasis in both wild and domestic animals worldwide. Occasionally, coinfections of rumen flukes (Carmyerius, Fischoederius, and Paramphistomum) with liver flukes (Fasciola) have been observed due to the similar life cycles that these two species share. This study involved an alternative approach that was developed to classify and distinguish rumen fluke eggs from other genera by using the polymerase chain reaction (PCR) method based on cytochrome c oxidase subunit 1 (COI). Thirty-eight fecal specimens of Bos taurus from Suphanburi Province, Central Thailand were examined using the formalin-ether sedimentation technique. PCR detection was then performed using COI-specific primers that were developed in this study. The results showed that this primer set can classify and distinguish the egg specimens into a separate clade of the genera comprising Gastrothylax, Carmyerius, Fischoederius, Paramphistomum, Explanatum, and Fasciola. Moreover, epidemiological mapping revealed coinfections of three genera of rumen flukes at some collection sites, leading to the need to further investigate Paramphistomoidea infection along with Fasciolidae infection within the endemic area. This data is important for monitoring the outbreak of these parasites in Suphanburi Province, Thailand. It can be applied for initiating surveillance programs of paramphistomiasis and fascioliasis in veterinary studies.

Abstract
M esostephanus appendiculatus (Family: Cyathocotylidae) is one of the unique trematodes that complete their cycles in human and animal intestines in many countries of the world. The main source of its transmission is eating raw or undercooked infected fish muscle. Earliest analyses of genes to different parasites supported the analysis of helminthes either biological or morphological. This paper detected M. appendiculatus sequence with GenBank accession number gb (KY026782). Comparison of M. appendiculatus with other helminthes using BioEdit 7 and MEGA7 program shows some similarity in different points along its sequence. The phylogenetic analysis clarifies that it was closely related to both trematodes (Clinostomum complanatum and Echinochasmus japonicus) and some cestodes of fish origin such as Polyonchobothrium polypteri, Bothriocephalus sp., and Haplobothrium globuliforme. The obtained results provide a good source for genome analysis of M. appendiculatus in relation to other Platyhelminthes.

Abstract
The aim of this study was to analyze the phylogenetic relationship between
Explanatum explanatum populations in India and other countries of the
Indian subcontinent. Seventy liver amphistomes collected from four localities in India
were identified as E. explanatum based on the nucleotide sequences of
ribosomal ITS2. The flukes were then analyzed phylogenetically based on the nucleotide
sequence of the mitochondrial gene nad1 in comparison with flukes from
Bangladesh and Nepal. In the resulting phylogenetic tree, the nad1
haplotypes from India were divided into four clades, and the flukes showing the haplotypes
of clades A and C were predominant in India. The haplotypes of the clades A and C have
also been detected in Bangladesh and Nepal, and therefore, it seems they occur commonly
throughout the Indian subcontinent. The results of AMOVA suggested that gene flow was
likely to occur between E. explanatum populations in these countries.
These countries are geographically close and have been historically and culturally
connected to each other, and therefore, the movements of host ruminants among these
countries might have been involved in the migration of the flukes and their gene flow.
