Abstract Digenea Carus, 1863 represent a highly diverse group of parasitic platyhelminths that infect all major vertebrate groups as definitive hosts. Morphology is the cornerstone digenean systematics, but molecular markers have been instrumental in searching for stable classification system subclass and establishing more accurate species limits. The first comprehensive phylogenetic tree published 2003 used two nuclear rRNA genes (ssrDNA = 18S rDNA lsrDNA 28S rDNA) was based on 163 taxa...
We describe a new species of Auriculostoma Scholz, Aguirre-Macedo & Choudhury, 2004 based on several sources information including morphology (light and scanning electron microscopy [SEM]), sequences two nuclear genes, host association, geographical distribution. Morphologically, the most closely resembles astyanace 2004, but differs by having deeply lobated testes cirrus-sac extending posteriorly to seminal receptacle level. lobata n. sp. can be readily distinguished from all other...
We assessed metrics of the metazoan parasite infracommunities dusky flounder (Syacium papillosum) as indicators aquatic environmental health Yucatan Shelf (YS) prior to oil extraction. sampled and its parasites along YS, mostly during 2015 north wind season (November–April). Our aims were: (i) determine whether infracommunity S. papillosum exhibit significant differences among YS subregions; (ii) probability occurrence species individuals were affected by variables, nutrients, heavy metals...
The phylogenetic relationships within Neodermata were examined based on putative orthologous groups of proteins (OGPs) from 11 species Monogenea, Trematoda, and Cestoda. dataset included OGPs BUSCO OMA. Additionally, peptidases identified evaluated as markers. Phylogenies inferred using the maximum likelihood method. A network analysis a hierarchical grouping principal components (HCPC) performed. analyses showed monopisthocotylean monogeneans sister-group cestodes, polyopisthocotylean...
Abstract Trematodes of the family Allocreadiidae are primarily found in intestines freshwater fishes around world. The includes 15 genera and c. 130 species. last 2 decades have witnessed an increase genetic library its Molecular data been crucial for species delimitation description within understanding their evolutionary biogeographical history classification. Here, mitogenomes 3 allocreadiids were obtained using high throughput sequencing methods. Mitogenomes compared with other members...
Dogs can discriminate between people infected with SARS-CoV-2 from those uninfected, although their results vary depending on the settings in which they are exposed to individuals or samples of urine, sweat saliva. This variability likely depends viral load people, may be closely associated physiological changes patients. Determining this is challenging, and a practical approach use cycle threshold (Ct) value RT-qPCR test. The hypothesis was that dogs should have specific Ct range at could...
Abstract The family Clinostomidae Lühe, 1901 contains 29 species allocated to seven genera, of which Clinostomum Leidy, 1856 is the most diverse, with c. 14 valid species. diversity has been assessed, combining morphological and molecular data. genetic library for in this genus increased steadily, although there little or no information other genera included family. Molecular phylogenetic relationships among clinostomids have not their classification still based on traits. monotypic...
<i>Astyanax mexicanus</i> has repeatedly colonized cave environments, displaying evolutionary parallelisms in many troglobitic traits. Despite being a model system for the study of adaptation to life perpetual darkness, parasites that infect cavefish are practically unknown. In this study, we investigated macroparasite communities 18 populations from independent lineages and compared them with parasite diversity found their sister surface fish populations, aim better understanding role play...
Abstract Helminth species of Neotropical bats are poorly known. In Mexico, few studies have been conducted on helminths bats, especially in regions such as the Yucatan Peninsula where Chiroptera is mammalian order with greatest number species. this study, we characterized morphologically and molecularly helminth explored their infection levels parasite–host interactions Peninsula, Mexico. One hundred sixty-three (representing 21 species) were captured between 2017 2022 15 sites throughout...
In this survey, we inventoried the helminths of heteromyid and cricetid rodents captured in Yucatan Peninsula from 2017 to 2019. Helminths were identified using morphological techniques (clearing, staining, scanning electron microscopy). Also, 28S rRNA gene individuals several helminth taxa was successfully amplified sequenced. To confirm identification at generic level, some cases specific genealogical relationships parasites, phylogenetic analyses performed with new sequences. We 22...
Abstract Species of the allocreadiid genus Creptotrema are parasites freshwater fishes in Americas. possess one pair muscular oral lobes on sucker. Currently, contains eight species, six distributed South America, Middle America and North America. Genetic data only available for American funduli , a parasite fundulids originally described from Oneida Lake, New York State. In this study, we obtained 28S ribosomal DNA sequences trematodes morphologically similar to agonostomi mountain mullet,...
Abstract To date, 23 species of trematodes have been reported in bats from Mexico. However, some regions Mexico, such as the Yucatan Peninsula, many do not helminthological records. Here, we sampled four localities Southeastern Mexico April 2017 to February 2022. Parasites were collected intestine bats: Pteronotus fulvus , Eumops nanus Noctilio leporinus and Nyctinomops laticaudatus . Conventional morphological techniques molecular tools with 28S ribosomal gene used describe helminths. We...
In the present study, helminths from six Didelphis virginiana and one Philander vossi are reported using morphological techniques (clearing, staining, scanning electron microscopy). Additionally, 28S rRNA sequences of individuals nine helminth taxa provided. Phylogenetic analyses were performed with new to confirm identification genealogical relationships parasites. Thirteen identified, comprising trematodes Brachylaima sp. Platynosomum illiciens, cestode Mathevotaenia sp., nematodes Cruzia...
Abstract Honey production in Mexico is an ancient economic, social, and biocultural activity for indigenous communities, Mayas, Totonacs, among others. Stingless bee honeys are used traditional medicine to treat gastrointestinal, respiratory, dermatological, ophthalmic ailments as they contain compounds with antioxidant, antibacterial, anti-inflammatory, antifungal activities. Here, a comprehensive physicochemical characterization of Mexican stingless presented contribution strengthening the...
In order to establish the helminthological record of viviparous fish species Zoogoneticus purhepechus,72 individuals were collected from 2 localities, La Luz spring (n= 45) and Los Negritos 27), both in thelower Lerma River, Michoacán state, Mexico. Twelve helminth taxa recovered, 5 adults (the digeneansMargotrema bravoae Phyllodistomum sp., cestode Bothriocephalus acheilognathi, nematode Rhabdochonalichtenfelsi acanthocephalan Pomphorhynchus cf. bulbocolli), 7 larvae metacercariae...
The freshwater fish digenean Pseudosellacotyla lutzi ( Freitas, 1941 ) Yamaguti, 1954 has had an unsettled taxonomic history, and at various times been classified as a member of Nanophyetidae, Heterophyidae, Microphallidae, Faustulidae, Cryptogonimidae. Nine individual specimens the trahira, Hoplias malabaricus (Bloch, 1794), were sampled in Paraná River basin, State, Brazil; 22 P. collected. One specimen was used to obtain sequence domains D1-D3 28S rRNA gene, perform phylogenetic analysis...
Eight species of helminths are reported from the intestine 52 white ibis [(Eudocimus albus (Linneaeus)] collected in 14 localities along Mexican coasts Gulf Mexico, and Pacific Ocean. Three trematodes, Parastrigea cincta Brandes, 1888; diovadena Dubois & Macko, 1972, Patagifer lamothei Dronen Blend, 2008, one cestode Cyclustera ibisae Schmidt Bush, 1972 four acanthocephalan Hexaglandula corynosoma Travassos, 1915, Arhythmorhynchus frassoni Molin, 1858, Southwellina hispida Van Cleave,...
