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...
Fish susceptibility to parasitic infection is a crucial issue in aquaculture, where the density of captive fish increases intensity infections. Monogeneans are group flatworms that include pathogenic species for fish, among them Neobenedenia spp., which pose significant challenges health farming systems. Understanding dynamics parasitism and how they may vary according host or environmental conditions essential development effective management strategies aquaculture. Therefore, aim this...
Genomic resources for Platyhelminthes of the class Monogenea are scarce, despite diversity these parasites, some species which highly pathogenic to their fish hosts. This work aimed generate de novo-assembled transcriptomes two monogenean species, Scutogyrus longicornis (Dactylogyridae) and Rhabdosynochus viridisi (Diplectanidae), providing a protocol cDNA library preparation with low input samples used in single cell transcriptomics. allowed us sub-microgram amounts total RNA success. These...
Helminth parasites secrete several types of biomolecules to ensure their entry and survival in hosts. The proteins secreted the extracellular environment participate pathogenesis anthelmintic immune responses. aim this work was identify functionally annotate excretory/secretory (ES) monogenean ectoparasite Rhabdosynochus viridisi through bioinformatic approaches. A total 1655 putative ES were identified, 513 (31%) annotated UniProtKB/Swiss-Prot database, 269 (16%) mapped 212 known protein...
Summary Protein kinases are enzymes involved in essential biological processes such as signal transduction, transcription, metabolism, and the cell cycle. Human targets for several drugs approved by US Food Drug Administration. Therefore, identification classification of other organisms, including pathogenic parasites, is an interesting subject study. Monogeneans platyhelminths, mainly ectoparasites, capable causing health problems farmed fish. Although some genomes transcriptomes available...
Farming of finfish in sea cages is gaining popularity worldwide. These systems are a suitable environment for the emergence, establishment and transmission parasites or pathogens, such as lice (Copepoda: Caligidae), known to cause serious diseases economic losses aquaculture In coastal waters Jaramijó, Ecuador, there plans culture spotted rose snapper (Lutjanus guttatus) longfin yellowtail (Seriola rivoliana); however, information about occurrence on fish from this country scarce. To address...
Abstract We report the nearly complete mitochondrial genome of Rhabdosynochus viridisi – first for this genus achieved by combining shotgun sequencing genomic and cDNA libraries prepared using low-input protocols. This integration information leads us to correct annotation gene features. The consists 13,863 bp. Annotation resulted in identification 12 protein-encoding genes, 22 tRNA genes two rRNA genes. Three non-coding regions, delimited three tRNAs, were found between nad 5 cox 3. A...
Substitution rates in genes can provide information about their evolutionary dynamics and divergence among either species or protein groups. This work presents PANAS, a computational pipeline developed to facilitate the obtention of substitution large amounts genomic data from different taxa. We tested PANAS by analyzing evolution mitochondrial protein-coding (PCGs) 18 platyhelminths. Our results suggest that cox1, cox2, cytb, nad1 are under strong selection pressure at nucleotide level
Los Neodermata son gusanos planos parásitos que tienen un papel relevante en temas de salud pública y veterinaria. Aunque se ha investigado mucho sobre ellos, varios aspectos su historia evolutiva siguen siendo misterio. La investigación tradicional basaba anatomía, pero con avances tecnológicos, el análisis del ADN revelado nuevas conexiones entre diferentes especies. Estos dividen tres clases principales: Monogenea, Trematoda Cestoda. Cada una tiene adaptaciones únicas les permiten...
La combinación de métodos moleculares es cada vez más eficiente para identificar genes en especies no modelo como los monogeneos. Estos organismos son parásitos que pueden causar problemas salud peces cautiverio o condiciones cultivo, por lo importante diseñar tratamientos efectivos ataquen directamente sistemas defensa parásitos. Los transportadores ABC (ATP-binding cassette) proteínas participan procesos detoxificación xenobióticos y mecanismos resistencia a fármacos. En monogeneos escaso...
A new caligid copepod species, Pupulinamantensissp. n. is described based on female and male specimens collected from the gills of myliobatid elasmobranch Aetobatuscf.narinari Euphrasen, 1790 captured off Pacific coast Ecuador. The species has a unique combination characters that diverges its known congeners, including: (i) weakly developed posterolateral processes genital complex; (ii) large spines posterior surface maxilliped basis (iii) abdomen slender, unsegmented, approximately 1/2...
Tetraspanins are a superfamily of transmembrane proteins that in flatworms have structural roles the development, maturation or stability tegument. Several tetraspanins considered as potential candidates for vaccines drugs against helminths. Monopisthocotylean monogeneans ectoparasites fish health hazards farmed fish. The aim this study was to identify silico putative genomic datasets four monopisthocotylean species. analysis predicted and classified 40 Rhabdosynochus viridisi, 39 Scutogyrus...
Fish–parasite systems could be subject to two scenarios under climate change: (i) increased water temperature might enhance parasite metabolism, allowing the spread rapidly; (ii) parasitism decrease if optimal for growth and transmission is exceeded. Sea lice are parasitic copepods commonly found on marine fish in tropical regions, yet their biology remains poorly investigated. In this study, we analyzed changes infection levels transcriptomic response of sea louse Caligus confusus seasonal...
Los peces tienen una diversidad amplia de parásitos. Entre los más conocidos están gusanos monogéneos, capaces causar enfermedades y pérdidas económicas en la producción acuícola. Hay varias formas combatir a estos parásitos, pero resultados no son siempre satisfactorios. Entonces, es necesario continuar realizando investigaciones para encontrar efectivas. Consideramos que exploración del arsenal molecular usan monogéneos atacar puede darnos pistas útiles. ese las proteínas...
