Molecular Identification, Transcriptome Sequencing and Functional Annotation of Pulex irritans.
Article in Acta parasitologica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposePulex irritans are vectors of various zoonotic pathogens. However, molecular studies on P. irritans and flea-borne diseases are limited due to the lack of molecular data. This study aimed to conduct transcriptome sequencing, functional annotation, and pathogen analysis of P. irritans.
methodsFleas collected from a dog were identified morphologically and molecularly. RNA was extracted for transcriptome sequencing and functional annotation. Open reading frames (ORFs) of unigenes were confirmed by employing bioinformatics strategies, and maximum likelihood (ML) trees were reconstructed based on the highly expressed genes of ejaculation globulin-specific 3-like protein, salivary protein, and actin for phylogenetic relationship analysis.
resultsThe obtained mitochondrial 16S rRNA gene sequences showed 99.71% of similarity with P. irritans obtained from GenBank database. Transcriptome sequencing generated 74,412 unigenes, of which 53,211 were functionally annotated. A total of 195 unigenes were assigned to fleas, of which 69 contained complete ORFs. Phylogenetic trees of both ejaculatory globulin and salivary protein genes demonstrated that P. irritans first clustered with Pulicidae sp., indicating the reliability of transcriptome data. It is noteworthy that 1070 unigenes were assigned to Hymenolepis microstoma and Dipylidium caninum, of which 62 contained complete ORFs. The phylogenetic tree of the actin gene showed that the unigenes had closer relationships with Echinococcus sp., suggesting the role of P. irritans as intermediate hosts of tapeworms.
conclusionThe results of this study provide the possibility for functional exploration of important genes and lay foundations for the prevention and control of P. irritans and flea-borne diseases.
