Morphological and molecular characterization of Fasciola isolates from livestock in Golestan province, northern Iran.
Article in Veterinary medicine and science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundFascioliasis, caused by the liver flukes Fasciola hepatica and Fasciola gigantica, is a global zoonotic helminthic disease. The livestock and human are the final hosts of the parasites. Northern Iran is an important endemic region for fascioliasis. Few studies have been conducted on the characterization of Fasciola isolates from eastern regions of the Caspian littoral of the country.
objectiveThe aim of the present study was to identify F. hepatica, F. gigantica and intermediate/hybrid forms of Fasciola isolates from livestock in Golestan province, northern Iran, using morphometric and molecular tools.
methodsLivestock livers naturally infected with Fasciola spp. were collected from Golestan slaughterhouse during 2019-2020. The worms were morphometrically studied using a calibrated stereomicroscope. Genomic DNA was extracted from all samples, and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed on internal transcribed spacer (ITS1) region using Rsa1 restriction enzyme. All the isolates were then analysed by multiplex PCR on Pepck region.
resultsA total of 110 Fasciola isolates were collected from the infected livers, including 94 sheep, 12 cattle and 4 goats. Morphometric analysis of 61 adult Fasciola isolates indicated that, 44 and 17 isolates belonged to F. hepatica and F. gigantica, respectively. Eighty-one and 29 isolates belonged to F. hepatica and F. gigantica using ITS1-RFLP, respectively. However, Pepck Multiplex PCR indicated 72 F. hepatica, 26 F. gigantica and 12 intermediate/hybrid forms. All 12 hybrid isolates were found in sheep host. Two isolates were identified as F. gigantica using morphometry and F. hepatica using both molecular methods.
conclusionThe present study confirmed the existence of both F. hepatica and F. gigantica species and reported the first molecular evidence of hybrid Fasciola isolates in ruminants of Golestan province.
