The ciliophoran parasite Apiosoma doliaris (Timofeev, 1962) Lom, 1966 was detected from the gills of fry of both grass carp Ctenopharyngodon idella and common carp Cyprinus carpio during May 2018 at the ponds of Marine Science Centre Fish Hatchery, University of Basrah.. In the present study a brief description of A. doliaris was given. The occurrence of this species represents its first record in Iraq.

Abstract Background: Interferon (IFN) regulatory factors (IRFs), as transcriptional regulatory factors, play important roles in regulating the expression of type I IFN and IFN stimulated genes (ISGs) in innate immune responses. In addition, they participate in cell growth and development and regulate oncogenesis. Results: In the present study, the cDNA sequence of IRF10 in common carp (Cyprinus carpio L.) was characterized (abbreviation, CcIRF10). The predicted protein sequence of CcIRF10 shared 52.7-89.2% identity with other teleost IRF10s and contained a DNA-binding domain (DBD), a nuclear localization signal (NLS) and an IRF-associated domain (IAD). Phylogenetic analysis showed that CcIRF10 had the closest relationship with IRF10 of Ctenopharyngodon idella. CcIRF10 transcripts were detectable in all examined tissues, with the highest expression in the gonad and the lowest expression in the head kidney. CcIRF10 expression was upregulated in the spleen, head kidney, foregut and hindgut upon polyinosinic:polycytidylic acid (poly I:C) and Aeromonas hydrophila stimulation and induced by poly I:C, lipopolysaccharide (LPS) and peptidoglycan (PGN) in peripheral blood leucocytes (PBLs) and head kidney leukocytes (HKLs) of C. carpio. In addition, overexpression of CcIRF10 was able to decrease the expression of the IFN and IFN stimulated genes PKR and ISG15. Conclusions: These results indicate that CcIRF10 participates in antiviral and antibacterial immunity and negatively regulates the IFN response, which provides new insights into the IFN system of C. carpio.
