Native and imported Scomber Japonicus were collected from Egypt and found to be infected with the third stage larvae (L3) of Anisakidae. The Anisakidae larvae were found encapsulated tightly coiled in the mesenteries associated with pyloric ceca and the serosal surface of visceral organs and/or uncoiled larvae free in the abdominal cavity of infected S. japonicus. The prevalence, mean intensity, and mean abundance of L3 were 80%, 24.4, and 19.5 in imported fish, and they were 36%, 7.36, and 2.65 in native fish, respectively. These larvae were identified as Anisakis simplex type 1 based on their morphological and molecular characteristics. The larvae were cylindrical in shape, and the oral openings had a prominent boring tooth. The esophago-intestinal junction (ventriculus) was oblique. The bodies of the larvae were covered with a transversely striated cuticle. The posterior end of the larvae had a short mucron or spine. Subsequently, phylogenetic analysis of the internal transcribed spacer region and COI gene of investigated larvae confirmed the identification of A. simplex when compared with relevant species sequences in GenBank. Histopathological examination revealed multiple A. simplex larvae in the abdominal cavity near the pyloric appendages, stomach, and under the visceral peritoneum, which appeared as a very thin and glistening capsule covering the larvae with a prominent adhesive fibrinous peritonitis together with mononuclear and eosinophilic granular cell infiltration. The importance of A. simplex infection in both native and imported S japonicus in Egypt is emphasized.

UNLABELLED: The nucleotide sequence analysis of the gyrB gene indicated that the fish Aeromonas spp. isolates could be identified as Aeromonas hydrophila and Aeromonas veronii biovar sobria, whereas chicken Aeromonas spp. isolates identified as Aeromonas caviae. PCR data revealed the presence of Lip, Ser, Aer, ACT and CAI genes in fish Aer. hydrophila isolates, ACT, CAI and Aer genes in fish Aer. veronii bv sobria isolates and Ser and CAI genes in chicken Aer. caviae isolates. All chicken isolates showed variable resistance against all 12 tested antibiotic discs except for cefotaxime, nitrofurantoin, chloramphenicol and ciprofloxacin, only one isolate showed resistance to chloramphenicol and ciprofloxacin. Fish Aeromonads were sensitive to all tested antibiotic discs except amoxicillin, ampicillin-sulbactam and streptomycin.

SIGNIFICANCE AND IMPACT OF THE STUDY: Many integrated fish farms depend on the application of poultry droppings/litter which served as a direct feed for the fish and also acted as pond fertilizers. The application of untreated poultry manure exerts an additional pressure on the microbial world of the fish's environment. Aeromonas species are one of the common bacteria that infect both fish and chicken. The aim of this study was to compare the phenotypic traits and genetic relatedness of aeromonads isolated from two diverse hosts (terrestrial and aquatic), and to investigate if untreated manure possibly enhances Aeromonas dissemination among cohabitant fish with special reference to virulence genes and antibiotic resistant traits.
