Characterization, isolation and identification of bacteria and parasites in glass eel (Anguilla spp.) in cagayan, Philippines

Abstract

The research focused on identifying bacteria and parasites found in glass eels collected from the province of Cagayan. The characterization, isolation, and identification of bacteria were conducted through morphological analysis involving size, elevation, margin, and pigmentation characteristics, as well as the API 20E test, while parasites were assessed using morphological examination or gross inspection. The prevalence of the identified bacterial and parasitic species was calculated, obtaining percentages of: Elizabethkingia meningoseptica (43.24%), Pseudomonas luteola (32.43%), and Pseudomonas oryzihabitans (16.21%). The bacteria identified from the glass eels included Elizabethkingia meningoseptica, Pseudomonas luteola, Pseudomonas oryzihabitans, and Pseudomonas aeruginosa. The parasites identified were Trichodina spp. and Dactylogyrus spp. Additional confirmation regarding the epizootiology features of the identified bacteria and parasites is required, along with an evaluation of their presence in the water. Moreover, it is essential to investigate the impact of water quality on the occurrence of pathogenic agents in future studies.
