“…EAggEC was isolated from almost 20% of the cases and is of concern due to its likely relationship, even in the absence of diarrhea, with stunting in developing countries. 29 Aeromonas was identified to be statistically significantly associated with case status, providing 30 Unlike previous findings in Thailand and China, Campylobacter spp. were not major causes of diarrhea in this population and were equally or more common in the controls than the cases.…”

This research aimed to characterize bacteria caused disease in eel Anguilla bicolor bicolor. The research was conducted in two steps. The first step included the isolation and identification of bacteria from the disease infected glass eel (average body length: 5.0 ± 0.5 cm, average weight: 0.5 ± 0.1 g). The observation were colony and cell morphology, physiology, and biochemical characterization of bacteria, hemolysis test, and bacteria identification performed by KIT API 20 E, KIT API 20 Strep, and KIT API 20 Listeria. The second step was Koch's postulate, tested on healthy elver with an average length of 15.00 ± 0.65 cm and weight of 3.00 ± 0.75 g. The results showed three dominant species of bacteria suspected as a causative agent in eel, namely: Aeromonas hydrophila, Streptococcus agalactiae, and Listeria grayi. Koch's postulates test proved that the Aeromonas hydrophila and Streptococcus agalactiae were virulent to Anguilla bicolor bicolor. Thus, A. hydrophila and S. agalactiae were disease-causing agent bacteria in eel.Keywords: Anguilla bicolor bicolor, bacteria, A. hydrophila, S. agalactiae. ABSTRAKPenelitian ini bertujuan untuk mengkarakterisasi bakteri penyebab penyakit pada ikan sidat Anguilla bicolor bicolor. Penelitian ini dilakukan dalam dua tahap. Tahap pertama meliputi isolasi dan identifikasi bakteri dari ikan sidat kondisi sakit pada stadia glass eel. Ukuran panjang ikan sidat rata-rata 5 ± 0,5 cm dan bobot ratarata 0,5 ± 0,08 g, pengamatan bentuk morfologi koloni dan morfologi sel, karakterisasi fisiologi, dan biokimia bakteri, serta uji hemolisis, dan identifikasi jenis bakteri dengan KIT API 20 E, KIT API 20 Strep, dan KIT API 20 Listeria. Tahap kedua yaitu uji postulat Koch pada ikan sidat kondisi sehat stadia elver yang berukuran panjang rata-rata 15 ± 0,65 cm dan bobot rata-rata 3 ± 0,75 g. Hasil penelitian diperoleh tiga jenis bakteri dominan yaitu Aeromonas hydrophila, Streptococcus agalactiae, dan Listeria grayi. Uji postulat Koch membuktikan bahwa bakteri A. hydrophila dan S. agalactiae bersifat virulen pada ikan sidat Anguilla bicolor bicolor. Dengan demikian maka bakteri A. hydrophila dan S. agalactiae sebagai bakteri penyebab penyakit pada ikan sidat.Kata kunci: Anguilla bicolor bicolor, bakteri, A. hydrophila, S. agalactiae

“…They are known to be pathogenic to poikilothermic animals, causing ulcerative infections, and recently have been found to be associated with a variety of human extra-intestinal infections 17 . Their role as diarrhea causing agents is still controversial 12 as some studies have found aeromonads carried as transient flora in healthy asymptomatic individuals 2,15,17 .…”

SUMMARYThis work aimed to assess pathogenic potential and clonal relatedness of Aeromonas sp. and Vibrio cholerae isolates recovered during a diarrhea outbreak in Brazil. Clinical and environmental isolates were investigated for the presence of known pathogenic genes and clonal relatedness was assessed by intergenic spacer region (ISR) 16S-23S amplification. Four Aeromonas genes (lip, exu, gcat, flaA/B) were found at high overall frequency in both clinical and environmental isolates although the lip gene was specifically absent from selected species. A fifth gene, aerA, was rarely found in A. caviae, the most abundant species. The ISR profile revealed high heterogeneity among the Aeromonas isolates and no correlation with species identification. In contrast, in all the V. cholerae isolates the four genes investigated (ctxA, tcpA, zot and ace) were amplified and revealed homogeneous ISR and RAPD profiles. Although Aeromonas isolates were the major enteric pathogen recovered, their ISR profiles are not compatible with a unique cause for the diarrhea events, while the clonal relationship clearly implicates V. cholerae in those cases from which it was isolated. These results reinforce the need for a better definition of the role of aeromonads in diarrhea and whether they benefit from co-infection with V. cholerae.
