  • Dietary supplement of Enterococcus faecalis on digestive enzyme activities, short‐chain fatty acid production, immune system response and disease resistance of Javanese carp (Puntius gonionotus, Bleeker 1850)
    'Wiley', 2017
    Co-Authors: Allameh, Sayyed Kamaleddin, Ringo Einar, Md Yusoff Fatimah, Mohd Daud Hassan, Ideris Aini
    Abstract:

    This study investigated the effects of Enterococcus faecalis on digestive enzyme activities and short‐chain fatty acid production in fish intestine, resistance against Aeromonas hydrophila and humoral immunity response by 3 experiments on Javanes carp (Puntius gonionotus). The experiment 1 revealed that diet supplemented with E. faecalis significantly (P 0.05) in acetic acid production was observed. In the challenge study (experiment 2), fish were injected (intraperitoneal) with 107 A. hydrophila per ml and survival was significantly improved when fish were fed diet supplemented with E. faecalis compared to control fish. In experiment 3, dietary E. faecalis affected immune system response as fish fed the probiont and exposed to 106 A. hydrophila per ml displayed significantly elevated antibody levels compared to control fed fish. Fish fed diet supplemented with E. faecalis but not exposed to the pathogen revealed significantly higher antibody level than control fish (P < 0.05). Therefore, E. faecalis can be used as a probiotic in Javanese carp farming

    Co-Authors: Sayyed Kamaleddin Allameh, Einar Ringo, Fatimah Md Yusoff, Hassan Mohd Daud, Aini Ideris
    Abstract:

    This study investigated the effects of Enterococcus faecalis on digestive enzyme activities and short-chain fatty acid production in fish intestine, resistance against Aeromonas hydrophila and humoral immunity response by 3 experiments on Javanes carp (Puntius gonionotus). The experiment 1 revealed that diet supplemented with E. faecalis significantly (P   0.05) in acetic acid production was observed. In the challenge study (experiment 2), fish were injected (intraperitoneal) with 107 A. hydrophila per ml and survival was significantly improved when fish were fed diet supplemented with E. faecalis compared to control fish. In experiment 3, dietary E. faecalis affected immune system response as fish fed the probiont and exposed to 106 A. hydrophila per ml displayed significantly elevated antibody levels compared to control fed fish. Fish fed diet supplemented with E. faecalis but not exposed to the pathogen revealed significantly higher antibody level than control fish (P < 0.05). Therefore, E. faecalis can be used as a probiotic in Javanese carp farming.

  • Herbicide Diuron as endocrine disrupting chemicals (EDCs) through histopathalogical analysis in gonads of Javanese medaka (Oryzias javanicus, Bleeker 1854)
    'MDPI AG', 2020
    Co-Authors: Kamarudin, Nur Amiera, Zulkifli, Syaizwan Zahmir, Azmai, Mohammad Noor Amal, Abdul Aziz, Fatin Zahidah, Ismail Ahmad
    Abstract:

    The expeditious augmentation of the agriculture industry is leaving a significant negative impact on aquatic ecosystems. However, the awareness of the impacts of herbicide Diuron toxicities on the non-targeted aquatic organism, especially fish is still lacking. Javanese medaka, a new model fish species were exposed under sublethal levels and the long-term effects on gonads were investigated via histological studies. A total of 210 sexually mature fish were exposed to Diuron at seven different concentrations; control, solvent control, 1, 50, 100, 500, and 1000 μg/L for 21 days. In this study, Diuron caused histopathological alterations in gonads (ovary and testis) of Javanese medaka (Oryzias javanicus) by decreasing in gonadal staging and maturity of germ cells in oogenesis and spermatogenesis of female and male Javanese medaka. The results obtained in this study had proven our hypothesis that long-term exposure of herbicide Diuron can cause alterations in the gonadal histology of the adults of Javanese medaka

  • Javanese medaka (Oryzias javanicus Bleeker, 1854) as potential model organism for aeromoniasis and vibriosis study in fish
    Universiti Putra Malaysia Press, 2019
    Co-Authors: Azmai, Mohammad Noor Amal, Ismail Ahmad, Mohd Roseli, Mohd Fauzul Aidil, Sutra Jumria, Roslan Syuhada, Mazlan, Siti Nur Khamisah, Basri Lukman, Lee, Jing Yie, Mohamad Nurliyana, Saad, Mohd Zamri
    Abstract:

    Javanese medaka is a small tropical fish that has been widely used as a test organism in ecology, toxicology and ecotoxicology, but less in fish-pathogen related study. This study evaluates the capability of Javanese medaka as an alternative model organism for aeromoniasis and vibriosis study in fish. Javanese medakas were infected with different concentrations of Aeromonas hydrophila, Vibrio alginolyticus and V. harveyi via intraperitoneal (IP) and immersion (IMM) routes. Following the infections, the LD50- 240h of all bacteria to Javanese medaka were observed lower in IP, compared with IMM route. In IP route, the LD50-240h ranged from 2.1 × 104 CFU/mL for V. harveyi to 2.5 × 107 CFU/mL for A. hydrophila. However, for IMM route, the range was from 6.6 × 107 CFU/mL for V. harveyi to 1.1 × 109 CFU/ mL for V. alginolyticus. The clinical signs, gross lesions and histopathological changes of Javanese medakas infected by either IP or IMM routes of all the pathogens were similarly observed in the real host of the pathogen. Moreover, in IP route, most of the fish mortalities (88.9%) were observed within ≤ 120 hours post infection (hpi), while for IMM, most of the mortalities (50.6%) were witnessed beyond 120 hpi, indicating the acute infection for IP compared to IMM route. This study highlights the potential utilization of Javanese medaka as another valuable in vivo model organism for bacterial diseases study in fish
