Probiotics have been widely known to have the ability to improve the immune system of livestock and aquatic animal. The present study was carried out to evaluate the effect of dietary supplementation of two probiotic isolates of Enterococcus faecium on hematological parameters of juvenile African catfish, Clarias gariepinus during pre- and post-challenge with aquatic pathogen, Aeromonas hydrophila. The probiotics were previously isolated from vegetable wastes (mung bean sprouts, Vigna radiate and cucumber, Cucumis sativus) which have been fermented for 7 days. The experimental fish (270 tails) with an average weight of 5.13 ± 1.03 g were distributed and divided randomly  into  i) control (30 tails), fed with commercial diet ii) E1 (30 tails), fed with  diets  supplemented  with  108 CFU/ml  of  E. faecium isolated from fermented cucumber, iii) E2 (30 tails), fed with 108 CFU/ml  of  E. faecium isolated from fermented mung bean sprouts. The feeding trial was conducted for 50 days. All experimental groups were then challenged with A. hydrophila (1.5 × 106 CFU/mL) via intraperitoneal injection on day 51. Prior to challenge, blood samples were collected from five fish randomly selected from each group on the day 51 (pre-challenge).  After 72 hours of post-challenge, blood samples were again collected from five fish from each groups. The hematological parameters such as total erythrocyte count  (RBC),  total  leucocyte  count  (WBC),  packed cell volume (PCV),  hemoglobin  (Hb), the derived blood indices of mean corpuscular volume (MCV) and corpuscular hemoglobin concentration (MCHC) were examined.  Hematological profiles of pre- and post-challenge infected juvenile catfish were compared with the control groups. The RBC, Hb, WBC, PCV, MCV and MCHC of fish fed with probiotics showed higher significant difference (P<0.05) as compared to control groups during pre- and post-challenge of pathogen. The high level of RBC and WBC during pre- and post-challenge showed the capability of the probiotics to improve the immune response of juvenile African catfish and thus increased the fish disease resistance against A. hydrophila infection. The result suggested that E. faecium could be used effectively as a probiotic in aquaculture.

Background: The combination of some plant extracts to prevent and treat bacterial infections is gaining momentum, because of effectiveness against certain bacteria. This study aims to describe the antibacterial and immunostimulant abilities of Boesenbergia pandurata (BP), Solanum ferox (SF) and Zingiber Zerumbet (ZZ) plant extracts to treat and prevent Aeromonas hydrophila and Pseudomonas fluorescens infection on Tilapia (Oreochromis niloticus). Methods: Tilapia (initial weight 15±2 g) were injected intramuscularly (0.1 ml/fish) with a combination of A. hydrophila and P. fluorescens at a density of 1×10 5 CFU ml -1 of each bacteria. Treatment trials were performed at day 7 post-injection with each combined extract, while the prevention trial was performed by including the combined extract into the commercial diet for six and seven days prior to injection. Various extract combinations were 60 mg SF extract/kg feed with 40 mg ZZ/kg feed (SF60/ZZ40), SF50/ZZ50, BP90/SF10, and BP50/SF50. Haemato-immunological parameters were performed for four weeks. Results: In prevention trials, tilapia fed SF50/ZZ50 showed a significant increase of white and red blood cells. Similarly, significantly increased haematocrit was found in tilapia fed SF50/ZZ50 in the treatment trial but not in the prevention trial. In both trials, haemoglobin of tilapia was not affected by any combined extracts but decreased the number of bacteria. Phagocytic index, respiratory burst, lysozyme activity and survival rate of fish fed combined extracts were found significantly higher than controls. The amount of pathogenic bacteria in fish fed combined extracts was lower than the control at week 4 (P<0.05). In both trials The percentage of survival rate and relative percent survival of tilapia fed SF 50/ZZ 50, showed the optimum results compared to the other combinations. Conclusions: The combined extract in feed, especially SF50/ZZ50 has a positive effect on the tilapia's innate immune system of tilapia to treat and prevent bacterial infections.

The aimed of this research was to evaluate the effects of dietary probiotic microcapsules B.cereus P22 and S. lentus (L1k) at different dose and frequency on growth performance, immune response and resistance of African catfish infected with A. Hydrophila. Probiotics used in this study were B. cereus P22 and S. lentus L1k encapsulated by spray draying method. The research was carried out for 56 days with eight treatments and four replications. The treatments were K- (negative control), K+ (positive control), A (feed supplemented with 0,5% of microencapsulated probiotic, fedevery day), B (feed supplemented with 0,5% of microencapsulated probiotic, fed once every three days), C (feed supplemented with 1% of microencapsulated probiotic, fed every day), D (feed supplemented with 1% of microencap-sulated probiotic with an administration once every three days), E (feed with 2% of microencapsulated probiotic with an administration every day) and F (feed with 2% of microencapsulated probiotic with an administration once every three days). On day 42, all of the fish except K- were challenged by intramuscular injection of A. hydrophila (108 CFU ml-1). In 40 days after infection, there were no significant difference on survival rate (SR) between treatments (p> 0.05). Treatment E displayed the higher growth rate (4,54±0,02%), total probiotic B. cereus (P22) and S . lentus (L1k) (4.06± 0.09 log CFU g-1; 4.02±0.08 log CFU g-1) than other treatments; whereas treatment D showed the best feed conversion rasio(1.191±0.013), and treatment F offered the highest total bacterial count (7.11±0.53 log CFU g-1). An administration of 2% microencapsulated probiotic in every day frequency demonstrated the better growth performance, immune res-ponse and resistance of African catfish to A. hydrophila compare with other treatments. AbstrakPenelitian ini bertujuan untuk mengkaji dosis dan frekuensi pemberian mikrokapsul probiotik melalui pakan terhadap kinerja pertumbuhan, respons imun, dan resistensi ikan lele yang diinfeksi Aeromonas hydrophila. Penelitian ini meng-gunakan Bacillus cereus P22 dan Staphylococcus lentus L1k yang telah dienkapsulasi melalui metode spray draying. Penelitian ini dilaksankan selama 56 hari dengan delapan perlakuan dan empat ulangan, terdiri atas perlakuan K- (kon-trol negatif), K+ (kontrol positif), A (pakan+mikrokapsul probiotik dosis 0,5% frekuensi setiap hari), B (pakan+mikro-kapsul probiotik dosis 0,5% frekuensi tiga hari sekali), C (pakan+mikrokapsul probiotik dosis 1% frekuensi setiap hari), D (pakan+mikrokapsul probiotik dosis 1% frekuensi tiga hari sekali), E (pakan+mikrokapsul probiotik dosis 2% fre-kuensi setiap hari) dan F (pakan+mikrokapsul probiotik dosis 2% frekuensi tiga hari sekali). Ikan diuji tantang dengan A. hydrophila pada hari ke 42 dengan kepadatan 108 CFU ml-1 secara intramuscular (kecuali K- diinjeksi dengan phos-phate buffer saline). Setelah 40 hari pascainjeksi, laju sintasan tidak menunjukkan perbedaan yang signifikan antarperlakuan (p>0,05).Perlakuan E menunjukkan laju pertumbuhan (4,54±0,02%) dan total probiotik B. cereus (P22) dan S. lentus (L1k) (4,06±0,09 log CFU g-1; 4,02±0,08 log CFU g-1) tertinggi; sementara perlakuan D memberikan hasil nisbah konversi pakan terbaik (1,191±0,013), perlakuan F menunjukkan total bacterial count tertinggi (7,11±0,53 log CFU g-1). Hasil penelitian menunjukkan bahwa dosis 2% yang diberikan setiap hari memberikan hasil yang lebih baik dalam meningkatkan laju pertumbuhan, respons imun, dan resistensi ikan lele terhadap A. hydrophila.

Methods: Tilapia (initial weight 15±2 g) were injected intramuscularly (0.1 ml/fish) with a combination of A. hydrophila and P. fluorescens at a density of 1×105 CFU ml-1 of each bacteria. Treatment trials were performed at day 7 post-injection with each combined extract, while the prevention trial was performed by including the combined extract into the diet for six and seven days prior to injection. Various combinations of extract—60 ml SF extract/kg feed with 40 ml ZZ/kg feed (SF60/ZZ40), SF50/ZZ50, BP90/SF10, and BP50/SF50—were mixed with a commercial diet and used in both treatment and prevention trials. Haematological and immunological parameters were performed every week for four weeks. Results: In prevention trials, tilapia fed SF50/ZZ50 showed a significant increase of white and red blood cells from weeks 2 to 4. Similarly, significantly increased haematocrit was also found in tilapia fed SF50/ZZ50 in the treatment trial but not in the prevention trial. However, haemoglobin of tilapia in both trials was not affected by any of the various combinations of extract in the diet. Furthermore, phagocytic, respiratory burst, lysozyme activity indexes and survival rate of fish fed with combined extracts were found to be significantly higher than controls. Moreover, the amount of pathogenic bacteria in fish that were fed combined extracts was also lower than the control and was significantly different at week 4. Conclusions: This study indicates that the addition of combined extract into feed has a positive effect on the tilapia's immune system. The SF50/ZZ50 combination appears to improve the innate immune system of tilapia to treat and prevent bacterial infections.
