Opis:
The purpose of this study was to distinguish histopathological changes in carp fish (Carassius auratus) infected by Aeromonas hydrophila with different densities. Five treatments were used in the survey for this research method. The treatments used were bacterial infusion of A. hydrophila in the test fish through intramuscular injection with various densities, namely: A. without infection, B: 105 CFU/mL, C: 106 CFU/mL, D: 107 CFU/mL, and E: 108 CFU/mL. The parameters observed were histopathological changes in gill organs, kidneys and hearts of carp fish (gold fish). Data from histopathological observations were analyzed descriptively. The results present gill organs, liver and kidneys of carp fish infected with the bacteria A. hydrophila at various densities experiencing histopathological changes in the form of hemorrhages, necrosis and congestion and hyperplasia of the renal tubules. Other changes that occur were in the kidney organ experiencing a melanomacrophage center (MC). Tubules were coated with connective tissue and lymphocyte infiltration. The most severe organ damage that occurs in carp fish infected with the bacteria A. hydrophila at a density of 108 CFU/mL (treatment E) is shown by a low survival of 5%.

Opis:
This research aims to determine the effective dosage of potassium diformate (KDF) in feed to enhance sangkuriang catfish immune performances. The research was conducted on November - January 2019, at Aquaculture Laboratory Building No. 4 Faculty of Fisheries and Marine Sciences Universitas Padjadjaran. This study used an experimental method of Completely Randomized Design (CRD), with four treatments and three replications. The treatments are the addition of potassium diformate into feed with doses A (0%), B (0.5%), C (0.7%) and D (0.9%). Observed parameters are clinical symptoms, total leukocyte count, total erythrocyte count, specific growth rate, survival rate and water quality. The results showed that 0.5% KDF feed produced the highest survival rate of 85% and the highest specific growth rate of 3.59% after 40 days. Furthermore, due to treatment, total erythrocyte count increased from 2.09×106 cells/mm3, to 2.10×106 cells/mm3 (8.1%) and total leukocyte count increased from 7.1×104 cells/mm3, to 10.7×104 cells/mm3 (42.81%). The addition of 0.5% KDF in feed is effective in improving the immune performances of sangkuriang catfish challenged by A. hydrophila, with the highest survival rate of 97%. Moreover, recovery of total leukocyte count and total erythrocyte count was faster than other treatments as of day 7th, with a value 1.97×106 sel/mm3and 12.60×104 sel/mm3. It also resulted in the lowest gross clinical signs and the fastest recovering.

The present study investigates phytochemical screening and antibacterial efficacy of various solvent extracts of marine algae such as Sargassum swartzii against some selected human and fish pathogenic bacteria. The brown seaweed Sargassum swartzii was collected from Kudankulam, Tirunelveli district, Tamil Nadu, India. Soxhlet extraction method was used to get the extracts of different solvents like aqueous, ethanol, methanol, acetone and were tested for their qualitative phytochemical screening using common standard tests. Quantitative phytochemical analysis such as total phenolic content and total flavonoid content of S. swartzii and antibacterial activity against human pathogens viz., Escherichia coli, Pseudomonas aeruginosa and Stephylococcus aureus and fish pathogens viz., Aeromonas hydrophila and Vibrio vulnificus bacteria using disc diffusion methods. Preliminary phytochemical screening of sixteen different chemical compounds were carried out. The maximum biochemical compounds were present in the ethanol extract and the minimum compounds were present in aqueous extract. The ethanol extract was significantly higher in phenolic content (15.35 ±2.61 mg of GAE/g) and the methanol extract was significantly higher in flavonoides content (26.92±7.14 mg of QE/g). In human pathogen the highest antibacterial activity was present in Pseudomonas aeruginosa (18.00±0.00mm) and the fish pathogen was significantly higher in Aeromonas hydrophila. The present study showed that the ethanol extract of marine brown seaweed Sargassum swartzii contains bio active constituents with highest antibacterial activity against human and fish pathogen.

Opis:
Food preservation using high pressure is a promising technique in food industry as it offers numerous opportunities for developing new foods with extended shelf-life, high nutritional value and excellent organoleptic characteristics. High pressure is an alternative to thermal processing. The resistance of microorganisms to pressure varies considerably depending on the pressure range applied, temperature and treatment duration, and type of microorganism. Generally, Gram-positive bacteria are more resistant to pressure than Gram-negative bacteria, moulds and yeasts; the most resistant are bacterial spores. The nature of the food is also important, as it may contain substances which protect the microorganism from high pressure. This article presents results of our studies involving the effect of high pressure on survival of some pathogenic bacteria - Listeria monocytogenes, Aeromonas hydrophila and Enterococcus hirae - in artificially contaminated cooked ham, ripening hard cheese and fruit juices. The results indicate that in samples of investigated foods the number of these microorganisms decreased proportionally to the pressure used and the duration of treatment, and the effect of these two factors was statistically significant (level of probability, P ≤ 0.001). Enterococcus hirae is much more resistant to high pressure treatment than L. monocytogenes and A. hydrophila. Mathematical methods were applied, for accurate prediction of the effects of high pressure on microorganisms. The usefulness of high pressure treatment for inactivation of microorganisms and shelf-life extention of meat products was also evaluated. The results obtained show that high pressure treatment extends the shelf-life of cooked pork ham and raw smoked pork loin up to 8 weeks, ensuring good micro-biological and sensory quality of the products.

Opis:
Aeromonas hydrophila is a valuable indicator of the quality of water polluted by sewage and pathogens that pose a risk for humans and cold-blooded animals, including fi sh. The main aim of this research was to evaluate anthropogenic pollution of river water based on genetic diversity of 82 A. hydrophila strains by means of RAPD, semi-random AP-PCR (ISJ) and the rep-BOX conservative repeats test. Genetic diversity of A. hydrophila was HT = 0.28 (SD = 0.02) for all DNA markers (RAPD, semi random and rep-BOX). None of the analyzed electrophoretic patterns was identical, implying that there were many sources of strain transmission. The presence of genes for aerolysin (aerA), hemolysin (ahh1) and the cytotoxic enzyme complex (AHCYTOGEN) was verifi ed for all tested strains, and drug resistance patterns for tetracycline, enrofl oxacin and erythromycin were determined. The most diverse A. hydrophila strains isolated from river water were susceptible to enrofl oxacine (HS = 0.27), whereas less diverse strains were susceptible to erythromycin (HS = 0.24). The presence of the multidrug resistance marker (ISJ4-25; 1100 bp locus) in the examined strains (resistant to three analyzed drugs) indicates that intensive fi sh cultivation affects the microbiological quality of river water.
Aeromonas hydrophila jest cennym wskaźnikiem jakości wody w przypadku zanieczyszczeń ściekami oraz mikroorganizmami względnie patogennymi dla człowieka i zwierząt zimnokrwistych, w tym ryb. Celem niniejszych badań była ocena zanieczyszczenia antropogenicznego na podstawie zróżnicowania genetycznego 82 szczepów A. hydrophila poprzez analizy RAPD, pół-przypadkowo amplifi kowanej klasy AP-PCR (ISJ) i konserwatywnego powtórzenia rep-BOX. Zróżnicowanie genetyczne A. hydrophila wyniosło HT = 0,28 (SD = 0,02) dla wszystkich markerów DNA (RAPD, pół-przypadkowe i rep-BOX). Wszystkie szczepy dla wszystkich markerów ujawniły indywidualny wzór elektroforetyczny, nie ujawniono jednego źródła rozprzestrzeniania się szczepów. U szczepów potwierdzono obecność genów aerolizyny (aerA), hemolizyny (ahh1) i kompleksu enzymów cytotoksycznych (AHCYTOGEN), jak również określono wzorzec oporności na tetracyklinę, enrofl oksacynę i erytromycynę. Najbardziej zróżnicowane okazały się szczepy A. hydrophila wrażliwe na enrofl oksacynę (HS = 0,27) a najmniej zróżnicowane były szczepy wrażliwe na erytromycynę (HS = 0,24). Wyselekcjonowany marker wielolekooporności (locus ISJ4-25, 1100 pz) obecny u szczepów (opornych na 3 rozpatrywane leki) świadczy o wpływie intensywnej hodowli ryb na jakość mikrobiologiczną wody rzecznej.

The method used is experimental with a completely randomized design (CRD) consisting of three treatments and five replications. The fish are kept at 24 ºC (control without heater), 29 ºC and 34 ºC. Each experimental unit contains 10 fishes. The results obtained by the survival rate (SR) of Common carp strain Majalaya which were maintained at a treatment temperature of 24 ºC by 100%, the 29 ºC by 70%, the 34 ºC by only 42% remained on the 21st day. The number of erythrocytes of common carp strain Majalaya fingerlings before the treatment temperature was 2.77 × 106 cells/mm3. The average number of erythrocytes of the 24ºC treatment from 7th, 14th and 21st day were 2.82, 2.82 and 2.81 × 106 cells/mm3; the 29 ºC were 2.93, 2.68 and 2.42 × 106 cells/mm3; the 34 ºC were 3.08, 2.52 and 1.99 × 106 cells/mm3. While the number of leukocytes of common carp strain Majalaya fingerlings before the treatment temperature was 13.61 × 104 cells/mm3. The average number of leukocytes of the 24 ºC treatment from 7th, 14th and 21st day were 13.73, 13.71 and 13.88 × 104 cells/mm3; the 29 ºC were 18.40, 16.46 and 15.76 × 104 cells/mm3; the 34 ºC were 20.78, 18.46 and 16.81 × 104 cells/mm3.
