“…cryaerophilus infection could cause a decrease in serum cholesterol and triglyceride values of rainbow trout. Although serum cholesterol and triglyceride concentrations may significantly increase with Serratia liquefaciens infection (Aydin et al, 2001), Vibrio vulnificus infection (Chen et al, 2004) and nephrocalcinosis (Chen et al, 2002), they can also decrease with natural and experimental infections of A. cryaerophilus in rainbow trout (Aydin et al, 2000) and albino crosses of rainbow trout (Bulut and Aydin, 2004), A. hydrophila infection in carp (Harikrishnan et al, 2003) and Streptococcus iniae infection in tilapia (Chen et al, 2004) as was the case in our study. In this work a correlation was observed between changes of serum triglyceride and cholesterol concentrations.…”

“…Those blood characteristics, for which a relationship with a disease state has been established, have been primarily for major cultured fish species. Researchers indicated that the study of some haematological and biochemical parameters in fish blood has been associated with infectious diseases (Aydin et al, 1997(Aydin et al, , 2000(Aydin et al, , 2001(Aydin et al, , 2002Chen et al, 2004), nutritional deficits (Chen et al, 2004), physiological activity (Chen et al, 2004), toxicity (Chen et al, 2002;Yang and Chen, 2003), anoxic conditions and the other environmental factors in fish farming. However, an experimental approach to reveal the link between disease state and clinical pathology is still urgently needed for many teleost species.…”

Arcobacter cryaerophilus was isolated from naturally infected rainbow trout (Oncorhynchus mykiss Walbaum), and its pathogenicity was tested by intramuscular injection into 40 healthy 1-year-old rainbow trout at 16 °C. The lethal dosage of 50% end point (LD 50 ) for A. cryaerophilus was calculated 2.25 × 10 4 viable cells. Experimental infection caused deaths with gross clinical abnormalities such as degenerated opercula and gills, liver damage, haemorrhagic kidney and serous fluid in swollen intestines. The counts of A. cryaerophilus in kidney, liver and gills of experimentally infected fish ranged from 1.59 × 10 10 colony forming units (cfu)/g to 7.41 × 10 12 cfu/g. The means of erythrocyte (RBC) count, haematocrit level, serum cholesterol, triglyceride, albumin and total protein concentrations in the blood of the experimentally infected rainbow trout group were significantly lower than in the healthy fish. Leukocyte (WBC) counts of the experimentally infected rainbow trout were significantly higher than those of healthy fish. The present work shows that the selected blood characteristics may be good indicators of response to infections in rainbow trout.

“…Glucose, triglycerides and serum albumin whilst showed statistically significant higher values. These differences of the biochemical parameters in the two studied fish groups are a consequence of the influence of the different habitat conditions and in particular of the different environment conditions as proven by other researches (Jiraseket al, 1998;Hrubecet al, 2000;Chen et al, 2003;Mensingeret al, 2005;Aras et al,2008. Haematological and biochemical parameters have been acknowledged as valuable tools for monitoring fish health and their normal values are still undefined for the different species of cultured fish. The results of this preliminary study provide the knowledge of the characteristics of blood parameters of rainbow trout O. mikissfrom two different countries and allow a better understanding of the environmental conditions influence on the haematological and biochemical parameters of rainbow trout farmed in two different areas.…”

Blood parameter assessments of fish may be used as quick tools for diagnosing health status. The aim of this research was to undertake a comparative study of hematological and biochemical parameters of Italian and Turkish farmed rainbow trout Oncorhynchusmykiss (Walbaum, 1792) to establish baseline values in relation to different areas. Forty Italian trout (32.59±0.25 cm total length, 397.40±6.49 g weight) and forty Turkish trout (33.00±0.24 cm total length, 385.70±3.50 g weight) were examined.Statistical analysis (unpaired t-test) showed no significant differences in weight, length and condition factor between two farmed trout groups. Statistically significant differences (P < 0.05) were found in some hematological and biochemical parameters between Italian and Turkish farmed rainbow trout.Our findings shown that in Italian farmed rainbow trout Red blood cell (RBC), Hematocrit (Hct), Cholesterol and Total protein values were significantly lower than Turkish trout, instead Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH), Mean corpuscular hemoglobin concentrations (MCHC), Glucose, Triglycerides and Serum albumin shown significantly higher values. No statistically significant differences were found for White blood cell (WBC) and hemoglobin (Hgb).The results of this study contribute to knowledge of the baseline of hematological and biochemical parameters of rainbow trout farmed in two different habitats suggesting that blood parameters could be an important value in monitoring environmental conditions on fish physiology and fish culture management.

“…Total protein is used to evaluate protein metabolism (Aydin et al, 2000), and it is a significant indicator of homeostasis (Řehulka and Minařík, 2007). Decreased total serum protein has been reported with A. cryaerophilus infections (Aydin et al, 2000;Bulut and Aydin, 2004;Yildiz and Aydin, 2006), yersiniosis (Altun and Diler, 1999), Serratia liquefaciens infection (Aydin et al, 2001), motile Aeromonas septicaemia (Harikrishnan et al, 2003), streptococcosis (Chen et al, 2004), natural Aeromonas sobria and Aeromonas caviae infections (Řehulka, 2002), and nephritic syndrome (Chen et al, 2002). Research on the function and uses of serum albumin continues to be of great interest because of the dominant position of albumin in the plasma proteins.…”

“…A fall in albumin concentration may be ascribed to its elevated catabolism which increases in cases of inflammation and reduced food intake, which also often accompany infectious diseases (Ře-hulka and Minařík, 2007). Significant declines of serum albumin level have been reported in natural and experimental infections with A. cryaerophilus (Aydin et al, 2000;Bulut and Aydin, 2004;Yildiz and Aydin, 2006), yersiniosis (Altun and Diler, 1999), Aeromonas and Streptococcus infections (Barham et al, 1980), coldwater vibriosis (Waagbø et al, 1988), Vibrio anguillarum infection (Harbell et al, 1979), furunculosis (Møyner, 1993), and nephrocalcinosis (Chen et al, 2002).…”

Arcobacter cryaerophilus was isolated from naturally infected rainbow trout ( Oncorhynchus mykiss Walbaum), and its pathogenicity was tested by intramuscular injection using healthy 1-year-old rainbow trout under cold-water conditions (at 5 °C). The lethal dosage of 50% end point (LD 50 ) for A. cryaerophilus was calculated as 7.79 × 10 5 viable cells. Experimental infection caused gross clinical abnormalities such as fallen scales, exophthalmia, oedema in injection region and at the base of fins, pale gills, kidney necrosis, hyperaemic areas in pale liver, haemorrhagic spots in heart, elongated spleen and swollen gallbladder. Activities of aspartate aminotransferase and alkaline phosphatase, and concentrations of glucose, total protein, albumin, cholesterol, triglyceride and calcium in the serum of the experimentally infected rainbow trout were significantly decreased compared with the healthy fish. Positive correlations were observed among blood parameters. Total lipid weights increased in the brain, muscle and liver tissues of infected fish and dropped in the gill and spleen tissues. Lipid peroxide contents in the brain, liver, kidney, spleen, muscle and gill tissues of infected rainbow trout were significantly higher than in healthy animals. The present work shows that A. cryaerophilus can be moderately virulent for rainbow trout at low water temperature, and changes in lipid and lipid peroxide contents of tissues and blood indices can highlight barely detectable effects of A. cryaerophilus infection in rainbow trout under laboratory conditions. However, the application of these indices in farm biomonitoring using rainbow trout will need more detailed studies and a careful consideration of the environmental parameters.
