Clinical Significance of Some Acute Phase Proteins in Cattle

Acute phase proteins are proteins synthesized by the liver in response to the acute phase response. While these proteins are insignificant in healthy animals, their concentrations increase rapidly during infection, inflammation, or tissue damage and are used as an indicator of inflammation. Since the blood concentrations and importance levels of these clinically important proteins differ according to the animal species, they are evaluated separately for each animal species. Most of the acute phase proteins have been studied in detail in the field of human medicine and are routinely used in the diagnosis and prognosis of diseases. In the field of veterinary medicine, it has not been used sufficiently. In this book chapter, we will provide up-to-date information about acute phase proteins that are important for cattle, as well as explain that acute phase proteins can be used in the early diagnosis of diseases, in the differentiation of viral and bacterial infections, in guiding the treatment of sick animals and in determining their prognosis

Nitric oxide levels, total antioxidant and oxidant capacity in cattle with foot-and-mouth-disease

The aim of this study was to investigate total antioxidant (TAC), oxidant capacity (TOC) and nitric oxide levels (NO) in cattle with foot-and-mouth-diseases (FMD). Twenty Swiss Brown cattle aged between 24 and 48 months were used. Animals were divided into two groups as control (n=10) and FMD (n=10). Blood samples were collected from jugular vein and centrifuged. TOC and NO levels were found to be significantly higher in FMD group compared to those of control group. However, no significant differences were present in TAC levels between FMD and control groups. It was concluded that FMD increases serum NO levels and TOC, but do not affect TAC in cattle

Investigation of haptoglobin, serum amyloid A, and some biochemical parameters in calves with omphalitis

Aim: In this study, it was aimed to determine the concentration of some important acute phase proteins (APPs) and some biochemical parameters pre-operative and post-operative in calves with omphalitis. Materials and Methods: A total of 20 calves were used in the study and they consist of 10 clinically healthy calves that were used as a control and 10 calves with omphalitis were used as the treatment group. Blood samples were collected from Vena jugularis of animals to tubes with anticoagulant (sodium citrate) and without anticoagulants, pre-operative (day 0), and post-operative (day 7). Samples were used to determine the concentration of haptoglobin (Hp), serum amyloid A (SAA), ceruloplasmin (Cp), fibrinogen, glucose, total protein, albumin, urea, total bilirubin, creatinine, calcium, phosphorus, aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) concentrations. Results: While the Hp, SAA, Cp, fibrinogen, urea, creatinine, total bilirubin, ALP, and GGT concentrations were statistically and significantly increasing rather than the control group during the pre-operative period for calves with omphalitis, they decreased to the post-operative period. Moreover, an insignificant increase in the glucose, total protein, and AST concentrations and an insignificant decrease in the albumin, calcium, and phosphorus concentrations were statistically determined. Conclusion: We have the opinion that the assessment of biochemical parameters and especially APP levels in calves with the omphalitis together with the clinical findings may be important in terms of the treatment and prognosis

The effects of different monochromatic colors on oxidant antioxidant balance in broilers

Poultry management is associated with light due to positive effects of photoreceptors on animal’s growth, immunity and homeostasis. Colors influence the efficiency of poultry performance and behavior. Light-emitting diode (LED) can use for providing monochromatic light source. In this trial, two hundred Ross 308 broiler chicks were studied in four different light groups as follows; White (Control), Red (RL), green (GL) and blue (BL) during 42 trial days. At the end of the study, the serum Superoxide dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx) and malondialdehyde (MDA) enzyme activities were measured to evaluate the oxidant-antioxidant balance. The oxidant marker MDA was found the highest value in group RL (p:0.0001 ; 9.24±0.33). On the other hand, in group GL, all antioxidant parameters were found the highest value (p<0.05). Also, SOD and GPx values were increased in group GL (SOD: 150.61±9.14 ; GPx: 186.96±10.50) than BL (SOD: 139.29±5.19; GPx: 160.02±3.15) statistically (p<0.05). The results showed that red light may be a stressor, and on the contrary, green light may be a positive monochromatic color for growth, oxidant-antioxidant balance and homeostasis for broilers

Determination of ceruloplasmin, some other acute phase proteins, and biochemical parameters in cows with endometritis

Aim: The aim of this study is to determine serum ceruloplasmin levels in cows with endometritis of varying degrees of severity and to establish whether or not there is a correlation between acute phase protein (APP) levels and biochemical parameters. Material and Methods: The study was conducted with 100 Brown Swiss cows (3-8 years of age) on days 28-32 postpartum. Cows were divided into endometritis (mild, moderate, and severe endometriosis) and healthy groups based on ultrasonography, vaginoscopy, and cytological examination. Blood samples were collected from all cows. Levels of haptoglobin (Hp), serum amyloid A (SAA), ceruloplasmin, albumin, and some biochemical parameters were analyzed. Results: Hp, SAA, and ceruloplasmin levels were higher in cows with endometritis than in healthy cows (p=0.001), and the levels of these APPs increased as endometritis became more severe (p=0.001). Some significant correlations were found between APPs and the biochemical parameters that were analyzed. In conclusion, it was determined that ceruloplasmin levels increase significantly in the presence of endometritis and proportionate to the severity of endometritis. A significant correlation was found between ceruloplasmin levels and Hp and SAA levels. Conclusion: It was concluded that ceruloplasmin levels can be used in the diagnosis of endometritis as an alternative to Hp and SAA levels

Serum paraoxonase activity and total sialic acid in sheep with foot and mouth disease

DEVECI, HACI AHMET/0000-0002-5613-0520;WOS: 000427048800011The aim of this study was to investigate paraoxonase (PON1) activity and total sialic acid to be measured for the first time in sheep infected naturally with foot and mouth disease, and their relationships with oxidative stress. A total of 30 Awassi sheep (aged between 2-4), which were healthy and infected with the foot and mouth disease virus (FMDV) were used in the study. Concentrations of paraoxonase activity (PON1), which is an important antioxidant against oxidative stress, high density lipoprotein (HDL) and total sialic acid (TSA), which has a critical role for immune system and is one of the significant indicators of cellular degeneration, were measured in serum samples drawn from animals. The total oxidant capacity (TOC) and total antioxidant capacity (TAC) were evaluated to determine the oxidative balance. It was observed that serum PON1 (P < 0.001) and HDL (P < 0.01) concentrations were significantly lower compared to the control group. TSA concentration was higher in the infected group (P < 0.001) compared to the healthy group. TOC was higher (P < 0.001) and TAC was lower (P < 0.01) in the infected group compared to the control group. Consequently, harmful effects of the infection of foot and mouth disease were shown as cause of oxidative cell damage and the high rate of sialic acid was produced depending on the degeneration during the infection

Carnitine concentrations in healthy and septicaemia suspected neonatal calves and its relation to passive immunty

Erdoğan, Hidayet Metin ( Aksaray, Yazar )This study was designed to determine carnitine concentrations in newborn calves with suspected septicaemia, healthy calves, and colostrum samples as well as to detect alterations in blood carnitine concentrations after colostrum intake. Carnitine concentrations were detected in both neonatal calves with suspected septicaemia (n = 195) and healthy calves (n =10) as well as in colostrum/milk samples from their dams (n = 20). The mean carnitine concentration on the 2nd day after colostrum intake (32.61 μmol/L) was significantly higher than that measured before colostrum intake (17.61 μmol/L) (P < 0.05). The striking result was significantly lower mean carnitine concentration detected in calves with suspected septicaemia (17.11 μmol/L), compared to healthy calves (24.92 μmol/L) (P < 0.001). Apart from a sudden increase on day 7, no significant alteration was observed in colostrum/milk carnitine concentrations throughout the postpartum period. The results indicated that colostrum contained carnitine, which passed into the bloodstream of the calf by passive colostral transfer, and that a dramatic reduction in blood carnitine concentrations of calves with suspected septicaemia existed. The results might be of help in dealing with septicaemia suspected neonatal calves through both measurement of blood carnitine and, in response, to supplement such cases with carnitine
