Rotavirus Diarrhea

ABSTRACT The aim of the present study was to characterize changes in acute phase protein levels according to the occurrence of rotavirus diarrhea in calves in the first month of life. Blood and fecal samples were taken before colostrum intake and at 1, 2, 7, 15, 21 and 30 days of age from 24 Holstein calves allotted in three experimental groups: calves that did not present diarrhea (group A), calves that presented diarrhea, but tested negative for rotavirus in feces (group B), and calves that presented diarrhea and tested positive for rotavirus in feces (group C) (experiment 1). When the animals presented episodes of diarrhea, blood and fecal samples were taken at 24-hour intervals until the end of clinical signs (experiment 2). Serum proteins were separated by SDS-PAGE technique and rotavirus in feces was detected by PAGE. Data of experiment 1 were analyzed by ANOVA and Tukey's test, considered significant at P<0.05. Data of experiment 2 were subjected to the HSD test. Total protein, globulins, and IgG concentrations were lower in group C than in groups A and B. Ceruloplasmin and transferrin levels were higher in group C than in groups A and B. Serum concentrations of haptoglobin and α1-acid glycoprotein did not differ significantly between groups throughout the experimental period. Calves presented diarrhea between 10.4 and 14.6 days of age in group B, and between 10.3 and 14.6 days of age in group C. In the moments of diarrhea manifestation, least square means of IgA, haptoglobin and α1-acid glycoprotein concentrations did not differ significantly between groups B and C, but ceruloplasmin and transferrin concentrations were higher in group C than in group B, as opposed to what occurred with IgG levels. These findings show that optimizing passive immunity transfer of immunoglobulins decrease the likelihood of calves developing diarrhea caused by rotavirus. In addition, ceruloplasmin presents characteristics of a biomarker of rotavirus infection in calves.

Abstract Calf bronchopneumonia is complex multifactorial disease and for its accurate diagnosis and therapy, besides clinical examination, microbiologic, hematologic and biochemical analyses could be necessary. In general, additional analyses are not implemented, mainly because the disease biomarkers are not defined. To establish which analysis might be useful for determining the severity of the disease, we analyzed 23 three-month old calves with mild clinical signs of bronchopneumonia and 15 age-matched healthy calves. Pasteurella multocida was isolated from deep nasal swabs of diseased calves. Peripheral blood erythrocyte and leukocyte count of bronchopneumonic and healthy calves showed no difference. Serum proteins, lipoproteins and lipids were analyzed with spectrophotometry, agarose gel electrophoresis, non-reducing SDS-PAGE, gel zymography, and thin-layer chromatography. The bronchopneumonic calves had an increased level of circulating immune complexes and α globulins, which contain some of the positive acute phase proteins. In diseased calves the increased concentration of total γ globulins (IgG), due to an increased concentration of anionic γ globulins (predominately IgG1), was detected. The increased concentration of anionic γ globulins followed by increased concentration of transferrin (negative acute phase protein) and HDL cholesterol, decreased concentration of LDL-cholesterol, unchanged activity of matrix metalloproteases and leukocyte counts might reflect the obvious absence of generalized inflammation. A positive correlation was found between the acquired results and the appearance of mild clinical signs. Therefore, we believe that the parameters analyzed in the peripheral blood could be applied as reliable disease markers to distinguish between severe (inflammatory) and mild forms of calf bronchopneumonia and to predict a better outcome for these calves.

One hundred 6- to 12-month-old Nelore calves were allotted into control group (G1; 50 healthy calves) and photosensitization group (G2; n= 50). Blood samples were collected 12 to 24 hours after the onset of dermatitis (M1), and 15 to 30 days after that (M2), at time of resolution of clinical signs. Serum protein electrophoresis was performed by means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Eighteen serum proteins with molecular weights ranging from 16,000 to 189,000 daltons (Da) were identified in all calves. In M1 and M2 serum concentrations of proteins with molecular weights of 115,000Da (ceruloplasmin), 61,000Da (a1-antitrypsin), 45,000Da (haptoglobin), and 40,000Da (acid glycoprotein) were significantly increased in calves. In conclusion, measurement of serum acute phase protein concentrations may be useful in monitoring the progression of bovine hepatogenous photosensitization, including guide probable alteration on therapeutic procedures.

ABSTRACT: Acute phase proteins (APP) are proteins synthesized and released largely by hepatocytes upon the occurrence of cell damage or invasion by microorganisms. This article reviews the use of APP in feline diseases, identifying their usefulness in the clinical setting, analyzing 55 published papers. Serum amyloid A, alpha-1 acid glycoprotein, and haptoglobin are the indicators pointed out by the authors as useful in monitoring the acute inflammatory response in cats. Although, APP measurement is still not routinely used in veterinary medicine, together with clinical signs and other blood parameters, was of clinical interest and applicability in diseases such as feline infectious peritonitis, pancreatitis, renal failure, retroviral and Calicivirus infections. Although, there are commercially available kits for dosing feline APP, assay standardization aiming technical simplicity, more species specificity and with less associated costs will allow routine use in feline practice, as it is done in the human field.

Abstract Aiming to define the evolution pattern of 10 acute-phase proteins in early infancy, we measured nephelometrically the serum concentrations of albumin, prealbumin, retinol-binding protein, transferrin, ceruloplasmin, hemopexin, haptoglobin, alpha 1-acid glycoprotein, alpha 2-macroglobulin, and alpha 1-antitrypsin in 395 term and preterm infants (gestational ages 26-41 weeks). Measurements were performed within 24 h after birth and then at the end of 1 (n = 171), 3 (n = 155), and 6 (n = 90) months afterwards. Data obtained from 250 healthy adults were used as adult reference values. All proteins increased progressively with postnatal age, except for alpha 1-antitrypsin, which remained stable from birth to the 6th month. Concentrations of almost all measured proteins were significantly lower in preterm than in term infants in the first 3 months. Compared with adult values, alpha 2-macroglobulin and alpha 1-antitrypsin were higher in infants throughout the 6 months. The other proteins were significantly lower at birth than adult values but after 6 months, only albumin, prealbumin, retinol-binding protein, and alpha 1-acid glycoprotein still remained lower in infants. Thus both gestational and postnatal age should be considered when interpreting concentrations of these proteins in early infancy.

Liver slices from normal rats and those suffering from inflammation for 24–48 h were incubated with L-[14C]leucine or D-[I4C]glucosamine. Immunological techniques coupled with radioautography indicated that the microsome fraction prepared from slices contained the subcellular site of synthesis of the polypeptide chain of serum albumin, and the polypeptide and carbohydrate chains of α1-acid glycoprotein; both proteins were also present in the medium in labelled forms. The contents of albumin and α1-acid glycoprotein in the medium and in extracts of liver from experiments with liver slices from control rats and 8–72 h experimental rats were determined using the quantitative precipitin technique. There was a net increase in synthesis of both proteins when slices from control and experimental animals were used, the increase showing up in medium proteins. However, slices from livers from 8–72 h experimental rats had a greater capacity for synthesis of α1-acid glycoprotein and a lower capacity for synthesis of albumin than slices from livers from control rats, the greatest changes occurring with slices from 24 h experimental rats. Changes in synthetic capacities of liver slices from experimental rats for albumin and α1-acid glycoprotein were always accompanied by large increases in specific radioactivities of total medium proteins when experiments involved incubation of slices with L-[3H]leucine and D-[14C]glucosamine. It is suggested that the increase in specific radioactivities of medium proteins following incubation of liver slices from experimental rats with labelled leucine and glucosamine is a characteristic of the response of liver to inflammation, and reflects changes in the capacity of liver for the synthesis of α1-acid glycoprotein and other acute phase serum proteins.

ABSTRACT Serum protein concentrations, including acute phase proteins (APPs), of goats and ewes with naturally acquired Sthaphylococcus aureus mastitis were determined by means of SDS-PAGE electrophoresis to evaluate the relevance of these APPs as biomarkers of the disease in these species. Fifteen healthy goats and 5 goats with naturally acquired staphylococci mastitis, as well as fifteen healthy ewes and 5 ewes with staphylococci mastitis were submitted to daily blood sampling during 7 days. In goats, an increase of 570%, 125%, 621%, and 279% in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein, respectively, was observed. In sheep the increase in serum concentrations of ceruloplasmin, fibrinogen, haptoglobin and α1-acid glycoprotein was of 337%, 90%, 461%, and 225%, respectively. Our results indicate that these APPs have considerable potencial as early and sensible biomarkers of mastitis caused by S. aureus in goats and sheep.

Inflammatory Processes

Stress occurs with the pressure of external and internal (infectious or non–infectious) causes which forces change in animals. This stress not only emerge with behavioral or clinical signs, but also will result with immune response formed by body. Understanding and evaluating this subclinic response is also possible with the help of Acute Phase Proteins (APP–AFP) which are released by tissues and organs when exposed to external and internal changes as well as known hormonal changes. Cattle are fed because of their economical importance and the inflammatory processes have influence on their yield levels. Because the stress is laying under all these health problems, also it is getting attention how stress effect the animals. Stress can be divided into main four groups: physical (mechanical), inflammatory (infectious), behavioral and other stress factors. The main APPs which all groups mostly using in their studies are serum amyloid A (SAA) haptoglobin (Hp), ceruloplasmin (Cp), fibrinogen (Fb), lipopolisakkarit binding protein (LBP) ve α1–Acid Glycoprotein (AGP).

The time-course of changes in the levels of albumin, α-fetoprotein (AFP), α1-protease inhibitor (α1-antitrypsin), α1-acid glycoprotein, fetuin, haptoglobin, transferrin, IgG and the major acute-phase protein (Pig-MAP) in the blood sera of pigs during the first days and weeks of life was investigated by quantitative radial immunodiffusion. The serum of newborn pigs before suckling was characterised by a very low concentration of total proteins (approximately 25 mg mL–1), low levels of albumin and transferrin and the lack of immunoglobulins. In contrast, α1-acid glycoprotein and fetuin are present at high levels (approximately 12 and 5 mg mL–1 respectively). The results of the present study show that the piglets undergo a very rapid metabolic maturation with regard to serum proteins, evolving from a characteristic ‘fetal’ pattern to an ‘adult’ one. We have paid special attention to the evolution of haptoglobin and Pig-MAP, which are two important acute-phase proteins in pigs. The evolution of serum levels of these proteins suggests that piglets must overcome a moderate acute-phase situation during the first week of life.

Serum concentrations of acute phase proteins can provide valuable diagnostic information in the detection and monitoring of disease. The available information on the acute phase response in cats with anaemia is limited. The aim of this study was to retrospectively evaluate serum concentrations of haptoglobin, serum amyloid A, α1 acid glycoprotein and their clinical importance in cats with anaemia. Thirty-four anaemic cats and ten healthy cats were enrolled this study. After individual diagnoses had been established, the cats were divided into three groups (healthy group, haemolytic group and non-haemolytic group). Serum acute phase protein concentrations were analysed using specific commercially available test kits in an ELISA reader device. Serum amyloid A and serum α1 acid glycoprotein concentrations were significantly higher in the anaemic groups compared with the healthy group. Haptoglobin concentrations were significantly higher in cats from the non-haemolytic anaemia group than they were in healthy animals and those from the haemolytic anaemia group. Although serum haptoglobin concentrations were lower than in the healthy group, there was no significant difference between the haemolytic anaemia group and the healthy group. The results of this study suggest that serum amyloid A and α1 acid glycoprotein could be useful in the diagnosis and determination of inflammation in cats with anaemia. Serum haptoglobin depletion may be used for diagnosis of haemolysis in cats with haemolytic anaemia. In addition, this study has contributed to the limited data available on acute phase protein concentrations in cats with anaemia..

Canine Ehrlichiosis

Early diagnosis of canine ehrlichiosis favors prompt institution of treatment and improves the prognosis for the animal, since this disease causes mortality among dogs. Studies have shown that determining the concentration of acute-phase proteins (APPs) may contribute towards early detection of disease and aid in predicting the prognosis. This study aimed to evaluate the APP profile in dogs experimentally infected with Ehrlichia canis, at the start of the infection and after treatment. It also investigated whether any correlation between APP levels and the clinical and laboratory alterations over the course of the disease would be possible. The results obtained showed abnormal levels of all the APPs on the third day after infection (D3), with the highest levels being reached on D18, with the exception of ceruloplasmin and acid glycoprotein, which presented their peaks on D6 and D12 respectively. We concluded that assessment of APP levels could contribute towards establishing an early diagnosis of canine ehrlichiosis, particularly regarding acid glycoprotein and ceruloplasmin, since these proteins were detected at increased levels even before the onset of clinical and laboratory findings of the disease.
