Coagulation profile, haematological and biochemical changes in kids naturally infected with peste des petits ruminants.

The aim of this study was to examine the coagulation profile in peste des petits ruminant (PPR) in kids. Five kids from a group of 150 animals (72 goats and 78 kids) were brought to the Veterinary Medical Teaching Hospital from a farm in Burdur province (Turkey) with nasal and ocular discharges and diarrhea. Fifteen goats and 41 kids had died due to diarrhea and three kids were presented to the Department of Pathology for diagnosis. Blood samples were taken from 12 ill animals (infected group) for haematological and biochemical analysis. In addition, five healthy kids were examined from another healthy flock (control group). Leukocyte and lymphocyte numbers of infected group showed significant declinations in comparison to control group (≤0.001). Haemorrhages in all organs of digestive system and small haemorrhagic areas in liver were caused to decrease in erythrocyte and haematocrit values (p ≤ 0.001) in infected group. Concentrations of blood urea nitrogen (BUN) (p ≤ 0.01) and creatinine (p ≤ 0.001) in infected group were significantly higher than control group. Compared to control group, significant increases were determined in serum concentrations of alkaline phosphatase (ALP) (p ≤ 0.01), aspartate aminotransferase (AST) (p ≤ 0.001) and alanine aminotransferase (ALT) (p ≤ 0.001) in the infected group. No significant differences were observed between the infected and control groups for serum gamma glutamyl-transferase (GGT) concentration value. In our study, thrombocytopenia (p ≤ 0.001) together with prolonged activated partial thromboplastin time (APTT; p ≤ 0.01) and prothrombin time (PT; p ≤ 0.001) may show that disseminated intravascular coagulopathy which can occur in kids with PPR.

Evaluation of changes in serum lipoprotein and apolipoprotein patterns in cows with ketosis.

OBJECTIVE: To detect changes in serum lipoprotein and apolipoprotein profiles via precipitation and electrophoresis in ketotic cows and in those cows treated with different methods. ANIMALS: 21 cows with clinical and subclinical ketosis, 7 healthy cows in the early lactation period, and 7 healthy cows in the nonlactation period. PROCEDURES: Ketotic cows were allocated into 3 groups; the first group was treated with dextrose and dexamethasone, the second group with dextrose and prednisolone, and the third group with dextrose and insulin. The beta and alpha lipoproteins were precipitated with dextran sulfate-magnesium chloride in ketotic cows after treatment and healthy cows in the nonlactation and lactation periods. The serum samples, precipitates, and supernatants were examined via agarose gel electrophoresis for detection of alterations in serum lipoproteins. Subsequently, alterations in serum apolipoproteins were detected via SDS-PAGE of precipitates. RESULTS: Compared with serum beta and alpha lipoprotein concentrations in healthy cows during nonlactation, those in cows during lactation were higher; however, those in cows with ketosis were lower. The SDS-PAGE analysis of serum beta lipoproteins revealed that apolipoprotein E (approx 36 and 40 kDa) decreased in ketotic cows, in comparison with healthy cows in the nonlactation and lactation periods, but increased after treatment. Decreases in apolipo-protein B (approx 222 kDa), apolipoprotein A-I (19 and 24 kDa), apolipoprotein A-IV (55 kDa), apolipoprotein C-III (8.8 and 10.2 kDa), and albumin (66 kDa) concentrations were detected in ketotic cows, in comparison with the healthy cows in the lactation period. CONCLUSIONS AND CLINICAL RELEVANCE: Serum lipoprotein and apolipoproteins may routinely be determined via precipitation and electrophoresis in the diagnosis and treatment of ketosis.
