    Concentrations of serum amyloid A, haptoglobin, tumour necrosis factor and interleukin-1 and-6 in Anatolian buffaloes naturally infected with dermatophytosis
    (CZECH ACADEMY AGRICULTURAL SCIENCES, 2016) Kabu, M.; Sayin, Z.
    Dermatophytosis is most frequently found in ruminants, in which non-pruritic periocular lesions are most typical, though generalised skin disease may develop. Accordingly, the infection causes major economic losses. The aim of this study was to measure the inflammatory status of Anatolian buffaloes with dermatophytosis by determining the serum concentrations of serum amyloid A (SAA), haptoglobin (Hp), tumour necrosis factor (TNF-alpha) and interleukin-1 (IL-1) and -6 (IL-6). Anatolian buffaloes (n = 26), aged three to 11 month, were divided into two groups: 11 animals served as the clinically healthy control group and 15 animals clinically and microbiologically diagnosed with dermatophytosis formed the experimental group. Concentrations of tested proteins were measured using commercially available ELISA kits. In all cases, concentrations of measured proteins were significantly higher (P < 0.05) in infected animals when compared to healthy controls: SAA: 41.05 +/- 0.01 vs. 7.43 +/- 0.11 mu g/ml; Hp: 96.21 +/- 0.18 vs. 8.49 +/- 0.79 mu g/ml; TNF-alpha: 0.90 +/- 0.99 vs. 0.10 +/- 0.26 ng/ml; IL-1 alpha: 186.22 +/- 0.22 vs. 74.04 +/- 0.90 pg/ml; and IL-6: 55.94 +/- 0.50 vs. 32.45 +/- 0.20 pg/ml. It was concluded that the elevated values of variables under study were a result of the inflammatory response to dermatophytosis; thus, these markers may serve as an additional diagnostic tool.

    Diagnosis of Bovine Tuberculosis by PPD-ELISA and Sonication-ELISA
    (ISRAEL VETERINARY MEDICAL ASSOC, 2013) Sayin, Z.; Erganis, O.
    Mycobacterium bovis (M. bovis) infection in cattle remains a major zoonotic and economic problem in many countries. In addition, M. bovis is an important pathogen of both man and animals. The standard diagnostic test for this disease is the intradermal tuberculin test, one of the oldest immunological tests still in widespread use. However, this test can lack both sensitivity and specificity. Serological tests such as ELISA (Enzyme Linked Immunosorbent Assay) have been suggested as an alternative method for the diagnosis of tuberculosis. In the present study, two serum ELISA's, performed for the detection of M. bovis-specific antibodies, were evaluated against the culture of tissue samples from 135 slaughtered dairy cows, which were intradermal tuberculin-test-positive. ELISA plates were coated with Bovine Purified Protein Derivative (PPD B) and M. bovis-sonication antigen. Samples were taken from the bronchial (BLN), mesenteric (MLN) and prescapular (PLN) lymph nodes and tubercules (TB) of slaughtered cattle. Tissue samples were cultured in Lowenstein-Jensen medium. Blood samples, which were collected from the tuberculin-test-positive animals before slaughter, were tested by PPD B-ELISA (PPD-ELISA) and M. bovis sonication-ELISA (sonication-ELISA). Mycobacterium spp. was isolated from 77 out of 135 cattle. Out of 135 cattle, 62 (45.9%) and 43 (31.8%) were determined to be positive for PPD-ELISA and sonication-ELISA, respectively. Using culture-positive animals as a gold standard, the sensitivity and specificity of these two methods were detected as 48.2%-55.2% and 31.2%-44.5%, respectively.

    Haptoglobin and SAA Concentrations and Enzyme Activities in Bronchoalveolar Lavage Fluids From Calves With Bronchopneumonia
    (Ecole Nationale Veterinaire Toulouse, 2012) Coskun, A.; Guzelbektes, H.; Simsek, A.; Aydogdu, U.; Sayin, Z.; Sen, I.
    The aim of this study was to evidence acute phase response in bronchoalveolar lavage fluids (BALF) from calves with bronchopneumonia by measuring Haptoglobin and Serum Amyloid A (SAA) concentrations and some enzyme activities. For that, 30 calves with bronchopneumonia and 8 clinically healthy calves were selected on the basis of the clinical signs and examination and laboratory analysis. Haematological analysis (White Blood Cell counts) was performed using an automated haematology cell counter. In blood and BALF samples, gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activities and the total protein concentrations were measured using an automatic analyzer, whereas Haptoglobin and SAA concentrations were measured with commercially available ELISA kits. Proteinemia, GGT activity, haptoglobin and SAA concentrations in sera from diseased calves were significantly and dramatically increased compared to the healthy controls, while increases in other parameters (leukocyte count, ALP and LDH activities) were not statistically significant. Significant increases in LDH and GGT activities and in concentrations of the 2 acute phase proteins were also evidenced in BALF samples from calves with bronchopneumonia compared to the controls. In addition, except in 2 diseased animals, haptoglobin and SAA concentrations in BALF samples were above 250 and 25 mu g/L, respectively, whereas they have remained below the threshold values in all clinically healthy calves. These results show that BALF haptoglobin and SAA concentrations are useful acute phase proteins (APPs) for the determination of pulmonary inflammation in calves and future studies are needed to determine the importance of local acute phase response in the respiratory system.
