Levels of some trace elements and rheumatoid factor in sheep with brucellosis

Brucellosis is a zoonotic disease that is encountered in sheep rather frequently. In this study, 100 sheep diagnosed with brucellosis that had aborts and 40 healthy sheep were used as materials. Analyses for Cu, Zn, Fe, Cr, Ca, Mg, and K were performed with the atomic absorption spectrophotometric method on blood collected from vena jugularis of all the sheep and rheumatoid factor levels were determined by the nephelometry method. Although it was found that Cu, Ca, and rheumatoid factor values in the sera of the sheep with brucellosis were high when compared to the control group (p<0.001, p<0.05, p<0.001, respectively), their serum Zn values were low (p<0.05). No significant changes in serum Cr, Fe, K, and Mg levels were found.

Selected trace elements and esterase activity of carbonic anhydrase levels in lambs with pneumonia

The levels of, zinc, copper, Fe, Zn, Cu, Mn, Mg, K, Na, and Cl and the activity of carbonic anhydrase were determined in lambs with pneumonia. A significant decrease of p<0.01 level in Zn concentration, in Cu level (p<0.001) and significant increases in K and Na levels (p<0.05) and of the Cu/Zn ratio (p<0.001) were observed in the study group. The carbonic anhydrase activity was decreased in the study group, but the decrease was not statistically significant (p>0.05). Also, nonsignificant decreases of Fe, Mg, and Cl and increase of the Mn concentration were also observed in the lambs with pneumonia (p>0.05). Our results suggest that the significant element changes reported here and the Cu/Zn ratio, but not the activity of carbonic anhydrase, can be used as indicators of pneumococcal infection.

Evaluation of total antioxidant, total calcium, selenium, insulin, free triiodothyronine and free thyroxine levels in cows with clinical and subclinical ketosis

Absract: The purpose of this study was to evaluate serum albumin, glucose, calcium (Ca), cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), and phosphorus (P) in cows with naturally infected with Theileria annulata. The material of this study was a total of 15 cattle with different ages, breeds and genders diagnosed as theileriosis according to clinical and microscopical examination. According to statistical analyses of biochemical parameters; serum glucose, Ca, Co, Cu, Fe, Mg, and P concentrations were detected significantly low in cattle with theileriosis (P<0.001). In conclusion; mineral substance levels were altered in cattle naturally infected with Theileria annulata. Additionally to the classical treatment of theileriosis, administering mineral supplements including Ca, Co, Fe, Cu, Mg, and P to the animals is thought to be more useful in treatment.
