The influence of probiotic administration on selected leukocyte subpopulations and the serum amyloid A concentration in the peripheral blood of dairy cows during different lactation periods.

Introduction: The aim of the study was to compare selected leukocyte subpopulations and the serum amyloid A (SAA) concentration in the peripheral blood of cows at different stages of lactation. The blood of cows receiving a probiotic as a dietary supplement was compared with the blood of cows not receiving it.

Material And Methods: The research was conducted on 20 pregnant dairy cows randomly divided into two groups of 10 cows each.

The influence of probiotic administration on the phagocytic and oxidative burst activity of neutrophils and monocytes in the peripheral blood of dairy cows during different lactation periods.

Introduction: The objective of this bovine peripheral blood study was a comparative assessment of the phagocytic activity of neutrophils and monocytes and of the intracellular killing capacity of neutrophils from cows given no probiotic and from cows which were administered a probiotic consisting of and . These activity types were compared during different lactation periods.

Material And Methods: A cohort of 20 pregnant dairy cows was divided into two groups of 10.

The diagnostic value of selected immune parameters in peripheral blood of dogs with malignant mammary tumours - a preliminary study.

Introduction: The main adaptive immune cells are T and B lymphocytes and they play key roles in the induction of immune responses against canine mammary tumours. Investigating these cell subpopulations may lead to more precise diagnosis of these malignancies.

Material And Methods: The percentages of CD3, CD4 and CD8 T cells and of CD21 B cells in the peripheral blood of bitches with malignant mammary tumours were compared with those in the blood of healthy animals.

Cytokine inflammatory response in dairy cows with mastitis caused by .

Introduction: The aim of the study was evaluation of the concentrations of interleukin (IL)-1β, IL-8, IL-12β and tumour necrosis factor alpha (TNF-α) in the serum and milk of cows with mastitis caused by .

Material And Methods: A total of 60 milk samples from diseased cows and 30 milk samples from healthy cows were included in the study. Blood and milk samples were taken from Holstein-Friesian cows from three herds (two in tie-stall and one in a free-stall housing system) in Lublin Province in Poland.

Plasma levels of chemokines CCL2 and CXCL12 in female dogs with malignant mammary gland tumours without and with metastases.

The aim of this study was to evaluate the plasma levels of chemokines CCL2 and CXCL12 in female dogs with malignant mammary gland tumours without and with metastases. The concentrations of CCL2 and CXCL12 were determined in 25 female dogs with malignant mammary gland tumours (15 without metastases and 10 with metastases) and 10 healthy control animals using a specific canine ELISA assay. The mean plasma concentrations of CCL2 and CXCL12 were significantly higher (p<0.
