Effects of Newly Developed Synbiotic and Commercial Probiotic Products on The Haematological Indices, Serum Cytokines, Acute Phase Proteins Concentration, and Serum Immunoglobulins Amount in Sows and Growing Pigs - A Pilot Study.

Introduction: The aim of the study was to determine the effects of supplementation of sows' and growing pigs' diets with three newly developed synbiotic and two extant commercial probiotic products on selected immune parameters under field conditions.

Material And Methods: The study was performed on 30 sows and 48 piglets of the Danbred breed. Immune parameters such as concentration and proportion of white blood cells and their subpopulations, immunoglobulins amount in serum, and serum concentration of cytokines and acute phase proteins were recorded with the use of a haematology analyser and ELISA kits.

Pentachlorophenol from an old henhouse as a dioxin source in eggs and related human exposure.

High levels of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were detected in free-range eggs, and these levels reached a concentration of 29.84 ± 7.45 pg of WHO-TEQ/g of fat.

Immune response in pigs treated with therapeutic doses of enrofloxacin at the time of vaccination against Aujeszky's disease.

The effect of treatment with enrofloxacin was studied on the postvaccinal immune response in pigs. Forty pigs were used (control not vaccinated (C), control vaccinated (CV), vaccinated, received enrofloxacin (ENRO)). From day -1 to day 3 pigs from ENRO group received enrofloxacin at the recommended dose.

Immune and inflammatory response in pigs during acute influenza caused by H1N1 swine influenza virus.

Swine influenza (SI) is an acute respiratory disease of pigs, caused by swine influenza virus (SIV). Little is known about the inflammatory response in the lung during acute SI and its correlation with clinical signs or lung pathology. Moreover, until now there has been a limited amount of data available on the relationship between the concentrations of pro- and anti-inflammatory cytokines in the lungs and the serum concentration of acute-phase proteins (APPs) in SIV-infected pigs.

Cytokine and chemokine mRNA expression profiles in BALF cells isolated from pigs single infected or co-infected with swine influenza virus and Bordetella bronchiseptica.

Pigs serve as a valuable animal experimental model for several respiratory pathogens, including Swine Influenza Virus (SIV) and Bordetella bronchiseptica (Bbr). To investigate the effect of SIV and Bbr coinfection on cytokine and viral RNA expression, we performed a study in which pigs were inoculated with SIV, Bbr or both pathogens (SIV/Bbr). Our results indicate that Bbr infection alters SIV clearance.

Effect of maternal antibodies and pig age on the antibody response after vaccination against Glässers disease.

The influence of age and maternal antibodies on the development and duration of postvaccinal antibody response against Glässer's disease were investigated. Pigs born to immune (MDA-positive) and non-immune (MDA-negative) sows were vaccinated with inactivated vaccine. Vaccination was done according to three different protocols: at 1 and 4, at 2 and 5 or at 4 and 7 weeks of age.
