Opis:
The aim of the study was to assess the usefulness of real-time PCR and serological methods as indicators of postweaning multisystemic wasting syndrome (PMWS) occurrence. Significantly higher level of porcine circovirus type 2 (PCV2) viral load in serum and significantly lower titre of specific antibodies in PMWS-affected pigs indicated that combination of quantitative PCR and serological methods may support diagnosis of PMWS.

Opis:
Classical swine fever (CSF) is a notifiable, highly contagious disease of swine controlled mainly with costly administrative methods. Swine may be infected not only with classical swine fever virus (CSFV), but also with other, non porcine, genetically and antigenically related pestiviruses. Differentiation of infections with CSFV and other pestiviruses is a crucial element of diagnostics. In the present study two real-time PCR methods and conventional one-tube nested PCR for specific detection of CSFV were compared. Additionally, two methods designed for detection of all pestivirus species real-time SYBR Green I and one-tube nested PCR were included into the study. Analyzed methods varied considerably regarding their sensitivity and specificity, what suggests that careful selection of diagnostic methods and their evaluation on a regular basis is necessary.

Opis:
Introduction. COVID-19 is a disease caused by SARS-Cov-2 that has reached the pandemic status and has infected in one year more than 62 million people. Clinical symptoms range from barely noticeable to very severe. It is crucial to recognize imaging patterns of COVID-19, allowing for better diagnosis and treatment. Diagnostic imaging is also essential in monitoring patients in the course of the disease. Objective. In our pictorial review we describe the most common pulmonary manifestations of COVID-19, and show the typical and non-typical features of COVID-19 encountered in our hospital in Lublin, Poland. Imaging the disease progression is also visualized to help realize how pulmonary changes occur over the time. State of knowledge and Conclusions. COVID-19 involves both lung parenchyma and interstitium and has multiple imaging features, varying form ground glass opacities (GGO), consolidations, reticular interstitial pattern, honeycombing or crazy- paving. Mediastinal and hilar lymph node enlargement or pleural effusion may appear, but are rare and atypical. GGO are located peripherally, bilaterally and predominantly in the lower lobes, and in the early stage are better seen on CT imaging. Progression of imaging findings take different times, with the peak of of imaging features appearing around 10–14 days after initial symptoms. While it is harder to discern subtle changes on CXR, progression can be very well monitored by his method. Final pulmonary consequences of the disease should be assessed with the use of CT.

Opis:
The objective of the study was to evaluate an efficacy of sows vaccination protocols in the herd with serious problems affecting efficacy of reproduction. The study was performed in a large pig herd with about 1200 sows. Before vaccination against PCV2, farrowing rate in this farm was about 65%. Sows, boar and replacement gilts were immunized using Circovac vaccine (Merial, France) according to producer’s recommendations. Parameters of production were analyzed since 2007 until 2010 in selected batches of sows inseminated at the same weeks of the year (17th, 18th, 19th and 20th) to eliminate seasonal variability. In total, 940 sows were subjected to the study. No significant changes in management during these years were introduced. The applied protocol of sow herd long-term vaccination proved to be very efficient. All measured production parameters: reproduction rate, number of piglets born alive, birth weight of piglets and number of piglets weaned per a litter improved after implementation of immunization program. Moreover, further improvement was observed with vaccination in the following reproduction cycles. The most spectacular effect of vaccination regarded average farrowing rate that increased from 64.76% in control group to 86.93% after basic vaccination. Two years after implementation of vaccination program this parameter reached 93.6%. Number of piglets weaned per sow per a litter improved from 10.31 to 11.74 after one year of vaccination and remained relatively stable through the following year. Simultaneously, the percentage of newborn piglets with birth weight < 1 kg decreased significantly (p < 0.05). To summarize, vaccination against PCV2 influenced positively the insemination rate, number of piglets born alive and weaned per litter as well as birth body weight and percentage of piglets weighing < 1 kg.

Opis:
The aim of the study was to develop and validate real-time PCR method for the quantification of Lawsonia intracellularis and Brachyspira hyodysenteriae in porcine feces. Before the optimization process was performed two different extraction methods were compared to select the more efficient one. Based on the results achieved at this stage the boiling procedure was rejected and a commercially available silica-membrane based method was chosen for further analysis. The primers and the Taqman probe for B. hyodysenteriae and L. intracellularis were based on the sequence of NADH oxidase gene and 16S rDNA gene, respectively. The detection limit of the real-time PCR for suspension of feces inoculated with B. hyodysenteriae and L. intracellularis was determined to be 1.5x103 CFU/ml and 6.5x101 CFU/ml, respectively. The results of this study demonstrate that our real-time PCR is able to detect low number of B. hyodysenteriae and L. intracellularis cells which is satisfying in routine diagnosis of swine dysentery and proliferative enteropathy. Therefore, it is possible to identify both subclinically infected pigs and those representing an acute form of mentioned diseases. In summary, the quantitative real-time PCR is useful for routine diagnosis of L. intracellularis and B. hyodysenteriae. Compared to conventional PCR, the new validated quantification method based on real-time PCR is fast and with reduced risk of laboratory contamination. The novel technique is specific and even more sensitive than the previously used one. Furthermore, the new real-time PCR enables quick detection and quantification of both pathogens in fecal samples, which helps to estimate the health status of a pig herd.

Opis:
Za pomocą techniki PIV zmierzono i porównano prędkości kropel oleju w wodzie i prędkości wody w układzie jednofazowym. Badania przeprowadzono w mieszalniku zbiornikowym z mieszadłem Rushtona. Badania wykazały maksymalną różnicę w prędkościach rzędu 30% w okolicy mieszadła oraz porównywalne wartości szybkości dyssypacji energii. Przy niskich ułamkach objętościowych fazy rozproszonej, średnice kropel można przewidywać wykorzystując modele CFD dla układów jednofazowych.
Velocities of oil drops in emulsion and water in a homogeneous system were measured using PIV technique. Investigations were carried out in a tank equipped with the Rushton turbine. The maximum difference between velocities was observed close to the impeller and was equal to 30%. However, there was no difference in values of energy dissipation rate in both systems. For a low dispersed phase volume fraction, drop diameters can be predicted using CDF models for a homogeneous system.
