It is endemic in many parts of the world, but there are areas and countries that have successfully eradicated this disease. Due to mandatory control measures and trade barriers, Aujeszky's disease causes significant economic losses. Although, it has been eradicated in most European Union Member States, there are still areas and countries where it persists. In the Republic of Croatia, the disease has not yet been eradicated from the domestic pig population, although surveillance and eradication has been carried out since 2013. This paper presents the results of serological testing of domestic pigs for Aujeszky's disease in the period from 2013 to 2021. The prevalence of Aujeszky's disease at the farm level by year in the study period ranged from 4.66% (CI 95%, 4.39-4.95) to 0.67% (CI 95%, 0.35-1.28). Since 2016, prevalence was at an average level of 1.26% (CI 95%, 0.67-1.95%). The highest prevalence 10.28% (CI 95%, 9.15-11.53) was found in Varaždin County, and the lowest 0.14 % (CI 95%, 0.07-0.31) in Krapina-Zagorje County.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43797290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Muški je reproduktivni sustav jedno od najosjetljivijih tkiva na RF-EMZ-e.

{"title":"Entropy and its significance in transport of ions through the cell membrane","authors":"Selim Pašić, Nato Popara, Antea Klobučar, D. Cvitković, M. Vilić","doi":"10.46419/vs.54.5.8","DOIUrl":"https://doi.org/10.46419/vs.54.5.8","url":null,"abstract":"The aim of this paper is to present the concept of entropy in a simple way and to show its key importance in the transport processes of ions through the cell membrane using the latest discoveries in biophysics. Using a real-life example, we show how processes within a system lead to an increase in entropy. We also show how this entropy increase is directly related to the irreversibility of the process, and how it defines the arrow of time (direction of the flow of time). Using an abstract example, we clarify the meaning of the concept of disorder in a system, which is often used in defining entropy by connecting it with the number of microstates that realise a macroscopic state of a system. The importance of entropy in transport processes of ions through the cell membrane is considered. We show that passive transport processes through the cell membrane are the result of an entropy increase in the cell membrane-transported substance system. A model of active ion transport through the cell membrane following Rubi et al. (2017) is presented. The force that transports ions through the channel in the transport protein arises due to the entropy gradient formed along the transport channel, which is a consequence of the funnel shape of the channel. The entropic force is proportional to the ratio of the ion-available cross-sections of the exit and entrance surface of the channel. That means that only a very funnel-shaped channel can produce a sufficiently large force on the ions to overcome the concentration gradient of the substance. We analyse the final result for the force of entropy in the limits of a very wide and very narrow channel and find that the entropic force is proportional to the ratio of the areas of the exit to entrance surfaces of the channel, i.e., when the channel is very wide, while it becomes high as the width of the channel tends to the ion diameter, i.e., when the channel is very narrow. We explicitly explain how the presented model solves several fundamental questions about the active transport of substances: how is energy, a scalar quantity, converted into the directional motion of the ion (a vector quantity), how does energy drive ions considering that the point of release of energy is far from the point of binding of an ion in a transport protein and finally, how does energy, which is released in a very limited space, transport the ions over a very large spatial scale.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45884289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pasteurellosis, caused by P. multocida, is regarded as one of the most important bacterial diseases of rabbits. The disease is characterised by chronic mucopurulent respiratory affection (snuffles) or more acute and subacute bronchopneumonia leading to high mortality and severe devastating losses in rabbit production. Moreover, pasteurellosis is associated with septicaemia, abscesses, otitis media, and nervous and reproductive disorders. P. multocida is widely distributed worldwide and mostly affects rabbits from 4 to 8 weeks of life. Infection with P. multocida usually occurs by indirect or direct contact, chiefly via aerosol. Moreover, the presence of other stressors can aggravate the severity of infection. The gold standard for the diagnosis of pasteurellosis is traditional isolation and identification methods. However, molecular techniques are used now for rapid detection of P. multocida and its virulence genes. Prevention is based on the application of hygienic methods, vaccination, and treatment using various antimicrobials. This review article gives an overview of pasteurellosis in rabbits regarding disease incidence, susceptibility and transmission, signs and lesions, laboratory diagnosis, and the prevention and control methods.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47212182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arthropods were less abundant and species rich in swallow nests than in pigeon or stork nests, where a greater dominance of mesostigmatic mites (78.71% and 72.41%, respectively) was found. Dermanyssus gallinae was the most abundant (33.05%) and most frequent (73.33%) mesostigmatic mite in pigeon nests, while uropodina mites were dominant (41.37%) in white stork nests with a frequency of 76.92% of the nests analysed. In swallow nests, the following arthropods were found: Psocodea, Hemiptera, Hymenoptera and Coleoptera belonging to the class Insecta and Isopoda belonging to the class Malacostraca. This is the first comparative survey of arthropods occupying the nests of these bird species in northern Algeria. It is anticipated that these data, that highlight the richness of the arthropod fauna in the nests of these bird species, will motivate further research aimed at characterising the arthropod community in different bird nests and determining the nature of the relationships between them.","PeriodicalId":23596,"journal":{"name":"Veterinarska stanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41742041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to test the improvement of PFT in mice lung fibrosis induced by treatment with an approved substance nintedanib, considered the gold standard. The hypothesis that treatment in animal models will demonstrate similar effects as in humans in the most relevant clinical outcomes was tested. Two experimental designs were enrolled in this study, a preventive regimen, with treatment initiation from the day of the challenge; and a therapeutic regimen, starting on day 7 postchallenge when fibrotic changes are present in the lungs. Experiments were terminated at two different time points, at 14 and 21 days postchallenge. C57BL/6 mice were administered with bleomycin (BLM) intranasally and treated with nintedanib from day 0 to day 14 or from day 7 until day 21. Fourteen or 21 days after the BLM challenge, PFTs were assessed using the in vivo invasive lung function measurement system Buxco® Pulmonary Function Test (PFT) (DSI™, New Brighton, USA). Histological evaluation was performed as a modified Ashcroft score. The bleomycin challenge induced a significant decrease of FVC in both experiments. However, nintedanib treatment given in both regimens significantly improved lung functionality. These findings were confirmed with histological analysis of the Ashcroft scoring system, modified by Matsuse. In conclusion, a good correlation between functional test parameters and the clinical effect of nintedanib was shown in both experiments: the preventive regimen was sampled 14 days post-challenge and the therapeutic regimen 21 days post-challenge.
