Since 2009, Poland has been recognised as a country officially free of bovine tuberculosis (bTB), although in each year of the last five there were from 8 to 18 outbreaks of the disease. In 2008–2016, the largest number of cattle infected with bovine mycobacteria were eliminated in the Masovian Province (the central region of Poland) and the largest number of outbreaks of this zoonosis were recorded in this area. The close proximity of farms where bTB was found led to the suspicion that tuberculosis could have been transmitted between the affected herds. The aim of the study was the molecular characterisation of the pertinent M. bovis/caprae strains and determination of the epidemiological relationship of various bTB outbreaks. The material for microbiological tests came from 119 cattle (Bos taurus) from nine herds located in five provinces, neighbouring the Masovian Province. Laboratory tests of tissue material gave results confirming tuberculosis in 54 (45%) animals. All strains belonged to the Mycobacterium bovis species. A two-step analysis of genetic affinity allowed 50 strains to be identified as phylogenetically closely related and separated between three genetic clusters consisting of 2 to 27 strains. Based on the results of genotyping, bTB outbreaks were found in three herds, and three transmission chains were identified among these herds.

Mobile phones (MP) and other electronic and communication devices that are used daily expose users to electromagnetic fields (EMF) and contribute to an increasing incidence of neurological disorders. Brain tissue is the closest organ to the MP as it operates, thus the influence of MP radiation on brain tissue is of particular concern, although research is still inconclusive. The present study investigated the possible effect of an EMF (1,350–1,375 megahertz (MHz)) from an MP on morphological and histopathological profiles in the mouse brain. Healthy BALB/c mice were assigned to three equal groups (a control and two experimental groups, n = 10 each). Experimental mice were exposed to EMFs continuously for 72 h, those of experimental group I to a 1,350 MHz field at a specific absorption rate (SAR) of 4.0 W/kg, and group II to a 1,375 MHz field EMF at an SAR of 4.0 W/kg. Brain segmentation and histopathological analysis were applied to detect changes in the morphometric parameters of the brain lobes and identify pathological lesions, respectively. Histopathology results revealed shrinkage of pyramidal neurons, presence of mild perivascular and perineural oedema, and some vacuolation of neurons and glial cells derived from mouse great hemispheres. The lesions also included reduction of Purkinje cells, vacuolisation of neurons and glial cells, and interstitial oedema in the cerebellum. MP distance of 3 cm from the cage may induce appreciable morphological changes in mouse brain structures; therefore, more comprehensive research is essential for assessment of safe distance. These pronounced effects may interfere with the results of laboratory tests on murine experimental models in veterinary or biomedical research.

In this study, the effects of three different ozonated oils (Sesame, Nigella sativa and Hypericum perforatum) on wound closure rate, healing process and possible complications were examined macroscopically and microscopically. Twenty-one adult Wistar albino female rats were used in the study. Subjects were divided into three groups, early wound healing, (7 days), medium wound healing, (14 days) and late wound healing (21 days). Four full-thickness skin wounds of equal size (10 mm in diameter) were formed on the back regions of all rats. This region was chosen for preventing self-inflicted injuries and reducing external irritation. The wound was left open during the healing process. While the first wound (control) received no treatment in the second wound, ozonated Sesame oil, in the third wound ozonated Nigella sativa oil and in the fourth wound ozonated Hypericum perforatum oil were used. No group obtained parenteral drug administration. First, second and third main groups were euthanized on days 7, 14 and 21, respectively. The wound healing was assessed macroscopically daily. Wound sizes of individual rats were measured with a caliper and digitally photographed every day from the day of injury. After euthanasia, all wound sites of the subjects were evaluated histopathologically.There were no significant differences in wound healing between treatments in the first day 7. On they 14, it was found that the healing was better in the group applied Nigella sativa and Sesame oils (p≤0.05). On day 21 wound healing was completed in all subjects with a resultant of better outcome in Nigella sativa oil treatment compared with others (p≤0.01).In this study the best wound healing outcome was achieved with Nigella sativa oil and Sesame oil where three different minced oils were used.

Wild rats are known as a major reservoir and intermediate host for several pathogenic microbial species. Thus, theVeterinary Research Institute (VRI) conducted a survey to determine the presence of parasitic pathogens in local rats, such as blood protozoans, gastrointestinal parasites, as well as ectoparasites such as mites and lice. The study was conducted with the collaboration of Kuala Lumpur City Council Pest Control Unit, whereby a total of 105 wild rats were trapped at two urban areas of Kuala Lumpur; namely PasarPudu and Chow Kit. Autopsy was done on the rats to acquire the skin, organ and blood samples..The skin scrapping was performed on skin samples to identify the common species of mites and lice, while the floatationtechnique was conducted on faecal samples to identify helminth eggs. Results showed thatspecies of Tritrichomonas, Strongyloides, Nippostrongylus, Blastocystis, Rodentolepis, Coccidia, Trichuris, Capillaria and Ascarid were found in the faeces while Trypanosoma sp.was found in the blood samples taken from the animals. Taeniataeniformis was obtained from liver samples while theectoparasites found on skin were identified as Radfordia,Polyplax,Linognathus and Hoploplurasp. Control and eradication of rodent pests is crucial in combating emerging and re-emerging diseases which may be zoonotic as rodents are reservoirs to various pathogens.

OBJECTIVE To compare results of point-of-care laboratory testing with standard veterinary clinical examination findings at a single time point during endurance competition to identify horses at risk for elimination. ANIMALS 101 endurance horses participating in the 2013 Western States 160-km (100-mile) endurance ride. PROCEDURES At the 58-km checkpoint, blood samples were collected from all horses. Samples were analyzed for pH, Pco2, base excess, anion gap, PCV, and whole blood concentrations of sodium, potassium, chloride, total carbon dioxide, BUN, glucose, and bicarbonate. Corrected electrolyte and PCV values were calculated on the basis of plasma total protein concentration. Immediately following the blood sample collection, each horse underwent a clinical examination. In addition to standard examination variables, an adjusted heart rate was calculated on the basis of the variable interval between entry into the checkpoint and heart rate recording. A combination of stepwise logistic regression, classification and regression tree analysis, and generalized additive models was used to identify variables that were associated with overall elimination or each of 3 other elimination categories (metabolic elimination, lameness elimination, and elimination for other reasons). RESULTS Corrected whole blood potassium concentration and adjusted heart rate were predictive for overall elimination. Breed, plasma total protein concentration, and attitude were predictive for elimination due to metabolic causes. Whole blood chloride concentration and corrected PCV were predictive for elimination due to lameness. Corrected PCV was predictive for elimination due to other causes. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that for horses in endurance competition, a combination of breed and clinical examination and laboratory variables provided the best prediction of overall elimination.

A preliminary study of nearinfraredreflectance spectroscopy (NIRS)for the feasibility of analytical monitoring ofamino acids and total protein compositionsin edible bird’s nest (EBN) was conducted.The training (n=134) and validation sets todevelop the equations were built with localunprocessed EBN samples sourced fromdifferent states of Malaysia. The regressionmethod employed was modified partialleast-squares (MPLS). The values ofstandard error for cross validation (SECV)and the coefficient of determination (r2)of the calibrations of these constituentsfor use to predict of amino acids in EBNwere determined, but with a low predictiveability. To find an acceptable accuracyfor each constituent is to increase thenumber of training samples. The findings,however, showed a potential alternativefor the implementation of near-infraredreflectance spectroscopy technology inthis field of analysis.

To investigate the possible effect of N-acetylcysteine (NAC) treatment on rat diabetes-induced liver damage and immune reactivity of asprosin hormone in the liver. Twenty-eight Wistar albino male rats were used in the study. They were separated into 4 groups as Control (n=7), Diabetes (n=7), Diabetes+NAC (n=7), and NAC (n=7). The rats in all groups were dissected after the treatment, and liver tissues were taken for pathological examination. Tissue sections were stained with immunohistochemistry for detecting asprosin immunoreactivity, hematoxylin-eosin and picrosirius red staining were performed to determine the changes in the tissues.In the microscopical examination of hematoxylin-eosin-stained sections normal histological hepatic tissues were seen in the Control and NAC groups. Pathological examination of liver tissue from diabetic rats showed marked dissociation, fibrosis, degeneration, inflammation, necrosis, Kupffer cells activation, bile duct proliferation, and congestion. A significant decrease in these lesions was observed in the DM+NAC group. Immunohistochemical studies showed that asprosin immunoreactivity was increased in the DM group in a significant manner. Asprosin expression was observed to be significantly reduced in the DM+NAC group in comparison to the DM group.Our findings show that NAC administration reduces liver damage in diabetic rats and can be used to reduce/eliminate the negative effects of diabetes in rat liver tissue..

This study was conducted with the purpose of investigating the distribution of the Activating Transcription Factor 6 (ATF6) and the Nerve Growth Factor (NGF) in the duodenum tissue of diabetic and non-diabetic rats. Eighteen female Sprague dawley rats were randomly divided into three groups as thecontrol, sham and diabetes groups. Routine histological and immunohistochemical methods were appliedon the duodenum tissues collected at the end of the study.Results: It was determined that the villus length measurements showed a statistically significant differencebetween the control and diabetes groups. There was NGF immunoreactivity which was moderate anddiffuse cytoplasmic in the villus intestinalis and muscularis layer in all groups, weak in the crypts andglands in the control and sham groups and moderate and diffuse cytoplasmic in the diabetes group. ATF6immunoreactivity was determined moderate in the villus intestinalis, crypts, glands and muscularis layerin the control and sham groups and strong diffuse cytoplasmic in the diabetes group. It wasdetermined that both NGF and ATF6 immunoreactivity increased in the duodenum tissue of the rats onwhich diabetes was induced experimentally.

A total of 23,322 specimens collected between 2014 and 2017, froma total of 2,592 cases, were received in Veterinary Research Institute, Ipoh (VRI) from various states in Malaysia and testedfor common bacterial, viral, and parasitic diseases in pigs. The highest occurrence of isolated bacteria from 771 samples whichtested positive were Salmonella (47.38%) and Escherichia coli (15.68%), followed by Staphylococcus (6.62%), Streptococcus (5.57%), Klebsiella pneumonia (4.88%), Pseudomona (3.38%), Acinetobacter (3.14%), Aeromonas (2.79%), Enterobacter (2.44%), one each of Bacillus and Pasteurella multocida (1.74%), Enterococcus (1.39%) and Corynebacterium (1.05%). 1.74% of each bacteria detected were Moxarella, Aspergillus, Burkholderia andChromobacterium. Positive samples tested by ELISA was Japanese encephalitis virus (JEV) (9.15%), Aujezsky disease virus (ADV)(5.37%), porcine cirvo-virus-2 (PCV2) (5.09%) and porcine reproductive and respiratory syndrome virus (PRRSV) (4.52%). Positive amples tested by the molecular test wasPCV2 (1.62%), PRRSV (1.32%) and classical swine fever virus (CSFV) (0.4%). Serology tests were conducted on 11,305 samplesand reported positive for Brucella suis (15.32%), Brucella abortus (0.62%), Brucella melitensis (0.85%), and melioidosis (0.05%). Parasitology analyses on 99 samples. revealed presence of 10.1% coccidia and 1% each of helminths and Sarcocystis. Within the 4-year period, there were no positive samples for porcine parvovirus (PPV), Nipah virus, swine influenza virus (SIV), and bacteria of Johne’s disease and leptospirosis. Continuous assessment is required to establish a comprehensive baseline data of swine diseases in Malaysia.

The objectives of the present study were to determine if diagnosis and treatment of equine pituitary pars intermedia dysfunction (PPID) vary by geographic region and to report the prevalence of PPID in horses as observed by veterinarians across locations. An online questionnaire was developed for veterinarians who treat horses. Veterinary associations, especially equine specialty subgroups, were contacted and a survey link was sent to members of each organization. Generalized linear models were used to examine whether the method of diagnosis and treatment of this condition, as well as its reported prevalence, differed by geographic region. Veterinarians from 426 separate clinics in 20 countries returned surveys. Diagnosis of PPID varied by region, but was usually based on clinical signs and an adjunct endocrine test. Horses with PPID were treated medically by 63% of veterinarians and 75% of these used pergolide mesylate as treatment. The median prevalence estimated was 1% and this did not differ by geographic location. Half the veterinarians were caring for 5 or more animals with PPID. Overall, diagnostic approach differed in geographic regions. In general, European veterinarians were more likely than those in North America to diagnose PPID based on clinical signs alone, without using an adjunct laboratory test. Veterinarians reported that cost and management responsibilities were their clients' primary concerns associated with the long-term treatment of this disease, which indicates a need for additional treatment options for PPID.
