COMPARATIVE PATHOMORPHOLOGICAL ANALYSIS OF CHANGES IN DOGS AND CATS CAUSED BY INOCULATION OF A VACCINE STRAIN AND FIELD ISOLATES OF AUJESZKY’S DISEASE VIRUS

Vasil Manov

ABSTRACT

The great sensitivity of carnivorous animals to the Aujeszky’s disease virus makes them an indicator of the presence or absence of the causative agent on a farm. The massive spread of rodents and especially cats, from porcine industrial farms with reproductive disorders, is the reason to investigate the clinical manifestations and pathomorphological changes induced by the vaccine strain and two terrain uterotropic strains of the Aujeszky’s disease virus in dogs and cats. Kittens of 50–60 and dogs at 35–40 days of age were used. It was found that strain Mogila was highly virulent for dogs and cats, and the vaccine strain was more pathogenic for dogs and less pathogenic for cats. Cats had no itching. Pathohistological changes were localised in the nervous and respiratory system. They have the character of nonsuppurative encephalitis and interstitial pneumonia. In the lungs of cats, infected with strain Mogila, a fibrinous-necrotizing inflammatory response was observed.

PATHOMORPHOLOGICAL STUDIES IN NEWBORN PIGS INDUCED BY INFECTIONWITH VACCINAL STRAIN МК 35GE- AND FIELD ISOLATES MOGILA AND ST. ZAGORA OF SUID HERPESVIRUS 1. PART I. NERVOUS SYSTEM

Vasil Manov

ABSTRACT

The purpose of the present study was to perform a comparative morphological analysis of the changes in the central nervous system of new-born pigs prior to colostrum intake. The infection was artificially created by application of a vaccine strain MK 35gE- and two strains, isolated from intrauterine infection cases – Mogila and Stara Zagora II. A restriction profile of the viral strains was made. No neurological signs or 100% mortality were registered in the pigs that were infected with the strains St. Zagora II and MK 35gE-. Pathohistological changes caused by these two strains of the virus in animals CNS were similar and were characterized primarily by reproductive problems. The pathological changes induced by Mogila strain were obvious by presence of alteration, exudation, and proliferation (less pronounced) in the brain.

EFFECT OF ZINC-COPPER HYDROCHLORIDE MIXED CRYSTALS APPLICATION IN RABBITS WITH ACUTE EXPERIMENTALLY INDUCED FASCIOLOSIS

V. Nanev, N. Tsocheva-Gaytandzhieva, M. Gabrashanska

ABSTRACT

Effects of zinc (Zn) – copper (Cu) hydroxochloride mixed crystals were tested on body weights, body weight gain, mortality, liver vitamins A, C, E, trace elements Zn and Cu and enzyme Cu-Zn superoxide dismutase. Investigated parameters were not changed significantly compared to controls in Zn-Cu hydroxochloride mixed crystals supplemented rabbits. Body weights and body weight gain were reduced, mortality was increased and liver biochemical parameters were decreased in F. hepatica infected animals. All affected parameters were increased near to controls after Zn-Cu hydroxochloride mixed crystals application in infected rabbits, so they may be used for restoration of disturbances from fasciolosis.

ELECTROCHEMICALLY ACTIVATED AQUEOUS SOLUTIONS – ESSENCE, ACTION AND SOME ASPECTS OF APPLICATION

Toshka Petrova, Teodora Popova

ABSTRACT

The main characteristic of the electrochemically activated aqueous solutions“ (ECAAS) is that if they are subjected to unipolar electrochemical influences with certain characteristics, in them occur metastable, i. g. electrochemically activated substances giving them unique ecological, chemical, physical, biological and, in particular, microbiological properties, which all the currently authorized chemicals (biocides, cosmetics and pharmaceuticals) do not possess. The anolyte and has reduced electron activity and pronounced oxidant properties, and the catholyte has enhanced electron activity and reductor properties.Because of their low oxidant content, the anolytes have very little chemical buffering, hence their environmental safety. The qualities of the ECAAS have provided grounds for their broad application both in the human and in the veterinary field, in the military field, the food industry, for the disinfection of ships, wagons, airplanes, etc. We conducted tests to determine the effect of an anolyte containing Cl obtained by electrochemical activation of sterile distilled water with 3% NaCl on depleted sludge from a municipal wastewater treatment plant, on bovine manure and on Clostridium perfringens. The results show that the anolyte added in equal proportion to the manure resulted in a reduction in the total number of microorganisms 20 times (2.6×105 CFU/ml) compared to the untreated control manure (7.5×106 CFU/ml), and upon addition of a doubly lesser amount of anolyte, the total number of microorganisms decreased 10 fold (4.5×105 CFU/ml) relative to the control. After 24 hours influence of anolyte on depleted sludge, there was a decreasing in the amount of microorganisms from all the groups studied. The decreasing was statistically significant in the total number of microorganisms and that of the Gram-negative aerobes in comparison with the untreated sludge, more significant in the sludge treated with equal quantity anolyte than that, treated with twice smaller amount of anolyte. The anolyte added in equal amounts to a suspension of C. perfringens at a density of 2.0×106 CFU/ml after 10 minutes of exposure, caused a three-fold decrease in the amount of viable cells in the suspension.

EFFECT OF А PURIFIED SAPONINS’ MIXTURE FROM ASTRAGALUS GLYCYPHYLLOIDES, ADMINISTERED ALONE, ON ISOLATED RAT BRAIN SYNAPTOSOMES AND HEPATOCYTES

Georgi Popov, Magdalena Kondeva-Burdina, Vasil Manov, Aleksandar Shkondrov, Ilina Krasteva

 ABSTRACT

            Purified saponins’ mixture (PSM), obtained from Astragalus glycyphylloides (family Fabaceae) was examined for possible toxic effects on isolated rat brain synaptosomes and hepatocytes when administered alone. Synaptosomes and hepatocytes were incubated with PSM at three different concentrations: 60 µg/ml; 6 µg/ml; 0.6 µg/ml. The effects of PSM were compared to those of silymarin, in the same concentrations. The main parameters, characterizing functional and metabolic status of synaptosomes and hepatocytes were investigated: viability (by Trypan blue – for hepatocytes and MTT-test – for synaptosomes), lactate dehydrogenase activity (LDH), level of reduced glutathione (GSH) and production of malondialdehyde (MDA). It was found that administered alone the PSM did not reveal any statistically significant toxic effects on both isolated rat brain synaptosomes and hepatocytes, compared to silymarin

STUDY ON INTERNAL PARASITES IN SNAKES GROWN IN DOMESTIC CONDITIONS

Seven Mustafa, Radoslav Rafailov, Kostadin Kanchev, Constantinos Koureas, Maria-Ioanna Manioti

 ABSTRACT

Parasitological study of domestic snakes is a diagnostic approach of great veterinary significance, as many of the internal diseases have similar clinical signs. With modifications of our known diagnostic methods, a number of internal non-infectious diseases can be differentiated from parasitoses or appropriate corrective measures can be identified in breeding conditions. Domestic snakes have been investigated, with some being found to contain oxirid eggs. A study on this finding was carried out and methods of investigation, parasitosis data and procedure for treatment were pre-sented, with commenting on the importance of oxyuridosis in serpents. It is necessary to emphasize the importance of a periodic prophylactic control of the parasitological status of domestic snakes as a preventive measure against diseases, which is of great importance for the breeders and the pet shops because there is a gathering of animals and an exchange of inventory.

OUTBREAK OF INFLUENZA A VIRUS (H5N1) IN DALMATIAN PELICANS SREBARNA RESERVE, BULGARIA, 2015

Georgi Stoimenov, Gabriela Goujgoulova, Kalin Hristov, Atanaska Teneva

ABSTRACT

           On March 25, 2015, a highly pathogenic avian influenza viruses were isolated from the carcasses of a 3 Dalmatian pelicans (Pelecanus crispus) in Bulgaria. Polymerase chain reaction (PCR) and H5N1-specific real-time reverse transcription polymerase chain reaction (rRT-PCR) analysis showed, that the H5 and N1 avian influenza virus was presented in the lung, trachea, proventriculus, cloaca and brain tissue of the dalmatian pelicans. Subsequent sequence analysis found the following motif of basic amino acids at the cleavage site of hemagglutinin: PQRERRRKRGLF, which is characteristic of highly pathogenic avian influenza viruses. Phylogenetic analysis of a part from segment 4 of A/dalmatian pelican/ Sreburna/Bulgaria/2015 (H5N1) showed a close genetic relationship with influenza viruses A (H5N1) clade 2.3.2.1. Тhe establishment of HPAI H5N1 in 2015, belonging to the genetic clade 2.3.2.1, circulating in Southeast Asia and in Bulgaria for the second time since 2010, shows the great potential for the trans-continental distribution of the virus and its ability to cause not only epizootic outbreaks, but also panzootic waves.

ABSTRACT

This study was focused on changes of some minerals and blood metabolites during experimentally in-duced H. contortus infection in lambs. A total of 12 animals were included in the study and were divided into experimental (n=6) and control (n=6) groups. The lambs from experimental group were orally inoculated with 4000 infective H. contortus larvae (L3) by placing a probe. Blood parameters (calcium, phosphorus, magne-sium, creatitine, glucose, total bilirubin, urea and alkaline phosphatase) were monitored on post infection days 0 and 21. The most pronounced changes occurred in urea and alkaline phosphatase levels, which increased significantly on day 21 (p<0.05) and reached values of 12.17±0.24 mmol/L and 334.17±32.3 U/L, respectively. The concentration of urea in experimental group was higher by 46.82% compared to control group. Alkaline phosphatase activity was also increased by 55.07% vs. control group. Mild changes occured in plasma concentrations of calcium, phosphorus, magnesium, creatinine, glucose and total bilirubin but were not considered significant throughout the experiment.

Bogdan Aminkov, Nikolay Mehandzhiyski, Konstantin Aminkov, Ilia Peev

ABSTRACT

The present study was conducted to define the physiological responses of captive brown bears (Ursus arctos) immobilized by standardized total intravenous anesthesia protocol (TIVA), during routine health check. Hematology and biochemistry parameters (WBC, Lymph, Mon, Gran, Lymph%, Mon% Gran% RBC, HGB, HCT, PLT, ALT, AST, ALP, GLU, TP, ALB, UREA, CREAT, GLB) were evaluated in nine brown bears, anesthetized with total intravenous anesthesia protocol for ninety minutes during the health check. The animals were kept in the „Park for Dancing Bears“ Belitza, Bulgaria. A standardized premedication protocol of tiletamine HCl and zolazepam HCl (Zoletil 100® Virbac, France) at 1 mg/kg, medetomidine HCl at 0.003 mg/kg (3 mcg/kg) and butorphanol tartrate at 0.05 mg/kg (50 mcg/kg) administered intramuscularly. Anesthesia was induced intravenously with a combined bolus of ketamine at 2 mg/kg and propofol at 2 mg/kg, and maintained with a constant rate infusion (CRI) of ketamine at 0.8 mg/kg/h and propofol 0.04 at mg/kg/min. Overall results compared to baseline levels did not present statistically significant changes, to the exception of PLT, GLU, and CREAT. In conclusion, the research anesthetic protocol is an inexpensive and relatively safe method for various manipulations and procedures in the brown bear.

ABSTRACT

The aim of the present investigation was to evaluate the toxic effects of aflatoxin B1 on pancreas morphology. Also, the possibility for prevention of toxic effects of AFB1 by feed supplementation of a mycosorbent (Mycotox NB) was studied. Experiments were carried out with 60 7-day-old female turkey broilers (meat TM strain) divided into one control and five treatment groups (n=10): Group I – control (0 mg/kg AFB1 not supplemented with Mycotox NG); Group II (0.5 g/kg Mycotox NG), Group III (0.2 mg/kg AFB1), Group IV (0.4 mg/kg AFB1), Group V (0.2 mg/kg AFB1 and 0.5 g/kg Mycotox NG) and Group VI (0.4 mg/kg AFB1and 0.5 g/kg Mycotox NG). The duration of the experiments was 42 days. Histopathologically, the pancreatic changes in turkey broilers treated at 0.2 mg/kg AFB1 comprised generalised vascular hyperaemia, interlobular oedema, initial disorganisation and disintegration of glandular acini. Birds treated at 0.4 mg/kgAFB1 exhibited complete glandular acini disorganisation, haemorrhages mononuclear cell infiltrations as well as necrobiotic changes. The supplementation of the feed of groups V and VI with the tested toxin binder reduced the severity and frequency of observed histological lesions (slight interlobular oedema, the disintegration of acinar cells was insignificant and initial granular dystrophy of the cytoplasm of Langerhans islet cells).

Ivan Fasulkov, Manol Karadaev, Nasko Vasilev, Martin Nikolov, Tsvetelin Nonov

ABSTRACT

The purpose of this study was to investigate the possibility of visualization and characterization of the mammary glands structures in lactating cows through 3D ultrasonography. Ten Black-and-white cows, 5 years of age, weighing 380–450 kg, were included in the experiment. The cows were reared in the cattle barn of the Experimental Farm of the Trakia University – Stara Zagora. The animals were in third lactation, between the 2nd and 4th months of lactation. Ultrasound examinations of the mammary gland was made through transcutaneous approach with linear transducer at a frequency of 10.0 MHz. The 3D sonography at the top of the teat was characterized by a clear visualization of the morphological structures papillary orifice, teat canal and rosette of Furstenberg. Above them, in the three-dimensional image were differentiated three-layer construction of the teat wall, as well as milk in the teat cistern. At the boundary between teat and gland cistern of the mammary gland, as clear rounded structures in 3D images were visualized vessels of the Furst-enberg’s venous ring. When examining the body of the udder, three-dimensional ultrasonography allowed characterization of lactiferous ducts in gland cistern and normal mammary parenchyma. Our results indicate that 3D ultrasonography of the mammary gland in dairy cows allows detailed imaging of the morphological structures located therein. This will lead to more accurate diagnosis and prognosis in cases of pathological changes localized in teat and mammary parenchyma of the udder.

ABSTRACT

The role of platelet-rich plasma (PRP) as a promoter of bone union remains controversial. The purpose of this study is to investigate the effect of PRP on non-union femur fracture in a dog. This is a case of a 3 year old mongrel dog with femur fracture. Following unsuccessful treatment of the fracture with dynamic compression plate and external bone fixation, PRP was injected through the skin three times every 10 days in the region of the fracture line. One month after the last injection, there was union between the bone fragments. The administration of PRP in the event of unsuccessful union between bone fragments stimulates bone union.

 

Key words: dog, bone non-union, platelet-rich plasma.
