The aim of the research was to investigate the possibility of using oral medicines for the treatment of animals with skin mycoses. The administration of oral azole antifungal Itraconazole was conducted on guinea pigs. In the light microscopy investigation during treatment of guinea pigs with Itraconazole, mycelium were not observed 4 days after the time of the administration of the drug, both in the stratum corneum of the epidermis and in hair sheaths. Neither was mycelium confirmed in the subcutaneous layer. Only parakeratose, hyperkeratose was observed, as well as a small degree of akantose. The investigation with the use scanning microscope made it possible to additionally affirm the presence on the top of scraps of spherical forms the accumulations of drops of fat which is characteristic for azole antifungals. The administration of oral azole antifungal causes the rapid regression of pathological changes in the deep layers of the skin. Therapy of this type can be useful in veterinary medicine.
Dermatophytes have the ability to invade keratinized tissue (hair, nails and skin). The invasion elicits a host response ranging from mild to severe. Local anti-dermatophyte immunity includes activation of macrophages, sensitization of T lymphocytes and the production of antibodies. Dermatophytes are eliminated from the skin by a cell-mediated immune reaction. Although antibodies play a small part in dealing with dermatophytosis, they somehow support fagocytosis and suppress adhesion of the fungus to host cells. The development of cell-mediated immunity correlated with delayed hypersensitivity is associated with clinical cure. Dermatophytoses are considered as an important epidemiological problem. Therefore, all the latest efforts to develop an effective vaccine against ringworm are significant. However, the immunology of the dermatophyte infection still remains to be comprehensively examined.
The research material comprised the livers collected post mortem and ante mortem from dogs and cats, as well as farm animals, in the Lublin Province during 2005-2009.The material fixed in 4% buffered formalin was subsequently dehydrated and paraffin-embedded. The 4-micron-thick sections were stained with haematoxylin and eosin (HE). The most pathological changes in dogs and cats had occurred in animals over 11-years-of-age. Angiosarcoma and hepatocellular carcinoma were the most frequent neoplastic changes reported in these animals. This is due to significant pollution of the urban environment where most of these animals came from. Nitrosamines and chloral hydrate play a significant role here. Adipose degeneration and necrosis predominated among the non-neoplastic lesions recognized in all animals is often due to dietary errors committed by pet owners. The influence of animal viral cirrhosis of the liver is not as well understood in animals as in humans and requires further study.
Oncotherapy of tumors in dogs and cats is often associated with many side effects. This result is connected with the considerable fall of immunity through the application of radiotherapy as well as chemotherapy. Organ mycoses are typical complications concerning livers, spleen, as well as the lungs evoked by fungus Candida, Aspergillus as well as Cryptococcus. Diagnosis using PCR is a method primarily approved due to its short time test and a high specificity. The avoidance of organ mycosis should be based on the introduction of suitable preventive programs connected with empirical treatment.
The aim of the examinations was to define the kinds of neoplastic changes in dog’s prostate using biopsy techniques and histopathological method. Fifty dog’s prostates which were received during the post mortem examination were used for the examination. In 14 cases neoplastic changes were diagnosed, 4 cases evidenced purulent inflammation, 17 no neoplastic growth, and 15 prostates had a normal structure. In this article these two described below methods of pathomorphological diagnosis are compared, simultaneously demonstrating their usefulness and the complete agreement of received results.
The study aimed at the analysis of splenic pathologic lesions in mix-breed dogs of varied age and sex in the Lublin Province in 2005-2008. The research material comprised 33 spleen specimens collected both during surgery and post mortem. The material was fixed in 4% buffered formalin, dehydrated, and paraffin-embedded. The 4-µm-thick sections were stained with haematoxylin and eosin. The non-cancerous lesions were detected in young dogs under 2 years of age. Angiosarcoma proved to be the most common lesion and accounted for over 36% of total cases, followed by haemangioma recognised in above 27% of all cases. Nodular hyperplasia, hyperaemia, histiocytic sarcomas, haemangiopericytomas, lymphomas, and necrotic lesions were observed in notable minority of cases.
Neoplasms of the esophagus are very rare in dogs. They account for 0.5% of all tumors. In the presented case the development of carcinoma was latent. The first symptoms were hypersalivation, vomiting, the backward flow and difficulty in swallowing of solid food. Subsequently the dog wasn’t able to swallow fluids. Hyperleucocytosis, lymphocytosis, monocytosis, anemia and elevated alkaline phosphatase level in the serum suggested tumor growth. An esophagoscopy was conducted as was oesophagostenosis: a tumor with hemorrhagic focuses, ulcer formations and erosions were observed. The dog was subjected to euthanasia. Specimens for histological examination were taken. The histology and immunohistological analysis confirmed the diagnosis of squamosus cell carcinoma.
Determination of the exact time of death of a human being or animal is extremely important for investigations conducted by law enforcement agencies. The development of a single model of tests and analysis of the site of the incident would be a breakthrough for forensic and veterinary medicine in estimating the exact time of death. Microorganisms play a key role in the putrefaction process. Each stage of decomposition is characterized by the colonization of tissues by different microbial taxa. The objective of the study was to determine the suitability of microbiological tests for establishing the time of death, using the example of the gastrocnemius muscle in a dog (German Shepherd). The results of the study showed that sporulating aerobic bacteria of the species Bacillus cereus, as well as anaerobic bacteria, played a major role in the putrefaction process. No E. coli were found in the material. The first bacterial colonies belonging to the Bacillus cereus group were observed on the 7th day after the death of the animal, and their quantitative growth persisted throughout the study period, i.e. until the 21st day after death. The analysis carried out in this study shows that Bacillus cereus bacteria appear much sooner than anaerobic bacteria.
