Opis:
Cats (Felis catus) have accompanied humans for thousands of years. Together with dogs they have become the most popular species included in the group of so-called accompanying animals. The intention of deliberate breeding of many animal species based on scientific foundations was to create new breeds and improve the existing ones. However, the activities related to cat breeding were not so intense as in the case of dogs. Cats are therefore considered to be more stabilized morphologically and more closely related to their wild ancestors than other domesticated species. The aim of this paper was to present some details of the anatomy of cats which are characteristic of this species, with special reference to those characteristics which significantly differentiate cats from dogs. In the paper the focus was on the anatomy of the skeleton which in cats can be considered an evident adaptation, in the evolution process, to the lifestyle they led. The set of teeth and other elements of the circulatory and digestive systems were described pointing to the presence of papillae filiformes on the tongue which was one of the causes of pilobezoar formation in the stomach. The general anatomy of the respiratory system was discussed with special attention paid to the anatomy of sinus paranasales. The cat's heart was described demonstrating that it is most horizontally and caudaly situated in comparison with other domesticated animal species. Attention was attached to the characteristic anatomy and arrangement of the male reproductive system of this species. The paper provided an explanation of how the eyeball in cats is adapted, due to its specific anatomy, to receive light stimuli in the dark. Also the glands and other products of the skin, like: hair were discussed. Much attention was also put on the anatomy of cat's claws, they are very effective on account of the presence of elastic ligaments which permit cats to extend the claws and retract them in the skin pouch.

Opis:
The bacteria Borrelia burgdorferi is the main cause of Lyme disease (Lyme borreliosis). The vector of the infection are ticks of the genus Ixodes. The most common species in Poland is the tick species Ixodes ricinus. The Lyme disease spirochetes are transmitted to the host directly by the bite of infected ticks feeding on the blood of animals that have the disease. The infection can also occur through the contact with the urine, sperm, saliva, nasal discharge or milk of an infected animal. The source of the B. burgdorferi bacteria are rodents, insect-eating mammals, certain animal species of the family Cervidae or Canidae, birds and lizards. Being tolerant to these bacteria these animals are the source of infection for the feeding ticks. In contrast to the free-living animals the symptoms of Lyme disease may appear in the livestock. However, the symptoms are not characteristic, extremely differentiated and similar to the symptoms of other diseases. Therefore, the clinical tests are of little diagnostic value. In the case of a suspicion of borreliosis the application of laboratory tests is necessary to detect the presence of the bacteria B. burgdorferi or its components in the tested material or on the measurement of the immunological response to the precisely determined antigens of this bacteria.

Opis:
The aim of this work was to present the impact of external pathogens, which, through a disorder of intra-organic homeostasis, lead to permanent and irreversible changes in highly organized integration processes of the central nervous system. In result, changes in behaviour of various animal species are observed. Decrease in psychophysical activity is the main symptom of the strategy allowing to overcome the healing crisis and to survive. In specialist literature this condition is called the "sickness behaviour". In case of presented disease entities, etilogic factors exceed compensation abilities of the system and lead to decease or are an indication for euthanasia. Very frequently, non-specific symptoms in the course of the above mentioned contagious diseases in animals and close contacts of some animal species with humans present a direct threat to people.
