PROTOZOAL DISEASES OF ANIMALS:Pathogens of these diseases are protozoa, piroplasma for example, parasites in the red blood cells (erythrocytes, leukocytes). Sick many species of wild and domestic animals — large and small cattle, horses, pigs, dogs etc. periplasmic Vectors are ticks. The simplest are also the causative agents of Eimeria, toxoplasmosis, sarcocystosis and other diseases.
DISEASES CAUSED BY INSECTS:Insects can be vectors of infectious and invasive diseases, as well as cause independent of the disease. For example, Ovodova disease, sipunculidae (lice), etc. Many of the insects are pests of animal products — carpet beetle, moth etc.
Dear Peter,I’m writing to tell you about what happened to me last week while I 1) was visiting my aunt who lives by sea. One afternoon I 2) was taking her dog for a walk by the cliffs when I 3) noticed a girl who 4) was climbing a tree by the edge of the cliff. As she 5)was hanging there, the branch suddenly 6) broke and the girl 7) fell over the edge. I 8) ran to the edge, but although the girl 9) was shouting for help, I 10) wasn't able to see her. I 11) was thinking about what to do when a man 12) came along the cliff path. I 13) explained what had happened and while he 14)went for help I 15)was talking to the girl. Well, everything 16) ended happily. The girl was rescued and her parents17) thanked me by giving me a large bunch of flowers. The story 18) was in the newspaper too! That’s all my news – write and tell me yours soon.
I am fond of sports. Sports make us stronger and healthier. Many people do sports, so do I. I like to swim in the swimming pool and in the sea in the summer. I also like badminton and volleyball. Cycling is another favourite sport of mine. There are also mental sports, chess for example. Chess games improve the work of our brain, so this game is very useful too. In winter I prefer skiing. It is very good to ski in the fresh winter air. But we must remember that any sport is good if you practise it regularly.
