What are the basic 5 types of diseases?
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases. The most widely used classifications of disease are (1) topographic, by bodily region or system, (2) anatomic, by organ or tissue, (3) physiological, by function or effect, (4) pathological, by the nature of the disease process, (5) etiologic (causal), (6) juristic, by speed of advent of death, (7) epidemiological, and .There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.The Top 10 list includes, in rank order, (1) Magnaporthe oryzae; (2) Botrytis cinerea; (3) Puccinia spp. Fusarium graminearum; (5) Fusarium oxysporum; (6) Blumeria graminis; (7) Mycosphaerella graminicola; (8) Colletotrichum spp. Ustilago maydis; (10) Melampsora lini, with honourable mentions for fungi just .Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right.
What are the 12 diseases?
Specifically, the chapters are devoted to the study of cholera, smallpox, bubonic plaque, syphilis, tuberculosis, malaria, fever, influenza, and AIDS. These diseases can be caused by various pathogens, including bacteria, viruses, fungi, and parasites, and are often communicable. Examples of endemic infections include cholera, malaria, and schistosomiasis, which are particularly common in developing countries with poor sanitation.The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology.
What are the four types of plant disease?
Common plant diseases include fungal diseases, bacterial diseases, and viral diseases. Fungal Diseases: Black spot, Rust, Botrytis blight, Powdery mildew. Bacterial Diseases: Black rot, Bacterial canker, Soft rot, Leaf spot wilt, Blight. Fungal diseases are the most common infection in plants. There are some characteristic symptoms, or observable effects of the disease, in plants. Fungi infections can be recognized by symptoms like spots on plant leaves, yellowing of leaves, and birds-eye spots on berries.Symptoms of bacterial infection in plants are much like the symptoms in fungal plant disease. They include leaf spots, wilts, scabs, cankers and rots of roots and fruit; the most common symptom being leaf spots. In extreme cases, dark necrotic spots can spread to an entire leaf and kill it.The rusts are a group of fungal diseases affecting the aerial parts of plants. Leaves are affected most commonly, but rust can also be found occasionally on stems and even flowers and fruit. The spore pustules produced by rusts vary in colour, according to the rust species and the type of spore that it is producing.On the other hand, pathogenic fungi cause plant diseases such as anthracnose, leaf spot, rust, wilt, blight, coils, scab, gall, canker, damping-off, root rot, mildew, and dieback.
What is the 5 and 6 disease?
Fifth (erythema infectiosum) and sixth (roseola infantum) diseases are common rash illnesses of childhood that have long been recognized in clinical medicine. The discovery of the viruses that cause these illnesses has revealed relationships with other syndromes. How Long Does Roseola Last? The fever of roseola lasts from 3 to 5 days, followed by a rash lasting from hours to a few days.Roseola infantum, also known as exanthema subitum or sixth disease, typically presents in children between six and 12 months of age; ninety percent of cases occur in children younger than two years. This condition is responsible for between 10 and 45 percent of febrile illness in infants.Roseola, also known as sixth disease, usually isn’t serious, and it goes away on its own in a week or so. Treatment of roseola includes cool cloths and medications to reduce fever.
What are the 5 bacterial diseases in plants?
Plant pathogenic bacteria cause many different kinds of symptoms that include galls and overgrowths, wilts, leaf spots, specks and blights, soft rots, as well as scabs and cankers. Chlorosis: Yellowing of normally green tissue due to lack of chlorophyll. Necrosis: The death of plant tissue, which results in dark brown or black spots. Wilting: The drooping of leaves or stems due to water loss. Galls: Abnormal swellings or growths on stems, leaves, or roots.
