CATDOLL : CATDOLL: How is canine coronavirus disease diagnosed?

1. How is canine coronavirus disease diagnosed?

The diagnosis can be confirmed by electron microscopy, virus isolation, fluorescent antibodies and serological tests. Among these methods, electron microscopy is the most accurate and rapid.

The above is about etiological diagnosis. In the absence of conditions, clinical diagnosis can also be made quickly based on the immunization history and clinical symptoms, that is, complete immunization history, severe vomiting, and no obvious changes in stool.

2. How to identify whether chickens have ascariasis?

How to identify and diagnose whether chickens have ascariasis? When there are a small number of ascarids in the intestines of chickens, no obvious symptoms can be seen. When chicks and young chickens under 3 months old are parasitized, the number of ascarids is often large, and the initial symptoms are not obvious. Then they gradually show low spirits, loss of appetite, ruffled feathers, drooping wings, pale beards, visible mucous membranes and legs, slow growth, weight loss and weakness, alternating diarrhea and constipation, and sometimes bloody mucus mixed in the feces.

Adult chickens generally do not show symptoms, but in severe cases, they will have diarrhea, anemia and reduced egg production. Autopsy shows obvious anemia, weight loss, intestinal mucosal congestion, swelling, inflammation and bleeding; local tissue hyperplasia, a large number of protruding parts of the worms can be felt by hand, and the hard contents can be clearly felt to block the intestines. Cutting the intestinal wall shows that many roundworms are twisted together in a rope shape.

3. What are the self-diagnosis standards and identification methods for AIDS?

There are many self-diagnosis standards and identification methods for AIDS, such as observing whether you have been losing weight for no apparent reason in the recent period, accompanied by symptoms of persistent diarrhea, or whether you have secondary immunodeficiency diseases. In addition, due to cortical sex hormones after radiotherapy and chemotherapy, secondary immunodeficiency diseases such as malignant tumors may occur. If any of these items are combined, it can be confirmed that you have AIDS.

4. What is differential diagnosis?

Differential diagnosis is to distinguish other diseases and exclude other possible diagnoses based on the patient's chief complaint, the medical history provided, the existing abnormal signs, and the results of objective laboratory tests. Simply put, differential diagnosis is to exclude the diagnosis of similar diseases. The significance of differential diagnosis is to improve the accuracy of diagnosis and try to avoid or reduce the occurrence of misdiagnosis and missed diagnosis.

5. How to differentiate and diagnose goose plague and goose paramyxovirus disease?

Muscovy duck and goose plague is an acute infectious disease with high contact and mortality caused by goose parvovirus (goose plague virus) in ducklings and goslings. Since the epidemiology, clinical symptoms and pathological changes of the two diseases are similar, in addition to serological methods, differential diagnosis can also be carried out by infection tests using susceptible geese and susceptible ducklings. Five susceptible goslings of about 5 days old or five susceptible ducklings of about 5 days old are injected with the tested diseased material, or the tested goose embryo fluid toxin or duck embryo fluid toxin. If both goslings and ducklings become ill and die, and have characteristic lesions of goose plague, it is caused by goose plague virus; if it only causes the disease and death of ducklings, while the goslings are alive and well, it is caused by Muscovy duck parvovirus, which can be used as an important differential diagnosis method for the two diseases.

6. What are the diagnostic criteria for Norovirus?

Norovirus is diagnosed based on epidemiological data such as the patient's age, region, and season, clinical manifestations, and the results of routine laboratory tests. If the virus's incubation period is 24 to 48 hours, there will be diarrhea, and 50% of patients will also vomit. Excluding common bacteria, parasites, and other pathogens, norovirus can be detected in stool specimens or vomitus.

7. How to differentiate and diagnose laryngeal cancer?

Now we usually do laryngoscopy to check if the vocal cords are smooth. If there is any growth, if it is a polyp, polyps are generally smooth, but some people may have laryngeal cancer, which is a tumor. Generally speaking, the surface of the tumor is rough and not smooth. In medicine, there is a term called vegetative tissue, which is highly suspected of laryngeal cancer. If new vegetative tissue is found, it is generally necessary to take new tissue for pathological examination, that is, pathological biopsy, to determine whether it is laryngeal cancer through biopsy.

8. What are the differential diagnoses for hemoptysis?

Hemoptysis can be differentiated into lung cancer, lung abscess, tuberculosis, bronchiectasis, etc. Pulmonary congestion and myocardial infarction may cause hemoptysis. You need to adjust your mood, avoid eating greasy and spicy food, eat more light and easily digestible food, and pay more attention to rest to avoid worsening of the condition.

9. How to differentiate and diagnose fasciitis?

Fasciitis patients may experience local pain, limited mobility, etc., so generally an X-ray of the local painful area can be taken first to rule out local bone lesions, and an MRI of the painful area can be performed if necessary. Doctors can diagnose fasciitis through physical examination, medical history, and auxiliary examinations. Generally speaking, fasciitis is caused by the patient being in the same position for a long time, resulting in fascial strain. At this time, the main treatment option is to rest, followed by the use of local hot compresses to relieve symptoms.

10. How is Parkinson’s disease diagnosed?

To make a clear diagnosis of Parkinson's disease, a series of examinations are needed, such as CT or MRI of the brain, to rule out other organic diseases that may cause symptoms similar to Parkinson's disease. In addition, a series of examinations related to limb movement, tremor patterns, etc. are also needed.
