Infectious diseases have the ability to spread from sick to healthy people, many diseases develop into epidemics
The shigellas are both enterotoxins (ShET-1) and ShET-2, they alter electrolyte transport in the cells of the colon mucosa, causing increased secretion.
Malaria is a blood-borne infectious disease, caused by the parasite Plasmodium, which is passed from sick to healthy people by the mosquito Anopheles.
Suspected cases of HSV viral encephalitis can detect HSV glycoprotein antigens in CSF.
Due to trauma or surgery to the brain or spine area, or due to infection with a spinal puncture, common pathogens are Staphylococcus aureus, Streptococcus aureus, bacillus blue pus
Membrane cocci attach to the non-villi epithelial cells in the upper respiratory tract by the receptor, a membrane protein.
Ages susceptible to the disease are children under 15 years of age, the index of infection is about 15-20% in children who do not have immunity. new-born babies do not get sick because they have passive antibodies passed from their mother.
The virus is resistant to a solution of Ether Phenol Glycerine alcohol and ice. Temperatures above 550C and solutions of Methylene Blue, potassium permanganate, and ultraviolet light inactivate the smallpox virus quickly.
Young children can get chickenpox after contact with an adult with Herpes Zoster, but adults rarely get Herpes Zoster after contact with a child with chickenpox.
An RNA group virus of the Paramyxovirus family. There is pathogenicity to the glands (exocrine) and nerve
When there is measles, the virus stimulates the body to produce antibodies. Antibodies appear 2-3 days after the onset of the rash and persist for a long time. Immunity in measles is stable immunity.
In recent years, the severe acute respiratory viral infection (SARS) epidemic, high mortality rate, tends to increase and is a current problem in world health.
Easily destroyed at normal temperature, well-tolerated at low temperatures. Viruses have 3 types of antigens.
The disease often spreads, sometimes translated into small groups such as kindergartens, kindergartens, and junior high schools
The pathogenesis of diffuse hepatic necrosis is associated with lipid redox, the Lysosome proteolytic enzymes, the immunological state, and the autoimmune process.
Hepatitis B viruses, hepatitis C and hepatitis caused by HBV and HDV are viruses that easily progress to chronic hepatitis, there is no other virus excluded.
Because there are different types of hepatitis viruses, these viruses belong to different virus families, different routes of transmission, pathogenicity, disease progression, and so on.
Cholera is eliminated in the stool right from the incubation stage, but most in the diarrhoea stage. Patients with cholera can eliminate 107-108 bacteria/gram of fences.
Salmonella has good vitality and resistance. In broth, soil can survive for several months, in normal water: 2-3 weeks, in ice: 2-3 months, in faeces: several weeks.
There are clinical manifestations of malaria, but the parasite has not been found in the blood, and after eliminating fever from other causes.
The small active form that lives in the lumen of the colon has a size ranging from 8 to 25 micrometres, moving more slowly than the large active form, in the cytoplasm, there is no erythrocyte.
Gram-negative sepsis is usually secondary to the gastrointestinal tract, genital urinary tract, bile, liver, hospital procedures, catheter, tracheostomy, peritoneal dialysis.
Today, many modern medical techniques such as ELISA, PCR, CT-scanner ... have been studied to make the diagnosis of TB meningitis more accurate.
Bacteria that secrete endotoxins (Pertussis toxin) include two types: heat-resistant and heat-resistant, lymphocytic factor (LPF), histamine-sensitive factor (HSF), and FHA agglutination factor.
Oral poisoning is caused by eating food that has been contaminated by pathogenic bacteria. Typical is food poisoning caused by Salmonella.
