What are Obligate Parasites?

Obligatory parasite. This is an area of medical research. All stages of obligatory parasite growth depend on parasitic life, such as filariasis; or a certain stage of life history must depend on parasitic life, such as that of plasmodium. All developmental stages must be performed in the human body and mosquito, otherwise their life history cannot be completed. Such as hookworms, their larvae live on their own in the soil, but after they develop to filamentous, they must invade the host and live on parasites in order to develop into adults. Studying the evolution, pathogenicity, diagnosis and prevention of obligate parasites provides the basis for the development of the medical field.

Etiological diagnosis can be taken from patients' body fluids, cerebrospinal fluid, and other specimens.

1. The epidemic situation is distributed worldwide, widely exists in a variety of mammals, and the infection of the population is quite common. The infection rate of foreign populations is 0.99% -94%, and the domestic population is generally below 8%. It is estimated that about 1 billion people worldwide are infected by Toxoplasma gondii. Animal breeders, butchers, hunters, skinners, toxoplasma laboratory staff, and veterinarians are more vulnerable to infection due to their greater exposure to toxoplasma. The disease is closely related to patients with acquired immunodeficiency syndrome, or AIDS, and about 5% to 10% of AIDS patients have Toxoplasma gondii infection.

(1) Source of infection: Animals are the main source of this disease, and cats and felines are important sources of infection. The vertical transmission of humans through the placenta is of significance as a source of infection.

(2) Transmission: vertical transmission through the placenta, through the digestive tract, through damaged skin and mucosal arthropods, and through blood transfusion or organ transplantation. Arthropods carrying oocysts also have a certain transmission significance.

(3) Susceptible people: Humans are generally susceptible to Toxoplasma gondii. Fetuses and infants are more susceptible than adults, and patients with tumors and immune dysfunction or impairment are more susceptible than normal people.

In terms of treatment, patients in the acute phase should be treated with drugs in a timely manner, but so far there is no ideal

Drug. Ethylpyrimidine and sulfa drugs such as compound sinomine have inhibitory effects on Toxoplasma gondii in the proliferative phase. The combined use of these two drugs can improve the efficacy. In terms of prevention and control, strengthen the monitoring and isolation of domestic animals, poultry and suspicious animals; strengthen dietary hygiene management, strengthen the meat food hygiene and quarantine system; educate the public not to eat raw or semi-raw meat, eggs, dairy products; Do not touch cats, feces and raw meat. Do not let cats lick their hands, face and food utensils. Regular routine inspections of Toxoplasma to reduce the incidence of congenital Toxoplasmosis.
