What Is Pneumocystis Carinii Pneumonia?

Pneumocystis carinii is referred to as pneumocystis, which is widely present in the lung tissues of humans and other mammals and can cause pneumocystis pneumonia, or pneumocystis. Pneumocystis carinii is an opportunistic parasite that threatens human health. Pneumocystis carinii is a parasitic disease caused by lung epithelial cells in mice, dogs, pigs, sheep, rabbits, and humans. Pneumocystis carinii was found in guinea pig lung tissue sections infected with Trypanosoma solani in 1909, and its classification status has not been determined. The ultrastructure found that the wall of the sporozoite was fungal, and the internal structure was related to the protozoa. The history of development has not been identified, but it has a sporadic epidemic and is found in Europe and the Americas. Rodents may be the source of infection, and dogs may be the storage host.

Pneumocystis carinii Delanoe et Delanoe (1912)

Pneumocystis carinii is a eukaryotic single-celled organism, and its taxonomic status is unclear. There are two main types in life history, namely trophozoites and cysts. In Gibbs-stained specimens, the trophozoites are polymorphic, 2-5 & micro; m in size, the cytoplasm is light blue, and the nuclei are dark purple. The capsule is round or oval, with a diameter of 4-6 & micro; m, slightly smaller than

The development of Pneumocystis carinii in human and animal lung tissues is basically clear, but the developmental stage outside the host is not fully understood. It is believed that the cysts of the worms are transmitted by air and enter the lungs. Animal experiments confirm its presence

Most healthy people are infected with the worm, which is a recessive infection, asymptomatic, when the host

World-wide distribution, first spread in Europe after World War II, thousands of cases were reported, and later in the Americas, Asia, Oceania, Africa. More than 10 cases have been reported in Chinese literature.

The epidemic often occurs in

1. Etiology diagnosis can collect sputum or bronchial secretion smear microscopy, but the positive rate is very low, the application of bronchial irrigation can improve

Pneumocystis carinii is widely distributed in nature, and can be parasitic in many animals, such as rats, rabbits, cats, dogs, pigs, horses, monkeys, etc., or in healthy humans. The natural habitat may be soil. Patients with this disease should be isolated to avoid cross infection. Strengthen the testing of blood products without abuse of hormones and immunosuppressants. For suspicious patients, early treatment should be used. Some people try prophylactic drugs and use compound Xinnuoming with certain effects.

Opportunity caused by severe pneumocystis infection

Pneumocystis carinii disease caused by Pneumocystis carinii is very high if it is not treated in time, and if it is treated early, it can survive 60% -80%. Commonly used drugs are pentaneamidine, pyrimethamine, and compound sinomine. In most Chinese hospitals, the addition of sulfathiazole (ST) mixture when treating leukemia has a good effect on the prevention of Pneumocystis carinii pneumonia.
