Entamoeba species of N. fowler can form bursa, but flagella can not. F. natual Amoeba is a thermophilic trophozoite whose trophozoite grows best at 37-45°C and rapidly dies at 0-4°C. The cysts have strong resistance and are still active at 51-65°C for 8 months. They can survive at -20°C for more than 4 months. The cysts also tolerate high concentrations of free chlorine. When a person swims in rivers, lakes, ponds or wash their nose with nausea, the Nagalis amoeba enters the nasal cavity. After proliferating, they pass through the nasal mucosa and sieve-like plates, enter the brain along the olfactory nerve, and invade the central nervous system (CNS). Causes primary amoebic meningoencephalitis (PAM). Its invasiveness may be mainly due to the production of toxins or cytolytic substances to enhance phagocytic activity, phospholipase A and lysosomal enzymes on the surface of the worm promote disease. The incidence of primary amoebic meningoencephalitis is rapid and the condition is rapidly developing. Symptoms such as headache, fever, vomiting, etc., are rapidly transferred to cockroaches, convulsions, and coma. They can die within a week as soon as possible. The damage is mainly manifested in acute and extensive hemorrhagic necrotizing meningoencephalitis, with a large number of trophozoites in cerebrospinal fluid and lesion tissues. The susceptibility factors of the host may lack IgA, and the mucosal defense function is weakened. Acanthamoeba are more widely distributed and often found in respiratory secretions. The primary site of the lesion causes inflammation and granulomas in the skin or eyes, lungs, stomach, intestines, and ears. In the case of host immune suppression or attenuation, it may be transmitted to the central nervous system and cause granulomatous amoebic encephalitis ( GAE). The damage is mostly chronic granulomatous lesions; therefore, the course of the disease is longer and can reach 18-120 days. A few of the illnesses were acute and died within 10 to 14 days. Neurological signs showed focal unilateral lesions with severe focal necrosis and edema. Patients have headaches, fever, vomiting, stiff neck, dizziness, drowsiness, confusion, ataxia, and coma and death. However, Acanthamoeba does not metastasize to the brain and it is generally not fatal. A few can be self-healing. Experimental Observation and Diagnosis Editing 1. Entamoeba histolytica cyst (1) cyst (Iron hematoxylin stain): Observed under the oil microscope, cysts round, diameter 5 to 20 concave, wall clear, nuclear dyed blue-black, round, From 1 to 4, the nucleolus are small and mostly located in the center. The size of the nucleus is uniform and neatly arranged. The nuclear characteristics are of great significance in identifying species. In the cytoplasm, glycogen is slightly soluble during the staining process and becomes a glycogen vesicle. Mimic chromosomes are seen in immature cysts.
