How is Microsporidia treated?
The most commonly used medications for microsporidiosis include albendazole (Albenza) and fumagillin. For patients with diarrhea and dehydration, intravenous fluid administration and electrolyte repletion may be necessary. Dietary and nutritional regimens may also assist with chronic diarrhea.
What does trichrome stain detect?
Trichrome Staining Procedure The permanent stained smear facilitates detection and identification of cysts and trophozoites and affords a permanent record of the protozoa encountered. Small protozoa, missed by wet mount examinations (of either unconcentrated or concentrated samples) are often seen on the stained smear.
Are Microsporidia protozoa?
Microsporidia are obligate intracellular protozoal parasites that infect a variety of cell types in many different species of animals. These organisms were first described in 1857, when recognized as a cause of disease in nonhuman hosts.
What parasites are acid-fast?
The oocyst walls of Cryptosporidium, Toxoplasma, and Eimeria are each acid-fast. The oocyst walls of Cryptosporidium and Eimeria fall apart when treated with organic solvents.
What are the symptoms of microsporidia?
Watery diarrhea is a main symptom of microsporidiosis, along with abdominal pain, weight loss, loss of appetite, dehydration, and passing gas (flatulence). If the disease spreads to other body parts, symptoms can include inflammation of the brain, eye infections, sinus infections, and muscle aches, among others.
What is the infective stage of microsporidia?
The infective form of microsporidia is the resistant spore and it can survive for a long time in the environment . The spore extrudes its polar tubule and infects the host cell . The spore injects the infective sporoplasm into the eukaryotic host cell through the polar tubule .
What is the infective stage of microsporidia in the stool?
The infective form of microsporidia is the resistant spore and it can survive for an extended period of time in the environment. The spore extrudes its polar tubule and infects the host cell. The spore injects the infective sporoplasm into the eukaryotic host cell through the polar tubule.
