Microfilaria

 

                                                           Microfilaria

There are three different types of filarial species that can cause lymphatic filariasis in human. Most of the infections worldwide are cause by wuchereria Bancroft. In Asia, The disease can also be caused by Borgia Malaya and Borgia Timor.

The infusion spreads from person to person by mosquito bites. The adult worm live in the human lymph vessels, mates and produces millions of microscopic worms, also known as microfilaria.

Microfilaria circulate in the person’s blood and infect the mosquito when it bites a person who is infected.

Microfilaria grow and develop in the Mosquito. When the mosquito bites another person, the larval worms pass from the mosquito into the human skin, and travel to the lymph vessels. They grow into adult worms a process that takes 6 months or more. An adult worm lives for about 5-7 years.

The adult worms mate and release millions of microfilaria into the blood. People with microfilariae in their blood can serve as a source of infections to others.

Lymphatic filarial affect 120 million person in 72 countries throughout the tropics and sub-tropics of Asia , Africa , the Western pacific , and parts of the Caribbean and South America.

In the American only four countries are currently known to be endemic , Haiti , the Dominican Republic , Guyana and Brazil. In the United states , Charleston , South Carolina , was last known place with lymphatic filaria . The infection disappeared early in  the 20th century. Currently cant get infected in the United states .

Signs & Symptoms of Microfilaria

Rericulocyte Staining process

  Rericulocyte Staining process A reticulocyte stain is a technique a day of Highlight RNA in reticulocytes, A type oc Immuture RBC. This stain commonly use in Hematology department in pathology lab. Edta sample mixed with Reticulocyte staining Solution(Methylene blue) ↓ After Mixed incubate at room temperature. ↓ Prepare   a blood smears ↓ Wait A slide Air-dried the smear ↓ Examined under microscope ↓ The number of reticulocyte count in the patient blood sample is countyed and expressed a percentage   The stain show the RNA in reticulocytes as a blue colour against the pink colour of the rest of the cell. The pattern of the blue colour indicatye the stage of the reticulocyte A hight reticulocyte count can indicate that immutur red blood cells are not surviving longenough, & that the bone marrow needs to increase production. The reticulocyte count is an important role of monitoring of red blood cellssurvival & formation activity o...

MICROSCOPE

                                     MICROSCOPE Introduction of microscope The microscope is indispensable for a clinical laboratory technician. It is very important to have a sound knowledge of the microscope which is going to be a constant comparing in his daily work. To obtain desired magnification for visualizing the objects, the scientists did untiring efforts. The world microscope is derived from two Greek words - ''micro'' (small) and ''scope'' (view). Simple microscope discoveries by Anthony von Leeuwenhoek (1632-1723) and subsequently compound microscope by Robert Hook (1635-1703) were made. It is an instrument by which very small things can be seen which are not seen by the necked eye. This is done by producing an enlarged and well defined image of the objects by a system of lens. Principle of microscope The light beam, which falls on the object, p...
